[PATCH V3 00/16] PM / OPP: Introduce APIs to transition OPPs

by Viresh Kumar

Hi Guys, This patchset add APIs in OPP layer to allow OPPs transitioning from within OPP layer. Currently all OPP users need to replicate the same code to switch between OPPs. While the same can be handled easily by OPP-core. The first 7 patches update the OPP core to introduce the new APIs and the next Nine patches update cpufreq-dt for the same. 11 out of 17 are already Reviewed by Stephen, only few are left :) I hope this is the last version of the series :) Testing: - Tested on exynos 5250-arndale (dual-cortex-A15) - Tested for both Old-V1 bindings and New V2 bindings - Tested with regulator names as: 'cpu-supply' and 'cpu0-supply' - Tested with Unsupported supply ranges as well, to check the opp-disable logic V2->V3: - Very minor updates. - find_supply_name() doesn't return an error value now, and so its callers don't check for it. - And so we don't need to initialize name to NULL Viresh Kumar (16): PM / OPP: get/put regulators from OPP core PM / OPP: Disable OPPs that aren't supported by the regulator PM / OPP: Introduce dev_pm_opp_get_max_volt_latency() PM / OPP: Introduce dev_pm_opp_get_max_transition_latency() PM / OPP: Parse clock-latency and voltage-tolerance for v1 bindings PM / OPP: Manage device clk PM / OPP: Add dev_pm_opp_set_rate() cpufreq: dt: Convert few pr_debug/err() calls to dev_dbg/err() cpufreq: dt: Rename 'need_update' to 'opp_v1' cpufreq: dt: OPP layers handles clock-latency for V1 bindings as well cpufreq: dt: Pass regulator name to the OPP core cpufreq: dt: Unsupported OPPs are already disabled cpufreq: dt: Reuse dev_pm_opp_get_max_transition_latency() cpufreq: dt: Use dev_pm_opp_set_rate() to switch frequency cpufreq: dt: No need to fetch voltage-tolerance cpufreq: dt: No need to allocate resources anymore drivers/base/power/opp/core.c | 420 ++++++++++++++++++++++++++++++++++++++++++ drivers/base/power/opp/opp.h | 13 ++ drivers/cpufreq/cpufreq-dt.c | 300 +++++++++++------------------- include/linux/pm_opp.h | 27 +++ 4 files changed, 565 insertions(+), 195 deletions(-) -- 2.7.1.370.gb2aa7f8

[PATCH 00/34] CPUFreq: Move freq change notifications out of drivers

by Viresh Kumar

Another 452 lines gone :) Total stats upto now for all the 5 patchsets: Viresh Kumar (186): ... 69 files changed, 700 insertions(+), 2451 deletions(-) Net: 1751 lines gone.. -----x-------------x---------------- Most of the drivers do following in their ->target_index() routines: struct cpufreq_freqs freqs; freqs.old = old freq... freqs.new = new freq... cpufreq_notify_transition(policy, &freqs, CPUFREQ_PRECHANGE); /* Change rate here */ cpufreq_notify_transition(policy, &freqs, CPUFREQ_POSTCHANGE); This is replicated over all cpufreq drivers today and there doesn't exists a good enough reason why this shouldn't be moved to cpufreq core instead. There are few special cases though, like exynos5440, which doesn't do everything on the call to ->target_index() routine and call some kind of bottom halves for doing this work, work/tasklet/etc.. They may continue doing notification from their own code and so this patch introduces another flag: CPUFREQ_NO_NOTIFICATION, which will be set by such drivers. This is Fifth part of my cleanup work for CPUFreq, first three are (And obviously its rebased over them): 1: cpufreq: Introduce cpufreq_table_validate_and_show() https://lkml.org/lkml/2013/8/8/263 2: cpufreq: define generic routines for cpufreq drivers https://lkml.org/lkml/2013/8/10/48 3.

