Now that DC supports external DP bridge encoders, it has reached feature parity with the legacy non-DC display driver on CIK APUs: Kaveri, Kabini, Mullins.
Use the DC display driver by default on SI dGPUs, unless it is explicitly disabled using the amdgpu.dc=0 module parameter. DC brings proper support for DP/HDMI audio, DP MST, VRR, 10-bit colors, some HDR features, atomic modesetting, etc. Signed-off-by: Timur Kristóf <[email protected]> --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 11 ----------- 1 file changed, 11 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c index 362ab2b34498..fc4656a23158 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -4113,17 +4113,6 @@ bool amdgpu_device_asic_has_dc_support(struct pci_dev *pdev, case CHIP_VERDE: case CHIP_OLAND: return amdgpu_dc != 0 && IS_ENABLED(CONFIG_DRM_AMD_DC_SI); - case CHIP_KAVERI: - case CHIP_KABINI: - case CHIP_MULLINS: - /* - * We have systems in the wild with these ASICs that require - * TRAVIS and NUTMEG support which is not supported with DC. - * - * Fallback to the non-DC driver here by default so as not to - * cause regressions. - */ - return amdgpu_dc > 0; default: return amdgpu_dc != 0; #else -- 2.52.0
