NO.

$ git clone git://anongit.freedesktop.org/xorg/app/intel-gpu-tools
intel-gpu-tools-git

$ cd intel-gpu-tools-git/

$ ./autogen.sh --disable-dumper <--- requires swig2.0 and python >=3.x

$ sudo ./tools/intel_reg_read 0x44008
0x44008 : 0x0

$ sudo ./tools/intel_reg_read 0xC4008
0xC4008 : 0x0

$ sudo ./tools/intel_reg_dumper > /tmp/intel_reg_dumper.txt <--- see attachment

Does this help you?
