Subject:[Xen-devel] Re: [patch 0/3] xen: Extend xen kexec hypercall to return additional regions

Hi Simon,

I'm not seeing how this doesn't break the x86 COMPAT/CONFIG_COMPAT code paths. Where does kexec_get_range_internal() get defined for COMPAT in [1/3], and where is machine_kexec_get_xen() defined for CONFIG_COMPAT in [2/3]? I'm fine with the ia64 parts if Ian/Keir want to check them into the main tree, but there is some mixed indenting in [3/3]. Thanks,

Alex

Hi,

this series starts off by reworking the hypercall a bit to allow it to have architecture-specific code under xen/arch/

It then extends the hypercall for some extra regions that are needed for xen ia64.

There are generic and ia64 specific patches in this series. I wanted to post them together as they don't make much sense without each other.

There are related xen-linux patches that I will send as a separate series. There are related kexec-tools patches which I have posted to the kexec mailing list and intend to merge. http://lists.infradead.org/pipermail/kexec/2008-February/001348.html

The end-game here is to make sure that all the reserved regions show up in /proc/iomem_machine on ia64. This currently does not happen. And manifests as kexec only being able to be performed once as the boot parameter ends up being overwritten in relocate_kernel before purgatory is reached.

Xen--kexec-->Xen--kexec [hang in purgatory!]

The EFI-RID patches for ia64 xen kexec are also needed for kexec to function on ia64. However they touch different code paths and can be merged separately.
