How to use the VIV GPU vprovfiler?

liangluo — Mon, 28 Oct 2013 06:21:39 GMT

I followed the guide of vprovfiler,

modify the configure file of GPU driver.

USE_POWER_MANAGEMENT = 0

USE_PROFILER = 1

Extract the pre-built binaries (enable the profile) and replace the libraries

But when I execute the open GLES application, the application crashed, and failure log is: segmentation fault!

Please clarify which release are you using?

Which backend are you using?

And which application are you using for test?

Thanks.

Are you using default ltib rootfs?

And please double check if your vdk version is 1.4.5.

Can the Modified kernel co-work is standard rootfs?

Thanks.

It should be shown at the VDK package name.

Unfortunately, I didn't find the version at the package name, the package is downloaded from https://www.freescale.com/webapp/Download?colCode=I.MX_6DL_S_VIVANTE_VDK_TOOLS&appType=license&location=null&fsrch=1&sr=6&Parent_nodeId=from%20search&Parent_pageType=from%20search&Parent_nodeId=from%20search&Parent_pageType=from%20search and our soc is imx6solo.

In the package, it shows the vdk tools is for 3.0.0 release. "Linux L3.0.35_3.0.0 GPU Driver with vprofiler"

Please use the correct vdk tool package for 4.0.0 release.

Hello,

I have the same problem about the vprofiler , when I execute the openGLES application (opt/viv_samples/vdk), the application crashed : segmentation fault :smileyblush:

I use Kernel 3.0.35 from L3.0.35_4.1.0_130816_source (LTIB).
My board = imx6 sabrelite

Have you got a tarball of system with the integrated profiler ?

Regards,

Hi ,

I downloaded the Kernel 3.0.35 adn the VDK tools from i.MX 6 Q/D/DL/S L3.0.35_4.1.0 GA release .

After that I modified the configure file of GPU driver:-

USE_POWER_MANAGEMENT = 0

USE_PROFILER = 1

Then i extracted the pre-built binaries (enable the profile) and replace the libraries.

Then as mentioned in the readme file executed the ./ltib command to build.

But now when i am running any OpeGLES application I am getting a Segmentation Fault.

Can somebody please help here?
