drm/amdgpu: adjust sequence of ip_discovery init and timeout_setting

2020-04-01T18:44:43Z

what: 1)move timtout setting before ip_early_init to reduce exclusive mode cost for SRIOV 2)move ip_discovery_init() to inside of amdgpu_discovery_reg_base_init() it is a prepare for the later upcoming patches. why: in later upcoming patches we would use a new mailbox event -- "req_gpu_init_data", which is a callback hooked in adev->virt.ops and this callback send a new event "REQ_GPU_INIT_DAT" to host to notify host to do some preparation like "IP discovery/vbios on the VF FB" and this callback must be: A) invoked after set_ip_block() because virt.ops is configured during set_ip_block() B) invoked before ip_discovery_init() becausen ip_discovery_init() need host side prepares everything in VF FB first. current place of ip_discovery_init() is before we can invoke callback of adev->virt.ops, thus we must move ip_discovery_init() to a place after the adev->virt.ops all settle done, and the perfect place is in amdgpu_discovery_reg_base_init() Signed-off-by: Monk Liu Reviewed-by: Emily Deng Signed-off-by: Alex Deucher
