Windows ARM64 support #30

Closed Myriachan closed 1 year ago

Myriachan commented 4 years ago

Windows ARM64 isn't currently supported.

On Windows ARM64, you can use GetLogicalProcessorInformationExW like x86. To detect hardware features, you can use IsProcessorFeaturePresent. (Check WinNT.h in the latest SDK, because some of them aren't documented on MSDN yet.) Also, the __try trick could also work.

The vendor and processor model are the VendorIdentifier and Identifier values of HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0. (On x86, these registry fields are copies of the vendor and brand string from cpuid. But on ARM, there's no user-mode way to query this.)
