[PATCH v0] ASoC: rt5645: Fix errorenous cleanup order
by Lin Ma 17 May '22

17 May '22

There is a logic error when removing rt5645 device as the function rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and delete the &rt5645->btn_check_timer latter. However, since the timer handler rt5645_btn_check_callback() will re-queue the jack_detect_work, this cleanup order is buggy. That is, once the del_timer_sync in rt5645_i2c_remove is concurrently run with the rt5645_btn_check_callback, the canceled jack_detect_work will be rescheduled again, leading to possible use-after-free. This patch fix the issue by placing the del_timer_sync function before the cancel_delayed_work_sync.

This patch was tested and confirmed to work with SOF fw on MT8195 cherry board and MT8186 krabby board. changes since v8: - fix patchset 2 and 3. move "depends on MTK_ADSP_IPC" from SND_SOC_SOF_MTK_COMMON to SND_SOC_SOF_MT8195/MT8186 to prevent generating wrong config. changes since v7: - rebase to linux-next/next-22020504 - use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL in mtk-adsp-ipc.c - move mtk-adsp-ipc.c out from driver/firmware/mediatek - add user of mtk-adsp-ipc.h in patchset 2 and 3. changes since v6: - rebase to matthias.bgg/linux.git, v5.18-next/soc - Prefer "GPL" over "GPL v2" for MODULE_LICENSE changes since v5: - fix WARNING: modpost: missing MODULE_LICENSE() in drivers/mailbox /mtk-adsp-mailbox.o. Add MODULE_LICENSE in the last line. - Due to WARNING: Missing or malformed SPDX-License-Identifier tag in line 1 in checkpatch, we don't remove SPDX-License in line 1. changes since v4: - add error message for wrong mbox chan changes since v3: - rebase on v5.16-rc8 - update reviewers changes since v2: - add out tag for two memory free phases changes since v1: - add comments for mtk_adsp_ipc_send and mtk_adsp_ipc_recv - remove useless MODULE_LICENSE - change label name to out_free Allen-KH Cheng (1): ASoC: SOF: mediatek: Add ipc support for mt8195 TingHan Shen (1): firmware: mediatek: add adsp ipc protocol interface Tinghan Shen (1): ASoC: SOF: mediatek: Add mt8186 ipc support drivers/firmware/Kconfig | 9 + drivers/firmware/Makefile | 1 + drivers/firmware/mtk-adsp-ipc.c | 157 ++++++++++++++++++ .../linux/firmware/mediatek/mtk-adsp-ipc.h | 65 ++++++++ sound/soc/sof/mediatek/Kconfig | 2 + sound/soc/sof/mediatek/adsp_helper.h | 12 +- sound/soc/sof/mediatek/mt8186/mt8186-loader.c | 5 + sound/soc/sof/mediatek/mt8186/mt8186.c | 141 ++++++++++++++++ sound/soc/sof/mediatek/mt8195/mt8195.c | 138 ++++++++++++++- 9 files changed, 519 insertions(+), 11 deletions(-) create mode 100644 drivers/firmware/mtk-adsp-ipc.c create mode 100644 include/linux/firmware/mediatek/mtk-adsp-ipc.h -- 2.18.0

UCM2 configuration guide
by Peter Wedder 17 May '22

17 May '22

Hello, I have been working on an article to describe the process of writing UCM2 configuration to split multi-channel devices into smaller devices, particularly in the context of USB audio interfaces. This is a common problem with enthusiast/studio USB audio interfaces and it happens to be a pet peeve of mine. I recently contributed a profile for the Behringer UMC204HD (https://github.com/alsa-project/alsa-ucm-conf/pull/128) and found the process to be a little intimidating, but with a lot of help from Perexg I managed to get it working. I would like to help other potential contributors out by explaining the process step by step. I was considering posting the article to the Fedora Magazine (https://fedoramagazine.org/), since that's the distro I use. However, I wanted to check with you, the ALSA maintainers, first, because the intent of the article is to encourage readers to contribute UCM configurations for their own cards, and I thought perhaps a potential surge of contributions is not something you want at the moment. Let me know what you think -- is this a welcome idea or should I forget it? I have a draft of the article available here: https://gist.github.com/brndd/ccec98a575f7c0422d50402937439227 Thanks, Peter Wedder

[PATCH] selftests: alsa: Better error messages
by Siddh Raman Pant 16 May '22

16 May '22

This allows for potentially better machine-parsing due to an expected / fixed format. Also because of eyecandy reasons. Whenever possible, errors will start with the name of the offending card/control, separated by the error with colons. Whenever there is a description of an error given, the generated error string from snd_strerror will be (mostly) enclosed in parentheses at the end. Clarity of error messages have been (hopefully) improved.
