* blktap2: make protocol specific usage of shared sring explicitKeir Fraser2010-08-152-3/+11
| | | | | | | | | | | | | | | | | I don't think protocol specific data really belongs in this header but since it is already there and we seem to be stuck with it let's at least make the users explicit lest people get caught out by future new fields moving the pad field around. This is the Xen portion of this change. The kernel portion will be sent separately. There is no dependency between the two.

* Fix IOAPIC S3 with interrupt remapping enabledKeir Fraser2010-08-131-6/+6
| | | | | | | | | | | | | | | | | | | In ioapic_suspend, it reads and saves ioapic RTEs. But when interrupt remapping is enabled, io_apic_read will call io_apic_read_remap_rte to convert remapped format interrupt to compatible format, this results in 'dest' field may be changed in remap_entry_to_ioapic_rte. When in ioapic_resume, it will write the saved RTEs with incorrect 'dest' to interrupt remapping table. Actually it needn't to convert RTEs regardless interrupt remapping is enabled or not. It just needs to save and restore RTE values directly. This patch just uses __io_apic_read and __io_apic_write, which won't call Interrupt remapping functions to convert, to save and restore RTEs in ioapic_suspend and ioapic_resume. Thus fix this issue.

* vt-d: Fix ioapic write order in io_apic_write_remap_rteKeir Fraser2010-08-091-2/+2
| | | | | | | | | | | | | At the end of io_apic_write_remap_rte, it writes new entry (remapped interrupt) to ioapic. But it writes low 32 bits before high 32 bits, it unmasks interrupt before writing high 32 bits if 'mask' bit in low 32 bits is cleared. Thus it may result in issues. This patch fixes this issue by writing high 32 bits before low 32 bits.

* Walking the page lists needs the page_alloc lockKeir Fraser2010-08-024-1/+13
| | | | | | | | | | | | | | | | | | | There are a few places in Xen where we walk a domain's page lists without holding the page_alloc lock. They race with updates to the page lists, which are normally rare but can be quite common under PoD when the domain is close to its memory limit and the PoD reclaimer is busy. This patch protects those places by taking the page_alloc lock. I think this is OK for the two debug-key printouts - they don't run from irq context and look deadlock-free. The tboot change seems safe too unless tboot shutdown functions are called from irq context or with the page_alloc lock held. The p2m one is the scariest but there are already code paths in PoD that take the page_alloc lock with the p2m lock held so it's no worse than existing code.
