+        visible on the css bus. A device driver, however, will never interact

 will fail enabling MSI-X on its hardware device when it calls the function
 pci_enable_msix().
 
-5.3.2 Handling MSI-X allocation
-
-Determining the number of MSI-X vectors allocated to a function is
-dependent on the number of MSI capable devices and MSI-X capable
-devices populated in the system. The policy of allocating MSI-X
-vectors to a function is defined as the following:
-
-#of MSI-X vectors allocated to a function = (x - y)/z where
-
-x =     The number of available PCI vector resources by the time
-        the device driver calls pci_enable_msix(). The PCI vector
-        resources is the sum of the number of unassigned vectors
-        (new) and the number of released vectors when any MSI/MSI-X
-        device driver switches its hardware device back to a legacy
-        mode or is hot-removed. The number of unassigned vectors
-        may exclude some vectors reserved, as defined in parameter
-        NR_HP_RESERVED_VECTORS, for the case where the system is
-        capable of supporting hot-add/hot-remove operations. Users
-        may change the value defined in NR_HR_RESERVED_VECTORS to
-        meet their specific needs.
-
-y =     The number of MSI capable devices populated in the system.
-        This policy ensures that each MSI capable device has its
-        vector reserved to avoid the case where some MSI-X capable
-        drivers may attempt to claim all available vector resources.
-
-z =     The number of MSI-X capable devices populated in the system.
-        This policy ensures that maximum (x - y) is distributed
-        evenly among MSI-X capable devices.
-
-Note that the PCI subsystem scans y and z during a bus enumeration.
-When the PCI subsystem completes configuring MSI/MSI-X capability
-structure of a device as requested by its device driver, y/z is
-decremented accordingly.
-
-5.3.3 Handling MSI-X shortages
-
-For the case where fewer MSI-X vectors are allocated to a function
-than requested, the function pci_enable_msix() will return the
-maximum number of MSI-X vectors available to the caller. A device
-driver may re-send its request with fewer or equal vectors indicated
-in the return. For example, if a device driver requests 5 vectors, but
-the number of available vectors is 3 vectors, a value of 3 will be
-returned as a result of pci_enable_msix() call. A function could be
-designed for its driver to use only 3 MSI-X table entries as
-different combinations as ABC--, A-B-C, A--CB, etc. Note that this
-patch does not support multiple entries with the same vector. Such
-attempt by a device driver to use 5 MSI-X table entries with 3 vectors
-as ABBCC, AABCC, BCCBA, etc will result as a failure by the function
-pci_enable_msix(). Below are the reasons why supporting multiple
-entries with the same vector is an undesirable solution.
-
-        - The PCI subsystem cannot determine the entry that
-          generated the message to mask/unmask MSI while handling
-          software driver ISR. Attempting to walk through all MSI-X
-          table entries (2048 max) to mask/unmask any match vector
-          is an undesirable solution.
-
-        - Walking through all MSI-X table entries (2048 max) to handle
-          SMP affinity of any match vector is an undesirable solution.

-void kset_put(struct kset *s);
 
 These are just wrappers around the respective kset_* functions.

-Introduction to NAPI
-====================
-
-NAPI is a proven (www.cyberus.ca/~hadi/usenix-paper.tgz) technique
-to improve network performance on Linux. For more details please
-read that paper.
-NAPI provides a "inherent mitigation" which is bound by system capacity
-as can be seen from the following data collected by Robert on Gigabit 
-ethernet (e1000):
-
- Psize    Ipps       Tput     Rxint     Txint    Done     Ndone
- ---------------------------------------------------------------
-   60    890000     409362        17     27622        7     6823
-  128    758150     464364        21      9301       10     7738
-  256    445632     774646        42     15507       21    12906
-  512    232666     994445    241292     19147   241192     1062

