Trouble with Native OpenGL Renderer

Question

I am using Native code to render OpenGL in Android and I get periodic errors that look like this:

ERROR/IMGSRV(1435): frameresource.c:610: WaitUntilResourceIsNotNeeded: PVRSRVEventObjectWait failed

ERROR/IMGSRV(1018): sgxif.c:124: WaitForRender: PVRSRVEventObjectWait failed

ERROR/IMGSRV(1435): osfunc_um.c:318: PVRSRVEventObjectWait: Error 13 returned

Once these errors come up I have to restart the phone or the rendering won't start again correctly. I have done a lot of web searching and I can't find out what could be the cause of these errors. Does anyone else have any suggestions?

Answer 1

Not an answer, but some potentially useful info:

I found the symbol PVRSRVEventObjectWait in an OMAP sgx driver patch. It appears that something you're doing is pissing off the OMAP graphics drivers.

Given the text of the message, I'm going to hazard a guess and say that either a resource is being leaked, or the graphics calls are being used improperly from multiple threads.

I wouldn't expect to get a much better answer than that on this site without some test source code.
