i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers
should use set this value in terms of HZ.
Ultimately I think this field should be discarded in favor of
i2c_adapter.timeout, but that's left for a future patch.

The unit in which user-space can set the bus timeout value is jiffies
for historical reasons (back when HZ was always 100.) This is however
not good because user-space doesn't know how long a jiffy lasts. The
timeout value should instead be set in a fixed time unit. Given the
original value of HZ, this unit should be 10 ms, for compatibility.

With a postfix decrement these timeouts reach -1 rather than 0, but
after the loop it is tested whether they have become 0.
As pointed out by Jean Delvare, the condition we are waiting for should
also be tested before the timeout. With the current order, you could
exit with a timeout error while the job is actually done.

error
I found that the function fdtv_frontend_init in the file firedtv-fe.c was
missing a case for FIREDTV_DVB_S2 which resulted in "frequency limits
undefined" errors in syslog.
Signed-off-by: Beat Michel Liechti <bml303@gmail.com>
Change by Stefan R: combine it with case case FIREDTV_DVB_S as
originally suggested by Beat Michel. This enables FE_CAN_FEC_AUTO also
for FireDTV-S2 devices which is possible as long as only DVB-S channels
are used. FE_CAN_FEC_AUTO would be wrong for DVB-S2 channels, but those
cannot be used yet since the driver is not yet converted to S2API.

firedtv: reinstate debug logging option
Henrik Kurelid tells me that FCP debug logging (which I removed during
cleanups) is still useful when working on driver issues together with
end users. So bring it back in an updated form with only 60% of the
original code footprint.
Logging can be enabled with
# echo -1 > /sys/module/firedtv/parameters/debug
1 instead of -1 enables only FCP header logging,
2 instead of -1 enables only hexdumps of the entire FCP frames.
0 switches logging off again.

firedtv: dvb demux: some simplifications
c->active was unnecessarily cleared twice.
Also, by marking the channel inactive before the for loop,
the loop becomes identical with fdtv_channel_collect().
Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: remove a bogus loop
This loop is unnecessary because
- only active channel[].pid's will be sent to the device,
- when a channel is activated, its pid is set to dvbdmxfeed->pid.
Perhaps the original code was there because it was initially not fully
covered by the fdtv->demux_mutex.

firedtv: dvb demux: fix mutex protection
fdtv_start_feed() accessed the channel list unsafely.

firedtv: dvb demux: fix missing braces
Original code was:
...
case DMX_TS_PES_OTHER:
//Dirty fix to keep firesat->channel pid-list up to date
for(k=0;k<16;k++){
if(firesat->channel[k].active == 0)
firesat->channel[k].pid =
dvbdmxfeed->pid;
break;
}
channel = firesat_channel_allocate(firesat);
break;
default:
...
Looks bogus in several respects. For now let's just add braces to the if
because that seems to be what the author meant.

firedtv: avc: reduce stack usage, remove two typedefs
It is safe to share a memory buffer for command frame and response frame
because the response data come in after the command frame was last used.
Even less stack would be required if only the actual required frame size
instead of the entire FCP register size was allocated.
Also, rename the defined types AVCCmdFrm and AVCRspFrm to
struct avc_command_frame and struct avc_response_frame.

Use macros/ inline functions/ standard byte order accessors to read and
write oPCR register values (big endian bitfields, on-the-wire data).
The new code may not be the ultimate optimum, but it doesn't occur in a
hot path.
This fixes the CMP code for big endian CPUs. So far I tested it only on
a little endian CPU though.
For now, include <asm/byteorder.h> instead of <linux/byteorder.h>
because drivers/ieee1394/*.h also include the former. I will fix this
in drivers/ieee1394 and firedtv later.

firedtv: register input device as child of a FireWire device
Instead of one virtual input device which exists for the whole lifetime
of the driver and receives events from all connected FireDTVs, register
one input device for each firedtv device. These input devices will show
up as children of the respective firedtv devices in the sysfs hierarchy.
However, the implementation falls short because of a bug in userspace:
Udev's path_id script gets stuck with 100% CPU utilization, maybe
because of an assumption about the maximum ieee1394 device hierarchy
depth.
To avoid this bug, we use the fw-host device instead of the proper
unit_directory device as parent of the input device.
There is hope that the port to the new firewire stack won't be inhibited
by this userspace bug because there are no fw-host devices there.

