TrollTech uses the Linux framebuffer and does not have acceleration support except for a small number of sample drivers (Mach64, Matrox and Voodoo3). Hence if Qt works on that device, it just uses a dumb framebuffer and whatever is exported by the kernel via the framebuffer interface.

In the general computing world, the vendor has to worry about both OEM sales and retail sales. In the embedded world, you ONLY have OEM sales. You cannot go out and buy an Imageon 100 add-in card for your Zaurus, so there is even less incentive for the chip vendor to provide any public support. Their consumer is the OEM. If the OEM is happy, ATI is happy. -- - Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

ATI Imageon 100
Hi all! This is not yet XFree86 related but hopefully will be :) I am looking for a good contact to ATI for information about their embedded graphics controller IMAGEON 100. This one is used in some Casio and especially the new Sharp PDAs (Zaurus CL-700, 750 and 760). We want to write an accelerated XFree86 driver for it so that handhelds.org Linux using X11 and GPE could run more efficiently on it. Currently there is only an undocumented Linux kernel framebuffer driver which is quite slow. Using the acceleration features of the chip we should be able to get decent performance and nice features like hardware accelrated rotation and even MPEG acceleration. Without we get a crawlingly slow desktop :( Main target machine would be at first the Zaurus CL-7xx machines but not limited to them. Higher resolution screens slowly become a standard and thus the need for a decent driver will become more urgent on other embedded XFree86 capable platforms too. So please if anyone from ATI is listening, please consider to support an XFree86 driver development! If your are interested, please write to this list or email me. If none is listening but someone who knows someone at ATI who could be of help, please speak up! If there is someone who knows anything else that there is to know about such a development, ... please say so too, of course. Many thanks in advance!
