https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218262 --- 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=E2=80=A6=20 This interesting Linux patch https://lwn.net/Articles/443375/ unified AMD a= nd Intel p-state handling, they basically just select between functions that w= rite to different MSRs. And they do write to 0xc0010062. --- I tried making the loop longer (1000 iterations) and writing in the loop, s= till it doesn't read the right value :( --=20 You are receiving this mail because: You are the assignee for the bug.=
