Intel uhd graphics 630 Running in software mode

[yama_oi]

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

[ 2.787239] 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 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.

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.

I've found this issue on Debian 10 (buster with Gnome) but: It works full 3D rendering for some hours since system boot and, after a while, it turns to software rendering mode automagically.

I've tried all solutions described in this thread (first with Debian 9, now once Debian is upgraded to buster), and now I'm also trying with Linux and all firmware from buster-backports, getting same behaviour.
Current tip when upgrading packages:

Code: Select all

update-initramfs: Generating /boot/initrd.img-5.2.0-0.bpo.3-amd64
W: Possible missing firmware /lib/firmware/i915/icl_dmc_ver1_07.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_huc_ver01_8_2893.bin for module i915


I haven't found new Mesa to upgrade at this point.

Can you install inxi and report what

Code: Select all

inxi -G

in the terminal reports when it's working fine, and then again when it's failing?

Buster's Mesa 18.3.6 supports the eighth-generation UHD 630 quite well, as does its firmware-misc-nonfree. I don't know much about the ninth-generation support, though.

I've observed now that graphics become progressively more and more slow; not from a time point.
