From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this

Xend will do a hypercall to destory domain when creating VTI guest fail. If "is_vti" not be set at this point, HV will call relinquish_vcpu_resource() which belong to domU. It may try to free a NULL pointer, so dom0 crash. This patch fix it. Signed-off-by, Zhang Xin < xing.z.zhang@intel.com > Good good study,day day up ! ^_^ -Wing(zhang xin) OTC,Intel Corporation

Dear David Techer, I have read through your article on Xen VGA passthrough on http://www.davidgis.fr. It appears that the following command on your blog doesn''t work. dmesg | grep 01:00.0 | grep BAR The above command shows nothing at all. Is there an alternative solution? Thank you very much. Yours sincerely, Teo En Ming (Zhang Enming)

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

Upgrade clang? I can't reproduce it with trunk.

Hi all, I was trying to fit a Gamma hierarchical model using "glmer", but got weird error message that I could not understand. On the other hand, a similar call to the glmmPQL leads to results that are close to what I expect. I also tried to change tha "nAGQ" argument in "glmer", but it did not solve the problem. The model I was fitting has a simple structure - one

Does upstream dom0 support superpage? best regards yang

Hi Yongjie, I have just compiled and installed Xen 4.3-unstable changeset 26666 and Linux kernel 3.8.1, according to your specifications. However, I still cannot get success with Intel HD Graphics 4600 IGD VGA passthrough. Although in Device Manager in Windows 7 HVM domU, it says "This device is working properly" for Intel HD Graphics 4600, I can only get 16 colors. Please refer to

Hi, How come gfx_passthru is now an invalid option? Does it mean Xen-unstable 4.4 changeset 27214 no longer supports vga passthrough? -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Dear Intel Engineers, I am unable to get Intel integrated graphics (IGD) VGA passthrough to work with Xen 4.0.1-rc6-pre, Xen 4.0.1-RELEASE, pv-ops dom0 kernel 2.6.32.19 and 2.6.32.21. The moment the command "xm create <Windows XP HVM guest>" is executed, the screen immediately goes blank with the label "NO SIGNAL". It may take anywhere from 3-10 minutes before

irq: Exclude percpu IRQs from being fixed up Xen spin unlock uses spurious ipi "lock_kicker_irq" to wake up blocked vCPUs waiting on that lock. This irq should always be disabled. However, when Dom0 is shuting down, function fixup_irqs is called which unmasks all irqs. Function unmask_irq effectively re-enables lock_kicker_irq and its irq handler is invoked which reports bug and crashes
