I want to function hooking on arm64 but the code build fail

ilammy commented 2 years ago

Uh... Yeah, I've tested this only on x86_64 since that's the hardware I have. Sorry, I was not an expert at arm64 at the time and I'm not one now either. I believe it has a chance at working on arm64 though, if you let the code compile there, ftrace is a generic framework after all.

Have you tried removing the CONFIG_X86_64 guard check?

hey, I added ARM64 support in #15. some of the flags were not compatible with arm cpu. also, on the ARM64 architecture, the equivalent of regs->ip on x86 would be regs->pc (instruction pointer to program counter).
