Andreas Oberritter dda06a8e46 V4L/DVB (9029): Fix deadlock in demux code
The functions dvb_dmxdev_section_callback, dvb_dmxdev_ts_callback,
dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and
dvb_dmx_swfilter_204 may be called from both interrupt and process
context. Therefore they need to be protected by spin_lock_irqsave()
instead of spin_lock().

This fixes a deadlock discovered by lockdep.

Robert Schedel 71a35fe2a3 V4L/DVB (7830): dvb_ca_en50221: Fix High CPU load in 'top' due to budget_av slot polling
This change addresses kernel bug #10459: In kernel 2.6.25 the
budget_av driver polls for an CI slot in 100ms intervals (because no
interrupt solution for budget_av cards is feasible due to HW reasons).
If no CI/CAM is connected to the DVB card, polling times out only after 250ms.
This periodic polling leads to high CPU load.

The change increases the polling interval for empty slots from 100ms to 5s.
Intervals for remaining slot states (invalid, in progress, ready) are unchanged,
as they are either temporary conditions or no timeout should occur.

Janne Grunau 78e92006f4 V4L/DVB (7538): Adds selectable adapter numbers as per module option
The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.

Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.

options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.

With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

Andreas Oberritter 4a24ce3a17 V4L/DVB (7329): add flag to allow software demux to recognize the output type
Previously, the macro DVR_FEED, which is used to recognize and filter
out duplicate packets going to the DVR device, used the TS_PAYLOAD_ONLY
flag to identify a packet's destination.

This kind of filtering was introduced by the following two changesets:

Now, that it is possible to record TS PIDs using the demux device by
setting the output type to DMX_OUT_TSDEMUX_TAP, checking TS_PAYLOAD_ONLY
is not sufficient anymore. Therefore another flag, TS_DEMUX, is added to
specify the output type of a feed.

This allows multiple clients to filter the same TS PID on a demux device
simultaneously.

Peter Hartley b01cd93789 V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resend
Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.

This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).

At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.

The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.

Rafael J. Wysocki 8314418629 Freezer: make kernel threads nonfreezable by default
Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Patrick Boettcher dea74869f3 V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
  always, before you could assign the static pointer directly, which was
  dangerous.

Andrew de Quincey d09dbf92ad V4L/DVB (3762): Add sysfs device links to dvb devices
Currently in /sys/class/dvb/dvbX.demuxY/ we have:
	dev
	uevent
With the patch, we have (for a PCI DVB device):
	dev
	device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0
	uevent
So userspace tools can (finally) work out which physical device a DVB adapter
refers to. Previously you had to kinda look through dmesg and hope that it
hadn't been dumped out of the buffer. This makes debugging a lot easier if
the system has been up for a long time!
This is done by adding an extra 'struct device *' parameter to
dvb_register_adapter(). It will work with any kind of standard
linux 'device'. Additionally, if someone has an embedded system which does
things differently, they can simply supply 'NULL' and the behaviour will be
as before - the link will simply not appear.

Herbert Xu 932ff279a4 [NET]: Add netif_tx_lock
Various drivers use xmit_lock internally to synchronise with their
transmission routines.  They do so without setting xmit_lock_owner.
This is fine as long as netpoll is not in use.

With netpoll it is possible for deadlocks to occur if xmit_lock_owner
isn't set.  This is because if a printk occurs while xmit_lock is held
and xmit_lock_owner is not set can cause netpoll to attempt to take
xmit_lock recursively.

While it is possible to resolve this by getting netpoll to use
trylock, it is suboptimal because netpoll's sole objective is to
maximise the chance of getting the printk out on the wire.  So
delaying or dropping the message is to be avoided as much as possible.

So the only alternative is to always set xmit_lock_owner.  The
following patch does this by introducing the netif_tx_lock family of
functions that take care of setting/unsetting xmit_lock_owner.

I renamed xmit_lock to _xmit_lock to indicate that it should not be
used directly.  I didn't provide irq versions of the netif_tx_lock
functions since xmit_lock is meant to be a BH-disabling lock.

This is pretty much a straight text substitution except for a small
bug fix in winbond.  It currently uses
netif_stop_queue/spin_unlock_wait to stop transmission.  This is
unsafe as an IRQ can potentially wake up the queue.  So it is safer to
use netif_tx_disable.

The hamradio bits used spin_lock_irq but it is unnecessary as
xmit_lock must never be taken in an IRQ handler.

Unfortunately, since the mutex is unlocked before the card is added to the

breaks the tda1004x at least, and causes it to fail to tune until the
budget-av module is reloaded. This patch adds an exported function to dvb_frontend
that allows a card to forcibly reinitialise a frontend. The budget-av now
does this on CAM reset, which corrects this problem.
since they do not tie the CAM reset line to the frontend reset line.

Mark Adams b3967d6c25 [PATCH] dvb: fix bug in demux that caused lost mpeg sections
Fix a bug in the software demux which causes large MPEG sections to be lost
when they follow very small sections.

The problem happens when two sections begin in the same transport packet.  The
dvb_demux code resets its buffer only before the first of these sections.
This means that when the second (or subsequent) section begins, there is up to
182 bytes of buffer space already used.  If the following section is close to
the maximum size, it currently won't fit in the (4096-byte) buffer and is
thrown away.

The fix is simply to enlarge the buffer by the size of one transport packet
and correct one usage of the SECFEED_SIZE definition where what is really
meant is the maximum size of a section.

Tim Schmielau 4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

Christoph Lameter 3e1d1d28d9 [PATCH] Cleanup patch for process freezing
1. Establish a simple API for process freezing defined in linux/include/sched.h:

   frozen(process)		Check for frozen process
   freezing(process)		Check if a process is being frozen
   freeze(process)		Tell a process to freeze (go to refrigerator)
   thaw_process(process)	Restart process
   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!
