(Arnaldo Carvalho de Melo) . Fix --delay option in 'stat' man page (Andi Kleen) . Use the DWARF unwind info only if loaded (Jean Pihet): Developer stuff: . Improve forked workload error reporting by sending the errno in the signal data queueing integer field, using sigqueue and by doing the signal setup in the evlist methods, removing open coded equivalents in various tools. (Arnaldo Carvalho de Melo) . Do more auto exit cleanup shores in the 'evlist' destructor, so that the tools don't have to all do that sequence. (Arnaldo Carvalho de Melo) .

[PATCH] ARM: OMAP4: sleep/smp: switch CPU to BE if compiled for BE

by Taras Kondratiuk

From: Victor Kamensky <victor.kamensky(a)linaro.org> If kernel operates in BE mode on device that has LE bootloader/ROM code, we need to switch CPU to operate in BE mode before it will start to access BE data. Generic secondary_startup function that is called from OMAP specific secondary startup code will do the switch, but we need to do it earlier because OMAP's secondary_startup code works with BE data.

[PATCH V2 0/8] sched: cleanup trigger_load_balance

by Daniel Lezcano

This patchset does a cleanup on the parameters passed from the function 'trigger_load_balance' to the underneath functions. The cpu is passed as parameter to the different functions as well as the struct rq but this one contains already the cpu information. Moreover, in the call stack for these functions, we have the struct rq retrieved from the cpu, and then the cpu retrieve from the struct rq, etc ... The patchset unifies all these functions to have a struct rq parameter and removes the pointless parameters. -static inline int find_new_ilb(int call_cpu) +static inline int find_new_ilb(void) -static void nohz_balancer_kick(int cpu) +static void nohz_balancer_kick(void) -static void rebalance_domains(int cpu, enum cpu_idle_type idle) +static void rebalance_domains(struct rq *rq, enum cpu_idle_type idle) -static void nohz_idle_balance(int this_cpu, enum cpu_idle_type idle) +static void nohz_idle_balance(struct rq *this_rq, enum cpu_idle_type idle) -static inline int nohz_kick_needed(struct rq *rq, int cpu) +static inline int nohz_kick_needed(struct rq *rq) -static inline int on_null_domain(int cpu) +static inline int on_null_domain(struct rq *rq) Changelog: V2: - added missing patch 1/8 - added acked-by from Preeti U Murthy for patch 4 and 5 Daniel Lezcano (8): sched: reduce trigger_load_balance parameters sched: reduce nohz_kick_needed parameters sched: pass struct rq to on_null_domain function sched: remove unused parameter for find_new_ilb sched: remove unused parameter in nohz_balancer_kick function sched: pass struct rq to rebalance_domains function sched: pass struct rq to nohz_idle_balance function sched: factor out on_null_domain check in trigger_load_balance function kernel/sched/core.c | 2 +- kernel/sched/fair.c | 45 +++++++++++++++++++++++---------------------- kernel/sched/sched.h | 2 +- 3 files changed, 25 insertions(+), 24 deletions(-) -- 1.7.9.5

Without this patch, I can't get serial console to come up on Exynos platforms when amba-pl011 driver enabled. But Greg is particularly not at all happy with this patch. Any comments with respect to fixing this issue would be highly appreciated. Attaching the complete patch for reference. -- Tushar Behera

[PATCH v2 0/5] ARM: kprobes: big endian support

by Taras Kondratiuk

Reworked initial Ben's series for big endian support [1]. Dropped patches that are not directly related to kprobes. Current set of patches is enough to have functional BE kprobes. One ARM kprobe test fails on Cortex-A15 boards (TC2 and Keystone2 EVM), while it passes on Pandaboard. The issue is not related to this series and already present in v3.13-rc7. I'll try to look into it later. v1..v2: Fixed coprocessor instruction building for ARM tests in the patch "ARM: kprobes-test: use <asm/opcodes.h> for ARM instruction building" Based on v3.13-rc7. [1] http://www.spinics.net/lists/arm-kernel/msg285210.html Ben Dooks (4): ARM: kprobes: fix instruction fetch order with <asm/opcodes.h> ARM: kprobes-test: use <asm/opcodes.h> for instruction accesses ARM: kprobes-test: use <asm/opcodes.h> for ARM instruction building ARM: kprobes-test: use <asm/opcodes.h> for Thumb instruction building Taras Kondratiuk (1): ARM: kprobes-test: Workaround GAS .align bug arch/arm/kernel/kprobes-common.c | 19 +- arch/arm/kernel/kprobes-test-arm.c | 603 +++++++++++++++++----------------- arch/arm/kernel/kprobes-test-thumb.c | 447 ++++++++++++------------- arch/arm/kernel/kprobes-test.c | 13 +- arch/arm/kernel/kprobes-test.h | 2 +- arch/arm/kernel/kprobes-thumb.c | 20 +- arch/arm/kernel/kprobes.c | 9 +- 7 files changed, 562 insertions(+), 551 deletions(-) -- 1.7.9.5

