Rpi2/3 crash (GLES2?) #357

Open dmrlawson opened 3 years ago

From https://github.com/libretro/Lakka-LibreELEC/issues/1332

Since some point in the past the core has stopped working properly on rpi 2 and 3.

From my own testing I've found Diddy Kong Racing displays the first screen then crashes. The only message in the logs after the normal startup is:

unknown NIR ALU inst: vec1 32 ssa_134 = umin ssa_59, ssa_61

I mentioned it in Discord a while ago and the shader cache was mentioned as a potential culprit. AFAIK it's disabled on these platforms and there's no entry in the core options for it.

I understand it might be a Mesa issue but I'm not really sure where to go from here.

Hi,

You may try to add apitrace in addition to backtrace for the bug report as specified in the mesa doc ? If needed an example for launching apitrace.
