intel_reg_dumper(1) Decode a bunch of Intel GPU registers for debugging


intel_reg_dumper [ file ]


intel_reg_dumper is a tool to read and decode the values of many Intel GPU registers. It is commonly used in debugging video mode setting issues. If the file argument is present, the registers will be decoded from the given file instead of the current registers. Use the intel_reg_snapshot tool to generate such files.



If set, decode as though the GPU has a PCH split. This is only necessary for Intel HD (Ironlake) and later register dumps in files; live decodes get this correct automatically.
