We are using sensoray > video module, which uses Lynx3DM chip. The framebuffer driver as a whole is incomplete, and won't work as a frame buffer driver. If someone were to correct that, that would be a Good Thing (tm). I wrote the driver for use on the Embedded Planet Icebox (Sensoray 322 module). I was primarily using the XFree86 siliconmotion driver, but this makes some PCish assumptions. I wrote the framebuffer driver to do the basic initialization of the card - with the fb driver loaded it's relatively easy to get X working. I intended to complete it - i.e. make it a fully working fb driver, but I never had the time. Note that the fb driver does do one particularly important thing - it initializes the memory subsystem using some undocumented prodding of the card. On PCs this is performed by the card BIOS, and the video memory won't work correctly without it. -- David Gibson | For every complex problem there is a david@gibson.dropbear.id.au | solution which is simple, neat and | wrong. http://www.ozlabs.org/people/dgibson ** Sent via the linuxppc-embedded mail list.
