[alsa-devel] [PATCH] ASoC: omap McBSP: Clear rx_irq at probe time for OMAP4
by Peter Ujfalusi 08 Mar '12

08 Mar '12

On OMAP4 we have one interrupt line per McBSP port. At proble time tx, and rx irq value will be -ENXIO, and only the tx irq will get corrected. In omap_mcbsp_request if the rx_irq is not 0 we proceed, and try to request the interrupt, which will fail on OMAP4 (rx_irq == -6). To avoid this error, clear the rx_irq at probe time on OMAP4.

[alsa-devel] [PATCH] ASoC: dapm: Add platform stream event support.
by Liam Girdwood 07 Mar '12

07 Mar '12

Currently stream events are only perfomed on codec stream widgets only. There is now a need to be able to perform stream events on platform widgets too. e.g. we have the ABE platform driver with several DAI links to dummy codecs. We need to be able to perform stream events on any of the dummy codec DAI links. This patch also removes the snd_soc_dai * parameter since it's already contained within the rtd * parameter. Finally makle stream event return void since no one checks it anyway.

[alsa-devel] ASOC - Codecs : Renaming of spdif_tranceiver.c
by Nitin PAI 07 Mar '12

07 Mar '12

Hi, In my project I am feeling of need to have generic_codec. This will provide the required codec_dais for the usecases like -HDMI/SPDIF where there is no codec involved. -For audio over MOST, where CPLD/glue logic is used -For complex audio DSPs connected which will be mostly programmed in the user-space. -SOC manufactures who would like to ship their drivers without having to know what will be the final codec that will be present in the system. Currently there is spdif_tranceiver.c which serves the purpose for spdif, but using this for other usecases will create confusion while shipping the code. What is the best way to carry forward? 1) Use spdif_tranceiver.c for all the purpose. disadvantage: this will create more confusion while shipping. 2)Deprecate spdif_transciever.c and call it generic_codec. Change the dai names and the function names. 3)Create another generic_codec.c and keep the spdif_transceiver.c and deprecate the latter in next version. 4) Any other ideas ? Thanks, Nitin

[alsa-devel] [RFC 0/7] ASoC: Introduce dmaengine pcm helper functions
by Lars-Peter Clausen 07 Mar '12

07 Mar '12

Same series as send out yesterday (sans the cleanup patches which already have been applied), since I forgot to Cc alsa-devel. Sorry for the noice if you got the series twice. This patch series introduces a new set of helper functions for dmaengine based PCM drivers. Currently we have 6 different dmaengine based PCM drivers which are all more or less similar in structure, but all have also individual requirements which can't easily be generalized. So that's why this series does not introduce a generic dmaengine PCM driver but rather a set of helper functions which can be used to implement the common bits between such dmaengine based PCM drivers. The helper functions only provide infrastructure code for dmaengines which provide thed evice_prep_dma_cyclic. While it is possible to add support for dmaengine, which only provide device_prep_slave_sg, it is in my opinion a better idea to either implement the missing functionality in the dmaengine driver or provide a emulation layer for cyclic transfer within the dmaengine framework itself. This has the advantage that it is also available outside of ALSA. This series converts the three PCM drivers which already use the circular dmaengine prepare function. Since I don't have access to hardware using the converted drivers the patches have only been compile tested. But the helper functions introduced in this series have been runtime tested with a platform which is not upstream yet. The first two patches restructure the iMX and MXS drivers to request their DMA channel in the PCM open callback instead of the hwparams callback. This is done to make their structure more similar to what it will be when using the helper functions and make the actual patch converting them to the new dmaengine PCM helper functions less intrusive. The next patch introduces the helper functions and the last three patches respectively convert the imx, mxs and ep39xx dmaengine based PCM drivers to use the new set of helper functions. The set of helper functions consists of a open, a close, a trigger and a pointer callback and also a function to convert hwparams to a dma_slave_config. The trigger and pointer callbacks can usually be used directly for the pcm_ops callbacks. The open callback wants to be called from a driver specific open function which may do some driver specific setup tasks and provide the helper open callback with a dma filter function. If the driver specific open functions allocates resources they need to be freed in a driver specific close function which has to call the helper close callback. If not the helper close callback can be assigned directly to the pcm_ops struct. If a driver needs to keep additional driver specific data around it can be done by using snd_dmaengine_pcm_{get,set}_data. Normally a driver should not require to keep additional data around, but all of the converted drivers need this, because of this horrible abusive pattern where the dma channels private field gets assigned configuration data in the filter callback. We should hopefully be able to get rid of this pattern with Guennadi Liakhovetski's patches[1], which add a slave configuration parameter to dma_request_channel, and with it the need for storing extra private data. While the DMA helper functions only use generic ALSA functions and nothing ASoC specific I've placed the, under ASoC for now since the only users are ASoC driver. - Lars [1] https://lkml.org/lkml/2012/2/1/227 Lars-Peter Clausen (7): ASoC: imx-ssi: Set dma data early ASoC: imx-pcm: Request DMA channel early ASoC: mxs-pcm: Request DMA channel early ASoC: Add dmaengine PCM helper functions ASoC: imx-pcm-dma: Use dmaengine PCM helper functions ASoC: mxs-pcm: Use dmaengine PCM helper functions ASoC: ep93xx-pcm: Use dmaengine PCM helper functions include/sound/dmaengine_pcm.h | 49 +++++++ sound/soc/Kconfig | 3 + sound/soc/Makefile | 3 + sound/soc/ep93xx/Kconfig | 1 + sound/soc/ep93xx/ep93xx-pcm.c | 148 +++----------------- sound/soc/imx/Kconfig | 1 + sound/soc/imx/imx-pcm-dma-mx2.c | 196 ++++---------------------- sound/soc/imx/imx-ssi.c | 28 +++- sound/soc/mxs/Kconfig | 1 + sound/soc/mxs/mxs-pcm.c | 152 ++++----------------- sound/soc/mxs/mxs-pcm.h | 12 -- sound/soc/soc-dmaengine-pcm.c | 287 +++++++++++++++++++++++++++++++++++++++ 12 files changed, 443 insertions(+), 438 deletions(-) create mode 100644 include/sound/dmaengine_pcm.h create mode 100644 sound/soc/soc-dmaengine-pcm.c -- 1.7.9