Sparse found a bug:

This reduces module size by about 1 kB.

firedtv: remove unused dual subunit code from initialization
No FireDTVs with more than one subunit exists, hence simplify the
initialization for the special case of one subunit. The driver was able
to check for more than one subunit but was broken for more than two
subunits.
While we are at it, add several missing cleanups after failure, and
include a few dynamically allocated structures diretly into struct
firesat instead of allocating them separately.

firedtv: add vendor_id and version to driver match table
Now that nodemgr was enhanced to match against the root directory's
vendor ID if there isn't one in the unit directory, use this to
prevent firedtv to be bound to wrong devices by accident.
Also add the AV/C software version ID to the match flags for
completeness; specifier ID and software only make sense as a pair.

While Module_Vendor_ID in the configuration ROM's root directory is
mandatory, there often aren't vendor IDs in unit directories. This
affects the new firedtv driver which is meant to be auto-loaded and
matched only for vendor-specific devices.
We now always copy ne->vendor_id into ud->vendor_id before we scan a
unit directory (and fill in a possibly present vendor ID from there).
This way, the root directory's vendor ID is used as fallback in the
"uevent" environment for modprobe'ing per module alias when a node was
plugged in, and in the driver match routine when protocol drivers are
bound to unit directories. It will however not be used as sysfs
attribute of a unit directory device.

These will be used by the firedtv driver. Like hpsb_node_write() they
are much better APIs for high-level drivers than hpsb_write() and its
siblings --- easier to use correctly and also terser.
Unlike hspb_node_write(), the two new functions will only be used by
one call site. Hence make them static inline instead of exported
symbols.

A compiler barrier (explicit on the read side, implicit on the write
side) is not quite enough for what has to be accomplished here. Use
hardware memory barriers on systems which need them.
(Of course a full fix of generation handling would require much more
than this. The ieee1394 core's bus generation counter had to be tied to
the controller's bus generation counter; cf. Kristian's stack. It's
just that I have other current business with the code around these
barrier()s, so why not do at least this small fix.)

input
Combination of the following changes:
Tue, 26 Aug 2008 00:17:30 +0200 (CEST)
firedtv: fix remote control input
and update the scancode-to-keycode mapping to a current model. Per
default, various media key keycodes are emitted which closely match what
is printed on the remote. Userland can modify the mapping by means of
evdev ioctls. (Not tested.)
The old scancode-to-keycode mapping is left in the driver but cannot be
modified by ioctls. This preserves status quo for old remotes.
Tue, 26 Aug 2008 00:11:28 +0200 (CEST)
firedtv: replace tasklet by workqueue job
Non-atomic context is a lot nicer to work with.
Sun, 24 Aug 2008 23:30:00 +0200 (CEST)
firedtv: move some code back to ieee1394 core
Partially reverts "ieee1394: remove unused code" of Linux 2.6.25.
Sun, 24 Aug 2008 23:29:30 +0200 (CEST)
firedtv: replace semaphore by mutex
firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
The only exception is the schedule_remotecontrol tasklet which did a
down_trylock in atomic context. This is not possible with
mutex_trylock; however the whole remote control related code is
non-functional anyway at the moment. This should be fixed eventually,
probably by turning the tasklet into a worqueue job.
Convert everything else from semaphore to mutex.
Also rewrite a few of the affected functions to unlock the mutex at a
single exit point, instead of in several branches.
Sun, 24 Aug 2008 23:28:45 +0200 (CEST)
firedtv: some header cleanups
Unify #ifndef/#define/#endif guards against multiple inclusion.
Drop extern keyword from function declarations.
Remove #include's into header files where struct declarations suffice.
Remove unused ohci1394 interface and related unused ieee1394 interfaces.
Add a few missing #include's and remove a few apparently obsolete ones.
Sort them alphabetically.
Sun, 24 Aug 2008 23:27:45 +0200 (CEST)
firedtv: nicer registration message and some initialization fixes
Print the correct name in dvb_register_adapter().
While we are at it, replace two switch cascades by one for loop, remove
a superfluous member of struct firesat and of two unused arguments of
AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init().
Tue, 26 Aug 2008 14:24:17 +0200 (CEST)
firesat: rename to firedtv
Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver
also supports DVB-C and DVB-T receivers, hence the previous project name
is too narrow now.
Not yet done: Rename source directory, files, types, variables...
Sun, 24 Aug 2008 23:26:23 +0200 (CEST)

