问题 In Windows X86, the CPU brand can be queried with cpuid intrinsic function. Here is a sample of the code: #include <stdio.h> #include <intrin.h> int main(void) { int cpubrand[4 * 3]; __cpuid(&cpubrand[0], 0x80000002); __cpuid(&cpubrand[4], 0x80000003); __cpuid(&cpubrand[8], 0x80000004); char str[48]; memset(str, 0, sizeof str); memcpy(str, cpubrand, sizeof cpubrand); printf("%s\n", str); } What is the alternative of this in Windows ARM64? 回答1: Not a way to get name directly from the CPU

问题 Does anyone know how to publish a .NET Core 3.0 application for ARM64? I can only select "linux-arm" but no "linux-arm64". Setting linux-arm in combination with x64 also doesnt work. It says the settings are not compatible. As stated here it should already be supported: https://github.com/dotnet/core/blob/master/release-notes/3.0/3.0-supported-os.md 回答1: The linked article points to the supported OSs, not the list of runtime identifiers. An explanation of an RID and a list of common ones can
