From daae5be7cdfd04391cb447f0ec09f4ddc9feb1f9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4623/4736] amd/amdgpu/sriov swSMU disable for sriov
For boards greater than ARCTURUS, and under sriov platform,
swSMU is not supported because smu ip block is commented at
guest driver.
Generally for sriov, initialization of smu is moved to host driver.
Thus, smu sw_init and hw_init will not be executed at guest driver.
Without sw structure being initialized in guest driver, swSMU cannot
declare to be supported.