[PATCH] spi: Use bitfields for multiple data lines

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Trent Piepho observed that since the current realistic maximum number of data lines is four we can pack the spi_transfer struct more efficiently if we use a bitfield for the number of bits, allowing the fields to fit in a single byte along with cs_change. If space becomes an issue further optimiation is possible by only using the constants and packing the values chosen for them.

[PATCH v5 0/5] Hardware Reduced Mode Cleanup for ACPI

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> This series of patches starts with Hanjun's patch to create a kernel config item for CONFIG_ACPI_REDUCED_HARDWARE [0]. Building on that, I then reviewed all of the code that touched any of several fields in the FADT that the OSPM is supposed to ignore when ACPI is in Hardware Reduced mode [1]. Any time there was a use of one of the fields to be ignored, I evaluated whether or not the code was implementing Hardware Reduced mode correctly. Similarly, for each the flags in the FADT flags field that are to be ignored in Hardware Reduced mode, the kernel code was again scanned for proper usage. The remainder of the patches are to fix all of the situations I could find where the kernel would not behave correctly in this ACPI mode. These seem to work just fine on the RTSM model for ARMv7, both with and without ACPI enabled, and with and without ACPI_REDUCED_HARDWARE enabled; similarly for the FVP model for ARMv8. The patches for ACPI on ARM hardware have been submitted elsewhere but they presume that reduced HW mode is functioning correctly. In the meantime, there's no way I can think of to test all possible scenarios so feedback would be greatly appreciated. [0] List at https://wiki.linaro.org/LEG/Engineering/Kernel/ACPI/AcpiReducedHw#Section_5… [1] Please see the ACPI Specification v5.0 for details on Hardware Reduced mode (sections 3.11.1, 4.1, 5.2.9, at a minimum). Changes for v5: -- Clarify that if the kernel config option to build ACPI hardware reduced mode is used, it builds a hardware reduced *only* kernel (i.e., full legacy ACPI mode will no longer work). Changes for v4: -- Given the current state of ACPICA, disable CONFIG_ACPI_REDUCED_HARDWARE for use on anything other than ARM. -- Replaced #ifdefs with run-time checking for hardware reduced mode, whenever possible Changes for v3: -- Modified enabling ACPI_REDUCED_HARDWARE in ACPICA when using kernel config item CONFIG_ACPI_REDUCED_HARDWARE; now consistent with ACPICA code base where needed -- Enable X86 for CONFIG_ACPI_REDUCED_HARDWARE -- Minimize bus master reload patching -- Remove unneeded patch for dmi_check_system() (was 4/6) -- Correct the patch for removing unneeded map/unmap of FADT fields Changes for v2: -- Remove patch that was outside of reduced HW mode changes -- Simplify CONFIG_ACPI_REDUCED_HARDWARE in Kconfig -- Simplify use of CONFIG_ACPI_REDUCED_HARDWARE in #ifdefs -- Ensure changelogs are present -- Combine and simplify previous patches 8 & 10 Al Stone (5): ACPI: introduce CONFIG_ACPI_REDUCED_HARDWARE_ONLY to enforce this ACPI mode ACPI: bus master reload not supported in reduced HW mode ACPI: HW reduced mode does not allow use of the FADT sci_interrupt field ACPI: in HW reduced mode, using FADT PM information is not allowed.

