use of struct hvm_mirq_dpci_mapping.gmsi vs. HVM_IRQ_DPCI_*_MSI flags
pt_irq_create_bind_vtd() initializes this substructure only when setting
.flags to HVM_IRQ_DPCI_MACH_MSI|HVM_IRQ_DPCI_GUEST_MSI (the
PT_IRQ_TYPE_MSI case), while the other path will not set
HVM_IRQ_DPCI_GUEST_MSI but may also set HVM_IRQ_DPCI_MACH_MSI.
Yet hvm_dpci_msi_eoi() and hvm_migrate_pirqs() check for
HVM_IRQ_DPCI_MACH_MSI, i.e. may run into an uninitialized
.gmsi.* field. What am I missing her...

libmsi.a import library from wine, and header files available (entirely free software), available for python-win32 builds under msys+wine
as part of building python2.5.2 under msys under wine on linux using
mingw, i thought i'd try building _msi.pyd just for kicks. of course,
that required having an msi.lib import library, and associated header
files. so, purely as an experiment, i've documented the process by
which it is possible to take wine 1.1.13 (current development release)
source code, modify the header files for use with ming...

PCI MSI questions
...q may collide
with the dynamic IRQs in the kernel or even be out of range altogether.
Therefore I think that NR_PIRQS has to become a variable defaulting
to 256 but getting initialized from a hypervisor reported value (perhaps
in start_info, or else from a new (sub-)hypercall).
2) While pci_restore_msi_state() properly checks the success of
msi_map_pirq_to_vector(), pci_restore_msix_state() doesn''t. Is this
for a reason, or just because the code would get more complex if the
error needs to be handled?
3) The type parameter of xc_physdev_map_pirq{,_msi}() seems
superfluous, or is there a...
