This path supports layers but it requires to decompress HTILE
before resolving. The driver also needs to fixup HTILE after
the resolve. This path is probably slower than the graphics one.

Most vertex data lives in user VBOs in IRIS_MEMZONE_OTHER, which
typically have high bits set to 0xffff. The shader draw parameters were
being uploaded in IRIS_MEMZONE_DYNAMIC, which have high bets set to 0x2.
This was causing a lot of ping-ponging of high bits, leading to
unnecessary VF cache flushing.
Cuts 7.2% of the flushes in the Civizilation VI demo on Kabylake GT2.
If there is no buffer, then it doesn't matter. Leave the old stale
high bits in place (for next time) and don't bother invalidating.
Cuts 5.6% of the flushes in the Civilization VI demo on Kabylake GT2.
If a buffer has no usage history, we don't have any read only cache
invalidates to do. If we've written it with the CPU, we don't need
to flush the render cache. The only bit remaining is the CS stall
from iris_flush_bits_for_history. We can just skip the PIPE_CONTROL
in this case.
This is pretty common - an app creates a buffer, fills it with data,
and then binds it for some purpose.
Cuts 36% of the flushes in Manhattan 3.0 on Kabylake GT2.
Instead of using the combined iris_flush_and_dirty_for_history, use
iris_flush_bits_for_history directly - we were already using the split
out iris_dirty_for_history. There's no need to dirty twice, and we can
avoid the looping altogether for non-buffers.
My intention was to have iris_copy_region not do flushing, and leave
that up to the callers. iris_resource_copy_region needs to do this,
but iris_transfer_flush_region was already doing it. The net result
was that we were doing it twice for transfers.
So, move the flushing from iris_copy_region to iris_resource_copy_region
so that it only happens in the callers as I intended.
When I split iris_flush_and_dirty_history into two helper functions,
I accidentally made it stop dirtying. Which was...sort of the point.
Fixes: 21688a306b iris: Split iris_flush_and_dirty_for_history into two helpers.
Otherwise, tests which loop on glMemoryBarrier may run us out of
batch space with piles of flushing. (Ideally, we'd elide those bonus
PIPE_CONTROLs, but presumably this isn't that common of a case...)
Piglit's arb_pipeline_statistics_query-comp would hit this case after
some of the next patches remove other PIPE_CONTROLs with maybe_flushes.
This prints a log of every PIPE_CONTROL flush we emit, noting which bits
were set, and also the reason for the flush. That way we can see which
are caused by hardware workarounds, render-to-texture, buffer updates,
and so on. It should make it easier to determine whether we're doing
too many flushes and why.
Looking at the scissor, we can discard some tiles. We specifially don't
care about the scissor on the wallpaper, since that's a no-op if the
entire tile is culled.
