[PATCH RFC v2 0/6] ARM64: Add kernel probes(Kprobes) support

by Sandeepa Prabhu

This patchset adds support for kernel probes(kprobes), jump probes(jprobes) and return probes(kretprobes) support for ARM64. Kprobes mechanism make use of software breakpoint and single stepping support available in ARM v8 kernel. This patchset make use of (and dependant upon) dynamic kernel patching feature published in patch series: https://lkml.org/lkml/2013/10/15/891 changes: v1 -> v2 1. Implemented review comments on v1 2. Debug montior hooks implementation is changed to use rwlocks instead of rcu and spinlock. 3. Enabled recursing in kprobes handler for kprobes re-enter support. 4. Re-split the patchset to seperate single-stepping, simulation and kretprobes features. 5. instruction simulation is made independent of 'struct kprobes' 6. Added 'Linaro Copyright' statements in new added files. 7. Used arm64 instead of aarch64 in file names and comments. Tested on ARM v8 fast model with sample modules from: samples/kprobes/ Sandeepa Prabhu (6): arm64: support single-step and breakpoint handler hooks arm64: Kprobes with single stepping support arm64: Kprobes instruction simulation support arm64: Add kernel return probes support(kretprobes) arm64: Enable kprobes support for arm64 platform kprobes: Add cases for arm and arm64 in sample module arch/arm64/Kconfig | 2 + arch/arm64/configs/defconfig | 20 +- arch/arm64/include/asm/debug-monitors.h | 21 + arch/arm64/include/asm/kprobes.h | 60 +++ arch/arm64/include/asm/probes.h | 50 +++ arch/arm64/include/asm/ptrace.h | 6 + arch/arm64/kernel/Makefile | 2 + arch/arm64/kernel/condn-helpers.c | 120 ++++++ arch/arm64/kernel/debug-monitors.c | 86 +++- arch/arm64/kernel/entry.S | 2 + arch/arm64/kernel/kprobes-arm64.c | 313 +++++++++++++++ arch/arm64/kernel/kprobes-arm64.h | 30 ++ arch/arm64/kernel/kprobes.c | 682 ++++++++++++++++++++++++++++++++ arch/arm64/kernel/kprobes.h | 30 ++ arch/arm64/kernel/probes-decode.h | 110 ++++++ arch/arm64/kernel/simulate-insn.c | 184 +++++++++ arch/arm64/kernel/simulate-insn.h | 33 ++ arch/arm64/kernel/vmlinux.lds.S | 1 + samples/kprobes/kprobe_example.c | 16 + 19 files changed, 1756 insertions(+), 12 deletions(-) create mode 100644 arch/arm64/include/asm/kprobes.h create mode 100644 arch/arm64/include/asm/probes.h create mode 100644 arch/arm64/kernel/condn-helpers.c create mode 100644 arch/arm64/kernel/kprobes-arm64.c create mode 100644 arch/arm64/kernel/kprobes-arm64.h create mode 100644 arch/arm64/kernel/kprobes.c create mode 100644 arch/arm64/kernel/kprobes.h create mode 100644 arch/arm64/kernel/probes-decode.h create mode 100644 arch/arm64/kernel/simulate-insn.c create mode 100644 arch/arm64/kernel/simulate-insn.h -- 1.8.1.2

[PATCH v2 0/2] perf: config: add per-feature check flags

by Jean Pihet

Add CFLAGS and LDFLAGS for each feature to be checked during the build. This allows to pass particular flags and parameters to the feature checks compilation. Use the per-feature check flags for the unwinding feature in order to correctly compile the libunwind and libunwind-debug-frame feature checks. This change set simplifies the flags passing mechanism between the Makefiles in config/Makefile and config/feature-checks; this could be farther optimized by moving the compilation flags to the per-feature check flags for all features to be checked. Tested on x86_64, ARMv7 and ARMv8 with and without LIBUNWIND_DIR= set in 'make -C tools/perf' Jean Pihet (2): perf: add per-feature check flags perf: unwinding: use the per-feature check flags tools/perf/config/Makefile | 48 +++++++++++++++++-------------- tools/perf/config/feature-checks/Makefile | 6 ++-- 2 files changed, 29 insertions(+), 25 deletions(-) -- 1.7.11.7

