[PATCH] ALSA: memalloc: Add fallback SG-buffer allocations for x86
by Takashi Iwai 13 Apr '22

13 Apr '22

The recent change for memory allocator replaced the SG-buffer handling helper for x86 with the standard non-contiguous page handler. This works for most cases, but there is a corner case I obviously overlooked, namely, the fallback of non-contiguous handler without IOMMU. When the system runs without IOMMU, the core handler tries to use the continuous pages with a single SGL entry. It works nicely for most cases, but when the system memory gets fragmented, the large allocation may fail frequently. Ideally the non-contig handler could deal with the proper SG pages, it's cumbersome to extend for now. As a workaround, here we add new types for (minimalistic) SG allocations, instead, so that the allocator falls back to those types automatically when the allocation with the standard API failed. BTW, one better (but pretty minor) improvement from the previous SG-buffer code is that this provides the proper mmap support without the PCM's page fault handling.

[PATCH] ASoC: ti: osk5912: Make it CCF clk API compatible
by Janusz Krzysztofik 13 Apr '22

13 Apr '22

The driver, OMAP1 specific, now omits clk_prepare/unprepare() steps, not supported by OMAP1 custom implementation of clock API. However, non-CCF stubs of those functions exist for use on such platforms until converted to CCF. Update the driver to be compatible with CCF implementation of clock API.

[PATCH] firmware: cs_dsp: Fix overrun of unterminated control name string
by Richard Fitzgerald 12 Apr '22

12 Apr '22

For wmfw format v2 and later the coefficient name strings have a length field and are NOT null-terminated. Use kasprintf() to convert the unterminated string into a null-terminated string in an allocated buffer. The previous code handled this duplication incorrectly using kmemdup() and getting the length from a strlen() of the (unterminated) source string. This resulted in creating a string that continued up to the next byte in the firmware file that just happened to be 0x00.

[PATCH v5 0/4] Make headphone work on Huawei Matebook D15
by Mauro Carvalho Chehab 12 Apr '22

12 Apr '22

Huawei Matebook D15 uses two different GPIOs are used to control the output: - gpio0 controls the speaker output; - gpio1 controls the headphone output. Changing both at the same time cause spurious events that are mis-interpreted as input events, causing troubles on apps. So, a delay is needed before turning on such gpios. Also, the headset microphone is connected to MIC1, instead of MIC2 port. With this patch, plugging a headphone causes a jack event to trigger the speaker supply, powering down the speaker and powering up the headphone output. Removing the headphone also triggers the power supply, powering up the speaker and powering down the headphone. The headset microphone also works. --- v5: - dropped an uneeded differential mux from the boards driver. v4: - add support for headset microphone on MIC1 port. v3: - add a patch changing GPIO quirk speaker naming. Patch 2 got rebased on the top of it.

[PATCH 0/2] Allow detecting ACP6x DMIC via _DSD
by Mario Limonciello 12 Apr '22

12 Apr '22

It's not possible to probe for the presence of a DMIC, so the ACP6x machine driver currently has a hardcoded list of all the systems known to have a DMIC connected to the ACP. Although this design works it means that the acp6x driver needs to always grow with more systems and worse, if an OEM introduces a new system there will be a mismatch in time that even if the driver (otherwise) works fine it needs their system added to the list to work. So this series introduces a _DSD that OEMs can populate into the BIOS to indicate presence of a DMIC.
