nanogui: Thread: VxWorks?

Hi Everyone,

I just joined the list so please forgive me if this is offtopic or sent
incorrectly.

I'm currently working on a project involving a browser on top of VxWorks.
We've been having alot of problems with the browser vendor and I'm hoping to
find an alternative solution.  I was checking out microwindows the other day
I happened to see ViewML.  It looks like it could be a viable replacement
for an expensive proprietary solution.

My question is: Does anyone know of a VxWorks port of microwindows or
attempted such a thing in the past?  Also, is there a "porting faq" of some
kind to help people trying to port to new architectures/platforms?

P.S.: If you're wondering why I'm using VxWorks instead of linux, its
because I work for WindRiver and I'm forced to! :)

I am also looking into using Microwindows in a VxWorks
environment.  Let's talk to coordinate our work.

I would like to help standardize non-Linux or non-POSIX 
interfaces from Microwindows to other RTOSs, it's
exciting that Microwindows is being considered on some
well-known embedded operating systems.

Rosimildo ported Microwindows to RTEMS a few
months ago, and we worked to build a framebuffer
interface that Microwindows uses to talk to the OS
entry points.  It would be nice if that interface had
the same names on the Microwindows side, so that
it becomes easier to get it running on different platforms.

As a first round, we tried to emulate the basic framebuffer
query functions, as well as a new GsSelect() implementation.
With the RTEMS implementation, a standard Microwindows
screen driver was written that used this sample "standard"
subdriver, while keyboard and mouse were essentially
written from scratch underneath the GsSelect call.

Keep me posted on your needs, I'll be glad to help.

Regards,

Greg

Brent,

For RTEMS, was defined a "thin layer" ( everybody loves this !! ),
that is similar to lunix frambuffer, and it should be RTOS
independent. Look at these modules:

  src/drivers/input_rtems.c
  src/drivers/scr_rtems.c

We might have to change the modules name to something more
generic, it they fit your needs.


Regarging the GsSelect(), RTEMS is a bit different, because
the current implemetnation of select() under RTEMS, only
works with sockets, and it could not be used in the
MicroWindows context.

If you need help, please do not hesitate to ask. :-).

Rosimildo.
