[Xen-devel] Re: [PATCH] kexec: framework and i386 (Take XIII)

[Horms <horms@xxxxxxxxxxxx>]

Hi,

here is a minor update of the kexec/kdump patchset.
The changes since the last post are quite minimal.

* Forward port to xen-unstable-11059 from 10650
* Add powerpc stubs to 51.1-kexec-generic-upstream.patch
  going to get messy as more architectures are added

The patches are currently:

   1. 51.1-kexec-generic-upstream.patch
      * Common code for all architectures,
        the basic plumbing for kexec/kdump

   2. 51.1.1-kexec-trigger_crash_dump.patch
      * xen-console trigger crash_dump
      * Depends on 1

   3. 51.2.1-kexec-x86-upstream.patch
      * Glue between 1, and 3 and 4.
        This would not be needed for ppc or ia64, but
        neither have been written yet.
        We are planning to commence work on ia64 soon.
      * Depends on 1

   4. 51.2.1.1-kexec-x86_32-upstream.patch
      * Kexec/kdump for x86_32
      * Depends on 3 (and 1)

   5. 51.2.31.2-kexec-x86_64-upstream.patch
      * * Kexec/kdump for x86_64
      * Depends on 3 (and 1)

Things that are being worked on:

* Porting kexec for ia64. This is going somewhat slower than
  I had hoped. Partly because of my own schedule. And partly
  because the Linux code is flakier than I previously thought.

  If anyone cares, the problem that is currently bothering me
  most about linux ia64 kexec is that you can usually kexec once,
  but twice doesn't work.

  e.g. linux --kexec--> linux: ok
       linux --kexec--> linux --kexec fails--> linux: not ok

* Kdump for x86_64. My colleague Magnus is working on this.
  But he is seeing a very strange problem where kdumping
  into a bzimage works, while a vmlinux does not.
  
  Please prod him if you want more details.

Things that would be good to work on:

* PPC port
