[PATCH] bootwrapper: Enable non-secure access to the CCI

by Jon Medhurst (Tixy)

We boot the kernel in non-secure mode and by default access to the CCI device is not enabled for non-secure access, so we must enable this if we want Linux to manage CPU hotplug on big.LITTLE models.

[PATCH] bootwrapper: Fix check for architected timer

by Jon Medhurst (Tixy)

From: Will Deacon <will.deacon(a)arm.com> We need to set the flags when checking the feature register. Signed-off-by: Will Deacon <will.deacon(a)arm.com> --- I found this patch in another fork of the bootwrapper and it looks like something we should have. On the A15 and big.LITTLE setups I've tested it makes no difference so I guess the z flag was already clear or the architected timers are already running at 24MHz. boot.S | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/boot.S b/boot.S index 40ebd33..dd453e3 100644 --- a/boot.S +++ b/boot.S @@ -78,7 +78,7 @@ start: @ mrc p15, 0, r0, c0, c1, 1 @ CPUID_EXT_PFR1 lsr r0, r0, #16 - and r0, r0, #1 @ Check generic timer support + ands r0, r0, #1 @ Check generic timer support beq 1f ldr r0, =24000000 @ 24MHz timer frequency mcr p15, 0, r0, c14, c0, 0 @ CNTFRQ -- 1.7.10.4

[RFC v2 PATCH 0/2] sched: Integrating Per-entity-load-tracking with the core scheduler

by Preeti U Murthy

This approach aims to retain the current behavior of load balancer with the change being only in the metric consumed during load balancing, without unnecessary introduction of new variables.This RFC has been posted to evaluate its design;to see if this is the right way to go about introducing per-entity-load-tracking metric for the consumers of the same; in this specific case,the load balancer.Once the design has been approved off,I can go around to testing it. The patch has been based out of tip-master:HEAD at commit 8a1d31c703d Subject:Merge branch 'x86/urgent' Grateful to Peter Zijlstra and Ingo Molnar for their valuable feedback on v1 of the RFC which was the foundation for this version. PATCH[1/2] Aims at enabling usage of Per-Entity-Load-Tracking for load balacing PATCH[2/2] The crux of the patchset lies here. --- Preeti U Murthy (2): sched: Revert temporary FAIR_GROUP_SCHED dependency for load-tracking sched: Use Per-Entity-Load-Tracking metric for load balancing include/linux/sched.h | 9 +----- kernel/sched/core.c | 19 +++++------- kernel/sched/fair.c | 76 +++++++++++++++++++++---------------------------- kernel/sched/sched.h | 9 +----- 4 files changed, 43 insertions(+), 70 deletions(-) -- Preeti U Murthy
