Getting started with Linux on ARVIA V multiprocessors

Hello,

Can anyone give some pointers as to how to start studying the develpoment with Linux on ARVIA V.

I need to deal with multiprocessor on ARVIA V (ARM and NIOS).

Now I'm not sure as to which OS is best suitable.

NIOS need to interface PCI express - I'm not sure that the basic developments with EDS is suitable for that - it seems that it only supporsts uC and I'm not sure if uC supports PCIe. This leaves me with Linux.

1. How to get started with Linux on ARVIA V ? (The EDS is more about uC, so I'm not sure as to the development on Linux).

2. Does Linux support the mutex (test-and-set) which is required for multiprocessor access on interfaces on single fpga ?

3. Does Linux suport ARVIA V interfaces (ethernet, rs-232). Or do I need to port the HAL implementation in Nios for example into Linux kernel ?

4. Where can I find the SDK for linux ARM (and Linux Nios) with ARVIA ?

Regards,

Ran
