[PATCH] clockevents: Add (missing) default case for switch blocks

by Viresh Kumar

Many clockevent drivers are using a switch block for handling modes in their ->set_mode() callback. Some of these do not have a 'default' case and adding a new mode in the 'enum clock_event_mode', starts giving following warnings for these platforms about unhandled modes (e.g. XXX). warning: enumeration value ‘XXX’ not handled in switch [-Wswitch] This patch adds default cases for them. In order to keep things simple, add following to the switch blocks: default: break; This can lead to different behavior for individual cases. 1) Some of the drivers don't have any special stuff in their ->set_mode() callback before or after the switch blocks. And so this default case would simply return for them without any updates to the clockevent device. 2) But in some cases, the clockevent device is disabled/stopped as soon as we enter the ->set_mode() callback and is enabled within the switch block or after it. And the clockevent device *may* stay disabled for default case. The rationale behind only adding a 'break' was that the default case *will never* be hit during execution of code. All new modes (beyond RESUME) are handled with mode specific ->set_mode_*() callbacks and ->set_mode() is never called for them. And all modes before and including RESUME are already explicitly handled by the clockevent drivers.

[PATCH v2] spi: qup: Add DMA capabilities

by Stanimir Varbanov

From: Andy Gross <agross(a)codeaurora.org> This patch adds DMA capabilities to the spi-qup driver. If DMA channels are present, the QUP will use DMA instead of block mode for transfers to/from SPI peripherals for transactions larger than the length of a block. Signed-off-by: Andy Gross <agross(a)codeaurora.org> Signed-off-by: Stanimir Varbanov <stanimir.varbanov(a)linaro.org> --- This is reworked version with comments addressed - use SPI core DMA mapping code - implemented .can_dma callback - use dmaengine api's to account deferred_probe First version can be found at [1].

[PATCH RESEND v9 00/10] sched: consolidation of CPU capacity and usage

by Vincent Guittot

This patchset consolidates several changes in the capacity and the usage tracking of the CPU. It provides a frequency invariant metric of the usage of CPUs and generally improves the accuracy of load/usage tracking in the scheduler. The frequency invariant metric is the foundation required for the consolidation of cpufreq and implementation of a fully invariant load tracking. These are currently WIP and require several changes to the load balancer (including how it will use and interprets load and capacity metrics) and extensive validation. The frequency invariance is done with arch_scale_freq_capacity and this patchset doesn't provide the backends of the function which are architecture dependent. As discussed at LPC14, Morten and I have consolidated our changes into a single patchset to make it easier to review and merge. During load balance, the scheduler evaluates the number of tasks that a group of CPUs can handle. The current method assumes that tasks have a fix load of SCHED_LOAD_SCALE and CPUs have a default capacity of SCHED_CAPACITY_SCALE. This assumption generates wrong decision by creating ghost cores or by removing real ones when the original capacity of CPUs is different from the default SCHED_CAPACITY_SCALE. With this patch set, we don't try anymore to evaluate the number of available cores based on the group_capacity but instead we evaluate the usage of a group and compare it with its capacity. This patchset mainly replaces the old capacity_factor method by a new one and keeps the general policy almost unchanged. These new metrics will be also used in later patches. The CPU usage is based on a running time tracking version of the current implementation of the load average tracking. I also have a version that is based on the new implementation proposal [1] but I haven't provide the patches and results as [1] is still under review. I can provide change above [1] to change how CPU usage is computed and to adapt to new mecanism. Change since V8 - reorder patches Change since V7 - add freq invariance for usage tracking - add freq invariance for scale_rt - update comments and commits' message - fix init of utilization_avg_contrib - fix prefer_sibling Change since V6 - add group usage tracking - fix some commits' messages - minor fix like comments and argument order Change since V5 - remove patches that have been merged since v5 : patches 01, 02, 03, 04, 05, 07 - update commit log and add more details on the purpose of the patches - fix/remove useless code with the rebase on patchset [2] - remove capacity_orig in sched_group_capacity as it is not used - move code in the right patch - add some helper function to factorize code Change since V4 - rebase to manage conflicts with changes in selection of busiest group Change since V3: - add usage_avg_contrib statistic which sums the running time of tasks on a rq - use usage_avg_contrib instead of runnable_avg_sum for cpu_utilization - fix replacement power by capacity - update some comments Change since V2: - rebase on top of capacity renaming - fix wake_affine statistic update - rework nohz_kick_needed - optimize the active migration of a task from CPU with reduced capacity - rename group_activity by group_utilization and remove unused total_utilization - repair SD_PREFER_SIBLING and use it for SMT level - reorder patchset to gather patches with same topics Change since V1: - add 3 fixes - correct some commit messages - replace capacity computation by activity - take into account current cpu capacity [1] https://lkml.org/lkml/2014/10/10/131 [2] https://lkml.org/lkml/2014/7/25/589 Morten Rasmussen (2): sched: Track group sched_entity usage contributions sched: Make sched entity usage tracking scale-invariant Vincent Guittot (8): sched: add utilization_avg_contrib sched: remove frequency scaling from cpu_capacity sched: make scale_rt invariant with frequency sched: add per rq cpu_capacity_orig sched: get CPU's usage statistic sched: replace capacity_factor by usage sched: add SD_PREFER_SIBLING for SMT level sched: move cfs task on a CPU with higher capacity include/linux/sched.h | 21 ++- kernel/sched/core.c | 15 +- kernel/sched/debug.c | 12 +- kernel/sched/fair.c | 369 ++++++++++++++++++++++++++++++++------------------ kernel/sched/sched.h | 15 +- 5 files changed, 276 insertions(+), 156 deletions(-) -- 1.9.1
