The context save functionality with IPC4 is triggered by sending a message to the firmware about the pending power down of the primary core by the host.
In order to have this functionality implemented in a clean way we need to introduce a new IPC level PM ops for core state management and use that instead of open coding IPC messages here and there.

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
