[PATCH v3 13/15] KVM: Handle page fault for private memory

When a page fault from the secondary page table while the guest is running happens in a memslot with KVM_MEM_PRIVATE, we need go different paths for private access and shared access. - For private access, KVM checks if the page is already allocated in the memory backend, if yes KVM establish

[PATCH v3 03/15] mm/memfd: Introduce MEMFD_OPS

From: "Kirill A. Shutemov" The patch introduces new MEMFD_OPS facility around file created by memfd_create() to allow a third kernel component to make use of memory bookmarked in a memfd and gets notifier when the memory in the file is allocated/invalidated. It will be used for KVM to use memfd f

[PATCH v3 06/15] KVM: Refactor hva based memory invalidation code

The purpose of this patch is for fd-based memslot to reuse the same mmu_notifier based guest memory invalidation code for private pages. No functional changes except renaming 'hva' to more neutral 'useraddr' so that it can also cover 'offset' in a fd that private pages live in. Signed-off-by: Yu

[PATCH v3 00/15] KVM: mm: fd-based approach for supporting KVM guest private memory

This is the third version of this series which try to implement the fd-based KVM guest private memory. In general this patch series introduce fd-based memslot which provide guest memory through a memfd file descriptor fd[offset,size] instead of hva/size. The fd then can be created from a supported

[PATCH v3 10/15] KVM: Add kvm_map_gfn_range

This new function establishes the mapping in KVM page tables for a given gfn range. It can be used in the memory fallocate callback for memfd based memory to establish the mapping for KVM secondary MMU when the pages are allocated in the memory backend. Signed-off-by: Yu Zhang Signed-off-by: Chao

[PATCH v3 05/15] KVM: Implement fd-based memory using MEMFD_OPS interfaces

This patch adds the new memfd facility in KVM using MEMFD_OPS to provide guest memory from a file descriptor created in user space with memfd_create() instead of traditional userspace hva. It mainly provides two kind of functions: - Pair/unpair a fd-based memslot to a memory backend that owns the

[PATCH v3 07/15] KVM: Special handling for fd-based memory invalidation

For fd-based guest memory, the memory backend (e.g. the fd provider) should notify KVM to unmap/invalidate the privated memory from KVM second MMU when userspace punches hole on the fd (e.g. when userspace converts private memory to shared memory). To support fd-based memory invalidation, existing

[PATCH v3 08/15] KVM: Split out common memory invalidation code

When fd-based memory is enabled, there will be two types of memory invalidation: - memory invalidation from native MMU through mmu_notifier callback for hva-based memory, and, - memory invalidation from memfd through memfd_notifier callback for fd-based memory. Some code can be shared

[PATCH v3 15/15] KVM: Register/unregister private memory slot to memfd

[PATCH v3 09/15] KVM: Implement fd-based memory invalidation

KVM gets notified when userspace punches a hole in a fd which is used for guest memory. KVM should invalidate the mapping in the second MMU page tables. This is the same logic as MMU notifier invalidation except the fd related information is carried around to indicate the memory range. KVM hence ca

[PATCH v3 12/15] KVM: Add KVM_EXIT_MEMORY_ERROR exit

This new exit allows user space to handle memory-related errors. Currently it supports two types (KVM_EXIT_MEM_MAP_SHARED/PRIVATE) of errors which are used for shared memory <-> private memory conversion in memory encryption usage. After private memory is enabled, there are two places in KVM that

[PATCH v3 11/15] KVM: Implement fd-based memory fallocation
