This is the first time we see an application running out of mmap().
We essentially allocate too many batches (+65k) and end up not being
able to mmap them, at which point we can't mmap anything anymore and
things go sideways.
This change allocates bigger batch BOs as we grow an existing command
buffer. This drastically reduces the number of BOs we need to allocate
(the benchmark that reported the issue now reaches a max of ~630 BOs,
instead of reaching 65k and failing previously).

According to the BSpec page for MEDIA_VFE_STATE, on Gen12 platforms
"if a fused configuration has fewer threads than the native POR
configuration, the scratch space allocation is based on the number of
threads in the base native POR configuration". However we currently
use the subslice count from devinfo->num_subslices[0], which only
includes the subslices currently enabled by the platform fusing. This
leads to scratch space underallocation and occasional hangs.
The problem is likely to affect most Gen12 GPUs with less than 96 EUs.
GFXBench5 Aztec Ruins is able to reproduce the issue fairly reliably.

In d11e4738a8, we started using a start_offset to allow us to
allocate pools where the base address isn't at the start of the pool.
This is useful for binding table pools which want to be relative to
surface state base address (more or less), among other things. However,
we had a bug where, if you have a negative offset, everything returned
to the pool would end up being returned to the "back" of the pool. This
isn't what we want for binding tables in the softpin world. This was
causing us to never actually re-use any binding table blocks. How this
passed CTS, I have no idea.

This allows a pool's allocations to start somewhere other than the base

When we originally wrote a bunch of the allocation data structures, we
re-used the GPU memory for CPU-side data structures. It's a bit more
memory efficient and usually ok. However, this has a couple of
problems:
1. It makes it MUCH more likely that the GPU will accidentlly stomp
CPU-side data structures and cause nearly impossible to debug
crashes.
2. With discrete GPUs, the memory will be mapped somehow and that map
may be across the BAR so it could have horribly slow CPU access.
This is bad for our CPU-side data structures.
In the case of anv_state_stream, it also made the data structure
massively more complex than it needed to be.

The number of EUs on TGL is not the same as ICL, but the

Also, consider the base configuration instead of what we read from the

Because softpin block pools are made up of a set of BOs with different
maps, it was possible for a single state to end up straddling blocks.
To fix this, we pass a contiguous size to anv_block_pool_grow and it
ensures that the next allocation in the pool will have at least that
size.
We also add an assert in anv_block_pool_map to ensure we always get
contiguous maps. Prior to the changes to anv_block_pool_grow, the unit
tests failed with this assert. With this patch, the tests pass.
This was causing problems on Gen12 where we allocate the pages for the
AUX table from the dynamic state pool. The first chunk, which gets
allocated very early in the pool's history, is 1MB which was enough that
it was getting multiple BOs. This caused the gen_aux_map code to write
outside of the map and overwrite the instruction state pool buffer which
lead to GPU hangs.

The previous way we were attempting to handle AUX tables on TGL-LP was
very GL-like. We used the same aux table management code that's shared
with iris and we updated the table on image create/destroy. The problem
with this is that Vulkan allows multiple VkImage objects to be bound to
the same memory location simultaneously and the app can ping-pong back
and forth between them in the same command buffer. Because the AUX
table contains format-specific data, we cannot support this ping-pong
behavior with only CPU updates of the AUX table.
The new mechanism switches things around a bit and instead makes the aux
data part of the BO. At BO creation time, a bit of space is appended to
the end of the BO for AUX data and the AUX table is updated in bulk for
the entire BO. The problem here, of course, is that we can't insert the
format-specific data into the AUX table at BO create time.
Fortunately, Vulkan has a requirement that every TILING_OPTIMAL image
must be initialized prior to use by transitioning the image from
VK_IMAGE_LAYOUT_UNDEFINED to something else. When doing the above
described ping-pong behavior, the app has to do such an initialization
transition every time it corrupts the underlying memory of the VkImage
by using it as something else. We can hook into this initialization and
use it to update the AUX-TT entries from the command streamer. This way
the AUX table gets its format information, apps get aliasing support,
and everyone is happy.
One side-effect of this is that we disallow CCS on shared buffers.
We'll need to fix this for modifiers on the scanout path but that's a
task for another patch. We should be able to do it with dedicated
allocations.
