how to build linux kernel for P1011

alikobari · ‎01-14-2015

Hello,

I am trying to create a kernel for P1011 base board. I started by using an existing functional kernel configuration file .config. All component and memory are identical in this 2 board, just different processor. So I was hoping the kernel would work fine, but it did not and I am getting this error, after boot up:

I would appreciate any help in this matter,

Why are you using such an old kernel? I suggest trying the latest upstream kernel (or if you prefer, the latest Freescale SDK kernel). Or, if you really want to run this TimeSys kernel, you should seek support from TimeSys.

What was the "different processor" that you had been using?

BTW, it's hard to read logs that have a blank line between each line...

Hello Scott,

Thanks for reply, I have no choice except to use this kernel:: Linux version 3.0.34-ts-powerpc-rt55+ (akobari@ubuntu) (gcc version 4.6.3 (Timesys 20130114) which is part of a broader product component we use in my company, and I thought Linux version 3.0 is pretty up-to-date,. Any way that's not the issue because I am using the exact kernel for our other board, based on P2020 processor with no issue at all. I am also in contact with TimeSys community as well. I just want to get as much as help I can get to solve my problem. The log file I attached was captured by my editor, and I did not realized it has extra line in between!!!

Again I am using the same kernel by TimeSys with the same .config for P2020 based board, so there is an identical uImage for both and one is working fine the other stuck in this INFO message:

INFO: rcu_sched_state detected stall on CPU

it looks like the cpu is waiting for some events

Hello Ali Kobari,

A customer reported a similar problem previously, please check whether it would be helpful to use "nohz=off" Kernel boot parameter to disable dyntick-idle mode.

An idle CPU that is not receiving scheduling-clock interrupts is said to be "dyntick-idle". The CONFIG_NO_HZ_IDLE=y Kconfig option causes the kernel to avoid sending scheduling-clock interrupts to idle CPUs, which is critically important both to battery-powered devices and to highly virtualized mainframes.

Therefore, system with aggressive real-time response constraints often run CONFIG_HZ_PERIODIC=y kernels(or CONFIG_NO_HZ=n) in order to avoid degrading from-idle transition latencies.

This boot parameter "nohz=" that can be used to disable dyntick-idle mode in CONFIG_NO_HZ_IDLE=y kernel by specifying "nohz=off". By the default, the system boot with "nohz=on", enabling dyntick-idle mode.

Have a great day,
Yiping
