How to enable the gpu accelration of i.mx6q directfb gfxdriver

Hello

I use the freescale directfb-1.7-4/gfxdrivers/libdirectfb_gal.so, and put it on 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 use the gfxdrivers/libdirectfb_gal.so to 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)"

I guess it maybe go to error with the library path of libdirectfb_gal.so or other reason.

Do you meet the similar problems ?  How to solve it ?

Hi,

You need enable to gpu acceleration by modification on your menuconfig under Device Drivers > MXC support drivers >
MXC Vivante GPU support > MXC Vivante GPU support.
