[alsa-devel] [PATCH 00/17] ASoC: Towards a generic dmaengine PCM driver
by Lars-Peter Clausen 18 Apr '13

18 Apr '13

Hi, This series adds a (almost) generic dmaengine PCM driver for ASoC. The tegra, spear, omap, imx, mxs, ep93xx and ux500 platforms are converted to use the generic driver instead of their own custom implementation. The driver builds on top of the dmaengine PCM library and adds the missing bits. The driver was primarily built for handling devicetree based platforms, but the series also adds support for compat platforms which don't use devicetree yet or have to support non-devicetree instantiation for backwards compatibility. Since non of the converted platforms have devicetree support yet (at least not using the generic DMA bindings) this series doesn't enable devicetree support for them either. But enabling support for them is very easy and can be done by removing the SND_DMAENGINE_PCM_NO_DT flag for these platforms. For platforms using devicetree the DMA channels are requested early on before the ASoC platform driver is registered. This allows us, at least in theory, to use probe deferral if the DMA driver hasn't been probed yet. Unfortunately of_dma_request_slave_channel either returns a valid channel or NULL, so we can't distinguish between the case where there is no DMA channel assigned and the case where the DMA driver hasn't been probed yet. I plan to submit a patch which lets of_dma_request_slave_channel return a ERR_PTR, but for now the generic PCM dmaengine driver assumes that the DMA driver will always be probed before it. For the compat case the DMA channel gets requested from within the PCM driver's pcm_new callback. This requires some minor changes to some of the DAI drivers moving the initialization of the DAI DMA data pointer from the DAI startup callback to the DAI probe callback. Unfortunately the driver is not fully generic yet and we still need some platform specific data to make it work, but the plan is to eventually make the driver fully generic in the future. The platform specific bits currently are: * The snd_pcm_hardware struct which contains device specific parameters like the maximum period size and maximum number of periods as well as whether the driver supports pause and resume. The idea is to get rid of the per platform snd_pcm_hardware struct by extending the dmaengine API to a point where we can query all necessary information from the dmaengine driver to fill in the snd_pcm_hardware struct at runtime. * The size of the pre-allocated audio buffer. All platforms seem use different sizes and since some of them might be sensitive to changes to the buffer size this series keeps the original size for now. But we should probably try to decide on a sane default for this and maybe allow ASoC board drivers to overwrite it somehow. * A callback to fill in the dma_slave_config. Currently this is either NULL (for platforms which don't need to configure the DMA channel at runtime) or uses the generic snd_dmaengine_pcm_prepare_slave_config(), which uses snd_hwparams_to_dma_slave_config() and snd_dmaengine_pcm_set_config_from_dai_data(). The later requires the platform to use the generic DMA DAI data struct though, hopefully we'll be able to convert all platforms to use this generic struct, and once that's done we can always use snd_dmaengine_pcm_prepare_slave_config() unconditionally. * For platforms not using devicetree platforms a callback to request the dma channel. This can either be a completely custom function which returns the channel or a filter function which will be passed to dma_request_channel. The route forward here probably is to let the DAI driver provide the filter function or implement a table based DMA channel lookup like we have for other subsystems (like clk or regulator) where the board file provides a mapping based on the device name. Platforms which use the dmaengine pcm library but are not converted to the generic driver yet are atmel and mmp. mmp use a custom genalloc based memory allocator, we may add support for this to the generic driver at a later point. The atmel PCM driver is very interlocked with atmel SSC DAI driver, it'll probably require some serious refactoring before it can use the generic dmaengine PCM driver. The driver uses snd_pcm_lib_preallocate_pages to preallocate the memory buffer. snd_pcm_lib_preallocate_pages internally uses dma_alloc_coherent, while most of the platforms converted in this series use dma_alloc_writecombine. Laxman Dewangan submitted a patch[1] a couple of months ago to add support for dma_alloc_writecombine to snd_pcm_lib_preallocate_pages, I always thought the patch had been merged, but it looks like I was mistaken. So if there are concerns about performance regression due to using coherent instead of writecombine mappings we'll have to postpone converting these platforms until Laxman's patch has been merged. The compat path of this series hasn't been runtime tested yet and neither have the platforms which are converted in this series. I probably broke one or two of them by accident, so please test the patches.

[alsa-devel] [PATCH v4 00/10] ASoC: fsl-ssi: ac97-slave support
by Markus Pargmann 18 Apr '13

18 Apr '13

Hi, This series adds DT support for phycore-ac97. It is now based on the pcm dma cleanups from Lars. Beside ac97 support, the series adds fsl-ssi imx-pcm-fiq and generic DMA binding handling. Regards, Markus Changes in v4: - phycore-ac97 uses the iomux functions based on audmux phandle now. - fsl-ssi imx-pcm-fiq got some new comments about problems with imx-ssi and incompatible codecs Changes in v3: - Rebased onto pcm dma cleanup patches - A lot of cleanups for the fsl-ssi ac97 integration - Some small changes which are listed in the notes of the patches.

