* x86, hvm: Fix softtsc for AMD-VKeir Fraser2008-08-153-2/+16
| | | | | | | | The softtsc code for AMD does not update the ip; enabling it on AMD-V results in the domain spinning on the RDTSC instruction. The patch is against xen-unstable 18331. Signed-off-by: John Byrne <john.l.byrne@hp.com>

* Fix restore crash with certain guest memory sizesKeir Fraser2008-08-141-7/+7
| | | | | | | | This fixes a crash when restoring guests with certain memory sizes (eg 223MB). The ROUNDUP in the call to memcpy, was the main offender, but I didn't care for the inplace resizing of the p2m entries either. Signed-off-by: Bruce Rogers <brogers@novell.com>
* x86, shadow: Fix OOS on domain crash.Keir Fraser2008-08-141-0/+10
| | | | | | | | | | | | | | | | | | I couldn't reproduce the Nevada crash on my testbox, but this should fix the first Xen crash that was seen in the Nevada HVM (bugzilla #1322). What I think most probably happened there is that the set_l2e call in shadow_get_and_create_l1e() has tried to resync a page, but somehow we weren't unable to remove the shadow (the real bug we should actually look after). sh_resync() then removes the page from the OOS hash and later in the page fault path we find the gw.l1mfn to be still OOS, so we try to update the snapshot and the bug happens. This should fix this and other unlikely (like sh_unsync() failing to remove for hash collision the current gw.l1mfn) cases. Signed-off-by: Gianluca Guida <gianluca.guida@eu.citrix.com>

| | | | | | | | | | | | | | | | | | When a p2m superpage entry is shattered, it's important not to unshadow any parts of the 2MB region that are still there afterwards. Otherwise shattering a superpage that contains the guest's top-level pagetable will cause the guest to be killed. Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com>

| * Serialize scrubbing pagesKeir Fraser2008-08-111-4/+9
| | | | | | | | | | | | | | | | | | | | | | I noticed that parallel scrubbing pages is not efficient due to spinlock contention. (also memory bandwidth?) Actually heap_lock becomes a bottleneck. In my investigation, it often takes 1 millisec just to acquire the lock on ia64 with 8cpus. It's very wasteful. Signed-off-by: Kouya Shimura <kouya@jp.fujitsu.com>

| * ia64: PV driver domains - ugly python hacksKeir Fraser2008-08-081-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86 IOMMU support added a lot of assumptions about what PCI buses look like and where to find bridge devices. On ia64, we don't yet have virtualization friendly IOMMUs, so for the moment, we just want to keep "unsafe" PV PCI pass through working as well as it did in Xen 3.2. Looking at the code, it almost seems like x86 has thrown out support for the old style driver domain. Things that don't necessarily work on every PCI compliant architecture: * You can't assume that just because there's a device at 01:01.0 that there's also a bridge at 01:00.0 and blow-up when you don't find it. On HP ia64 boxes, PCI root bridges are not necessarily exposed as a PCI device. This pretty much means we can't call into any of the "FLR" code paths. * BAR alignment: it's hard to have BAR alignment when your page size is 16k. This wasn't a requirement for previous PV driver domains, so I assume it's only for IOMMU support. This is ugly, so I'm open to suggestions. It seems that all of these architecture checks could be replaced by checking some "iommu_present" variable to test whether the extra requirements are necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On bootup, I get a couple of these: (XEN) ACPI Warning (tbutils-0219): Incorrect checksum in table [APIC] - CE, should be 04 [20070126] (XEN) ACPI Warning (tbutils-0219): Incorrect checksum in table [APIC] - CE, should be 04 [20070126] I don't remember seeing them before, but they're pretty easy to fix. The problem is we update the lsapics, causing the checksum to be wrong, then we look for platform interrupt sources, which spits out a warning, and finally we look for the MADT again to fix the checksum, which also prints a warning. If we grab a pointer to the MADT before these, we can update the checksum after each step and avoid the warnings. Signed-off-by: Alex Williamson <alex.williamson@hp.com>
