[DNM] dai: add support for Intel UAOL DAI #9227

tlissows · 2024-06-14T07:44:28Z

This adds support for Intel USB Audio Offload Link (UAOL) DAI.

This PR needs another (Zephyr) PR drivers: dai: add DAI driver for Intel UAOL to be merged first.

Not following the directions, this doesn't seem aligned with what we previously did for ALH / SoundWire.

I don't fully understand this.

for LNL+ all the DMA stuff is handled in the same way with an HDaudio-based solution.

We just moved some of the ALH stuff into the HDaudio prodessing - see line 94 the test for ALH.

so shouldn't the UAOL stuff also be moved under the HDAudio category? Why special case what looks identical?

my comment still stands.

@tlissows any update here ?

plbossart

we really need to make UAOL support dependent on a version of silicon (pick one), e.g. ACE2.0, and not add code that will never be used on previous generations.

There's really no point in supporting anything older than ACE2.0?

@tlissows ping ?

Currently, the dai_set_config() function is called with copier gateway config data passed but without the config length, possibly making the config not parsable for some DAI drivers. This patch adds passing of the full ipc4_copier_gateway_cfg structure, giving DAI drivers the ability to access config length if needed. Signed-off-by: Tomasz Lissowski <[email protected]>

Add strict use of dai_type enum items as a call parameter for dai_get_device() function. Currently, both the dai_type and sof_ipc_dai_type items are used inconsistently. Signed-off-by: Tomasz Lissowski <[email protected]>

Removed support for ACE1.x platform from this PR. Also aligned to the changes introduced by PR basefw: Add handling of IPC4_DMA_CONTROL messages.

@tlissows I assume still undergoing testing hence the DNM ? Pls also respond to open from @plbossart

Do we need the void* cast here or is the compiler throwing up a warning in this case ? cfg_params is also const too.

@tlissows any update here ?

I have no remarks regarding the code, but I would like to see that the whole thing passes through CI. There is a temporary commit missing here that would indicate the Zephyr version from your second pull request:

@tlissows @tmleman it looks like this is good to go once it passes CI - I think @plbossart comments have now been addressed. Are we blocking on any Zephyr PRs before we can merge ?
