[Linux-fbdev-users] Basic hw operations

[Antonio N. <an...@ie...>]

Hi all,

as a user of a fb driver I would like to write an application which 
scales an image from its original size to the screen size. To do so I'd 
like to make use of the hw acceleration capabilities of my card. At the 
moment I can mmap the hw engine getting access to the registers, but 
unfortunately I don't know the behaviour of the basic hw operations. 
I've been googling a lot but I'm not able to find the appropiate document.

I would appreciate if someone could give a hint in this sense. Does 
anyone know any good ebook or howto? What I need is a general document.

By the way, I'm using viafb from viaarena and the card is a VIA CN700.

Thanks a lot!

Antonio
