Linus, The following changes since commit 2dde18cd1d8fac735875f2e4987f11817cc0bc2c: Linux 6.5 (2023-08-27 14:49:51 -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 d011151616e73de20c139580b73fa4c7042bd861: Merge branch 'kvm-x86-mmu-6.6' into HEAD (2023-09-01 15:50:38 -0400) There are no conflict, just one remark below about a late-ish rebase of a topic branch. ---------------------------------------------------------------- ARM: * Clean up vCPU targets, always returning generic v8 as the preferred target * Trap forwarding infrastructure for nested virtualization (used for traps that are taken from an L2 guest and are needed by the L1 hypervisor) * FEAT_TLBIRANGE support to only invalidate specific ranges of addresses when collapsing a table PTE to a block PTE. This avoids that the guest refills the TLBs again for addresses that aren't covered by the table PTE. * Fix vPMU issues related to handling of PMUver. * Don't unnecessary align non-stack allocations in the EL2 VA space * Drop HCR_VIRT_EXCP_MASK, which was never used... * Don't use smp_processor_id() in kvm_arch_vcpu_load(), but the cpu parameter instead * Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort() * Remove prototypes without implementations RISC-V: * Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest * Added ONE_REG interface for SATP mode * Added ONE_REG interface to enable/disable multiple ISA extensions * Improved error codes returned by ONE_REG interfaces * Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V * Added get-reg-list selftest for KVM RISC-V s390: * PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch) Allows a PV guest to use crypto cards. Card access is governed by the firmware and once a crypto queue is "bound" to a PV VM every other entity (PV or not) looses access until it is not bound anymore. Enablement is done via flags when creating the PV VM. * Guest debug fixes (Ilya) x86: * Clean up KVM's handling of Intel architectural events * Intel bugfixes * Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug registers and generate/handle #DBs * Clean up LBR virtualization code * Fix a bug where KVM fails to set the target pCPU during an IRTE update * Fix fatal bugs in SEV-ES intrahost migration * Fix a bug where the recent (architecturally correct) change to reinject #BP and skip INT3 broke SEV guests (can't decode INT3 to skip it) * Retry APIC map recalculation if a vCPU is added/enabled * Overhaul emergency reboot code to bring SVM up to par with VMX, tie the "emergency disabling" behavior to KVM actually being loaded, and move all of the logic within KVM * Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC ratio MSR cannot diverge from the default when TSC scaling is disabled up related code * Add a framework to allow "caching" feature flags so that KVM can check if the guest can use a feature without needing to search guest CPUID * Rip out the ancient MMU_DEBUG crud and replace the useful bits with CONFIG_KVM_PROVE_MMU * Fix KVM's handling of !visible guest roots to avoid premature triple fault injection * Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface that is needed by external users (currently only KVMGT), and fix a variety of issues in the process This last item had a silly one-character bug in the topic branch that was sent to me. Because it caused pretty bad selftest failures in some configurations, I decided to squash in the fix. So, while the exact commit ids haven't been in linux-next before the merge window, the code has. Generic: * Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass action specific data without needing to constantly update the main handlers. * Drop unused function declarations Selftests: * Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs * Add support for printf() in guest code and covert all guest asserts to use printf-based reporting * Clean up the PMU event filter test and add new testcases * Include x86 selftests in the KVM x86 MAINTAINERS entry ---------------------------------------------------------------- Aaron Lewis (5): KVM: selftests: Add
