I never finished the irq ack+handler split for ilk+. Let's try to do
that now since people seem keen on cleaning up stuff in there. One
thing I didn't dare touch is gen11_gt_irq_handler() as that thing
looks a bit nuts.
A bit of a downside:
Total: Before=39303, After=40393, chg +2.77%
If we changed all _ack()s to raw_reg_{read,write} we'd get:
Total: Before=39303, After=39258, chg -0.11%
but that ignores the "hang when accessing registers in the
same cacheline" fail. So would need a bit more thought.
Ville Syrjälä (4):
drm/i915: Add gen8_de_pipe_fault_mask()
drm/i915: Introduce struct hpd_irq_regs
drm/i915: Split pch irq handling to ack+handler
drm/i915: Finish the irq ack+handler split for ilk+
