This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git

Hi Jérôme, Ben and Jason, below is a series against the hmm tree which starts revamping the migrate_vma functionality. The prime idea is to export three slightly lower level functions and thus avoid the need for migrate_vma_ops callbacks.

Hi, This is a proof of concept of GPU forwarding for Linux guest on Linux host. I'd like to get comments and suggestions from community before I put more time on it. To summarize what it is: 1. It's a solution to bring GPU acceleration for Linux vm guest on Linux host. It could works with different GPU although the current proof of concept only works with Intel GPU. 2. The basic idea

These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM self tests. Patch 7-8 prepare nouveau for the meat of this series which adds support and testing for compound page mapping of system memory (patches 9-11) and compound page migration to device private memory (patches 12-16). Since these changes are split

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it
