drm/amd/pm: Rename enable_bapm() to notify_ac_dc()

2026-05-27T14:48:11+00:00

No functional changes, just change the name of this function pointer to be more generic. BAPM refers to a specific feature on KV, but other kinds of ASICs may also need the SMU to be notified on AC/DC changes. Also remove the argument and use adev->pm.ac_power instead.

drm/amd/pm: fix race in power state check before mutex lock

2026-01-27T23:11:27+00:00

The power state check in amdgpu_dpm_set_powergating_by_smu() is done before acquiring the pm mutex, leading to a race condition where: 1. Thread A checks state and thinks no change is needed 2. Thread B acquires mutex and modifies the state 3. Thread A returns without updating state, causing inconsistency Fix this by moving the mutex lock before the power state check, ensuring atomicity of the state check and modification.

drm/amd/pm: Return -EOPNOTSUPP when can't read power limit

2026-01-21T19:22:11+00:00

So that hwmon_attributes_visible() will see that the power2_cap attributes should not be visible on GPUs that don't support the get_power_limit() function. This fixes an error when running the "sensors" command on SI.

drm/amd/pm: adjust the visibility of pp_table sysfs node

2025-11-24T17:36:12+00:00

v1: - make pp_table invisible on VF mode (only valid on BM) - make pp_table invisible on Mi* chips (Not supported) - make pp_table invisible if scpm feature is enabled. v2: move pp_table invisible code logic into amdgpu_dpm_get_pp_table() function. v3: add table buffer pointer check both on powerplay & swsmu.

drm/amdgpu: Drop PMFW RLC notifier from amdgpu_device_suspend()

2025-11-04T16:52:48+00:00

For S3 on vangogh, PMFW needs to be notified before the driver powers down RLC. This already happens in smu_disable_dpms() so drop the superfluous call in amdgpu_device_suspend().

drm/amd: Stop overloading power limit with limit type

2025-10-13T18:14:35+00:00

When passed around internally the upper 8 bits of power limit include the limit type. This is non-obvious without digging into the nuances of each function. Instead pass the limit type as an argument to all applicable layers. Reviewed-by: Lijo Lazar Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher
