pvrsrvkm_sgx540_120.ko fails to load on 4AJ.2.3

Other Parts Discussed in Thread: 4460, 4430

I am in the process of porting our code base from 4AJ.2.1 to 4AJ.2.3 and android will not start. I have determined this is because the sgx driver will not load so I get errors in the HWC.

shell@android:/ $ [ 6.349304] pvrsrvkm_sgx540_120: disagrees about version of symbol thermal_cooling_dev_register
[ 6.358978] pvrsrvkm_sgx540_120: Unknown symbol thermal_cooling_dev_register (err -22)
[ 6.368316] pvrsrvkm_sgx540_120: disagrees about version of symbol thermal_cooling_dev_unregister
[ 6.378051] pvrsrvkm_sgx540_120: Unknown symbol thermal_cooling_dev_unregister (err -22)

I built everything for 4AJ.2.1 and didn't have this problem so I know my build process is OK. Any ideas what is going on here?

thanks,

Are you using OMAP 4430, 4460, or 4470? There is a known issue with the 4AJ.2.3 release that affects OMAP 4430 and 4460, I believe. Thus, you should plan to use 4AJ.2.2 instead of 4AJ.2.3 for now. Please contact your TI representative for full details if needed.

We are using a 4460. We went to 2.3 so we could get Jelly Bean 4.2. Is the problem just with the sgx driver or something else?

thanks,

Make sure to rebuild the modules for your new kernel, as described here:

Gina,

Thanks, I'll take a look at that one also. While looking at all the patchset on the review site I saw this one: http://review.omapzoom.org/#/c/31834, "Rebuilt sgx binaries required because of a kernel change that requires sgx to be rebuilt" which sounds like it will fix my original problem. I'll pull in the changes and see how it looks.

thanks,

jeff