[alsa-devel] More ASoC updates for v3.10
by Mark Brown 18 Apr '13

18 Apr '13

The following changes since commit b02e48f2f8755e51fe8ce246988a29bd96f6b85e: MAINTAINERS: Update e-mail address (2013-04-12 11:53:41 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next for you to fetch changes up to 24568ea4bef5ab8106206eddf5512434421c00ed: Merge remote-tracking branch 'asoc/topic/max98088' into asoc-next (2013-04-18 15:05:35 +0100) There's a bunch of extra stuff in the diffstat/log since your for-next is further behind Linus' tree than one of my branches. ---------------------------------------------------------------- ASoC: More updates for v3.10 The main additional change here is Lars-Peter's DMA work plus the platform conversions which have been tested - getting this in mainline will make life easier for development after the merge window. These factor a large chunk of code out of the drivers for the platforms using dmaengine, greatly simplifying development. ---------------------------------------------------------------- Al Viro (3): ecryptfs: close rmmod race procfs: add proc_remove_subtree() palinfo fixes Alex Williamson (1): vfio-pci: Fix possible integer overflow Alexandre Belloni (1): gpio: pca953x: fix irq_domain_add_simple usage Alexey Khoroshilov (1): tty: mxser: fix cycle termination condition in mxser_probe() and mxser_module_init() Alexey Pelykh (1): OMAP/serial: Revert bad fix of Rx FIFO threshold granularity Andrea Arcangeli (2): x86/mm/cpa: Convert noop to functional fix x86/mm/cpa/selftest: Fix false positive in CPA self test Andrey Vagin (1): mnt: release locks on error path in do_loopback Arnd Bergmann (5): block: avoid using uninitialized value in from queue_var_store Merge tag 'mxs-fixes-3.9-4' of git://git.linaro.org/people/shawnguo/linux-2.6 into fixes Merge tag 'imx-fixes-3.9-5' of git://git.linaro.org/people/shawnguo/linux-2.6 into fixes Merge tag 'samsung-fixes-for-v3.9' of git://git.kernel.org/.../kgene/linux-samsung into fixes Merge tag 'mvebu_fixes_for_v3.9_round3' of git://git.infradead.org/users/jcooper/linux into fixes Artem Savkov (1): cfg80211: sched_scan_mtx lock in cfg80211_conn_work() Arun Easi (1): [SCSI] qla2xxx: Fix crash during firmware dump procedure.

[alsa-devel] [PATCH v3 0/5] ALSA: snd-usb: add support for DSD
by Daniel Mack 18 Apr '13

18 Apr '13

In contrast to the first two approaches, this one keeps the userspace unaware of the actual transport on the bus. More specifically, the DSD_U16_LE format may be implemented to actually send DOP samples to the device, depending on the quirks entries. Also, as there is quite some confusion in both data file formats as well as hardware sample formats about whether to stuff the oldest bit in the MSB or the LSB of a byte, ALSA defines that now to be in the MSB, as far as the ALSA userspace layer is concerned. The driver learned functions to re-encode the bytes according to what the hardware supports. I also wrote a very basic test tool which I published here: https://github.com/zonque/alsa-dsd-player Thanks, Daniel Daniel Mack (5): ALSA: add DSD formats ALSA: snd-usb: use ep->stride from urb callbacks ALSA: snd-usb: add support for DSD DOP stream transport ALSA: snd-usb: add support for bit-reversed byte formats ALSA: snd-usb: add quirks handler for DSD streams include/sound/pcm.h | 2 + include/uapi/sound/asound.h | 4 +- sound/core/pcm.c | 2 + sound/core/pcm_misc.c | 8 +++ sound/usb/card.h | 8 +++ sound/usb/endpoint.c | 9 ++++ sound/usb/format.c | 3 ++ sound/usb/pcm.c | 118 ++++++++++++++++++++++++++++++++++++------- sound/usb/quirks.c | 28 ++++++++++ sound/usb/quirks.h | 4 ++ 10 files changed, 167 insertions(+), 19 deletions(-) -- 1.7.10.4

That said if boards generally don't use external supplies and use the built in regulators then it's probably best to at least have the driver assume that by default. > > Bard: You are right.

Indeed, there definitely should be configuration - however what I was commenting on there was a user-visible ALSA control which should definitely go.