-Legend:
-"Ipps" stands for input packets per second. 
-"Tput" == packets out of total 1M that made it out.
-"txint" == transmit completion interrupts seen
-"Done" == The number of times that the poll() managed to pull all
-packets out of the rx ring. Note from this that the lower the
-load the more we could clean up the rxring
-"Ndone" == is the converse of "Done". Note again, that the higher
-the load the more times we couldn't clean up the rxring.
-
-Observe that:
-when the NIC receives 890Kpackets/sec only 17 rx interrupts are generated. 
-The system cant handle the processing at 1 interrupt/packet at that load level. 
-At lower rates on the other hand, rx interrupts go up and therefore the
-interrupt/packet ratio goes up (as observable from that table). So there is
-possibility that under low enough input, you get one poll call for each
-input packet caused by a single interrupt each time. And if the system 
-cant handle interrupt per packet ratio of 1, then it will just have to 
-chug along ....
-
-
-0) Prerequisites:
-==================
-A driver MAY continue using the old 2.4 technique for interfacing
-to the network stack and not benefit from the NAPI changes.
-NAPI additions to the kernel do not break backward compatibility.
-NAPI, however, requires the following features to be available:
-
-A) DMA ring or enough RAM to store packets in software devices.
-
-B) Ability to turn off interrupts or maybe events that send packets up 
-the stack.
-
-NAPI processes packet events in what is known as dev->poll() method.
-Typically, only packet receive events are processed in dev->poll(). 
-The rest of the events MAY be processed by the regular interrupt handler 
-to reduce processing latency (justified also because there are not that 
-many of them).
-Note, however, NAPI does not enforce that dev->poll() only processes 
-receive events. 
-Tests with the tulip driver indicated slightly increased latency if
-all of the interrupt handler is moved to dev->poll(). Also MII handling
-gets a little trickier.
-The example used in this document is to move the receive processing only
-to dev->poll(); this is shown with the patch for the tulip driver.
-For an example of code that moves all the interrupt driver to 
-dev->poll() look at the ported e1000 code.
-
-There are caveats that might force you to go with moving everything to 
-dev->poll(). Different NICs work differently depending on their status/event 
-acknowledgement setup. 
-There are two types of event register ACK mechanisms.
-        I)  what is known as Clear-on-read (COR).
-        when you read the status/event register, it clears everything!
-        The natsemi and sunbmac NICs are known to do this.
-        In this case your only choice is to move all to dev->poll()
-
-        II) Clear-on-write (COW)
-         i) you clear the status by writing a 1 in the bit-location you want.
-                These are the majority of the NICs and work the best with NAPI.
-                Put only receive events in dev->poll(); leave the rest in
-                the old interrupt handler.
-         ii) whatever you write in the status register clears every thing ;->
-                Cant seem to find any supported by Linux which do this. If
-                someone knows such a chip email us please.
-                Move all to dev->poll()
-
-C) Ability to detect new work correctly.
-NAPI works by shutting down event interrupts when there's work and
-turning them on when there's none. 
-New packets might show up in the small window while interrupts were being 
-re-enabled (refer to appendix 2).  A packet might sneak in during the period 
-we are enabling interrupts. We only get to know about such a packet when the 
-next new packet arrives and generates an interrupt. 
-Essentially, there is a small window of opportunity for a race condition
-which for clarity we'll refer to as the "rotting packet".
-
-This is a very important topic and appendix 2 is dedicated for more 
-discussion.
-
-Locking rules and environmental guarantees
-==========================================
-
--Guarantee: Only one CPU at any time can call dev->poll(); this is because
-only one CPU can pick the initial interrupt and hence the initial
-netif_rx_schedule(dev);
-- The core layer invokes devices to send packets in a round robin format.
-This implies receive is totally lockless because of the guarantee that only 
-one CPU is executing it.
--  contention can only be the result of some other CPU accessing the rx
-ring. This happens only in close() and suspend() (when these methods
-try to clean the rx ring); 
-****guarantee: driver authors need not worry about this; synchronization 
-is taken care for them by the top net layer.
--local interrupts are enabled (if you dont move all to dev->poll()). For 
-example link/MII and txcomplete continue functioning just same old way. 
-This improves the latency of processing these events. It is also assumed that 
-the receive interrupt is the largest cause of noise. Note this might not 
-always be true. 
-[according to Manfred Spraul, the winbond insists on sending one 
-txmitcomplete interrupt for each packet (although this can be mitigated)].
-For these broken drivers, move all to dev->poll().
-
-For the rest of this text, we'll assume that dev->poll() only
-processes receive events.
-
-new methods introduce by NAPI
-=============================
-
-a) netif_rx_schedule(dev)
-Called by an IRQ handler to schedule a poll for device
-
-b) netif_rx_schedule_prep(dev)
-puts the device in a state which allows for it to be added to the
-CPU polling list if it is up and running. You can look at this as
-the first half of  netif_rx_schedule(dev) above; the second half
-being c) below.
-
-c) __netif_rx_schedule(dev)
-Add device to the poll list for this CPU; assuming that _prep above
-has already been called and returned 1.
-
-d) netif_rx_reschedule(dev, undo)
-Called to reschedule polling for device specifically for some
-deficient hardware. Read Appendix 2 for more details.
-
-e) netif_rx_complete(dev)
-
-Remove interface from the CPU poll list: it must be in the poll list
-on current cpu. This primitive is called by dev->poll(), when
-it completes its work. The device cannot be out of poll list at this
-call, if it is then clearly it is a BUG(). You'll know ;->
-
-All of the above methods are used below, so keep reading for clarity.
-
-Device driver changes to be made when porting NAPI
-==================================================
-
-Below we describe what kind of changes are required for NAPI to work.
-
-1) introduction of dev->poll() method 
-=====================================
-
-This is the method that is invoked by the network core when it requests
-for new packets from the driver. A driver is allowed to send upto
-dev->quota packets by the current CPU before yielding to the network
-subsystem (so other devices can also get opportunity to send to the stack).
-
-dev->poll() prototype looks as follows:
-int my_poll(struct net_device *dev, int *budget)
-
-budget is the remaining number of packets the network subsystem on the
-current CPU can send up the stack before yielding to other system tasks.
-*Each driver is responsible for decrementing budget by the total number of
-packets sent.
-        Total number of packets cannot exceed dev->quota.
-
-dev->poll() method is invoked by the top layer, the driver just sends if it 
-can to the stack the packet quantity requested.
-
-more on dev->poll() below after the interrupt changes are explained.
-
-2) registering dev->poll() method
-===================================
-
-dev->poll should be set in the dev->probe() method. 
-e.g:
-dev->open = my_open;
-.
-.
-/* two new additions */
-/* first register my poll method */
-dev->poll = my_poll;
-/* next register my weight/quanta; can be overridden in /proc */
-dev->weight = 16;
-.
-.
-dev->stop = my_close;
-
-
-
-3) scheduling dev->poll()
-=============================
-This involves modifying the interrupt handler and the code
-path which takes the packet off the NIC and sends them to the 
-stack.
-
-it's important at this point to introduce the classical D Becker 
-interrupt processor:
-
-------------------
-static irqreturn_t
-netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
-{
-
-        struct net_device *dev = (struct net_device *)dev_instance;
-        struct my_private *tp = (struct my_private *)dev->priv;
-
-        int work_count = my_work_count;
-        status = read_interrupt_status_reg();
-        if (status == 0)
-                return IRQ_NONE; /* Shared IRQ: not us */
-        if (status == 0xffff)
-                return IRQ_HANDLED;      /* Hot unplug */
-        if (status & error)
-                do_some_error_handling()
-        
-        do {
-                acknowledge_ints_ASAP();
-
-                if (status & link_interrupt) {
-                        spin_lock(&tp->link_lock);
-                        do_some_link_stat_stuff();
-                        spin_lock(&tp->link_lock);
-                }
-                
-                if (status & rx_interrupt) {
-                        receive_packets(dev);
-                }
-
-                if (status & rx_nobufs) {
-                        make_rx_buffs_avail();
-                }
-                        
-                if (status & tx_related) {
-                        spin_lock(&tp->lock);
-                        tx_ring_free(dev);
-                        if (tx_died)
-                                restart_tx();
-                        spin_unlock(&tp->lock);
-                }
-
-                status = read_interrupt_status_reg();
-
-        } while (!(status & error) || more_work_to_be_done);
-        return IRQ_HANDLED;

-}
-
----------------------------------------------------------------------
-
-
-We note several things from above:
-
-I) Any interrupt source which is caused by arriving packets is now
-turned off when it occurs. Depending on the hardware, there could be
-several reasons that arriving packets would cause interrupts; these are the
-interrupt sources we wish to avoid. The two common ones are a) a packet 
-arriving (rxint) b) a packet arriving and finding no DMA buffers available
-(rxnobuff) .
-This means also acknowledge_ints_ASAP() will not clear the status
-register for those two items above; clearing is done in the place where 
-proper work is done within NAPI; at the poll() and refill_rx_ring() 
-discussed further below.
-netif_rx_schedule_prep() returns 1 if device is in running state and
-gets successfully added to the core poll list. If we get a zero value
-we can _almost_ assume are already added to the list (instead of not running. 
-Logic based on the fact that you shouldn't get interrupt if not running)
-We rectify this by disabling rx and rxnobuf interrupts.
-
-II) that receive_packets(dev) and make_rx_buffs_avail() may have disappeared.
-These functionalities are still around actually......
-
-infact, receive_packets(dev) is very close to my_poll() and 
-make_rx_buffs_avail() is invoked from my_poll()
-
-4) converting receive_packets() to dev->poll()
-===============================================
-
-We need to convert the classical D Becker receive_packets(dev) to my_poll()
-
-First the typical receive_packets() below:
--------------------------------------------------------------------
-
-/* this is called by interrupt handler */
-static void receive_packets (struct net_device *dev)
-{
-
-        struct my_private *tp = (struct my_private *)dev->priv;
-        rx_ring = tp->rx_ring;
-        cur_rx = tp->cur_rx;
-        int entry = cur_rx % RX_RING_SIZE;
-        int received = 0;
-        int rx_work_limit = tp->dirty_rx + RX_RING_SIZE - tp->cur_rx;
-
-        while (rx_ring_not_empty) {
-                u32 rx_status;
-                unsigned int rx_size;
-                unsigned int pkt_size;
-                struct sk_buff *skb;
-                /* read size+status of next frame from DMA ring buffer */
-                /* the number 16 and 4 are just examples */
-                rx_status = le32_to_cpu (*(u32 *) (rx_ring + ring_offset));
-                rx_size = rx_status >> 16;
-                pkt_size = rx_size - 4;
-
-                /* process errors */
-                if ((rx_size > (MAX_ETH_FRAME_SIZE+4)) ||
-                    (!(rx_status & RxStatusOK))) {
-                        netdrv_rx_err (rx_status, dev, tp, ioaddr);
-                        return;
-                }
-
-                if (--rx_work_limit < 0)
-                        break;
-
-                /* grab a skb */
-                skb = dev_alloc_skb (pkt_size + 2);
-                if (skb) {
-                        .
-                        .
-                        netif_rx (skb);
-                        .
-                        .
-                } else {  /* OOM */
-                        /*seems very driver specific ... some just pass
-                        whatever is on the ring already. */
-                }
-
-                /* move to the next skb on the ring */
-                entry = (++tp->cur_rx) % RX_RING_SIZE;
-                received++ ;
-
-        }
-
-        /* store current ring pointer state */
-        tp->cur_rx = cur_rx;
-
-        /* Refill the Rx ring buffers if they are needed */
-        refill_rx_ring();
-        .
-        .

