i think we can use a function to retrieve this information without storing it separately.<br>

likes: <i><span> ret = smu_get_atom_data_table(smu, index, &size, &frev, &crev, <br>

<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
<span>because these information is a generic information from atom_common_table_header.</span></div>

<span>and other function don't care it except in smu_v11_0_get_clk_info_from_vbios.</span></div>
