Porting GPU libraries for any Linux-base X11 root filesystem

[mayqueen]

Kernel version: 3.10.53-ga

I porting VPU libraries success for ubuntu 14.04 LTS (LXDE desktop) yesterday,

but I have no idea to porting GPU libraries using yocto.

because I trace VPU relative files for yocto, and I don't know how to trace GPU,

Could Anyone help me?? give me some direction or comment, thanks so much!

Sorry my CPU was IMX6Q

Hi May

I would suggest to look at GPU docs in Linux Bundle

L3.14.28_1.0.0_iMX6QDLS_BUNDLE : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite,

i.MX 6Solo Linux Binary Demo Files and Linux BSP Documentation

Note, gpu are closed-source libraries, starting with 3.10.53 gpu have

support via kernel loadable modules to support  both 3.10.53 and 3.14.28 kernels.

Best regards

igor

Thank you Igor:

I trying to porting pre-built binary files in ubuntu-armhf 14.04 from yocto using "xserver-xorg-video-imx-viv-3.10.53-1.1.0" folder yesterday,

but when I load these libraries, the Xorg log shows error message as below:

[	18.562] Loading extension GLX
[	18.562] (II) LoadModule: "vivante"
[	18.568] (II) Loading /usr/lib/xorg/modules/drivers/vivante_drv.so
[	18.604] (II) Module vivante: vendor="X.Org Foundation"
[	18.604]	compiled for 1.16.1, module version = 1.0.0
[	18.604]	Module class: X.Org Video Driver
[	18.604]	ABI class: X.Org Video Driver, version 18.0
[	18.604] (EE) module ABI major version (18) doesn't match the server's version (15)

[	18.604] (II) UnloadModule: "vivante"
[	18.604] (II) Unloading vivante

How to get the correct ABI version for vivante_dri library?? Maybe I missing something else??

Thanks for your help!

Hi May

I would suggest post this to meta-fsl-arm mailing list, so that someone

familiar with similar issues could try to assist you.

Thanks! so GPU libraries depend on kernel version, right? because the VPU libraries has no dependent problem...

from 3.10.53 kernel - not, since starting with 3.10.53 gpu have

support via kernel loadable modules to support  both 3.10.53 and 3.14.28 kernels.
