Growing number of distro started to package linux-firmware with zstd compression. Signed-off-by: Peter Ujfalusi <[email protected]>
With the 6.7.0-rc2 update preparation with the sof-kconfig generated config
we lost HDMI audio on all platforms.
It turned out that the reason for it is that DRM_FBDEV_EMULATION is no
longer enabled.
See the following commits:
bb6c4507fe82 ("drm: fix up fbdev Kconfig defaults")
a5ae331edb02b ("drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION")
701d2054fa317 ("fbdev: Make support for userspace interfaces configurable")
and possibly more.
The connection is not clear, but we cannot afford to loose HDMI audio.

@plbossart, yes, it looks odd, you can try it with thesofproject/linux#4717
I have reached out to the i915 guys, I think it will go down to create an issue in their gitlab place (need to create account and stuff).

In any case, without this change we cannot move to 6.7.0 base for now.
