I've started on this one

Branch is up at vc4-discard-jump. Didn't get any measurable wins from it on 3DMMES.

From your linked bug reports, it sounds like you're not using the Mesa driver at all ("Found brcmEGL and brcmGLES library filesfor rpi platform at /opt/vc/lib/" and your discussion of...

Can you open your own bug report with your specific issue with the app using full KMS mode, and how to reproduce it?

I would recommend hacking out subtests from the CTS test until you get down to the minimal testcase that will hang the GPU. Then, since you've got weird viewport stuff...

Looks like a reasonable start. Note that `src/gallium/driivers/vc4/kernel/`is just copies of the kernel code used for the software simulator, and you'll need to modify your actual kernel drivers/gpu/drm/vc4/ code :)...

Yeah, feel free to work against downstream rpi's kernel. The validation code hasn't changed in so long that we should be able to apply any patches that you send (to...

Yeah, I'd forgotten that we had the format in the key already. Ideally we would have our texturing unpacks be in NIR, but I haven't done that yet. If we...

You mean packing for TLB writes? Yeah, I moved that to NIR, and some sort of similar logic might work for texturing. (It's kind of weird because we don't get...

WIP moving the texture unpacking to NIR for v3d, should be straightforward to use in vc4 too: https://gitlab.freedesktop.org/anholt/mesa/commits/v3d-lower-tex-results
