| * drm/amd/pm: Remove remainder of mode2_reset_is_supportDr. David Alan Gilbert2025-05-134-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch removed smu_mode2_reset_is_support() which was the only function to call through the mode2_reset_is_support() method pointer. Remove the remaining functions that were assigned to it and the pointer itself. See discussion at: https://lore.kernel.org/all/DM4PR12MB5165D85BD85BC8FC8BF7A3B48E88A@DM4PR12MB5165.namprd12.prod.outlook.com/ Signed-off-by: Dr. David Alan Gilbert <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The amdgpu_set_thermal_throttling_logging() function directly accesses the ratelimit_state structure's ->missed field, which works, but which also makes it more difficult to change this field. Therefore, make use of the ratelimit_state_reset_interval() function instead of directly accessing the ->missed field. Nevertheless, open-coded use of ->burst and ->interval is still permitted, for example, for runtime sysfs adjustment of these fields.

* drm/amdgpu/pm: Handle SCLK offset correctly in overdrive for smu 14.0.2Tomasz Pakuła2025-03-181-41/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, it seems like the code was carried over from RDNA3 because it assumes two possible values to set. RDNA4, instead of having: 0: min SCLK 1: max SCLK only has 0: SCLK offset This change makes it so it only reports current offset value instead of showing possible min/max values and their indices. Moreover, it now only accepts the offset as a value, without the indice index. Additionally, the lower bound was printed as %u by mistake. Old: OD_SCLK_OFFSET: 0: -500Mhz 1: 1000Mhz OD_MCLK: 0: 97Mhz 1: 1259MHz OD_VDDGFX_OFFSET: 0mV OD_RANGE: SCLK_OFFSET: -500Mhz 1000Mhz MCLK: 97Mhz 1500Mhz VDDGFX_OFFSET: -200mv 0mv New: OD_SCLK_OFFSET: 0Mhz OD_MCLK: 0: 97Mhz 1: 1259MHz OD_VDDGFX_OFFSET: 0mV OD_RANGE: SCLK_OFFSET: -500Mhz 1000Mhz MCLK: 97Mhz 1500Mhz VDDGFX_OFFSET: -200mv 0mv Setting this offset: Old: "s 1 <offset>" New: "s <offset>" Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4036 Reviewed-by: Yang Wang <[email protected]> Signed-off-by: Tomasz Pakuła <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
