 0. Structure of PCI drivers
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
-There exist two kinds of PCI drivers: new-style ones (which leave most of
-probing for devices to the PCI layer and support online insertion and removal
-of devices [thus supporting PCI, hot-pluggable PCI and CardBus in a single
-driver]) and old-style ones which just do all the probing themselves. Unless
-you have a very good reason to do so, please don't use the old way of probing
-in any new code. After the driver finds the devices it wishes to operate
-on (either the old or the new way), it needs to perform the following steps:
+PCI drivers "discover" PCI devices in a system via pci_register_driver().
+Actually, it's the other way around. When the PCI generic code discovers
+a new device, the driver with a matching "description" will be notified.
+Details on this below.
+
+pci_register_driver() leaves most of the probing for devices to
+the PCI layer and supports online insertion/removal of devices [thus
+supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver].
+pci_register_driver() call requires passing in a table of function
+pointers and thus dictates the high level structure of a driver.
+
+Once the driver knows about a PCI device and takes ownership, the
+driver generally needs to perform the following initialization:
 
         Enable the device
-        Access device configuration space
-        Discover resources (addresses and IRQ numbers) provided by the device
-        Allocate these resources
-        Communicate with the device
+        Request MMIO/IOP resources
+        Set the DMA mask size (for both coherent and streaming DMA)
+        Allocate and initialize shared control data (pci_allocate_coherent())
+        Access device configuration space (if needed)
+        Register IRQ handler (request_irq())
+        Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+        Enable DMA/processing engines
+
+When done using the device, and perhaps the module needs to be unloaded,
+the driver needs to take the follow steps:
+        Disable the device from generating IRQs
+        Release the IRQ (free_irq())
+        Stop all DMA activity
+        Release DMA buffers (both streaming and coherent)
+        Unregister from other subsystems (e.g. scsi or netdev)
+        Release MMIO/IOP resources
         Disable the device
 
-Most of these topics are covered by the following sections, for the rest
-look at <linux/pci.h>, it's hopefully well commented.
+Most of these topics are covered in the following sections.

+Once added, the driver probe routine will be invoked for any unclaimed

+1.1 "Attributes" for driver functions/data
+
 Please mark the initialization and cleanup functions where appropriate
 (the corresponding macros are defined in <linux/init.h>):
 
         __init          Initialization code. Thrown away after the driver
                         initializes.
         __exit          Exit code. Ignored for non-modular drivers.
-        __devinit       Device initialization code. Identical to __init if
-                        the kernel is not compiled with CONFIG_HOTPLUG, normal
-                        function otherwise.

+                        with CONFIG_HOTPLUG, normal function otherwise.
         __devexit       The same for __exit.
 
-Tips:
-        The module_init()/module_exit() functions (and all initialization
-        functions called only from these) should be marked __init/exit.
-        The struct pci_driver shouldn't be marked with any of these tags.
-        The ID table array should be marked __devinitdata.
-        The probe() and remove() functions (and all initialization
-        functions called only from these) should be marked __devinit/exit.
-        If you are sure the driver is not a hotplug driver then use only 
-        __init/exit __initdata/exitdata.
+Tips on when/where to use the above attributes:
+        o The module_init()/module_exit() functions (and all
+          initialization functions called _only_ from these)
+          should be marked __init/__exit.
 
-        Pointers to functions marked as __devexit must be created using
-        __devexit_p(function_name).  That will generate the function
-        name or NULL if the __devexit function will be discarded.
+        o Do not mark the struct pci_driver.
 
+        o The ID table array should be marked __devinitdata.

+2. How to find PCI devices manually
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+PCI drivers should have a really good reason for not using the
+pci_register_driver() interface to search for PCI devices.
+The main reason PCI devices are controlled by multiple drivers
+is because one PCI device implements several different HW services.

