** Description changed: - The DCN 3.5 microcode in noble is out of sync with the DCN 3.6 microcode - version. + [ Impact ] - Here is an extraction of the - ╰─❯ ~/src/drm.amd/scripts/get_amdgpu_fw_version.py /tmp/here/lib/firmware/amdgpu/dcn_3_6_dmcub.bin.zst | grep ucode_version - ucode_version = 151011072 (0x9003f00) - ╰─❯ ~/src/drm.amd/scripts/get_amdgpu_fw_version.py /tmp/here/lib/firmware/amdgpu/dcn_3_5_dmcub.bin.zst | grep ucode_version - ucode_version = 150998272 (0x9000d00) + On Strix Halo platforms with an AMD R7 CPU, systems can fail to reboot + after moving to the 7.0 kernel because the DCN 3.5 DMCUB microcode was + not updated. - Since upgrading to to 7.0 kernel in noble this is causing problems where - DCN microcode doesn't load anymore for systems with DCN 3.5. Systems - with DCN 3.6 are fine. + [ Fix ] - Please sync them up (They're synced in resolute - both are 0x9003f00). + Update the DCN 3.5 and DCN 3.5.1 DMCUB firmware in two steps: + + Update to firmware version 0.1.50.0, which is required as the + predecessor for the next update. + Update to firmware version 0.1.51.0, which includes a fix for Replay + HUBP blank ordering with the DPG pending check. + DCN 3.6 firmware is intentionally excluded because Noble already + contains the same or newer payload. + + [ Test Plan ] + + Boot a Strix Halo system with an AMD R7 CPU using the updated + linux-firmware package. Reboot the system and verify that it completes + successfully. + + Manual reboot and suspend tests passed with an A400 system, AMD R7 CPU, + BIOS 2.1.2, and the test firmware. + + [ Were problems could occur ] + + The change updates binary DMCUB firmware for DCN 3.5 and DCN 3.5.1 + display hardware. A regression could affect display initialization, + reboot, suspend/resume, or display output on systems using these ASICs.
