2010-05-13[tegra ALSA] Updating sndfx header fileVijay Mali
In order to keep sndfx file in sync with audiofx header file updating tegra_sndfx.h with structures and definitions, made the corresponding changes in code. Verified both playback and record are working fine.

2010-05-10tegra ALSA: Do not queue buffers to the mixer in stopped stateSandeep Shinde
In SNDRV_PCM_TRIGGER_STOP state of the driver, if a buffer gets queued then it might not be returned back as it never gets rendered. In this scenario play_thread never exits as it keep on waiting for receiving all the buffers back from mixer before exiting. This is to solve bug 684393. In case of START->STOP->START scenario (happens in case of underruns), without closing the stream, there will not be any buffer loss as buffers are queued by application at appl_ptr and they remain there, once next START is called, they will be picked up for the playback.

2010-05-07tegra ALSA: Replacing completion object with wait_queue_head_tSandeep Shinde
Following are the changes done: - Removed completion object appl_ptr_comp used for waiting for app buffers when buffer_in_quque=0. - If a completion object wakes-up after every 120 seconds if not signalled during that time. - Now using wait_queue_head_t which suits the purpose better. - Removed play_thread running dependency on shutdown_thrd as it is no more required. - Removed label EXIT from play_thread All these changes were done based on comments from Google. Refer to below issues for the complete discussion. http://codereview.chromium.org/1705013/show Change-Id: Id902a73f704ddf38ec8b9071bc36ee0f6db89f30 Reviewed-on: http://git-master/r/1305 Reviewed-by: Manjula Gupta <magupta@nvidia.com> Tested-by: Manjula Gupta <magupta@nvidia.com> Reviewed-by: Gary King <gking@nvidia.com>
2010-05-03tegra ALSA : Handle Underrun CaseManjula Gupta
In case of underrun application triggers stop and starts the playback again, don't exit the thread in case of stop. underrun can happen when an application does not feed new samples in time to alsa-lib (due to CPU usage). With this change breaks may be observed in case of underrun which cannot be avoided, but the application will finish the playback and exits gracefully. For bug:663146 [LDK/Chromium/ALSA/Stability] "underrun!!!" (pcm_write:1442: write error: Input/output error) issues in ALSA while playback.

2010-04-27tegra ALSA: Fixing a hang in streaming playbackSandeep Shinde
In playback, play_thread hangs in case there is no continuous flow of buffers. That is when buffer_queue variable becomes 0 inside play_thread, it might hang on waiting for a semaphore. This conditions always happens in case of streaming playback, where buffer supply may not be continuous at the start. Resolved this hang by making use of ack function available for ALSA driver, this function is called from ALSA middleware whenever application buffer is supplied. Incorporated few more review comments.

Subject: [PATCH] aaci: ARM1176 aaci-pl041 AC97 register read timeout After a reboot on an ARM1176 which amounts to a softreset, it has been noted that the ALSA driver does not get registered and the probe fails with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process of reading from a register the SL1TxBusy bit is set indicating that the transceiver is busy and remains so until the default timeout occurs. Set the Power down register 0x26 to an arbitrary value as specified in the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take their default state.

2009-02-19sound: virtuoso: revert "do not overwrite EEPROM on Xonar D2/D2X"Clemens Ladisch
This reverts commit 7e86c0e6850504ec9516b953f316a47277825e33 ("do not overwrite EEPROM on Xonar D2/D2X") because it did not actually help with the problem. More user reports show that the overwriting of the EEPROM is not triggered by using this driver but by installing Linux, and that the installation of any other operating system (even one without any CMI8788 driver) has the same effect. In other words, the presence of this driver does not have any effect on the occurrence of the error. (So far, the available evidence seems to point to a BIOS bug.) Furthermore, it turns out that the EEPROM chip is protected against stray write commands by the command format and by requiring a separate write-enable command, so the error scenario in the previous commit (that SPI writes can be misinterpreted as an EEPROM write command) is not even theoretically possible. The mixer control that was removed as a consequence of the previous commit can only be partially emulated in userspace, which also means it cannot be seen be the in-kernel OSS API emulation, so it is better to revert that change.
