[PATCH] cpufreq: report driver's successful {un}registration

by Viresh Kumar

We do report driver's successful {un}registration from cpufreq core, but is done with pr_debug() and so this doesn't appear in boot logs. Convert this to pr_info() to make it visible in logs.

[RESEND PATCH] arm64: topology: add MPIDR-based detection

by Zi Shen Lim

Lorenzo and Mark agreed on the following updated patch from Lorenzo: http://www.spinics.net/lists/arm-kernel/msg336998.html W.r.t. cluster numbering, we're now back to where we were with the the original patch sent out in April: https://lkml.org/lkml/2014/4/22/951 Were there any other objections to this approach? AFAICT, this patch should be good to go for 3.16. ------->8-------- Create cpu topology based on MPIDR. When hardware sets MPIDR to sane values, this method will always work. Therefore it should also work well as the fallback method. [1] When we have multiple processing elements in the system, we create the cpu topology by mapping each affinity level (from lowest to highest) to threads (if they exist), cores, and clusters.

[Bug] Spurious hrtimer-interrupts

by Viresh Kumar

Hi Thomas/Daniel et al, This isn't about the problem I reported earlier, where you advised to add ONESHOT_STOPPED mode: https://lkml.org/lkml/2014/5/9/508. Above problem was about stopping the clock-event device when its not used anymore. This ($subject) problem was initially spotted on Ivybrdge V2, 12 core X86 server by Santosh. And then I reproduced it on Dual core ARM Exynos (isn't that frequent as it was on x86 though). Problem: Getting spurious ticks where hrtimer_interrupt() returns without servicing any hrtimers. Kernel hack to catch this: http://pastebin.com/bTM7nqDc (Over 3.16-rc3) X86 boot logs: http://pastebin.com/E6axDnsa (search: hrtimer_interrupt) /proc/cpuinfo: http://pastebin.com/uQx9TmsA The last I could debug it to is: - Clockevent device is programmed for time 'x' seconds (Verified this by storing next-event from within lapic_next_event()). - Tick fires ~300 us before 'x' - Traversing through the list of hrtimers doesn't result in any pending hrtimer and we simply return. And so *spurious* interrupt. - Happens when ticks are active or stopped (search for "tick-stopped" in logs) Driver monitored for x86: arch/x86/kernel/apic/apic.c Similar behavior observed on exynos with arm_arch_timer.c I couldn't get any deeper into it to see what's going on. From the behavior It looks lik the calculations we are doing with dev->mult/shift gives timeout <= next-event, whereas it should be >= ? Not at all sure though. Reported-by: Santosh Shukla <santosh.shukla(a)linaro.org> Note: Even the Hacky patchset that tried to to disable clockevent device when not used anymore, isn't able to fix it: https://lkml.org/lkml/2014/5/9/99.. -- viresh

[PATCH v8 0/2] 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 Will Deacon's tree. Changes v7 to v8: * Fix bug where el1_irq was calling ct_user_exit rather than el0_irq Changes v6 to v7: * Rename parameter of ct_user_exit from restore to syscall Changes v5 to v6: * Don't save far_el1 in x26 in el0_dbg path (not needed) * TIF_NOHZ processes go through the slow path (so no register save/restore is needed in ct_user_enter) Changes v4 to v5: * Improvement to code restoring far_el1 (suggested by Christopher Covington) * Improvement to register save/restore in ct_user_enter Changes v3 to v4: * Rename parameter of ct_user_exit from save to restore * Rebased patch to Will Deacon's tree (branch remotes/origin/aarch64 of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git) Changes v2 to v3: * Save/restore necessary registers in ct_user_enter and ct_user_exit * Annotate "error paths" out of el0_sync with ct_user_exit Changes v1 to v2: * Save far_el1 in x26 temporarily Larry Bassel (2): arm64: adjust el0_sync so that a function can be called arm64: enable context tracking arch/arm64/Kconfig | 1 + arch/arm64/include/asm/thread_info.h | 4 +++ arch/arm64/kernel/entry.S | 58 +++++++++++++++++++++++++++++++----- 3 files changed, 56 insertions(+), 7 deletions(-) -- 1.8.3.2

[RESEND PATCH v4 0/2] arm64: Add seccomp support

by AKASHI Takahiro

(I don't think that discussions below about ptrace() have impact on this patchset. http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/268923.html ) (Please apply this patch after my audit patch in order to avoid some conflict on arm64/Kconfig.) This patch enables secure computing (system call filtering) on arm64. System calls can be allowed or denied by loaded bpf-style rules. Architecture specific part is to run secure_computing() on syscall entry and check the result. See [2/2] This code is tested on ARMv8 fast model using libseccomp v2.1.1 with modifications for arm64 and verified by its "live" tests, 20, 21 and 24. Changes v3 -> v4: * removed the following patch and moved it to "arm64: prerequisites for audit and ftrace" patchset since it is required for audit and ftrace in case of !COMPAT, too. "arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h" Changes v2 -> v3: * removed unnecessary 'type cast' operations [2/3] * check for a return value (-1) of secure_computing() explicitly [2/3] * aligned with the patch, "arm64: split syscall_trace() into separate functions for enter/exit" [2/3] * changed default of CONFIG_SECCOMP to n [2/3] Changes v1 -> v2: * added generic seccomp.h for arm64 to utilize it [1,2/3] * changed syscall_trace() to return more meaningful value (-EPERM) on seccomp failure case [2/3] * aligned with the change in "arm64: make a single hook to syscall_trace() for all syscall features" v2 [2/3] * removed is_compat_task() definition from compat.h [3/3] AKASHI Takahiro (2): asm-generic: Add generic seccomp.h for secure computing mode 1 arm64: Add seccomp support arch/arm64/Kconfig | 14 ++++++++++++++ arch/arm64/include/asm/seccomp.h | 25 +++++++++++++++++++++++++ arch/arm64/include/asm/unistd.h | 3 +++ arch/arm64/kernel/entry.S | 4 ++++ arch/arm64/kernel/ptrace.c | 6 ++++++ include/asm-generic/seccomp.h | 28 ++++++++++++++++++++++++++++ 6 files changed, 80 insertions(+) create mode 100644 arch/arm64/include/asm/seccomp.h create mode 100644 include/asm-generic/seccomp.h -- 1.7.9.5
