@thekhronosgroup is there an easy option for the general public to have access to issues in the Khronos issue tracker for #Vulkan ? Within #Mesa3d I always stumble across links like https://gitlab.khronos.org/Tracker/vk-gl-cts/-/issues/6580 that I can't view.
(Yes, some stuff needs to be internal, but GitLab does allow internal notes/comments, why not use that and push the "normal" stuff out into the open?)
@austriancoder Wow, great to hear! Although I do not understand all the technical details of what you are working on, I'm following your work with high interest. And I'm not the only one :-)

I am transforming a ~7month old wip branch into something upstream-able. Lot more GLES3 tests are passing with these commits. But I need to spend some more hours to test 2-3 different GPU models, before I will create a MR.
dEQP-GLES31.functional.image_load_store.* 699/747 pass
With the help of some freshly reverse-engineered ISA opcodes :)
Itโs always a pain to emulate missing hardware features.
dEQP-GLES3, old etnaviv compiler vs new one:
+6140 passes, โ3004 crashes. ๐
I built infrastructure to validate ISA-specific behavior on hardware against a `Foldable` CPU reference - the idea is straight out of NAK by @gfxstrand . Write the per-opcode reference once, run a matrix of cells (src mods ร swizzles ร write masks) on the GPU and compare.
It saved me so much guesswork about how each ISA instruction behaves with input values and rounding modes - hello subnormal IEEE 754 pain.
I should have started this earlier.
You've probably seen kmscube before - but every screenshot of it is a milestone someone reached. Last night I hit one of those moments, after many years (again).
For the past months I shifted focus away from GLES3 to some foundation work that had to be done.
On the photo: kmscube running on the long-in-development new compiler backend, used for both the vertex and fragment shader.
