The patch introduces new snd_saa7134_capsrc_set (code taken from
snd_saa7134_capsrc_put) that updates also the ALSA capture controls during
snd_card_saa7134_capture_prepare and snd_saa7134_capsrc_put.
There can be much more work done in order to unify the control of the card
(now the card's capture source is tuned/switched in saa7134-video.c too), but
I don't have enough time. This work could be a starting point, but it can be
applied as-is too (it doesn't need any further work to make it working).

There are several reasons:
- SAA7133/35 uses DDEP (DemDec Easy Programming mode), which works in 32kHz
only
- SAA7134 for TV mode uses DemDec mode (32kHz)
- Radio works in 32kHz only
- When recording 48kHz from Line1/Line2, switching of capture source to TV
means switching to 32kHz without any frequency translation

On some alsa versions, it seems that snd_pcm_substream_chip(substream)
is returning a NULL pointer. This causes an OOPS, as reported by:
https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/212271
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/212960
This patch avoids the OOPS by not letting and open() succeed.

[ALSA] Fix synchronize_irq() bugs, redundancies
free_irq() calls synchronize_irq() for you, so there is no need for
drivers to manually do the same thing (again). Thus, calls where
sync-irq immediately precedes free-irq can be simplified.
However, during this audit several bugs were noticed, where free-irq is
preceded by a "irq >= 0" check... but the sync-irq call is not covered
by the same check.
So, where sync-irq could not be eliminated completely, the missing check
was added.

Subject: Convert videobuf-dma-sg to generic DMA API
Date: Tue, 19 Feb 2008 13:40:54 +0100 (CET)
videobuf-dma-sg does not need to depend on PCI. Switch it to using generic
DMA API, convert all affected drivers, relax Kconfig restriction, improve
compile-time type checking, fix some Coding Style violations while at it.

[ALSA] Remove sound/driver.h
This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.

The saa7134 video driver starts dropping frames when used together with the
saa7134-alsa driver. Frames are dropped because when an audio event is waiting
the driver simply ignores the interrupt and passes it on to the saa7134-alsa
interrupt handler. The alsa interrupt handler in turn acknowledges all types
of events thus clearing the pending video events as well. Fix by only masking
out the audio event in the video interrupt handler and by only acknowledging
the audio event in the alsa driver.

The period handling in saa7134-alsa is broken in two ways. First, the
minimum number of periods of two does not work, because the dma is setup
two periods ahead in the irq handler. Fix the minimum to four periods.
Second, the code assumes that the number of periods is divisible by two,
which isn't always the case on ALSA. Fix by adding a constraint.

You are right. The patch below (based on your cx88 patch, but I don't
really understand it) fixes mmap support in saa7134-alsa for me.
Recording via mmap (arecord -M -f S16_LE -c 2 -r 32000 -D hw:1) didn't
work at all before, works now, tested for at least 20 minutes (but,
unfortunately, with one overrun at least 0.719 ms long).

Due to several internal API changes on kernel, kernel backward
compatibility were lost. Basically, compat.h should be the last include
for it to work properly.
This patch basically reorders kernel headers to allow backward compat to
work fine.
Also:
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files.

Sound recording doesn't work for this card because ACNI and ACPF
are not set before snd_card_saa7134_capture_prepare(). As a result
timeout occurs. These registers aren't poked because thread
never gets wake up signal. ACNI initialization is done in the
thread.
Sound is muted when capture stops. Shouldn't be because it may
be used during TV playback.

Add -include linux/version.h to the cflags. Now code can have backward
compatibility test without including compat.h first.
Linux headers included from compat.h are removed, so that code will get
the same headers when compiling in v4l-dvb as it does in the kernel.
Many drivers have compat.h moved to the end of their include list, as
this lets compat.h do things it can't do at the beginning. Such as test
of something is defined to include compat code, or to put a wrapper
around a function without changing the function's name.

The change does the following:
- At device open, it sets the recording source to the current
input instead of LINE2. So it is no longer necessary to set the
recording source with a mixer application.
- Connects the mixer volume control to the input sensitivity selection
of the analog sound inputs. This allows only one 6db step.

Kernel-sync:
This patch is required to allow compilation of the tree with kernel
2.6.19.
This is the original description of the original patch, signed by
David Howells <dhowells@redhat.com>:
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

This moves the 32 bit ioctl compatibility handlers for
Video4Linux into a new file and adds explicit calls to them
to each v4l device driver.
Unfortunately, there does not seem to be any code handling
the v4l2 ioctls, so quite often the code goes through two
separate conversions, first from 32 bit v4l to 64 bit v4l,
and from there to 64 bit v4l2. My patch does not change
that, so there is still much room for improvement.
Also, some drivers have additional ioctl numbers, for
which the conversion should be handled internally to
that driver.
