"16TB ought to be enough for anybody."
- Probably some Intel graphics hardware engineer
TR-TT addresses are fixed regardless of the platform's gtt_size.
Unconditionally reserve this space for it: our total 48bit address
space is 256tb and TR-TT takes 16tb out of it (1/16th).

This function will be able to transparently handle sparse binding
regardless of the backend: vm_bind ioctls or TR-TT. For now we only
support the vm_bind ioctls, but soon we'll have anv_sparse_bind_trtt()
as an option.
It is important to notice that even backends that support the vm_bind
ioctl may choose to do Sparse binding via TR-TT, that's why we're
adding the indirection at this specific point.

If the next bind is just an extension of the previous one, join both
in the same bind operation. Due to how mip levels are laid in memory,
this can only happen for mip level 0.
As of today xe.ko doesn't try to join contiguous operations for us.
Due to how rebinds happen each additional rebind operation may end up
resulting in many extra things done, so these simple checks end up
saving us a lot of cycles the Kernel would otherwise waste. This will
be true even after we issue all binds in a single ioctl.

Kill vma_cva and just toggle heap->alloc_high instead. This way,
client visible addresses will remain isolated in their own little
corner, except we have one less vma to deal with.
For TR-TT we'll need a special vma, and if we don't use the trick
above we'll need yet another trtt_cva_vma, increasing complexity even
more.

This actually doesn't fix any bugs or leaks, because according to the
man page:
"In the LinuxThreads implementation, no resources are associated
with mutex objects, thus pthread_mutex_destroy actually does
nothing except checking that the mutex is unlocked.
still, it's better to have it than not to have it, especially since
other implementations may do something.

* Add support for PIPE_BUFFER in resource_from_handle.
* Flush batches after reallocate_resource_inplace:
If we're dealing with a PIPE_BUFFER, iris_flush_resource doesn't
flush the batch and we export the resource with pending commands.

For a dGPU, we should have:
1. RAM
2. RAM + write-combined CPU access
3. RAM + cached CPU access
4. VRAM
Eventually there'll be VRAM + write-combined CPU access after 4, using "GPU upload heaps"
For an iGPU, we should have:
1. RAM (declared as device-local)
2. RAM + write-combined CPU access (declared as device-local)
3. RAM + cached CPU access (declared as device-local)

Vulkan video has parameter overrides, where the driver can override the
driver provided parameters with an encoded bitstream where it has made
changes.
This is the support code to encode the bitstream headers for h265
from parameters (vps/sps/pps).

We've supported storageImageReadWithoutFormat for a while. Also, thanks
to the fact that the assert assumed image_deref_load and happened after
nir_rewrite_image_intrinsic, it would never trigger.

a630 has been completing jobs, and then corrupting the very last line of
UART output - the one where we pass the overall result back from the DUT
to the job. The bare-metal monitor will wait for this line to appear,
never see it, and then the job times out.
Since this line is the most critical one of all to get out, just spam
the prints to try to make sure they get through.
