* Revert 20954:b4041e7bbe1b "paging_domctl: Add missing breaks in switch stmt"Keir Fraser2010-02-261-2/+0
| | | | | | | | | | | This fixed a fairly innocuous bug (OP_ENABLE/OP_OFF both don't work properly) but unmasked a much nastier one (turning off shadow mode on a PV guest crashes the hypervisor). So, for now, we pick the less of two evils. We don't really much rely on OP_ENABLE/OP_OFF anyway, as it happens. Signed-off-by: Keir Fraser <keir.fraser@citrix.com>

* vtd: interrupt remapping: be more defensiveKeir Fraser2010-02-242-0/+25
| | | | | | | | | | | | | | 1) A buggy BIOS may not report IOAPIC in DRHD. Currently we still try to enable IR while the IOAPIC RTEs are still in non-remappable format and the host would hang. The patch detects this case and will not try to enable IR. 2) Currently HPET's MSI mode doesn't work if IR is enabled because we have no code to allocate IRTE for it. Luckily this HW configuration is rather rarely at present, we can just work it around by only using HPET's IOAPIC mode for now. Signed-off-by: Dexuan Cui <dexuan.cui@intel.com>

* xend: notify xenpv device model that console info is readyKeir Fraser2010-02-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | Sometimes PV domain with vfb doesn't boot up. /sbin/kudzu is stuck. After investigation, I've found that the evtchn for console is not bound at all. Normal sequence of evtchn initialization in qemu-dm for xenpv is: 1) watch xenstore backpath (/local/domain/0/backend/console/<domid>/0) 2) read console info (/local/domain/<domid>/console/{type, ring-ref, port..= }) 3) bind the evtchn to the port. But in some case, xend writes to the backpath before the console info is prepared, and never write to the backpath again. So the qemu-dm fails at 2) and never reach to 3). When this happens, manually xenstore-write command on Domain-0 resumes the guest. Signed-off-by: Kouya Shimura <kouya@jp.fujitsu.com>
