Thanks for having a try. > ➜ ~ sudo python Downloads/psr.py > DRI device 0 DMCUB F/W version: 0x0400003c > ○ PSR 2 with Y coordinates (eDP 1.4a) [3] > ○ Sink OUI: Parade > ○ resv_40f: 01 > ○ ID String: 08-03 > ○ PSR Status: 00-00-02 You do have an affected panel, and if the system isn't freezing this shows that the updated firmware worked. The version you tested ( 0x0400003c ) is a little newer than I suggested ( 0x400003a ) but that's fine. The fix carries forward. > BOOT_IMAGE=/boot/vmlinuz-6.4.0-060400-generic root=UUID=41d8f993-282a-48a5-b355-6f537a3a17ab ro quiet splash amdgpu.dcdebugmask=0x0 vt.handoff=7 Good; you don't have PSR manually disabled. > Jul 3 19:45:50 rct14s kernel: [ 1001.214638] WARNING: CPU: 3 PID: 237 at drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dmub_psr.c:126 dmub_psr_get_state+0xcc/0xe0 [amdgpu] This warning we're tracking at https://gitlab.freedesktop.org/drm/amd/-/issues/2645 ** Bug watch added: gitlab.freedesktop.org/drm/amd/-/issues #2645 https://gitlab.freedesktop.org/drm/amd/-/issues/2645 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2024774 Title: AMD Rembrandt / Phoenix PSR-SU related freezes Status in Linux Firmware: New Status in linux-firmware package in Ubuntu: Fix Released Status in linux-firmware source package in Jammy: Confirmed Status in linux-firmware source package in Lunar: Confirmed Status in linux-firmware source package in Mantic: Fix Released Bug description: [ Impact ] When using kernel 6.2 or later AMD has enabled PSR selective update (PSR-SU). After a non-deterministic amount of time the system may hang with a message like this in the logs: "[amdgpu 0000:67:00.0: [drm] *ERROR* [CONNECTOR:78:eDP-1] commit wait timed out]" Affects users of laptops that contain: * AMD Rembrandt (Yellow Carp) or AMD Phoenix (Pink Sardine) chips * eDP panels with Parade TCONs (8-03 and 8-01 both reported to fail) [ Test Plan ] * Test an affected laptop with the newer firmware and ensure that PSR-SU function can be enabled and system is stable. * Ensure other functions such as hotplugging monitors and suspending continue to work. [ Where problems could occur ] * Affected firmware only is loaded on Rembrandt and Phoenix laptops. Problems would be localized to these machines. [ Other Info ] The minimum firmware needed to help these hangs: * Rembrandt: 0x400003a or later * Phoenix: 0x8001000 or later The following commit upgrades the firmware for Rembrandt (amdgpu/yellow_carp_dmcub.bin) to 0x400003c: 9dbd8ec2 ("amdgpu: DMCUB updates for various AMDGPU asics") The following commit upgrades the firmware for Phoenix (amdgpu/dcn_3_1_4_dmcub.bin) to 0x8001a00: 045b2136 ("amdgpu: update DMCUB to v0.0.172.0 for various AMDGPU ASICs") The TCON in a given laptop can be identified from the DPCD with this script: https://gitlab.freedesktop.org/drm/amd/-/blob/master/scripts/psr.py To manage notifications about this bug go to: https://bugs.launchpad.net/linux-firmware/+bug/2024774/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
