[PATCH 0/3] perf tools: Add libdw DWARF post unwind support for ARM64

by Jean Pihet

Adding libdw DWARF post unwind support, which is part of elfutils-devel/libdw-dev package from version 0.158. Also includes the test suite for dwarf unwinding, by adding the arch specific test code and the perf_regs_load function. This series depends on the following kernel patches series: - AARCH64 unwinding support [1], - ARM libdw integration [2], and on the changes from the branch for: - libdw AARCH64 unwinding support [3].

[PATCH 0/3] context tracker support for arm64

by Larry Bassel

Implement and enable context tracking for arm64 (which is a prerequisite for FULL_NOHZ support). This patchset builds upon earlier work by Kevin Hilman and is based on 3.15-rc2.

Bare metal Code to test Big Little on Arndale Octa (5420)

by armdev

Hi, We are trying a write a bare metal test code for Switching tasks from A15 Core to A7 core. As of now we have this article to start with https://lwn.net/Articles/481055/. Can the list help us in a) Where (file/directory ) in Linux kernel code that does the switching code (arch specific) for 5420 ? b) Any test cases for big little on 5420 ? -Regards armdev team

[PATCH 0/3] sched: idle: Provide the basis to integrate cpuidle

by Daniel Lezcano

This patchset provides three patches for the basis to integrate cpuidle with the scheduler. The first patch is a cleanup. The second one adds the sched balance option as requested by Ingo. The third one stores the idle state a cpu is and adds a rcu_barrier() to prevent races when using the pointed object. This patchset is based on top of v3.15-rc2. This patchset does not modify the behavior of the scheduler. Taking into account the cpuidle information from the scheduler will be posted in a separate patchset in order to keep focused on the right decisions the scheduler should take regarding the policy vs idle parameters.

[PATCH v2] PM / Hibernate: no kernel_power_off when pm_power_off NULL

by Sebastian Capella

Reboot logic in kernel/reboot will avoid calling kernel_power_off when pm_power_off is null, and instead uses kernel_halt. Change hibernate's power_down to follow the behavior in the reboot call. Calling the notifier twice (once for SYS_POWER_OFF and again for SYS_HALT) causes a panic during hibernation on Kirkwood Openblocks A6 board.

ARMv8: Allowing user space to perform cache-maintenance

by Rajan Srivastava

ARMv8 allows AArch64-EL0 to execute cache maintenance instructions (eg, by setting SCTLR_EL1.UCI). It looks like the current ARMv8 kernel doesn't support the above feature. Is there any plan in Linux for allowing AArch64_EL0 to perform cache-line operations? Regards, Rajan

