New subject: [PATCH 1/6] ASoC: Intel: avs: Move IPC error messages one level down

From: Cezary Rojewski cezary.rojewski@intel.com

Code size can be reduced if avs_dsp_send_xxx_msg()s take responsibility for dumping logs in case of an IPC message failure. In consequence, avs_ipc_err() helper is removed.

New subject: [PATCH 2/6] ASoC: Intel: avs: Use generic size defines

Instead of using PAGE_SIZE as base of definitions in headers, use generic size defines. While x86 platforms use 4096 as page size, there are platforms which use different page sizes. Two of changed defines are for memory windows on DSP side, which have fixed size independent of host side page size. Another one is for CLDMA buffer which also doesn't need to change with page size.

New subject: [PATCH 3/6] ASoC: Intel: avs: Preallocate memory for module configuration

In order to instantiate modules on the firmware side, the driver sends payload with module configuration. In some case size of this information is not known before hand, so driver allocates temporary memory during module creation and frees it after use. Optimize the flow a bit, by preallocating maximum buffer. This removes the time spend on allocating memory, as well as potential OOM errors during module initialization.

Handlers for modules, where configuration data fits on stack, are left as is.

New subject: [PATCH 4/6] ASoC: Intel: avs: Keep module refcount up when gathering traces

From: Cezary Rojewski cezary.rojewski@intel.com

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.

From: Wu Zhou wu.zhou@intel.com

When audio controller is passed-through to the guest machine in virtualized environment, the basefw load will fail the next time guest OS reboots. Disable the DSP main core before loading the base firmware to sanitize the environment.

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
