drm/radeon: precompute fence cpu/gpu addr once v3
Add a start fence driver helper function which will be call once for each ring and will compute cpu/gpu addr for fence depending on wether to use wb buffer or scratch reg. This patch replace initialize fence driver separately which was broken in regard of GPU lockup. The fence list for created, emited, signaled must be initialize once and only from the asic init callback not from the startup call back which is call from the gpu reset. v2: With this in place we no longer need to know the number of rings in fence_driver_init, also writing to the scratch reg before knowing its offset is a bad idea. v3: rebase on top of change to previous patch in the serie Signed-off-by: Christian König <deathsimple@vodafone.de> Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
