  To: intel-gfx; +Cc: Lucas De Marchi, Matt Roper, dri-devel

From: Fei Yang <fei.yang@intel.com>

On MTL, GT can no longer allocate on LLC - only the CPU can.
This, along with addition of support for ADM/L4 cache calls a
MOCS/PAT table update.
Also add PTE encode functions for MTL as it has different PAT
index definition than previous platforms.
