How to install DMC firmware

Postby fred44nl » 2018-08-26 16:28

my Debian machine has a fresh install with Debian 9.0 and has been updated from time to time.
in sudo dmesg I find:
[ 3.994310] i915 0000:00:02.0: firmware: failed to load i915/bxt_dmc_ver1_07.bin (-2)


[ 3.994325] i915 0000:00:02.0: Failed to load DMC firmware [https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling runtime power management.


how much does this matter ??
if it does matter much, how do I install bxt_dmc_ver1_07.bin ??

Use this search function to find the package containing that file:

https://www.debian.org/distrib/packages#search_contents

Or do it locally (fnar!):

ok, thank you
so, bxt_dmc_ver1_07.bin should be in /lib/firmware/i915
however, I do have /lib/firmware, but there is folder i915 in there.

do I just make that folder ??
and copy bxt_dmc_ver1_07.bin in it ??
or is there an more official installation procedure ??

If you have more ????, the Debian wiki entry on firmware will answer those.
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 28.1.0, wine-staging 3.19, GIMP 2.10.8, Liquorix kernel 4.18-21, CopyQ 3.7.0

this installs a large amount of drivers, where I only need one.
is there a way to install one single driver ??
that is, apart from starting over and add the driver while installing Debian.

Firmware is not drivers. Firmware is a tiny binary file that gets loaded on the device whereas drivers are kernel modules.
That package takes a whole 7MB once installed. If you don't have 7MB to spare, you could download the package, extract the firmware and put it in /lib/firmware (I think that's where it goes from memory.)

after adding the required firmware packages, I was left with:
[ 4.992448] [drm] GuC firmware load skipped

looked for a solution and found this:
sudo nano /etc/modprobe.d/i915.conf
options i915 enable_guc_loading=1 enable_guc_submission=1


problem solved, but now my kernel is tainted.
[ 3.945069] Setting dangerous option enable_guc_loading - tainting kernel
[ 3.945074] Setting dangerous option enable_guc_submission - tainting kernel


how big a problem is this ??
is there another way to solve skipping GuC firmware ??

Not as big a problem as your apparent inability to do some basic research.

Pro tip: enter "tainted kernel linux" into a search engine and read the stackexchange link at the top of the list.

And please stop using multiple question marks, it's really irritating me.
