Hi Christian,
I used smu7_hwmgr for all the asics of smu version 7 , CI and Vi. Please see
powerplay code refactoring patches.
But some functions in the table were different between those asics. so we
needed to overload those functions for some asics.
for example:
from tonga. we used pptable version 1, but ci and iceland, no pptable,
so needed to overload related functions:
hwmgr->hwmgr_func = &smu7_hwmgr_funcs;
hwmgr->pptable_func = &pptable_v1_0_funcs;
pp_smu7_thermal_initialize(hwmgr);
+ if (hwmgr->pp_table_version == PP_TABLE_V0) {
+ hwmgr->hwmgr_func->get_pp_table_entry =
&smu7_get_pp_table_entry_v0;
+ hwmgr->hwmgr_func->get_num_of_pp_table_entries =
smu7_get_number_of_powerplay_table_entries_v0;
+ hwmgr->pptable_func = &pptable_funcs;
+ }
Best Regards
Rex

Subject: Re: [PATCH 0/9] misc patches related to powerplay
Patch #1-#7 and #9 are Acked-by: Christian König <[email protected]>.
Patch #8: That looks fishy, usually we don't want to override static
functions tables.
So what is the specific use case here?
Regards,
Christian.
