drm/amd/pm: add 5s custom timeout for unload messages

2026-08-25T22:46:05+00:00

The default SMU message timeout may be too short for the PrepareMp1ForUnload message on smu_v15_0_8, leading to spurious -ETIME errors under load or slow firmware response conditions. Introduce SMU_V15_0_8_MSG_TIMEOUT_US (5 seconds) and apply it to: - smu_v15_0_8_notify_unload(): switch from smu_cmn_send_smc_msg() to smu_cmn_send_smc_msg_with_params_ext() to pass the explicit timeout. v2: Use c2pmsgctl and args directly (Lijo) Signed-off-by: Asad Kamal Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu: Remove is_idle (trivial cases)

2026-08-25T22:25:28+00:00

The is_idle method on amd_ip_funcs is never called. Remove the trivial cases where either: a) It's just a return true function that can be deleted together with the .is_init = b) The function is called somewhere else, so we just remove the assignment.

drm/amd/pm: Remove unused functions in smu_v15_0

2026-08-25T22:25:25+00:00

smu_v15_0_load_microcode() and smu_v15_0_set_single_dpm_table() are not called anywhere; the latter is a carry-over from a previous version. The static helpers smu_v15_0_get_dpm_freq_by_index(), smu_v15_0_get_dpm_level_count() and smu_v15_0_get_fine_grained_status() were only called from smu_v15_0_set_single_dpm_table(), so remove those as well. Remove all functions along with their declarations from the header.

drm/amd/pm: compute SMU v15.0.0 gpu_metrics from accumulator table

2026-08-25T22:25:25+00:00

Rework smu_v15_0_0_get_gpu_metrics() to derive values from the raw accumulator double-buffer instead of the firmware-computed SmuMetrics_t snapshot: - Add SMU_V15_IOD_AVG()/SMU_V15_CORE_AVG() helpers: wrapping_sub() delta over the sampling window, scaled by the caller's unit factor, then descaled from Q10 fixed-point with >>10 (scale before shift to keep sub-unit precision); typeof() preserves each field's width. - Reuse the same macro in smu_v15_0_0_compute_all_metrics(), dropping the open-coded div_u64(..., 1024) boilerplate. - Drop the unused smu_v15_0_0_get_gpu_metrics_table() helper and the SMU_TABLE_SMU_METRICS allocation.

drm/amd/pm: silence uninitialized variable warnings

Smatch complains that: drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu15/smu_v15_0_8_ppt.c:1964 smu_v15_0_8_set_performance_level() error: uninitialized symbol 'ret'. In this line there is an "if (ret)" condition where "ret" is either zero or uninitialized. Initialize "ret" at the start of the function to avoid a potential uninitialized variable bug. But also delete the condition since it is never true.
