* drm/amdgpu: disable workload profile switching when OD is enabledAlex Deucher2025-06-031-0/+1
| | | | | | | | | | | | | Users have reported that they have to reduce the level of undervolting to acheive stability when dynamic workload profiles are enabled on GC 10.3.x. Disable dynamic workload profiles if the user has enabled OD.

* drm/amd/pm: add support for checking SDMA reset capability[email protected]2025-02-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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]>

* drm/amdgpu/UAPI: add new CTX OP to get/set stable pstatesAlex Deucher2022-01-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Add a new CTX ioctl operation to set stable pstates for profiling. When creating traces for tools like RGP or using SPM or doing performance profiling, it's required to enable a special stable profiling power state on the GPU. These profiling states set fixed clocks and disable certain other power features like powergating which may impact the results. Historically, these profiling pstates were enabled via sysfs, but this adds an interface to enable it via the CTX ioctl from the application. Since the power state is global only one application can set it at a time, so if multiple applications try and use it only the first will get it, the ioctl will return -EBUSY for others. The sysfs interface will override whatever has been set by this interface.
