You're using the classic Intel driver (i965_dri.so) on Baytrail.

If you want to be able to use tools like sysprof or perf, you just need to 
build Mesa with debugging symbols.

I recommend:

CFLAGS='-g -O2 -fno-omit-frame-pointer' CXXFLAGS='-g -O2 -fno-omit-frame-
pointer' ./autogen.sh --enable-gles1 --enable-gles2 --enable-glx-tls --with-
egl-platforms=x11,drm --with-gallium-drivers= --with-dri-drivers=i965,swrast

This should give you actual function names instead of ?? inside of