+3. Device Initialization Steps
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As noted in the introduction, most PCI drivers need the following steps
+for device initialization:
 
-   If you want to use the PCI Memory-Write-Invalidate transaction,
+        Enable the device
+        Request MMIO/IOP resources
+        Set the DMA mask size (for both coherent and streaming DMA)
+        Allocate and initialize shared control data (pci_allocate_coherent())
+        Access device configuration space (if needed)
+        Register IRQ handler (request_irq())
+        Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+        Enable DMA/processing engines.
+
+The driver can access PCI config space registers at any time.
+(Well, almost. When running BIST, config space can go away...but
+that will just result in a PCI Bus Master Abort and config reads
+will return garbage).
+
+
+3.1 Enable the PCI device
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Before touching any device registers, the driver needs to enable
+the PCI device by calling pci_enable_device(). This will:
+        o wake up the device if it was in suspended state,
+        o allocate I/O and memory regions of the device (if BIOS did not),
+        o allocate an IRQ (if BIOS did not).
+
+NOTE: pci_enable_device() can fail! Check the return value.
+NOTE2: Also see pci_enable_device_bars() below. Drivers can
+    attempt to enable only a subset of BARs they need.
+
+[ OS BUG: we don't check resource allocations before enabling those
+  resources. The sequence would make more sense if we called
+  pci_request_resources() before calling pci_enable_device().
+  Currently, the device drivers can't detect the bug when when two
+  devices have been allocated the same range. This is not a common
+  problem and unlikely to get fixed soon.
+
+  This has been discussed before but not changed as of 2.6.19:
+        http://lkml.org/lkml/2006/3/2/194
+]
+
+pci_set_master() will enable DMA by setting the bus master bit
+in the PCI_COMMAND register. It also fixes the latency timer value if
+it's set to something bogus by the BIOS.
+
+If the PCI device can use the PCI Memory-Write-Invalidate transaction,
 call pci_set_mwi().  This enables the PCI_COMMAND bit for Mem-Wr-Inval
 and also ensures that the cache line size register is set correctly.
-Make sure to check the return value of pci_set_mwi(), not all architectures
-may support Memory-Write-Invalidate.
+Check the return value of pci_set_mwi() as not all architectures
+or chip-sets may support Memory-Write-Invalidate.
+
+
+3.2 Request MMIO/IOP resources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Memory (MMIO), and I/O port addresses should NOT be read directly
+from the PCI device config space. Use the values in the pci_dev structure
+as the PCI "bus address" might have been remapped to a "host physical"
+address by the arch/chip-set specific kernel support.
 
