IMX6D: Unable to load galcore module with NXP Linux Kernel 4.14.98-2.0.0-r0

[npatel]

Hello all,

Using the 4.14.98-2.0.0-r0 NXP Linux Kernel on an custom IMX6D based board, the galcore driver fails to load during boot:

.

.

.

[    4.591424] galcore: loading out-of-tree module taints kernel.

.

.

[    4.616583] galcore: probe of 130000.gpu failed with error -22

When I manually insmod galcore.ko, more information is displayed:

# insmod galcore.ko

[     3] Failed to open device: No such file or directory, Try again...
[     4] Failed to open device: No such file or directory, Try again...
[     5] _OpenDevice(1229): FATAL: Failed to open device, errno=No such file or directory.

I'm assuming the gmem_info command failure happens due /dev/galcore not being created.

Has anyone encountered this issue with the galcore driver with a newer NXP Linux Kernel? Is there a work around/fix?Any help/suggestions would be very much appreciated!

Thanks,

Hi Bio_TICFSL,

Which imx-gpu-viv library binary should be used with the galcore driver from the 4.9.88 NXP imx kernel? I'm trying use the vivante fb with X11, but I'm encountering a segfault during X11 startup. Here is what my Xorg log file looks like:

Hello,

It has not an issue with 4.14.98 Linux kernel, however since you are using MX6D we recommend to use the 4.9.88 is the last for MX6D, the 4.14.98 is more for MX8.

However we are trying to reproduce your issue without success the galcore run normal

Regards

Hi Bio_TICFSL,

Would you be able to provide the gpu node entries in the device tree for the IMX6D/IMX6Q? I want to verify if that may be causing the problem of the galcore driver not loading properly.

I appreciate your help!

Thanks,

Neil

Hi Bio_TICFSL,

Using the galcore driver from the 4.9.88 imx kernel did the trick! Now I can also run the gmem_info utility as well (used to either crash the galcore driver or couldn't open the /dev/galcore device):

root@imx:/dev# gmem_info

Thank you very much for your help!

Hi,

I am using kernel 4.14.174 with yocto Sumo revision.

My galcore is 6.2.4 and i am using qt5 for my HMI

As soon as i run HMI , it gets crashed.

the log of backtrace looks like:

Hello Bio_TICFSL,

Can you confirm whether there is an issue with the vivante driver in the 4.14.98 NXP Linux kernel?

Thanks,

Neil

[npatel]

Using the galcore driver from kernel-module-imx-gpu-viv_6.2.4.p4.0.bb kernel-module-imx-gpu-viv_6.2.4.p4.0.bb, in which the SRCBRANCH is the same 4.14.98_2.0.0 linux kernel, the driver crashes when manually loaded:

Hello Neil,

It appears that galcore compiled for other kernel version, however please download again the whole bsp.

Regards

[npatel]

Hi Bio_TICFSL,

I've rebuilt my image from scratch, re-downloading the BSP and still got the same error. Can you also tell me what the galcore error flags are?

I.e.:

galcore: probe of 130000.gpu failed with error -22

What is error -22?

Thanks,

Neil

[hiteshviradiya]

Hi Neil,

I am facing similar error, how did you resolve it ?

--

Thanks,

Hitesh

[npatel]

Hi Bio_TICFSL,

I'll try doing a clean build in yocto and let you know how that goes.

Thanks,

Neil
