Now that the DC analog connector support and VCE1 support landed, SI dGPUs are at feature parity with the old radeon driver.
Enabling the amdgpu driver by default for SI dGPUs has the following benefits: - More stable OpenGL support through RadeonSI - Vulkan support through RADV - Improved performance - Better display features through DC Users who want to keep using the old driver can do so using: amdgpu.si_support=0 radeon.si_support=1 Signed-off-by: Timur Kristóf <[email protected]> --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 1 + drivers/gpu/drm/radeon/radeon_drv.c | 1 + 2 files changed, 2 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index 3cf36d28d27f..0539f97fa2f5 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -2327,6 +2327,7 @@ static bool amdgpu_support_enabled(struct device *dev, param = "si_support"; module_param = amdgpu_si_support; amdgpu_support_built = IS_ENABLED(CONFIG_DRM_AMDGPU_SI); + support_by_default = true; break; case CHIP_BONAIRE: diff --git a/drivers/gpu/drm/radeon/radeon_drv.c b/drivers/gpu/drm/radeon/radeon_drv.c index 40dff6feac8a..fe7ed70f4703 100644 --- a/drivers/gpu/drm/radeon/radeon_drv.c +++ b/drivers/gpu/drm/radeon/radeon_drv.c @@ -273,6 +273,7 @@ static bool radeon_support_enabled(struct device *dev, gen = "SI"; module_param = radeon_si_support; amdgpu_support_built &= IS_ENABLED(CONFIG_DRM_AMDGPU_SI); + support_by_default = false; break; case CHIP_BONAIRE: -- 2.51.1
