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" ...

tools: arm64: Update sysreg.h header files

2025-01-12T12:50:11Z

Created with the following: cp include/linux/kasan-tags.h tools/include/linux/ cp arch/arm64/include/asm/sysreg.h tools/arch/arm64/include/asm/ Update the tools copy of sysreg.h so that the next commit to add a new register doesn't have unrelated changes in it. Because the new version of sysreg.h includes kasan-tags.h, that file also now needs to be copied into tools.

bpftool: Probe for ISA v4 instruction set extension

2024-12-12T16:25:17Z

This patch introduces a new probe to check whether the kernel supports instruction set extensions v4. The v4 extension comprises several new instructions: BPF_{SDIV,SMOD} (signed div and mod), BPF_{LD,LDX,ST,STX,MOV} (sign-extended load/store/move), 32-bit BPF_JA (unconditional jump), target-independent BPF_ALU64 BSWAP (byte-swapping 16/32/64). These have been introduced in the following commits respectively: * ec0e2da95f72 ("bpf: Support new signed div/mod instructions.") * 1f9a1ea821ff ("bpf: Support new sign-extension load insns") * 8100928c8814 ("bpf: Support new sign-extension mov insns") * 4cd58e9af8b9 ("bpf: Support new 32bit offset jmp instruction") * 0845c3db7bf5 ("bpf: Support new unconditional bswap instruction") Support in bpftool for previous ISA extensions was added in commit 0fd800b2456c ("bpftool: Probe for instruction set extensions"). These probes are useful for userspace BPF projects that want to use newer instruction set extensions on newer kernels, to reduce the programs' sizes or their complexity. LLVM provides the mcpu=v4 option since LLVM commit 8f28e8069c4b ("[BPF] support for BPF_ST instruction in codegen") [0].