-5) dev->close() and dev->suspend() issues
-==========================================
-The driver writer needn't worry about this; the top net layer takes
-care of it.
-
-6) Adding new Stats to /proc 
-=============================
-In order to debug some of the new features, we introduce new stats
-that need to be collected.
-TODO: Fill this later.
-
-APPENDIX 1: discussion on using ethernet HW FC
-==============================================
-Most chips with FC only send a pause packet when they run out of Rx buffers.
-Since packets are pulled off the DMA ring by a softirq in NAPI,
-if the system is slow in grabbing them and we have a high input
-rate (faster than the system's capacity to remove packets), then theoretically
-there will only be one rx interrupt for all packets during a given packetstorm.
-Under low load, we might have a single interrupt per packet.
-FC should be programmed to apply in the case when the system cant pull out
-packets fast enough i.e send a pause only when you run out of rx buffers.
-Note FC in itself is a good solution but we have found it to not be
-much of a commodity feature (both in NICs and switches) and hence falls
-under the same category as using NIC based mitigation. Also, experiments
-indicate that it's much harder to resolve the resource allocation
-issue (aka lazy receiving that NAPI offers) and hence quantify its usefulness
-proved harder. In any case, FC works even better with NAPI but is not
-necessary.
-
-
-APPENDIX 2: the "rotting packet" race-window avoidance scheme 
-=============================================================
-
-There are two types of associations seen here
-
-1) status/int which honors level triggered IRQ
-
-If a status bit for receive or rxnobuff is set and the corresponding 
-interrupt-enable bit is not on, then no interrupts will be generated. However, 
-as soon as the "interrupt-enable" bit is unmasked, an immediate interrupt is 
-generated.  [assuming the status bit was not turned off].
-Generally the concept of level triggered IRQs in association with a status and
-interrupt-enable CSR register set is used to avoid the race.
-
-If we take the example of the tulip:
-"pending work" is indicated by the status bit(CSR5 in tulip).
-the corresponding interrupt bit (CSR7 in tulip) might be turned off (but
-the CSR5 will continue to be turned on with new packet arrivals even if
-we clear it the first time)
-Very important is the fact that if we turn on the interrupt bit on when
-status is set that an immediate irq is triggered.
- 
-If we cleared the rx ring and proclaimed there was "no more work
-to be done" and then went on to do a few other things;  then when we enable
-interrupts, there is a possibility that a new packet might sneak in during
-this phase. It helps to look at the pseudo code for the tulip poll
-routine:
-
---------------------------
-        do {
-                ACK;
-                while (ring_is_not_empty()) {
-                        work-work-work
-                        if quota is exceeded: exit, no touching irq status/mask
-                }
-                /* No packets, but new can arrive while we are doing this*/
-                CSR5 := read
-                if (CSR5 is not set) {
-                        /* If something arrives in this narrow window here,
-                        *  where the comments are ;-> irq will be generated */
-                        unmask irqs;
-                        exit poll;
-                }
-        } while (rx_status_is_set);
-------------------------
-
-CSR5 bit of interest is only the rx status. 
-If you look at the last if statement: 
-you just finished grabbing all the packets from the rx ring .. you check if
-status bit says there are more packets just in ... it says none; you then
-enable rx interrupts again; if a new packet just came in during this check,
-we are counting that CSR5 will be set in that small window of opportunity
-and that by re-enabling interrupts, we would actually trigger an interrupt
-to register the new packet for processing.
-
-[The above description nay be very verbose, if you have better wording 
-that will make this more understandable, please suggest it.]
-
-2) non-capable hardware
-
-These do not generally respect level triggered IRQs. Normally,
-irqs may be lost while being masked and the only way to leave poll is to do
-a double check for new input after netif_rx_complete() is invoked
-and re-enable polling (after seeing this new input).
-
-Sample code:
-
----------
-        .
-        .
-restart_poll:
-        while (ring_is_not_empty()) {
-                work-work-work
-                if quota is exceeded: exit, not touching irq status/mask
-        }
-        .
-        .
-        .
-        enable_rx_interrupts()
-        netif_rx_complete(dev);
-        if (ring_has_new_packet() && netif_rx_reschedule(dev, received)) {
-                disable_rx_and_rxnobufs()
-                goto restart_poll
-        } while (rx_status_is_set);
----------
-                
-Basically netif_rx_complete() removes us from the poll list, but because a
-new packet which will never be caught due to the possibility of a race
-might come in, we attempt to re-add ourselves to the poll list. 
-
-
-
-
-APPENDIX 3: Scheduling issues.
-==============================
-As seen NAPI moves processing to softirq level. Linux uses the ksoftirqd as the 
-general solution to schedule softirq's to run before next interrupt and by putting 
-them under scheduler control. Also this prevents consecutive softirq's from 
-monopolize the CPU. This also have the effect that the priority of ksoftirq needs 
-to be considered when running very CPU-intensive applications and networking to
-get the proper balance of softirq/user balance. Increasing ksoftirq priority to 0 
-(eventually more) is reported cure problems with low network performance at high 
-CPU load.
-
-Most used processes in a GIGE router:
-USER       PID %CPU %MEM  SIZE   RSS TTY STAT START   TIME COMMAND
-root         3  0.2  0.0     0     0  ?  RWN Aug 15 602:00 (ksoftirqd_CPU0)

 following format:

+It also supports logging to multiple remote agents by specifying
+parameters for the multiple agents separated by semicolons and the
+complete string enclosed in "quotes", thusly:
+
+ modprobe netconsole netconsole="@/,@10.0.0.2/;@/eth1,6892@10.0.0.3/"
+
 Built-in netconsole starts immediately after the TCP stack is
 initialized and attempts to bring up the supplied dev at the supplied
 address.
 
 The remote host can run either 'netcat -u -l -p <port>' or syslogd.
 
