ASoC: SOF: loader: release_firmware() on load failure to avoid batching

2021-10-17T08:43:32+00:00

[ Upstream commit 8a8e1813ffc35111fc0b6db49968ceb0e1615ced ] Invoke release_firmware() when the firmware fails to boot in sof_probe_continue(). The request_firmware() framework must be informed of failures in sof_probe_continue() otherwise its internal "batching" feature (different from caching) cached the firmware image forever. Attempts to correct the file in /lib/firmware/ were then silently and confusingly ignored until the next reboot. Unloading the drivers did not help because from their disconnected perspective the firmware had failed so there was nothing to release. Also leverage the new snd_sof_fw_unload() function to simplify the snd_sof_device_remove() function.

ASoC: SOF: loader: handle all SOF_IPC_EXT types

2020-10-23T17:28:52+00:00

Do not emit a warning for extended firmware header fields that are not used by kernel. This creates unnecessary noise to kernel logs like: sof-audio-pci 0000:00:1f.3: warning: unknown ext header type 3 size 0x1c sof-audio-pci 0000:00:1f.3: warning: unknown ext header type 4 size 0x10 Signed-off-by: Bard Liao Reviewed-by: Pierre-Louis Bossart Reviewed-by: Ranjani Sridharan Reviewed-by: Guennadi Liakhovetski Signed-off-by: Kai Vehmanen Link: https://lore.kernel.org/r/20201021182419.1160391-1-kai.vehmanen@linux.intel.com Signed-off-by: Mark Brown

ASoC: SOF: loader: Add debug box region

2020-08-26T11:44:09+00:00

This patch adds an IPC initiated debug box region in the snd_sof_dev structure, defined in soc/sof/sof-priv.h. It is initialized at loading, in the sof_get_windows function from soc/sof/loader.c, in a similar manner with the stream box and host box. This region is useful because the firmware will put an error message here so the kernel can read it in case of a dsp oops.

ASoC: SOF: IPC: make sof_ipc_window monosized

2020-08-26T11:44:07+00:00

This step is needed to add possibility to pack sof_ipc_window inside another one in used FW build tools - for example in extended manifest. Structure reusability leads to easy parsing function reuse, so source code is shorter and easier to maintain. Using structures with constant size is less tricky and properly supported by each toolchain by contrast to variable size elements. This is minor ABI change - backward compatibility is kept.

ASoC: SOF: Introduce extended manifest

2020-05-25T13:59:34+00:00

Extended manifest is a place to store build time known firmware metadata, for example firmware version or used compiler description. Given information is read on host side before firmware startup. This part of output binary is located as a first structure in binary file. Extended manifest should be skipped in firmware loading routine.
