Subject: [PATCH 0/3] Deferr load of radeon/amdgpu until amdkfd is loaded
Date: Sun, 14 Feb 2016 11:16:52 +0200 [thread overview]
Message-ID: <1455441415-16901-1-git-send-email-oded.gabbay@gmail.com> (raw)
Following Daniel's request, I spent some time removing the hard requirement
that radeon and amdgpu will always appear _after_ amdkfd in the drm Makefile.
This was done by modifing radeon/amdgpu to defer their loading if they detect
that amdkfd is not loaded yet, in case the drivers are built inside the
kernel image.
See the patch's individiual commit messages for more explanation.
This patch-set was tested on a KAVERI machine, with multiple configurations:
1. radeon + amdgpu (CIK disabled) + amdkfd as kernel modules
2. radeon + amdgpu (CIK disabled) + amdkfd inside the kernel image
3. amdgpu (CIK enabled) + amdkfd inside the kernel image (radeon not compiled)
4. amdgpu (CIK enabled) inside the kernel image (radeon + amdkfd not compiled)
5. radeon + amdgpu (CIK disabled) as kernel modules (amdkfd not compiled)
Thanks,
Oded
