* drm/amd/pm: Add support to set min ISP clocksPratap Nirujogi2025-06-241-10/+4
| | | | | | | | | | | | | | | | | | | Add support to set ISP clocks for SMU v14.0.0. ISP driver uses amdgpu_dpm_set_soft_freq_range() API to set clocks via SMU interface than communicating with PMFW directly. amdgpu_dpm_set_soft_freq_range() is updated to take in any pp_clock_type than limiting to support only PP_SCLK to allow ISP and other driver modules to set the min/max clocks. Any clock specific restrictions are expected to be taken care in SOC specific SMU implementations instead of generic amdgpu_dpm and amdgpu_smu interfaces.

* drm/amd/pm: add support for checking SDMA reset capability[email protected]2025-02-251-0/+23
| | | | | | | | | | | | | | | | | | | | | | | This patch introduces a new function to check if the SMU supports resetting the SDMA engine. This capability check ensures that the driver does not attempt to reset the SDMA engine on hardware that does not support it. The following changes are included: - New function `amdgpu_dpm_reset_sdma_is_supported` to check SDMA reset support at the AMDGPU driver level. - New function `smu_reset_sdma_is_supported` to check SDMA reset support at the SMU level. - Implementation of `smu_v13_0_6_reset_sdma_is_supported` for the specific SMU version v13.0.6. - Updated `smu_v13_0_6_reset_sdma` to use the new capability check before attempting to reset the SDMA engine. v2: change smu_reset_sdma_is_supported type to bool (Tim) Signed-off-by: Vitaly Prosyak <[email protected]> Signed-off-by: Jesse Zhang <[email protected]> Reviewed-by: Tim Huang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

But on their calling path, amdgpu_display_bandwidth_update will be called and thus its sub functions amdgpu_dpm_get_sclk/mclk. They will then try to acquire the same adev->pm.mutex and deadlock will occur. By placing amdgpu_display_bandwidth_update outside of adev->pm.mutex protection(considering logically they do not need such protection) and restructuring the call flow accordingly, we can eliminate the deadlock issue.
