(Christophe JAILLET) - Add ID for an additional hardware SKU supported by the nvgrace-gpu vfio-pci variant driver. (Ankit Agrawal) - Fix incorrect signed cast in QAT vfio-pci variant driver, negating test in check_add_overflow(), though still caught by later tests. (Giovanni Cabiddu) - Additional debugfs attributes exposed in hisi_acc vfio-pci variant driver for migration debugging. (Longfang Liu) - Migration support is added to the virtio vfio-pci variant driver, becoming the primary feature of the driver while retaining emulation of virtio legacy support as a secondary option.

You have merged both so this is the remainder. It has been in linux-next since before you pulled from Joerg. I left it based with my merge of Joerg's tree to iommufd rather than rebasing it to your merge of Joerg's tree. Due to the many different driver trees in iommu it is helpful if global changes like this make -rc1.

As a result, all commits were *just* rebased, like 5 minutes ago. I smoke tested the branch, but didn't do anywhere near my usual level of testing. I'm sending it now, because I suspect it'll be far easier on you to get this today, and because we've probably got bigger problems if these don't work on kvm/master. *sigh* The following changes since commit 7d4050728c83aa63828494ad0f4d0eb4faf5f97a: Merge tag 'vfs-6.13-rc1.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs (2024-11-27 08:11:46 -0800) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-fixes-6.13-rcN for you to fetch changes up to 386d69f9f29b0814881fa4f92ac7b8dfa9b4f44a: KVM: x86/mmu: Treat TDP MMU faults as spurious if access is already allowed (2024-12-19 17:47:52 -0800) ---------------------------------------------------------------- KVM x86 fixes for 6.13: - Disable AVIC on SNP-enabled systems that don't allow writes to the virtual APIC page, as such hosts will hit unexpected RMP #PFs in the host when running VMs of any flavor. - Fix a WARN in the hypercall completion path due to KVM trying to determine if a guest with protected register state is in 64-bit mode (KVM's ABI is to assume such guests only make hypercalls in 64-bit mode). - Allow the guest to write to supported bits in MSR_AMD64_DE_CFG to fix a regression with Windows guests, and because KVM's read-only behavior appears to be entirely made up. - Treat TDP MMU faults as spurious if the faulting access is allowed given the existing SPTE.

There's some "holiday-induced lateness", as the s390 submaintainer put it, but otherwise things looks fine. ---------------------------------------------------------------- s390: * fix a latent bug when the kernel is compiled in debug mode * two small UCONTROL fixes and their selftests arm64: * always check page state in hyp_ack_unshare() * align set_id_regs selftest with the fact that ASIDBITS field is RO * various vPMU fixes for bugs that only affect nested virt PPC e500: * Fix a mostly impossible (but just wrong) case where IRQs were never re-enabled * Observe host permissions instead of mapping readonly host pages as guest-writable. This fixes a NULL-pointer dereference in 6.13 * Replace brittle VMA-based attempts at building huge shadow TLB entries with PTE lookups. ---------------------------------------------------------------- Christoph Schlameuss (5): KVM: s390: Reject setting flic pfault attributes on ucontrol VMs KVM: s390: selftests: Add ucontrol flic attr selftests KVM: s390: Reject KVM_SET_GSI_ROUTING on ucontrol VMs KVM: s390: selftests: Add ucontrol gis routing test KVM: s390: selftests: Add has device attr check to uc_attr_mem_limit selftest Claudio Imbrenda (1): KVM: s390: vsie: fix virtual/physical address in unpin_scb() Mark Brown (1): KVM: arm64: Fix set_id_regs selftest for ASIDBITS becoming unwritable Oliver Upton (4): KVM: arm64: Add unified helper for reprogramming counters by mask KVM: arm64: Use KVM_REQ_RELOAD_PMU to handle PMCR_EL0.E change KVM: arm64: nv: Reload PMU events upon MDCR_EL2.HPME change KVM: arm64: Only apply PMCR_EL0.P to the guest range of counters Paolo Bonzini (8): KVM: e500: always restore irqs KVM: e500: use shadow TLB entry as witness for writability KVM: e500: track host-writability of pages KVM: e500: map readonly host pages for read KVM: e500: perform hugepage check after looking up the PFN Merge branch 'kvm-e500-check-writable-pfn' into HEAD Merge tag 'kvmarm-fixes-6.13-3' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD Merge tag 'kvm-s390-master-6.13-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD Quentin Perret (1): KVM: arm64: Always check the state from hyp_ack_unshare() Documentation/virt/kvm/api.rst | 3 + Documentation/virt/kvm/devices/s390_flic.rst | 4 + arch/arm64/kvm/hyp/nvhe/mem_protect.c | 3 - arch/arm64/kvm/pmu-emul.c | 91 ++++------ arch/arm64/kvm/sys_regs.c | 32 +++- arch/powerpc/kvm/e500.h | 2 + arch/powerpc/kvm/e500_mmu_host.c | 199 +++++++++------------- arch/s390/kvm/interrupt.c | 6 + arch/s390/kvm/vsie.c | 2 +- include/kvm/arm_pmu.h | 6 +- tools/testing/selftests/kvm/aarch64/set_id_regs.c | 1 - tools/testing/selftests/kvm/s390x/ucontrol_test.c | 172 ++++++++++++++++++- 12 files changed, 333 insertions(+), 188 deletions(-) .

