...Dom0 has more than 10 vcpus pinned with each physical CPU. With the patchset, the performance is 2x of the original throughput. Case 2: Dom0 has 4 vcpus pinned with 4 physical CPUs. With the patchset, the performance is 3.7x of the original throughput. when we test this patch, we found that the domain_lock in grant table operation (gnttab_copy()) becomes a bottle neck. We temporarily remove the global domain_lock to achieve good performance. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The initial values of the wallclock time in the shared info page are set for PVHVM guests when the hypercall page is initialized, since the hypercall page is not reinitialized on resume, the hypervisor wallclock time is not properly set on resume. Fix it by forcing an update of the wallclock values when the shared info page is mapped. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

Hi all, this small patch series implement guest SMP support for ARM, using the ARM PSCI interface for secondary cpu bringup. Stefano Stabellini (4): xen/arm: basic PSCI support, implement cpu_on xen/arm: support for guest SGI xen/arm: support vcpu_op hypercalls xen: move VCPUOP_register_vcpu_info to common code xen/arch/arm/domain.c | 66 ++++++++++++++++++++++++

The first patch really isn''t as much of a follow-up than what triggered the security issues to be noticed in the first place. 1: x86: preserve FPU selectors for 32-bit guest code 2: x86: fix XCR0 handling 3: x86/xsave: adjust state management 4: x86/fxsave: bring in line with recent xsave adjustments The first two I would see as candidates for 4.3 (as well as subsequent backporting,

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -
