ALSA: Use %pV for snd_printk()

2011-06-10T13:35:20Z

Clean up snd_printk() helper using the %pV prefix for recursive printks. This also automagically fixes an Oops with RO/NX-enabled modules. Tested-by: Maarten Lankhorst Signed-off-by: Takashi Iwai

ALSA: core: remove unused variables.

Drop a few variables that are never read. Signed-off-by: Luca Tettamanti Signed-off-by: Takashi Iwai

ALSA: PCM - Don't check DMA time-out too shortly

2011-05-26T06:09:38Z

When the PCM period size is set larger than 10 seconds, currently the PCM core may abort the operation with DMA-error due to the fixed timeout for 10 seconds. A similar problem is seen in the drain operation that has a fixed timeout of 10 seconds, too. This patch fixes the timeout length depending on the period size and rate, also including the consideration of no_period_wakeup flag. Reported-by: Raymond Yau Signed-off-by: Takashi Iwai

ALSA: sound, core, pcm_lib: fix xrun_log

2011-05-19T05:18:56Z

The xrun_log function was augmented with the in_interrupt parameter whereas the empty macro definition used when xrun logging is disabled was not. Add a third parameter to the empty macro definition so as to not cause compiler errors when xrun logging (CONFIG_SND_PCM_XRUN_DEBUG) is disabled.

ALSA: sound, core, pcm_lib: xrun_log: log also in_interrupt

2011-05-18T15:12:39Z

When debugging pcm drivers I found the "period" or "hw" prefix printed by either XRUN_DEBUG_PERIODUPDATE or XRUN_DEBUG_PERIODUPDATE events, respectively to be very useful is observing the interplay between interrupt-context updates and syscall-context updates. Similarly, when debugging overruns with XRUN_DEBUG_LOG it is useful to see the context of the last 10 positions. Add an in_interrupt member to hwptr_log_entry which stores the value of the in_interrupt parameter of snd_pcm_update_hw_ptr0 when the log entry is created. Print a "[Q]" prefix when dumping the log entries if in_interrupt was true. Signed-off-by: Ben Gardiner Signed-off-by: Takashi Iwai

ALSA: core - Don't use "default' for default

2011-04-04T10:43:23Z

The card-id parser assigns the string "default" when no appropriate word is found in the card name. But this string may confuse the alsa-lib, so better to avoid. Use "Default" now instead. Signed-off-by: Takashi Iwai

ALSA: pcm: fix infinite loop in snd_pcm_update_hw_ptr0()

2011-04-01T16:01:23Z

When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares the current time against the time estimated for the current hardware pointer to detect xruns. The somewhat fuzzy threshold in the while loop makes it possible that hdelta becomes negative; the comparison being done with unsigned types then makes the loop go through the entire 263 negative range, and, depending on the value, never reach an unsigned value that is small enough to stop the loop. Doing this with interrupts disabled results in the machine locking up. To prevent this, ensure that the loop condition uses signed types for both operands so that the comparison is correctly done. Many thanks to Kelly Anderson for debugging this. Reported-by: Nix Reported-by: "Christopher K."
