  "message": "Add fallback for ARM Windows fp16 detection. (#348)\n\nBackground: On a Windows ARM system, I observed that `cpuinfo_has_arm_fp16_arith()` started to return false after upgrading to a more recent cpuinfo version.\n\nIn #333, the initialization of `cpuinfo_isa.fp16arith` was updated to use `IsProcessorFeaturePresent(PF_ARM_V82_FP16_INSTRUCTIONS_AVAILABLE)`. I suspect that this is not supported on older Windows versions.\n\nThis change adds a fallback path to set `cpuinfo_isa.fp16arith` the old way.\nhttps://github.com/pytorch/cpuinfo/blob/d3a86a813e2bb49d1eb5841ec12e2b135867ab98/src/arm/windows/init.c#L205-L208",
