https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222234 --- Comment #6 from Mark Millard <markmi@dsl-only.net> --- Created attachment 186517 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D186517&action= =3Dedit Example patch for sys/arm64/arm64/identcpu.c 's sev instruction use Beyond the release_aps use of SEV during boot I found a SEV use in identcpus.c . So this is a possible patch for that (for the same issue of SEV not being timed relative to memory updates). I do not claim either patch has the optimal form of dsb ??? instruction, just one that seems (more then?) sufficient. --=20 You are receiving this mail because: You are the assignee for the bug.=
