I am porting rowboat Gingerbread system to our custom OMAP DM3730 target based on beagleboard. Graphics are running with our Gingerbread system built from sources (DevKit 1.0 from TI_Android_GingerBread_2_3_Sources.tar.gz), but appear to be running oddly When running with omapfb.debug=y, the kernel messages report 2 overlay updates for frame buffer0 when it should be doing a single update only. I don't see anything else in the kernel causing this, so I believe the Surfaceflinger an PVR server or EGL libraries are driving this. I am looking for more debugging information to verify what is causing this behavior.
I am currently trying to get more information on how the PVR server and libraries are running with the kernel using the debug version of the SGX drivers with the rowboat Gingerbread built from sources. Even though the kernel version 1.7.17.4352 seems to match the strings libIMGegl.so 1.7.17.4352, I am getting a PVR KM mismatch:
PVR_K: (FAIL) SGXInit: Mismatch in client-side and KM driver build options; extr
a options present in KM: (0x1). Please check sgx_options.h
But the flag it is complaining about is the debug flag?
Question: Does anyone know how to build the debug version of the SGX kernel drivers from DevKit 1.0 sources? Do I need to advance to DevKit 2.0 for this?
I ran the gfx_check.sh as follows. Note: eglinfo.apk won't run on debug system because Android can't start with above error. On running system with "release" drivers, eglinfo is a blank screen?
Here is my startup messages and gfx_check results
