Hello,
I found that there's no information about howto build directfb with PVR2D system support
with Ti omap proccessors.
I downloaded Ti's gfx SDK, and built the gles2 gfx driver and make the kernel module and service ready.
Then I just copied pvr2d.h and wsegl.h into gfxdrivers/pvr2d. and set the LDFLAGS to link with libpvr2d, libGLESv2 libEGL.
configured directfb and enabled pvr2d system and pvr2d,omap,gles2 gfxdirvers. and when I just configured system=pvr2d in directfbrc
and run the df_dok demo.
there's some err:

And the screen displays unrecognized things.
BUT if I don't set the system in directfbrc and leave it self-probing.
the dfb will use frambuffer and everything is ok with this benchmark:

So, My problem is there maybe something wrong with my building with dfb or my omap linux cmdline with video configration was wrong.
====
# cat /proc/cmdline
console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait vram=64M omapfb.mode=dvi:1024x768MR-16@60 omapfb.video_mode=dvi:1024x768MR-16@60 omapdss.def_disp=dvi omap-dss.def_disp=dvi
