Get kernel error when initiating SGX driver on AM3517.

Can you baseline your environment per below script and send the output ?

http://processors.wiki.ti.com/index.php/SGXDbg#Baselining_the_current_SGX_driver_environment

Hi,

This is the output from the script. But not that this is before executing the rc.pvr as this will start pvrsrvinit which makes the kernel crash.

This error happens if the SGX module is not enabled and a write happens. From the logs, the omap-demo script has not been run. The SGX module is initialised explicitly at the start of this file (<GFX_SDK>/targetfs/omap-demo). This should be followed.

Hi,

I can't use the omap-demo script on my board as I have a read only file system. I thought the omap-demo script only read the SGX module revision and then executed the insall.sh script. The install.sh script copies the binaries from the /opt/gfxlibraries/ to their appropriate place on the target. But as I have a read only file system I have written my own install.sh that fits into my other build scripts. My custom install.sh does the same work as the original but on my host system. So when I start my board I already have all binaries on the correct place. Therefore I only execute the rc.pvr (PowerVR SGX DDK for Embedded Linux - installation script) at startup of the system.

But it's now when I execute the rc.pvr script I get the kernel error which makes the kernel crash.

Hope this gave you some insight into my system setup

Okay so the omap-demo starts the SGX module, is it the devmem2 commands in the beginning of the file you are referring to that does this?

/etc/init.d/devmem2 0x48004B48 w 0x2
/etc/init.d/devmem2 0x48004B10 w 0x1
/etc/init.d/devmem2 0x48004B00 w 0x2
/etc/init.d/devmem2 0x50000014 > /etc/init.d/sgxrevision.txt

I have now added the devmem2 commands the beginning of the rc.pvr script. This should do the same as if the omap-demo script was executed. But I still get the same error as before below is the log output and you can see the devmem2 commands in the beginning.

Hi,

I have done some more investigations in the pvrsrvkm kernel module and managed to get the rc.pvr script to run without a kernel crash.

Basically what I did was to remove the register write that I suspected was the error in my first post. In the file sgxinit.c we have the function SGXInitialise() which is called when the pvrsrvinit is executed. In the SGXInitialise() there is a register write see below:

if(!cpu_is_omap3530())
{
              OSWriteHWReg(psDevInfo->pvRegsBaseKM, 0xFF08, 0x80000000);//OCP Bypass mode

}

It’s this register write that causes the kernel to crash. So I removed this and now the system boots successfully see log below. I can now run the sdk demo programs like OGLESParticles etc. The program is running and displayed on the screen, but I get some warning and one error see output below. You can also see the output from the baseline script below.

So my question is now if I need to configure something more to remove the errors from the OGLESParticles demo?

The modification done is correct. This is fixed in the current version of the Graphics SDK (4.05.00.03) (http://tigraphics.blogspot.com/2011/12/final-4q-graphics-sdk-package-4050003.html) that has some additional fixes. It is advised to move to this version.

The messages output are ok.
