Hi all Please find the patch for Save extra cpu cycles in getting slow/fast domain(Commit ID : 2926ff354657c02ad4e1c453138f8670d031d7c4) Description: In present code, it is compulsory to check if the cpu is in slowest/fastest domain before calling the functions; hmp_slower_domain() and hmp_faster_domain() to get the relative slower/faster domains. If the caller calls without checking, it will give invlaid address which can result in undefined behavior. Also in the functions hmp_select_slower_cpu(), hmp_select_faster_cpu() and hmp_best_little_cpu(), extra cpu cycles and instructions can be saved by changing the flow to get the relative slower/faster domain. As with this change the function hmp_slower_domain() and hmp_faster_domain() will itself take care of the condition if the current cpu is in slowest or fastest domain. So extra checks before getting the relative faster/slower domains can be avoided thus reducing function calls and prevent cpu cycles thus improving the performance.

[PATCH V6 0/3] OPP: Introduce OPP (V2) bindings

by Viresh Kumar

Hi, V5 got some more review comments, Acks, etc.. and they are all updated in V6. V5->V6: - Acks/RBY from Rob and Nishanth added - Lots of rewording suggested by Nishanth - OPP Descriptor node is named OPP Table node now and so 'opp' is replaced by 'opp_table' in examples, as suggested by Nishanth. - OPP entries are named as 'oppX' instead of 'entry*' as suggested by Nishanth. - Phandles to slow and fast OPPs in 2/3 are named appropriately. V4->V5: - opp-microamp fixed and rewritten as per Mark's suggestions. - shared-opp renamed as opp-shared, as that's the convention for other properties. - Dropped "[V4 3/3] OPP: Add 'opp-next' in operating-points-v2 bindings" as that was NAK'd by Mike T.. - Added [V5 3/3] based on Nishanth's suggestions. - Added an example for 2/3, multiple OPP nodes. - Other minor formatting.. - Existing binding: "operating-points" isn't deprecated now as platforms looking for simple bindings should be allowed to use them. - opp-khz is changed to opp-hz, examples updated. - turbo-mode explained V3->V4: - Dropped code changes as we are still concerned about bindings. - separated out into three patches, some of which might be NAK'd. :) - The first patch presents basic OPP stuff that was reviewed earlier. It also has support for multiple regulators, with values for both current and voltage. - Second patch is based on a special concern that Stephen had about multiple OPP tables, one of which the parsing code will select at runtime. - Third one separates out 'opp-next' or Intermediate freq support as Mike T. had few concerns over it. He wanted the clock driver to take care of this and so do not want it to be passed by DT and used by cpufreq. Also, there were concerns like the platform may not want to choose intermediate frequency as a target frequency for longer runs, which wasn't prevented in earlier bindings. And so it is kept separate to be NAK'd quietly, without much disturbances. ---------------x-------------------x------------------------ Current OPP (Operating performance point) device tree bindings have been insufficient due to the inflexible nature of the original bindings. Over time, we have realized that Operating Performance Point definitions and usage is varied depending on the SoC and a "single size (just frequency, voltage) fits all" model which the original bindings attempted and failed. The proposed next generation of the bindings addresses by providing a expandable binding for OPPs and introduces the following common shortcomings seen with the original bindings: - Getting clock/voltage/current rails sharing information between CPUs. Shared by all cores vs independent clock per core vs shared clock per cluster. - Support for specifying current levels along with voltages. - Support for multiple regulators. - Support for turbo modes. - Other per OPP settings: transition latencies, disabled status, etc.? - Expandability of OPPs in future. This patchset introduces new bindings "operating-points-v2" to get these problems solved. Refer to the bindings for more details. We now have multiple versions of OPP binding and only one of them should be used per device.

LSK feature request

by Gaurav Jindal (Gaurav Jindal)

Hi all Please find the patch for Handling the error while getting slower/faster CPU domain. (Commit ID 847c2761d5991c7b2a194d4254ac61f0e4aafbc4) Description: if caller does not check for slowest/fastest cpu domain before getting the next slower/faster CPU domain, error may occur if CPU is already in slowest/fastest domain. If the CPU is already in fastest domain, it will return the head pointer of the list instead of previous faster domain. In such case ,it should return the current CPU domain only. Similarly, if the CPU is already in slowest domain, it will return the head pointer of the list instead of next slower domain. In such case , it should return the current CPU domain only. Thanks.. Regards Gaurav Jindal +91-8800803297 CPCEX ID: gaurav.j

[PATCH LSK-3.10] Revert "mm: make vmstat_update periodic run conditional"

by Jon Medhurst (Tixy)

This reverts commit 7d252cd22a3f6cb459e8b012912dfd258157f7df because it has been implicated in kernel crashes when its workqueue timer is migrated during CPU hotplug. When HMP was initially being developed against a 3.4 derived kernel, it was observed that wakeups were occurring every 30s across every core to give the vmstat accounting a kick. This was causing a noticeable increase in energy consumption on the really quiet use cases such as audio and video playback. So commit 7d252cd22a was used which turned off the updates on idle CPUs to reduce that. On the 3.10 derived LSK this revert does not result in a significant increase in power consumption so it is assumed that changes since 3.4 have mitigated the initial problem. Signed-off-by: Jon Medhurst <tixy(a)linaro.org> --- Kevin, I based this on v3.10/topic/big.LITTLE as you requested. In doing so I noticed that topic didn't include the latest big-LITTLE-MP code as that was merged directly into LSK instead (commit b3c57d879f209074fbd0aa645274500151d69ec1). I don't know how much that matters but thought I'd point it out. include/linux/vmstat.h | 2 +- mm/vmstat.c | 95 ++++++++------------------------------------------ 2 files changed, 15 insertions(+), 82 deletions(-) diff --git a/include/linux/vmstat.h b/include/linux/vmstat.h index a30ab79..c586679 100644 --- a/include/linux/vmstat.h +++ b/include/linux/vmstat.h @@ -198,7 +198,7 @@ extern void __inc_zone_state(struct zone *, enum zone_stat_item); extern void dec_zone_state(struct zone *, enum zone_stat_item); extern void __dec_zone_state(struct zone *, enum zone_stat_item); -bool refresh_cpu_vm_stats(int); +void refresh_cpu_vm_stats(int); void refresh_zone_stat_thresholds(void); void drain_zonestat(struct zone *zone, struct per_cpu_pageset *); diff --git a/mm/vmstat.c b/mm/vmstat.c index b916a43..f42745e 100644 --- a/mm/vmstat.c +++ b/mm/vmstat.c @@ -14,7 +14,6 @@ #include <linux/module.h> #include <linux/slab.h> #include <linux/cpu.h> -#include <linux/cpumask.h> #include <linux/vmstat.h> #include <linux/sched.h> #include <linux/math64.h> @@ -433,12 +432,11 @@ EXPORT_SYMBOL(dec_zone_page_state); * with the global counters.