+Dynamic reconfiguration:
+========================
+
+Dynamic reconfigurability is a useful addition to netconsole that enables
+remote logging targets to be dynamically added, removed, or have their
+parameters reconfigured at runtime from a configfs-based userspace interface.
+[ Note that the parameters of netconsole targets that were specified/created
+from the boot/module option are not exposed via this interface, and hence
+cannot be modified dynamically. ]
+
+To include this feature, select CONFIG_NETCONSOLE_DYNAMIC when building the
+netconsole module (or kernel, if netconsole is built-in).
+
+Some examples follow (where configfs is mounted at the /sys/kernel/config
+mountpoint).
+
+To add a remote logging target (target names can be arbitrary):
+
+ cd /sys/kernel/config/netconsole/
+ mkdir target1
+
+Note that newly created targets have default parameter values (as mentioned
+above) and are disabled by default -- they must first be enabled by writing
+"1" to the "enabled" attribute (usually after setting parameters accordingly)
+as described below.
+
+To remove a target:
+
+ rmdir /sys/kernel/config/netconsole/othertarget/
+
+The interface exposes these parameters of a netconsole target to userspace:
+
+        enabled         Is this target currently enabled?       (read-write)
+        dev_name        Local network interface name            (read-write)
+        local_port      Source UDP port to use                  (read-write)
+        remote_port     Remote agent's UDP port                 (read-write)
+        local_ip        Source IP address to use                (read-write)
+        remote_ip       Remote agent's IP address               (read-write)
+        local_mac       Local interface's MAC address           (read-only)
+        remote_mac      Remote agent's MAC address              (read-write)
+
+The "enabled" attribute is also used to control whether the parameters of
+a target can be updated or not -- you can modify the parameters of only
+disabled targets (i.e. if "enabled" is 0).
+
+To update a target's parameters:
+
+ cat enabled                            # check if enabled is 1
+ echo 0 > enabled                       # disable the target (if required)
+ echo eth2 > dev_name                   # set local interface
+ echo 10.0.0.4 > remote_ip              # update some parameter
+ echo cb:a9:87:65:43:21 > remote_mac    # update more parameters
+ echo 1 > enabled                       # enable target again
+
+You can also update the local interface dynamically. This is especially
+useful if you want to use interfaces that have newly come up (and may not
+have existed when netconsole was loaded / initialized).
+
+Miscellaneous notes:
+====================
+
 WARNING: the default target ethernet setting uses the broadcast
 ethernet address to send packets, which can cause increased load on
 other systems on the same ethernet segment.
 
+TIP: some LAN switches may be configured to suppress ethernet broadcasts
+so it is advised to explicitly specify the remote agents' MAC addresses
+from the config parameters passed to netconsole.
+
+TIP: to find out the MAC address of, say, 10.0.0.2, you may try using:
+
+ ping -c 1 10.0.0.2 ; /sbin/arp -n | grep 10.0.0.2
+
+TIP: in case the remote logging agent is on a separate LAN subnet than
+the sender, it is suggested to try specifying the MAC address of the
+default gateway (you may use /sbin/route -n to find it out) as the
+remote MAC address instead.
+
 NOTE: the network device (eth1 in the above case) can run any kind
 of other network traffic, netconsole is not intrusive. Netconsole
 might cause slight delays in other traffic if the volume of kernel
 messages is high, but should have no other impact.
 
+NOTE: if you find that the remote logging agent is not receiving or
+printing all messages from the sender, it is likely that you have set
+the "console_loglevel" parameter (on the sender) to only send high
+priority messages to the console. You can change this at runtime using:
+
+ dmesg -n 8
+
+or by specifying "debug" on the kernel command line at boot, to send
+all kernel messages to the console. A specific value for this parameter
+can also be set using the "loglevel" kernel boot option. See the
+dmesg(8) man page and Documentation/kernel-parameters.txt for details.
+
 Netconsole was designed to be as instantaneous as possible, to
 enable the logging of even the most critical kernel bugs. It works
 from IRQ contexts as well, and does not enable interrupts while

-
-     - device_type : has to be "rom"
-     - compatible : Should specify what this flash device is compatible with.
-       Currently, this is most likely to be "direct-mapped" (which

-     - reg : Offset and length of the register set (or memory mapping) for

-     - bank-width : Width of the flash data bus in bytes. Required
-       for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
-
-    Recommended properties :
-
-     - partitions : Several pairs of 32-bit values where the first value is
-       partition's offset from the start of the device and the second one is
-       partition size in bytes with LSB used to signify a read only
-       partition (so, the partition size should always be an even number).
-     - partition-names : The list of concatenated zero terminated strings
-       representing the partition names.
-     - probe-type : The type of probe which should be done for the chip
-       (JEDEC vs CFI actually). Valid ONLY for NOR flashes.
+     - compatible : should contain the specific model of flash chip(s)
+       used, if known, followed by either "cfi-flash" or "jedec-flash"
+     - reg : Address range of the flash chip
+     - bank-width : Width (in bytes) of the flash bank.  Equal to the
+       device width times the number of interleaved chips.
+     - device-width : (optional) Width of a single flash chip.  If
+       omitted, assumed to be equal to 'bank-width'.
+     - #address-cells, #size-cells : Must be present if the flash has
+       sub-nodes representing partitions (see below).  In this case
+       both #address-cells and #size-cells must be equal to 1.
+
+    For JEDEC compatible devices, the following additional properties
+    are defined:
+
+     - vendor-id : Contains the flash chip's vendor id (1 byte).
+     - device-id : Contains the flash chip's device id (1 byte).
+
+    In addition to the information on the flash bank itself, the
+    device tree may optionally contain additional information
+    describing partitions of the flash address space.  This can be
+    used on platforms which have strong conventions about which
+    portions of the flash are used for what purposes, but which don't
+    use an on-flash partition table such as RedBoot.
+
+    Each partition is represented as a sub-node of the flash device.
+    Each node's name represents the name of the corresponding
+    partition of the flash device.

+    Flash partitions
+     - reg : The partition's offset and size within the flash bank.
+     - label : (optional) The label / name for this flash partition.
+       If omitted, the label is taken from the node name (excluding

+     - read-only : (optional) This parameter, if present, is a hint to
+       Linux that this flash partition should only be mounted
+       read-only.  This is usually used for flash partitions
+       containing early-boot firmware images or data which should not
+       be clobbered.

