Bad magic error when loading SOF firmware
by David Sayada 04 May '23

04 May '23

Hello SOF team, We are trying to evaluate the SOF project on our 8MPLUSSLPD4-EVK based product, and we are getting some issues when trying to run one of the "yocto compiled" SOF Firmware. Below is the procedure we are trying to perform: *echo /lib/firmware/imx/sof/sof-imx8m.ri > /sys/class/remoteproc/remoteproc0/firmware* *echo start > /sys/class/remoteproc/remoteproc0/state* We are getting, at the end, a "Image is corrupted (bad magic)" -22 return code. We have also created a VM (based on SOF 2.4.1) where we can compile (and sign, with default keys) the different toolchains and firmwares. Will that help in having a firmware run correctly? Maybe, we are doing incorrect things, if this is the case, please advise. Best regards, David Sayada.

[PATCH] ASoC: SOF: Intel: hda-stream: Move three variable assignments behind condition checks in hda_dsp_iccmax_stream_hw_params()
by Markus Elfring 24 Apr '23

24 Apr '23

Date: Wed, 19 Apr 2023 20:42:19 +0200 The address of a data structure member was determined before a corresponding null pointer check in the implementation of the function “hda_dsp_iccmax_stream_hw_params”. Thus avoid the risk for undefined behaviour by moving the assignment for three local variables behind some condition checks. This issue was detected by using the Coccinelle software.

[PATCH v2 00/13] ASoC: add and use asoc_dummy_dlc
by Kuninori Morimoto 24 Apr '23

24 Apr '23

Hi Mark These are v2 patch-set of asoc_dummy_dlc. Many ASoC drivers are using dummy DAI. I have 2 concern about it. 1st one is there is no guarantee that local strings ("snd-soc-dummy-dai", "snd-soc-dummy") are kept until the card was binded if it was added at subfunction. 2nd one is we can use common snd_soc_dai_link_component for it. This patch-set adds common asoc_dummy_dlc, and use it. v1 -> v2 - Separate intel patch into 3 - Topology codec doesn't use asoc_dummy_dlc Link: https://lore.kernel.org/r/874jpe3uqh.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (13): ASoC: soc-utils.c: add asoc_dummy_dlc ASoC: ti: use asoc_dummy_dlc ASoC: sof: use asoc_dummy_dlc ASoC: amd: use asoc_dummy_dlc ASoC: fsl: use asoc_dummy_dlc ASoC: qcom: use asoc_dummy_dlc ASoC: atmel: use asoc_dummy_dlc ASoC: meson: use asoc_dummy_dlc ASoC: intel: avs: use asoc_dummy_dlc ASoC: intel: sof: use asoc_dummy_dlc ASoC: intel: skylake: use asoc_dummy_dlc ASoC: simple_card_utils.c: use asoc_dummy_dlc ASoC: soc-topology.c: add comment for Platform/Codec include/sound/simple_card_utils.h | 1 - include/sound/soc.h | 1 + sound/soc/amd/acp/acp-mach-common.c | 43 ++++++++------------ sound/soc/atmel/atmel-classd.c | 8 ++-- sound/soc/atmel/atmel-pdmic.c | 8 ++-- sound/soc/fsl/imx-audmix.c | 14 +++---- sound/soc/fsl/imx-card.c | 11 +---- sound/soc/fsl/imx-rpmsg.c | 3 +- sound/soc/fsl/imx-spdif.c | 8 ++-- sound/soc/generic/simple-card-utils.c | 9 +--- sound/soc/intel/avs/boards/i2s_test.c | 6 +-- sound/soc/intel/boards/ehl_rt5660.c | 8 +--- sound/soc/intel/boards/skl_hda_dsp_generic.c | 8 +--- sound/soc/intel/boards/sof_cs42l42.c | 11 +---- sound/soc/intel/boards/sof_es8336.c | 11 +---- sound/soc/intel/boards/sof_nau8825.c | 11 +---- sound/soc/intel/boards/sof_pcm512x.c | 3 +- sound/soc/intel/boards/sof_rt5682.c | 14 ++----- sound/soc/intel/boards/sof_sdw.c | 13 +----- sound/soc/intel/boards/sof_ssp_amp.c | 18 +++----- sound/soc/meson/axg-card.c | 8 ++-- sound/soc/meson/meson-card-utils.c | 10 +---- sound/soc/qcom/common.c | 11 +---- sound/soc/soc-topology.c | 22 +++++----- sound/soc/soc-utils.c | 7 ++++ sound/soc/sof/nocodec.c | 8 ++-- sound/soc/ti/omap-hdmi.c | 8 ++-- 27 files changed, 89 insertions(+), 194 deletions(-) -- 2.25.1

[PATCH] ASoC: SOF: topology: Move a variable assignment behind condition checks in sof_dai_load()

[PATCH 1/6] ASoC: SOF: amd: remove unused code
by Vijendar Mukunda 03 Apr '23

03 Apr '23

During initial SOF driver bring up on AMD platforms, only DMIC support was added. As of today, we have a complete SOF solution for I2S endpoints along with DMIC endpoint. This code is no longer required. Remove unused code from RMB and RN platform ACP PCI driver.
