956d961339 panfrost: Use first_tiler to check if tiling is needed
If there is a preload job needing tiling, but no other jobs, then
first_tiler will be set but not tiler_dep.

Fixes faults when two depth-only (stencil is reloaded) clears are done
in a row.

5e88a1caca panfrost: Performance configuration
Configure a panfrost performance structure with tables of categories and
counters for the current product id. An array for storing counter values
read from the GPU is also managed by this structure. A generic read
function can be used to retrieve the value of a counter from the conter
values array.

v2: Generate tables instead of calling register functions.
v3: Simplify counter read function and `pan_gen_perf.py` write method.
v4: Accumulate counter values from all cores.
v5: Wrap `STATIC_ASSERT`s within unused functions.

2f4b5a4ebe panfrost: Abort on faults in SYNC mode
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.

af78f52493 panfrost: Only link varyings once in good conditions
If the varying descriptors will always be the same for a given shader
variant (certainly true if none of separable shaders, transform
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
flexibility to reuse the code path for both allocation strategies.

2c2cf0ecfe panfrost: Streamline varying linking code
Refactor all the linking code with the following objectives:

* Remove linking magic (especially around XFB)
* Cleaner code (obviously)
* Less stage coupling (in case someone ever implements geom/tess)
* Decouple ATTRIBUTE from ATTRIBUTE_BUFFER to enable optimizations

The main hack remaining is doing precision linking here to workaround
linking previously used.

shader-db stats aren't as bad as they appear at first blush, since the
added cycles are from added if-else branches (and only one side of the
if is taken on Midgard, which does no warping*).

a89bc59980 pan/mdg: Fix spills to TLS
LOCAL_STORAGE.zw is workgroup local memory, whereas LOCAL_STORAGE.xy is
thread local memory. Likewise PC_SP.zw is the stack pointer, which is
initialized to (LOCAL_STORAGE.zw + offset) but is modifiable by the
shader. Panfrost doesn't modify the s tack pointer, and the register
allocation logic assumes a zero offset, so let's always spill to thread
local memory = LOCAL_STORAGE.xy, as was intended by Italo's cleanup.

This is visible on any shader that spills. Compute shaders aren't
advertised yet, so WLS will be null, causing a fault like the following
(reproduced on Mali T860 with the glyphy trace):

77d0498913 panfrost: Fix major flaw in BO cache
BOs in the cache are chronological, so we try oldest BOs first. That
means if we find the oldest BO is busy, likely every BO is busy, and we
should bail early. This dramatically reduces the useless cycles spent in
bo_wait.

I studied the BO cache of the following drivers, all of which handle
this correctly: iris, lima, etnaviv, freedreno, vc4, v3d, v3dv.

6b036d1350 panfrost: Relax the stride check when importing resources
Imported resources will not necessarily have their line stride aligned
on 64 bytes, and things prove to work just fine even on Bifrost, so
let's relax the condition and drop the comment stating that Bifrost
needs pixel lines to be aligned on 64 bytes.

e1959f0f59 panfrost: Add GPU IDs for G52 1-Core-2EE (RK3568/RK3566)
Rockchip SoCs RK3566 and RK3568 have a Gondul with
one shader core and two execution engines, with product ID 0x7402.

Quoting the datasheet:

Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency

To distinguish it from other variants of G52, we agreed
to call this "G52L", L is for Little.

01ef56a7e4 pan/mdg: Use smaller LD_UNIFORM instructions
If we only read 8 bytes from a UBO, we need to use LD_UNIFORM.64 as
opposed to LD_UNIFORM.128. In addition to probably being faster, this
fixes a buffer overrun manifesting as MMU faults with source ID
0x500/0x600/0x700, visible in WebGL Aquarium.

This is essentially the same patch as 616394cf31 ("pan/mdg: Use
appropriate sizes for global loads/stores"), only this is for UBOs where
that was for SSBOs.

Before enabling PACKED_UNIFORMS, this bug was not visible since we could
guarantee the UBO size was a multiple of 16. We no longer have that
invariant, and in rare cases the last 8 bytes of the last 16-byte slot
of a mapped uniform buffer would overrun the BO and trigger a fault,
even if the result is unused.
