drm: Mark AGP implementation and ioctls as legacy

2021-05-10T13:46:58+00:00

Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls
as legacy. Add the _legacy_ infix to all AGP functions. Move the
declarations to the public and internal legacy header files. The agp
field in struct drm_device is now located in the structure's legacy
section. Adapt drivers to the changes.

AGP code now depends on CONFIG_DRM_LEGACY.

drm/mga: drop dependency on drm_os_linux.h

2019-06-30T07:48:04+00:00

Opencode all macros used from the deprecated drm_os_linux.h header file.
The DRM_WAIT_ON used 3 * HZ as timeout.
This was translated to 3000 msec.

The return value of mga_driver_fence_wait() was not
used, so make it return void to simplify code a bit.

v2:
- fixed timeout to 3000 msec (original value was 3 * Hz)
- drop unused return value from mga_driver_fence_wait()
