drm-next-4.15-dc log
Hardware is a new laptops that has the AMD Bristol Ridge chipset with this SoC:
AMD A10-9620P RADEON R5, 10 COMPUTE CORES 4C+6G
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Device 9874 (rev ca)
03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 699f
(rev ff)
I tried the DC support using the
https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.15-dc branch and
the firmware from https://people.freedesktop.org/~agd5f/radeon_ucode/polaris/
but I keep having no audio at all for HDMI.
In attachment the log.
The only way to have the DC and the HDMI audio output working is by using the
branch https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-4.13 and
reverting both
https://lists.freedesktop.org/archives/amd-gfx/2017-May/009720.html and
https://cgit.freedesktop.org/~agd5f/linux/commit/?id=8f5ed2ed31944eea5c2746ec66417afac043eabd
(the first one to have the HDMI output working at all, the second one to have
the audio working fine).
Any idea?
