Add direct pci device assignment support. This patch depends on the previous patch (1/3). ----------------------------------------- Fields for DPCI class: (RO_inst) VM PPCI hotplug_slot <- same as vslot param of pci-attach/detach. (RO_run) virtual_domain virtual_bus virtual_slot virtual_func virtual_name <- domain:bus:slot:func that is seen from guest. RPCs for DPCI class:...

If a VM has all its PCI devices deassigned, need_iommu(d) becomes false but it might still have DPCI EOI timers that were init_timer()d but not yet kill_timer()d. That causes xen to crash later because the linked list of inactive timers gets corrupted, e.g.: (...

...f: use "ioapic_ack=old" for /boot/xen.gz (io_apic.c contains code for avoiding global interrupt problem) 4) description of hvm PCI device assignment design: - pci config virtualization - Control panel and qemu changed to pass assigned PCI devices to qemu. - A new file ioemu/hw/dpci.c reads assigned devices PCI conf and constructs a new virtual device and attaches to the guest PCI bus. - PCI read/write functions are similar to other virtual devices. Except write function intercepts writes to COMMAND register and do actual hardware writes. - interrupt virtualizat...
