* libxl, minios: stubdom console based save/restoreStefano Stabellini2011-01-216-17/+104
| | | | | | | | | | | | | | | | Add two "special" PV consoles to stubdoms that are going to be used to send and receive the qemu-xen save files on save/restore. Use the second PV console to send the qemu-xen save file and the third PV console to receive the qemu-xen save file on restore. Fix the console shutdown function free_consfront that is called when the qemu save file is closed. Stubdom save/restore is still broken with xend.

| | | | | | | | | | | | | | | | | | x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.

* | p2m: Allow non-leaf entries to be replaced by leaf entriesGeorge Dunlap2011-01-214-16/+80
|/ | | | | | | | | | | | | | | | | | | Allow l2 and l3 p2m tables to be replaced with 2MB and 1GB pages respectively, freeing the p2m table page properly. This allows, for example, a sequence of 512 singleton zero pages to be replaced with a superpage populate-on-demand entry. Changes: * Add a p2m_free_ptp() corresponding to p2m_alloc_ptp(), which will handle everything related to the freeing properly. * Add p2m_free_entry(), based on ept_free_entry(), which will free intermediate tables recursively. * For both ept and p2m, when replacing non-leaf entries with leaf entries, keep old entry and call *_free_entry() after new entry has been written and proper flushes have been done.

* libxl: Make domain_shutdown fail if graceful not possibleIan Jackson2011-01-201-17/+9
| | | | | | | | | | | | | | | | | | | | Currently "xl shutdown" (like "xm shutdown") is not capable of doing the proper ACPI negotiation with an HVM no-pv-drivers guest which would be necessary for a graceful shutdown. Instead (following the ill-advised lead of "xm shutdown") it simply shoots the guest in the head. This patch changes the behaviour so that "xl shutdown" fails if the domain cannot be shut down gracefully for this reason and suggests in the error message using destroy instead. Also, check whether the PV shutdown protocol is available before we try to use it.

* libxl: do not attempt to write "shutdown" dm-commandIan Jackson2011-01-201-5/+0
| | | | | | | | | | | | | | | | | | | | | | libxl_domain_destroy writes the command "shutdown" to the xenstore node with which it communicates with qemu. However: - qemu does not understand this command and ignores it (printing a message) - libxl doesn't wait for the answer and immediately pauses the domain anyway - destroy is the ungraceful (force) operation and should not negotiate with qemu anyway - even in the graceful shutdown case, there would actually be nothing that qemu needs to do. Under some circumstances, this entry in xenstore will survive the domain's death, ie be leaked. So remove the erroneous code.

* PoD,hap: Fix logdirty mode when using hardware assisted pagingGeorge Dunlap2011-01-171-7/+18
| | | | | | | | | | | | | When writing a writable p2m entry for a pfn, we need to mark the pfn dirty to avoid corruption when doing live migration. Marking the page dirty exposes another issue, where there are excessive sweeps for zero pages if there's a mismatch between PoD entries and cache entries. Only sweep for zero pages if we actually need more memory. Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com> Acked-by: Tim Deegan <Tim.Deegan@citrix.com>

| | | | | | | | | | | | | | | | | Userspace tools support external block scripts (e.g. block-drbd provided by drbd project). The psuedo-bootloader setup code in xend has a few limitations wrt external block scripts, which this patch addresses. blkif.py: parse_uname() utility function should be able to parse a disk specifier understood by the rest of the tools.

* xen-unstable/blkif: Add trim operation interfaceKeir Fraser2011-01-181-0/+34
| | | | | | | | | | | | | | | | Trim operation is a request for the underlying block device to mark extents to be erased. Add the operation code and ring data structure to the public header file. Trim operations are passed with sector_number as the sector index to begin trim operations at and nr_sectors as the number of sectors to be trimmed. The specified sectors should be trimmed if the underlying block device supports trim operations, or a BLKIF_RSP_EOPNOTSUPP should be returned.

| * rcupdate: Make rcu_barrier() more paranoia-proofKeir Fraser2011-01-141-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm not sure my original barrier function is correct. It may allow a CPU to exit the barrier loop, with no local work to do, while RCU work is pending on other CPUs and needing one or more quiescent periods to flush the work through. Although rcu_pending() may handle this, it is easiest to follow Linux's example and simply call_rcu() a callback function on every CPU. When the callback has executed on every CPU, we know that all previously-queued RCU work is completed, and we can exit the barrier. Signed-off-by: Keir Fraser <keir@xen.org>
