The following were not used in any code:
__RTEMS_USE_TICKS_CPU_USAGE_STATISTICS__
__RTEMS_USE_TICKS_RATE_MONOTONIC_STATISTICS__
Both CPU Usage and Rate Monotonic Period Statistics are switched
to ticks resolution by configuring with __RTEMS_USE_TICKS_FOR_STATISTICS__
set to 1 on the configure command line.
The user has to explicitly enable this driver, choosing
it over the existing (and lame) CGA frame buffer driver
using USE_CIRRUS_GD5446=1 on the configure command line.
Implementation is tested to work on QEMU simulator only.
QEMU offers this hardware by default for PC platform but
it can be requested by "-vga cirrus" option for other PCI
aware systems in development/next QEMU releases as well.
Next sources have been used for driver implementation:
- RTEMS fb_vga.c - Rosimildo da Silva ( rdasilva@connecttel.com )
- Cirrus xf86 driver - used as VGA hardware setup documentation
- CL-GD5446 Technical Reference Manual, 1996, Second Edition
fb_vga.c has to be replaced by fb_cirrus.c in
rtems/c/src/lib/libbsp/i386/pc386/Makefile.am
to test the driver now. We expect to discus and include driver
section mechanism after driver testing.
Patch version 2:
- comments style updated according to Joel Sherrill review
- use static for variables and functions to compile without warnings

It is not so easy to use Termios for that. We already map CRNUL to CR,
thus we cannot ignore CRs. We could change the shell code to map CRNL
to a single line end, but this is more intrusive than the change here.
This code was reviewed as part of coverage analysis improvements. The
uncovered range had unclear documentation and the code itself was also
cleaned up to be easier to understand.

Joel editted the documentation for clarity, grammar and technical
correctness. I also moved it in the manual and added @findex
entries. The core work was just polished.

Due to the fact that CBS extends the EDF scheduler, most parts of EDF are
reused. One part is the allocation of the per-thread data. However, the CBS
per-thread structure defines a further element (while including the rest of
Scheduler_EDF_Per_thread)
