[PATCH v7 0/7] rust: reduce `as` casts, enable related lints

by Tamir Duberstein

This started with a patch that enabled `clippy::ptr_as_ptr`. Benno Lossin suggested I also look into `clippy::ptr_cast_constness` and I discovered `clippy::as_ptr_cast_mut`. This series now enables all 3 lints. It also enables `clippy::as_underscore` which ensures other pointer casts weren't missed. The first commit reduces the need for pointer casts and is shared with another series[1]. As a later addition, `clippy::cast_lossless` and `clippy::ref_as_ptr` are also enabled.

[PATCH] selftest/mm: va_high_addr_switch: add ppc64 support check

by Li Wang

This patch adds PPC64 Radix MMU support to the va_high_addr_switch.sh by introducing check_supported_ppc64(). The function verifies: - 5-level paging (PGTABLE_LEVELS >= 5) enable in kernel config - Radix MMU (required for PPC64 5-level translation) - HugePages availability (needed for some tests) If any check fails, the test is skipped (ksft_skip). This ensures compatibility with Power9/Power10 systems running in Radix MMU mode. Avoid failures on 4-level paging system: # mmap(NULL, MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(LOW_ADDR, MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(HIGH_ADDR, MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(HIGH_ADDR, MAP_HUGETLB) again: 0xffffffffffffffff - FAILED # mmap(HIGH_ADDR, MAP_FIXED | MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(-1, MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(-1, MAP_HUGETLB) again: 0xffffffffffffffff - FAILED # mmap(ADDR_SWITCH_HINT - PAGE_SIZE, 2*HUGETLB_SIZE, MAP_HUGETLB): 0xffffffffffffffff - FAILED # mmap(ADDR_SWITCH_HINT , 2*HUGETLB_SIZE, MAP_FIXED | MAP_HUGETLB): 0xffffffffffffffff - FAILED Signed-off-by: Li Wang <liwang(a)redhat.com> --- .../selftests/mm/va_high_addr_switch.sh | 28 +++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/tools/testing/selftests/mm/va_high_addr_switch.sh b/tools/testing/selftests/mm/va_high_addr_switch.sh index 2c725773cd79..1f92e8caceac 100755 --- a/tools/testing/selftests/mm/va_high_addr_switch.sh +++ b/tools/testing/selftests/mm/va_high_addr_switch.sh @@ -41,6 +41,31 @@ check_supported_x86_64() fi } +check_supported_ppc64() +{ + local config="/proc/config.gz" + [[ -f "${config}" ]] || config="/boot/config-$(uname -r)" + [[ -f "${config}" ]] || fail "Cannot find kernel config in /proc or /boot" + + local pg_table_levels=$(gzip -dcfq "${config}" | grep PGTABLE_LEVELS | cut -d'=' -f 2) + if [[ "${pg_table_levels}" -lt 5 ]]; then + echo "$0: PGTABLE_LEVELS=${pg_table_levels}, must be >= 5 to run this test" + exit $ksft_skip + fi + + local mmu_support=$(grep -m1 "mmu" /proc/cpuinfo | awk '{print $3}') + if [[ "$mmu_support" != "radix" ]]; then + echo "$0: System does not use Radix MMU, required for 5-level paging" + exit $ksft_skip + fi + + local hugepages_total=$(awk '/HugePages_Total/ {print $2}' /proc/meminfo) + if [[ "${hugepages_total}" -eq 0 ]]; then + echo "$0: HugePages are not enabled, required for some tests" + exit $ksft_skip + fi +} + check_test_requirements() { # The test supports x86_64 and powerpc64.

[RFC PATCH v3 0/8] PMU partitioning driver support

by Colton Lewis

This series introduces support in the KVM and ARM PMUv3 driver for partitioning PMU counters into two separate ranges by taking advantage of the MDCR_EL2.HPMN register field. The advantage of a partitioned PMU would be to allow KVM guests direct access to a subset of PMU functionality, greatly reducing the overhead of performance monitoring in guests. While this feature could be accepted on its own merits, practically there is a lot more to be done before it will be fully useful, so I'm sending as an RFC for now. v3: * Include cpucap definition for FEAT_HPMN0 to allow for setting HPMN to 0 * Include PMU header cleanup provided by Marc [1] with some minor changes so compilation works * Pull functions out of pmu-emul.c that aren't specific to the emulated PMU. This and the previous item aren't strictly needed but they provide a nicer starting point. * As suggested by Oliver, start a file for partitioned PMU functions and move the reserved_host_counters parameter and MDCR handling into KVM so the driver does not have to know about it and we need fewer hacks to keep the driver working on 32-bit ARM. This was not a complete separation because the driver still needs to start and stop the host counters all at once and needs to toggle MDCR_EL2.HPME to do that. Introduce kvm_pmu_host_counters_{enable,disable}() functions to handle this and define them as no ops on 32-bit ARM. * As suggested by Oliver, don't limit PMCR.N on emulated PMU. This value will be read correctly when the right traps are disabled to use the partitioned PMU v2: https://lore.kernel.org/kvm/20250208020111.2068239-1-coltonlewis@google.com/ v1: https://lore.kernel.org/kvm/20250127222031.3078945-1-coltonlewis@google.com/ [1] https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?… Colton Lewis (7): arm64: cpufeature: Add cap for HPMN0 arm64: Generate sign macro for sysreg Enums KVM: arm64: Reorganize PMU functions KVM: arm64: Introduce module param to partition the PMU perf: arm_pmuv3: Generalize counter bitmasks perf: arm_pmuv3: Keep out of guest counter partition KVM: arm64: selftests: Reword selftests error Marc Zyngier (1): KVM: arm64: Cleanup PMU includes arch/arm/include/asm/arm_pmuv3.h | 2 + arch/arm64/include/asm/arm_pmuv3.h | 2 +- arch/arm64/include/asm/kvm_host.h | 199 +++++++- arch/arm64/include/asm/kvm_pmu.h | 47 ++ arch/arm64/kernel/cpufeature.c | 8 + arch/arm64/kvm/Makefile | 2 +- arch/arm64/kvm/arm.c | 1 - arch/arm64/kvm/debug.c | 10 +- arch/arm64/kvm/hyp/include/hyp/switch.h | 1 + arch/arm64/kvm/pmu-emul.c | 464 +----------------- arch/arm64/kvm/pmu-part.c | 63 +++ arch/arm64/kvm/pmu.c | 454 +++++++++++++++++ arch/arm64/kvm/sys_regs.c | 2 + arch/arm64/tools/cpucaps | 1 + arch/arm64/tools/gen-sysreg.awk | 1 + arch/arm64/tools/sysreg | 6 +- drivers/perf/arm_pmuv3.c | 73 ++- include/kvm/arm_pmu.h | 204 -------- include/linux/perf/arm_pmu.h | 16 +- include/linux/perf/arm_pmuv3.h | 27 +- .../selftests/kvm/arm64/vpmu_counter_access.c | 2 +- virt/kvm/kvm_main.c | 1 + 22 files changed, 882 insertions(+), 704 deletions(-) create mode 100644 arch/arm64/include/asm/kvm_pmu.h create mode 100644 arch/arm64/kvm/pmu-part.c delete mode 100644 include/kvm/arm_pmu.h base-commit: 2014c95afecee3e76ca4a56956a936e23283f05b -- 2.48.1.601.g30ceb7b040-goog
