[PATCH 0/3] ASoC: SOF: Intel: fix to dsp state dump trace levels
Small series that addresses a problem where DSP status dump for a failure case, ends up being printed as as debug print. This is important information for any bug report. While at it, the series contains a few cleanups to related code.
Ranjani Sridharan (3): ASoC: SOF: Intel: hda: remove duplicated status dump ASoC: SOF: modify the SOF_DBG flags ASoC: SOF: Intel: hda: fix the condition passed to sof_dev_dbg_or_err

Remove the duplicate status dump in case DSP init fails. The core will be powered down in this case and the status dump will be invalid anyway.

The SOF_DBG_* macros are used for dual purposes right now, for the sof_core_debug module parameter and for the dbg_dump() ops. So, separate these two types of flags into different types to avoid confusion.

From: Ranjani Sridharan ranjani.sridharan@linux.intel.com
The condition boot_iteration == HDA_FW_BOOT_ATTEMPTS to determine the log level for the DSP status dump would only work in the case of DSP init failure after maximum number of attempts to initialize the DSP. If DSP init succeeds in less than HDA_FW_BOOT_ATTEMPTS attempts and FW loading fails, the ROM status dump would end up getting logged as debug instead of an error.
So, add a new flag, SOF_DBG_DUMP_LOG_ERROR, to explicitly specify the log level for DSP status dump.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
