Hello,
i need to profile the GPU on an IMX6 Board. For this i got the hint to use the Vivante VDK Tools.
I build the BSP from the wiki.Wandboard.org repo init -u https://github.com/Freescale/fsl-community-bsp-platform .
I downloaded the Vivante VDK v1.4.6 and i wanted to follow the readme.txt.
Now i have to replace the libs from the Vivante Bundle, but i exactly dont know how to.
And then the Kernel source code from the gpu driver should should be modified, but i dont kwno where i can find these files in the Yocto Project because the guide is explained how to use this for Ltib.
Have any of you got this working? I'd be most grateful for any comments / suggestions.
Hi,
I know that this post is old but I followed i.MX_Graphics_User's_Guide.pdf seccion 7.6.2 in order to get the vProfiler and
vAnalyzer to work. I am using a i.MX6D. You have to enable the profiler at the kernel level. As someone mentioned there are several ways to do that. I used the U-Boot method, passing a kernel parameter through bootcmd:
In my case I used the following commands to achieve that:
U-boot>
Noticed that I just added galcore.gpuProfiler=1 to my current bootcmd variable.
You can confirmed if it worked using the following command from the shell:
cat /sys/module/galcore/parameters/gpuProfiler
if you get a 1, it worked.
Then you have to export the following env vars in the current session. In this case it is a X11 session, since I am going to profile an opengl application:
Finally you just have to run the application and the driver will create a file called sample.vpd in the running directory.

Hi,
In case anyone does set =1 in kernel 4.1.15 bootparams and gpuProfiler does not get enabled (you get an empty vpd file), you can try replacing the value with the hex version of it, then also add showArgs, which will printout a debug message in dmesg while booting:
galcore.gpuProfiler=0x1 galcore.showArgs=0x1
eg:
[ 2.009390] Galcore version 5.0.11.41671
[ 2.015418] Galcore options:
[ 2.021366] irqLine = 310

[ 2.035534] registerMemSize = 0x00004000
[ 2.039851] irqLine2D = 311
[ 2.043522] registerMemBase2D = 0x00134000
[ 2.047869] registerMemSize2D = 0x00004000
[ 2.052161] contiguousSize = 134217728
[ 2.056395] contiguousBase = 0x00000000

[ 2.106090] recovery = 1
[ 2.109584] stuckDump = 0
[ 2.113076] gpuProfiler = 1
to confirm gpuProfiler variable was set to 1 and should be enabled.
Thank you all for writing all the information in this public thread, since I couldn't have done it without your help !
Best regards, Gabriel
Bio_TICFSL, Can you please comment?
It has been two months since the question is posted.
May I know is there any update regarding the Vivante GPU profiling issue?
Hi Kim,
Please try to use the latest Linux BSP version. When building Vivante Graphics Drivers in a Linux environment, the driver is built with vProfiler capability.
To activate vProfiler functionality, there are two ways to do it:
1. we only need to add a sentence "galcore.gpuProfiler=1" in the attribute of bootargs in your boot configuration. For example, if use the nfs to boot the linux, we can configuration boot like: setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp video=mxcepdcfb:E060SCM,bpp=16 max17135:pass=2,vcom=-2030000 galcore.gpuProfiler=1'.
2. Use the command line to add the gpuProfiler=1 option, or add the option into an existing .sh script similar to the following:
#!/bin/bash
#
insmod /lib/modules/galcore.ko gpuProfiler=1 [OPTIONS]
chmod 777 /dev/galcore
Note: The path before file galcore.ko need not to reference this path, it is the path where your .ko file puts.
Hope this helps
i found that /dev/galcore is already there after i booted into my mx6 Linux BSP with or without the galcore.gpuProfiler=1.
anyway, i still configure my bootargs as follow:
setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 init=/init rootwait galcore.gpuProfiler=1'
after boot into the rootfs,i configure my environment variables as follow:
export VPROFILER_OUTPUT = sample.vpd
export VPROFILER_FRAME_NUM =100
export VPROFILER_SYNC_MODE=1
I CANT find any sample.vpd created in my directory after I run an GLES2.0 application as provided by Vivante' GPU SDK (e.g. 02_ColoredTriangle).
Any help?
Hi Kim,
I also had trouble getting the GPU profiler run.
I suggest you download this (functional) Image : backup_vProfiler.gz - Google Drive
In order to test this image, here are some commands :
1) sudo gzip -dc /path/to/backup_vProfiler.gz | dd of=/dev/sdX
2) run script in /opt
- . ./profiler.sh
3) export VIV_PROFILE=1
4) run your application
5) put the vpd file into vAnalyser
This is a custom distribution (LTIB)
Help :

Pierre-Jean TEXIER
Pierre, thanks for your useful help.
I downloaded your image and found that it can't be booted.

May I know where i can obtain the linux kernel you used to boot the rootfs you have uploaded?
i managed to load the kernel after configuring uboot with the correct boot arguments
setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw'
setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc dev 0; ext2load mmc 0:1 0x10800000 /boot/uImage; bootm'
however, it stuck at 'Waiting for root device /dev/mmcblk1p1...'
the complete boot log is as follow:
MX6Q ROM-3420 U-Boot > setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw'
MX6Q ROM-3420 U-Boot > setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc dev 0; ext2load mmc 0:1 0x10800000 /boot/uImage; bootm'

Waiting for root device /dev/mmcblk1p1...
Hi,
Maybe try to change "root=/dev/mmcblk1p1" by root=/dev/mmcblk0p1.
Regards
Pierre-jean
i dd your image into an SDcard (/dev/mmcblk1p1). root=/dev/mmcblk0p1 will boot into my MX6' onboard rootfs.
Not use dd try with this command : sudo gzip -dc backup_vProfiler.gz | dd of=/dev/sdX , unzip directly on the SD Card.
Regards
Thanks Pierre.
I think my approach should be the same with yours as I dd the result of gunzip backup_vProfiler.gz to of=/dev/sdX
Maybe yes, but I'm sure my command work :smileywink:
Keep me informed of your progress
