qazalandGitHub 4445f50356 viz: variable duration rdna barriers (#15277) 
* viz: variable length rdna barriers

* work

* tiny changes

* simple wave simd test

* small wave sync test

* good multi barrier bug find

* simple fix

* wave_sync asserts

* rdna4 work

* more rdna4

* find more bugs in my model

* it's so much simpler

* wave_sync tests duration

* r4

* should just call this rdna4

SQTT Profiling

Getting SQ Thread Trace

VIZ=2 to enable SQTT profiling.

SQTT_ITRACE_SE_MASK=X to select shader engines for instruction tracing, -1 = all, 0 = disabled, >0 = SE bitmask, default 0b11.

SQTT_BUFFER_SIZE=X to change size of SQTT buffer (per shader engine, 6 SEs on 7900xtx) in megabytes, default 256.

Viewing the traces

  • Web UI: tinygrad/viz/serve.py
  • Command line: python -m tinygrad.renderer.amd.sqtt