[PATCH 0/5] ARM: kprobes: big endian support

by Taras Kondratiuk

Reworked initial Ben's series for big endian support [1]. Dropped patches that are not directly related to kprobes. Current set of patches is enough to have functional BE kprobes. All kprobes-tests pass in any LE/BE and ARM/Thumb combination. Based on v3.13-rc5.

[PATCH v3 0/2] PSCI system off and reset for KVM ARM/ARM64

by Anup Patel

The Power State and Coordination Interface (PSCI) specification defines SYSTEM_OFF and SYSTEM_RESET functions for system poweroff and reboot. This patchset adds emulation of PSCI SYSTEM_OFF and SYSTEM_RESET functions in KVM ARM/ARM64 by forwarding them to user space (QEMU or KVMTOOL) using KVM_EXIT_SYSTEM_EVENT exit reason. To try this patch from guest kernel, we will need PSCI-based restart and poweroff support in the guest kenel for both ARM and ARM64. Rob Herring has already submitted patches for PSCI-based restart and poweroff in ARM kernel but these are not merged yet due unstable device tree bindings of kernel PSCI support. We will be having similar patches for PSCI-based restart and poweroff in ARM64 kernel. (Refer http://www.spinics.net/lists/arm-kernel/msg262217.html) (Refer http://www.spinics.net/lists/devicetree/msg05348.html) Change Log: V3: - Simplify handle_hvc() for both ARM and ARM64 - Minor fix in comments for kvm_psci_call() V2: - Replace KVM_EXIT_RESET with KVM_EXIT_SYSTEM_EVENT - Make kvm_psci_call() return convention to match KVM ARM return convention V1: - Initial revised patch after RFC PATCH.

[PATCH 1/2] ARM: SA1100: Create dummy clk_get_rate() to avoid build failures

by Viresh Kumar

There are some parts of common kernel which would be using routines like clk_get_rate() on some platforms. Currently these wouldn't be called for SA1100 boards but we need these routines for successful builds of these boards. So, this patch creates a dummy clk_get_rate() routine which is being used by cpufreq core. More dummy routines might be added later if there is a need for that.

[PATCH] video: amba-clcd: Make CLCD driver available on more platforms

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The CLCD driver is used on ARM reference models for ARMv8 so add ARM64 to the list of dependencies. The driver also has no build time dependencies on ARM (stubs are provided for ARM-specific DMA functions in the code) so make it available with COMPILE_TEST in order to maximise build coverage.

[PATCH] ARM: traps: fix opcode endianness when read from user memory

Currently code has an inverted logic: opcode from user memory is swapped to a proper endianness only in case of read error.

[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.

[PATCH V3 Resend] cpufreq: create cpufreq_generic_get() routine

by Viresh Kumar

CPUFreq drivers that use clock frameworks interface,i.e. clk_get_rate(), to get CPUs clk rate, has similar sort of code used for most of them. This patch adds a generic ->get() which will do the same thing for them. All those drivers are required to now is to set .get to cpufreq_generic_get() and set their clk pointer in policy->clk during ->init().

[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.

kexec/kdump for arm64

by Geoff Levand

Hi All, Just for anyone who might be interested, I've started to do some work on kexec and kdump support for arm64. This work is being done within Linaro, so is tracked by their Jira system: https://cards.linaro.org/browse/CARD-563 I have these two git repos with my work-in-progress patches: https://git.linaro.org/gitweb?p=people/geoff/kexec-tools.git https://git.linaro.org/gitweb?p=people/geoff/linux-kexec.git As of now, I'm just trying to get the pieces in place for a basic kexec reboot. Kdump and advanced features will come later. Comments or suggestions welcome. -Geoff

[PATCH CFT] ARM:EP93XX: Enable ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR by default

by panchaxari

This patch enables ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR as default configs to EP93XX platforms from Cirrus. Introduction of PHYS_VIRT config as default config enables phy-to-virt and virt-to-phy translation functions at boot and module loading time, and enforce dynamic reallocation of memory. PHYS_VIRT config is mutually exclusive to XIP_KERNEL, XIP_KERNEL is used in systems with NOR flash devices. AUTO_ZRELADDR config enables auto calculation of the decompressed kernel image address. AUTO_ZRELADDR config is mutually exclusive to ZBOOT_ROM, and also assumes zImage to be loaded in the first 128MiB from start of memory.

