Yes, but it is easy to "emulate" this call. IIRC, RTEMS already
supports it. RTEMS being a POSIX based RTOS "match" better with
Linux code.
I was just wondering about the benefits of porting either one in the
long run.
+ which one has large development community
+ availability of drivers
+ applications
How about Linux Frame Buffer ( FB ) ?
Is there any advantage of it over SVGA ?
