How hard it is port VxWorks code to Linux?

Guys:

A porting question, Our systems is running with VxWorks (all are
tasks), how hard it is port to Linux. Does any tasks concept available
in Linux?.

Also how the Interrupt will work in Linux?. We have many ISR's in
VxWorks code, can it run directly on Linux?.

Thanks in advance.

Yes.

How the things works out in Linux compare to VxWorks task mechanism?.

Also I am reading Linux Book, it was talkiung about Bottom half, what
is this Bottom half, for eample if there is 3 interrupts serving three
different things, can one BottomHalf should be OK?. or three BH's
required, how it is different from ISR?.

Thanks.

Why can't you use Google ? That why you would find out about Linux
processes and threads.

No, you need a bottom half for each physical interrupt.
