Opaque fds are internally dma-bufs. We also support both export and
import. But for dma-bufs, we additonally require the image tiling
allows vkGetImageSubresourceLayout for export and
VkImageDrmFormatModifierExplicitCreateInfoEXT for import.

Texel buffer could be arbitrary large, so the assumption being made in
the following comment is wrong:
"Zero-extension (u16) and sign-extension (i16) have
the same behavior here - txf returns 0 if bit 15 is set
because it's out of bounds and the higher bits don't matter."
Sign extension should matter for GLSL_SAMPLER_DIM_BUF.
This fixes the case of doing texelFetch with u16 offset:
uniform itextureBuffer s1;
uint16_t offset = some_ssbo.offset;
value = texelFetch(s1, offset).x;
If the offset is higher than s16 optimization incorrectly
left it as 16b.
In spirv the above glsl is translated into:
%22 = OpLoad %ushort %21
%23 = OpUConvert %uint %22
%24 = OpBitcast %int %23
%26 = OpImageFetch %v4int %16 %24

Since the L2 bug fix we've been overestimating l3l2_binds by a lot in
most of the cases: almost every single call to anv_sparse_bind_trtt
ends up using either 0 or 1 elements for l3l2_binds, with occasionally
something using 512 or more. By switching to util_dynarray we can
guarantee the best of every case:
- l1_binds will remain a stack array for the vast majority of the
calls
- even more than before, since STACK_ARRAY was limited to 8
elements and now we do 32
- l1 will be properly dimensioned without the need for reallocs
- l3l2_binds will be completely empty most of the times and only
trigger allocations when necessary
Here's the top 10 most common results of anv_sparse_bind_trtt() for a
trace of Assassin's Creed: Valhalla. The first column is how many
times we had that case while running the trace. After this patch, all
these cases will proceed without any memory allocations.
168 trtt_binds: num_vm_binds:04 l3l2:0000 l1:0004
344 trtt_binds: num_vm_binds:01 l3l2:0000 l1:0004
420 trtt_binds: num_vm_binds:01 l3l2:0000 l1:0012
422 trtt_binds: num_vm_binds:04 l3l2:0000 l1:0008

3735 trtt_binds: num_vm_binds:01 l3l2:0000 l1:0001
Only 70 out of total 11340 calls to anv_sparse_bind_trtt() contained
l3l2 elements.

We use 2MB page table BOs, as defined by ANV_TRTT_PAGE_TABLE_BO_SIZE.
Each BO is enough to hold 512 pages, since each one has 4096 bytes.
Each L1 page can fit 1024 entries of 64kb size, which means our 512
pages should be able to fit a little less than 32gb of sparse resource
memory, since we also need some L2 pages and an L3 page. I don't see
any real world application using more than a single BO.

The application can submit bind operations where it simply resets
state that is already in our page tables, so there's nothing to do.
Before commit 7da5b1caef ("anv: move trtt submissions over to the
anv_async_submit") we would simply return and not submit any batches
when this happened, but the commit reorganized things in a way where
we started submitting empty batches instead.
Fix this by simply jumping out when we detect this case. Because of
this, rename the "error" labels to "out" as they can now happen on a
happy case.
It should be noted that an alternative to this implementation would be
to move all the handling of 'submit' to after the n_lX_binds check,
but this would put all the initialization inside the trtt->mutex,
creating extra contention even when we have stuff to bind. Since the
"there's nothing to bind" check is now rare (after we stopped doing
NULL binds during resource creation), it is probably better to reduce
lock contention in the common case at the expense of a little more CPU
in the rare case.

There is a lot that can go wrong during initialization after we assign
trtt->l3_addr, and we use its value to check if trtt is initialized.
If an initialization fails after l3_addr is already assigned, the next
bind will attempt to use the leftover values from the failed
initialization attempt and will likely cause all sorts of random
errors. So when we fail, just set l3_addr back to 0, causing the next
bind to attempt to initialize everything again.

Since everything is always NULL-bound at init and we always bind
things back to NULL in anv_free_sparse_bindings(), this means we don't
need to do NULL bindings during anv_init_sparse_bindings(), saving us
a bunch of time, espcially since we don't track L1 entries so we may
end up submitting TR-TT batches just to write zeroes on top of zeroes.

When we create sparse resources the first thing we do is a NULL bind
on them, as the Vulkan spec mandates certain behavior even for unbound
sparse resources. We do this with the minimal effort possible: if we
can get away with marking an L2 pointer as NULL in the L3 table, we
just do it and return, instead of going all the way to creating L1
tables and marking all the final entries as NULL.
The strategy we were using had a bug that could lead to previously
created NULL entries not being marked as NULL anymore. Let's give an
example:
(before proceeding, keep in mind that a NULL entry in the L3 and L2
tables has bit 1 set, it does *not* have the value 0)
- Create a 64mb buffer that uses an entire L1 table (needs to be
properly aligned), which triggers a NULL bind.
- Our algorithm will just set the L3 entry (pointing to the L2
table) as NULL.
- Create a 64kb buffer that uses the same L2 table (but a different
L1 table).
- The NULL bind triggered won't do anything as the L2 table is
already NULL.
- Bind the first buffer to actual memory. This will end up creating
the L2 table and the L1 table. The only entry we will set in the L2
table will be the one pointing to the L1 table. All the other
values will be 0 (so they won't have neither the NULL or Invalid
bits set: access to them will lead to page faults).
- Try to use the second buffer, which is still unbound. It was
relying on the fact that its L2 table pointer was NULL, but now
it's not anymore, so the page walker will fetch the L1 entries in
the L2 table and they will all be zero instead of having the NULL
bit set.
The fix is pretty simple: whenever we create a new L2 table, set every
entry to NULL (except the one we're about to set to non-NULL). This
preserves behavior for every other NULL resource relying on the L3
entry being set to NULL.
We don't need to do this for the L1 table because its entries are
different and instead of having bits to signal NULL entries we have
a special TR-TT register that we can set that gets compared to check
if an entry is NULL, and we conveniently program it to 0: see
ANV_TRTT_L1_NULL_TILE_VAL.
I am not aware of any real workloads that are triggering this
behavior, I found this issue while investigating something else,
running a custom sparse program in our pre-silicon environment, and it
told us about the page faults.
