Yes, The Mobile chipsets could do this under several circumstances. The desktop chips cannot.
Could you provide an indication of what such a feature is actually useful for? It seems like more of a "toy" feature than something with real world applications. Seems like you could actually run at 24bpp and convert from 8 to 24 in the driver with less performance impact than running an additional display plane that consumes width*height*depth*refresh bytes per second guaranteed. -Matt -----Original Message----- From: Dr Andrew C Aitchison [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2003 5:09 AM To: [EMAIL PROTECTED] Subject: Hardware overlays (8+24?) on Intel i830 I see from http://www.xig.com/Pages/PrReleases/PRMay03-830-O'lays.pdf that hardware overlays (possibly similar to what we currently do in the mga and glint drivers) are possible on the Intel i830 chipset. Does anyone know anything more, or is anyone actually working on adding support to our drivers ? If anyone with a suitable machine is interested in testing for me, and I can get chip-level details, I *might* be interested in writing the code myself. -- Dr. Andrew C.
