Thanks for the tip, I hadn't heard about it. I will take a look, but only to see if it can show me the user space API of /dev/fb. I don't need a general library that supports a bunch of different graphics cards. I'm writing my own frame buffer driver for the GX2 CPU, and I just want to know how to call the various functions registered in struct fb_ops, so that I can test my code. I mean, all those functions registered in fb_ops must be accessible somehow; if they weren't, what purpose would they serve? -- Haakon - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
