--- Comment #29 from Christian König (christian.koenig@amd.com) ---
For this you need to call the driver IOCTL to create a buffer object directly.
Best is probably you use the Mesa code as and work from that backward, see here
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/winsys/radeon/drm/radeon_drm_bo.c
function radeon_create_bo.
drmCommandWriteRead(), struct drm_radeon_gem_create and all the defines you
need are provided by libdrm.
Domain should be RADEON_DOMAIN_GTT in this case, flags can be zero or
RADEON_GEM_GTT_WC.
Size and alignment should be obvious.
