Thanks. Will modify to remove the check since all SDMA 4_x share the same setting logic.

Thanks,
Feifei

[AMD Public Use]

There shouldn't be any check based on ASIC type. If a check is required, it should be based on  AMD_CG_SUPPORT_SDMA_MGCG and AMD_CG_SUPPORT_SDMA_LS. We set the flags appropriately for each ASIC in soc15.

Thanks,
Lijo

VegaM is SDMA 3.x.