+   - fsl,pq1-pic
+   - fsl,cpm2-pic
+     - second interrupt cell is level/sense:
+       - 2 is falling edge
+       - 8 is active low
+
+   Example:
+
+        interrupt-controller@10c00 {
+                #interrupt-cells = <2>;
+                interrupt-controller;
+                reg = <10c00 80>;
+                compatible = "mpc8272-pic", "fsl,cpm2-pic";
+        };
+
+   vii) USB (Universal Serial Bus Controller)
+
+   Properties:
+   - compatible : "fsl,cpm1-usb", "fsl,cpm2-usb", "fsl,qe-usb"
+
+   Example:
+        usb@11bc0 {
+                #address-cells = <1>;
+                #size-cells = <0>;
+                compatible = "fsl,cpm2-usb";
+                reg = <11b60 18 8b00 100>;
+                interrupts = <b 8>;
+                interrupt-parent = <&PIC>;
+                fsl,cpm-command = <2e600000>;
+        };
+
+   viii) Multi-User RAM (MURAM)
+
+   The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+   Ranges must be set up subject to the following restrictions:
+
+   - Children's reg nodes must be offsets from the start of all muram, even
+     if the user-data area does not begin at zero.
+   - If multiple range entries are used, the difference between the parent
+     address and the child address must be the same in all, so that a single
+     mapping can cover them all while maintaining the ability to determine
+     CPM-side offsets with pointer subtraction.  It is recommended that
+     multiple range entries not be used.
+   - A child address of zero must be translatable, even if no reg resources
+     contain it.
+
+   A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+   indicate the portion of muram that is usable by the OS for arbitrary
+   purposes.  The data node may have an arbitrary number of reg resources,
+   all of which contribute to the allocatable muram pool.
+
+   Example, based on mpc8272:
+
+        muram@0 {
+                #address-cells = <1>;
+                #size-cells = <1>;
+                ranges = <0 0 10000>;
+
+                data@0 {
+                        compatible = "fsl,cpm-muram-data";
+                        reg = <0 2000 9800 800>;
+                };
+        };
+
+   m) Chipselect/Local Bus
+
+   Properties:
+   - name : Should be localbus
+   - #address-cells : Should be either two or three.  The first cell is the
+                      chipselect number, and the remaining cells are the
+                      offset into the chipselect.
+   - #size-cells : Either one or two, depending on how large each chipselect
+                   can be.
+   - ranges : Each range corresponds to a single chipselect, and cover
+              the entire access window as configured.
+
+   Example:
+        localbus@f0010100 {
+                compatible = "fsl,mpc8272ads-localbus",
+                             "fsl,mpc8272-localbus",
+                             "fsl,pq2-localbus";
+                #address-cells = <2>;
+                #size-cells = <1>;
+                reg = <f0010100 40>;
+
+                ranges = <0 0 fe000000 02000000
+                          1 0 f4500000 00008000>;
+
+                flash@0,0 {
+                        compatible = "jedec-flash";
+                        reg = <0 0 2000000>;
+                        bank-width = <4>;
+                        device-width = <1>;
+                };
+
+                board-control@1,0 {
+                        reg = <1 0 20>;
+                        compatible = "fsl,mpc8272ads-bcsr";
+                };
+        };
+
+
+    n) 4xx/Axon EMAC ethernet nodes
+
+    The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+    the Axon bridge.  To operate this needs to interact with a ths
+    special McMAL DMA controller, and sometimes an RGMII or ZMII
+    interface.  In addition to the nodes and properties described
+    below, the node for the OPB bus on which the EMAC sits must have a
+    correct clock-frequency property.

+rfkill - RF switch subsystem support
+====================================
+
+1 Implementation details
+2 Driver support
+3 Userspace support
+
+===============================================================================
+1: Implementation details
+
+The rfkill switch subsystem offers support for keys often found on laptops
+to enable wireless devices like WiFi and Bluetooth.
+
+This is done by providing the user 3 possibilities:
+ 1 - The rfkill system handles all events; userspace is not aware of events.
+ 2 - The rfkill system handles all events; userspace is informed about the events.
+ 3 - The rfkill system does not handle events; userspace handles all events.
+
+The buttons to enable and disable the wireless radios are important in
+situations where the user is for example using his laptop on a location where
+wireless radios _must_ be disabled (e.g. airplanes).
+Because of this requirement, userspace support for the keys should not be
+made mandatory. Because userspace might want to perform some additional smarter
+tasks when the key is pressed, rfkill still provides userspace the possibility
+to take over the task to handle the key events.
+
+The system inside the kernel has been split into 2 separate sections:
+        1 - RFKILL
+        2 - RFKILL_INPUT
+
+The first option enables rfkill support and will make sure userspace will
+be notified of any events through the input device. It also creates several
+sysfs entries which can be used by userspace. See section "Userspace support".
+
+The second option provides an rfkill input handler. This handler will
+listen to all rfkill key events and will toggle the radio accordingly.
+With this option enabled userspace could either do nothing or simply
+perform monitoring tasks.
+
+====================================
+2: Driver support
+
+To build a driver with rfkill subsystem support, the driver should
+depend on the Kconfig symbol RFKILL; it should _not_ depend on
+RKFILL_INPUT.
+
+Unless key events trigger an interrupt to which the driver listens, polling
+will be required to determine the key state changes. For this the input
+layer providers the input-polldev handler.
+
+A driver should implement a few steps to correctly make use of the
+rfkill subsystem. First for non-polling drivers:
+
+        - rfkill_allocate()
+        - input_allocate_device()
+        - rfkill_register()
+        - input_register_device()
+
+For polling drivers:
+
+        - rfkill_allocate()
+        - input_allocate_polled_device()
+        - rfkill_register()
+        - input_register_polled_device()
+
+When a key event has been detected, the correct event should be
+sent over the input device which has been registered by the driver.
+
+====================================
+3: Userspace support
+
+For each key an input device will be created which will send out the correct
+key event when the rfkill key has been pressed.
+
+The following sysfs entries will be created:
+
+        name: Name assigned by driver to this key (interface or driver name).
+        type: Name of the key type ("wlan", "bluetooth", etc).
+        state: Current state of the key. 1: On, 0: Off.
+        claim: 1: Userspace handles events, 0: Kernel handles events
+
+Both the "state" and "claim" entries are also writable. For the "state" entry
+this means that when 1 or 0 is written all radios, not yet in the requested
+state, will be will be toggled accordingly.
+For the "claim" entry writing 1 to it means that the kernel no longer handles
+key events even though RFKILL_INPUT input was enabled. When "claim" has been
+set to 0, userspace should make sure that it listens for the input events or
+check the sysfs "state" entry regularly to correctly perform the required
+tasks when the rkfill key is pressed.

+
+Authorizing (or not) your USB devices to connect to the system
+
+(C) 2007 Inaky Perez-Gonzalez <inaky@linux.intel.com> Intel Corporation
+
+This feature allows you to control if a USB device can be used (or
+not) in a system. This feature will allow you to implement a lock-down
+of USB devices, fully controlled by user space.
+
+As of now, when a USB device is connected it is configured and
+it's interfaces inmediately made available to the users. With this
+modification, only if root authorizes the device to be configured will
+then it be possible to use it.
+
+Usage:
+
+Authorize a device to connect:
+
+$ echo 1 > /sys/usb/devices/DEVICE/authorized
+
+Deauthorize a device:
+
+$ echo 0 > /sys/usb/devices/DEVICE/authorized
+
+Set new devices connected to hostX to be deauthorized by default (ie:
+lock down):
+
+$ echo 0 > /sys/bus/devices/usbX/authorized_default
+
+Remove the lock down:
+
+$ echo 1 > /sys/bus/devices/usbX/authorized_default
+
+By default, Wired USB devices are authorized by default to
+connect. Wireless USB hosts deauthorize by default all new connected
+devices (this is so because we need to do an authentication phase
+before authorizing).
+
+
+Example system lockdown (lame)
+-----------------------
+
+Imagine you want to implement a lockdown so only devices of type XYZ
+can be connected (for example, it is a kiosk machine with a visible
+USB port):
+
+boot up
+rc.local ->
+
+ for host in /sys/bus/devices/usb*
+ do
+    echo 0 > $host/authorized_default
+ done
+
+Hookup an script to udev, for new USB devices
+
+ if device_is_my_type $DEV
+ then
+   echo 1 > $device_path/authorized
+ done
+
+
+Now, device_is_my_type() is where the juice for a lockdown is. Just
+checking if the class, type and protocol match something is the worse
+security verification you can make (or the best, for someone willing
+to break it). If you need something secure, use crypto and Certificate
+Authentication or stuff like that. Something simple for an storage key
+could be:
+
+function device_is_my_type()
+{
+   echo 1 > authorized          # temporarily authorize it
+                                # FIXME: make sure none can mount it
+   mount DEVICENODE /mntpoint
+   sum=$(md5sum /mntpoint/.signature)
+   if [ $sum = $(cat /etc/lockdown/keysum) ]
+   then
+        echo "We are good, connected"
+        umount /mntpoint
+        # Other stuff so others can use it
+   else
+        echo 0 > authorized
+   fi
+}
+
+
+Of course, this is lame, you'd want to do a real certificate
+verification stuff with PKI, so you don't depend on a shared secret,
+etc, but you get the idea. Anybody with access to a device gadget kit
+can fake descriptors and device info. Don't trust that. You are
+welcome.

