sbc: added "cc" to the clobber list of mmx inline assembly

In the case of scale factors calculation optimizations, the inline
assembly code has instructions which update flags register, but
"cc" was not mentioned in the clobber list. When optimizing code,
gcc theoretically is allowed to do a comparison before the inline
assembly block, and a conditional branch after it which would lead
to a problem if the flags register gets clobbered. While this is
apparently not happening in practice with the current versions of
gcc, the clobber list needs to be corrected.

Regarding the other inline assembly blocks. While most likely it
is actually unnecessary based on quick review, "cc" is also added
there to the clobber list because it should have no impact on
performance in practice. It's kind of cargo cult, but relieves
us from the need to track the potential updates of flags register

virtual-sink: Fix a crash when moving the sink to a new master right after setup.

If the virtual sink is moved to a new master right after it has been created,
then the virtual sink input's memblockq can be rewound to a negative read
index. The data written prior to the move starts from index zero, so after the
rewind there's a bit of silence. If the memblockq doesn't have a silence
memchunk set, then pa_memblockq_peek() will return zero in such case, and the
returned memchunk's memblock pointer will be NULL.

That scenario wasn't taken into account in the implementation of
sink_input_pop_cb. Setting a silence memchunk for the memblockq solves this
problem, because pa_memblock_peek() will now return a valid memblock if the
read index happens to point to a hole in the memblockq.

I believe this isn't the best possible solution, though. It doesn't really make
sense to rewind the sink input's memblockq beyond index 0 in the first place,
because now when the stream starts to play to the new master sink, there's some
unnecessary silence before the actual data starts. This is a small problem,
though, and I don't grok the rewinding system well enough to know how to fix
this issue properly.

I went through all files that call pa_memblockq_peek() to see if there are more
similar bugs. play-memblockq.c was the only one that looked to me like it might
be broken in the same way. I didn't try reproducing the bug with
play-memblockq.c, though, so I just added a FIXME comment there.

13 years agoImplement the "volume sharing" feature.
Tanu Kaskinen [Thu, 24 Feb 2011 14:16:38 +0000 (16:16 +0200)]
Implement the "volume sharing" feature.

When we have a filter sink that does some processing, currently the
benefits of the flat volume feature are not really available. That's
because if you have a music player that is connected to the filter sink,
the hardware sink doesn't have any idea of the music player's stream
volume.

This problem is solved by this "volume sharing" feature. The volume
sharing feature works so that the filter sinks that want to avoid the
previously described problem declare that they don't want to have
independent volume, but they follow the master sink volume instead.
The PA_SINK_SHARE_VOLUME_WITH_MASTER sink flag is used for that
declaration. Then the volume logic is changed so that the hardware
sink calculates its real volume using also the streams connected to the
filter sink in addition to the streams that are connected directly to
the hardware sink. Basically we're trying to create an illusion that
from volume point of view all streams are connected directly to the
hardware sink.

For that illusion to work, the volumes of the filter sinks and their
virtual streams have to be managed carefully according to a set of
rules:

If a filter sink follows the hardware sink volume, then the filter sink's
 * reference_volume always equals the hw sink's reference_volume
 * real_volume always equals the hw sink's real_volume
 * soft_volume is always 0dB (ie. no soft volume)

If a filter sink doesn't follow the hardware sink volume, then the filter
sink's
 * reference_volume can be whatever (completely independent from the hw sink)
 * real_volume always equals reference_volume
 * soft_volume always equals real_volume (and reference_volume)

If a filter sink follows the hardware sink volume, and the hardware sink
supports flat volume, then the filter sink's virtual stream's
 * volume always equals the hw sink's real_volume
 * reference_ratio is calculated normally from the stream volume and the hw
   sink's reference_volume
 * real_ratio always equals 0dB (follows from the first point)
 * soft_volume always equals volume_factor (follows from the previous point)

If a filter sink follows the hardware sink volume, and the hardware sink
doesn't support flat volume, then the filter sink's virtual stream's
 * volume is always 0dB
 * reference_ratio is always 0dB
 * real_ratio is always 0dB
 * soft_volume always equals volume_factor

If a filter sink doesn't follow the hardware sink volume, then the filter
sink's virtual stream is handled as a regular stream.

Since the volumes of the virtual streams are controlled by a set of rules,
the user is not allowed to change the virtual streams' volumes. It would
probably also make sense to forbid changing the filter sinks' volume, but
that's not strictly necessary, and currently changing a filter sink's volume
changes actually the hardware sink's volume, and from there it propagates to
all filter sinks ("funny" effects are expected when adjusting a single
channel in cases where all sinks don't have the same channel maps).

This patch is based on the work of Marc-André Lureau, who did the
initial implementation for Pulseaudio 0.9.15.
