Subject: [PATCH 0 of 7] Fix kexec in Xen (take 4)
Date: Mon, 13 Jun 2011 18:02:47 +0100 [thread overview]
Message-ID: <patchbomb.1307984567@andrewcoop.uk.xensource.com> (raw)
This set of patches are partly bugfixed to problems I have noticed while working on this area of the codebase, and targeted fixes to get the kexec path working again on Xen 4.x
The first three patches are small bugfixes which are not directly related to the kexec problems, but are on the codepath.
The next four patches are directly related to fixing the kexec path.
These patches cause xen to track the BSP local APIC boot state and return to it before kexec'ing to a new kernel. This prevents the kdump kernel falling over itself when booting in x2apic mode while expecting to be in xapic mode.
It also makes sure to disable IO virtualisation, along with fixing the current codepath related to disabling Interrup Remapping on Intel VTD boxes.
