[PATCH] drm/amdgpu: Use function pointer for some mmhub functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add more function pointers to amdgpu_mmhub_funcs. ASIC specific
implementation of most mmhub functions are called from a general
function pointer, instead of calling different function for
different ASIC. Simplify the code by deleting duplicate functions
