Alejandro Piñeiro 7c9b40effa v3dv/pipeline: handle properly OUT_OF_HOST_MEMORY error when allocating p_stage
So far we were just assuming that it would work (so we could try to
access a NULL pointer), and not freeing it properly.

Fixing that was somewhat messy due pipeline_compile_graphics using a
temporary array and then update the internal pipeline stages. As we
are here we just removed the array and simplified
pipeline_compile_graphics code.

Fixes following tests:
  dEQP-VK.api.object_management.alloc_callback_fail.graphics_pipeline
  dEQP-VK.api.object_management.alloc_callback_fail_multiple.graphics_pipeline

Alejandro Piñeiro d64ff26563 v3dv/pipeline: pre-generate more that one shader variant
In order to reduce the number of shader builds after pipeline creation
(that ideally shouldn't happen) we pre-generate two shader variants at
pipeline creation time. In addition to the default one, that set the
return size for all texture to 16 bit, we build another variant
setting the return size for all textures to 32-bit. cmd buffer selects
the latter if any of the textures requires 32bit.

So we are using an all 16-bit return size or an all 32-bit return size
variants. This could be slightly improved by pre-generating return
size combinations if the texture number is below a threshold. But that
would require more space, and bigger pipeline creation time, so would
need to be evaluated.

Alejandro Piñeiro a87d2c7806 v3dv/pipeline: when looking for a variant, check first current variant
So far, when checking for a variant fulfilling a specific v3d key, we
were checking the caches, and if that failed, we compiled a new
variant, and update the current variant.

But we could check first if the current variant fullfils that. This
was not really problematic so far, as checking on the caches was fast,
but now that we could be without any kind of shader cache using
V3DV_ENABLE_PIPELINE_CACHE, it is far better to check first current
variant.

Without this vkQuake3 at 720p drops to 1fps when disabling the cache.

Alejandro Piñeiro 35381a4696 v3dv/pipeline_cache: add default pipeline cache
That it would be used as fallback. Three advantages:

  * Having a cache for user operations even if the user doesn't
    provide it.

  * Having a cache for internal operations. v3dv_meta_copy creates
    pipelines for some copy path, so it is interesting to have them
    cached.

  * Testing: so now the pipeline cache is tested by more CTS tests.

As any other pipeline cache, it can be disabled with the
V3DV_ENABLE_PIPELINE_CACHE. It was suggested that would make sense to
have a specific envvar for the default pipeline cache, but for now
just one envvar is enough.

Alejandro Piñeiro 48a64f28c2 v3dv/pipeline: provide a shader_sha1 to private ShaderModules
So far for private pipelines we were creating dummy shader modules
where we directly provided the nir shader. But for the pipeline cache
we were using the SPIR-V to generate part of the cache key sha1.

The main use case for private pipelines are meta_copy/clear. Those nir
shaders depend on parameters like the format etc, so we use directly
the serialized form of the NIR shader to generate the sha1.

The other case are the no-op fragment shader that we need to provide
if no fragment shader is defined by the user. For that case we can
just use the default shader name, as the no-op shader is always the
same.

This is required as we plan to add a default pipeline cache, that
would include our private shaders too.

Alejandro Piñeiro a00fe4cb0c v3dv/pipeline_cache: cache v3dv_shader_variants
This also includes being able to serialize them as part of
GetPipelineCacheData and to deserialize it as part of
CreatePipelineCache.

So now we can also upload the assembly of the variant as part of the
PipelineCache creation.

Note that from all this the tricky part was the prog_data
serialization. v3d_compile allocates and fill a new prog_data, with
rzalloc. Among other things because it also allocates internally the
uniform list. So we needed to replicate that when deserializating the
prog_data. Ideally we would like to avoid that, and allocate as much
resources as possible using vk_alloc, but that would mean a somewhat
deep change on the v3d_compiler, that we want to avoid as much
possible for now.

Alejandro Piñeiro 2326d5bc04 v3dv/pipeline_cache: cache nir shaders
Heavily based on anv nir caching. One of the bigger difference is that
we don't create the nir shader using a ralloc_context local to the
main compile graphics method. On anv, after compiling the shader, they
discard the nir shader. We need it as we could need it to build shader
variants later.

As anv, we introduce a environment variable to disable the cache:
  V3DV_ENABLE_PIPELINE_CACHE

By default is enabled. The main purpose for this envvar is debugging,
in order to provide a easy way to discard a bug on the cache.

It is pending to serialize/deserialize the NIR shaders as part of
GetPipelineCacheData and PipelineCacheCreate. We also plan is to cache
too shader variants. We would do that on following patches.

anything yet. That would be tackle on following patches.

Note that this no-op cache got all the specific pipeline_cache and
pipeline.cache tests passing on the rpi4.

The following tests are still crashing when using the simulator:
 dEQP-VK.synchronization.internally_synchronized_objects.pipeline_cache_compute
 dEQP-VK.synchronization.internally_synchronized_objects.pipeline_cache_graphics

But those are an issue of synchronization tests on the simulator, and
not related with the pipeline cache itself. In general synchronization
tests should be tested on the rpi4.

Iago Toral Quiroga 47e02a2ef1 v3dv: add a fast path for vkCmdClearAttachments
Since vkCmdClearAttachments executes inside a render pass, we would
benefit from converting it to a draw within the current subpass job to
improve batching and avoid expensive tile load/store operations.

This can dramatically improve performance for applications using this
command, however, we can only use this if we are clearing the base
layers of framebuffer attachments, since otherwise we would need to
use layered rendering, which we don't support yet.

This improves vkQuake3 performance dramatically (almost 100%

Iago Toral Quiroga 97891898c3 v3dv: only use per-buffer clear bit for cases were we are already storing
This bit is helpful if we already need to store the buffer, but otherwise
we should not emit the store only to get the clear, we can use the global
clear packet for that and save us an expensive tile buffer store operation.

Also, we have not been using the per-buffer clear bit for depth/stencil
stores since "v3dv: fix depth/stencil clears on hardware", so we should
never been considering clearing needs to flag stores.

This improves vkQuake performance somewhere between 5%-15% by allowing
us to skip the store of the depth attachment.

Iago Toral Quiroga add8778638 v3dv: ignore stencil load operation if attachment format doesn't have stencil
This gets vkQuake to render correctly, which creates render passes with
stencil load operations even when the depth/stencil attachment format
doesn't have a stencil aspect. While this is a bit weird, it seems to
be allowed by the spec:

   "If the format has depth and/or stencil components, loadOp and storeOp
    apply only to the depth data, while stencilLoadOp and stencilStoreOp
    define how the stencil data is handled."

In our case we were not ignoring it and this was causing that we emitted a
Z buffer load that seemed to clobber the Z clear, preventing all draw calls
from passing the depth test.

While we are at it, also change the depth/stencil store operation (which
was already handling this scenario correctly) to use the format of the
render pass attachment description rather than the underlying image
format.
