From 07fecde5d3ece770234e2b71e052079af776869a Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 7 Oct 2016 12:22:02 -0400 Subject: [PATCH] drm/amdgpu: fill in vce clock info ioctl query (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Returns the vce clock table for the user mode driver. The user mode driver can fill this data into vce clock data packet for optimal VCE DPM. v2: update to the new API Reviewed-by: Rex Zhu Reviewed-by: Christian König Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c index 1ecfe9a046ab..3570124ed186 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c @@ -524,6 +524,24 @@ static int amdgpu_info_ioctl(struct drm_device *dev, void *data, struct drm_file return copy_to_user(out, &dev_info, min((size_t)size, sizeof(dev_info))) ? -EFAULT : 0; } + case AMDGPU_INFO_VCE_CLOCK_TABLE: { + unsigned i; + struct drm_amdgpu_info_vce_clock_table vce_clk_table = {}; + struct amd_vce_state *vce_state; + + for (i = 0; i < AMDGPU_VCE_CLOCK_TABLE_ENTRIES; i++) { + vce_state = amdgpu_dpm_get_vce_clock_state(adev, i); + if (vce_state) { + vce_clk_table.entries[i].sclk = vce_state->sclk; + vce_clk_table.entries[i].mclk = vce_state->mclk; + vce_clk_table.entries[i].eclk = vce_state->evclk; + vce_clk_table.num_valid_entries++; + } + } + + return copy_to_user(out, &vce_clk_table, + min((size_t)size, sizeof(vce_clk_table))) ? -EFAULT : 0; + } default: DRM_DEBUG_KMS("Invalid request %d\n", info->query); return -EINVAL; -- 2.20.1
