For non-sparse usage there is no difference between
DRM_XE_VM_BIND_OP_UNMAP_ALL and DRM_XE_VM_BIND_OP_UNMAP but for sparse
the same bo can be bound to more than one virtual address.
Then in a case like:
img = vkCreateImage()
mem = vkAllocateMemory()
vkQueueBindSparse(img, mem)
vkFreeMemory(mem)
Note that the sparse VMA bind still points to the closed bo(done in
vkFreeMemory()), but with DRM_XE_VM_BIND_OP_UNMAP_ALL all VMAs
over the bos are removed.
Access to a unbound VMA has a defined behavior(page fault) while
access to a bound VMA without backing gem/bo don't have defined
behavior.

We need to wait for the batches to complete before we return the BOs
to the pool. We were previously doing this completely synchronously,
which made the code unnecessarily wait. Now we have a timeline syncobj
that signals completion of the previous BOs, so sometimes we check
where we are in the timeline and then return the BOs that we know are
unused.
This, in addition to the previous patch that made us wait for the
other syncobjs through the execbuf ioctl instead of through the CPU,
makes TR-TT batches at least an order of magnitude faster. Still, I

If we're going to move syncobj waiting/signaling down to the backend
we're going to need a queue to signal as lost in case those operations
fail.
In some places of the stack we don't have a queue available, such as
when we're creating or destroying resources. For those, for vm_bind
cases we don't use the queue for anything so passing it as NULL is
fine. For TR-TT we are already using device->trtt.queue.
For TR-TT specifically this also means we're going to start using the
actual queues from the call stack instead of trtt->queue, but that
shouldn't make any difference since we only ever have one queue.

TR-TT is a hardware feature supported by both i915.ko and xe.ko, which
means we can now finally have Sparse Resources on i915.ko and we also
have 2 options for xe.ko (and whatever is the best should be the
default).
In this patch we use batch commands to write the page tables and
forever keep them in device memory. We maintain a mirror of both the
L3 and and L2 tables because that helps us never having to read the
tables that are in device memory.
We still have some things to improve, but with this commit, workloads
that didn't work at all due to the lack of sparse resources should
at least run.
This is still all disabled by default in i915.ko, you can turn it on
