In fact, in some architectures, the searching ranges on +events are limited in the same socket or node where the CPU locates, +while the load balance on tick searchs all. + +For example, assume CPU Z is relatively far from CPU X.

If you +want to assign bandwidth to another group, reduce the root group's bandwidth +and assign some or all of the difference to another group. + +Realtime group scheduling means you have to assign a portion of total CPU +bandwidth to the group before it will accept realtime tasks. Therefore you will +not be able to run realtime tasks as any user other than root until you have +done that, even if the user has the rights to run processes with realtime +priority! + + +2.3 Basis for grouping tasks +---------------------------- + +There are two compile-time settings for allocating CPU bandwidth. These are +configured using the "Basis for grouping tasks" multiple choice menu under +General setup > Group CPU Scheduler: + +a. CONFIG_USER_SCHED (aka "Basis for grouping tasks" = "user id") + +This lets you use the virtual files under +"/sys/kernel/uids/<uid>/cpu_rt_runtime_us" to control he CPU time reserved for +each user . + +The other option is: + +.o CONFIG_CGROUP_SCHED (aka "Basis for grouping tasks" = "Control groups") + +This uses the /cgroup virtual file system and "/cgroup/<cgroup>/cpu.rt_runtime_us" +to control the CPU time reserved for each control group instead. + +For more information on working with control groups, you should read +Documentation/cgroups.txt as well. + +Group settings are checked against the following limits in order to keep the configuration +schedulable: \Sum_{i} runtime_{i} / global_period <= global_runtime / global_period -in order to keep the configuration schedulable. +For now, this can be simplified to just the following (but see Future plans): + + \Sum_{i} runtime_{i} <= global_runtime + + +3. Future plans +=============== + +There is work in progress to make the scheduling period for each group +("/sys/kernel/uids/<uid>/cpu_rt_period_us" or +"/cgroup/<cgroup>/cpu.rt_period_us" respectively) configurable as well. + +The constraint on the period is that a subgroup must have a smaller or +equal period to its parent. But realistically its not very useful _yet_ +as its prone to starvation without deadline scheduling. + +Consider two sibling groups A and B; both have 50% bandwidth, but A's +period is twice the length of B's. + +* group A: period=100000us, runtime=10000us + - this runs for 0.01s once every 0.1s + +* group B: period= 50000us, runtime=10000us + - this runs for 0.01s twice every 0.1s (or once every 0.05 sec). + +This means that currently a while (1) loop in A will run for the full period of +B and can starve B's tasks (assuming they are of lower priority) for a whole +period. + +The next project will be SCHED_EDF (Earliest Deadline First scheduling) to bring +full deadline scheduling to the linux kernel. Deadline scheduling the above +groups and treating end of the period as a deadline will ensure that they both +get their allocated time. + +Implementing SCHED_EDF might take a while to complete. Priority Inheritance is +the biggest challenge as the current linux PI infrastructure is geared towards +the limited static priority levels 0-139. With deadline scheduling you need to +do deadline inheritance (since priority is inversely proportional to the +deadline delta (deadline - now). + +This means the whole PI machinery will have to be reworked - and that is one of +the most complex pieces of code we have. diff --git a/MAINTAINERS b/MAINTAINERS index 897e5ebb2ab..a46ec689f0a 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -486,6 +486,12 @@ M: kernel@wantstofly.org L: linux-arm-kernel@lists.arm.linux.org.uk (subscribers-only) S: Maintained +ARM/GUMSTIX MACHINE SUPPORT +P: Steve Sakoman +M: sakoman@gmail.com +L: linux-arm-kernel@lists.arm.linux.org.uk (subscribers-only) +S: Maintained + ARM/HP JORNADA 7XX MACHINE SUPPORT P: Kristoffer Ericson M: kristoffer.ericson@gmail.com diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 1165a8fb99c..d8d253285a9 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -255,6 +255,7 @@ config ARCH_EP93XX select ARM_AMBA select ARM_VIC select GENERIC_GPIO + select HAVE_GPIO_LIB help This enables support for the Cirrus EP93xx series of CPUs. @@ -377,15 +378,17 @@ config ARCH_MXC help Support for Freescale MXC/iMX-based family of processors -config ARCH_ORION +config ARCH_ORION5X bool "Marvell Orion" depends on MMU select PCI select GENERIC_GPIO select GENERIC_TIME select GENERIC_CLOCKEVENTS + select PLAT_ORION help - Support for Marvell Orion System on Chip family. + Support for the following Marvell Orion 5x series SoCs: + Orion-1 (5181), Orion-NAS (5182), Orion-2 (5281.) config ARCH_PNX4008 bool "Philips Nexperia PNX4008 Mobile" @@ -422,10 +425,15 @@ config ARCH_SA1100 bool "SA1100-based" select ISA select ARCH_DISCONTIGMEM_ENABLE + select ARCH_SPARSEMEM_ENABLE + select ARCH_SELECT_MEMORY_MODEL select ARCH_MTD_XIP select GENERIC_GPIO select GENERIC_TIME + select GENERIC_CLOCKEVENTS + select TICK_ONESHOT select HAVE_IDE + select HAVE_GPIO_LIB help Support for StrongARM 11x0 based boards. @@ -468,6 +476,7 @@ config ARCH_DAVINCI config ARCH_OMAP bool "TI OMAP" select GENERIC_GPIO + select HAVE_GPIO_LIB select GENERIC_TIME select GENERIC_CLOCKEVENTS help @@ -516,7 +525,7 @@ source "arch/arm/mach-omap1/Kconfig" source "arch/arm/mach-omap2/Kconfig" -source "arch/arm/mach-orion/Kconfig" +source "arch/arm/mach-orion5x/Kconfig" source "arch/arm/plat-s3c24xx/Kconfig" source "arch/arm/plat-s3c/Kconfig" @@ -563,6 +572,9 @@ config ARCH_ACORN config PLAT_IOP bool +config PLAT_ORION + bool + source arch/arm/mm/Kconfig config IWMMXT @@ -650,7 +662,7 @@ source "kernel/time/Kconfig" config SMP bool "Symmetric Multi-Processing (EXPERIMENTAL)" - depends on EXPERIMENTAL && REALVIEW_EB_ARM11MP + depends on EXPERIMENTAL && (REALVIEW_EB_ARM11MP || MACH_REALVIEW_PB11MP) help This enables support for systems with more than one CPU.
