Hi,

We are trying a write a bare metal test code for Switching tasks from A15 Core 
to A7 core.
As of now we have this article to start with https://lwn.net/Articles/481055/.

Can the list help us in
a) Where (file/directory ) in Linux kernel code that does the switching code 
(arch specific) for 5420 ?

There is no mainline support for big.LITTLE on Exynos5420 yet. There were some patches [1] posted for MCPM support, though.

[1] http://www.spinics.net/lists/arm-kernel/msg321666.html

b) Any test cases for big little on 5420 ?

I'm not aware of any, but Exynos5 is not the primary platform I work on.

Best regards,
Tomasz