+
+                 Alan Stern <stern@rowland.harvard.edu>
+
+                            October 5, 2007
+
+
+
+        What is Power Management?
+        -------------------------
+
+Power Management (PM) is the practice of saving energy by suspending
+parts of a computer system when they aren't being used.  While a
+component is "suspended" it is in a nonfunctional low-power state; it
+might even be turned off completely.  A suspended component can be
+"resumed" (returned to a functional full-power state) when the kernel
+needs to use it.  (There also are forms of PM in which components are
+placed in a less functional but still usable state instead of being
+suspended; an example would be reducing the CPU's clock rate.  This
+document will not discuss those other forms.)
+
+When the parts being suspended include the CPU and most of the rest of
+the system, we speak of it as a "system suspend".  When a particular
+device is turned off while the system as a whole remains running, we
+call it a "dynamic suspend" (also known as a "runtime suspend" or
+"selective suspend").  This document concentrates mostly on how
+dynamic PM is implemented in the USB subsystem, although system PM is
+covered to some extent (see Documentation/power/*.txt for more
+information about system PM).
+
+Note: Dynamic PM support for USB is present only if the kernel was
+built with CONFIG_USB_SUSPEND enabled.  System PM support is present
+only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION
+enabled.
+
+
+        What is Remote Wakeup?
+        ----------------------
+
+When a device has been suspended, it generally doesn't resume until
+the computer tells it to.  Likewise, if the entire computer has been
+suspended, it generally doesn't resume until the user tells it to, say
+by pressing a power button or opening the cover.
+
+However some devices have the capability of resuming by themselves, or
+asking the kernel to resume them, or even telling the entire computer
+to resume.  This capability goes by several names such as "Wake On
+LAN"; we will refer to it generically as "remote wakeup".  When a
+device is enabled for remote wakeup and it is suspended, it may resume
+itself (or send a request to be resumed) in response to some external
+event.  Examples include a suspended keyboard resuming when a key is
+pressed, or a suspended USB hub resuming when a device is plugged in.
+
+
+        When is a USB device idle?
+        --------------------------
+
+A device is idle whenever the kernel thinks it's not busy doing
+anything important and thus is a candidate for being suspended.  The
+exact definition depends on the device's driver; drivers are allowed
+to declare that a device isn't idle even when there's no actual
+communication taking place.  (For example, a hub isn't considered idle
+unless all the devices plugged into that hub are already suspended.)
+In addition, a device isn't considered idle so long as a program keeps
+its usbfs file open, whether or not any I/O is going on.
+
+If a USB device has no driver, its usbfs file isn't open, and it isn't
+being accessed through sysfs, then it definitely is idle.
+
+
+        Forms of dynamic PM
+        -------------------
+
+Dynamic suspends can occur in two ways: manual and automatic.
+"Manual" means that the user has told the kernel to suspend a device,
+whereas "automatic" means that the kernel has decided all by itself to
+suspend a device.  Automatic suspend is called "autosuspend" for
+short.  In general, a device won't be autosuspended unless it has been
+idle for some minimum period of time, the so-called idle-delay time.
+
+Of course, nothing the kernel does on its own initiative should
+prevent the computer or its devices from working properly.  If a
+device has been autosuspended and a program tries to use it, the
+kernel will automatically resume the device (autoresume).  For the
+same reason, an autosuspended device will usually have remote wakeup
+enabled, if the device supports remote wakeup.
+
+It is worth mentioning that many USB drivers don't support
+autosuspend.  In fact, at the time of this writing (Linux 2.6.23) the
+only drivers which do support it are the hub driver, kaweth, asix,
+usblp, usblcd, and usb-skeleton (which doesn't count).  If a
+non-supporting driver is bound to a device, the device won't be
+autosuspended.  In effect, the kernel pretends the device is never
+idle.
+
+We can categorize power management events in two broad classes:
+external and internal.  External events are those triggered by some
+agent outside the USB stack: system suspend/resume (triggered by
+userspace), manual dynamic suspend/resume (also triggered by
+userspace), and remote wakeup (triggered by the device).  Internal
+events are those triggered within the USB stack: autosuspend and
+autoresume.
+
+
+        The user interface for dynamic PM
+        ---------------------------------
+
+The user interface for controlling dynamic PM is located in the power/
+subdirectory of each USB device's sysfs directory, that is, in
+/sys/bus/usb/devices/.../power/ where "..." is the device's ID.  The
+relevant attribute files are: wakeup, level, and autosuspend.
+
+        power/wakeup
+
+                This file is empty if the device does not support
+                remote wakeup.  Otherwise the file contains either the
+                word "enabled" or the word "disabled", and you can
+                write those words to the file.  The setting determines
+                whether or not remote wakeup will be enabled when the
+                device is next suspended.  (If the setting is changed
+                while the device is suspended, the change won't take
+                effect until the following suspend.)
+
+        power/level
+
+                This file contains one of three words: "on", "auto",
+                or "suspend".  You can write those words to the file
+                to change the device's setting.
+
+                "on" means that the device should be resumed and
+                autosuspend is not allowed.  (Of course, system
+                suspends are still allowed.)
+
+                "auto" is the normal state in which the kernel is
+                allowed to autosuspend and autoresume the device.
+
+                "suspend" means that the device should remain
+                suspended, and autoresume is not allowed.  (But remote
+                wakeup may still be allowed, since it is controlled
+                separately by the power/wakeup attribute.)
+
+        power/autosuspend
+
+                This file contains an integer value, which is the
+                number of seconds the device should remain idle before
+                the kernel will autosuspend it (the idle-delay time).
+                The default is 2.  0 means to autosuspend as soon as
+                the device becomes idle, and -1 means never to
+                autosuspend.  You can write a number to the file to
+                change the autosuspend idle-delay time.
+
+Writing "-1" to power/autosuspend and writing "on" to power/level do
+essentially the same thing -- they both prevent the device from being
+autosuspended.  Yes, this is a redundancy in the API.
+
+(In 2.6.21 writing "0" to power/autosuspend would prevent the device
+from being autosuspended; the behavior was changed in 2.6.22.  The
+power/autosuspend attribute did not exist prior to 2.6.21, and the
+power/level attribute did not exist prior to 2.6.22.)
+
+
+        Changing the default idle-delay time
+        ------------------------------------
+
+The default autosuspend idle-delay time is controlled by a module
+parameter in usbcore.  You can specify the value when usbcore is
+loaded.  For example, to set it to 5 seconds instead of 2 you would
+do:
+
+        modprobe usbcore autosuspend=5
+
+Equivalently, you could add to /etc/modprobe.conf a line saying:
+
+        options usbcore autosuspend=5
+
+Some distributions load the usbcore module very early during the boot
+process, by means of a program or script running from an initramfs
+image.  To alter the parameter value you would have to rebuild that
