Wed, 15 Apr 2026 01:48:56 +0200

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linuxPull arm64 updates from Catalin Marinas: "The biggest changes are MPAM enablement in drivers/resctrl and new PMU support under drivers/perf. On the core side, FEAT_LSUI lets futex atomic operations with EL0 permissions, avoiding PAN toggling. The rest is mostly TLB invalidation refactoring, further generic entry work, sysreg updates and a few fixes. Core features: - Add support for FEAT_LSUI, allowing futex atomic operations without toggling Privileged Access Never (PAN) - Further refactor the arm64 exception handling code towards the generic entry infrastructure - Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis through it Memory management: - Refactor the arm64 TLB invalidation API and implementation for better control over barrier placement and level-hinted invalidation - Enable batched TLB flushes during memory hot-unplug - Fix rodata=full block mapping support for realm guests (when BBML2_NOABORT is available) Perf and PMU: - Add support for a whole bunch of system PMUs featured in NVIDIA's Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers for CPU/C2C memory latency PMUs) - Clean up iomem resource handling in the Arm CMN driver - Fix signedness handling of AA64DFR0.{PMUVer,PerfMon} MPAM (Memory Partitioning And Monitoring): - Add architecture context-switch and hiding of the feature from KVM - Add interface to allow MPAM to be exposed to user-space using resctrl - Add errata workaround for some existing platforms - Add documentation for using MPAM and what shape of platforms can use resctrl Miscellaneous: - Check DAIF (and PMR, where relevant) at task-switch time - Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode (only relevant to asynchronous or asymmetric tag check modes) - Remove a duplicate allocation in the kexec code - Remove redundant save/restore of SCS SP on entry to/from EL0 - Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap descriptions - Add kselftest coverage for cmpbr_sigill() - Update sysreg definitions"* tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (109 commits) arm64: rsi: use linear-map alias for realm config buffer arm64: Kconfig: fix duplicate word in CMDLINE help text arm64: mte: Skip TFSR_EL1 checks and barriers in synchronous tag check mode arm64/sysreg: Update ID_AA64SMFR0_EL1 description to DDI0601 2025-12 arm64/sysreg: Update ID_AA64ZFR0_EL1 description to DDI0601 2025-12 arm64/sysreg: Update ID_AA64FPFR0_EL1 description to DDI0601 2025-12 arm64/sysreg: Update ID_AA64ISAR2_EL1 description to DDI0601 2025-12 arm64/sysreg: Update ID_AA64ISAR0_EL1 description to DDI0601 2025-12 arm64/hwcap: Generate the KERNEL_HWCAP_ definitions for the hwcaps arm64: kexec: Remove duplicate allocation for trans_pgd ACPI: AGDI: fix missing newline in error message arm64: Check DAIF (and PMR) at task-switch time arm64: entry: Use split preemption logic arm64: entry: Use irqentry_{enter_from,exit_to}_kernel_mode() arm64: entry: Consistently prefix arm64-specific wrappers arm64: entry: Don't preempt with SError or Debug masked entry: Split preemption from irqentry_exit_to_kernel_mode() entry: Split kernel mode logic from irqentry_{enter,exit}() entry: Move irqentry_enter() prototype later entry: Remove local_irq_{enable,disable}_exit_to_user() ...

Fri, 13 Mar 2026 15:45:51 +0100

arm_mpam: resctrl: Add boilerplate cpuhp and domain allocationresctrl has its own data structures to describe its resources. We can't usethese directly as we play tricks with the 'MBA' resource, picking the MPAMcontrols or monitors that best apply. We may export the same component asboth L3 and MBA.Add mpam_resctrl_res[] as the array of class->resctrl mappings we areexporting, and add the cpuhp hooks that allocated and free the resctrldomain structures. Only the mpam control feature are considered here andmonitor support will be added later.While we're here, plumb in a few other obvious things.CONFIG_ARM_CPU_RESCTRL is used to allow this code to be built even thoughit can't yet be linked against resctrl.Tested-by: Gavin Shan Tested-by: Shaopeng Tan Tested-by: Peter Newman Tested-by: Zeng Heng Tested-by: Punit Agrawal Tested-by: Jesse Chick Reviewed-by: Zeng Heng Reviewed-by: Shaopeng Tan Reviewed-by: Jonathan Cameron Reviewed-by: Gavin Shan Co-developed-by: Ben Horgan Signed-off-by: Ben Horgan Signed-off-by: James Morse List of files: /linux/drivers/resctrl/Makefile

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linuxPull arm64 updates from Catalin Marinas: "These are the arm64 updates for 6.19. The biggest part is the Arm MPAM driver under drivers/resctrl/. There's a patch touching mm/ to handle spurious faults for huge pmd (similar to the pte version). The corresponding arm64 part allows us to avoid the TLB maintenance if a (huge) page is reused after a write fault. There's EFI refactoring to allow runtime services with preemption enabled and the rest is the usual perf/PMU updates and several cleanups/typos. Summary: Core features: - Basic Arm MPAM (Memory system resource Partitioning And Monitoring) driver under drivers/resctrl/ which makes use of the fs/rectrl/ API Perf and PMU: - Avoid cycle counter on multi-threaded CPUs - Extend CSPMU device probing and add additional filtering support for NVIDIA implementations - Add support for the PMUs on the NoC S3 interconnect - Add additional compatible strings for new Cortex and C1 CPUs - Add support for data source filtering to the SPE driver - Add support for i.MX8QM and "DB" PMU in the imx PMU driver Memory managemennt: - Avoid broadcast TLBI if page reused in write fault - Elide TLB invalidation if the old PTE was not valid - Drop redundant cpu_set_*_tcr_t0sz() macros - Propagate pgtable_alloc() errors outside of __create_pgd_mapping() - Propagate return value from __change_memory_common() ACPI and EFI: - Call EFI runtime services without disabling preemption - Remove unused ACPI function Miscellaneous: - ptrace support to disable streaming on SME-only systems - Improve sysreg generation to include a 'Prefix' descriptor - Replace __ASSEMBLY__ with __ASSEMBLER__ - Align register dumps in the kselftest zt-test - Remove some no longer used macros/functions - Various spelling corrections"* tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (94 commits) arm64/mm: Document why linear map split failure upon vm_reset_perms is not problematic arm64/pageattr: Propagate return value from __change_memory_common arm64/sysreg: Remove unused define ARM64_FEATURE_FIELD_BITS KVM: arm64: selftests: Consider all 7 possible levels of cache KVM: arm64: selftests: Remove ARM64_FEATURE_FIELD_BITS and its last user arm64: atomics: lse: Remove unused parameters from ATOMIC_FETCH_OP_AND macros Documentation/arm64: Fix the typo of register names ACPI: GTDT: Get rid of acpi_arch_timer_mem_init() perf: arm_spe: Add support for filtering on data source perf: Add perf_event_attr::config4 perf/imx_ddr: Add support for PMU in DB (system interconnects) perf/imx_ddr: Get and enable optional clks perf/imx_ddr: Move ida_alloc() from ddr_perf_init() to ddr_perf_probe() dt-bindings: perf: fsl-imx-ddr: Add compatible string for i.MX8QM, i.MX8QXP and i.MX8DXL arm64: remove duplicate ARCH_HAS_MEM_ENCRYPT arm64: mm: use untagged address to calculate page index MAINTAINERS: new entry for MPAM Driver arm_mpam: Add kunit tests for props_mismatch() arm_mpam: Add kunit test for bitmap reset arm_mpam: Add helper to reset saved mbwu state ...
