Package: firmware-amd-graphics Version: 20230515-3 Severity: important Tags: upstream Forwarded: https://gitlab.freedesktop.org/drm/amd/-/issues/1887 X-Debbugs-Cc: onit...@gmail.com
Dear Maintainer, The current AMDGPU firmware in Debian has compatibility issues with 6.3+ kernels. These errors manifest themselves with kernel messages like these: [ +0.226777] [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3 [ +4.020959] [drm:dc_dmub_setup_subvp_dmub_command [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3 Furthermore, they cause sudden display freezes and even GPU lock-ups that require power-cycling the system. It's not clear why these problems occur, but they might have to do with certain optimizations that AMD had to do to reduce power consumption at idle on RX 7000 series GPUs. See https://gitlab.freedesktop.org/drm/amd/-/issues/2315 for more information about this issue. As a temporary workaround, it's possible to avoid the power management optimizations by reducing the overall pixel clock rate or creating modelines with a longer blanking delay, as long as the display supports this. For example, reducing the refresh rate from 120Hz to 60Hz has helped in one case for me. Another workaround is to disable optimizations in the affected firmware with the kernel option drm.vblankoffdelay=0 . As stated in https://gitlab.freedesktop.org/drm/amd/-/issues/1887#note_1993615 , the problematic firmware changes were reverted in https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=d3f66064cf43bd7338a79174bd0ff60c4ecbdf6d , and there have been several amdgpu firmware commits since. Please update linux-firmware as soon a release containing the revert or a permanent fix is available. Thanks. -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-debug'), (500, 'proposed-updates-debug'), (300, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.4.0-1-amd64 (SMP w/24 CPU threads; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled firmware-amd-graphics depends on no packages. firmware-amd-graphics recommends no packages.
