[PATCH v5 10/12] KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN and event channel delivery

From: David Woodhouse This adds basic support for delivering 2 level event channels to a guest. Initially, it only supports delivery via the IRQ routing table, triggered by an eventfd. In order to do so, it has a kvm_xen_set_evtchn_fast() function which will use the pre-mapped shared_info page i

[PATCH v5 12/12] KVM: x86: First attempt at converting nested virtual APIC page to gpc

From: David Woodhouse This is what evolved during the discussion at https://lore.kernel.org/kvm/960e233f-ec0b-4fb5-ba2e-c8d2ccb38...@infradead.org/T/#m11d75fcfe2da357ec1dabba0d0e3abb91fd13665 As discussed, an alternative approach might be to augment kvm_arch_memslots_updated() to raise KVM_REQ_G

[PATCH v5 06/12] KVM: powerpc: Use Makefile.kvm for common files

From: David Woodhouse It's all fairly baroque but in the end, I don't think there's any reason for $(KVM)/irqchip.o to have been handled differently, as they all end up in $(kvm-y) in the end anyway, regardless of whether they get there via $(common-objs-y) and the CPU-specific object lists. Sig

[PATCH v5 02/12] KVM: Add Makefile.kvm for common files, use it for x86

From: David Woodhouse Splitting kvm_main.c out into smaller and better-organized files is slightly non-trivial when it involves editing a bunch of per-arch KVM makefiles. Provide virt/kvm/Makefile.kvm for them to include. Signed-off-by: David Woodhouse Acked-by: Marc Zyngier --- arch/x86/kvm/

[PATCH v5 00/12] KVM: x86/xen: Add in-kernel Xen event channel delivery

Introduce the basic concept of 2 level event channels for kernel delivery, which is just a simple matter of a few test_and_set_bit calls on a mapped shared info page. This can be used for routing MSI of passthrough devices to PIRQ event channels in a Xen guest, and we can build on it for deliverin

[PATCH v5 11/12] KVM: x86: Fix wall clock writes in Xen shared_info not to mark page dirty

From: David Woodhouse When dirty ring logging is enabled, any dirty logging without an active vCPU context will cause a kernel oops. But we've already declared that the shared_info page doesn't get dirty tracking anyway, since it would be kind of insane to mark it dirty every time we deliver an e

[PATCH v5 09/12] KVM: x86/xen: Maintain valid mapping of Xen shared_info page

From: David Woodhouse Use the newly reinstated gfn_to_pfn_cache to maintain a kernel mapping of the Xen shared_info page so that it can be accessed in atomic context. Note that we do not participate in dirty tracking for the shared info page and we do not explicitly mark it dirty every single ti

[PATCH v5 01/12] KVM: Introduce CONFIG_HAVE_KVM_DIRTY_RING

From: David Woodhouse I'd like to make the build include dirty_ring.c based on whether the arch wants it or not. That's a whole lot simpler if there's a config symbol instead of doing it implicitly on KVM_DIRTY_LOG_PAGE_OFFSET being set to something non-zero. Signed-off-by: David Woodhouse ---

[PATCH v5 08/12] KVM: Reinstate gfn_to_pfn_cache with invalidation support

From: David Woodhouse This can be used in two modes. There is an atomic mode where the cached mapping is accessed while holding the rwlock, and a mode where the physical address is used by a vCPU in guest mode. For the latter case, an invalidation will wake the vCPU with the new KVM_REQ_GPC_INVA
