Thank you!
Linus, The following changes since commit acb3f4bc2108dca531f81233383e21f0bdc02267: arm64/sysreg: Remove duplicate definitions from asm/sysreg.h (2022-12-01 17:31:12 +0000) 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 549a715b98a13c6d05452be3ad37e980087bb081: KVM: x86: Add proper ReST tables for userspace MSR exits/flags (2022-12-14 13:28:31 -0500) There are a few non-KVM changes here: - introduce FOLL_INTERRUPTIBLE, reviewed by the mm/ people; however, FOLL_PCI_P2PDMA has been introduced in the meanwhile so FOLL_INTERRUPTIBLE has to be bumped to 0x200000 on merge. - tools/perf: change set_bit to __set_bit etc. in preparation for introducing atomic bit operations, acked by perf maintainers; - MTE work that the ARM folks routed through Marc Zyngier's KVM tree. This also touches mm/ and fs/proc/page.c, in order to introduce a PG_arch_3 flag, only for 64-bit machines. The core ARM parts can be found at https://lore.kernel.org/all/20220705142619.4135905-1-catalin.marinas@arm.com/ if you're interested in the list of affected files; they were later rebased and extended with the KVM bits. Note that this is *not* a shared topic branch. There is another simple conflict due to the introduction of X86_FEATURE_SGX_EDECCSSA by the x86 maintainers, while my pull request is renaming the kvm_cpu_cap_init_scattered function to kvm_cpu_cap_init_kvm_defined. A shared topic branch with ARM, to introduce automatic generation of the system register headers, has been pulled already. KVM pull requests are getting bigger and I need to balance my other Red Hat work, improve the CI, and more in general get my act together. :/ I am working on it. Thanks, Paolo ---------------------------------------------------------------- ARM64: * Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. * Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. * Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87a97d: "Fix a number of issues with MTE, such as races on the tags being initialised vs the PG_mte_tagged flag as well as the lack of support for VM_SHARED when KVM is involved. Patches from Catalin Marinas and Peter Collingbourne"). * Merge the pKVM shadow vcpu state tracking that allows the hypervisor to have its own view of a vcpu, keeping that state private. * Add support for the PMUv3p5 architecture revision, bringing support for 64bit counters on systems that support it, and fix the no-quite-compliant CHAIN-ed counter support for the machines that actually exist out there. * Fix a handful of minor issues around 52bit VA/PA support (64kB pages only) as a prefix of the oncoming support for 4kB and 16kB pages. * Pick a small set of documentation and spelling fixes, because no good merge window would be complete without those. s390: * Second batch of the lazy destroy patches * First batch of KVM changes for kernel virtual != physical address support * Removal of a unused function x86: * Allow compiling out SMM support * Cleanup and documentation of SMM state save area format * Preserve interrupt shadow in SMM state save area * Respond to generic signals during slow page faults * Fixes and optimizations for the non-executable huge page errata fix. * Reprogram all performance counters on PMU filter change * Cleanups to Hyper-V emulation and tests * Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest running on top of a L1 Hyper-V hypervisor) * Advertise several new Intel features * x86 Xen-for-KVM: ** Allow the Xen runstate information to cross a page boundary ** Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured ** Add support for 32-bit guests in SCHEDOP_poll * Notable x86 fixes and cleanups: ** One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). ** Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. ** Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. ** Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. ** Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. ** Advertise (on AMD) that the SMM_CTL MSR is not supported ** Remove unnecessary exports Generic: * Support for responding to signals during page faults; introduces new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks Selftests: * Fix an inverted check in the access tracking perf test, and restore support for asserting that there aren't too many idle pages when running on bare metal. * Fix build errors that occur in certain setups (unsure exactly what is unique about the problematic setup) due to glibc overriding static_assert() to a variant that requires a custom message. * Introduce actual atomics for clear/set_bit() in selftests * Add support for pinning vCPUs in dirty_log_perf_test. * Rename the so called "perf_util" framework to "memstress". * Add a lightweight psuedo RNG for guest use, and use it to randomize the access pattern and write vs. read percentage in the memstress tests. * Add a common ucall implementation; code dedup and pre-work for running SEV (and beyond) guests in selftests. * Provide a common constructor and arch hook, which will eventually be used by x86 to automatically select the right hypercall (AMD vs. Intel). * A bunch of added/enabled/fixed selftests for ARM64, covering memslots, breakpoints, stage-2 faults and access tracking. * x86-specific selftest changes: ** Clean up x86's page table management. ** Clean up and enhance the "smaller maxphyaddr" test, and add a related test to cover generic emulation failure. ** Clean up the nEPT support checks. ** Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values. ** Fix an ordering issue in the AMX test introduced by recent conversions to use kvm_cpu_has(), and harden the code to guard against similar bugs in the future. Anything that tiggers caching of KVM's supported CPUID, kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if the caching occurs before the test opts in via prctl(). Documentation: * Remove deleted ioctls from documentation * Clean up the docs for the x86 MSR filter. * Various fixes ---------------------------------------------------------------- Aaron Lewis (5): KVM: x86: Disallow the use of KVM_MSR_FILTER_DEFAULT_ALLOW in the kernel KVM: x86: Add a VALID_MASK for the MSR exit reason flags KVM: x86: Add a VALID_MASK for the flag in kvm_msr_filter KVM: x86: Add a VALID_MASK for the flags in kvm_msr_filter_range selftests: kvm/x86: Test the flags in MSR filtering and MSR exiting Anshuman Khandual (1): KVM: arm64: PMU: Replace version number '0' with ID_AA64DFR0_EL1_PMUVer_NI Anton Romanov (1): KVM: x86: Use current rather than snapshotted TSC frequency if it is constant Carlos Bilbao (1): KVM: SVM: Name and check reserved fields with structs offset Catalin Marinas (4): mm: Do not enable PG_arch_2 for all 64-bit architectures arm64: mte: Fix/clarify the PG_mte_tagged semantics KVM: arm64: Simplify the sanitise_mte_tags() logic arm64: mte: Lock a page for MTE tag initialisation Chang S.
