[Mesa-dev] [PATCH] mesa: define nir_spirv_supported_capabilities

[Alejandro Piñeiro]

Until now it was part of spirv_to_nir_options. But it will be used on
the implementation of ARB_gl_spirv and ARB_spirv_extensions, and added
to the OpenGL context, as a way to save what SPIR-V capabilities the
current OpenGL implementation supports.
---

We are sending this commit in advance of a v3 of the initial gl_spirv
and spirv_extensions support series. The issue is that lately there
were a lot of activity on the spirv/spir_to_nir code base, and we are
being fixing rebase conflicts constantly. Getting this commit on
master would make things easier.

FWIW, this patch is similar to one that Ian Romanick already granted
Rb, but that was dropped after all the mentioned changes:

/**
* Constants which may be overridden by device driver during context creation

[Pierre Moreau]

Hello Alejandro,

As far as I understand, nir_spirv_supported_capabilities is being filled in by
the driver and then fetched by the API entrypoint to check the capabilities
required by the SPIR-V binary given as input. And this is done regardless of
the input IR used by the driver, be it NIR, LLVM IR, TGSI or others. So
couldn’t it be just named spirv_supported_capabilities? Unless it also reflects
the capabilities supported by the IR being used.

I guess nir_spirv_supported_capabilities could be extended later on to also add
capabilities specific to OpenCL when clover reaches OpenCL 1.2 support (and can
start accepting SPIR-V binaries as input through the cl_khr_il_program
extension), or would it be better to have a separate one for OpenCL?

I haven’t had time to look at the whole gl_spirv series yet, so I am sorry if
this is something that has already been brought and answered in that thread.

Regards,
Pierre

anyone interested on review the commit, I will use that name.

Ugh... I just now got around to looking at this and saw that it went
in mtypes.h.  Can we please move it?  We've worked very hard to keep
the Vulkan driver from having to pull in any GL headers and data
structures and now a fairly core piece lives in mtypes.h.

Hmm, sorry for not waiting for more feedback. This is the second
reviewed patch that modify mtypes.h, so I assumed that it was fine.

Additionally, I didn't rename it as Ian's review didn't ask to, but both
Timothy and Pierre prefer a more general "spirv_supported_capabilities".
So how about this?:
   * Rename it to spirv_supported_capabilities
   * Move it to compiler/spirv/spirv.h (would need to add #include
<stdbool.h> due the booleans on the struct there)
   * Add a "compiler/spirv/spirv.h" include on mtypes.h

I already have the patches locally, so if you agree with this, it is
just about sending them.

[Alejandro Piñeiro]

To avoid any vulkan driver to include the GL mtypes.h. Renamed as
eventually this could be used by drivers not using nir.
---

Sending the proposed alternative in advance, so if Jason agrees, it is
just about Rb it.

The include on v1 was a leftover, when I tested if adding the

needed on this patch, but on a following one.

Sorry for the noise.

We shouldn't add things to spirv/spirv.h. That's a header we pull in from
Khronos so we really shouldn't be touching it. Other possibly reasonable
options include:

1) compiler/shader_info.h
2) A new spirv/spirv_capabilities.h header
3) Add a couple of predeclarations to spirv/nir_spirv.h, drop the nir.h
include, and put it there.

I think option 1 is probably the most sane. It's not really shader_info
but it's kind-of like that.

Hello Alejandro,
As far as I understand, nir_spirv_supported_capabilities is being filled in by
the driver and then fetched by the API entrypoint to check the capabilities
required by the SPIR-V binary given as input. And this is done regardless of
the input IR used by the driver, be it NIR, LLVM IR, TGSI or others. So
couldn’t it be just named spirv_supported_capabilities? Unless it also reflects
the capabilities supported by the IR being used.
I guess nir_spirv_supported_capabilities could be extended later on to also add
capabilities specific to OpenCL when clover reaches OpenCL 1.2 support (and can
start accepting SPIR-V binaries as input through the cl_khr_il_program
extension), or would it be better to have a separate one for OpenCL?

I expect that over time there will be overlap between SPIR-V
functionality exposed in OpenCL, Vulkan, and OpenGL extensions. There
already are some cases of this. Given that, I think having a single
master list of supported capabilities makes sense.

Post by Pierre Moreau
I haven’t had time to look at the whole gl_spirv series yet, so I am sorry if
this is something that has already been brought and answered in that thread.
Regards,
Pierre

Post by Alejandro Piñeiro
Until now it was part of spirv_to_nir_options. But it will be used on
the implementation of ARB_gl_spirv and ARB_spirv_extensions, and added
to the OpenGL context, as a way to save what SPIR-V capabilities the
current OpenGL implementation supports.
---
We are sending this commit in advance of a v3 of the initial gl_spirv
and spirv_extensions support series. The issue is that lately there
were a lot of activity on the spirv/spir_to_nir code base, and we are
being fixing rebase conflicts constantly. Getting this commit on
master would make things easier.
FWIW, this patch is similar to one that Ian Romanick already granted
