Linus, The following changes since commit 8400291e289ee6b2bf9779ff1c83a291501f017b: Linux 6.11-rc1 (2024-07-28 14:19:55 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 1773014a975919195be71646fc2c2cad1570fce4: Merge branch 'kvm-fixes' into HEAD (2024-08-02 12:33:43 -0400) The bulk of the changes here is a largish change to guest_memfd, delaying the clearing and encryption of guest-private pages until they are actually added to guest page tables. This started as "let's make it impossible to misuse the API" for SEV-SNP; but then it ballooned a bit. The new logic is generally simpler and more ready for hugepage support in guest_memfd. Thanks, Paolo ---------------------------------------------------------------- * fix latent bug in how usage of large pages is determined for confidential VMs * fix "underline too short" in docs * eliminate log spam from limited APIC timer periods * disallow pre-faulting of memory before SEV-SNP VMs are initialized * delay clearing and encrypting private memory until it is added to guest page tables * this change also enables another small cleanup: the checks in SNP_LAUNCH_UPDATE that limit it to non-populated, private pages can now be moved in the common kvm_gmem_populate() function * fix compilation error that the RISC-V merge introduced in selftests ---------------------------------------------------------------- Ackerley Tng (1): KVM: x86/mmu: fix determination of max NPT mapping level for private pages Chang Yu (1): KVM: Documentation: Fix title underline too short warning Jim Mattson (1): KVM: x86: Eliminate log spam from limited APIC timer periods Paolo Bonzini (16): KVM: x86: disallow pre-fault for SNP VMs before initialization KVM: guest_memfd: return folio from __kvm_gmem_get_pfn() KVM: guest_memfd: delay folio_mark_uptodate() until after successful preparation KVM: guest_memfd: do not go through struct page KVM: rename CONFIG_HAVE_KVM_GMEM_* to CONFIG_HAVE_KVM_ARCH_GMEM_* KVM: guest_memfd: return locked folio from __kvm_gmem_get_pfn KVM: guest_memfd: delay kvm_gmem_prepare_folio() until the memory is passed to the guest KVM: guest_memfd: make kvm_gmem_prepare_folio() operate on a single struct kvm KVM: remove kvm_arch_gmem_prepare_needed() KVM: guest_memfd: move check for already-populated page to common code KVM: cleanup and add shortcuts to kvm_range_has_memory_attributes() KVM: extend kvm_range_has_memory_attributes() to check subset of attributes KVM: guest_memfd: let kvm_gmem_populate() operate only on private gfns KVM: guest_memfd: abstract how prepared folios are recorded Merge tag 'kvm-riscv-fixes-6.11-1' of https://github.com/kvm-riscv/linux into HEAD Merge branch 'kvm-fixes' into HEAD Yong-Xuan Wang (1): KVM: riscv: selftests: Fix compile error Documentation/virt/kvm/api.rst | 8 +- arch/x86/include/asm/kvm_host.h | 1 + arch/x86/kvm/Kconfig | 4 +- arch/x86/kvm/lapic.c | 2 +- arch/x86/kvm/mmu/mmu.c | 7 +- arch/x86/kvm/svm/sev.c | 17 +- arch/x86/kvm/svm/svm.c | 1 + arch/x86/kvm/x86.c | 12 +- include/linux/kvm_host.h | 9 +- tools/testing/selftests/kvm/riscv/get-reg-list.c | 8 +- virt/kvm/Kconfig | 4 +- virt/kvm/guest_memfd.c | 227 ++++++++++++++--------- virt/kvm/kvm_main.c | 73 ++++---- 13 files changed, 214 insertions(+), 159 deletions(-)
