| | | | | | | | | | | | | | | | | | | | | | | | | | | ATI controllers (at least some SB0600 models) appear buggy to handle 64bit DMA. As a workaround, reset GCAP bit0 and let the driver to use only 32bit DMA on these controllers. Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | | ALSA: Fix vunmap and free order in snd_free_sgbuf_pages()Takashi Iwai2009-03-181-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In snd_free_sgbuf_pags(), vunmap() is called after releasing the SG pages, and it causes errors on Xen as Xen manages the pages differently. Although no significant errors have been reported on the actual hardware, this order should be fixed other way round, first vunmap() then free pages.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the time of initialization, SNDRV_MIXER_OSS_PRESENT_PVOLUME bit is not set for MIC (slot 7). So, the same should not be checked when an application tries to do gain control for audio recording devices. Just check slot->present for SNDRV_MIXER_OSS_PRESENT_CVOLUME independently. Verified with a simple application which opens /dev/dsp for recording and /dev/mixer for volume control. Have tested two usb audio mic devices.

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.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the jack layer refers to card->longname as a part of its input device name string. However, longname is often really long and way too ugly as an identifier, such as, "HDA Intel at 0xf8400000 irq 21". This patch changes the code to use card->shortname instead. The shortname string contains usually the h/w vendor and product names but without messy I/O port or IRQ numbers. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | * | ALSA: hda - enable HDMI audio pin out at module loading timeWu Fengguang2009-02-111-23/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We found that enabling/disabling HDMI audio pin out at stream start/stop time will kill the leading 500ms or so sound samples. Avoid this by enabling pin out once and for ever at module loading time. The leading ~500ms audio samples will still be lost when switching from X-channel playback to Y-channel playback where X != Y. However there's no much we can do about it: the audio infoframe has to change and it looks like either G45 or YAMAHA requires some time to switch the configuration.

| | * | ALSA: hda - allow multi-channel HDMI audio playback when ELD is not presentWu Fengguang2009-02-111-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The YAMAHA AV-X1800 requires audio infoframe to include speaker-channel mapping to play >2 channel HDMI audio. In theory that mapping should be derived from its speaker configurations contained in its ELD. However we currently cannot get ELD in console before the KMS functionalities are ready. This is a more or less general issue at least in the near future. As a workaround, we propose to allow playback of mult-channel audio when ELD is not available.
