Hello,
How to I configure directfb to enable GPU acceleration of blitting and compositing operations?
Thanks,
Chuck
Solved! Go to Solution.
Freescale i.MX6 BSP by default enables the DirectFB 1.4.0 GPU acceleration. To makesure, check the $(ROOTFS)/usr/lib/directfb-1.4-0/gfxdrivers/libdirectfb_gal.so is present and run df_dok benchmark application from DirectFB-examples to see the difference.

Hello
I use the freescale directfb-1.7-4/gfxdrivers/libdirectfb_gal.so, and I also put it in the path of $(ROOTFS)/usr/lib/directfb-1.7-4/gfxdrivers/libdirectfb_gal.so,when I execute ./df_dok --accelonly,there is not picture on the screen, and the start infomation of DirectFB-example-1.2.0 is " Directfb/Graphics: Generic Sofeware Rasteriser 0.7 (directfb.org) ", I know it dosen't use the gpu of Vivante. When I execute ./df_dok, there are pictures on the screen.
How can I enable the gpu accelration of Vivante ?
I see a Netizen enable the directfb gpu acceleration, and the start infomation of DirectFB as follows :
"DirectFB/Graphics: Vivante unknown chip model 1.0 (Vivante)"
Where is the wrong ? Waiting for help!
Thank you!
Does the same library works for DirectFB v 1.6.0 ?
I use project yocto with version dylan, use the directfb v1.6.1 also, so....
Does the same library works for DirectFB v 1.6.1 ?
Yes it does work, even with directfb-1.6.3, but you have to make some link to make libdirectfb_gal.so workable :
ln -s /usr/lib/libdirectfb-1.6.so.0.3.0 /usr/lib/libdirectfb-1.4.so.0
ln -s /usr/lib/directfb-1.4-0/gfxdrivers /usr/lib/directfb-1.6-0/
But it does not work with directfb-1.7.0 :smileycry:
Is there an answer to this question?
