[RFC PATCH v3] ARM: uprobes need icache flush after xol write

by Victor Kamensky

Hi, As it was discussed on [1] today, here is potential ARM specific fix for uprobes dcache/icache flush problem. I am aware that other options are still under discussion. This patch is provided for reference only as one of possible solutions. The xol slot flush code shares code with ARM backend of copy_to_user_page - flush_ptrace_access function. But code and new implementation of flush_uprobe_xol_access modified in such way that xol flush does need vma. Changes since V2 [2] version: x) address Dave Long's comment about passing checkpatch x) addressed Oleg's comment and instead of arch_uprobe_flush_xol_access function use arch_uprobe_copy_ixol function that maps kernel pages, copies, and flush caches x) removed FLAG_UA_BROADCAST, during discussion on [1] it was elaborated that task executing xol single step could be migrated to another CPU, so we need to take care of remote icaches if CPU does not support remote snooping. I.e flush_uprobe_xol_access will check cache_ops_need_broadcast() and perform smp_call_function on SMP CPUs that do not support remote snooping. x) added preempt_disable/preempt_enable in arch_uprobe_copy_ixol as copy_to_user_page does. I admit that I have some guesses, but I don't completely understand why copy_to_user_page does that, so playing on safe side - added it similar to copy_to_user_page code. Thanks, Victor [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/247611.html [2] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/245743.html Victor Kamensky (1): ARM: uprobes need icache flush after xol write arch/arm/include/asm/cacheflush.h | 2 ++ arch/arm/kernel/uprobes.c | 22 ++++++++++++++++++++++ arch/arm/mm/flush.c | 33 ++++++++++++++++++++++++++++----- include/linux/uprobes.h | 3 +++ kernel/events/uprobes.c | 25 +++++++++++++++++-------- 5 files changed, 72 insertions(+), 13 deletions(-) -- 1.8.1.4

[PATCH V1 Resend] hrtimer: call switch_hrtimer_base() after setting new expiry time

by Viresh Kumar

In switch_hrtimer_base() we are calling hrtimer_check_target() which guarantees this: /* * With HIGHRES=y we do not migrate the timer when it is expiring * before the next event on the target cpu because we cannot reprogram * the target cpu hardware and we would cause it to fire late. * * Called with cpu_base->lock of target cpu held. */ But switch_hrtimer_base() is only called from one place, i.e. __hrtimer_start_range_ns() and at that point (where we call switch_hrtimer_base()) expiration time is not yet known as we call this routine later: hrtimer_set_expires_range_ns(). To fix this, we need to find the updated expiry time before calling switch_hrtimer_base(). Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- Hi Thomas, I have sent this previously as part of: https://lkml.org/lkml/2014/4/4/23 But as you asked to send bugfixes without any dependencies for ticks patches, I thought of sending bugfixes separately for timers too. This was the only bugfix from that series and other patches don't conflict with it, so I am not resending other patches from above series again.

[RFC 0/4] sched: consolidation of cpu_power

by Vincent Guittot

Part of this patchset was previously part of the larger tasks packing patchset [1]. I have splitted the latter in 3 different patchsets (at least) to make the thing easier. -configuration of sched_domain topology [2] -update and consolidation of cpu_power (this patchset) -tasks packing algorithm SMT system is no more the only system that can have a CPUs with capacity that is different from the default value. We need to extend the use of cpu_power_orig to all kind of platform so the scheduler will have both the maximum capacity (cpu_power_orig/power_orig) and the current capacity (cpu_power/power) of CPUs and groups of the sched_domains. During load balance, the scheduler evaluates the number of tasks that a group of CPUs can handle. The current method ensures that we will not return more capacity than number of real cores but it returns wrong value for group of LITTLE cores and in some situation for SMT system. The proposed solution computes the ratio between CPUs and cores for a group durint the init sequence and uses it with power and power_orig to return the current capacity of a group.

[PATCH v9 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: 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 | 19 ++-- arch/arm/kvm/arm.c | 1 + arch/arm/kvm/handle_exit.c | 10 +- arch/arm/kvm/psci.c | 222 +++++++++++++++++++++++++++++++++---- arch/arm64/include/asm/kvm_host.h | 2 +- arch/arm64/include/asm/kvm_psci.h | 6 +- arch/arm64/include/uapi/asm/kvm.h | 21 ++-- arch/arm64/kvm/handle_exit.c | 10 +- include/uapi/linux/Kbuild | 1 + include/uapi/linux/kvm.h | 9 ++ include/uapi/linux/psci.h | 78 +++++++++++++ 14 files changed, 356 insertions(+), 48 deletions(-) create mode 100644 include/uapi/linux/psci.h -- 1.7.9.5
