We currently disable CCS if a 3D Ys/Yf surface uses miptails. However,
ISL generally configures surfaces to be compatible with compression. For
consistency, disable miptails on 3D Ys/Yf surfaces in order to allow
compression.
If drivers prefer to have a more compact layout, they can pass the
ISL_SURF_USAGE_DISABLE_AUX_BIT flag at surface creation time.

Some games such as Marvel's Spider-Man Remastered and Assassin's
Creed: Valhalla don't work in debug mode because they hit this
assertion. In Release mode, they appear to work (although in some
platforms there may be visual corruption or GPU hangs). There's
nothing we can do about this error (see below), so in this patch we
replace the assertion with an error message, because it allows us to
(i) test the rest of the game in debug mode so we may catch other
issues; and (ii) warn users of release mode that the issue is
happening.
The unsupported num_elements comes from vkGetDescriptorEXT() and
appears to be violating VUID-VkDescriptorGetInfoEXT-type-09427. This
function cannot return errors, but we can disable
VK_EXT_descriptor_buffer.
If we do disable the extension, then vkCreateBufferView() will start
triggering the assertion, and we can see that
VkBufferViewCreateInfo-range-00930 is being violated. If we change Anv
to return errors on these vkCreateBufferView() cases, then the games
won't work at all.
I reported this to vkd3d-proton, but according to the vkd3d-proton
developer Philip Rebohle:
"There's also the problematic case of games using typed descriptors
but passing non-typed buffer descriptors, which is an extremely
common app bug that works on all D3D12 drivers that we need to work
around by creating typed views. If that's what's happening here then
the best we can do is to just not create the typed view and have the
game be broken entirely, or create a smaller view and most likely
still completely break the game, but at least that way it wouldn't
trigger Vulkan validation. Emulating larger views via multiple
smaller views is not possible for us."
"Confirmed that it's the app itself creating these views."
"D3D12 does not have runtime validation for this or any sort of query
for the app, so we really can't do much here."

In the import paths in iris, there are several cases where surface VMAs
are created without relying on the calculated surface alignment.
Asserting the alignments of surface addresses, should help catch any
cases where we end up with the wrong alignment.
This found a couple issues during development. One which required a
change to existing code is that when creating uncompressed surfaces from
compressed ones, ISL will sometimes increase the image alignment as a
result of the new format supporting CCS. This patch adds the usage flag
to disable that behavior.

Add and use two new surf usage bits:

* ISL_SURF_USAGE_MULTI_ENGINE_PAR_BIT: the surface may be accessed by
multiple engines in parallel.
Both usages are not concerned with read-after-read access patterns.
Using these bits allows ISL to conditionally use Tile64 or a 64KB
alignment to account for the gfx12.5 CCS WA from HSD 22015614752. Apart
from the potential space savings, there are three benefits of this
approach:
1) CCS can now be used with miptails (though nothing makes use of this
today).
2) CCS can now be used with 3D depth/stencil surfaces in GL.
3) CCS can now be used with 3D depth/stencil surfaces in Vulkan when
apps only use a single queue.

In iris, use the CCS scale down factor to calculate the impact of CCS on
TBIMR tile sizes. Even though we fall back to a seemingly less accurate
method to calculate the impact of CCS, it ends up giving the same
answer, 1bpp. Anv already uses this factor, so this patch replaces the
constant with this macro.
There are two benefits to doing this:
1) Consistency between anv and iris.
2) Preparation for a future where we no longer use ISL surfaces to
describe CCS on Xe+. In fact, in iris, we already don't create such
surfaces on ACM.
I considered using INTEL_AUX_MAP_MAIN_SIZE_SCALEDOWN for the calculation
in both drivers, but the naming is aux-map specific and the scaledown
actually exists on flat-ccs platforms as well.
So, we introduce a new macro for all Xe platforms, currently only used
for the specific use case of TBIMR calculations. We can add more such
macros for future platforms, as needed.
