Hi
I am maybe late on this issue but has anyone tried credit scheduler on
xen/ia64 ?
I suppose it doesn't work well because we don't support vcpu migration yet.
Tristan.

this patch add a new hypercall to set shared_info address.
Currently it is disabled in order not to break backward compatibility with
previous Xen (for FC6 people).
Tested by booting dom0+domU (2w) using old address

It is possible to build kernels (and Xen) with different page size.
Such configurations are not yet working, but as a first step this

Hi,
I updated my init handler patches.
I reflected commets.
And to make it easy to read, I devide my patch to piaces.

[4/9] add unw_init_from_interruption()

The attached patch enables interrupts for xencons on UARTs described
via the HCDP/PCDP tables. This gets a little messy because the old HCDP
doesn't provide interrupt polarity/trigger info. If the UART is on a
PCI device we can assume it's low/level, otherwise we have to resort to
more
fix GATE_ADDR for ia64_do_show_stack().
I use KERNEL_START which is Xen's text start address.

This fix is workaround. Now LOAD_PHYSCAL is used only
by MCA/INIT handler. I'll try to make dinamic patch function.
I'll remove this fix if I make it.
So please apply for supporting INIT handler.

I modified linux code to make this fix.
difference between linux and my fix
- ia64_init_stack_addr have address of ia64_mca_data[i].init_stack.
I computed address of init_stack by using it.
- from dep r12=-1,r12,61,3; to dep r12=-1,r12,60,4;
to computed xen virtual address.

This is main patch for supporting INIT handler.
I update this patch.
- into xen/arch/ia64/xen
- make smaller mca.c.
(non-ifdef code)
In ia64_mca_init(), MCA/INIT handler is registered by ia64_sal_set_vectors().
MCA handler is ia64_monarch_init_handler in mca_asm.S

I also don't agree that the Xen keytable is only for
developers. It
may be that this is an important debugging tool and therefore required
to be able to support a real customer. I'd rather see this feature on
by default so it's there for in-the-field debugging later, and so that

Memory exchange hypercall was introduced in Xen/x86.
Its purpose is to make machine-contiguous allocation more reliable
in ENOMEM situation.
Support it on Xen/IA64 and make use of it.
