[PATCH V2] ARM: trace: Add tracepoint for the Inter Processor Interrupt

by Daniel Lezcano

The Inter Processor Interrupt is used on ARM to tell another processor to do a specific action. This is mainly used to emulate a timer interrupt on an idle cpu, force a cpu to reschedule or run a function on another processor context. Add a tracepoint when raising an IPI and in the entry/exit handler functions. When a cpu raises an IPI, the targeted cpus is an interesting information, the cpumask conversion in hexa is added in the trace using the cpumask_scnprintf function. Tested-on Vexpress TC2 (5 processors).

[PATCH V2 Resend 00/34] CPUFreq Cleanup Part III

by Viresh Kumar

As Part II is already in your linux-next branch, I am sending Part III for inclusion in bleeding-edge. This is oriented around a light weight ->target_index() routine. CPUFreq notifications would be moved to CPUFreq core in the next patchset that I will send, as you suggested not to merge multiple series together.. Although both of them are oriented towards a light weight ->target_index() routine. This is rebased over your bleeding-edge branch + "cpufreq: create per policy rwsem instead of per CPU cpu_policy_rwsem".. Thanks.

Ah, right. I think that the fncpy() function should work. This is for the precise purpsoe of copying a function body from one place to another, while reatining the Thumb bit. I have to disappear early to today, but I'll try and follow up. Currently, I have the following, but I've not been able to test it yet. If you'd like to give it a try, that would be much appreciated. Cheers ---Dave >From 94925667e650202e1baf74e1ff223671d316401d Mon Sep 17 00:00:00 2001 From: Dave Martin <Dave.Martin(a)arm.com> Date: Tue, 15 Oct 2013 11:48:46 +0100 Subject: [PATCH] ARM: kexec: Use the right ISA for relocate_new_kernel Copying a function with memcpy() and then trying to execute the result isn't portable to Thumb. This patch modifies the kexec soft restart code to copy its assembler trampoline relocate_new_kernel() using fncpy() instead, so that relocate_new_kernel can be in the same ISA as the rest of the kernel without problems.
