2024-09-27[tree-wide] finally take no_llseek outAl Viro
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

2024-05-06ASoC: Intel: avs: clarify Copyright informationPierre-Louis Bossart
For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

2023-09-29ASoC: Intel: avs: Keep module refcount up when gathering tracesCezary Rojewski
To prevent rmmod and similar behave unexpectedly when invoked on snd_soc_avs module while the AudioDSP firmware tracing is ongoing, increase the module refcount until the tracing is stopped.

2022-12-05ASoC: Intel: avs: Allow for dumping debug window snapshotCezary Rojewski
Add new read-only debugfs entry which dumps entire content of the SRAM window 2 i.e.: the debug window. Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Link: https://lore.kernel.org/r/20221202152841.672536-17-cezary.rojewski@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2022-12-05ASoC: Intel: avs: Allow for dumping FW_REGS areaCezary Rojewski
SRAM0 window begins with a block of memory, usually of size PAGE_SIZE, dedicated to the base firmware registers. When debugging firmware, it is desirable to be able to dump them at will.

2022-12-05ASoC: Intel: avs: Gather remaining logs on strace_release()Cezary Rojewski
When user closes the tracer, some logs may still remain in the tail of the buffer as firmware sends LOG_BUFFER_STATUS notification only when certain threshold of data is reached. Add whatever is left to already gathered logs so no information is lost.

2022-12-05ASoC: Intel: avs: Probing and firmware tracing over debugfsCezary Rojewski
Define debugfs subdirectory delegated for IPC communication with DSP. Input format: uint,uint,(...) which are later translated into DWORDS sequence and further into instances of struct of interest given the IPC type. For Extractor probes, following have been enabled: - PROBE_POINT_ADD (echo <..> probe_points) - PROBE_POINT_REMOVE (echo <..> probe_points_remove) - PROBE_POINT_INFO (cat probe_points) Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Link: https://lore.kernel.org/r/20221202152841.672536-14-cezary.rojewski@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2022-12-05ASoC: Intel: avs: Drop usage of debug members in non-debug codeCezary Rojewski
Switch to debug-context aware wrappers instead of accessing debug members directly allowing for readable separation of debug and non-debug related code. Duplicates are removed along the way.

2022-12-05ASoC: Intel: avs: Introduce debug-context aware helpersCezary Rojewski
Debug-related fields and log-dumping are useful when debugfs is enabled. Define them under CONFIG_DEBUG_FS and provide stubs when the config is disabled so that the code that makes use of these needs not to be complicated unnecessarily. Members that are duplicated by this patch will be removed by the follow up changes.
