imx6 Android gpu 内存,Use vivante GPU on IMX6 with 4.14 kernel

I am working on IMX6QP with yocto rocko / Linux 4.14.24 and I am trying to use the GPU.

My yocto configuration file :

MACHINE ??= 'imx6qp-tx6-emmc'

DISTRO_FEATURES_append = " opengles2 egl opengl gles gbm dri eglfs gles2 "

BB_NUMBER_THREADS = "1"

LICENSE_FLAGS_WHITELIST = "commercial"

When I run es2gears or Qt5_CinematicExperience yocto displays this :

gbm: failed to open any driver (search paths /usr/lib/dri)

gbm: Last dlopen error: /usr/lib/dri/etnaviv_dri.so: cannot open shared object file: No such file or directory

failed to load driver: etnaviv

gbm: failed to open any driver (search paths /usr/lib/dri)

gbm: Last dlopen error: /usr/lib/dri/kms_swrast_dri.so: cannot open shared object file: No such file or directory

failed to load driver: kms_swrast

Unable to create EGL surface (eglError: 12299)

In the /usr/lib/dri folder there is only : swrast_dri.so

How can use the vivante GPU with this kernel? Is it possible?

Where can I find the etnaviv driver without include meta-freescale layer?

The goal will be to run a Qt5 application that use eglfs.

In the file meta-karo/conf/machine/include/tx-base.inc :

PREFERRED_PROVIDER_virtual/egl ?= "mesa"

PREFERRED_PROVIDER_virtual/libgles1 ?= "mesa"

PREFERRED_PROVIDER_virtual/libgles2 ?= "mesa"

PREFERRED_PROVIDER_virtual/libgl ?= "mesa"

PREFERRED_PROVIDER_virtual/libg2d_mx6 ?= "mesa"

PREFERRED_PROVIDER_virtual/libg2d_mx6ul ?= ""

I added :

CORE_IMAGE_INSTALL += "imx-gpu-viv"

in local.conf and the console displays :

ERROR: Nothing RPROVIDES 'imx-gpu-viv' (but /media/user/tx6qp-qt5-4.14/build/sources/poky/meta/recipes-core/images/core-image-minimal.bb RDEPENDS on or otherwise requires it)

imx-gpu-viv was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not imx-gpu-viv

NOTE: Runtime target 'imx-gpu-viv' is unbuildable, removing...

Missing or unbuildable dependency chain was: ['imx-gpu-viv']

NOTE: Target 'core-image-minimal' is unbuildable, removing...

Missing or unbuildable dependency chain was: ['core-image-minimal', 'imx-gpu-viv']

ERROR: Required build target 'core-image-minimal' has no buildable providers.

Missing or unbuildable dependency chain was: ['core-image-minimal', 'imx-gpu-viv']

And my kernel supports CONFIG_DRM_ETNAVIV

My board is a Karo board bought on this page.

Thanks in advance,
