[igt-dev] [PATCH i-g-t 1/4] lib/intel_reg: Add common MI_* macros to remove duplicates

Zbigniew Kempczyński zbigniew.kempczynski at intel.com
Tue Jun 7 05:24:08 UTC 2022


In few tests we got some MI_* duplicates (MI_MATH for example).
Add common definitions in intel_reg.h and remove local definitions
in the tests.
