| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | paravirtualized and fully virtualized. This approach uses the new sched_op to handle other domains than the current domain. The new code, SCHEDOP_remote_shutdown, is very much like SCHEDOP_shutdown, but is called with the id of the domain which is to be shut down. This allows fully virtualized shutdown and para-virtualized shutdown to be identical from that point forward. A paravirtualized domain uses sched_op to shut down and set the reason code. This will send a VIRQ_DOM_EXC, which can be handled in dom0 by control software. In some ways, this resembles SIGCHILD/waitpid, and is a reasonable model. The fully virtualized case has qemu invoke xm directly. This is a different path than paravirtualized. It also removes decision and policy making choices from the rest of the control software and places it within qemu. When any dom0 logic eventually gets a VIRQ_DOM_EXC, the information about the domain is gone having been destroyed by xm. A libxenctrl wrapper, xc_shutdown_domain has been added and qemu now calls it. As a freebie, #if 0 some very verbose logging code in qemu. Totally unrelated, but as long as I was there...

* | [IA64] get_pfn_list workaroundawilliam@xenbuild.aw2006-04-101-20/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we know, the mechanism for hypervisor to pass parameter through pointer is not complete. Hypervisor use copy_from/to_user functions to copy parameter to hypervisor and copy result to user, if there is a tlb miss happening and hypervisor can't handled this. This hypercall fails, there is no mechanism to handle this failure, that may cause domain crash. Get_pfn_list hypercall copy large data from hypervisor to user, it is easy to trigger this issue when creating VTI-domain. If fails, Get_pfn_list returns the number of pfn entries, and this patch will Dummy access parameter memory block to cause this tlb mapping tracked by Hypervisor, then continue to do get_pfn_list. It's a workaround before we design a new mechanism of passing parameter thr pointer. Signed-off-by: Anthony Xu <anthony.xu@intel.com>

|/ | | | | | | | | | | | | | | | | | | | This patch removes ugly hack upon memory operation and thus allow inc/decrease_reservation op available for xen/ia64 now. As a result: * Now we conform to common sequence where all domain pages are allocated together by increase_reservation before image builder * physmap table is now built at point of arch_set_info_guest * DOM0_GETMEMLIST can only query without allocation now After this patch, some long-existing hacks due to mismatched memory interface are cleaned this time. Also this is a base step toward introducing balloon feature into xen/ia64. Signed-off-by Kevin Tian <kevin.tian@intel.com>

This is done by adding a parallel xc_domain_dumpcore_via_callback, which allows the specification of a callback routine and an opaque argument block.

If non-zero then a corefile is being debuged. Otherwise a thread has been attached to. This allows xc_waitdomain_core() or xc_waitdomain() to be called as appropriate in subsequent xc_ptrace() calls. * xc_waitdomain - Rename xc_waitdomain (xc_ptrace.c version) __xc_waitdomain - Rename xc_waitdomain (xc_ptrace_core.c version) xc_waitdomain_core - Create xc_waitdomain (in xc_ptrace.c), a wrapper for __xc_waitdomain and xc_waitdomain_core. Consolidation seemed difficult but ctxt needs to be passed into xc_waitdomain_core or made global. Alternatively, xc_waitdomain_core could be moved into xc_ptrace.c, but this seems messy. * map_domain_va - Rename map_domain_va (xc_ptrace_core.c version) map_domain_va_core - Have it accept ctxt, like xc_waitdomain_core * myptrace and myxcwait (linux-xen-low.c) Removed, call the now generic xc_ptrace() and xc_waitdomain() instead When calling xc_ptrace ATTACH, if a corefile is in use, a fd will be passed, otherwise a pid. The fd part is important, as this is saved internally in xc_ptrace_core.c, and passed to xc_waitdomain_core() as neccessary. Pereviously xc_waitdomain_core() received a pid and thus could not open the corefile. Signed-Off-By: Horms <horms@verge.net.au>