I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.
The latest version contains the following changes:
- Implemented the new hpsb iso interface so that data can be received
from the card
- Reduced some timers for demux setup which caused scanning to timeout
- Added possibility to unload driver
- Added support for getting C/N ratio
- Added two debug parameters to the driver; ca_debug and
avc_comm_debug.
- Added CI support that works for me in kaffeine
- Started working on CI MMI support. It now supports:
o Enter menu
o Receiving MMI objects
- Added support for 64-bit platforms
- Corrected DVB-C modulations problems

This only makes sure that a DVB-S2 device is really recognized as a S2,
nothing else is added yet. It's using the string containing the model
that is stored in the configuration ROM, the older version was using

This is a one liner change to have the driver use by default the v1.4
of the i2400m firmware instead of v1.3. The v1.4 version of the
firmware has been submitted to David Woodhouse for inclusion in the
linux-firmware tree and it is already available at
http://linuxwimax.org/Download.
The reason for this change is that the 1.3 release of the user space
software and firmware has a few issues that will make it difficult to
use with currently deployed commercial networks such as Xohm and
Clearwire.
As well, the new 1.4 release of the user space software (which matches
the 1.4 firmware) has intermitent issues with the 1.3 firmware.
The 1.4 release in http://linuxwimax.org/Download has been widely
deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware
and the 1.4 user space components.
We understand it is quite late in the rc process for such a change,
but would like to ask for the change to be taken into consideration.
Alternatively, a user could always force feed a 1.4 firmware into a
driver that doesn't have this modification by:
$ cd /lib/firmware
$ mv i2400m-fw-usb-1.3.sbcf i2400m-fw-usb-1.3.real.sbcf
$ ln -sf i2400m-fw-usb-1.4.sbc i2400m-fw-usb-1.3.sbcf

mib_counters_update() also restarts the timer.
So the timer is dequeued, the stats are read and then the timer is
enqueued again. This is "okay" unless someone unloads the module.
The locking here is also broken:
mib_counters_update() grabs just a simple spinlock. The only thing the
lock is good for is to protect the timer func against other callers
namely mv643xx_eth_stop() && mv643xx_eth_get_ethtool_stats(). That means
if the spinlock is taken via the ethtool path and than the timer kicks
in then the box will lock up.

Commit f55c21fd9a92a444e55ad1ca4e4732d56661bf2e ("forcedeth: call
restore mac addr in nv_shutdown path"), which was introduced to fix
the regression tracked at
http://bugzilla.kernel.org/show_bug.cgi?id=11358 causes the
wake-on-lan mac to be reversed in the shutdown path. Apparently the
forcedeth situation is rather messy in that the mac we need to
writeback for a subsequent modprobe to work is exactly the reverse of
what is needed for proper wake-on-lan.
The following patch explains the situation in the comments and
makes the call to nv_restore_mac_addr() conditional (only called if
we are not really going for poweroff).

The problem was that object_set_to_gpu_domain would set the new write_domains
that are getting set by this batchbuffer, then the accumulated flushes required
for all the objects in preparation for this batchbuffer were posted, and the
brand new write domain would get cleared by the flush being posted. Instead,
hang on to the new (or old if we're not changing it) value and set it after
the flush is queued.
Results from this noticably included conformance test failures from reads
shortly after writes (where the new write domain had been lost and thus not
flushed and waited on), but is a suspected cause of hangs in some apps when
a write domain is lost on a buffer that gets reused for instruction or
commmand state.

change. This change should be invariant.
