On pre-Xe2 platforms, the compression on these modifiers that
don't support compression are enabled. The compressed will be
resolved when needed. On Xe2+ we haven't support explicit
resolve, so all the paths to resolves are prohibited now. But
the code is still doing it, causing an assertion failure:

From all the many possible errors returned by the vm_bind ioctl, some
can actually happen in the wild when the system is under memory
pressure. Thomas Hellström pointed to us that, due to its asynchronous
nature, the vm_bind ioctl itself has to pin some memory, so if the
number of bind operations passed is too big, there is a probability
that it may run out of memory.
Previously the Kernel would return ENOMEM when this condition
happened. Since commit e8babb280b5e ("drm/xe: Convert multiple bind
ops into single job") the Kernel has started returning ENOBUFS when it
doesn't have enough memory to do what it wants but thinks we'd succeed
if we tried to do one bind operation at a time (instead of doing
multiple operations in the same ioctl), and ENOMEM in some other
situations. Still-uncommitted commit "drm/xe: Return -ENOBUFS if a
kmalloc fails which is tied to an array of binds" proposes converting
a few more ENOMEM cases no ENOBUFS.
Still, even ENOMEM situations could in theory be possible to recover
from, because if we wait some amount of time, resources that may have
been consuming memory could end up being freed by other threads or
processes, allowing the operations to succeed. So our main idea in
this patch is that we treat both ENOMEM and ENOBUFS in the same way,
so our implementation can work with any xe.ko driver regardless of
having or not having the commits mentioned above.
So in this patch, when we detect the system is under memory pressure
(i.e., the vm_bind() function returns VK_ERROR_OUT_OF_HOST_MEMORY), we
throw away our performance expectations and try to go slowly and
steady. First we wait everything we're supposed to wait (hoping that
this alone could also help to alleviate the memory pressure), and then
we synchronously bind one piece at a time (as this will ensure ENOBUFS
can't be returned), hoping that this won't cause the Kernel to try to
reserve too much memory. All this while also hoping that whatever
thing that may be eating all the memory goes away in the meantime. If
even this fails, we give up and hope the upper layer will be able to
figure out what to do.
This fixes a bunch of LNL failures and flaky tests (as LNL is our
first officially supported xe.ko platform). This can be seen in dEQP
but only if multiple tests are being run parallel. Happens in multiple
tests, some of which may include:
- dEQP-VK.sparse_resources.image_sparse_binding.2d_array.rgba8_snorm.1024_128_8
- dEQP-VK.sparse_resources.image_sparse_binding.3d.rgba16_snorm.1024_128_8
- dEQP-VK.sparse_resources.image_sparse_binding.3d.rgba16ui.512_256_6
I don't ever see these errors when running Alchemist/DG2 with xe.ko.

We want to use actual sparse-capable queues as the default
trtt->queue, not copy queues that may have a companion_rcs_batch.
Before this patch, if we expose more than one queue *and* the
application creates a copy queue first, we'll end up setting
trtt->queue as the copy queue, which will GPU hang when we submit the
TR-TT batches as they don't support the pipe_control commands we
issue.
The trtt->queue queue is used for binding/unbinding buffers in code
paths where there's no specific queue coming from user space, such as
when we're creating or destroying a sparse resource.
This is not a problem yet on i915.ko since we are exposing
only a single queue, and it is not a problem for xe.ko since TR-TT is
not the default there. This is also not a problem in applications
that create the render or compute queue first. We plan to expose more
queues when using TR-TT, so this would become a problem without this
patch.
None of VK-GL-CTS seems to exercise that, and none of the Steam games
I tested exercise that as well. I was able to reproduce this issue
using our internal tracing tool.

queue (Lionel).

On Gen12 (the oldest we support on Mesa right now for TR-TT) we
started having per-engine TR-TT registers and we are supposed to make
all contexts share the same TR-TT programming.
On LNL+, this is documented in the BSpec page for the TRTT_CNTRL
register (68417), with more details in HSDs 14020454786 and
16022013154.
On Gen12 platforms this information is a little harder to find and
there's a whole trail of HSDs leading up to 1209977595, which links to
the documents that describe the programming. BSpec for TR-TT on Gen12
is very confusing as it still contains registers and other information
from Gen11 that were not removed.
Regarding the additional BLT and COMP registers, please notice that on
the BSpec pages for the TR-TT registers, the "Register Instance"
section only lists the GFX registers as non-privileged. However, the
"User Mode Privileged Commands" lists the other instances of the TR-TT
Regsiters as non-privileged, which matches what we see: there's no
need to put these addresses in the FORCE_TO_NONPRIV registers.
Notice that for now, when TR-TT is being used we only expose a single
queue, so this change effectively does nothing until we start exposing
extra queues. I left that part for later to help bisectability.

While it certainly sounds better to do everything related to TR-TT

because we'll want to run this batch on every engine.

Pretty big change... Sorry for that.
I can't exactly remember why I created 2 heaps. I think it's because I
mistakenly thought the samplers in the binding sampler pointers needed
to be indexed from the binding table. But that's not the case, they
just need to be in the dynamic state heap.
In the future, this change will allow to also allocate buffers for
push constant data in the newly created dynamic_visible_pool which
will be useful on < Gfx12.0 where this is the only place push constant
data can live for compute shaders.

cache, which is quite expensive.
