  Target Milestone: ---

Hello, 

I would like to compile the image for BeagleBone Black with QT5 and SGX
(eglfs). 

My host: 
4.10.0-21-generic 
Ubuntu 17.04 x64 

I tried with branch 2017.05 and 2017.02.3: 

make beaglebone_defconfig
make menuconfig

I enabled: 
BR2_TOOLCHAIN_BUILDROOT_GLIBC
BR2_TOOLCHAIN_BUILDROOT_CXX
BR2_PACKAGE_TI_GFX
BR2_PACKAGE_TI_GFX_ES8
BR2_PACKAGE_QT5
BR2_PACKAGE_QT5BASE_EXAMPLES
BR2_PACKAGE_QT5BASE_GUI
BR2_PACKAGE_QT5BASE_EGLFS

After make I get error: 

/mnt/ssd2/buildroot/output/build/ti-gfx-5_01_01_02/GFX_Linux_KM/services4/srvkm/env/linux/osfunc.c:
In function ?pvr_dmac_inv_range?:

--- Comment #1 from Arnout Vandecappelle <arnout@mind.be> ---
As far as I know, ti-gfx is no longer supported and for recent SoCs with recent
kernels you should use ti-gfx-km (and -um). That's why beaglebone_qt5_defconfig
selects it. Is there any reason why you don't use that defconfig?

I followed the tutorial:
http://vanguardiasur.com.ar/opengl-es-on-beaglebone-black/ and I did not know
that ti-gfx is no longer supported... With (beaglebone_qt5_defconfig) ti-gfx-km
(and -um) options works! Thanks!

Could you contact the people on that site and ask them to update their page to
use the beaglebone_qt5_defconfig?