[PATCH] ASoC: da9055: Partially fix device registration

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> It has never been possible to even load the da9055 driver since both the MFD and CODEC drivers register the I2C device "da9055". Fix this by using the usual pattern for MFDs with multiple I2C addresses and having the CODEC driver reference an I2C dummy registered by the MFD. Since I don't know which I2C address to use for the CODEC a FIXME has been left in the MFD, this doesn't make anything any worse since the device has never been able to load in the first place.

[RFC][PATCH v5 00/14] sched: packing tasks

by Vincent Guittot

This is the 5th version of the previously named "packing small tasks" patchset. "small" has been removed because the patchset doesn't only target small tasks anymore. This patchset takes advantage of the new per-task load tracking that is available in the scheduler to pack the tasks in a minimum number of CPU/Cluster/Core. The packing mechanism takes into account the power gating topology of the CPUs to minimize the number of power domains that need to be powered on simultaneously. Most of the code has been put in fair.c file but it can be easily moved to another location. This patchset tries to solve one part of the larger energy-efficient scheduling problem and it should be merged with other proposals that solve other parts like the power-scheduler made by Morten. The packing is done in 3 steps: The 1st step creates a topology of the power gating of the CPUs that will help the scheduler to choose which CPUs will handle the current activity. This topology is described thanks to a new flag SD_SHARE_POWERDOMAIN that indicates whether the groups of CPUs of a scheduling domain share their power state. In order to be efficient, a group of CPUs that share their power state will be used (or not) simultaneously. By default, this flag is set in all sched_domain in order to keep the current behavior of the scheduler unchanged. The 2nd step evaluates the current activity of the system and creates a list of CPUs for handling it. The average activity level of CPUs is set to 80% but is configurable by changing the sched_packing_level knob. The activity level and the involvement of a CPU in the packing effort is evaluated during the periodic load balance similarly to cpu_power. Then, the default load balancing behavior is used to balance tasks between this reduced list of CPUs. As the current activity doesn't take into account a new task, an unused CPUs can also be selected during the 1st wake up and until the activity is updated. The 3rd step occurs when the scheduler selects a target CPU for a newly awakened task. The current wakeup latency of idle CPUs is used to select the one with the most shallow c-state. In some situation where the task load is small compared to the latency, the newly awakened task can even stay on the current CPU. Since the load is the main metric for the scheduler, the wakeup latency is transposed into an equivalent load so that the current mechanism of the load balance that is based on load comparison, is kept unchanged. A shared structure has been created to exchange information between scheduler and cpuidle (or any other framework that needs to share information). The wakeup latency is the only field for the moment but it could be extended with additional useful information like the target load or the expected sleep duration of a CPU. The patchset is based on v3.12-rc2 and is available in the git tree: git://git.linaro.org/people/vingu/kernel.git branch sched-packing-small-tasks-v5 If you want to test the patchset, you must enable CONFIG_PACKING_TASKS first. Then, you also need to create a arch_sd_local_flags that will clear the SD_SHARE_POWERDOMAIN flag at the appropriate level for your architecture. This has already be done for ARM architecture in the patchset. The figures below show the latency of cyclictest with and without the patchset on an ARM platform with a v3.11. The test has been runned 10 times on each kernel. #cyclictest -t 3 -q -e 1000000 -l 3000 -i 1800 -d 100 average (us) stdev v3.11 381,5 79,86 v3.11 + patches 173,83 13,62 Change since V4: - v4 posting:https://lkml.org/lkml/2013/4/25/396 - Keep only the aggressive packing mode. - Add a finer grain power domain description mechanism that includes DT description - Add a structure to share information with other framework - Use current wakeup latency of an idle CPU when selecting the target idle CPU - All the task packing mechanism can be disabled with a single config option Change since V3: - v3 posting: https://lkml.org/lkml/2013/3/22/183 - Take into account comments on previous version. - Add an aggressive packing mode and a knob to select between the various mode Change since V2: - v2 posting: https://lkml.org/lkml/2012/12/12/164 - Migrate only a task that wakes up - Change the light tasks threshold to 20% - Change the loaded CPU threshold to not pull tasks if the current number of running tasks is null but the load average is already greater than 50% - Fix the algorithm for selecting the buddy CPU.
