Hi all, this small patch series fixes the build breakage introduced by f1dbf015dfb0aa7f66f710a1f1bc58b662951de2 with Xen < 4.2. The problem is that xc_hvm_inject_msi is only defined from Xen 4.2 onwards so we need to provide a compatibility function for older Xen versions. Stefano Stabellini (2): xen,configure: detect Xen 4.2 xen: add a dummy xc_hvm_inject_msi for Xen < 4.2

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

But some hvm pages'' pfns are larger than 0xfffff. So, in the p2m_gfn_to_mfn, the judgement condition is valid:(p2m->max_mapped_pfn = 0xfffff) if ( gf...

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

...the interesting code (all 100 lines of it) is in hw/xen.c in the xen_init_pv method - which is called when using the ''-M xenpv'' command line arg. The first thing this does is get the domain ID - to avoid touching QEMU''s command line args, I just use an environ variable XEN_DOMID to pass this in. The main_loop() in qemu/vl.c assumes there is always one CPU created in the VM, but for our purposes we''re not doing any CPU emulation merely using the event loop/display state. So to workaround this assumption I create a single CPUState * instance, and permanently dis...

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the

Implement a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests.

Goodmorning, I''m currently playing with XEN/arm on my Allwinner A20 (cubieboard2) I would like to get the XENFB driver working on domU. But currently in xen/arm there''s no support for VFB, atleast qemu is not supported. But this video http://www.youtube.com/watch?v=po1IeElg8tg and this one http://www.youtube.com/watch?v=Km6gBnIqaWo is showing a working framebuffer. So there are
