* PyGRUB: fix menu flickerKeir Fraser2008-08-271-15/+17
| | | | | | | | To avoid flickers, PyGRUB has to avoid spurious ncurses refresh as much as possible, in particular before the complete screen is drawn, and eventually call doupdate last. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* vtd: do FLR before xc.domain_destroy()Keir Fraser2008-08-265-31/+67
| | | | | | | | | | | | | | When we "xm destroy" a guest with assigned devices, in xen/common/domain.c:domain_kill(), we relinquish guest's memory first, then invoke domain_destroy() -> complete_domain_destroy() -> arch_domain_destroy() -> pci_release_devices()/iommu_domain_destroy(). Between relinquish_memory() and domain_destroy(), a device may be issuing DMA request and access guest's relinquished memory. We can do_FLR() to quiesce devices before xc.domain_destroy().

* vtd: Don't do FLR when we create domain or hotplug device into guest.Keir Fraser2008-08-191-2/+6
| | | | | | | | | | | | | | | | VT-d hot-plug is done in such a way: 1) xend sends 'pci-ins' command to ioemu via xenstore; 2) ioemu creates pass-through device and raises SCI to guest OS; guest OS loads device driver, and device driver initializes the hot-plugged device; 3) xend does FLR. There is a race condition about 2) and 3). If 3) runs slow, we have troubles. Thanks for Yuji Shimada's locating the issues. We can work around the issues by not doing FLR when we create domain or hotplug device into guest, namely, we only do FLR when we destroy domain or hotplug device from guest.

| | | | | | | | 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>

* 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.

* ioemu, passthrough: fix flag for expansion rom base address register.Keir Fraser2008-08-011-0/+7
| | | | | | | | | | | | | | | pt_bar_reg_parse() is called for expansion rom base address register. Currently it returns PT_BAR_FLAG_MEM if bit 0 is 0. It returns PT_BAR_FLAG_IO if bit 0 is 1. But bit 0 in expansion rom base address register is enable bit. If bit 0 is 1 for some reason, it returns PT_BAR_FLAG_IO. Expansion rom is mapped to memory space. It should return PT_BAR_FLAG_MEM. After applying this patch, it returns PT_BAR_FLAG_MEM regardless of bit 0, when it is called for expansion rom base address register. Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp>

* ioemu: fix libpci error handling.Keir Fraser2008-08-011-6/+4
| | | | | | | | | | | libpci returns ALL F when error occurs. Currently, if libpci returns ALL F, emulation stops. But it is possible that the field of real register which is read by guest software is ALL F.

* ioemu, passthrough: fix writing handlers for base address registers.Keir Fraser2008-08-011-80/+99
| | | | | | | | | | | | | | | | This patch fixes writing handlers for base address registers (include expansion rom base address register) as follows. It can be applied to both ioemu-remote and ioemu. - Current implementation can not work fine when base address registers are accessed via 1 byte write access and 2 byte write access. This patch enables them. - Currently guest software can set address which is not aligned with resource size and page size. The patch does not allow guest software to set unaligned address.
