[alsa-devel] [PATCH v3 0/2] ALSA controls management using index/device/sub-devices fields
by Arnaud Pouliquen 01 Dec '16

01 Dec '16

V3: I changed "RFC" prefix to "PATCH", hoping that patchset is enough mature in term of code and discussions, to be considered as a potential patch... Previous discussions summary: - topic of the patchset: Patch concerns ASoc DAI drivers. Aim is to be able to instantiate PCM control using device field according to the associated PCM char device. For this, a relationship between DAIs PCM control and PCM char device needs to be establish. => Proposal is to add field in DAI driver struct to declare PCM controls that need to be linked to PCM character device on DAI link probing. - Limitation of the patchset: This patchset seems only a first step as 2 concerns are been highlighted: - Patch is limited to "static" DAI-link. This not responds to backend (no_pcm dai links) and some none-DAI codecs, that could register PCm controls. In theses cases it is not possible to establish relationship during probe. => No solution proposed for time beeing. - This patchset does not fix conflict of 2 "identical" PCM controls declared by 2 drivers. For instance, a conflict can exist between a PCM control created in DAI driver and the same control declared in a codec driver. As index field is forced to 0, prefix should be used in codec. => To discuss solution in a separate thread as issue already present without this patchset several approaches seem possible like using index field ( control auto indexation in ASoC) or prefix in Naming. Changes: - [PATCH v3 1/2] ASoC: core: allow DAI PCM controls bound to PCM device Code optimization based on Takashi Sakamoto suggestion - [RFC V2 3/3] ASoC: hdmi-codec: Example of PCM control bound to PCM device for multi patch suppressed as it was send as example in previous version. Patch is valid but can have impact on existing drivers as control device field value is updated - [PATCH v3 2/2] ASoC: sti: bind pcm controls to pcm device. No change vs V2 V2: http://www.spinics.net/lists/alsa-devel/msg57045.html Aim of this version is to continue discussion on DAI PCM control focused on ASoC drivers. In this V2 implementation in Soc-core is simplified to limit impact on existing code. Update of the RFC V1 based on discussions: - [RFC 4/4] iecset: allow to select control with device and sub-device numbers no more part of the RFC V2, will be discussed in a separate thread - [RFC 2/4] ALSA: control: increment index field for duplicated control. no more part of the RFC V2, no more need as RFC subject is PCM controls - [RFC V2 1/3] ASoC: core: allow DAI PCM controls bound to PCM device Patch reworked from V1 to simplify implementation - Binding is not done for Dai links tagged with no_pcm (DPCM). - no more possibility to add the controls after the DAI link probing. - [RFC V2 2/3] ASoC: sti: bind PCM controls to PCM device. - [RFC V2 3/3] ASoC: hdmi-codec: Example of PCM control bound to PCM device for multi Example of implementation in STI DAI driver and HDMI-codec drivers V1: http://www.spinics.net/lists/alsa-devel/msg56479.html 1) Alsa-utils patch - iecset: allow to select control with device and sub-device numbers This patch allows to access to 2 iec controls differentiated by device/sub-devices numbers => For me, this patch is mandatory to be able to address the ASoC IEC controls, in case of no fix is implemented to allows index field update in ASoC. 2) Alsa driver patches - ASoC: core: allow PCM control binding to PCM device Add relationship between DAIs PCM controls and PCM device. - ALSA: control: increment index field for duplicated control. Generic implementation of the patch proposed in HDA driver (http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=ea9b…) - ASoC: sti: use bind_pcm_ctl implementation of bind_pcm_ctl for sti driver.

[alsa-devel] [PATCH v2 1/1] ALSA: SOC: DMA: access buffer pointer atomically
by Jiada Wang 01 Dec '16

01 Dec '16

From: Andreas Pape <apape(a)de.adit-jv.com> Setting pointer and afterwards check for wrap around leads to the possibility of returning the inconsistent pointer position. This patch accesses buffer pointer atomically to avoid this issue. v2: use READ_ONCE and WRITE_ONCE to ensure read/write of buffer pointer in only one access also updates snd_dmaengine_pcm_pointer_no_residue to ensure atomic access Signed-off-by: Andreas Pape <apape(a)de.adit-jv.com> Signed-off-by: Jiada Wang <jiada_wang(a)mentor.com> --- sound/core/pcm_dmaengine.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/sound/core/pcm_dmaengine.c b/sound/core/pcm_dmaengine.c index 8eb58c7..b6255fd 100644 --- a/sound/core/pcm_dmaengine.c +++ b/sound/core/pcm_dmaengine.c @@ -139,12 +139,14 @@ EXPORT_SYMBOL_GPL(snd_dmaengine_pcm_set_config_from_dai_data); static void dmaengine_pcm_dma_complete(void *arg) { + unsigned int new_pos; struct snd_pcm_substream *substream = arg; struct dmaengine_pcm_runtime_data *prtd = substream_to_prtd(substream); - prtd->pos += snd_pcm_lib_period_bytes(substream); - if (prtd->pos >= snd_pcm_lib_buffer_bytes(substream)) - prtd->pos = 0; + new_pos = prtd->pos + snd_pcm_lib_period_bytes(substream); + if (new_pos >= snd_pcm_lib_buffer_bytes(substream)) + new_pos = 0; + WRITE_ONCE(prtd->pos, new_pos); snd_pcm_period_elapsed(substream); } @@ -235,7 +237,7 @@ EXPORT_SYMBOL_GPL(snd_dmaengine_pcm_trigger); snd_pcm_uframes_t snd_dmaengine_pcm_pointer_no_residue(struct snd_pcm_substream *substream) { struct dmaengine_pcm_runtime_data *prtd = substream_to_prtd(substream); - return bytes_to_frames(substream->runtime, prtd->pos); + return bytes_to_frames(substream->runtime, READ_ONCE(prtd->pos)); } EXPORT_SYMBOL_GPL(snd_dmaengine_pcm_pointer_no_residue); -- 2.9.3

[alsa-devel] [PATCH 39/39] Annotate hardware config module parameters in sound/pci/
by David Howells 01 Dec '16

01 Dec '16

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in sound/pci/.

[alsa-devel] [PATCH 37/39] Annotate hardware config module parameters in sound/isa/
by David Howells 01 Dec '16

01 Dec '16

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in sound/isa/.

[alsa-devel] [PATCH 36/39] Annotate hardware config module parameters in sound/drivers/
by David Howells 01 Dec '16

01 Dec '16

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in sound/drivers/.

[alsa-devel] [PATCH V2 0/5] ASoC/arizona: Ensure pin searches use widget name prefix
by Richard Fitzgerald 01 Dec '16

01 Dec '16

The name of a codec pin can have an optional prefix string, which is defined by the audio machine driver. The snd_soc_dapm_x_pin functions take the fully-specified name including the prefix and so the existing code would fail to find the pin if the audio machine driver had added a prefix. This patch chain adds new helper functions that take a non-prefixed name for a specific ASoC component and internally add that component's prefix. The other patches update the arizona drivers to use these new functions.
