Subject: [PATCH 0/2] KVM: x86: emulate fxsave and fxrstor
Date: Wed, 26 Oct 2016 22:50:12 +0200 [thread overview]
Message-ID: <20161026205014.19801-1-rkrcmar@redhat.com> (raw)
[1/2] adds the emulation (and could be split into two patches if you'd like),
[2/2] just refactors the code.
This should fix an issue that users are hitting. Laszlo found several reports:
- https://bugs.launchpad.net/qemu/+bug/1623276
- https://bugzilla.proxmox.com/show_bug.cgi?id=1182
- https://bugs.archlinux.org/task/50778
I have only tested it with a simple kvm-unit-tests, though. Reproducing the
iPXE issue is on the way ...
