Uncached access can be slow if the box is not aligned nicely.
Also, caching in L2 might enable bigger PCIe bursts.

If a shader has no param exports (no varyings), the pixel shader can start
after the VS position is written before the vertex shader finishes.
The fix is to wait for the memory stores before the position export.
The code needs to be restructured. First prepare param exports to get
nr_param_exports, then emit position exports with the wait, and then
emit param exports.

This way if there's a fault, the pipeline won't accidentally pass
and let bugs slip into main. This seems to have occurred on both T720
and G72, leading to flakes on both. I want flakeless CI, so this is a
step in eliminating flakes before they hit the tree.

It's reliably faulting in CI but not locally, and I can't figure out
what the difference could possibly be. Regardless I can't fix the fault
otherwise, and faultless CI matters more than losing a single trace
(from an app I manually test anyway).

We previously allocated only 16MB, but this isn't always enough. Now
that we have growable (heap) on recent kernels, there's not much reason
to try to shrink this allocation.

This allows failing fast (optionally still tracing, if set with
PAN_MESA_DEBUG=trace) when a GPU fault is introduced. This is better
behaviour for both use cases:
1. When debugging a known fault, setting this mode together with trace
will stop the driver as soon as a buggy command stream is submitted,
and the offending stream will be the last trace file.
2. When running test suites (particularly in CI), setting this mode
will detect faults and crash, causing the pipeline to fail fast as
opposed to incorrectly marking the run green if the test happens to
pass despite the faults and slow downs.

Due to Midgard ABI silliness. We could fix this properly but I'm not
aware of any app that needs more than 16, so let's just revert to the
behaviour matching the DDK.

Some resources like backbuffers are explicitly flushed by the frontend
at the appropriate time, others however won't get flushed explicitly.
Remember those resources when they get emitted as a render buffer and
flush them on a context flush to make their content visible to other
entities sharing the buffer.
We still keep the optimized path for most resources where the frontend
promises to do the flushing for us and only enable implicit flushing
when a buffer handle is exported/imported without the
PIPE_HANDLE_USAGE_EXPLICIT_FLUSH flag set.

dri2_resource_get_param() is called from two different places right now.
Only one of them adds the EXPLICIT_FLUSH hint to the handle usage, which
may disable the optimizations provided by this hint without a reason.
Make sure to always add this hint when appropriate.

This is the combination of two simplifications I spotted while
researching some other issue:
1. We can use nir_const_value_as_uint to save some conditionals
2. We can unify the vector and scalar code-paths to reduce some
duplicated logic.
While we're at it, switch to using NIR_MAX_VEC_COMPONENTS rather than a
dynamic array size on the stack, because that tends to generate better
code.

acquire a reference on the AHB. So if we layer the exportable allocation
on top of AHB allocation and AHB import, we must release an AHB

feedback, or point sprites are used), we only need to link once. Now
that pan_pool supports both owned and unowned modes, we have the