[PATCH V5 1/2] cpufreq: Mark ARM drivers with CPUFREQ_NEED_INITIAL_FREQ_CHECK flag

by Viresh Kumar

Sometimes boot loaders set CPU frequency to a value outside of frequency table present with cpufreq core. In such cases CPU might be unstable if it has to run on that frequency for long duration of time and so its better to set it to a frequency which is specified in frequency table. On some systems we can't really say what frequency we're running at the moment and so for these we shouldn't check if we are running at a frequency present in frequency table. And so we really can't force this for all the cpufreq drivers. Hence we are created another flag here: CPUFREQ_NEED_INITIAL_FREQ_CHECK that will be marked by platforms which want to go for this check at boot time. Initially this is done for all ARM platforms but others may follow if required. Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- V4->V5: - Inverted flag, moved to CPUFREQ_NEED_INITIAL_FREQ_CHECK instead of CPUFREQ_SKIP_INITIAL_FREQ_CHECK and so this patch does it now for all the ARM drivers. -

[PATCH V4 1/2] cpufreq: Mark x86 drivers with CPUFREQ_SKIP_INITIAL_FREQ_CHECK flag

by Viresh Kumar

On some systems we can't really say what frequency we're running at the moment and so for these we shouldn't check if we are running at a frequency present in frequency table. For now mark all x86 drivers with this flag: CPUFREQ_SKIP_INITIAL_FREQ_CHECK. This patch also defines this macro. It will be used in cpufreq.c in the next patch. Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- V3->V4: - Reversed the order of patches - Moved definition of CPUFREQ_SKIP_INITIAL_FREQ_CHECK to patch 1/2 instead of 2/2. drivers/cpufreq/acpi-cpufreq.c | 1 + drivers/cpufreq/cpufreq-nforce2.c | 1 + drivers/cpufreq/e_powersaver.c | 1 + drivers/cpufreq/elanfreq.c | 1 + drivers/cpufreq/gx-suspmod.c | 1 + drivers/cpufreq/ia64-acpi-cpufreq.c | 1 + drivers/cpufreq/intel_pstate.c | 2 +- drivers/cpufreq/longhaul.c | 1 + drivers/cpufreq/longrun.c | 2 +- drivers/cpufreq/p4-clockmod.c | 1 + drivers/cpufreq/pcc-cpufreq.c | 2 +- drivers/cpufreq/powernow-k6.c | 1 + drivers/cpufreq/powernow-k7.c | 1 + drivers/cpufreq/powernow-k8.c | 3 ++- drivers/cpufreq/sc520_freq.c | 1 + drivers/cpufreq/speedstep-centrino.c | 1 + drivers/cpufreq/speedstep-ich.c | 1 + drivers/cpufreq/speedstep-smi.c | 1 + include/linux/cpufreq.h | 9 +++++++++ 19 files changed, 28 insertions(+), 4 deletions(-) diff --git a/drivers/cpufreq/acpi-cpufreq.c b/drivers/cpufreq/acpi-cpufreq.c index caf41eb..b8e4f79 100644 --- a/drivers/cpufreq/acpi-cpufreq.c +++ b/drivers/cpufreq/acpi-cpufreq.c @@ -903,6 +903,7 @@ static struct freq_attr *acpi_cpufreq_attr[] = { }; static struct cpufreq_driver acpi_cpufreq_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .verify = cpufreq_generic_frequency_table_verify, .target_index = acpi_cpufreq_target, .bios_limit = acpi_processor_get_bios_limit, diff --git a/drivers/cpufreq/cpufreq-nforce2.c b/drivers/cpufreq/cpufreq-nforce2.c index a05b876..b3222f6 100644 --- a/drivers/cpufreq/cpufreq-nforce2.c +++ b/drivers/cpufreq/cpufreq-nforce2.c @@ -370,6 +370,7 @@ static int nforce2_cpu_exit(struct cpufreq_policy *policy) } static struct cpufreq_driver nforce2_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .name = "nforce2", .verify = nforce2_verify, .target = nforce2_target, diff --git a/drivers/cpufreq/e_powersaver.c b/drivers/cpufreq/e_powersaver.c index 9012b8b..0826bda 100644 --- a/drivers/cpufreq/e_powersaver.c +++ b/drivers/cpufreq/e_powersaver.c @@ -389,6 +389,7 @@ static int eps_cpu_exit(struct cpufreq_policy *policy) } static struct cpufreq_driver eps_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .verify = cpufreq_generic_frequency_table_verify, .target_index = eps_target, .init = eps_cpu_init, diff --git a/drivers/cpufreq/elanfreq.c b/drivers/cpufreq/elanfreq.c index de08acf..426d14d 100644 --- a/drivers/cpufreq/elanfreq.c +++ b/drivers/cpufreq/elanfreq.c @@ -194,6 +194,7 @@ __setup("elanfreq=", elanfreq_setup); static struct cpufreq_driver elanfreq_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .get = elanfreq_get_cpu_frequency, .verify = cpufreq_generic_frequency_table_verify, .target_index = elanfreq_target, diff --git a/drivers/cpufreq/gx-suspmod.c b/drivers/cpufreq/gx-suspmod.c index d83e826..7bfad48 100644 --- a/drivers/cpufreq/gx-suspmod.c +++ b/drivers/cpufreq/gx-suspmod.c @@ -438,6 +438,7 @@ static int cpufreq_gx_cpu_init(struct cpufreq_policy *policy) * MediaGX/Geode GX initialize cpufreq driver */ static struct cpufreq_driver gx_suspmod_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .get = gx_get_cpuspeed, .verify = cpufreq_gx_verify, .target = cpufreq_gx_target, diff --git a/drivers/cpufreq/ia64-acpi-cpufreq.c b/drivers/cpufreq/ia64-acpi-cpufreq.c index 53c6ac6..907bf9a 100644 --- a/drivers/cpufreq/ia64-acpi-cpufreq.c +++ b/drivers/cpufreq/ia64-acpi-cpufreq.c @@ -344,6 +344,7 @@ acpi_cpufreq_cpu_exit ( static struct cpufreq_driver acpi_cpufreq_driver = { + .flags = CPUFREQ_SKIP_INITIAL_FREQ_CHECK, .verify = cpufreq_generic_frequency_table_verify, .target_index = acpi_cpufreq_target, .get = acpi_cpufreq_get, diff --git a/drivers/cpufreq/intel_pstate.c b/drivers/cpufreq/intel_pstate.c index 5f1cbae..6c8f5d3 100644 --- a/drivers/cpufreq/intel_pstate.c +++ b/drivers/cpufreq/intel_pstate.c @@ -725,7 +725,7 @@ static int intel_pstate_cpu_init(struct cpufreq_policy *policy) } static struct cpufreq_driver intel_pstate_driver = { -

[RFC part1 PATCH 0/7] Make ACPI core running on ARM64

by Hanjun Guo

This is the first part of making ACPI core running on ARM. PCI is optional on ARM64 but ACPI is dependent on PCI now, so in the first patch we try to make ACPI can be running without PCI. _PDC is requred for ACPI processor_core.c, but its related code is a little bit x86/ia64 dependent, so I rework _PDC related staff to make it more arch independent, and then introduce the skeleton of _PDC related for ARM64, it should be fully implemented after ACPI spec is ready for processor idle control. After that, arm-core.c is introduced so we can get ACPI table from UEFI, then we can parsed for SMP initialisation, GIC initialisation and for ACPI drivers. This patch set is based on: git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git origin/linux-next branch and plus Al Stone's v2 reduced hardware profile patch. Hanjun Guo (7): ACPI: Make ACPI core running without PCI on ARM64 ARM64 : Add dummy asm/cpu.h ACPI / processor_core: Rework _PDC related stuff to make it more arch-independent ARM64 / ACPI: Introduce the skeleton of _PDC related for ARM64 ARM64 / ACPI: Introduce arm_core.c and its related head file ARM64 / ACPI: Introduce lowlevel suspend function ARM64 / ACPI: Enable ARM64 in Kconfig arch/arm64/Kconfig | 2 + arch/arm64/include/asm/acpi.h | 93 +++++++++++++++ arch/arm64/include/asm/cpu.h | 25 ++++ arch/arm64/include/asm/processor.h | 11 ++ arch/arm64/kernel/process.c | 5 + arch/arm64/kernel/setup.c | 8 ++ drivers/acpi/Kconfig | 12 +- drivers/acpi/Makefile | 4 +- drivers/acpi/internal.h | 5 + drivers/acpi/osl.c | 16 +++ drivers/acpi/plat/Makefile | 1 + drivers/acpi/plat/arm-core.c | 226 ++++++++++++++++++++++++++++++++++++ drivers/acpi/processor_core.c | 27 ++--- drivers/acpi/reboot.c | 47 +++++--- drivers/pnp/pnpacpi/rsparser.c | 2 + 15 files changed, 452 insertions(+), 32 deletions(-) create mode 100644 arch/arm64/include/asm/acpi.h create mode 100644 arch/arm64/include/asm/cpu.h create mode 100644 drivers/acpi/plat/Makefile create mode 100644 drivers/acpi/plat/arm-core.c -- 1.7.9.5

[PATCH 0/3] CPUFreq: Cleanups for 3.14

by Viresh Kumar

Apart from the other patches, here are few minor cleanups for cpufreq core and drivers. The first two removes per-cpu cpufreq_show_table variable and moves that information in struct cpufreq_policy. And the last one removes unnecessary frozen variable/parameters.

