...A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the low hanging fruits ;) Changes in v3: * Rename monitor command to ''system_wakeup''. * Fix tyops in documentation. Changes in v2: * Add a suspend notifier. * Replace the cmos_s3 qemu_irq with the notifier, zap a bunch of hackish cmos_s3 windup code (this touches xen-all.c, thus cc xen-devel). * Add rtc wakeup support. Gerd Hoffmann (6): suspend: add infrastructure suspend: switch acpi s3 to new infrastructure. suspend: add system_wakeup monitor command suspend: make...

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

I have been investigating pci pass-through for virtualized guests and the documentation I have found seems to me to lack a certain consistency in its example. This may be due to my not understanding what it is trying to inform me. What I wish to do is to configure a pci multi-port serial i/o card for use by a single virtual host. I start by running lspci -v on the host to identify the serial

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).

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

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.
