Thanks!

0x51 was only made available for GC 11.0.4 AFAICT.

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.

commit f81cd793119e7 ("drm/amd/amdgpu: Fix MES init sequence") caused
a dependency on new enough MES firmware to use amdgpu.  This was fixed
on most gfx11 and gfx12 hardware with commit 0180e0a5dd5c6
("drm/amdgpu/mes: add compatibility checks for set_hw_resource_1"),
but this left out that GC 11.0.4 had breakage at MES 0x51.

Bump the requirement to 0x52 instead.

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