Hi, This series is what I believe to be a fairly complete set of patches to map EFI memory into the same location that Linux does. The memory is protected by an RID so that it doesn't conflict with domain memory - which also protects it from malicious access from HVM domains.
The primary motivation for this is that EFI memory can only be mapped once - a restriction in the EFI specification. Thus for kexec betwen Xen and Linux, inluding kdump of Xen (into Linux), EFI memory needs to be mapped in the same location in both Xen and Linux. I know these patches have been in the pipeline for a long time. But they do seem to have stabilised - on my hardware at least - and I would like to move towards getting them merged. I have tested these patches on a Tiger 4 and RX 2620. I recommend testing these patches using: Xen http://xenbits.xensource.com/ext/ia64/xen-unstbale.hg Revision: 17161:71a8366fb212 Linux-Xen http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg Revision: 457:68e78169679e Kexec-Tools git://git.kernel.org/pub/scm/linux/kernel/git/horms/kexec-tools-testing.git Revision: 94afdd9f7ab2b07997f80a297741842f9cdbdc25 Linux Revision: 2.6.25-rc3 -- Horms _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel
