[PATCH v2 0/6] ASoC: Intel: Skylake: Topology and shutdown fixes
Even though skylake-driver is going to be replaced by the avs-driver, the goal is to keep it functional on all the configurations it supports until its EOL. When comparing chrome trees against upstream skylake-driver, couple fixes pop up that are not part of upstream repository. These fixes are backed up by real bugs (issue trackers), address real problems. There is no reason for them to stay in the internal tree.
Patches 1-4 combined together address issue where the driver updates the presumably static audio format descriptions coming from the topology files through its "fixup" functions. As long as given audio format is used by a single path, nothing collides and any updates are harmless. However, when multiple paths e.g.: DMIC and HDMI1 utilize the same audio format descriptor, any updates caused by the opening of the first path, may cause the second to fail.
The 5th change from the set fixes driver hang sporadically occurring during shutdown procedure. Once HDAudio links are powered down along with the AudioDSP, the hang stops reproducing.
The last change helps survive in environments with limited/fragmented memory. While the BDL is small already, other buffers can be allocated using scatter-gather. This basically aligns the code with what the avs-driver does.
Changes in v2: - no changes to the first 5 patches - added patch that I forgot to add in v1

Without updating the index before BE copier config is filled with hardware parameters, outdated parameters are used instead.

AudioDSP cores and HDAudio links need to be turned off on shutdown to ensure no communication or data transfer occurs during the procedure.

Resign from ->alloc_dma_buf() and use snd_dma_alloc_pages() directly. For data i.e.: base firmware binary transfer, make use of SG allocation to better adapt to memory-limited environment. For BDL descriptor, given its small size this is not required.

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
