Hi there, I have some troubles in enabling the low power encoding (H264) on my new 423+.
I have done the following steps, could anyone point out what is missing/wrong for me? Many thanks in advance!
(1) I have downloaded the i915 firmware from git.kernel.org (tag=20240513) and put them under
(2) I have edited the
(3) I have rebooted the machine many times, but the GuC and HuC status are null.
(4) the dmesg shows nothing about GuC and HuC also
My machine: Linux Synology423plus 4.4.302+ #69057 SMP Fri Jan 12 17:02:28 CST 2024 x86_64 GNU/Linux synology_geminilake_423+
I am using the latest 10.8.13 nyanmisaka/jellyfin pulled from container manager
==== update 2024Jun1:
I just find out that the full dmesg output contains the following two lines, which are weird since glk firmware is public available
So now the only solution is to downgrade DSM back to where the patch is not applied?

Quote:[ 34.002180] [drm] GuC: No firmware known for this platform!Then unfortunately I found a patch of intel driver kernel indicating that GuC and HuC are deliberately turned off for glk CPU because by then the firmware was not ready... https://patchwork.kernel.org/project/int...intel.com/

So now the only solution is to downgrade DSM back to where the patch is not applied?
