We lower NIR's load_constant to load_global_constant, which uses A64
bindless messages. As such, we do the following math to produce the
address for each load:
base_lo@32 <- BRW_SHADER_RELOC_CONST_DATA_ADDR_LOW
base_hi@32 <- BRW_SHADER_RELOC_CONST_DATA_ADDR_HIGH
base@64 <- pack_64_2x32_split(base_lo, base_hi)
addr@64 <- iadd(base@64, u2u64(offset@32))
On platforms that emulate 64-bit math, we have to emit additional code
for the 64-bit iadd to handle the possibility of a carry happening and
affecting the top bits.
However, NIR constant data is always uploaded adjacent to the shader
assembly, in the same buffer. These buffers are required to live in a
4GB region of memory starting at Instruction State Base Address. We
always place the base address at a 4GB address. So the constant data
always lives in a buffer entirely contained within a 4GB region, which
means any offsets from the start of the buffer cannot possibly affect
the high bits.
So instead, we can simply do a 32-bit addition between the low bits of
the base and the offset, then pack that with the unchanged high bits.
On anv, INSTRUCTION_STATE_POOL_MIN_ADDRESS is 8GB, so the high bits are
always 0x2. We don't even need to patch that portion of the address and
can just use an immediate value. We do still need to pack, however.

where the top bits are 0.

They got accidentally disabled entirely, so they didn't block merge, but
once they re-enable then they'll block us again. The problem was that I
moved allow_failure to a .performance-rules section, but we only ever
inherit the rules from that location, not the rest of yml.
This is basically a revert of 67547a04b6 ("ci: Move the performance
jobs' allow_failure:true to the gl rules."), though I still keep the
allow_failure in a more common location with comments, since perf jobs are
a huge trap.

u_vector_add() don't keep the returned pointers valid.
After the initial size allocated in u_vector_init() is reached it will
allocate a bigger buffer and copy data from older buffer to the new
one and free the old buffer, making all the previous pointers returned
by u_vector_add() invalid and crashing the application when trying to
access it.
This is reproduced when running
dEQP-VK.synchronization.signal_order.timeline_semaphore.* in DG2 SKUs
that has 4 CCS engines, INTEL_COMPUTE_CLASS=1 is set and of course
perfetto build is enabled.
To fix this issue here I'm moving the storage/allocation of
struct intel_ds_queue to struct anv_queue/iris_batch and using
struct list_head to maintain a chain of intel_ds_queue of the
intel_ds_device.
This allows us to append or remove queues dynamically in future if
necessary.
