ARM64対応
NVIDIAのGPUは、ARM64対応されています。ARM64対応が分かるコードは、ここ です。一部、以下に引用します。
switch(AARCH64_VENDOR_PART_NUMBER(impl, part)) { case AARCH64_VENDOR_PART(NVIDIA, DENVER_1): pSys->cpuInfo.type = NV0000_CTRL_SYSTEM_CPU_TYPE_NV_DENVER_1_0; break; case AARCH64_VENDOR_PART(NVIDIA, DENVER_2): pSys->cpuInfo.type = NV0000_CTRL_SYSTEM_CPU_TYPE_NV_DENVER_2_0; break; case AARCH64_VENDOR_PART(NVIDIA, CARMEL): pSys->cpuInfo.type = NV0000_CTRL_SYSTEM_CPU_TYPE_ARMV8A_GENERIC; break; /* * Applied Micro is now Ampere computing, and the Ampere eMag * vendor/part ids are the same as AMCC XGENE */ case AARCH64_VENDOR_PART(AMCC, XGENE): case AARCH64_VENDOR_PART(ARM, CORTEX_A76): case AARCH64_VENDOR_PART(MARVELL, THUNDER_X2): case AARCH64_VENDOR_PART(HUAWEI, KUNPENG_920): case AARCH64_VENDOR_PART(ARM, BLUEFIELD): // The Neoverse N1 is the same as Gravitron case AARCH64_VENDOR_PART(ARM, GRAVITRON2): case AARCH64_VENDOR_PART(FUJITSU, A64FX): case AARCH64_VENDOR_PART(PHYTIUM, FT2000): case AARCH64_VENDOR_PART(PHYTIUM, S2500): case AARCH64_VENDOR_PART(AMPERE, ALTRA): case AARCH64_VENDOR_PART(MARVELL, OCTEON_CN96XX): case AARCH64_VENDOR_PART(MARVELL, OCTEON_CN98XX): case AARCH64_VENDOR_PART(ARM, CORTEX_A57): pSys->cpuInfo.type = NV0000_CTRL_SYSTEM_CPU_TYPE_ARMV8A_GENERIC; break; default: pSys->cpuInfo.type = NV0000_CTRL_SYSTEM_CPU_TYPE_ARMV8A_GENERIC; portDbgPrintf( "NVRM: CPUID: unknown implementer/part 0x%x/0x%x.\n", impl, part); portDbgPrintf( "The NVIDIA GPU driver for AArch64 has not been qualified on this CPU\n" "and therefore it is not recommended or intended for use in any production\n" "environment.\n"); break; } DecodeAarch64Cache(pSys);
- Marvell
- Hauwei
- Ampere Computing (AMCC)
- NVIDIA : Bluefield
- AWS : Gravitron2 (Graviron)
- Fujitsu : A64FX
- Phytium
などがサポートされています。Phytiumは中国の会社です。A64FXもサポートしているんですね。PCIe Gen4 のポートに付けちゃうんですかね。
