i965/gen9: Add workarounds for object preemption.
Gen9 hardware requires some workarounds to disable preemption depending on the type of primitive being emitted. We implement this by adding a function that checks the primitive type and number of instances right before the 3DPRIMITIVE. For now, we just ignore blorp. The only primitive it emits is 3DPRIM_RECTLIST, and since it's not listed in the workarounds, we can safely leave preemption enabled when it happens. Or it will be disabled by a previous 3DPRIMITIVE, which should be fine too. v3: - Apply missing workarounds for instanced rendering and line loop (Ken) - Move workaround code to brw_draw_single_prim() Signed-off-by: Rafael Antognolli <[email protected]> Cc: Kenneth Graunke <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
