Re: [Xen-devel] Failure to get memory for GATT table, again

I seem to have narroved the problem down to the function direct_remap_area_pages() which fails on an MMU update.

Xen tells me about this, in:

(XEN) (file=/mnt/hda3/home/jacobg/xeno-unstable.bk/xen/include/asm/mm.h, line=157) Error pfn 0003ff40: ed=fc599260, sd=fc5996a0, caf=80000002, taf=f0000001

You're trying to do this in dom0, right? Do you have any other domains

Yes, only dom0 is running.

If so, use the 'q' debug key to find out the domain pointers. It might
be helpful to add a show_registers after the DPRINTK so that we can see
the call trace.

I added the following:

struct xen_regs *regs = (struct xen_regs *)get_execution_context();

and the output is now:

(XEN) (file=/mnt/hda3/home/jacobg/xeno-unstable.bk/xen/include/asm/mm.h, line=157) Error pfn 0003ff40: ed=fc599260, sd=fc5996a0, caf=80000002, taf=f0000001

Hope this helps.
