There is a spelling mistake in a literal string and in the function test_get_inital_dirty. Fix them. Signed-off-by: Colin Ian King Message-ID: <20250204105647.367743-1-colin.i.king@gmail.com> Signed-off-by: Paolo Bonzini

KVM: s390: selftests: Streamline uc_skey test to issue iske after sske

2025-01-31T11:03:53Z

In some rare situations a non default storage key is already set on the memory used by the test. Within normal VMs the key is reset / zapped when the memory is added to the VM. This is not the case for ucontrol VMs. With the initial iske check removed this test case can work in all situations. The function of the iske instruction is still validated by the remaining code.

KVM: s390: selftests: fix ucontrol memory region test

2025-01-31T11:03:52Z

With the latest patch, attempting to create a memslot from userspace will result in an EEXIST error for UCONTROL VMs, instead of EINVAL, since the new memslot will collide with the internal memslot. There is no simple way to bring back the previous behaviour. This is not a problem, but the test needs to be fixed accordingly.

Pull KVM/arm64 updates from Will Deacon: "New features: - Support for non-protected guest in protected mode, achieving near feature parity with the non-protected mode - Support for the EL2 timers as part of the ongoing NV support - Allow control of hardware tracing for nVHE/hVHE Improvements, fixes and cleanups: - Massive cleanup of the debug infrastructure, making it a bit less awkward and definitely easier to maintain. This should pave the way for further optimisations - Complete rewrite of pKVM's fixed-feature infrastructure, aligning it with the rest of KVM and making the code easier to follow - Large simplification of pKVM's memory protection infrastructure - Better handling of RES0/RES1 fields for memory-backed system registers - Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer from a pretty nasty timer bug - Small collection of cleanups and low-impact fixes" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (87 commits) arm64/sysreg: Get rid of TRFCR_ELx SysregFields KVM: arm64: nv: Fix doc header layout for timers KVM: arm64: nv: Apply RESx settings to sysreg reset values KVM: arm64: nv: Always evaluate HCR_EL2 using sanitising accessors KVM: arm64: Fix selftests after sysreg field name update coresight: Pass guest TRFCR value to KVM KVM: arm64: Support trace filtering for guests KVM: arm64: coresight: Give TRBE enabled state to KVM coresight: trbe: Remove redundant disable call arm64/sysreg/tools: Move TRFCR definitions to sysreg tools: arm64: Update sysreg.h header files KVM: arm64: Drop pkvm_mem_transition for host/hyp donations KVM: arm64: Drop pkvm_mem_transition for host/hyp sharing KVM: arm64: Drop pkvm_mem_transition for FF-A KVM: arm64: Explicitly handle BRBE traps as UNDEFINED KVM: arm64: vgic: Use str_enabled_disabled() in vgic_v3_probe() arm64: kvm: Introduce nvhe stack size constants KVM: arm64: Fix nVHE stacktrace VA bits mask KVM: arm64: Fix FEAT_MTE in pKVM Documentation: Update the behaviour of "kvm-arm.mode" ...

KVM x86 misc changes for 6.14: - 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.