[PATCH v11 00/12] In-kernel PSCI v0.2 emulation for KVM ARM/ARM64

by Anup Patel

Currently, KVM ARM/ARM64 only provides in-kernel emulation of Power State and Coordination Interface (PSCI) v0.1. This patchset aims at providing newer PSCI v0.2 for KVM ARM/ARM64 VCPUs such that it does not break current KVM ARM/ARM64 ABI. The user space tools (i.e. QEMU or KVMTOOL) will have to explicitly enable KVM_ARM_VCPU_PSCI_0_2 feature using KVM_ARM_VCPU_INIT ioctl for providing PSCI v0.2 to VCPUs. Changlog: V11: - Added more comments to uapi/linux/psci.h - Added comment about why we store INTERNAL_FAILURE in r0 (or x0) for SYSTEM_OFF and SYSTEM_RESET emulation V10: - Updated PSCI_VERSION_xxx defines in uapi/linux/psci.h - Added PSCI_0_2_AFFINITY_LEVEL_xxxx defines in uapi/linux/psci.h - Removed PSCI v0.1 related defines from uapi/linux/psci.h - Inject undefined exception for all types of errors in PSCI emulation (i.e kvm_psci_call(vcpu) < 0) - Removed "inline" attribute of kvm_prepare_system_event() - Store INTERNAL_FAILURE in r0 (or x0) before exiting to userspace - Use MPIDR_LEVEL_BITS in AFFINITY_MASK define - Updated comment in kvm_psci_vcpu_suspend() as-per Marc's suggestion V9: - Rename undefined PSCI_VER_xxx defines to PSCI_VERSION_xxx defines V8: - Add #define for possible values of migrate type in uapi/linux/psci.h - Simplified psci_affinity_mask() in psci.c - Update comments in kvm_psci_vcpu_suspend() to indicate that for KVM wakeup events are interrupts. - Unconditionally update r0 (or x0) in kvm_psci_vcpu_on() V7: - Make uapi/linux/psci.h inline with Ashwin's patch http://www.spinics.net/lists/arm-kernel/msg319090.html - Incorporate Rob's suggestions for uapi/linux/psci.h - Treat CPU_SUSPEND power-down request to be same as standby request. This further simplifies CPU_SUSPEND emulation. V6: - Introduce uapi/linux/psci.h for sharing PSCI defines between ARM kernel, ARM64 kernel, KVM ARM/ARM64 and user space - Make CPU_SUSPEND emulation similar to WFI emulation V5: - Have separate last patch to advertise KVM_CAP_ARM_PSCI_0_2 - Use kvm_psci_version() in kvm_psci_vcpu_on() - Return ALREADY_ON for PSCI v0.2 CPU_ON if VCPU is not paused - Remove per-VCPU suspend context - As-per PSCI v0.2 spec, only current CPU can suspend itself V4: - Implement all mandatory functions required by PSCI v0.2 V3: - Make KVM_ARM_VCPU_PSCI_0_2 feature experiementatl for now so that it fails for user space till all mandatory PSCI v0.2 functions are emulated by KVM ARM/ARM64 - Have separate patch for making KVM_ARM_VCPU_PSCI_0_2 feature available to user space. This patch can be defferred for now V2: - Don't rename PSCI return values KVM_PSCI_RET_NI and KVM_PSCI_RET_INVAL - Added kvm_psci_version() to get PSCI version available to VCPU - Fixed grammer in Documentation/virtual/kvm/api.txt V1: - Initial RFC PATCH Anup Patel (12): KVM: Add capability to advertise PSCI v0.2 support ARM/ARM64: KVM: Add common header for PSCI related defines ARM/ARM64: KVM: Add base for PSCI v0.2 emulation KVM: Documentation: Add info regarding KVM_ARM_VCPU_PSCI_0_2 feature ARM/ARM64: KVM: Make kvm_psci_call() return convention more flexible KVM: Add KVM_EXIT_SYSTEM_EVENT to user space API header ARM/ARM64: KVM: Emulate PSCI v0.2 SYSTEM_OFF and SYSTEM_RESET ARM/ARM64: KVM: Emulate PSCI v0.2 AFFINITY_INFO ARM/ARM64: KVM: Emulate PSCI v0.2 MIGRATE_INFO_TYPE and related functions ARM/ARM64: KVM: Fix CPU_ON emulation for PSCI v0.2 ARM/ARM64: KVM: Emulate PSCI v0.2 CPU_SUSPEND ARM/ARM64: KVM: Advertise KVM_CAP_ARM_PSCI_0_2 to user space Documentation/virtual/kvm/api.txt | 17 +++ arch/arm/include/asm/kvm_host.h | 2 +- arch/arm/include/asm/kvm_psci.h | 6 +- arch/arm/include/uapi/asm/kvm.h | 10 +- arch/arm/kvm/arm.c | 1 + arch/arm/kvm/handle_exit.c | 10 +- arch/arm/kvm/psci.c | 235 ++++++++++++++++++++++++++++++++++--- arch/arm64/include/asm/kvm_host.h | 2 +- arch/arm64/include/asm/kvm_psci.h | 6 +- arch/arm64/include/uapi/asm/kvm.h | 10 +- arch/arm64/kvm/handle_exit.c | 10 +- include/uapi/linux/Kbuild | 1 + include/uapi/linux/kvm.h | 9 ++ include/uapi/linux/psci.h | 90 ++++++++++++++ 14 files changed, 372 insertions(+), 37 deletions(-) create mode 100644 include/uapi/linux/psci.h -- 1.7.9.5
