hi ，I need to run a qt gpu application in AM3359
I've set up the environment, the details are as follows:

kernel and pvr km: build from ti-processor-sdk-linux-rt-am335x-evm-04.03.00.05 and the lcd display is well

filesystem with pvr um: use rootfs build from tisdk with configuation "processor-sdk-04.01.00.06-x11-config"

when i run my gpu app, the error message is as follows:

PVR():SGXKickTA:TA out of Mem and SPM occurred during last TA kick [0, ]

What does that mean and how can it be fixed?

Hello,

Could you please try increasing the parameter buffer size, here is an example:

root@am57xx-evm:~# cat /etc/powervr.ini

[default]

ParamBufferSize=64000000

MaxParamBufferSize=64000000

Regards,

hello

I added the file powervr.ini as follows

[default]
ParamBufferSize=64000000
MaxParamBufferSize=64000000

when i run my gpu app, another error message is as follows:

root@am335x-evm:/userfs/app/Robot# ./RobotSimulation -platform xcb
xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb
Qt: Failed to create XKB context!
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ':' as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see cgit.freedesktop.org/.../ .
PVR:(Error): FindAppHintInFile : Reached end of file too early in /etc/powervr.ini line 3 [0, ]
m_vertsArray[ 0 ].size= 176886
m_colorsArray[ 0 ].size= 176886
m_normalsArray[ 0 ].size= 176886

Does that mean my file format is wrong？

Hello,

Could you share your powervr.ini file because I do not see the same error on my test setup?
