But the latter seems like overkill for just > hv_get_raw_timer(), so I'm OK with the #ifdef. We surely can have asm/hyperv_timer.h but TBH: >> static inline notrace u64 >> hv_read_tsc_page_tsc(const struct ms_hyperv_tsc_page *tsc_pg, u64 *cur_tsc) >> { hv_read_tsc_page_tsc() does not look architecture agnostic either. TSC is pretty x86 specific :) Thanks, tglx
