==============================================================================
|
|
||||||
Using the Simple DirectMedia Layer with OpenBSD/wscons
|
|
||||||
==============================================================================
|
|
||||||
|
|
||||||
The wscons SDL driver can be used to run SDL programs on OpenBSD
|
|
||||||
without running X. So far, the driver only runs on the Sharp Zaurus,
|
|
||||||
but the driver is written to be easily extended for other machines.
|
|
||||||
The main missing pieces are blitting routines for anything but 16 bit
|
|
||||||
displays, and keycode maps for other keyboards. Also, there is no
|
|
||||||
support for hardware palettes.
|
|
||||||
|
|
||||||
There is currently no mouse support.
|
|
||||||
|
|
||||||
To compile SDL with support for wscons, use the
|
|
||||||
"--enable-video-wscons" option when running configure. I used the
|
|
||||||
following command line:
|
|
||||||
|
|
||||||
./configure --disable-oss --disable-ltdl --enable-pthread-sem \
|
|
||||||
--disable-esd --disable-arts --disable-video-aalib \
|
|
||||||
--enable-openbsdaudio --enable-video-wscons \
|
|
||||||
--prefix=/usr/local --sysconfdir=/etc
|
|
||||||
|
|
||||||
|
|
||||||
Setting the console device to use
|
|
||||||
=================================
|
|
||||||
|
|
||||||
When starting an SDL program on a wscons console, the driver uses the
|
|
||||||
current virtual terminal (usually /dev/ttyC0). To force the driver to
|
|
||||||
use a specific terminal device, set the environment variable
|
|
||||||
SDL_WSCONSDEV:
|
|
||||||
|
|
||||||
bash$ SDL_WSCONSDEV=/dev/ttyC1 ./some-sdl-program
|
|
||||||
|
|
||||||
This is especially useful when starting an SDL program from a remote
|
|
||||||
login prompt (which is great for development). If you do this, and
|
|
||||||
want to use keyboard input, you should avoid having some other program
|
|
||||||
reading from the used virtual console (i.e., do not have a getty
|
|
||||||
running).
|
|
||||||
|
|
||||||
|
|
||||||
Rotating the display
|
|
||||||
====================
|
|
||||||
|
|
||||||
The display can be rotated by the wscons SDL driver. This is useful
|
|
||||||
for the Sharp Zaurus, since the display hardware is wired so that it
|
|
||||||
is correctly rotated only when the display is folded into "PDA mode."
|
|
||||||
When using the Zaurus in "normal," or "keyboard" mode, the hardware
|
|
||||||
screen is rotated 90 degrees anti-clockwise.
|
|
||||||
|
|
||||||
To let the wscons SDL driver rotate the screen, set the environment
|
|
||||||
variable SDL_VIDEO_WSCONS_ROTATION to "CW", "CCW", or "UD", for
|
|
||||||
clockwise, counter clockwise, and upside-down rotation respectively.
|
|
||||||
"CW" makes the screen appear correct on a Sharp Zaurus SL-C3100.
|
|
||||||
|
|
||||||
When using rotation in the driver, a "shadow" frame buffer is used to
|
|
||||||
hold the intermediary display, before blitting it to the actual
|
|
||||||
hardware frame buffer. This slows down performance a bit.
|
|
||||||
|
|
||||||
For completeness, the rotation "NONE" can be specified to use a shadow
|
|
||||||
frame buffer without actually rotating. Unsetting
|
|
||||||
SDL_VIDEO_WSCONS_ROTATION, or setting it to '' turns off the shadow
|
|
||||||
frame buffer for maximum performance.
|
|
||||||
|
|
||||||
|
|
||||||
Running MAME
|
|
||||||
============
|
|
||||||
|
|
||||||
Since my main motivation for writing the driver was playing MAME on
|
|
||||||
the Zaurus, I'll give a few hints:
|
|
||||||
|
|
||||||
XMame compiles just fine under OpenBSD.
|
|
||||||
|
|
||||||
I'm not sure this is strictly necessary, but set
|
|
||||||
|
|
||||||
MY_CPU = arm
|
|
||||||
|
|
||||||
in makefile.unix, and
|
|
||||||
|
|
||||||
CFLAGS.arm = -DLSB_FIRST -DALIGN_INTS -DALIGN_SHORTS
|
|
||||||
|
|
||||||
in src/unix/unix.max
|
|
||||||
|
|
||||||
to be sure.
|
|
||||||
|
|
||||||
The latest XMame (0.101 at this writing) is a very large program.
|
|
||||||
Either tinker with the make files to compile a version without support
|
|
||||||
for all drivers, or, get an older version of XMame. My recommendation
|
|
||||||
would be 0.37b16.
|
|
||||||
|
|
||||||
When running MAME, DO NOT SET SDL_VIDEO_WSCONS_ROTATION! Performace
|
|
||||||
is MUCH better without this, and it is COMPLETELY UNNECESSARY, since
|
|
||||||
MAME can rotate the picture itself while drawing, and does so MUCH
|
|
||||||
FASTER.
|
|
||||||
|
|
||||||
Use the Xmame command line option "-ror" to rotate the picture to the
|
|
||||||
right.
|
|
||||||

||||||

||||||
Acknowledgments
|
|
||||||
===============
|
|
||||||
|
|
||||||
I studied the wsfb driver for XFree86/Xorg quite a bit before writing
|
|
||||||
this, so there ought to be some similarities.
