https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250802 Peter Grehan <grehan@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |grehan@FreeBSD.org --- Comment #6 from Peter Grehan <grehan@FreeBSD.org> --- I just commented on the review: that patch shouldn't be needed (a comment on why the assert is there could help I guess). A possibility here is that the 64-bit PCI that bhyve reserves is out of physical address range for that model CPU. The fix for this is to make the = base of this region dynamic after a CPUID to determine the max phys addr lines. Another fix that Robert mentioned is to relax the overly-small 32MB restric= tion on placing mmio bars in the PCI hole below 4G. It can be 256MB without any issues, and 512MB with sorting of BARs. --=20 You are receiving this mail because: You are the assignee for the bug.=
