[PATCH] cpufreq: remove sysfs files for CPU which failed to come back after resume

by Viresh Kumar

There are cases where cpufreq_add_dev() may fail for some CPUs during resume. With the current code we will still have sysfs cpufreq files for such CPUs, and struct cpufreq_policy would be already freed for them. Hence any operation on those sysfs files would result in kernel warnings. To fix this, lets remove those sysfs files or put the associated kobject in case of such errors. Also, to make it simple lets remove the sysfs links from all the CPUs (except policy->cpu) during suspend as that operation wouldn't result with a loss of sysfs file permissions. And so we will create those links during resume as well.

[PATCH v5 0/4] AArch64: KGDB support

by vijay.kilari＠gmail.com

From: Vijaya Kumar K <Vijaya.Kumar(a)caviumnetworks.com> Based on the step-handler and break-handler hooks patch from Sandeepa (Patch 1), KGDB debugging support is added for EL1 debug in AArch64 mode. Any updates that come for Patch 1 from Sandeepa will be rebased in next version With second patch,register layout is updated to be inline with GDB tool. Basic GDB connection, break point set/clear and info commands are supported except step/next debugging With third patch, step/next debugging support is added, where in pc is updated to point to the instruction to be stepped and stopped. With fourth patch, the compile time breakpoint instruction reordering is fixed by making kgbd_breakpoint() as noinline Tested with ARM64 simulator v5: - Updated BRK #imm16 value to 0x400 & 0x401 as per recommendation as per Marcus recommendataion http://patchwork.ozlabs.org/patch/290801/ - Rebased to 3.13 AArch64 kernel v4: - Updated kgdb_single_step and kgdb_cpu_doing_single_step variables properly based on gdb state v3: - Rebased to v4 version of Sandeepa Prabhu's patch (patch 1) - Made dynamic break point instruction encoding generic - Made ESR value encoding generic for dynamic and compile break point - Used memcpy and memset to copy register contents to gdb buffer - Fixed reordering of break point instruction by compiler with patch 3 - Rebased against AAach64 upstream kernel v2: - Moved break instruction encoding to debug-monitors.h file - Fixed endianess of compile break instruction encoding - Updated I/O buffer sizes - Updated register buffer size - Remove changes to debug_exception handler in entry.S for - ELR update and step debugging with update pc instead of ELR - Rebased against AArch64 upstream kernel v1: - Initial patch-set Sandeepa Prabhu (1): arm64: support single-step and breakpoint handler hooks Vijaya Kumar K (3): AArch64: KGDB: Add Basic KGDB support AArch64: KGDB: Add step debugging support KGDB: make kgdb_breakpoint() as noinline arch/arm64/include/asm/debug-monitors.h | 68 +++++++ arch/arm64/include/asm/kgdb.h | 86 ++++++++ arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/debug-monitors.c | 86 +++++++- arch/arm64/kernel/entry.S | 2 + arch/arm64/kernel/kgdb.c | 338 +++++++++++++++++++++++++++++++ kernel/debug/debug_core.c | 2 +- 7 files changed, 581 insertions(+), 2 deletions(-) create mode 100644 arch/arm64/include/asm/kgdb.h create mode 100644 arch/arm64/kernel/kgdb.c -- 1.7.9.5

[PATCH 1/4] arm64: topology: Implement basic CPU topology support

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Add basic CPU topology support to arm64, based on the existing pre-v8 code and some work done by Mark Hambleton. This patch does not implement any topology discovery support since that should be based on information from firmware, it merely implements the scaffolding for integration of topology support in the architecture. The goal is to separate the architecture hookup for providing topology information from the DT parsing in order to ease review and avoid blocking the architecture code (which will be built on by other work) with the DT code review by providing something something simple and basic. A following patch will implement support for parsing the DT topology bindings for ARM, similar patches will be needed for ACPI.

[RFC PATCH] KVM: arm/arm64: Clarify KVM_ARM_VCPU_INIT api

by Christoffer Dall

There is nothing technically or semantically wrong with calling KVM_ARM_VCPU_INIT more than once, and even calling this on a VCPU after the VCPU has been executed. It just happens that user space will need a way to reset the VCPU or put the VCPU back in PSCI power-off mode after the VM has run, for example when driving a system reset from user space.

[PATCH 1/3] ARM64: perf: add support for perf registers API

by jean.pihet＠linaro.org

From: Jean Pihet <jean.pihet(a)linaro.org> This patch implements the functions required for the perf registers API, allowing the perf tool to interface kernel register dumps with libunwind in order to provide userspace backtracing. Compat mode is also supported. Only the general purpose user space registers are exported, i.e.: PERF_REG_ARM_X0, ... PERF_REG_ARM_X28, PERF_REG_ARM_FP, PERF_REG_ARM_LR, PERF_REG_ARM_SP, PERF_REG_ARM_PC and not the PERF_REG_ARM_V* registers.

[PATCH 00/10] Support VGIC save/restore using device control API

by Christoffer Dall

Implement save/restore of the VGIC state using the newer KVM Device Control API. This requries some number of changes to existing code in addition to actually supporting save/restore of the necessary state. The first patches (01-03) support creating the VGIC using the Device Control API. This change is necessary because there are no other suitable KVM APIs that we can leverage to access the VGIC state from user space and the device control API was crafted exactly for this purpose. Subsequent patches add the missing infrastructure and user space API pieces necessary to actually save and restore the VGIC state. The GIC v2.0 architecture specification already specifies registers that can be used to save and restore the complete VGIC state for suspend/resume purposes on real hardware, and we can reuse this interface for the VGIC. The API is therefore based on the memory-mapped register accesses defined in the specs. See the individual patches for details. The patches are based on kvm-arm-next with the arch timers save/restore patches applied: git://git.linaro.org/people/cdall/linux-kvm-arm.git timer-migrate-v4 This patch series based on the above can be cloned from: git://git.linaro.org/people/cdall/linux-kvm-arm.git vgic-migrate-v4 User space patches for QEMU have also been posted on the list, but an updated version is underway. Tested on Versatile Express TC2. Changelogs in the individual patches.

[PATCH 3/3] ARM64: perf: add support for frame pointer unwinding in compat mode

From: Jean Pihet <jean.pihet(a)linaro.org> When profiling a 32-bit application, user space callchain unwinding using the frame pointer is performed in compat mode.

[PATCH RESEND] arm64: KVM: Add Kconfig option for max VCPUs per-Guest

by Anup Patel

Current max VCPUs per-Guest is set to 4 which is preventing us from creating a Guest (or VM) with 8 VCPUs on Host (e.g. X-Gene Storm SOC) with 8 Host CPUs. The correct value of max VCPUs per-Guest should be same as the max CPUs supported by GICv2 which is 8 but, increasing value of max VCPUs per-Guest can make things slower hence we add Kconfig option to let KVM users select appropriate max VCPUs per-Guest.