[RESEND PATCH] arm64: kgdb: fix single stepping

by AKASHI Takahiro

Jason, Could you please review my patch below? See also arm64 maintainer's comment: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-January/313712.h… Thanks, -Takahiro AKASHI I tried to verify kgdb in vanilla kernel on fast model, but it seems that the single stepping with kgdb doesn't work correctly since its first appearance at v3.15. On v3.15, 'stepi' command after breaking the kernel at some breakpoint steps forward to the next instruction, but the succeeding 'stepi' never goes beyond that. On v3.16, 'stepi' moves forward and stops at the next instruction just after enable_dbg in el1_dbg, and never goes beyond that. This variance of behavior seems to come in with the following patch in v3.16: commit 2a2830703a23 ("arm64: debug: avoid accessing mdscr_el1 on fault paths where possible") This patch (1) moves kgdb_disable_single_step() from 'c' command handling to single step handler. This makes sure that single stepping gets effective at every 's' command. Please note that, under the current implementation, single step bit in spsr, which is cleared by the first single stepping, will not be set again for the consecutive 's' commands because single step bit in mdscr is still kept on (that is, kernel_active_single_step() in kgdb_arch_handle_exception() is true). (2) re-implements kgdb_roundup_cpus() because the current implementation enabled interrupts naively. See below. (3) removes 'enable_dbg' in el1_dbg. Single step bit in mdscr is turned on in do_handle_exception()-> kgdb_handle_expection() before returning to debugged context, and if debug exception is enabled in el1_dbg, we will see unexpected single- stepping in el1_dbg. Since v3.18, the following patch does the same: commit 1059c6bf8534 ("arm64: debug: don't re-enable debug exceptions on return from el1_dbg) (4) masks interrupts while single-stepping one instruction. If an interrupt is caught during processing a single-stepping, debug exception is unintentionally enabled by el1_irq's 'enable_dbg' before returning to debugged context. Thus, like in (2), we will see unexpected single-stepping in el1_irq. Basically (1) and (2) are for v3.15, (3) and (4) for v3.1[67]. * issue fixed by (2): Without (2), we would see another problem if a breakpoint is set at interrupt-sensible places, like gic_handle_irq(): KGDB: re-enter error: breakpoint removed ffffffc000081258 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 650 at kernel/debug/debug_core.c:435 kgdb_handle_exception+0x1dc/0x1f4() Modules linked in: CPU: 0 PID: 650 Comm: sh Not tainted 3.17.0-rc2+ #177 Call trace: [<ffffffc000087fac>] dump_backtrace+0x0/0x130 [<ffffffc0000880ec>] show_stack+0x10/0x1c [<ffffffc0004d683c>] dump_stack+0x74/0xb8 [<ffffffc0000ab824>] warn_slowpath_common+0x8c/0xb4 [<ffffffc0000ab90c>] warn_slowpath_null+0x14/0x20 [<ffffffc000121bfc>] kgdb_handle_exception+0x1d8/0x1f4 [<ffffffc000092ffc>] kgdb_brk_fn+0x18/0x28 [<ffffffc0000821c8>] brk_handler+0x9c/0xe8 [<ffffffc0000811e8>] do_debug_exception+0x3c/0xac Exception stack(0xffffffc07e027650 to 0xffffffc07e027770) ...

Kgdb then calls kgdb_roundup_cpus() to sync with other cpus. Current kgdb_roundup_cpus() unmasks interrupts temporarily to use smp_call_function(). This eventually allows another interrupt to occur and likely results in hitting a breakpoint at gic_handle_irq() again since debug exception is always enabled in el1_irq. We can avoid this issue by specifying "nokgdbroundup" in kernel parameter, but this will also leave other cpus be in unknown state in terms of kgdb, and may result in interfering with kgdb activity.

[PATCH v3 0/3] *** Latency histograms - IRQSOFF,PREEMPTOFF ***

by Binoy Jayan

Hi, Thank you Steven and Daniel for reviewing v1 and providing suggestions. These set of patches [v3] capture latency events caused by interrupts and premption disabled in kernel. The patches are based on the hist trigger feature developed by Tom Zanussi. v2: https://lkml.org/lkml/2016/8/24/296 Mount Debugfs mount -t debugfs nodev /sys/kernel/debug Examples of triggers: echo 'hist:key=latency.log2:val=hitcount:sort=latency' > /sys/kernel/debug/tracing/events/latency/latency_preempt/trigger echo 'hist:key=cpu,latency:val=hitcount:sort=latency if cpu==1' > /sys/kernel/debug/tracing/events/latency/latency_preempt/trigger echo 'hist:key=ltype,cpu:val=latency:sort=ltype,cpu if ltype==0' > /sys/kernel/debug/tracing/events/latency/latency_preempt/trigger Histogram output: cat /sys/kernel/debug/tracing/events/latency/latency_preempt/hist Changes from v2 as per comments from Daniel - Use single tracepoint for irq/preempt/critical timings by introducing a trace type field to differentiate trace type in the same tracepoint. The suspicious RCU usage error was fixed and made part of Daniel's bugfix. TODO: 1. perf interface. Not sure if this is needed 2. Latency histograms - process wakeup latency Binoy Binoy Jayan (2): tracing: Add trace_irqsoff tracepoints tracing: Histogram for missed timer offsets Daniel Wagner (1): tracing: Deference pointers without RCU checks include/linux/hrtimer.h | 3 ++ include/linux/rculist.h | 36 ++++++++++++++++++++ include/linux/tracepoint.h | 4 +-- include/trace/events/latency.h | 68 +++++++++++++++++++++++++++++++++++++ kernel/time/hrtimer.c | 39 +++++++++++++++++++++ kernel/trace/trace_events_filter.c | 4 +-- kernel/trace/trace_events_trigger.c | 6 ++-- kernel/trace/trace_irqsoff.c | 45 +++++++++++++++++++++++- 8 files changed, 197 insertions(+), 8 deletions(-) create mode 100644 include/trace/events/latency.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
