Linus, I am sending an early pull request with the material that does not depend on any bare metal changes, especially since ARM64 and PPC submaintainers have already sent their stuff to me. The following changes since commit 87aa9ec939ec7277b730786e19c161c9194cc8ca: KVM: x86/mmu: Fix TDP MMU zap collapsible SPTEs (2021-02-04 04:38:53 -0500) 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 8c6e67bec3192f16fa624203c8131e10cc4814ba: Merge tag 'kvmarm-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2021-02-12 11:23:44 -0500) ---------------------------------------------------------------- x86: - Support for userspace to emulate Xen hypercalls - Raise the maximum number of user memslots - Scalability improvements for the new MMU. Instead of the complex "fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent, but the code that can run against page faults is limited. Right now only page faults take the lock for reading; in the future this will be extended to some cases of page table destruction. I hope to switch the default MMU around 5.12-rc3 (some testing was delayed due to Chinese New Year). - Cleanups for MAXPHYADDR checks - Use static calls for vendor-specific callbacks - On AMD, use VMLOAD/VMSAVE to save and restore host state - Stop using deprecated jump label APIs - Workaround for AMD erratum that made nested virtualization unreliable - Support for LBR emulation in the guest - Support for communicating bus lock vmexits to userspace - Add support for SEV attestation command - Miscellaneous cleanups PPC: - Support for second data watchpoint on POWER10 - Remove some complex workarounds for buggy early versions of POWER9 - Guest entry/exit fixes ARM64 - Make the nVHE EL2 object relocatable - Cleanups for concurrent translation faults hitting the same page - Support for the standard TRNG hypervisor call - A bunch of small PMU/Debug fixes - Simplification of the early init hypercall handling Non-KVM changes (with acks): - Detection of contended rwlocks (implemented only for qrwlocks, because KVM only needs it for x86) - Allow __DISABLE_EXPORTS from assembly code - Provide a saner follow_pfn replacements for modules ---------------------------------------------------------------- Regarding conflicts, I would have expected git to figure it out, but anyway the line in the pull request is the correct one: <<<<<<< pull request (correct) vcpu->arch.reserved_gpa_bits = kvm_vcpu_reserved_gpa_bits_raw(vcpu); ======= vcpu->arch.cr3_lm_rsvd_bits = rsvd_bits(cpuid_maxphyaddr(vcpu), 63); >>>>>>> 5.11 Thanks, Paolo Alexandru Elisei (1): KVM: arm64: Correct spelling of DBGDIDR register Andrew Scull (1): KVM: arm64: Simplify __kvm_hyp_init HVC detection Ard Biesheuvel (2): firmware: smccc: Add SMCCC TRNG function call IDs KVM: arm64: Implement the TRNG hypervisor call Bandan Das (1): KVM: SVM: Add emulation support for #GP triggered by SVM instructions Ben Gardon (30): KVM: selftests: Rename timespec_diff_now to timespec_elapsed KVM: selftests: Avoid flooding debug log while populating memory KVM: selftests: Convert iterations to int in dirty_log_perf_test KVM: selftests: Fix population stage in dirty_log_perf_test KVM: selftests: Add option to overlap vCPU memory access KVM: selftests: Add memslot modification stress test KVM: selftests: Add backing src parameter to dirty_log_perf_test KVM: selftests: Disable dirty logging with vCPUs running KVM: x86/mmu: change TDP MMU yield function returns to match cond_resched KVM: x86/mmu: Add comment on __tdp_mmu_set_spte KVM: x86/mmu: Add lockdep when setting a TDP MMU SPTE KVM: x86/mmu: Don't redundantly clear TDP MMU pt memory KVM: x86/mmu: Factor out handling of removed page tables KVM: x86/mmu: Fix braces in kvm_recover_nx_lpages KVM: x86/mmu: Merge flush and non-flush tdp_mmu_iter_cond_resched KVM: x86/mmu: Rename goal_gfn to next_last_level_gfn KVM: x86/mmu: Ensure forward progress when yielding in TDP MMU iter KVM: x86/mmu: Yield in TDU MMU iter even if no SPTES changed KVM: x86/mmu: Skip no-op changes in TDP MMU functions KVM: x86/mmu: Clear dirtied pages mask bit before early break KVM: x86/mmu: Protect TDP MMU page table memory with RCU locking/rwlocks: Add contention detection for rwlocks sched: Add needbreak for rwlocks sched: Add cond_resched_rwlock KVM: x86/mmu: Use an rwlock for the x86 MMU KVM: x86/mmu: Factor out functions to add/remove TDP MMU pages KVM: x86/mmu: Use atomic ops to set SPTEs in TDP MMU map KVM: x86/mmu: Flush TLBs after zap in TDP MMU PF handler KVM: x86/mmu: Mark SPTEs in disconnected pages as removed KVM: x86/mmu: Allow parallel page faults for the TDP MMU Brijesh Singh (1): KVM/SVM: add support for SEV attestation command Chenyi Qiang (4): KVM: X86: Reset the vcpu->run->flags at the beginning of vcpu_run KVM: VMX: Enable bus lock VM exit KVM: X86: Add the Document for KVM_CAP_X86_BUS_LOCK_EXIT KVM: X86: Rename DR6_INIT to DR6_ACTIVE_LOW Cun Li (1): KVM: Stop using deprecated jump label APIs David Brazdil (8): KVM: arm64: Rename .idmap.text in hyp linker script KVM: arm64: Set up .hyp.rodata ELF section KVM: arm64: Add symbol at the beginning of each hyp section KVM: arm64: Generate hyp relocation data KVM: arm64: Apply hyp relocations at runtime KVM: arm64: Fix constant-pool users in hyp KVM: arm64: Remove patching of fn pointers in hyp KVM: arm64: Remove hyp_symbol_addr David P.
