Hi all, this patch series by Wei Liu implements a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests. The second version of this series includes the "or later" copyright clause for xen_apic.c and a fix to the return value of xen_apic_mem_read (thanks Peter for finding it out). Stefano Stabellini (2): Xen: basic HVM MSI injection support. Xen: Add

Hi, I saw that Xen support a translation between device/intx to GSI for a single PCI bus, I thought about adding multiple PCI bus support but disregard the bus information so the same device/intx on different buses will be OR wired to the same GSI, sounds reasonable? What other things do I need to support in Xen in order to add multiple PCI buses, assuming that secondary buses holds only

The OpRegion shouldn''t be mapped 1:1 because the address in the host can''t be used in the guest directly. This patch traps read and write access to the opregion of the Intel GPU config space (offset 0xfc). To work correctly this patch needs a change in hvmloader. HVMloader will allocate 2 pages for the OpRegion and write this address on the config space of the Intel GPU. Qemu

Userspace patches for the pci-passthrough functionality. The major updates since the last post are: - Loop to add passthrough devices in pc_init1 - Handle errors in read/write calls - Allow invocation without irq number for in-kernel irqchip Other than this, several small things were fixed according to review comments received last time.

Hi all, I have few simple fixes for Xen for the next release: - the first one fixes a regression in qemu-char; - the second one is just a cleanup (that is needed to simplify preprocessor dependencies); - the last one avoids setting nonblocking on Xen (as is already done for KVM). The last two patches should be backported to older branches. Stefano Stabellini (3):

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

When running on PowerPC, we don''t have native PIO support. There are a few hacks around to enable PIO access on PowerPC nevertheless. The most typical one is the isa-mmio device. It takes MMIO requests and converts them to PIO requests on the (QEMU internal) PIO bus. This however is not how real hardware works and it limits us in the ability to spawn eventfd''s on PIO ports
