https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250802 --- Comment #49 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Peter Grehan from comment #48) I remember that starting with SandyBridge, Intel GPUs have a window in their membar that translates accesses to mchbar. Quick look at the docs suggests that Skylake still does this. So do you think that 1:1 gpa:hpa mapping for pass-through would be helpful ? Do you remember a title of the talk, or have an url ? -- You are receiving this mail because: You are the assignee for the bug.help
