| | | | | | | Not too certain on memory clock yet, but it gets the right numbers for each perflvl on my NVC0. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that MI_FLUSH would flush the TLBs in addition to the rest of the caches indicated in the MI_FLUSH command. However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL.