-   If your driver decides to stop using the device (e.g., there was an
-error while setting it up or the driver module is being unloaded), it
-should call pci_disable_device() to deallocate any IRQ resources, disable
-PCI bus-mastering, etc.  You should not do anything with the device after
+See Documentation/IO-mapping.txt for how to access device registers
+or device memory.
+
+The device driver needs to call pci_request_region() to verify
+no other device is already using the same address resource.
+Conversely, drivers should call pci_release_region() AFTER
 calling pci_disable_device().
+The idea is to prevent two devices colliding on the same address range.
+
+[ See OS BUG comment above. Currently (2.6.19), The driver can only
+  determine MMIO and IO Port resource availability _after_ calling
+  pci_enable_device(). ]
+
+Generic flavors of pci_request_region() are request_mem_region()
+(for MMIO ranges) and request_region() (for IO Port ranges).
+Use these for address resources that are not described by "normal" PCI
+BARs.
+
+Also see pci_request_selected_regions() below.
+
+
+3.3 Set the DMA mask size
+~~~~~~~~~~~~~~~~~~~~~~~~~
+[ If anything below doesn't make sense, please refer to
+  Documentation/DMA-API.txt. This section is just a reminder that
+  drivers need to indicate DMA capabilities of the device and is not
+  an authoritative source for DMA interfaces. ]
+
+While all drivers should explicitly indicate the DMA capability
+(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
+32-bit bus master capability for streaming data need the driver
+to "register" this capability by calling pci_set_dma_mask() with
+appropriate parameters.  In general this allows more efficient DMA
+on systems where System RAM exists above 4G _physical_ address.
+
+Drivers for all PCI-X and PCIe compliant devices must call
+pci_set_dma_mask() as they are 64-bit DMA devices.
+
+Similarly, drivers must also "register" this capability if the device
+can directly address "consistent memory" in System RAM above 4G physical
+address by calling pci_set_consistent_dma_mask().
+Again, this includes drivers for all PCI-X and PCIe compliant devices.
+Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are
+64-bit DMA capable for payload ("streaming") data but not control
+("consistent") data.
+
+
+3.4 Setup shared control data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared)
+memory.  See Documentation/DMA-API.txt for a full description of
+the DMA APIs. This section is just a reminder that it needs to be done
+before enabling DMA on the device.
+
+
+3.5 Initialize device registers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers will need specific "capability" fields programmed
+or other "vendor specific" register initialized or reset.
+E.g. clearing pending interrupts.
+
+
+3.6 Register IRQ handler
+~~~~~~~~~~~~~~~~~~~~~~~~
+While calling request_irq() is the the last step described here,
+this is often just another intermediate step to initialize a device.
+This step can often be deferred until the device is opened for use.
+
+All interrupt handlers for IRQ lines should be registered with IRQF_SHARED
+and use the devid to map IRQs to devices (remember that all PCI IRQ lines
+can be shared).
+
+request_irq() will associate an interrupt handler and device handle
+with an interrupt number. Historically interrupt numbers represent
+IRQ lines which run from the PCI device to the Interrupt controller.
+With MSI and MSI-X (more below) the interrupt number is a CPU "vector".
+
+request_irq() also enables the interrupt. Make sure the device is
+quiesced and does not have any interrupts pending before registering
+the interrupt handler.
+
+MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts"
+which deliver interrupts to the CPU via a DMA write to a Local APIC.
+The fundamental difference between MSI and MSI-X is how multiple
+"vectors" get allocated. MSI requires contiguous blocks of vectors
+while MSI-X can allocate several individual ones.
+
+MSI capability can be enabled by calling pci_enable_msi() or
+pci_enable_msix() before calling request_irq(). This causes
+the PCI support to program CPU vector data into the PCI device
+capability registers.
+
+If your PCI device supports both, try to enable MSI-X first.
+Only one can be enabled at a time.  Many architectures, chip-sets,
+or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix
+will fail. This is important to note since many drivers have
+two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs.
+They choose which handler to register with request_irq() based on the
+return value from pci_enable_msi/msix().
+
+There are (at least) two really good reasons for using MSI:
+1) MSI is an exclusive interrupt vector by definition.
+   This means the interrupt handler doesn't have to verify
+   its device caused the interrupt.
+
+2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed
+   to be visible to the host CPU(s) when the MSI is delivered. This
+   is important for both data coherency and avoiding stale control data.
+   This guarantee allows the driver to omit MMIO reads to flush
+   the DMA stream.
+
+See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples
+of MSI/MSI-X usage.
+
+
+
+4. PCI device shutdown
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When a PCI device driver is being unloaded, most of the following
+steps need to be performed:
+
+        Disable the device from generating IRQs
+        Release the IRQ (free_irq())
+        Stop all DMA activity
+        Release DMA buffers (both streaming and consistent)
+        Unregister from other subsystems (e.g. scsi or netdev)
+        Disable device from responding to MMIO/IO Port addresses
+        Release MMIO/IO Port resource(s)
+
+
+4.1 Stop IRQs on the device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+How to do this is chip/device specific. If it's not done, it opens
+the possibility of a "screaming interrupt" if (and only if)
+the IRQ is shared with another device.
+
+When the shared IRQ handler is "unhooked", the remaining devices
+using the same IRQ line will still need the IRQ enabled. Thus if the
+"unhooked" device asserts IRQ line, the system will respond assuming
+it was one of the remaining devices asserted the IRQ line. Since none
+of the other devices will handle the IRQ, the system will "hang" until
+it decides the IRQ isn't going to get handled and masks the IRQ (100,000
+iterations later). Once the shared IRQ is masked, the remaining devices
+will stop functioning properly. Not a nice situation.
+
+This is another reason to use MSI or MSI-X if it's available.
+MSI and MSI-X are defined to be exclusive interrupts and thus
+are not susceptible to the "screaming interrupt" problem.
+
+
+4.2 Release the IRQ
+~~~~~~~~~~~~~~~~~~~
+Once the device is quiesced (no more IRQs), one can call free_irq().
+This function will return control once any pending IRQs are handled,
+"unhook" the drivers IRQ handler from that IRQ, and finally release
+the IRQ if no one else is using it.
+
+
+4.3 Stop all DMA activity
+~~~~~~~~~~~~~~~~~~~~~~~~~
+It's extremely important to stop all DMA operations BEFORE attempting
+to deallocate DMA control data. Failure to do so can result in memory
+corruption, hangs, and on some chip-sets a hard crash.
 
