During AI training the GPU reached 109=C2=B0C and thermally throttled with the fan ph= ysically stationary throughout. ROOT CAUSE - SMU interface version mismatch (from dmesg): amdgpu 0000:2d:00.0: amdgpu: smu driver if version =3D 0x0000002e (46) amdgpu 0000:2d:00.0: amdgpu: smu fw if version =3D 0x00000032 (50) amdgpu 0000:2d:00.0: amdgpu: smu fw version =3D 0x00684b00 (104.75.0) amdgpu 0000:2d:00.0: amdgpu: SMU driver if version not matched The card firmware is 4 interface versions ahead of what the AMDGPU driver supports. As a result all fan control registers are inaccessible: - rocm-smi --setfan returns 'Not supported on this system' - sysfs pwm1 node is READ-ONLY (-r--r--r--) - fan1_enable returns 'Invalid argument' when read - GPU enters runtime power suspend under load, further suppressing fan resp= onse Confirmed on AMDGPU 6.16.6 and 6.16.13 under ROCm 7.2.1. FIX REQUIRED: The amdgpu kernel driver needs to be updated to support SMU interface versi= on 50 (0x00000032) as shipped on the R9700 (gfx1201, RDNA 4).
