* xend: Better support for legacy HVM config of ia64Keir Fraser2008-08-111-1/+1
| | | | | | | | | | | On ia64, direct Linux boot is not supported, and 'Flash.fd' or 'guest_firmware.bin' has been used as a value of the 'kernel' option. Cset:17016 ignores those strings and overrides them with "/usr/lib/xen/boot/hvmloader".

* 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.

* | [IA64] Cleanup ACPI checksum warningsIsaku Yamahata2008-08-081-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | [IA64] Fix PV driver domains - xen stubsIsaku Yamahata2008-08-082-0/+14
| | | | | | | | | | | | | | | | | | | | Stub out new hypercalls in the hypervisor. The only odd one here is map/unmap_pirq. This seems to be for MSI support, which I don't believe we currently support for driver domains, so this is actually similar to the x86 code path. The tools code doesn't allow us to return -ENOSYS here :( Signed-off-by: Alex Williamson <alex.williamson@hp.com>
