a1a365e818 broadcom/compiler: Allow spills of temporaries from TMU reads
Since spills and fills use the TMU, special care has to be taken to
avoid putting one between a TMU setup instruction and the corresponding
reads or writes. This change adds logic to move fills up and move spills
down to avoid interrupting such sequences.

This allows compiling 6 more programs from shader-db. Other stats:

total spills in shared programs: 446 -> 446 (0.00%)
spills in affected programs: 0 -> 0
helped: 0
HURT: 0

total fills in shared programs: 606 -> 610 (0.66%)
fills in affected programs: 38 -> 42 (10.53%)

total instructions in shared programs: 19330 -> 19363 (0.17%)

25066eb20a v3dv/device: do nothing when asked physical device pci bus properties
When calling GetPhysicalDeviceProperties2 we were ignoring and logging
the structures for extensions not supported. But for the case of
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PCI_BUS_INFO_PROPERTIES_EXT we
already know that we are not going to support it, so let's just do
nothing (not even logging) when passed.

09b2bd1df9 broadcom/compiler: remove v3d_fs_key depth_enabled field.
It is not used right now, so keeping it adds some noise/confusion.

So far configuring Z test are done through the CFG_BITS. See
v3dX(emit_state) at v3dx_emit.c for v3d, and pack_cfg_bits at
v3dv_pipeline.c for v3dv. There flags like z_updates_enable and others
are filled up.

That key field seems like a leftover coming from using vc4 as
reference, as that driver defines and uses a field with name name.

7d6609e70d v3dv: fix occlusion query inheritance in secondary command buffers
If a secondary command buffer has occlusion query inheritance then
draw calls recorded in it should update an active occlusion query
counter started in the primary command buffer.

If executing the secondary in a primary required to emit jobs and
not just a branch instruction, then we might need to create a new
job for the primary as well, and in that case we would lose the
occlusion query state, so we need to re-emit it at that point so
any additional draw calls recorded into the secondary that is being
executed continue to update the counter.

e07c546763 v3dv/format: use XYZ1 swizzle for three-component formats
So far for the formats E5B9G9R9_UFLOAT_PACK32 and
B10G11R11_UFLOAT_PACK32 we were using a XYZW swizzle. But from Vulkan
spec those are three-component, without alpha, formats. So we should
use XYZ1 instead, as we were already doing for other three-component
formats.

Curiously the only case where this raised a problem were when using
clamp to border with transparent black. This change allows us to
remove the code that handled only that specific case.

79cd22b889 v3dv: enable alphaToOne feature
This is another case of a feature that is implemented in the compiler
and that only required that we set the shader key properly from the
pipeline state, which we were already doing.

I verified we pass the tests in dEQP-VK.pipeline.multisample.alpha_to_one.*
(we only support 4x multisampling, so we can only pass a single test there),
however, the tests seem to have a bug by which they always pass, even if
the driver doesn't actually implement alpha to one correctly. I submitted
a fix to Khronos and verified that we also pass the fixed tests (and that
we failed them if we don't actually set te shader key correctly).

666817ce84 v3dv: grow meta descriptor pool dynamically
Our blit shader path allocates a descriptor pool to create
combined image sampler descriptors for blit source images. So
far, we had sized this pool statically and the driver would
fail if we ever need to allocate more descriptors than that.

With this change, we switch to using a dynamic allocation
mechanism instead where we allocate as many pools as we need to
meet descriptor set allocation requirements for the command buffer.

Also, every time a new pool needs to be created, we double its
size (up to a limit), so we can start small and avoid wasting
memory for command buffers that only have a small number of blits,
while trying to keep allocation overhead low for command buffers
that record a lot of blits.

v2: use existing framework for automatic destruction of private
    driver objects to free allocated pools.

been smoke tested, but it seems to be working correctly, as expected.

40788be134 v3d/compiler: fix BGRA vertex attributes for vec2/float size.
We don't natively support BGRA format, instead we handle these
as RGBA and we lower the loads to swap components R and B.

However, the driver emits VPM loads based on the size of the
input variables so when we have a vec2 or float BGRA input,
it would only emit VPM loads for components 0 and 1, which is
not correct since we emit a load of component 2 to swap with
component 0.

0a4fc19605 v3dv: skip unnecessary tile loads when blitting

blitting only a subset of the pixel components in the image

case we need to preserve the components we are not writing.

There is a corner case where some times we create framebuffers
that alias subregions of a larger image. In that case the edge
tiles are not padded and we can't skip the loads.

c7814bcde3 v3dv: fix blit path for copies from 3D compressed images
The aliasing we were using was not always correct. Particularly,
for 3D images, the simulator would complain about image strides
not being large enough in some cases.

This patch fixes this by aliasing both src and dst images and
carefully choosing the alias dimensions taking into account the
format chosen for the copy and the ratio of block sizes between
both images.

Playing a bit with the image dimensions used by the relevant CTS
tests we confirmed this works well for all tile layouts (lineartile,
ublinear1/2 and UIF).

This fixes all CTS tests involving 3D image copies from compressed
formats without needing to force UIF layout for all compressed
images (which would actually not work for all image sizes either).

1e81bb05ae v3dv: implement workaround for GFXH-1461
If a subpass clears one aspect of Depth/Stencil but loads the other
the clear might get lost. Fix this by emitting the clear as a draw
call instead of relying on the TLB clear.
