2008-05-20snd-pcsp: use HRTIMER_CB_SOFTIRQStas Sergeev
Change HRTIMER_CB_IRQSAFE to HRTIMER_CB_SOFTIRQ, as suggested by Thomas Gleixner. That solves the lock dependancy reported in Bug #10701. That also allows to call hrtimer_start() directly, tasklet "stupid hack" removed.

2008-05-19snd-pcsp: silent misleading warningStas Sergeev
It appears that alsa allows a sound buffer with size not evenly devided by the period size. This triggers a warning in snd-pcsp and floods the log. As a quick fix, the warning should be disabled. Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-05-19snd-pcsp: depend on CONFIG_EXPERIMENTALStas Sergeev
Considering all the feedbacks I got, depending snd-pcsp on CONFIG_EXPERIMENTAL looks like the only safe way to get out of all the troubles at one go. :) Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-05-19snd-pcsp: put back the compatibility code for the older alsa-libsStas Sergeev
The attached patch adds back the compatibility code, allowing the driver to work with older alsa-libs. The removal was premature, it breaks the real-life configs. Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-05-19snd-pcsp: adjust help texts to frighten usersStas Sergeev
Added the warning text to the help of snd-pcsp about the possible problem with this driver so that user can know of the problem in advance. Also, removed the obsoleted text about ancient pc-speaker patch in CONFIG_SOUND help. Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-04-24[ALSA] snd-dummy - better realtime app supportAhmet İnan
when the time interval for a period is smaller than kernel HZ, then snd-aloop and snd-dummy cannot call snd_pcm_period_elapsed as fast enough annymore. this happens for example with games. but the app still needs to see, that the buffer actually did go further, which is provided by these patches.

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.

The original MPU-401 does not send an ACK byte after processing the ENTER_UART command, so we better do not try to wait for it. Many clones get this wrong and do send an ACK, but when interpreting it as MIDI, it is just a harmless Active Sensing message, and it is likely to be read and discarded by the interrupt handler before the MIDI input device is triggered.
