[Xen-ia64-devel] Re: PATCH: all registers in vcpu_guest_context

[Alex Williamson <alex.williamson@xxxxxx>]

Hi Tristan,

   Looks like this patch is causing some problems:

http://xenbits.xensource.com/ext/xen-ia64-unstable.hg?rev/7c176473786b

Most of my machines work with it, but one fails to boot dom0.  That box
gets a NaT consumption fault with an IIP well above xen text space.  If
I chop the rbs array off the end of the vcpu_guest_context_regs it boots
fine.  This gets the structure down to a little over 5k.  I see several
places where this structure is allocated on the stack.  Are we blowing
up the stack with a 21k+ structure?  Suggestions for a fix?  Thanks,

        Alex
