C++ (Cpp) getVGPRAllocGranule Examples

Example #1

File: AMDGPUBaseInfo.cpp Project: Tauril/llvm

unsigned getMaxNumVGPRs(const MCSubtargetInfo *STI, unsigned WavesPerEU) {
  assert(WavesPerEU != 0);

  unsigned MaxNumVGPRs = alignDown(getTotalNumVGPRs(STI) / WavesPerEU,
                                   getVGPRAllocGranule(STI));
  unsigned AddressableNumVGPRs = getAddressableNumVGPRs(STI);
  return std::min(MaxNumVGPRs, AddressableNumVGPRs);
}

Example #2

File: AMDGPUBaseInfo.cpp Project: BNieuwenhuizen/llvm

unsigned getMaxNumVGPRs(const FeatureBitset &Features, unsigned WavesPerEU) {
  assert(WavesPerEU != 0);

  unsigned MaxNumVGPRs = alignDown(getTotalNumVGPRs(Features) / WavesPerEU,
                                   getVGPRAllocGranule(Features));
  unsigned AddressableNumVGPRs = getAddressableNumVGPRs(Features);
  return std::min(MaxNumVGPRs, AddressableNumVGPRs);
}

Example #3

File: AMDGPUBaseInfo.cpp Project: Tauril/llvm

unsigned getMinNumVGPRs(const MCSubtargetInfo *STI, unsigned WavesPerEU) {
  assert(WavesPerEU != 0);

  if (WavesPerEU >= getMaxWavesPerEU())
    return 0;
  unsigned MinNumVGPRs =
      alignDown(getTotalNumVGPRs(STI) / (WavesPerEU + 1),
                getVGPRAllocGranule(STI)) + 1;
  return std::min(MinNumVGPRs, getAddressableNumVGPRs(STI));
}
