KVM is guaranteed to end up in a # broken state because the callers fully expect a valid SPTE, it's # all but dangerous to let more MMU changes happen afterwards # # x86 - AMD: # # - Make per-CPU save_area allocations NUMA-aware # # - Force sev_es_host_save_area() to be inlined to avoid calling into # an instrumentable function from noinstr code # # - Base support for running SEV-SNP guests. API-wise, this includes a # new KVM_X86_SNP_VM type, encrypting/measure the initial image into # guest memory, and finalizing it before launching it. Internally, # there are some gmem/mmu hooks needed to prepare gmem-allocated # pages before mapping them into guest private memory ranges # # This includes basic support for attestation guest requests, enough # to say that KVM supports the GHCB 2.0 specification # # There is no support yet for loading into the firmware those signing # keys to be used for attestation requests, and therefore no need yet # for the host to provide certificate data for those keys. # # To support fetching certificate data from userspace, a new KVM exit # type will be needed to handle fetching the certificate from # userspace. # # An attempt to define a new KVM_EXIT_COCO / KVM_EXIT_COCO_REQ_CERTS # exit type to handle this was introduced in v1 of this patchset, but # is still being discussed by community, so for now this patchset # only implements a stub version of SNP Extended Guest Requests that # does not provide certificate data # # x86 - Intel: # # - Remove an unnecessary EPT TLB flush when enabling hardware # # - Fix a series of bugs that cause KVM to fail to detect nested # pending posted interrupts as valid wake eents for a vCPU executing # HLT in L2 (with HLT-exiting disable by L1) # # - KVM: x86: Suppress MMIO that is triggered during task switch # emulation # # Explicitly suppress userspace emulated MMIO exits that are # triggered when emulating a task switch as KVM doesn't support # userspace MMIO during complex (multi-step) emulation # # Silently ignoring the exit request can result in the # WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace # for some other reason prior to purging mmio_needed # # See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write # exits if emulator detects exception") for more details on KVM's # limitations with respect to emulated MMIO during complex emulator # flows # # Generic: # # - Rename the AS_UNMOVABLE flag that was introduced for KVM to # AS_INACCESSIBLE, because the special casing needed by these pages # is not due to just unmovability (and in fact they are only # unmovable because the CPU cannot access them) # # - New ioctl to populate the KVM page tables in advance, which is # useful to mitigate KVM page faults during guest boot or after live # migration. The code will also be used by TDX, but (probably) not # through the ioctl # # - Enable halt poll shrinking by default, as Intel found it to be a # clear win # # - Setup empty IRQ routing when creating a VM to avoid having to # synchronize SRCU when creating a split IRQCHIP on x86 # # - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with # a flag that arch code can use for hooking both sched_in() and # sched_out() # # - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid # truncating a bogus value from userspace, e.g. to help userspace # detect bugs # # - Mark a vCPU as preempted if and only if it's scheduled out while in # the KVM_RUN loop, e.g. to avoid marking it preempted and thus # writing guest memory when retrieving guest state during live # migration blackout # # Selftests: # # - Remove dead code in the memslot modification stress test # # - Treat "branch instructions retired" as supported on all AMD Family # 17h+ CPUs # # - Print the guest pseudo-RNG seed only when it changes, to avoid # spamming the log for tests that create lots of VMs # # - Make the PMU counters test less flaky when counting LLC cache # misses by doing CLFLUSH{OPT} in every loop iteration" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (227 commits) # crypto: ccp: Add the SNP_VLEK_LOAD command # KVM: x86/pmu: Add kvm_pmu_call() to simplify static calls of kvm_pmu_ops # KVM: x86: Introduce kvm_x86_call() to simplify static calls of kvm_x86_ops # KVM: x86: Replace static_call_cond() with static_call() # KVM: SEV: Provide support for SNP_EXTENDED_GUEST_REQUEST NAE event # x86/sev: Move sev_guest.h into common SEV header # KVM: SEV: Provide support for SNP_GUEST_REQUEST NAE event # KVM: x86: Suppress MMIO that is triggered during task switch emulation # KVM: x86/mmu: Clean up make_huge_page_split_spte() definition and intro # KVM: x86/mmu: Bug the VM if KVM tries to split a !hugepage SPTE # KVM: selftests: x86: Add test for KVM_PRE_FAULT_MEMORY # KVM: x86: Implement kvm_arch_vcpu_pre_fault_memory() # KVM: x86/mmu: Make kvm_mmu_do_page_fault() return mapped level # KVM: x86/mmu: Account pf_{fixed,emulate,spurious} in callers of "do page fault" # KVM: x86/mmu: Bump pf_taken stat only in the "real" page fault handler # KVM: Add KVM_PRE_FAULT_MEMORY vcpu ioctl to pre-populate guest memory # KVM: Document KVM_PRE_FAULT_MEMORY ioctl # mm, virt: merge AS_UNMOVABLE and AS_INACCESSIBLE # perf kvm: Add kvm-stat for loongarch64 # LoongArch: KVM: Add PV steal time support in guest side # ... # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 2c9b3512402ed192d1f43f4531fb5da947e72bd0 # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64le_defconfig Using /kisskb/src/arch/powerpc/configs/ppc64_defconfig as base Merging /kisskb/src/arch/powerpc/configs/le.config # # merged configuration written to .config (needs make) # # < make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 # Build took: 0:01:56.990341
