drm/amdgpu: move buffer funcs setting up a level

2023-10-26T20:04:24+00:00

Rather than doing this in the IP code for the SDMA paging engine, move it up to the core device level init level. This should fix the scheduler init ordering. v2: drop extra parens v3: drop SDMA helpers v4: Added a Fixes tag because amdgpu dereferences an uninitialized scheduler without this patch, and this patch fixes this.

[why] User mode driver need to check the sdma ucode version to see whether the sdma engine supports a new type of PM4 packet. In SRIOV, sdma is loaded by the host. And, there is no way to check the sdma ucode version of CHIP_NAVI12 and CHIP_SIENNA_CICHLID of the host in the guest machine.