Thanks, Paolo ---------------------------------------------------------------- Loongarch: * Clear LLBCTL if secondary mmu mapping changes. * Add hypercall service support for usermode VMM. x86: * Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a direct call to kvm_tdp_page_fault() when RETPOLINE is enabled. * Ensure that all SEV code is compiled out when disabled in Kconfig, even if building with less brilliant compilers. * Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes. * Use str_enabled_disabled() to replace open coded strings. * Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache prior to every VM-Enter. * Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities instead of just those where KVM needs to manage state and/or explicitly enable the feature in hardware. Along the way, refactor the code to make it easier to add features, and to make it more self-documenting how KVM is handling each feature. * Rework KVM's handling of VM-Exits during event vectoring; this plugs holes where KVM unintentionally puts the vCPU into infinite loops in some scenarios (e.g. if emulation is triggered by the exit), and brings parity between VMX and SVM. * Add pending request and interrupt injection information to the kvm_exit and kvm_entry tracepoints respectively. * Fix a relatively benign flaw where KVM would end up redoing RDPKRU when loading guest/host PKRU, due to a refactoring of the kernel helpers that didn't account for KVM's pre-checking of the need to do WRPKRU. * Make the completion of hypercalls go through the complete_hypercall function pointer argument, no matter if the hypercall exits to userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE specifically went to userspace, and all the others did not; the new code need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at all whether there was an exit to userspace or not. * As part of enabling TDX virtual machines, support support separation of private/shared EPT into separate roots. When TDX will be enabled, operations on private pages will need to go through the privileged TDX Module via SEAMCALLs; as a result, they are limited and relatively slow compared to reading a PTE. The patches included in 6.14 allow KVM to keep a mirror of the private EPT in host memory, and define entries in kvm_x86_ops to operate on external page tables such as the TDX private EPT. * The recently introduced conversion of the NX-page reclamation kthread to vhost_task moved the task under the main process. The task is created as soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that didn't expect to see any child task of the VM process until it started creating its own userspace threads. In particular crosvm refuses to fork() if procfs shows any child task, so unbreak it by creating the task lazily. This is arguably a userspace bug, as there can be other kinds of legitimate worker tasks and they wouldn't impede fork(); but it's not like userspace has a way to distinguish kernel worker tasks right now. Should they show as "Kthread: 1" in proc/.../status? x86 - Intel: * Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit while L2 is active, while ultimately results in a hardware-accelerated L1 EOI effectively being lost. * Honor event priority when emulating Posted Interrupt delivery during nested VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the interrupt. * Rework KVM's processing of the Page-Modification Logging buffer to reap entries in the same order they were created, i.e. to mark gfns dirty in the same order that hardware marked the page/PTE dirty. * Misc cleanups. Generic: * Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when setting memory regions and add a dedicated API for setting KVM-internal memory regions. The API can then explicitly disallow all flags for KVM-internal memory regions. * Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug where KVM would return a pointer to a vCPU prior to it being fully online, and give kvm_for_each_vcpu() similar treatment to fix a similar flaw. * Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a bug where userspace could coerce KVM into handling the ioctl on a vCPU that isn't yet onlined. * Gracefully handle xarray insertion failures; even though such failures are impossible in practice after xa_reserve(), reserving an entry is always followed by xa_store() which does not know (or differentiate) whether there was an xa_reserve() before or not. RISC-V: * Zabha, Svvptc, and Ziccrse extension support for guests. None of them require anything in KVM except for detecting them and marking them as supported; Zabha adds byte and halfword atomic operations, while the others are markers for specific operation of the TLB and of LL/SC instructions respectively. * Virtualize SBI system suspend extension for Guest/VM * Support firmware counters which can be used by the guests to collect statistics about traps that occur in the host. Selftests: * Rework vcpu_get_reg() to return a value instead of using an out-param, and update all affected arch code accordingly. * Convert the max_guest_memory_test into a more generic mmu_stress_test. The basic gist of the "conversion" is to have the test do mprotect() on guest memory while vCPUs are accessing said memory, e.g. to verify KVM and mmu_notifiers are working as intended. * Play nice with treewrite builds of unsupported architectures, e.g. arm (32-bit), as KVM selftests' Makefile doesn't do anything to ensure the target architecture is actually one KVM selftests supports. * Use the kernel's $(ARCH) definition instead of the target triple for arch specific directories, e.g. arm64 instead of aarch64, mainly so as not to be different from the rest of the kernel. * Ensure that format strings for logging statements are checked by the compiler even when the logging statement itself is disabled. * Attempt to whack the last LLC references/misses mole in the Intel PMU counters test by adding a data load and doing CLFLUSH{OPT} on the data instead of the code being executed. It seems that modern Intel CPUs have learned new code prefetching tricks that bypass the PMU counters. * Fix a flaw in the Intel PMU counters test where it asserts that events are counting correctly without actually knowing what the events count given the underlying hardware; this can happen if Intel reuses a formerly microarchitecture-specific event encoding as an architectural event, as was the case for Top-Down Slots. ---------------------------------------------------------------- Adrian Hunter (1): KVM: VMX: Allow toggling bits in MSR_IA32_RTIT_CTL when enable bit is cleared Andrew Jones

(Ramesh Thomas) - Update vfio-pci shadow ROM handling and allow cached ROM from setup data to be exposed as a functional ROM BAR region when available. (Yunxiang Li) - Update nvgrace-gpu vfio-pci variant driver for new Grace Blackwell hardware, conditionalizing the uncached BAR workaround for previous generation hardware based on the presence of a flag in a new DVSEC capability, and include a delay during probe for link training to complete, a new requirement for GB devices.
