nanogui: Thread: why asserts are failing

:  assert ( "drivers/vgaplan4.c", line=173, 
:            msg=0x129403 "y2 >= 0 && y2 < psd->yres")

Rosimildo -
    The reason that asserts aren't working is because
the vga driver has only been tested on the ELKS system,
which lacks an assert() macro.  Thus, the assert()'s have
never been compiled in.... ;-)

I've never been able to get my system running vga16 framebuffer,
so I can't test the damn driver without running ELKS.

Greg,

Thanks for your help. Now we have RTEMS with remote GDB
and asserts. So, I think we are covered. :-).

I still working out some issues with RTEMS, and hopefully
have a patch pretty soon.
BTW, I am using the cut that you merged. There were very
few changes to get it compiling.

So far I have merged the "screen" driver for RTEMS with the
BIOS based one. I'll leave the module called src_bios.c
and later we might want to rename it to scr_hwvga.c as
you suggested perviously.

Great.  Hopefully the single HWINIT define can control whether
or not any bios calls get made.  Since the rom character set is
in the bios, and you're using the hardware only (cool), then
there may need to be one other define to include the genfonts
stuff rather than romfonts.  Or perhaps you can split that
stuff out of the scr_bios.c file and have the font stuff in two
other files, one for bios and one for genfonts.
