Add graphics IP versions 35.10. Since there will be features enabled
that are not present in graphics_xe2, already create a new
graphics_xe3p, although currently it only enables the same features as
graphics_xe2.
Here is a list of fields, associated Bspec references and eventual
comments:
.va_bits (Bspec 74198)
.vm_max_level (Bspec 59507)
The spec says "The PPGTT is always a 5-level structure even when the
virtual address space is less than 57 bits."
.vram_flags
- ~XE_VRAM_FLAGS_NEED64K
That limitation that does not exist for Xe3p_LPG.
.hw_engine_mask (Bspec 60149)
.tile_gsm_size (Bspec 52961)
This is queried directly from the hardware.
.has_asid (Bspec 71132)
.has_atomic_enable_pte_bit (Bspec 59510, 74675)
.has_flat_ccs (Bspec 65255)
.has_indirect_ring_state (Bspec 67296)
.has_range_tlb_inval (Bspec 71126)
.has_usm (Bspec 59651)
