[Mesa-dev] [PATCH v2 00/28] ARB_gl_spirv: v2 ubo/ssbo support, plus CTS goodness

[Alejandro Piñeiro]

Hi,

this is the second version of the ubo/ssbo support for ARB_gl_spirv
series. Differences compared with v1:

  * Rebased against today master.

  * Patch "nir/linker: use only the array element type for array of
    ssbo/ubo" got a proper spec quote.

  * Two extra patches are included. They are not strictly related to
    ubo/ssbo. Just when I sent v1, I checked how many patches from our
    development branch were required to pass all the ARB_gl_spirv
    tests. And they were just two. So although initially the plan was
    sending them as part of a different series, we decided to send it
    now, basically because "passing all the CTS tests" is a nice
    checkpoint, and it would be nice to get it on master. Having said
    so, note that "passing all the CTS tests" is not "extension is
    production ready", so we would keep sending series/patches before
    propose to enable it.

And something that was not mentioned on v1 cover-letter, but later on
the review thread: this series doesn't include the support for array
of arrays of ubo/ssbo. That will be sent later on a different series.

The v1 was sent here:
   https://lists.freedesktop.org/archives/mesa-dev/2018-September/205278.html

This series can be found on this branch:
   https://github.com/Igalia/piglit/tree/arb_gl_spirv-series5-ubo-ssbo-v2

And can be tested with this piglit series:
   https://github.com/Igalia/piglit/tree/arb_gl_spirv-series5-ubo-ssbo-v2

And as mentioned, with this series would pass the CTS ARB_gl_spirv
tests on i965.