[PATCH V4 0/6] cpufreq: suspend early/resume late: dpm_{suspend|resume}()

by Viresh Kumar

This patchset moves cpufreq callbacks to dpm_{suspend|resume}() from dpm_{suspend|resume}_noirq() for handling suspend/resume of cpufreq governors and core. This is required for early suspend and late resume of governors as there are drivers which want to change cpu frequency before suspending governors and they want to do it before devices get suspended, as some of them might be required to change frequency. Following patch is already pushed for v3.13 as it was required for fixing some bugs in there. And the remaining was decided to be pushed for v3.14. commit 5a87182aa21d6d5d306840feab9321818dd3e2a3 Author: Viresh Kumar <viresh.kumar(a)linaro.org> Date: Wed Nov 27 09:09:42 2013 +0530 cpufreq: suspend governors on system suspend/hibernate This is already tested by few people and so incorporating their Tested-by as well. For: v3.14.

[PATCH 1/5] cpufreq: Introduce cpufreq_notify_post_transition()

by Viresh Kumar

This introduces another routine cpufreq_notify_post_transition() which can be used to send POSTCHANGE notification for new freq with or without both {PRE|POST}CHANGE notifications for last freq in case of failures. This is useful at multiple places, specially for sending transition failure notifications.

[LSK PATCH] ARM: vexpress: tc2: fix hotplug/idle/kexec race on cluster power down

by Jon Medhurst (Tixy)

From: Lorenzo Pieralisi <lorenzo.pieralisi(a)arm.com> Commit 422a83fb1f9e84ead72b8ea15e21da6b8f20e57d upstream On the TC2 testchip, when all CPUs in a cluster enter standbywfi and commit a power down request, the power controller will wait for standbywfil2 coming from L2 cache controller to shut the cluster down. By the time all CPUs in a cluster commit a power down request and enter wfi, the power controller cannot backtrack, or put it another way, a CPU must not be allowed to complete execution independently of the power controller, the only way for it to resume properly must be upon wake-up IRQ pending and subsequent reset triggered from the power controller. Current MCPM back-end for TC2 disables the GIC CPU IF only when power down is committed through the tc2_pm_suspend() method, that makes sense since a suspended CPU is still online and can receive interrupts whereas a hotplugged CPU, since it is offline, migrated all IRQs and shutdown the per-CPU peripherals, hence their PPIs. The flaw with this reasoning is the following. If all CPUs in a clusters are entering a power down state either through CPU idle or CPU hotplug, when the last man successfully completes the MCPM power down sequence (and executes wfi), power controller waits for L2 wfi signal to quiesce the cluster and shut it down. If, when all CPUs are sitting in wfi, an online CPU hotplugs back in one of the CPUs in the cluster being shutdown, that CPU receives an IPI that causes wfi to complete (since tc2_pm_down() method does not disable the GIC CPU IF in that case - CPU being hotplugged out, not idle) and the power controller will never see the stanbywfil2 signal coming from L2 that is required for shutdown to happen and the system deadlocks. Further to this issue, kexec hotplugs secondary CPUs out during kernel reload/restart. Because kexec may (deliberately) trash the old kernel text, it is not OK for CPUs to follow the MCPM soft reboot path, since instructions after the WFI may have been replaced by kexec. If tc2_pm_down() does not disable the GIC cpu interface, there is a race between CPU powerdown in the old kernel and the IPI from the new kernel that triggers secondary boot, particularly if the powerdown is slow (due to L2 cache cleaning for example). If the new kernel wins the race, the affected CPU(s) will not really be reset and may execute garbage after the WFI. The only solution to this problem consists in disabling the GIC CPU IF on a CPU committed to power down regardless of the power down entry method (CPU hotplug or CPU idle). This way, CPU wake-up is under power controller control, which prevents unexpected wfi exit caused by a pending IRQ. This patch moves the GIC CPU IF disable call in the TC2 MCPM implementation from the tc2_pm_suspend() method to the tc2_pm_down() method to fix the mentioned race condition(s).

