Best, Jack -----Original Message----- From: Jack Zhang <[email protected]> Sent: Monday, December 2, 2019 7:05 PM To: [email protected] Cc: Zhang, Jack (Jian) <[email protected]> Subject: [PATCH] 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.
