On SI GPUs, the SMC needs to be aware of whether or not the VCE1 is used. The VCE1 is enabled/disabled through the DPM code.
Also print VCE clocks in amdgpu_pm_info. Users can inspect the current power state using: cat /sys/kernel/debug/dri/<card>/amdgpu_pm_info Signed-off-by: Timur Kristóf <[email protected]> Reviewed-by: Christian König <[email protected]> --- drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c b/drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c index 020e05c137e4..1f539cc65f41 100644 --- a/drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c +++ b/drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c @@ -7046,13 +7046,20 @@ static void si_set_vce_clock(struct amdgpu_device *adev, if ((old_rps->evclk != new_rps->evclk) || (old_rps->ecclk != new_rps->ecclk)) { /* Turn the clocks on when encoding, off otherwise */ + dev_dbg(adev->dev, "set VCE clocks: %u, %u\n", new_rps->evclk, new_rps->ecclk); + if (new_rps->evclk || new_rps->ecclk) { - /* Place holder for future VCE1.0 porting to amdgpu - vce_v1_0_enable_mgcg(adev, false, false);*/ + amdgpu_asic_set_vce_clocks(adev, new_rps->evclk, new_rps->ecclk); + amdgpu_device_ip_set_clockgating_state( + adev, AMD_IP_BLOCK_TYPE_VCE, AMD_CG_STATE_UNGATE); + amdgpu_device_ip_set_powergating_state( + adev, AMD_IP_BLOCK_TYPE_VCE, AMD_PG_STATE_UNGATE); } else { - /* Place holder for future VCE1.0 porting to amdgpu - vce_v1_0_enable_mgcg(adev, true, false); - amdgpu_asic_set_vce_clocks(adev, new_rps->evclk, new_rps->ecclk);*/ + amdgpu_device_ip_set_powergating_state( + adev, AMD_IP_BLOCK_TYPE_VCE, AMD_PG_STATE_GATE); + amdgpu_device_ip_set_clockgating_state( + adev, AMD_IP_BLOCK_TYPE_VCE, AMD_CG_STATE_GATE); + amdgpu_asic_set_vce_clocks(adev, 0, 0); } } } @@ -7574,6 +7581,7 @@ static void si_dpm_debugfs_print_current_performance_level(void *handle, } else { pl = &ps->performance_levels[current_index]; seq_printf(m, "uvd vclk: %d dclk: %d\n", rps->vclk, rps->dclk); + seq_printf(m, "vce evclk: %d ecclk: %d\n", rps->evclk, rps->ecclk); seq_printf(m, "power level %d sclk: %u mclk: %u vddc: %u vddci: %u pcie gen: %u\n", current_index, pl->sclk, pl->mclk, pl->vddc, pl->vddci, pl->pcie_gen + 1); } -- 2.51.0
