[fulinux]

Hi, i am proting imx-gpu-viv-5.0.11.p8.3-hfp for my imx6q board, my bsp tag is rel_imx_4.1.15_1.0.0_ga, i have not use yocto, because it is too big to down for a foreigner. i just  git clone one by one. i get imx-gpu-viv-5.0.11.p8.3-hfp, and add it's lib to my rootfs, and i run gpu-demos:

1、

# cd es20/vv_launcher/

# ls

vv_launcher

# ./vv_launcher

-sh: ./vv_launcher: not found

# /lib/ld-linux.so.3 ./vv_launcher

/* nothing happens */

2、

# cd viv_samples/tiger/

# ls

tiger

# /lib/ld-linux.so.3 ./tiger

vdkIntialize() failed.

CreateWindow() failed.

3、

# cd g2d/

# ls

g2d_test      overlay_test

# ./g2d_test

-sh: ./g2d_test: not found

# /lib/ld-linux.so.3 ./g2d_test

/* it has a picture on screen */

my Qt programs can't run,look like as follows, what is wrong?

# ./qmlscene

QEglFSImx6Hooks will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.

If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

Unable to query physical screen size, defaulting to 100 dpi.

To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

QEGLPlatformContext::init: eglError: 3005, this: 0x3e2e80

can you give me some ideas, what happened? i am a new hand.

thank you!

Hi fulinux

adding just lib to rootfs is not sufficient, also it is necessary to build gpu kernel

drivers, for details please refer to attached Linux Manual sect.13.1.1.2 Software Operation

Best regards

hi,

I did as you told me:

To get to the GPU library package in Yocto, use the command  bitbake linux-imx -c

menuconfig . On the screen displayed, select Configure the kernel and select "Device

Drivers" > "MXC support drivers" > "MXC Vivante GPU support" > "MXC Vivante

GPU support"and exit. When the next screen appears select the following options to

enable the GPU driver:

• Package list > gpu-viv-bin-mx6q

• This package provides proprietary binary libraries, and test code built from the GPU

for framebuffer

i had enabled "<*> MXC Vivante GPU support", but when i exited the next screen don't appears select the following optiongs to enable the GPU driver,

i git clone linux-imx.git, then:

make imx_v7_defconfig

make menuconfig

i don't use fsl-release-bsp, is it have to use bitbake linux-imx -c menuconfig?

Dear igor,

if i use gcc-4.7 to compile kernel and Qt5.4,  soft float point, can i use imx-gpu-viv-5.0.11.p8.3-hfp lib
