[PATCH 0/5] ASoC: SOF: client-probes: Add support for IPC4
Hi,
The probes (the ability of probing the audio data from firmware processing points or to receive stream of debug/trace information) is supported by IPC4 as well, but due to the differences between the two IPC version the low level setup and information we need for probing is different.
This series will extend the existing probes support for IPC3 with IPC4 'backend'
Regards, Peter --- Jyri Sarha (5): ASoC: SOF: probes: Replace [0] union members with DECLARE_FLEX_ARRAY() ASoC: SOF: probes: Separate IPC3 operations to a separate file ASoC: SOF: client: Add sof_client_ipc_set_get_data() ASoC: SOF: client: Add sof_client_ipc4_find_module() function ASoC: SOF: IPC4: probes: Implement IPC4 ops for probes client device

The probes (the ability of probing the audio data from firmware processing points or to receive stream of debug/trace information) is supported by IPC4 as well, but due to the differences between the two IPC version the low level setup and information we need for probing is different.
This series will extend the existing probes support for IPC3 with IPC4 'backend'

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
