After a great deal of spec lawyering in #dri-devel, I am convinced this
is probably okay for the same reasons as v3d and freedreno. The batch
reordering and flush deferral optimizations are seemingly still ok. The
requirement that writes are visible "immediately" in the spec actually
means "in the subsequent [OpenGL] command" for the CPU -> GPU direction,
which avoids pitfalls where PERSISTENT|COHERENT could be used as a
"doorbell". With that understanding, the extension doesn't actually
require anything special for tilers other than coherency at GPU submit
boundaries, which is true for any driver that does not use a sync ioctl.
After this commit, the remaining drivers that don't set the CAP are
d3d12, softpipe, etnaviv, and i915g. I am unsure about d3d12, but the
latter 3 could probbaly enable it trivially for the same reason.
v2: Don't use copy_resource path for persistent mappings (Emma). Emma
explained on GitLab:
I don't think you should have the copy_resource path taken for
PIPE_RESOURCE_FLAG_MAP_PERSISTENT BOs. Imagine the user has a
general-purpose BO they're streaming stuff into and doing draws that
they keep persistently mapped until wrapping. They call some GL
function on the same buffer that does a fallback write map on the BO
(u_default_buffer_subdata, util_resource_copy_region, whatever) -- the
buffer is in use, copy triggers, allocates a new BO. Whoops, the user's
pointer for streaming writes is now freed.
Closes: #7570

Some drivers have minimum buffer size or alignment requirements. When a
buffer is created using pb_cache_manager_create_buffer, the cache is
first checked for a compatible buffer to return instead. If the
requested buffer size is less than
(minimum buffer size) / (mgr->size_factor), no buffer in the cache
is _ever_ applicable.
The alignment is used to determine the true allocation size when
evaluating against cached buffers.

We can just bake this into the program state, rather than making it a

For MSAA downsampling to work correctly, the BLT engine needs to know
the exact format of the blit source/target. The compatible formats are
fine as long as the BLT is only used as a tiler without doing any
