Hi alsa-devel ML: Could you merge this 000-alc700-intel.patch file to your ALSA driver? I changed "Intel debug" to "Intel Reference board".

Thanks, it looks good now. One thing to be changed is the name "Intel debug". Maybe "Intel Reference board" or such would fit better. In anyway, could you submit the patch to alsa-devel ML?

[alsa-devel] [PATCH] sound: Convert timers to use timer_setup()
by Kees Cook 26 Oct '17

26 Oct '17

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. These are all the "mechanical" changes remaining in the sound subsystem.

[alsa-devel] [PATCH] ASoC: Intel: Skylake: Decrease loglevel for topology loading
by Chintan Patel 25 Oct '17

25 Oct '17

In case of failure in loading customize topology firmware, dfw_sst.bin gets loaded. However, current log provides this message as error even after successfully falling back to default topology "dfw_sst.bin". Hence to convey proper message, changing log level and message.

[alsa-devel] [PATCH v2 0/7] ASoC: Intel: Skylake: Add a clk driver to enable ssp clks early
by Subhransu S. Prusty 25 Oct '17

25 Oct '17

For certain platforms clocks (mclk/sclk/fs) are required to be up before the stream start. Example: some codecs needs the mclk/sclk/fs to be enabled early for a successful clock synchronization. Some patforms require clock to be enabled at boot and be always ON By sending set_dma_control IPC (with the i2s blobs queried from NHLT), these clocks can be enabled early after the firmware is downloaded. With this series, a virtual clock driver is created which provides interface to send the required IPCs from machine driver to enable the clocks. NHLT is parsed during probe and the clock information is populated. The pointer to blob is cached and sent along with the set_dma_control IPC structure during the clk prepare/unprepare callback. Clocks are created for a ssp if the nhlt table has endpoint configuration for that particular ssp. Skylake driver creates a platform driver with the clock information and register the clk ops callback. kabylake machine driver uses the clock interface to enable the clocks early as it is required by the rt5663 driver for clock synchronization. set_dma_control API can be used with different payload configuration. Modify the arguments to take configurable parameters. v1 -> v2 - Register parent clocks with skylake device. With the patch "clk: Add support for runtime PM" soon to be merged will help DSP to stay active on call to clock enable.

[alsa-devel] [PATCH] ALSA: sb: Minor optimization / fix of timer usage in sb8_midi.c
by Takashi Iwai 25 Oct '17

25 Oct '17

Currently the SB8 MIDI code sets up the timer object at each time before scheduling it at trigger callback, but basically this is superfluous once after set up. Also, the code misses the del_timer_sync() call that may leave a race condition for use-after-free. This patch addresses these issues, moving timer_setup() to snd_sb8dsp_midi(), and adding the del_timer_sync() call at snd_sb8dsp_midi_output_trigger() to make sure.

[alsa-devel] [RFCv3][PATCH 00/39] axfer: rewrite aplay, adding 'timer-based scheduling' option
by Takashi Sakamoto 25 Oct '17

25 Oct '17

Hi, This 3rd RFC patchset updates my previous one: [alsa-devel] [RFCv2][PATCH 00/38] alsa-utils: axfer: rewrite aplay http://mailman.alsa-project.org/pipermail/alsa-devel/2017-September/125574.… For aim of this rewrite and its intension, please refer to my former posts. In this version, I add an option to support 'timer-based scheduling' scenario, which PulseAudio developers introduced. Please refer to patch 32: * axfer: add support for timer-based MMAP operation You can use this mode by adding '-sched-type=timer' option into command line. The other difference from my previous one: - fix some bugs to handle non-interleaved buffer on mapped page frame. - use snd_pcm_status() instead of snd_pcm_state() to execute hwsync. - minor fixes. In my plan, this is the last version including below patches. In next post, options added by below patches are categorized as obsoleted: * axfer: add an option to support volume unit meter * axfer: add a unit test for vumeter calculation * axfer: add an option for formatted filename * axfer: add an option to handle key events * axfer: add a parser for channel map API * axfer: add a feature to generate a file for process id Additionally, for next post, I'll prepare for help messages and man for this program.

[alsa-devel] snd_pcm_ioplug_avail_update() confusion
by Rob Duncan 24 Oct '17

24 Oct '17

I'm working on an external IO plugin based on ioplug and I'm confused about the behavior of snd_pcm_ioplug_avail_update(). Specifically this call (src/pcm/pcm_ioplug.c:657): result = io->data->callback->transfer(io->data, areas, offset, size); Why isn't there a subsequent call to snd_pcm_mmap_appl_forward() like there is in ioplug_priv_transfer_areas()? It seems that without such a call the captured data will be lost, or have I missed something? Thanks, Rob.

