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

2025-11-24T17:36:12Z

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/amd/pm/powerplay/smumgr: Fix PCIeBootLinkLevel value on Iceland

2025-10-28T13:50:31Z

Previously this was initialized with zero which represented PCIe Gen 1.0 instead of using the maximum value from the speed table which is the behaviour of all other smumgr implementations.

drm/amd: Stop overloading power limit with limit type

2025-10-13T18:14:35Z

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

drm/amd/powerplay: Fix CIK shutdown temperature

2025-10-13T18:14:15Z

Remove extra multiplication. CIK GPUs such as Hawaii appear to use PP_TABLE_V0 in which case the shutdown temperature is hardcoded in smu7_init_dpm_defaults and is already multiplied by 1000. The value was mistakenly multiplied another time by smu7_get_thermal_temperature_range.

drm/amd/pm: Use pm_display_cfg in legacy DPM (v2)

2025-09-15T20:52:46Z

This commit is necessary for DC to function well with chips that use the legacy power management code, ie. SI and KV. Communicate display information from DC to the legacy PM code. Currently DC uses pm_display_cfg to communicate power management requirements from the display code to the DPM code. However, the legacy (non-DC) code path used different fields and therefore could not take into account anything from DC. Change the legacy display code to fill the same pm_display_cfg struct as DC and use the same in the legacy DPM code. To ease review and reduce churn, this commit does not yet delete the now unneeded code, that is done in the next commit. v2: Rebase. Fix single_display in amdgpu_dpm_pick_power_state.

drm/amd/pm: use int type to store negative error codes

2025-09-05T21:38:40Z

Use int instead of uint32_t for 'ret' variable to store negative error codes or zero returned by other functions. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but can be confusing. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.

drm/amd/pm/powerplay/smumgr: remove redundant ternary operators

2025-09-05T21:38:39Z

For ternary operators in the form of "a ? true : false", if 'a' itself returns a boolean result, the ternary operator can be omitted. Remove redundant ternary operators to clean up the code. Swap variable positions on either side of '==' to enhance readability. Signed-off-by: Liao Yuanhong Signed-off-by: Alex Deucher
