* | sbc: ARMv6 optimized version of analysis filter for SBC encoderSiarhei Siamashka2011-03-143-0/+355

This code is also disabled when NEON is used (which is a lot better alternative). For additional safety ARM EABI is required and thumb mode should not be used.

* | sbc: added "cc" to the clobber list of mmx inline assemblySiarhei Siamashka2011-03-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 in all these places.
* | sbc: faster 'sbc_calculate_bits' functionSiarhei Siamashka2011-03-141-15/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By using SBC_ALWAYS_INLINE trick, the implementation of 'sbc_calculate_bits' function is split into two branches, each having 'subband' variable value known at compile time. It helps the compiler to generate more optimal code by saving at least one extra register, and also provides more obvious opportunities for loops unrolling.

* | sbc: new 'sbc_calc_scalefactors_j' function added to sbc primitivesSiarhei Siamashka2011-03-143-68/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code for scale factors calculation with joint stereo support has been moved to a separate function. It can get platform-specific SIMD optimizations later for best possible performance. But even this change in C code improves performance because of the use of __builtin_clz() instead of loops similar to what was done to sbc_calc_scalefactors earlier. Also technically it does loop unrolling by processing two channels at once, which might be either good or bad for performance (if the registers pressure is increased and more data is spilled to memory). But the benchmark from 32-bit x86 system (pentium-m) shows that it got clearly faster: $ time ./sbcenc.old -b53 -s8 -j test.au > /dev/null real 0m1.868s user 0m1.808s sys 0m0.048s $ time ./sbcenc.new -b53 -s8 -j test.au > /dev/null real 0m1.742s user 0m1.668s sys 0m0.064s

When set to "1" indicates that those algorithms shall be enabled by default and "0" means the headset probably have them active so they should be disabled in PA side.
* | bluetooth: fix a2dp_process_pushLuiz Augusto von Dentz2011-03-141-6/+12
| | | | | | | | | | | | Use minimum bitpool configured to get the maximum block_size possible, also remove checks for how much has been written when decoding sbc frames since the block size may change due to bitpool changes.
* | bluetooth: reduce bitpool if audio start skippingLuiz Augusto von Dentz2011-03-141-0/+71
| | | | | | | | | | | | | | When audio skips it could be that there is some bandwidth limitation in the link e.g. headset doesn't support EDR (< 2.0), and by reducing the bitpool it may find a better rate that either prevent the skips completely or at least reduce them.
* | bluetooth: handle Acquire API changeLuiz Augusto von Dentz2011-03-143-47/+12
| | | | | | | | | | | | Acquire now return input and output MTU of the file descriptor so it is no longer necessary to get those after acquiring the fd, which less round trips and faster response time when switching profiles.
* | cork-on-phone: Only cork (and subsequently uncork) streams that are not ↵Colin Guthrie2011-03-121-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | already corked. Although by "cork" I really mean "cork+mute" as that's what the module does. If e.g. Rhythmbox is paused when a phone call comes in, the current stream state will be corked and thus we should not track it for future uncorking when the phone call ends. Likewise if the stream is just muted (manually) we will not take any action either when the phone stream is seen first, nor when it disappears. Also add some additional debug messages.

* | alsa-mixer: When figuring out the max_dB of a path, use only channels that ↵Tanu Kaskinen2011-03-111-4/+9
| | | | | | | | | | | | | | | | | | | | | | are used by the path elements. Without this, p->max_dB could never be less than 0 dB, because the loop at the end of pa_alsa_path_probe() would reset p->max_dB to 0 as soon as the loop encountered a channel that wasn't touched by any element. There was a similar issue for p->min_dB too (it could never be more than 0 dB), which is also fixed by this patch.
* | alsa-mixer: Implement support for setting element specific upper limits for ↵Tanu Kaskinen2011-03-113-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | volume. This feature is mainly useful in embedded systems that have built-in speakers. In such situations the full audio path is known beforehand, so it's possible to know what is the maximum sensible volume, and any higher volume can be disabled. The volume limit is set in path configuration files in the [Element] section, using option "volume-limit". The value is the desired maximum volume step of the volume element.
* | dbus: Always accept mono volumes when setting device or stream volume.Tanu Kaskinen2011-03-112-10/+8
| | | | | | | | | | pa_sink_set_volume() and friends accept mono volumes too, so no need to impose unneeded restrictions in the D-Bus API.

* | alsa-mixer: Fix a git-am cockup in b0f72311Colin Guthrie2011-03-041-3/+3
| | | | | | | | | | | | | | | | | | | | It seems git managed to mess up a git-am with a patch from David which moved where this function was called element_probe to within itself (recursive which could normally lead to an infinite loop, but as it was now never called from anywhere else, this didn't happen). Thank you to Maarten for spotting and following up the issue.
