Intel uhd graphics 630 Running in software mode

Postby yama_oi » 2018-08-29 06:36

Hi!
Using Strectch and motherboard with onboard graphics "Intel uhd graphics 630" which is "Running in software mode".
I have updated to 4.17.0-0.bpo.1-amd64.
Put kbl_dmc_ver1_04.bin in /lib/firmware/i915
But graphics still runs in software mode.

dmsg | grep i915 returns "DMC firmware has wrong CCS header length"

How can fixit so graphics wont run in software mode?

Thanx in advance
Moi

OK. So I have tested following:
1) added backport nonfree and install nonfree firmware.
Result: dmesg | grep i915
[ 2.442663] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem
[ 2.496345] i915 0000:00:02.0: firmware: direct-loading firmware i915/kbl_dmc_ver1_04.bin
[ 2.496607] [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4)
[ 2.720538] [drm] Initialized i915 1.6.0 20180308 for 0000:00:02.0 on minor 0
[ 2.721944] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])
[ 2.787239] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device

Still running graphics in software mode.

2) added i915.alpha_support=1 to /etc/defaults/grub.
Result: Still running graphics in software mode.

Try the firmware from sid, it's been updated recently:

I suffer from depression and may lash out occasionally, try not to take it personally.

I have the same Intel GPU--you have new 2018 eighth-generation Coffee Lake hardware, so you also need to upgrade the Mesa libraries from the backports repository. Stretch's 2016 Mesa is too old to support 2018 hardware. If you encounter bugs with the default modesetting driver that you'll then be assigned, any Debian version of the xserver-xorg-video-intel "intel" "i915" driver is still too old and buggy with that hardware, but I'm happy using a newer version of that dating from last month.

So you need the firmware, a kernel, and the Mesa stack from stretch-backports.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Quod Libet 4.2.0, Pale Moon 28.2.0, wine-staging 3.20, GIMP 2.10.8, Liquorix kernel 4.18-22, Midori 6.0

Got it to work, did the mesa upgrade! No more software rendering!
Thanks

Did you get va-api video hardware decoding acceleration working with it? I'm under the impression that we need an ffmpeg compiled with the newer libva in backports, then the video players like VLC, mpv, kodi, and qmplay2 need to be rebuilt against the newer mesa and ffmpeg.

When I have it working, I can play a 4K sample h.264 movie trailer, and the CPU never budges from its lowest speed setting.
