Hi Atsushi,
Could you give my latest patch a try on IA-64? I didn't merge your

Hi, Tristan
Thank you for your comments.
I am wondering the code of arch/i386/pci/pcifront.c and irq-xen.c for x86.
(IA64 does not have it)
The [EMAIL PROTECTED]/i386/pci/irq-xen.c is pci_sal_read/write for IA64.
(DomU/VTI cannot access PCI configuration)

I'm just watching through the source code of PCI front/back driver.
But I did not understand the interface of Para/IA64 kernel.
(x86 has driver at linux-sparce/arch/x86/driver/pci
but IA64 does not have such.)
If anyone know the interface, please let me know thanks.

Hi,
My primary motivation is correct display of xenmon.py and xentop in BVT/CREDIT.
(N.B. SEDF displayed as same as x86, but BVT/CREDIT are not)
If only domU emulation is applied, it is a half way from my motivation.
Is dom0 dispatch another home work?

I have a question about Domain time update in IA64.

But in ia64, the function is null at this moment.
Is there any plan to change the function specification ?
