cubox-i kernel-module-imx-gpu-viv compilatin issue

cubox-i kernel-module-imx-gpu-viv compilatin issue

[Piotr Król]

Hi all,
I'm following this instructions to build cubox-i multimedia image:

mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo >
~/bin/repo
chmod a+x ~/bin/repo
PATH=${PATH}:~/bin
mkdir fsl-community-bsp
cd fsl-community-bsp
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b
krogoth
repo sync

. ./setup-environment build

Then set MACHINE ?= 'cubox-i' in build/conf/local.conf and run:

bitbake fsl-image-multimedia

In results I get kernel-module-imx-gpu-viv compilation error:

gc_hal_kernel_platform_imx6q14.c:81:31: fatal error: linux/busfreq-imx.h: No such file or directory

(...)

gc_hal_kernel_os.c:5871:5: error: implicit declaration of function 'dmac_map_area'

Full log [1]. Anyone experienced that issue ? I saw some posts about
that [2][3], but those address issue in older kernels and default for
cubox-i is 4.4.

From what I understand functions like dmac_map_area should not be used
directly, but through dma-mapping API ie. arm_dma_map_sg or even
arm_dma_sync_sg_for_cpu, arm_dma_sync_sg_for_device. Is that correct
understanding ?

Does kernel-module-imx-gpu-viv requires some major rewrite ?

If yes then how multimedia image ie. with VPU support can be built using
meta-freescale ?

This is because CuBox does not use the i.MX kernel and thus does not
offer the GPU support.

cubox-i is not fully supported in meta-fsl-arm-extra anymore. You are 
limited to the FSLC kernel with it. See 
https://github.com/Freescale/meta-fsl-arm-extra/blob/master/conf/machine/cubox-i.conf#L17 
.

For full support, you need to contact SolidRun.

Hi Carlos, Otavio,
thanks for your answers. I'm trying to utilize this process for
HummingBoard and documentation say that I should use cubox-i machine
configuration.

Maybe it is possible to fix stuff so fsl-image-multimedia and
fsl-image-multimedia-full will not build for cubox-i machine or build
only with FSLC kernel, so other people will not have problems with that
board ? Any way I can help with that ?

What I'm trying to achieve is to test VPU with mainline kernel by
playing couple video files. Ultimately I would like to try Qt WebEngine
with HTML5 video content, but I assume this may be no so straight
forward path. Is it possible with meta-freescale or I should take other
approach ?

What is missing in this cubox-i to support HummingBoard platform ?


Any advise how to try hardware decoding with mainline would be
appreciated.
