Bug#847570: linux-image-4.9.0-rc8-amd64-unsigned: AMDGPU not build with support for GCN1.0 and GCN1.1 VGAs
Package: linux-image-4.9.0-rc8-amd64-unsigned
Version: 4.9~rc8-1~exp1
Severity: wishlist
Tags: patch
Dear Maintainer,
I have an AMD Radeon R9 270X and I'd like to use the new amdgpu driver with it.
Since 4.9, linux includes experimental support for GCN 1.0 VGAs, but it's not
enabled in the debian builds as well as the support for GCN 1.1 cards (which
isn't new in the kernel anymore). In the kernel build config, you just need to
set CONFIG_DRM_AMDGPU_SI=Y (for GCN1.0-based cards) and CONFIG_DRM_AMDGPU_CIK=Y
(for GCN1.1-based cards). To use amdgpu if it is built into the kernel with the
old gpus users just need to blacklist radeon and upon the next reboot linux
will load amdgpu and users can install amdgpu-pro if they want to or just stick
with the newest free graphics driver.
The kernel in my system info below is built from source with the options
mentioned above enabled.
