[PATCH 0/2] ASoC: SOF: ipc4: Take priority into cosideration when sorting pipelines
Hi,
Add pipeline priority support for IPC4: Add support for parsing pipeline priorities from the topology. This will be used to break the tie between pipelines to set the trigger order when multiple pipelines are triggered simultaneously.
Regards, Peter --- Rander Wang (2): ASoC: SOF: IPC4: get pipeline priority from topology ASoC: SOF: IPC4: sort pipeline based on priority

Driver set pipeline priority according to priority setting in topology.

The pipeline priority is set in topology and driver should sort pipeline based on priority for trigger order.

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