[PATCH V3 1/2] cpufreq: Make sure CPU is running on a freq from freq-table

by Viresh Kumar

Sometimes boot loaders set CPU frequency to a value outside of frequency table present with cpufreq core. In such cases CPU might be unstable if it has to run on that frequency for long duration of time and so its better to set it to a frequency which is specified in freq-table. This also makes cpufreq stats inconsistent as cpufreq-stats would fail to register because current frequency of CPU isn't found in freq-table. Because we don't want this change to effect boot process badly, we go for the next freq which is >= policy->cur ('cur' must be set by now, otherwise we will end up setting freq to lowest of the table as 'cur' is initialized to zero). In case current frequency doesn't match any frequency from freq-table, we throw warnings to user, so that user can get this fixed in their bootloaders or freq-tables. On some systems we can't really say what frequency we're running at the moment and so for these we have added another flag: CPUFREQ_SKIP_INITIAL_FREQ_CHECK.

[PATCH V3] cpufreq: Make sure CPU is running on a freq from freq-table

by Viresh Kumar

Sometimes boot loaders set CPU frequency to a value outside of frequency table present with cpufreq core. In such cases CPU might be unstable if it has to run on that frequency for long duration of time and so its better to set it to a frequency which is specified in freq-table. This also makes cpufreq stats inconsistent as cpufreq-stats would fail to register because current frequency of CPU isn't found in freq-table. Because we don't want this change to effect boot process badly, we go for the next freq which is >= policy->cur ('cur' must be set by now, otherwise we will end up setting freq to lowest of the table as 'cur' is initialized to zero). In case current frequency doesn't match any frequency from freq-table, we throw warnings to user, so that user can get this fixed in their bootloaders or freq-tables. On some systems we can't really say what frequency we're running at the moment and so for these we have added another flag: CPUFREQ_SKIP_INITIAL_FREQ_CHECK.

[PATCH] i2c: davinci: raw read and write endian fix

by Taras Kondratiuk

I2C IP block expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

easy kernel crash on TC2 with mainline kernel

by Nicolas Pitre

I've been banging my head on this one for quite a while now. The problem is that there is very little debug out put available. Could you see if you get the same? Mainline kernel (I'm using commit 527d151131 right now but older kernels are also affected). Most interesting config options: CONFIG_BL_SWITCHER=n CONFIG_ARCH_VEXPRESS_TC2_PM=y CONFIG_ARM_BIG_LITTLE_CPUIDLE=y CONFIG_ARM_BIG_LITTLE_CPUFREQ=y CONFIG_ARM_VEXPRESS_SPC_CPUFREQ=y To crash the kernel within 5 seconds: #!/bin/bash echo 0 > /sys/kernel/bL_switcher/active sleep 1 while true; do for i in 0 1 2 3 do echo 0 > /sys/devices/system/cpu/cpu$i/online done for i in 3 2 1 0 do echo 1 > /sys/devices/system/cpu/cpu$i/online done for i in 4 3 2 1 do echo 0 > /sys/devices/system/cpu/cpu$i/online done for i in 1 2 3 4 do echo 1 > /sys/devices/system/cpu/cpu$i/online done done What I get is: [...] CPU1: Booted secondary processor CPU0: Booted secondary processor Unable to handle kernel NULL pointer dereference at virtual address 0000000c pgd = c0004000 [ the output stops there ] The last CPU to be booted up is not always the same. Are you able to reproduce? Nicolas

[PATCH v2] ARM: OMAP4/highbank: Flush L2 cache before disabling

by Taras Kondratiuk

Kexec disables outer cache before jumping to reboot code, but it doesn't flush it explicitly. Flush is done implicitly inside of l2x0_disable(). But some SoC's override default .disable handler and don't flush cache. This may lead to a corrupted memory during Kexec reboot on these platforms. This patch adds cache flush inside of OMAP4 and Highbank outer_cache.disable() handlers to make it consistent with default l2x0_disable(). Acked-by: Rob Herring <rob.herring(a)calxeda.com> Acked-by: Santosh Shilimkar <santosh.shilimkar(a)ti.com> Acked-by: Tony Lindgren <tony(a)atomide.com> Signed-off-by: Taras Kondratiuk <taras.kondratiuk(a)linaro.org> --- I was not aware about Russell's patch tracker process, so this patch was not hooked there. Highbank moved to PSCI since then, so patch has to be slightly modified. Rob, are you still ok with this patch? v1..v2: Removed changes in highbank_suspend_finish since after commit dd68eb0 "ARM: highbank: adapt to use ARM PSCI calls" cache is not explicitly disabled there. v1: http://www.spinics.net/lists/linux-omap/msg98318.html RFC v2: https://patchwork.kernel.org/patch/2990231/ Make the fix specific to platforms that don't use l2x0_disable().