[alsa-devel] New to this list. Proposed patch to soc-utils.c
by Albin Stigö 24 Oct '17

24 Oct '17

Hello, I'm new to this list so please excuse my ignorance. I'm an anesthesiologist by profession so I might be a bit out of my depth here... I was doing some experimentation with custom i2s codecs (FPGAs) using the snd-soc-dummy codec (defined in soc-utils.c). I found this codec to be needlessly restrictive with sample rates allowed (SNDRV_PCM_RATE_8000_192000). I needed to use more "exotic" sample rates so I came up with a patch. I purpose using SNDRV_PCM_RATE_KNOT and setting some limits: .rate_min = 8000, .rate_max = 384000, It's my understanding that SNDRV_PCM_RATE_CONTINIOUS is used for "known" rates and SNDRV_PCM_RATE_KNOT for more or less arbitrary rates? I'm willing to submit my patch but might need some mentoring in the process. I don't think this simple patch could break anything..? --Albin

[alsa-devel] [PATCH 0/6] ASoC: Intel: Skylake: Add a clk driver to enable ssp clks early
by Subhransu S. Prusty 24 Oct '17

24 Oct '17

For certain platforms we require to start the clocks (mclk/sclk/fs) before the stream start. Example: for few systems, codec needs the mclk/sclk/fs to be enabled early for a successful clock synchronization and for some others, clock need to be enabled at boot and should be ON always. By sending set_dma_control IPC (with the i2s blobs queried from NHLT), these clocks can be enabled early after the firmware is downloaded. With this series, a virtual clock driver is created which provides interface to send the required IPCs from machine driver to enable the clocks. NHLT is parsed during probe and the clock information is populated. The pointer to blob is cached and sent along with the set_dma_control IPC structure during the clk prepare/unprepare callback. Clocks are created for a ssp if the nhlt table has endpoint configuration for that particular ssp. Skylake driver creates a platform driver with the clock information and register the clk ops callback. kabylake machine driver uses the clock interface to enable the clocks early as it is required by the rt5663 driver for clock synchronization. set_dma_control API can be used with different payload configuration. Modify the arguments to take configurable parameters.

[alsa-devel] ASoC: writing basic custom codecs?
by Albin Stigö 24 Oct '17

24 Oct '17

Hello, I have implemented a custom i2s codec on an FPGA. Because of how the FPGA is clocked I'm getting samples at 39ksps, which to my surprise worked great after some simple kernel patching (the codec is bit & frame master). For experimentation I used the snd-soc-dummy coded defined in soc-utils.c. Now I'm trying to write a very simple codec to "lock" the rate to 39000: https://github.com/ast/vfzfpga-codec The driver loads just fine but I just get "not registered" when I try to use the codec. I feel I'm missing something very obvious here. I've been through the documentation and tried to read the sources but I'm a bit stuck.. What am I missing? --Albin

[alsa-devel] Prague Audio miniconference - draft schedule
by Mark Brown 24 Oct '17

24 Oct '17

As previously announced[1] by Takashi our annual Linux audio miniconference will be held this year at the SuSE offices in Prague on Friday 27th October (the week of ELC-E). Thanks again to SuSE for sponsoring this. Following the earlier discussion I've pulled together a list of topics. I've put people's names against everything, mostly the people who suggested things but sometimes also other people who should probably be involved. I'm proposing that we work through things in roughly this order. Does this make sense to people? Any other topics? Summary - API status summary (tiwai) - Userspace release schedule - Docs - Dropping old drivers - Treble overview (Eric) - aplay rewrite (Sakamoto-san) ABI issues - USB PCM handling (tiwai) - mmap no IRQ (Eric) - TLV API issues (Sakamoto-san) - Obsolete dimen from struct snd_ctl_elem_info (Sakamoto-san) - Y2038 (tiwai) Future stuff/internals - Clock handling (Peter) - CCF, multi-clock selection - Digital domains (Charles/Lars/Morimoto-san) - Large regmaps (Charles) [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2017-August/124623.html

[alsa-devel] [PATCH v2 34/37] ALSA/dummy: Replace tasklet with softirq hrtimer
by Anna-Maria Gleixner 24 Oct '17

24 Oct '17

From: Thomas Gleixner <tglx(a)linutronix.de> The tasklet is used to defer the execution of snd_pcm_period_elapsed() to the softirq context. Using the HRTIMER_MODE_SOFT mode invokes the timer callback in softirq context as well which renders the tasklet useless.

[alsa-devel] Prague Audio miniconference - topics for discussion?
by Mark Brown 23 Oct '17

23 Oct '17

As previously announced[1] by Takashi our annual Linux audio miniconference will be held this year at the SuSE offices in Prague on 27th October (the week of ELC-E). Thanks again to SuSe for sponsoring this. As with previous years let's pull together an agenda through a mailing list discussion - if people could reply to this mail with any topics they'd like to discuss we can take it from there. Of course if we can sort things out more quickly via the mailing list that's even better! I'll start things off by mentining the TLV issues that Sakamoto-san was raising - do we have any better ideas to handle larger binary controls than what's currently being done?
