2024-10-15drm/amdgpu/swsmu: add automatic parameter to set_soft_freq_rangeAlex Deucher1-1/+2
On chips that support it, you can specificy 0 and 0xffff for min and max and the PMFW will use that to determine the optimal min and max. This enables optimal performance when the user manually switches between performance levels using sysfs. Previously we'd set soft min/max which could limit performance.

This uses more aggressive hueristics than the the bootup default profile. On windows the OS has a special fullscreen 3D mode where this is used.

2024-07-10drm/amd/pm: Ignore initial value in smu response registerDanijel Slivka1-0/+2
Why: If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver load or driver unload, subsequent amdgpu driver load will fail at smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean environment is 0x1 and if value differs from expected, amdgpu driver load will fail. How to fix: Ignore the initial value in smu response register before the first smu message is sent,if smc in SMU_FW_INIT state, just proceed further to send the message. If register holds an unexpected value after smu message was sent set, smc_state to SMU_FW_HANG state and no further smu messages will be sent. v2: Set SMU_FW_INIT state at the start of smu hw_init/resume. Check smc_fw_state before sending smu message if in hang state skip sending message.
