Hi ,
I'm involved in a Directfb+QT embedded project using a platform with a
XGI Volari Z9s graphics chip. The prototype is up and running within a
pair of work days, but the performance is disappointing. I think the
problem comes from various places, but one of my concerns is the quality
of the SiS315 driver included with Directfb (I've already discovered a
bug wich prevents from rectangle fill,rectangle,and line from being HW
accelerated. So, in order to improve this driver, I've been googling for
some kind of programmers guide describing IOCTLs (maybe from from
SiS/XGI), but the only source of information I have found are Xorg
drivers source code and a webpage from the author of the drivers. Does
anyone knows where can this guide be obtained?
Best regards,
Pablo.
