In particular this broke virtio-gpu # blob resources (which directly map host graphics buffers into the # guest as "vram" for the virtio-gpu device) with the amdgpu driver, # because amdgpu allocates non-compound higher order pages and the tail # pages could not be mapped into KVM. # # This requires adjusting all uses of struct page in the # per-architecture code, to always work on the pfn whenever possible. # The large series that did this, from David Stevens and Sean # Christopherson, also cleaned up substantially the set of functions # that provided arch code with the pfn for a host virtual addresses. # # The previous maze of twisty little passages, all different, is # replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the # non-__ versions of these two, and kvm_prefetch_pages) saving almost # 200 lines of code. # # ARM: # # - Support for stage-1 permission indirection (FEAT_S1PIE) and # permission overlays (FEAT_S1POE), including nested virt + the # emulated page table walker # # - Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This # call was introduced in PSCIv1.3 as a mechanism to request # hibernation, similar to the S4 state in ACPI # # - Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As # part of it, introduce trivial initialization of the host's MPAM # context so KVM can use the corresponding traps # # - PMU support under nested virtualization, honoring the guest # hypervisor's trap configuration and event filtering when running a # nested guest # # - Fixes to vgic ITS serialization where stale device/interrupt table # entries are not zeroed when the mapping is invalidated by the VM # # - Avoid emulated MMIO completion if userspace has requested # synchronous external abort injection # # - Various fixes and cleanups affecting pKVM, vCPU initialization, and # selftests # # LoongArch: # # - Add iocsr and mmio bus simulation in kernel. # # - Add in-kernel interrupt controller emulation. # # - Add support for virtualization extensions to the eiointc irqchip. # # PPC: # # - Drop lingering and utterly obsolete references to PPC970 KVM, which # was removed 10 years ago. # # - Fix incorrect documentation references to non-existing ioctls # # RISC-V: # # - Accelerate KVM RISC-V when running as a guest # # - Perf support to collect KVM guest statistics from host side # # s390: # # - New selftests: more ucontrol selftests and CPU model sanity checks # # - Support for the gen17 CPU model # # - List registers supported by KVM_GET/SET_ONE_REG in the # documentation # # x86: # # - Cleanup KVM's handling of Accessed and Dirty bits to dedup code, # improve documentation, harden against unexpected changes. # # Even if the hardware A/D tracking is disabled, it is possible to # use the hardware-defined A/D bits to track if a PFN is Accessed # and/or Dirty, and that removes a lot of special cases. # # - Elide TLB flushes when aging secondary PTEs, as has been done in # x86's primary MMU for over 10 years. # # - Recover huge pages in-place in the TDP MMU when dirty page logging # is toggled off, instead of zapping them and waiting until the page # is re-accessed to create a huge mapping. This reduces vCPU jitter. # # - Batch TLB flushes when dirty page logging is toggled off. This # reduces the time it takes to disable dirty logging by ~3x. # # - Remove the shrinker that was (poorly) attempting to reclaim shadow # page tables in low-memory situations. # # - Clean up and optimize KVM's handling of writes to # MSR_IA32_APICBASE. # # - Advertise CPUIDs for new instructions in Clearwater Forest # # - Quirk KVM's misguided behavior of initialized certain feature MSRs # to their maximum supported feature set, which can result in KVM # creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to # a non-zero value results in the vCPU having invalid state if # userspace hides PDCM from the guest, which in turn can lead to # save/restore failures. # # - Fix KVM's handling of non-canonical checks for vCPUs that support # LA57 to better follow the "architecture", in quotes because the # actual behavior is poorly documented. E.g. most MSR writes and # descriptor table loads ignore CR4.LA57 and operate purely on # whether the CPU supports LA57. # # - Bypass the register cache when querying CPL from kvm_sched_out(), # as filling the cache from IRQ context is generally unsafe; harden # the cache accessors to try to prevent similar issues from occuring # in the future. The issue that triggered this change was already # fixed in 6.12, but was still kinda latent. # # - Advertise AMD_IBPB_RET to userspace, and fix a related bug where # KVM over-advertises SPEC_CTRL when trying to support cross-vendor # VMs. # # - Minor cleanups # # - Switch hugepage recovery thread to use vhost_task. # # These kthreads can consume significant amounts of CPU time on # behalf of a VM or in response to how the VM behaves (for example # how it accesses its memory); therefore KVM tried to place the # thread in the VM's cgroups and charge the CPU time consumed by that # work to the VM's container. # # However the kthreads did not process SIGSTOP/SIGCONT, and therefore # cgroups which had KVM instances inside could not complete freezing. # # Fix this by replacing the kthread with a PF_USER_WORKER thread, via # the vhost_task abstraction. Another 100+ lines removed, with # generally better behavior too like having these threads properly # parented in the process tree. # # - Revert a workaround for an old CPU erratum (Nehalem/Westmere) that # didn't really work; there was really nothing to work around anyway: # the broken patch was meant to fix nested virtualization, but the # PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the # erratum. # # - Fix 6.12 regression where CONFIG_KVM will be built as a module even # if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is # 'y'. # # x86 selftests: # # - x86 selftests can now use AVX. # # Documentation: # # - Use rST internal links # # - Reorganize the introduction to the API document # # Generic: # # - Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock # instead of RCU, so that running a vCPU on a different task doesn't # encounter long due to having to wait for all CPUs become quiescent. # # In general both reads and writes are rare, but userspace that # supports confidential computing is introducing the use of "helper" # vCPUs that may jump from one host processor to another. Those will # be very happy to trigger a synchronize_rcu(), and the effect on # performance is quite the disaster" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (298 commits) # KVM: x86: Break CONFIG_KVM_X86's direct dependency on KVM_INTEL \|\| KVM_AMD # KVM: x86: add back X86_LOCAL_APIC dependency # Revert "KVM: VMX: Move LOAD_IA32_PERF_GLOBAL_CTRL errata handling out of setup_vmcs_config()" # KVM: x86: switch hugepage recovery thread to vhost_task # KVM: x86: expose MSR_PLATFORM_INFO as a feature MSR # x86: KVM: Advertise CPUIDs for new instructions in Clearwater Forest # Documentation: KVM: fix malformed table # irqchip/loongson-eiointc: Add virt extension support # LoongArch: KVM: Add irqfd support # LoongArch: KVM: Add PCHPIC user mode read and write functions # LoongArch: KVM: Add PCHPIC read and write functions # LoongArch: KVM: Add PCHPIC device support # LoongArch: KVM: Add EIOINTC user mode read and write functions # LoongArch: KVM: Add EIOINTC read and write functions # LoongArch: KVM: Add EIOINTC device support # LoongArch: KVM: Add IPI user mode read and write function # LoongArch: KVM: Add IPI read and write function # LoongArch: KVM: Add IPI device support # LoongArch: KVM: Add iocsr and mmio bus simulation in kernel # KVM: arm64: Pass on SVE mapping failures # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 9f16d5e6f220661f73b36a4be1b21575651d8833 # make -s -j 160 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:15419:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 160 ARCH=mips O=/kisskb/build/linus_allmodconfig_mips-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.17-178.5: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0: '#interrupt-cells' found, but node is not an interrupt provider /kisskb/src/arch/mips/boot/dts/img/boston.dts:136.23-177.6: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0/eg20t_bridge@1,0,0: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/img/boston.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' ERROR: modpost: "__udivdi3" [drivers/gpu/drm/rockchip/rockchipdrm.ko] undefined!
