[alsa-devel] PATCH: Fix snd-hda-intel boot hang on ASUS A8N-VM
by Brian Lindholm 21 Mar '10

21 Mar '10

This patch fixes a regression in 2.6.33.x. Was working in 2.6.32.x. Symptom: Hang on boot at "HDA Intel". Boots only if on-board sound is disabled or if "snd-hda-intel.enable_msi=0" is appended to boot parameters. Machine: ASUS A8N-VM with Athlon-X2 processor. Relevant output from lspci -nn: 00:10.1 Audio device [0403]: nVidia Corporation MCP51 High Definition Audio [10de:026c] (rev a2) Relevant output from alsa-info.sh: 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) 00:10.1 0403: 10de:026c (rev a2) Subsystem: 10de:cb84 Proposed patch (which has been confirmed to allow boot, with sound active): diff -dru linux-2.6.33-orig/sound/pci/hda/hda_intel.c linux-2.6.33/sound/pci/hda/hda_intel.c --- linux-2.6.33-orig/sound/pci/hda/hda_intel.c 2010-03-16 17:33:23.487938000 -0400 +++ linux-2.6.33/sound/pci/hda/hda_intel.c 2010-03-16 17:40:36.141225010 -0400 @@ -2354,6 +2354,7 @@ static void __devinit check_probe_mask(s static struct snd_pci_quirk msi_black_list[] __devinitdata = { SND_PCI_QUIRK(0x1043, 0x81f2, "ASUS", 0), /* Athlon64 X2 + nvidia */ SND_PCI_QUIRK(0x1043, 0x81f6, "ASUS", 0), /* nvidia */ + SND_PCI_QUIRK(0x10de, 0xcb84, "ASUS", 0), /* nvidia */ {} }; Signed-off-by: Brian E Lindholm <brian_lindholm(a)users.sourceforge.net>

[alsa-devel] question about sound/oss/vidc.c
by Julia Lawall 20 Mar '10

20 Mar '10

In sound/oss/vidc.c, the function vidc_audio_trigger contains thefollowing code: struct audio_operations *adev = audio_devs[dev]; if (enable_bits & PCM_ENABLE_OUTPUT) { if (!(adev->flags & DMA_ACTIVE)) { unsigned long flags; local_irq_save(flags); /* prevent recusion */ adev->flags |= DMA_ACTIVE; ... } } I wonder if the use of DMA_ACTIVE is correct? This constant is defined inthe file sound/oss/dev_table.h within the definition of the structure dma_buffparms. But here it is being used with the structure audio_operations. The definition of audio_operations also contains the definitions of some constants. Indeed, one of them, DMA_DUPLEX has the same value as DMA_ACTIVE. thanks, julia

[alsa-devel] Problem about building alsa driver for wm8974 on i.mx27 platform
by jjinfo＠nudt.edu.cn 20 Mar '10

20 Mar '10

Hi, I'm trying to build alsa-1.0.22 driver for my wm8974 codec on i.Mx27 platform. I need to cross compile it on x86 platform for i.Mx27. Here is my configure options: ./configure --wit-cross=arm-linux- --with-kernel=<path-to-ARM-kernel> --with-build=<path-to-kernel> When configure process completes, a "toplevel.config" file is generated. But in the toplevel.config file, the following config options are not set by the configure process( which prevent wm8974 driver from being built): CONFIG_SND_MX1_MX2_SOC= CONFIG_ARCH_MX2= CONFIG_ARCH_MX1= CONFIG_SND_MXC_SOC_SSI= CONFIG_SND_SOC_MX27VIS_WM8974= CONFIG_MACH_MX27= CONFIG_MACH_IMX27_VISSTRIM_M10= Since the default value of "--with-cards" is "all", why these options are not set? (Event I specifiy --with-cards=soc, mx1-mx2-soc, soc-mx27vis-wm8974, these options are still not set in toplevel.config.) Any idea? Regards, Jie

[alsa-devel] [PATCH v2] ASoC: remove a card from the list, if instantiation failed
by Guennadi Liakhovetski 19 Mar '10

19 Mar '10

If instantiation of a card failed, we still have to remove it from the card list on unregistration. This fixes an Oops on Migo-R, triggering, when after a failed firmware load attempt the driver modules are removed and re-inserted again.

[alsa-devel] Are ALSA io plugins implemented as threads or does ALSA use fork() ?
by Stefan Schoenleitner 19 Mar '10

19 Mar '10

Hello, from what I have learned so far ALSA io plugins are implemented as shared libraries with their entry point defined with the SND_PCM_PLUGIN_DEFINE_FUNC() macro. However, each plugin instance can only work for either the SND_PCM_STREAM_PLAYBACK or SND_PCM_STREAM_CAPTURE stream. Hence this is why io plugins supporting playback and capture usually set up their callback functions depending on what type of stream is used. For example in the pulseaudio io plugin, this is done with: pcm->io.callback = stream == SND_PCM_STREAM_PLAYBACK ? &pulse_playback_callback : &pulse_capture_callback; * If such a plugin is used for capture AND playback at the same time, it seems that two instances of the plugin need to be running, right ? * Are these instances running as separate processes (i.e. fork()) or are they implemented as threads ? How is this implemented internally in the ALSA code ? In my plugin I'm planning that both the playback and the capture plugin instances talk to a common data processing thread over shared buffers. The reason for this is that the data processing threads needs to have access to the capture and playback samples *at the same time*. I'm guessing that the plugin instances run with different PIDs so that I would need to use common IPC mechanisms in order to let them communicate with each other, right ? Hence my first approach would be to set up a common shared memory together with a semaphore so that only one process can access the shared memory at a time. Any better ideas ? cheers, Stefan
