Bug#920454: linux-image-4.20.0-trunk-amd64: please reenable amdgpu HSA support
Package: src:linux
Version: 4.20-1~exp1
Severity: normal
The 4.20-1~exp1 configuration disabled CONFIG_HSA_AMD, necessary for using AMD's ROCm platform:
$ xzgrep CONFIG_HSA_AMD /usr/src/linux-config-4.20/config.amd64_none_amd64.xz
# CONFIG_HSA_AMD is not set
$ xzgrep CONFIG_HSA_AMD /usr/src/linux-config-4.19/config.amd64_none_amd64.xz
CONFIG_HSA_AMD=m
This was very likely unintentionally caused by 4.20 merging amdkfd into the amdgpu module
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=04d5e2765802241b54ee93d1e655123c39fa7385)
which turned the HSA_AMD config option into a bool affecting the amdgpu module.
