One concern is that iris uses larger batches, and also emits far fewer

could need to supplement this with actual counting.  Manhattan 3.0 had

panfrost: Do fine-grained flushing when preparing BO for CPU accesses

We don't have to flush all batches when we're only interested in
reading/writing a specific BO. Thanks to the
panfrost_flush_batches_accessing_bo() and panfrost_bo_wait() helpers
we can now flush only the batches touching the BO we want to access
from the CPU.

panfrost: Extend the panfrost_batch_add_bo() API to pass access flags

The type of access being done on a BO has impacts on job scheduling
(shared resources being written enforce serialization while those
being read only allow for job parallelization) and BO lifetime (the
fragment job might last longer than the vertex/tiler ones, if we can,
it's good to release BOs earlier so that others can re-use them
through the BO re-use cache).

Let's pass extra access flags to panfrost_batch_add_bo() and
panfrost_batch_create_bo() so the batch submission logic can take the
appropriate when submitting batches. Note that this information is not
used yet, we're just patching callers to pass the correct flags here.

anv/block_pool: Align anv_block_pool state to 64 bits.

On 64 bits platforms, some atomic operations like __sync_fetch_and_add()
have constant time, but on 32 bits platforms they are implemented with a
loop and might take much longer.

Additionally, it seems like if their operands are not aligned to 64
bits, they also require extra memory accesses. From the Intel
Architecture's Developer Manual Vol. 1, 4.1.1:

 "A word or doubleword operand that crosses a 4-byte boundary or a
 quadword operand that crosses an 8-byte boundary is considered
 unaligned and requires two separate memory bus cycles for access."

Forcing the u64 field to be aligned to 64 bits seems to make the unit
tests that are stressing this finish much faster.
