Transfers will be placed here at unmap time instead of incurring
a VM exit. There's an attempt to deduplicate intersecting 1D transfers,
which are surprisingly common.
This can also help with mipmapped texture upload and smaller
textures, where the majority of the time is spent in the guest
kernel / QEMU -- not virglrenderer. This is shown by the GLbench
texture upload benchmark:
Before:
texture_upload_rgba_teximage2d_32 = 64.23 mtexel_sec
After:
texture_upload_rgba_teximage2d_32 = 367.44 mtexel_sec

The idea is to have two command buffers:
1) One for transfers
2) One for commands, which can include transfers
At flush time, (2) will be filled. Otherwise, (1) will be
used to submit transfers if there are enough of them.

Much of our logic is based around the idea the upper 16 bits
of a command dword can encode the length of the command.
Now that the command buffer >= 2^16 - 1, we should check for
this.

Let's define a helper function and use it.
This commit also allows resources to be emitted into different command
buffers.
Like the ioctls, send 0 for layer_stride and stride. If we actually
send the real values, there are various assumptions in virglrenderer
for non-1D buffers that may need to be modified.

Mostly similar to VIRGL_CCMD_RESOURCE_INLINE_WRITE. However, this

There are a few differenes between Mali T860 (Panfrost's primary
reference target) and the older Midgard generations (T600/T700):
- Miscellaneous different magic numbers. It's not clear what these
numbers mean on either the old or new configurations yet.
- Errata fixes. T800 is the final Midgard generation and presumably the
least buggy. Older Midgard has some extra hardware errata we have to
workaround.
- SFBD vs MFBD split. Essentially, older Midgard use a Single
FrameBuffer Descriptor (SFBD), which corresponds to single
render-target rendering. Newer Midgard (T760+) use a Multiple
FrameBuffer Descriptor (MFBD), allowing multiple RTs. On ES 2.0, these
descriptors serve the same function, but we implement both, depending on
the version of the hardware.
- CPU bitness. 32-bit systems generally use 32-bit GPU descriptors, and
vice versa for 64-bit. Our target T760 systems are 32-bit whereas our
target T860 systems are 64-bit. More work is needed in this area.
This patch fixes support in these areas for supporting older Midgard
hardware. It is tested on Mali T760 and Mali T860.

The liveness analysis pass is fairly expensive because it has to build
large bit-sets and run a fix-point algorithm on them. Instead of
requiring liveness for detecting if values escape a CF node, just take
advantage of the structured nature of NIR and use block indices instead.
This only requires the block index metadata which is the fastest we have
metadata to generate.

spirv_to_nir can generate input/output variables which are illegal

dEQP-VK.spirv_assembly.instruction.graphics.module.same_module started
hitting validation errors due to outputs in a TCS (not intended for the
TCS at all) not being per-vertex arrays.
