similar to: [PATCH] Fix hvm vcpu hotplug bug

Please see the three patches that fix the ACPI AML and QEMU race. They have been Ack-ed by both George (for inclusion in Xen 4.3) and by Stefano. They should be candidates for back-port in older hypervisors. Konrad Rzeszutek Wilk (3): piix4acpi, xen, vcpu hotplug: Split the notification from the changes. piix4acpi, xen: Clarify that the qemu_set_irq calls just do an IRQ pulse.

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

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

Has there been any work done on getting an ACPI fixed event or perhaps a general purpose event delivered to an HVM guest. Whereby, the HVM guests OSPM could consume the event and act accordingly. Or Perhaps better stated how would one go about passing an ACPI fixed event or general purpose event that was raised and consumed by dom0 and subsequently pass the event on to each of the HVM

Enable cpufreq support in Xen for AMD Operton processors by: 1) Allowing the PowerNow! driver in dom0 to write to the PowerNow! MSRs. 2) Adding the cpufreq notifier chain to time-xen.c in dom0. On a frequency change, a platform hypercall is performed to scale the frequency multiplier in the hypervisor. 3) Adding a platform hypercall to the hypervisor the scale the frequency multiplier and reset

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

Everyone, It looks like pdfmerge is broken after the recent upgrade of gs to ghostscript-8.70-6.el5_7.6.x86_64. Has anyone else had this problem. I have just started trying to debug it. If any of you already have solutions please let me know. Thanks, Greg Ennis

Hi, I tried to attach passrough io device to domU, the command (ended successfully in dom0), but when I entered the domU and typed the "lspci" command I didn''t see the new device, although the dom0 removed it from the "pci-list-assignable-devices". When I tried to detach it from the domU, the detach command returned with timeout error. What did I miss? perhaps I

[resending, cutting out git pull-request output to make message smaller] Hi all, I have written a COM32 module called "acpioff", that, not surprisingly, powers off a machine using ACPI. I have tested it only using pxelinux.0 with a SeaBIOS/Qemu virtual machine. Since the changeset pulls in a "Linux-ized" version of the open source ACPI Component Architecture, it was too big

tools/firmware: remove "_PS0/3" Method Do not expose the ACPI power management "_PS0/3" Method to guest firmware. According to section 3.4 of the APCI specification 4.0, PCI device control the device power through its own specification but not through APCI. Qemu pushes "_PS0/3" to guest will cause a mess between ACPI PM and PCI PM as a result of incorrect ACPI table

Hi, This is updated xen vMCE design foils, according to comments from community recently. This foils focus on vMCE part of Xen MCA, so as Keir said, it''s some dense.

Intel recently release a new tsc adjust feature at latest SDM 17.13.3. CPUID.7.0.EBX[1]=1 indicates TSC_ADJUST MSR 0x3b is supported. Basically it is used to simplify TSC synchronization, operation of IA32_TSC_ADJUST MSR is as follows: 1). On RESET, the value of the IA32_TSC_ADJUST MSR is 0; 2). If an execution of WRMSR to the IA32_TIME_STAMP_COUNTER MSR adds (or subtracts) value X from the
