NV40:G80 signals

Introduction

NV40 generation cards have the following counter domains:

  • NV40 generation cards without turbocache:
    • 0: host clock
    • 1: core clock [PGRAPH front]
    • 2: geometry[?] clock [PGRAPH back]
    • 3: shader clock
    • 4: memory clock
  • NV40 generation with turbocache that are not IGPs:
    • 0: host clock
    • 1: core clock [PGRAPH front]
    • 2: shader clock
    • 3: memory clock
  • NV40 IGP:
    • 0: host clock
    • 1: core clock [PGRAPH probably]
    • 2: core clock [shaders probably]
    • 3: unknown, could be the memory interface
