PB Limit reached Warning


#1
Hello,

 

I am currently using OpenGL ES 2.0 thanks to PVR Insider SDK on TI Blaze Platform (OMAP 4430, GPU: SGX540, OS: Ubuntu).

 

When I am using a high resolution texture (2000*1500), the warning message below is printed for each frame:

 

PVR:(Warning): GrowPerContextPB: PB Limit reached [1000,  /sgxpb.c]

 

 

I suspect it's because my texture is not far from the maximal resolution supported by the Blaze.

Yet I'd like to know how I could get rid of this message since it's very painful to see it printed for each frame.

 

Thanks for your answer

Hi Adrian,

Can you cat /proc/pvr/version on your Blaze and share the version number, please?
It sounds like you might be on an out of date driver. You should contact TI to see if they have an update they can give you.

Joe

Hi Joe,

 

My version is the 1.7.17.4403 and the SGX revision is 1.2.0.

 

Thanks for your reply.

Hi Adrian,

That’s a fairly old 1.7 driver. If you contact TI, they should be able to give an updated version.

Hi Joe,


Thanks for your reply.

 

The driver is indeed an old one.

I am going to update it.

 

Thanks

Hi Joe,

 

Just to confirm you that after updating the driver, the warnings disappeared.

 

Once again thanks for your help and your replies.
