drm/amdgpu/psp: dont warn on missing optional TA's

2020-04-07T18:07:41Z

Replace dev_warn() with dev_info() and note that they are optional to avoid confusing users. The RAS TAs only exist on server boards and the HDCP and DTM TAs only exist on client boards. They are optional either way. Acked-by: Nirmoy Das Signed-off-by: Alex Deucher

drm/amdgpu: Fix GPU reset error.

2020-03-06T19:32:24Z

Problem: During GU reset PSP's sysfs was being wrongly reinitilized during call to amdgpu_device_ip_late_init which was failing with duplicate error. Fix: Move psp_sysfs_init to psp_sw_init to avoid this. Add guards in sysfs file's read and write hook agains premature call if PSP is not finished initialization.

drm/amdgpu: cleanup some incorrect reg access for SRIOV

2020-02-25T16:01:25Z

1) we shouldn't load PSP kdb and sys/sos for VF, they are supposed to be handled by hypervisor 2) ih reroute doesn't work on VF thus we should avoid calling it, besides VF should not use those PSP register sets for PF 3) shouldn't load SMU ucode under SRIOV, otherwise PSP would report error Signed-off-by: Monk Liu Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher
