Does this include headers ?
POK separates kernel and partition code. The kernel code is not
affected
by the partitions running on top. And each partition has the
'knowledge'
of how to communicate with the kernel. libpart.a consits of this
communication code or 'partition base code' and the implementation of
the functions in virtualizationlayercpu.h and virtualizationlayerbsp.h.
Or what do you mean with headers?
Where do the virtualizationlayercpu.h and virtualizationlayerbsp.h come
from and live ?
In libbsp/i386/virtualpok/include. The files are part of this patch.
What is used to build the library externally ?
I do not think having headers in RTEMS for a library built outside is a
good idea. An interface change in the library not reflected in RTEMS
headers will be difficult to find.
The header files define the virtualization layer in RTEMS. They are not
part of POK.
Yet the code is built by POK. I am a little confused by this.
The header files define the functions a host has to
implement to run this particular RTEMS BSP.
Sure.
All hardware interactions a BSP/CPU does go through this layer and are
handled on the host system. RTEMS defines the function necessary and POK
is providing the implementation via libpart.a.
How does POK see these definitions so it can build the library ?
For examples, the console driver calls _BSP_Virtual_Char_read/write,
defined in virtualizationlayerbsp.h.
The implementation is done in POK and passed to RTEMS at compile time
via libpart.a
What is the interface used in POK to build this RTEMS interface ?
