The gmem state is split out now, so it does not require synchronization.
But gmem rendering still accesses vsc state from the context.
TODO maybe there is a better way? For gen's that don't do vsc resizing,
this is probably easier.. but for a6xx there isn't really a great
position for more fine grained locking. Maybe it doesn't matter since
in practice the lock shouldn't be contended.

In a following patch, when we cache the gmem state, we will want to
treat the gmem state as immuatable. So start converting things to
const to make this more clear.. fd_tile is a good place to start.

For the moment, everything is I915_EXEC_RENDER, so this isn't necessary.
But even should that change, I don't think we want to handle multiple
engines in this manner.
Nowadays, we have batch->name (IRIS_BATCH_RENDER, IRIS_BATCH_COMPUTE,
possibly an IRIS_BATCH_BLIT for blorp batches someday), which describes
the functional usage of the batch. We can simply check that and select
an engine for that class of work (assuming there ever is more than one).

For all VMEM instructions, the resource constant is now
in operands[0]. For MIMG instructions, the sampler shares
operands[1] with write data in case this instruction writes memory.
Moving the VADDR to be the last operand for MIMG is the first step to
support Navi NSA encoding.

In a NIR generated using SPIR-V initializers to variables, copy
propagation can end up transforming
vec1 32 ssa_33 = deref_var &@1 (shared mat2x4)
vec1 32 ssa_35 = mov ssa_33
vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_35 (shared mat2x4) /* ptr_stride=0 */
into
vec1 32 ssa_33 = deref_var &@1 (shared mat2x4)
vec1 32 ssa_7 = deref_cast (mat2x4 *)ssa_33 (shared mat2x4) /* ptr_stride=0 */
Before the optimization, the "head" of a path of deref that uses ssa_7
will be the cast. After, it will be the variable in ssa_33. Since
the types are the same, this is a trivial cast that would be picked up
by nir_opt_deref.
If we need to compare such deref-chain after optimization with another
deref-chain for the same variable, the compare function will get
confused by the cast in the middle.
One alternative would be to add nir_opt_deref to places that compare
derefs, but that might not scale well, so skip the trivial casts when
generating the paths instead.

The continue_or_break block doesn't have any logical predecessors but it's

A shader might require vgpr spilling but not require sgpr spilling. In
that case, the spiller lowers the sgpr target by 5 which could mean sgpr
spilling is then required. Then the vgpr target has to be lowered to make
space for the linear vgprs. Previously, space wasn't make for the linear
vgprs.

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.
