[Linux-fbdev-users] Hardware acceleration in frame buffer driver

[<dam...@fr...>]

Hello,

I am trying to implement hardware acceleration to a framebuffer driver, t=
hrought
the functions fb_fillrect, fb_copyarea and fb_imageblit. So I replace the
cfb_fillrect functions by my own, and add FBINFO_HWACCEL_FILLRECT to
fb_info->flags. But I try to use both embbeded/QT and Nano-X, and these
hardware accelerated functions are never called.

I did a lot of research but probably missed someting... I do not understa=
nd why
these "needed" functions are never called ?

Thank you

Unfortunately, these accelerated functions are for the console use only.  No
other app can use this functions.
