FC-HBA assigned to guest domain does not work.
I assigned FC-HBA to guest domain, but it did not work.
FC-HBA seems to write its internal memory which is mapped to host
memory space via pci transaction. But there is no mapping in IOMMU''s
page table, so that page fault occurs in IOMMU.
I think that MMIO resource mapped via p2m table should be mapped via
IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Bug for Xen-3.3.0-rc2: libpci read error. No emulation.
On 32e, we create one guest, then hotplug attach one NIC to guest, guest
can not get IP address via dhcp, guest qemu log shows "libpci read
error. No emulation ".
Here is the bug entry:
One 32e, hotplug attaching VT-d NIC to guest failed.

[PATCH][RFC] Support more Capability Structures and Device Specific
...cy of each field/bit by just simply modifying the
"emu_mask" value provided in each register table.
And for only special emulation or interacting with other components
(like hypervisor), you have to implement function corresponding to the
register.

[PATCH] ioemu-remote&ioemu: fix libpci error handling.
...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.
After applying this patch, if libpci returns ALL F, ioemu will log
warning message and continue the emulation.

[PATCH] fix memory allocation from NUMA node for VT-d.
...ther hand, Address Translation Structure exists per guest domain.
So, it needs allocating the memory for Address Translation Structure
from NUMA node which guest domain runs.
This patch is useful for a system which has many IOMMUs.

[PATCH] dom0 linux: Reassign memory resources to device for pci passthrough.
...ign reassigns all devices'' memory resources if they are
not page-aligned. This is not safe, because some devices are
used by firmware.

[PATCH] Improve the current FLR logic
Hi, all,
The attached patches try to improve the current FLR logic.
The idea is: removing the FLR logic from hypervisor and adding the
improved logic in Control Panel.
The current FLR logic in hypervisor has some issues: 1) Dstate
transition is not guaranteed to properly clear the device state; 2) the
current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND
doesn''t mean the
