[AMD Official Use Only - AMD Internal Distribution Only] Yes , I can confirm that from 0x52 , the mes have the set_hw_resource_1 API support on gfx_11. Actually , I don't see a official release on 0x51 from mes side , maybe it's an internal testing version.

Do we know that 0x52 actually has it? @Shaoyun Liu can you verify?
