Implement and use DOM0_DOMAIN_STEUP.
DOM0_GETMEMLIST now reads ptes and use gpfn.
Domain builder reworked: calls DOMAIN_SETUP, setup start_info page.
SAL data are now in domain memory.
is_vti field added in domain.arch.
Many cleanups (indentation, static, warnings).

[Xen-ia64-devel] [PATCH] emulate PAL_HALT_LIGHT on domU
Hi, All This patch emulates Guest PAL_HALT_LIGHT on domU by using do_block and timer. It also adds the function of the timer event sending to domU at the vcpu woke up. Signed-off-by: Atsushi SAKAI [EMAIL PROTECTED] About the timer event sending to domU The function xen_timer_interrupt on ParaVM/IA64 only sends the timer signal to current vcpu. When the idle domain is running, no domUx receives timer signal. If some domain cannot receive the timer signal during 10 secs, a message BUG: soft lockup detected appeared comes from domUx. To avoid this, I add a timer check routine at the vcpu woke up. I tested a few days.

Re: [Xen-ia64-devel] [PATCH] emulate PAL_HALT_LIGHT on domU
Hi Sakai. xenLinux/x86 paravirtualizes idle loop to get timer interrupt while cpu halting. More exactly safe_halt() is paravirtualized using HYPERVISOR_set_timer_op(). Xen/IA64 doesn't support HYPERVISOR_set_timer_op(), but it would be quite easy to add its support. I'm not sure about which is better, your approach or paravirtualizing idle loop. Could you explain the reason why you added vcpu-arch.hlt_timer instead of supporting set_timer_op hypercall with vcpu-timer? Thanks.
