Hi Khaled, I would suggest to follow these instructions: http://www.gem5.org/ARM_Linux_Kernel
Once you have that working _without_ any modifications you can start experimenting.

You can find a similar option with "make menuconfig". The BogoMIPS stuff, you'll probably need to remove or comment part of code in the kernel sources. Regards, -- Fernando A. Endo, Post-doc INRIA Rennes-Bretagne Atlantique France 2015-12-11 12:13 GMT-02:00 Khaled Attia <[email protected]<mailto:[email protected]>>: Hi Fernando, Thanks a lot. But what do you actually mean by "copy-paste the initial kernel args"? Also, how to disable BogoMIPS ? I don't see any configuration option for it. Or do you mean I should find its code in the source and remove it? Are there any further modification needed similar to disabling BogoMIPS? -- Khaled M.
