kernel-module-imx-gpu-viv's Issues

What does it mean by "This module is only meant for NXP-based kernel up to 4.1.x" ?

Hi,
I'm using Linux kernel version 4.9.144 which is based on toradex_4.9-2.3.x-imx and with this module "kernel-module-imx-gpu-viv" activated within Buildroot, the galcore module is automatically disabled from the kernel's menuconfig (which is enabled by default) and it is not compiled nor generated.

Also I saw that "This module is only meant for NXP-based kernel up to 4.1.x." , I'd like to know how would I get the galcore compiled for the kernel version : 4.9.144, please ?

Moreover, from this link https://boundarydevices.com/customizing-ubuntudebian-kernels/, it is said that for kernel version is 4.1.15 or higher, galcore module has to be built externally and independently to the kernel. Could you confirm, please ?

Best regards,
Khang

Usage of kernel-module-imx-gpu-viv with 3.14.79 vanilla kernel

Hi,

While trying to compile kernel-module-imx-gpu-viv with 3.14.79 vanilla kernel I am getting an error of missing header files busfreq.imx.h. Is there any other alternative to load the drivers with 3.14.79 vanilla kernel? Or I need to redo all the patches done by freescale?

cross-compilation is failing

Hi. I tried to cross-compile this module with gcc-linaro-7.4.1-2019.02-i686_arm-linux-gnueabihf and process was failed with:

panic in gckKERNEL_CreateProcessDB

Hello!

It's need to remove database from hash after gckKERNEL_DeinitDatabase()
call in gckKERNEL_CreateProcessDB(). In other case it could be found in
hash after another call of gckKERNEL_CreateProcessDB() and the kernel
will go to panic() while gckOS_AtomIncrement() call.

This bug was found with sress-ng test:
./stress-ng --dev-file /dev/galcore --dev 0

Compiling and Booting on SabreSd with Android Lollipop L5.1.1_2.1.0-ga

Hi Sir,

We are facing 1080p60 video performance issue with the Freescale Sabre SD board running Android Lollipop L5.1.1_2.1.0-ga release. Attached are the Systrace logs captured from prebuilt images, with playing video( lp_good.html) and video+ pulling notification bar (lp_bad.html)

more info of problem are here link

After the bug been reported here, we wanted to try the new GPU 5.0.11p8 driver.

I tried to compile and integrate the freescale gpu driver with the Android Lollipop L5.1.1_2.1.0-ga release.
But I am getting crashes below

Looks like the update libEGL_VIVANTE.so, libGAL.so is needed.

Can you give me some inputs to resolve this.

File descriptor leak on imx-gpu-viv drivers

Hello,

I'm facing this issue with wpe-webkit Igalia/cog#87
I'm building for i.MX 8MQuad using thud branch, the fdo backend and the core-image-weston image

Is this an imx-gpu-viv issue ?

Source of NPU Part

Hello, is it possible to have source code with NPU? Some vivante gpu implementations like the one in RK1808 does have NPU

I'm trying to build it and having this build issue:

Does KERNEL_SRC needs to be defined before?
