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. - - --- -Staffan Ulfberg <staffan@ulfberg.se>
