This question is mostly for Gabe. In the ROCm runtime we see some inline asm
for specific CPUID functions. They first use CPUID to determine the name string
for the processor, and when it seems the "M5 Simulator" as the vendor it
defaults to Intel and sends along the CPUID request with the Intel-specific ID
for cache config descriptors. The ID used by Intel is different than is used by
AMD for the same function.
I am just wondering what your thoughts are about implementing these functions.
Do we implement the CPUID functions for only one vendor? Is there a way to make
it configurable?
Currently I am not bothering to implement it, I am simply returning {0x0, 0x0,
0x0, 0x0} and issuing a warn (in cupid.cc), but I still need to add the
particular ID to the StandardCpuidFunction enums in order for it to be
considered in the switch statement.
