<pre>I tried to use intel_rug but it doesn't read registers for some reason.
intel-gpu-tools package from Ubuntu repository, version 1.2.2:
~$ sudo intel_reg read 0x180000:0x61250 0x180000:0x61254 0x180000:0x61350
0x180000:0x61354
Error: /usr/share/intel-gpu-tools/registers/gen7_other.txt:1: ('RCS_MODE_GEN7',
'0x0000229c', '')
Error: /usr/share/intel-gpu-tools/registers/cherryview:10: gen7_other.txt
Warning: reading '/usr/share/intel-gpu-tools/registers/cherryview' failed.
Using builtin register spec.