+image.
+
+If usbcore is compiled into the kernel rather than built as a loadable
+module, you can add
+
+        usbcore.autosuspend=5
+
+to the kernel's boot command line.
+
+Finally, the parameter value can be changed while the system is
+running.  If you do:
+
+        echo 5 >/sys/module/usbcore/parameters/autosuspend
+
+then each new USB device will have its autosuspend idle-delay
+initialized to 5.  (The idle-delay values for already existing devices
+will not be affected.)
+
+Setting the initial default idle-delay to -1 will prevent any
+autosuspend of any USB device.  This is a simple alternative to
+disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
+added benefit of allowing you to enable autosuspend for selected
+devices.
+
+
+        Warnings
+        --------
+
+The USB specification states that all USB devices must support power
+management.  Nevertheless, the sad fact is that many devices do not
+support it very well.  You can suspend them all right, but when you
+try to resume them they disconnect themselves from the USB bus or
+they stop working entirely.  This seems to be especially prevalent
+among printers and scanners, but plenty of other types of device have
+the same deficiency.
+
+For this reason, by default the kernel disables autosuspend (the
+power/level attribute is initialized to "on") for all devices other
+than hubs.  Hubs, at least, appear to be reasonably well-behaved in
+this regard.
+
+(In 2.6.21 and 2.6.22 this wasn't the case.  Autosuspend was enabled
+by default for almost all USB devices.  A number of people experienced
+problems as a result.)
+
+This means that non-hub devices won't be autosuspended unless the user
+or a program explicitly enables it.  As of this writing there aren't
+any widespread programs which will do this; we hope that in the near
+future device managers such as HAL will take on this added
+responsibility.  In the meantime you can always carry out the
+necessary operations by hand or add them to a udev script.  You can
+also change the idle-delay time; 2 seconds is not the best choice for
+every device.
+
+Sometimes it turns out that even when a device does work okay with
+autosuspend there are still problems.  For example, there are
+experimental patches adding autosuspend support to the usbhid driver,
+which manages keyboards and mice, among other things.  Tests with a
+number of keyboards showed that typing on a suspended keyboard, while
+causing the keyboard to do a remote wakeup all right, would
+nonetheless frequently result in lost keystrokes.  Tests with mice
+showed that some of them would issue a remote-wakeup request in
+response to button presses but not to motion, and some in response to
+neither.
+
+The kernel will not prevent you from enabling autosuspend on devices
+that can't handle it.  It is even possible in theory to damage a
+device by suspending it at the wrong time -- for example, suspending a
+USB hard disk might cause it to spin down without parking the heads.
+(Highly unlikely, but possible.)  Take care.
+
+
+        The driver interface for Power Management
+        -----------------------------------------
+
+The requirements for a USB driver to support external power management
+are pretty modest; the driver need only define
+
+        .suspend
+        .resume
+        .reset_resume
+
+methods in its usb_driver structure, and the reset_resume method is
+optional.  The methods' jobs are quite simple:
+
+        The suspend method is called to warn the driver that the
+        device is going to be suspended.  If the driver returns a
+        negative error code, the suspend will be aborted.  Normally
+        the driver will return 0, in which case it must cancel all
+        outstanding URBs (usb_kill_urb()) and not submit any more.
+
+        The resume method is called to tell the driver that the
+        device has been resumed and the driver can return to normal
+        operation.  URBs may once more be submitted.
+
+        The reset_resume method is called to tell the driver that
+        the device has been resumed and it also has been reset.
+        The driver should redo any necessary device initialization,
+        since the device has probably lost most or all of its state
+        (although the interfaces will be in the same altsettings as
+        before the suspend).
+
+The reset_resume method is used by the USB Persist facility (see
+Documentation/usb/persist.txt) and it can also be used under certain
+circumstances when CONFIG_USB_PERSIST is not enabled.  Currently, if a
+device is reset during a resume and the driver does not have a
+reset_resume method, the driver won't receive any notification about
+the resume.  Later kernels will call the driver's disconnect method;
+2.6.23 doesn't do this.
+
+USB drivers are bound to interfaces, so their suspend and resume
+methods get called when the interfaces are suspended or resumed.  In
+principle one might want to suspend some interfaces on a device (i.e.,
+force the drivers for those interface to stop all activity) without
+suspending the other interfaces.  The USB core doesn't allow this; all
+interfaces are suspended when the device itself is suspended and all
+interfaces are resumed when the device is resumed.  It isn't possible
+to suspend or resume some but not all of a device's interfaces.  The
+closest you can come is to unbind the interfaces' drivers.
+
+
+        The driver interface for autosuspend and autoresume
+        ---------------------------------------------------
+
+To support autosuspend and autoresume, a driver should implement all
+three of the methods listed above.  In addition, a driver indicates
+that it supports autosuspend by setting the .supports_autosuspend flag
+in its usb_driver structure.  It is then responsible for informing the
+USB core whenever one of its interfaces becomes busy or idle.  The
+driver does so by calling these three functions:
+
+        int  usb_autopm_get_interface(struct usb_interface *intf);
+        void usb_autopm_put_interface(struct usb_interface *intf);
+        int  usb_autopm_set_interface(struct usb_interface *intf);
+
+The functions work by maintaining a counter in the usb_interface
+structure.  When intf->pm_usage_count is > 0 then the interface is
+deemed to be busy, and the kernel will not autosuspend the interface's
+device.  When intf->pm_usage_count is <= 0 then the interface is
+considered to be idle, and the kernel may autosuspend the device.
+
+(There is a similar pm_usage_count field in struct usb_device,
+associated with the device itself rather than any of its interfaces.
+This field is used only by the USB core.)
+
+The driver owns intf->pm_usage_count; it can modify the value however
+and whenever it likes.  A nice aspect of the usb_autopm_* routines is
+that the changes they make are protected by the usb_device structure's
+PM mutex (udev->pm_mutex); however drivers may change pm_usage_count
+without holding the mutex.
+
+        usb_autopm_get_interface() increments pm_usage_count and
+        attempts an autoresume if the new value is > 0 and the
+        device is suspended.
+
+        usb_autopm_put_interface() decrements pm_usage_count and
+        attempts an autosuspend if the new value is <= 0 and the
+        device isn't suspended.
+
+        usb_autopm_set_interface() leaves pm_usage_count alone.
+        It attempts an autoresume if the value is > 0 and the device
+        is suspended, and it attempts an autosuspend if the value is
+        <= 0 and the device isn't suspended.
+
+There also are a couple of utility routines drivers can use:
+
+        usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
+        usb_autopm_set_interface(), which will attempt an autoresume.
+
+        usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
+        usb_autopm_set_interface(), which will attempt an autosuspend.
+
+The conventional usage pattern is that a driver calls
+usb_autopm_get_interface() in its open routine and
+usb_autopm_put_interface() in its close or release routine.  But
+other patterns are possible.
+
