Subject: [PATCH 0/8] kexec: extended kexec hypercall for use with pv-ops kernels
Date: Thu, 21 Feb 2013 17:48:06 +0000	[thread overview]
Message-ID: <1361468894-18655-1-git-send-email-david.vrabel@citrix.com> (raw)

The series improves the kexec hypercall by making Xen responsible for
loading and relocating the image.  This allows kexec to be usable by
pv-ops kernels and should allow kexec to be usable from a HVM or PVH
privileged domain.

The first patch is a simple clean-up.

The second patch allows hypercall structures to be ABI compatible
between 32- and 64-bit guests (by reusing stuff present for domctls
and sysctls).  This seems better than having to keep adding compat
handling for new hypercalls etc.

Patch 3 introduces the new ABI.

Patch 4 and 5 nearly completely reimplement the kexec load, unload and
exec sub-ops.  The old load_v1 sub-op is then implemented on top of
the new code.

Patch 6 calls the kexec image when dom0 crashes.  This avoids having
to alter dom0 kernels to do a exec sub-op call on crash -- an existing
SHUTDOWN_crash.

Patches 7 and 8 add the libxc API for the kexec calls.

The required patch series for kexec-tools will be posted shortly.

David
