"most" times it isn't necessary to insert any pipeline barriers when binding
descriptors, as GL requires explicit barrier usage which comes through a different
codepath
the exception here is when the following scenario occurs:
* have buffer A
* buffer_subdata is called on A
* discard path is taken || A is not host-visible
* stream uploader is used for host write
* CmdCopyBuffer is used to copy the data back to A
buffer A now has a pending TRANSFER write that must complete before the buffer is
used in a shader, so synchronization is required any time TRANSFER usage is detected
in a bind
there's also going to be more exceptions going forward as more internal usage is added,
so just remove the whole fake-barrier mechanism since it'll become more problematic
going forward

The idea is to offer the driver a way to execute on a different queue
than the one the app is using for Present.
For instance, this could be used to make the DRI_PRIME blit asynchronous,
by using a transfer queue.
So instead of creating a command buffer to be executed on present using
the supplied queue, this commit uses an internal transfer queue to perform
the blit.

The coarser 32x32 cross-slice hashing mode seems to lead to better L1
and L2 utilization due to the improved execution locality, however it
can also lead to a bottleneck in a single slice, especially in
workloads that concentrate heavy rendering in small areas of the
screen (e.g. SynMark2 OglGeomPoint, OglTerrain*) -- This effect is
mitigated here by performing a permutation of the pixel pipe hashing
tables that ensures that adjacent rows map to pixel pipes as far away
as possible in the caching hierarchy.

It's now an array with 7 tables, each table is intended to specify the
pixel pipe hashing behavior for every possible slice count between 2
and 8, however that doesn't actually work, among other reasons due to
hardware bugs that will cause the GPU to erroneously access the table
at the wrong index in some cases, so in practice all 7 tables need to
be initialized to the same value.

The current packed dispatch assumptions for fragment shaders seem to
be the reason that the fs-readFirstInvocation-uint-loop Piglit
test-case for the ARB_shader_ballot extension fails on DG2 in
combination with the patches in this series that enable pixel pipe
hashing (thanks Jordan for reporting the regression). I've confirmed
that the brw_fs_test_dispatch_packing() test fails on DG2 hardware for
fragment shaders, while it succeeds for other shader stages,
indicating that the PSD hardware no longer guarantees packed dispatch.

Actually, no, there's no need to do anything, just update some
comments for the record. An earlier revision of this change that
implemented the workaround text to the letter required no less than 8
new PIPE_CONTROLs throughout the tree. However Felix Degrood noticed
that the cost of some of the PIPE_CONTROLs was showing up in workloads
like Shadow of the Tomb Raider. The Windows driver wasn't emitting
many of those pipe controls, contrary to the W/A instructions, so we
engaged in a back and forth with the hardware team, who concluded that
the original suggested workaround was unnecessarily strict, and the
Windows driver's behavior acceptable. It turns out that Wa_1408224581
we had already implemented for TGL is roughly equivalent to the
Windows behavior, so no need to do anything new after all.