+The autosuspend attempts mentioned above will often fail for one
+reason or another.  For example, the power/level attribute might be
+set to "on", or another interface in the same device might not be
+idle.  This is perfectly normal.  If the reason for failure was that
+the device hasn't been idle for long enough, a delayed workqueue
+routine is automatically set up to carry out the operation when the
+autosuspend idle-delay has expired.
+
+Autoresume attempts also can fail.  This will happen if power/level is
+set to "suspend" or if the device doesn't manage to resume properly.
+Unlike autosuspend, there's no delay for an autoresume.
+
+
+        Other parts of the driver interface
+        -----------------------------------
+
+Sometimes a driver needs to make sure that remote wakeup is enabled
+during autosuspend.  For example, there's not much point
+autosuspending a keyboard if the user can't cause the keyboard to do a
+remote wakeup by typing on it.  If the driver sets
+intf->needs_remote_wakeup to 1, the kernel won't autosuspend the
+device if remote wakeup isn't available or has been disabled through
+the power/wakeup attribute.  (If the device is already autosuspended,
+though, setting this flag won't cause the kernel to autoresume it.
+Normally a driver would set this flag in its probe method, at which
+time the device is guaranteed not to be autosuspended.)
+
+The usb_autopm_* routines have to run in a sleepable process context;
+they must not be called from an interrupt handler or while holding a
+spinlock.  In fact, the entire autosuspend mechanism is not well geared
+toward interrupt-driven operation.  However there is one thing a
+driver can do in an interrupt handler:
+
+        usb_mark_last_busy(struct usb_device *udev);
+
+This sets udev->last_busy to the current time.  udev->last_busy is the
+field used for idle-delay calculations; updating it will cause any
+pending autosuspend to be moved back.  The usb_autopm_* routines will
+also set the last_busy field to the current time.
+
+Calling urb_mark_last_busy() from within an URB completion handler is
+subject to races: The kernel may have just finished deciding the
+device has been idle for long enough but not yet gotten around to
+calling the driver's suspend method.  The driver would have to be
+responsible for synchronizing its suspend method with its URB
+completion handler and causing the autosuspend to fail with -EBUSY if
+an URB had completed too recently.
+
+External suspend calls should never be allowed to fail in this way,
+only autosuspend calls.  The driver can tell them apart by checking
+udev->auto_pm; this flag will be set to 1 for internal PM events
+(autosuspend or autoresume) and 0 for external PM events.
+
+Many of the ingredients in the autosuspend framework are oriented
+towards interfaces: The usb_interface structure contains the
+pm_usage_cnt field, and the usb_autopm_* routines take an interface
+pointer as their argument.  But somewhat confusingly, a few of the
+pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
+structure instead.  Drivers need to keep this straight; they can call
+interface_to_usbdev() to find the device structure for a given
+interface.
+
+
+        Locking requirements
+        --------------------
+
+All three suspend/resume methods are always called while holding the
+usb_device's PM mutex.  For external events -- but not necessarily for
+autosuspend or autoresume -- the device semaphore (udev->dev.sem) will
+also be held.  This implies that external suspend/resume events are
+mutually exclusive with calls to probe, disconnect, pre_reset, and
+post_reset; the USB core guarantees that this is true of internal
+suspend/resume events as well.
+
+If a driver wants to block all suspend/resume calls during some
+critical section, it can simply acquire udev->pm_mutex.
+Alternatively, if the critical section might call some of the
+usb_autopm_* routines, the driver can avoid deadlock by doing:
+
+        down(&udev->dev.sem);
+        rc = usb_autopm_get_interface(intf);
+
+and at the end of the critical section:
+
+        if (!rc)
+                usb_autopm_put_interface(intf);
+        up(&udev->dev.sem);
+
+Holding the device semaphore will block all external PM calls, and the
+usb_autopm_get_interface() will prevent any internal PM calls, even if
+it fails.  (Exercise: Why?)
+
+The rules for locking order are:
+
+        Never acquire any device semaphore while holding any PM mutex.
+
+        Never acquire udev->pm_mutex while holding the PM mutex for
+        a device that isn't a descendant of udev.
+
+In other words, PM mutexes should only be acquired going up the device
+tree, and they should be acquired only after locking all the device
+semaphores you need to hold.  These rules don't matter to drivers very
+much; they usually affect just the USB core.
+
+Still, drivers do need to be careful.  For example, many drivers use a
+private mutex to synchronize their normal I/O activities with their
+disconnect method.  Now if the driver supports autosuspend then it
+must call usb_autopm_put_interface() from somewhere -- maybe from its
+close method.  It should make the call while holding the private mutex,
+since a driver shouldn't call any of the usb_autopm_* functions for an
+interface from which it has been unbound.
+
+But the usb_autpm_* routines always acquire the device's PM mutex, and
+consequently the locking order has to be: private mutex first, PM
+mutex second.  Since the suspend method is always called with the PM
+mutex held, it mustn't try to acquire the private mutex.  It has to
+synchronize with the driver's I/O activities in some other way.
+
+
+        Interaction between dynamic PM and system PM
+        --------------------------------------------
+
+Dynamic power management and system power management can interact in
+a couple of ways.
+
+Firstly, a device may already be manually suspended or autosuspended
+when a system suspend occurs.  Since system suspends are supposed to
+be as transparent as possible, the device should remain suspended
+following the system resume.  The 2.6.23 kernel obeys this principle
+for manually suspended devices but not for autosuspended devices; they
+do get resumed when the system wakes up.  (Presumably they will be
+autosuspended again after their idle-delay time expires.)  In later
+kernels this behavior will be fixed.
+
+(There is an exception.  If a device would undergo a reset-resume
+instead of a normal resume, and the device is enabled for remote
+wakeup, then the reset-resume takes place even if the device was
+already suspended when the system suspend began.  The justification is
+that a reset-resume is a kind of remote-wakeup event.  Or to put it
+another way, a device which needs a reset won't be able to generate
+normal remote-wakeup signals, so it ought to be resumed immediately.)
+
+Secondly, a dynamic power-management event may occur as a system
+suspend is underway.  The window for this is short, since system
+suspends don't take long (a few seconds usually), but it can happen.
+For example, a suspended device may send a remote-wakeup signal while
+the system is suspending.  The remote wakeup may succeed, which would
+cause the system suspend to abort.  If the remote wakeup doesn't
+succeed, it may still remain active and thus cause the system to
+resume as soon as the system suspend is complete.  Or the remote
+wakeup may fail and get lost.  Which outcome occurs depends on timing
+and on the hardware and firmware design.
+
+More interestingly, a device might undergo a manual resume or
+autoresume during system suspend.  With current kernels this shouldn't
+happen, because manual resumes must be initiated by userspace and
+autoresumes happen in response to I/O requests, but all user processes
+and I/O should be quiescent during a system suspend -- thanks to the
+freezer.  However there are plans to do away with the freezer, which
+would mean these things would become possible.  If and when this comes
+about, the USB core will carefully arrange matters so that either type
+of resume will block until the entire system has resumed.
