Has the SGX clock been enabled ? Has the /etc/init.d/omap-demo init script been run before running the driver ?
Note: Post the output of below Script, while posting queries related to SGX drivers:

we use openembedded which includes this startup script (runs after boot):
http://arago-project.org/git/?p=arago.git;a=blob_plain;f=recipes/powervr-drivers/libgles-omap3/rc.pvr;hb=HEAD
in the mean time i managed to compile version 1.4.14.2616 against my kernel (some compile fixes were needed) and this Version works.
What changes are required to move to the newer Version? Was there something changed like clock activation?
I also noticed that the crash happens while waiting on a register change, i did put a trace there to look at the address of the register in question and the exact same address seems to be successfully fetched during the run of the init script (rc.pvr).
Maybe it has something to do with power-management (PVRSRVSetDevicePowerStateKM is in the stack trace)?
Thanks a lot for the logs/details provided. Appreciate it.
Did you see the problem with 2.6.37 kernel as well?
The graphics sdk release notes would provide details on toolchain/kernel versions validated with for all supported platforms -
http://processors.wiki.ti.com/index.php/RN_4_05_00_03
In order to isolate the problem, can you try the manual steps below-
(rmmod first in case already inserted by default & then do below steps)
devmem2 0x48004B48 w 0x2devmem2 0x48004B10 w 0x1devmem2 0x48004B00 w 0x2
insmod pvrsrvkm.ko
insmod omaplfb.ko
Run /usr/bin/ES3.0/pvrsrvinit
If you do not see any problems with above steps, try running any 3D demo under -
/usr/bin/SGX/demos/Raw/OGLES2.
Also you had mentioned it works fine with 1.4.14.2616. Did you try other 1.6 versions before trying this & still saw the issue with any 1.6 version ?
Thanks,
Prathap.

Hi,first of all thanks for your interest in this issue!i disabled my init-script and tried the commands mentioned. The result was, that /usr/bin/ES3.0/pvrsrvinit died with the same stack trace as the test application before.Most interesting is that the init-script does something very similar and seems to succeed.it comes essentially down to:insmod /lib/modules/3.2.1/kernel/drivers/gpu/pvr/pvrsrvkm.komodprobe omaplfbmodprobe bufferclass_tidevmem2 0x48004B48 w 0x2devmem2 0x48004B10 w 0x1devmem2 0x48004B00 w 0x2/usr/bin/pvrsrvinitthis runs without error until a test application is started (i only have pvr2d_test on my device at the moment)while if i turn it around:devmem2 0x48004B48 w 0x2devmem2 0x48004B10 w 0x1devmem2 0x48004B00 w 0x2insmod /lib/modules/3.2.1/kernel/drivers/gpu/pvr/pvrsrvkm.komodprobe omaplfbmodprobe bufferclass_ti/usr/bin/pvrsrvinitit crashes with the same stacktrace as the test application would.I've yet to try other 1.6 versions.
Thanks a lot for the clear explanation/steps.
Now you have mentioned that -
insmod /lib/modules/3.2.1/kernel/drivers/gpu/pvr/pvrsrvkm.komodprobe omaplfbmodprobe bufferclass_tidevmem2 0x48004B48 w 0x2devmem2 0x48004B10 w 0x1devmem2 0x48004B00 w 0x2/usr/bin/pvrsrvinitthis runs without error until a test application is started.
At this stage ,before starting application, can you read back the register values using devmem. See if its the same values as we wrote above.
If it has changed, run the 3 devmem commands again just before running the test app & see if app crashes now.
The description you provided is conveying that somehow SGX clocks are getting disabled. Did you see this with 2.6.37 kernel as well?
We ran the tests again on OMAP3530 EVM to confirm (with 2.6.37 kernel as mentioned in release notes) and it works fine. Logs below-
# cputypeOMAP3530# ./pvr2d_test //No error or crash seen# /opt/gfxsdkdemos/ogles2/OGLES2ChameleonMan //3D demos run finePVRShell: EGL 1.4 initialized# cat /proc/pvr/versionVersion 1.6.16.4117 (release) /home1/prathap/Graphics_SDK_4_05_00_03/GFX_Linux_KMSystem Version String: SGX revision = 1.2.1# uname -a2.6.37 #8 Tue Jan 31 11:38:57 IST 2012 armv7l unknown
Can you check the ouput of cputype command on your board? Also it would be helpful to see results on your system against 2.6.37 kernel.
This would help us isolate if its a setup/environment or a kernel specific issue.
Also share the download link to the 3.2 kernel sources you are using.
Also, you can try the build and install of standalone graphics SDK against the 3.2 kernel you have if possible. The latest release package 04.05.00.03 is available at -

Release notes-
Hello,
I also get kernel BUGs in omap_l3_smx.c, and this is with kernel 3.2.2. It happens when I run audio at lower latencies, which causes more interrupts to happen. Simultaneously as the CPU load gets higher (for instance, if I increase the amount of audio DSP), then I get these kernel BUGs more frequently. If you want some more of these kernel BUG traces, just let me know -- I have lots of them.
Best regards,
Edgar

Can you please raise this as a new query? This will help the audio driver expert to help you with this problem. The current thread discussion is about SGX(graphics).
Please close this query if the graphics(SGX) related issue is resolved.
Sorry I thought it was related -- the kernel is stopping at the same line in omap_l3_smx.c. It is unobvious to me that an application can crash the L3 bus, so I thought maybe the problem was with the bus driver omap_l3_smx.c. I will re-post the question as a new query.
Best,
