The test and libwrap code link using normal gcc (on gnu/linux type environment, I'm using armv7 ubuntu 11.10, but debian, etc, should work just fine), against an android libc and libC2D2, etc. The /system directory from an android snapdragon filesystem should be extracted under /system. You can find what you need from, for ex, a cyanogenmod filesystem for a snapdragon phone. You can run the test apps with wrapper lib like: LD_PRELOAD=`pwd`/libwrap.so ./test-copy > test-copy.log (run that as root or fix up permissions on /dev/kgsl-*) The redump utility can post process a set of .rd log files to generate a html table showing side-by-side comparisions of the cmdstream with params and gpuaddr's highlighted: ./redump copy*.rd > copy.html
