Move the DRM buddy allocator one level up so that it can be used by GPU drivers (example, nova-core) that have usecases other than DRM (such as VFIO vGPU support). Modify the API, structures and Kconfigs to use "gpu_buddy" terminology. Adapt the drivers and tests to use the new API. The commit cannot be split due to bisectability, however no functional change is intended. Verified by running K-UNIT tests and build tested various configurations. Signed-off-by: Joel Fernandes <joelagnelf@nvidia.com> Reviewed-by: Dave Airlie <airlied@redhat.com> [airlied: I've split this into two so git can find copies easier. I've also just nuked drm_random library, that stuff needs to be done elsewhere and only the buddy tests seem to be using it]. Signed-off-by: Dave Airlie <airlied@redhat.com>

This enables access to the EDID transferred from the firmware.
|
|
On x86, this is from the VESA BIOS. DRM display drivers will
|
|
be able to export the information to userspace.
|
|
|
|
Also enable this if DDC/I2C transfers do not work for your driver
|
|
and if you are using nvidiafb, i810fb or savagefb.
|
|
|
|
In general, choosing Y for this option is safe. If you
|
|
experience extremely long delays while booting before you get
|
|
something on your display, try setting this to N. Matrox cards in
|
|
combination with certain motherboards and monitors are known to
|
|
suffer from this problem.
