https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218262 --- Comment #5 from Greg V <greg@unrelenting.technology> --- (In reply to Conrad Meyer from comment #3) Oh. FIDVID is for K7 processors, Family 17h is a newer generation, K8. That's why AMD doesn't mention FIDVID in the docs. Anyway… This interesting Linux patch https://lwn.net/Articles/443375/ unified AMD and Intel p-state handling, they basically just select between functions that write to different MSRs. And they do write to 0xc0010062. --- I tried making the loop longer (1000 iterations) and writing in the loop, still it doesn't read the right value :( -- You are receiving this mail because: You are the assignee for the bug.help