-4. How to access PCI config space
+Stopping DMA after stopping the IRQs can avoid races where the
+IRQ handler might restart DMA engines.
+
+While this step sounds obvious and trivial, several "mature" drivers
+didn't get this step right in the past.
+
+
+4.4 Release DMA buffers
+~~~~~~~~~~~~~~~~~~~~~~~
+Once DMA is stopped, clean up streaming DMA first.
+I.e. unmap data buffers and return buffers to "upstream"
+owners if there is one.
+
+Then clean up "consistent" buffers which contain the control data.
+
+See Documentation/DMA-API.txt for details on unmapping interfaces.
+
+
+4.5 Unregister from other subsystems
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most low level PCI device drivers support some other subsystem
+like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your
+driver isn't losing resources from that other subsystem.
+If this happens, typically the symptom is an Oops (panic) when
+the subsystem attempts to call into a driver that has been unloaded.
+
+
+4.6 Disable Device from responding to MMIO/IO Port addresses
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+io_unmap() MMIO or IO Port resources and then call pci_disable_device().
+This is the symmetric opposite of pci_enable_device().
+Do not access device registers after calling pci_disable_device().
+
+
+4.7 Release MMIO/IO Port Resource(s)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Call pci_release_region() to mark the MMIO or IO Port range as available.
+Failure to do so usually results in the inability to reload the driver.

+
+
+The alternative is the traditional PCI device driver that walks PCI
+device lists. This is still possible but discouraged.
+
+
+
+10. pci_enable_device_bars() and Legacy I/O Port space
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Large servers may not be able to provide I/O port resources to all PCI
+devices. I/O Port space is only 64KB on Intel Architecture[1] and is
+likely also fragmented since the I/O base register of PCI-to-PCI
+bridge will usually be aligned to a 4KB boundary[2]. On such systems,
+pci_enable_device() and pci_request_region() will fail when
+attempting to enable I/O Port regions that don't have I/O Port
+resources assigned.
+
+Fortunately, many PCI devices which request I/O Port resources also
+provide access to the same registers via MMIO BARs. These devices can
+be handled without using I/O port space and the drivers typically
+offer a CONFIG_ option to only use MMIO regions
+(e.g. CONFIG_TULIP_MMIO). PCI devices typically provide I/O port
+interface for legacy OSes and will work when I/O port resources are not
+assigned. The "PCI Local Bus Specification Revision 3.0" discusses
+this on p.44, "IMPLEMENTATION NOTE".
+
+If your PCI device driver doesn't need I/O port resources assigned to
+I/O Port BARs, you should use pci_enable_device_bars() instead of
+pci_enable_device() in order not to enable I/O port regions for the
+corresponding devices. In addition, you should use
+pci_request_selected_regions() and pci_release_selected_regions()
+instead of pci_request_regions()/pci_release_regions() in order not to
+request/release I/O port regions for the corresponding devices.
+
+[1] Some systems support 64KB I/O port space per PCI segment.
+[2] Some PCI-to-PCI bridges support optional 1KB aligned I/O base.
+
+
+
+11. MMIO Space and "Write Posting"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Converting a driver from using I/O Port space to using MMIO space
+often requires some additional changes. Specifically, "write posting"
+needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2)
+already do this. I/O Port space guarantees write transactions reach the PCI
+device before the CPU can continue. Writes to MMIO space allow the CPU
+to continue before the transaction reaches the PCI device. HW weenies
+call this "Write Posting" because the write completion is "posted" to
+the CPU before the transaction has reached its destination.
+
+Thus, timing sensitive code should add readl() where the CPU is
+expected to wait before doing other work.  The classic "bit banging"
+sequence works fine for I/O Port space:
+
+       for (i = 8; --i; val >>= 1) {
+               outb(val & 1, ioport_reg);      /* write bit */
+               udelay(10);
+       }
+
+The same sequence for MMIO space should be:
+
+       for (i = 8; --i; val >>= 1) {
+               writeb(val & 1, mmio_reg);      /* write bit */
+               readb(safe_mmio_reg);           /* flush posted write */
+               udelay(10);
+       }
+
+It is important that "safe_mmio_reg" not have any side effects that
+interferes with the correct operation of the device.
+
+Another case to watch out for is when resetting a PCI device. Use PCI
+Configuration space reads to flush the writel(). This will gracefully
+handle the PCI master abort on all platforms if the PCI device is
+expected to not respond to a readl().  Most x86 platforms will allow
+MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage
+(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail").
