IMX6 X11 Vivante GPU acceleration Segmentation Fault

[edward_fu]

Hi,

I am currently facing issues when trying to start X11 with Vivante GPU acceleration. This is on a custom board, using the NXP imx_4.9.123_imx8mm_ga GA Linux Kernel. I am currently using yocto warrior version and meta-freescale layer is also warrior version  :

Below is the Xorg log:

How to solve this issue ?

The issue has been fixed by xserver-xorg: Backport to fix X server 1.20.1 crash [YOCIMX-3280] · Freescale/meta-freescale@dde79e0... Please pull from warrior branch.

[edward_fu]

Nobody has ever faced this problem?

joanxie‌   Do you have any comments about my reply to you?

[joanxie]

you can refer to the 4.9.123 release note, this release version is tested for imx8mm, we never test this version for imx6, I really suggest you to use another version we tested on imx6

Embedded Linux for i.MX Applications Processors | NXP 

[edward_fu]

Do 5.4 kernel solve this IPU issue?

And what's your suggestion aoubt using yocto warriror version on imx6?

[joanxie]

we haven't released 5.4 kernel, try to uses 4.19.35(version 2.7 Warrior.) which has been tested on the imx6 board successfully:

Hi Joan,

In  warrior meta-freescale layer GitHub - Freescale/meta-freescale: Layer containing NXP hardware support metadata 

The recipes-kernel/linux directory contains the following files:

linux-fslc_5.0.bb

linux-fslc-imx-rt_4.1-2.0.x.bb

linux-imx_4.9.123.bb

linux-imx-mfgtool_4.9.123.bb

linux-qoriq_4.19.bb
linux-fslc-imx_4.9-1.0.x.bb

linux-fslc-lts-4.19.bb

linux-imx-headers_4.9.123.bb

linux-qoriq_4.14.bb

You mean I need to use linux-fslc-lts-4.19.bb? But in linux-fslc-lts-4.19.bb file kernel vesion is 4.19.78 not 4.19.35.

The content of linux-fslc-lts-4.19.bb is：

So, 

• Does 4.19.78 support X11 on imx6 board?
• As you suggested 4.19.35, which repository should I use still freescale official git hub(GitHub - Freescale/meta-freescale: Layer containing NXP hardware support metadata )?

Thanks

[joanxie]

1)Does 4.19.78 support X11 on imx6 board?

> we don't have this version bsp for imx6, for 4.19.35, yes, support x11 for imx62)As you suggested 4.19.35, which repository should I use still freescale official git hub(GitHub - Freescale/meta-freescale: Layer containing NXP hardware support metadata )?

> for 4.19.35, you can build the bsp as attached document metions

$ DISTRO=fsl-imx-x11 MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11
$ bitbake imx-image-multimedia

this is x11 for imx6q board

[joanxie]

since you use imx6 board, why did you use imx_4.9.123_imx8mm_ga  which is demo image for imx8MM board, did you try the image for imx6 boards?

[edward_fu]

Thanks for your reply. 

Yes I am using imx6 board.

Because I need to upgrade yocto version from pyro to warrior, and In Freescale github, the warrior version linux-imx recipe is as below:

I think it is OK because you can see COMPATIBLE_MACHINE = "(mx6|mx7|mx8)"
