2020-03-10T19:55:11+00:00

and remove each ras IP's own debugfs creation

this is required to fix ras when the driver does not use the drm load
and unload callbacks due to ordering issues with the drm device node.

drm/amdgpu: move xgmi init/fini to xgmi_add/remove_device call (v2)

2020-02-06T20:04:36+00:00

For sriov, psp ip block has to be initialized before
ih block for the dynamic register programming interface
that needed for vf ih ring buffer. On the other hand,
current psp ip block hw_init function will initialize
xgmi session which actaully depends on interrupt to
return session context. This results an empty xgmi ta
session id and later failures on all the xgmi ta cmd
invoked from vf. xgmi ta session initialization has to
be done after ih ip block hw_init call.

to unify xgmi session init/fini for both bare-metal
sriov virtualization use scenario, move xgmi ta init
to xgmi_add_device call, and accordingly terminate xgmi
ta session in xgmi_remove_device call.

The existing suspend/resume sequence will not be changed.

drm/amdgpu: Create generic DF struct in adev

2020-01-14T15:18:41+00:00

The only data fabric information the adev struct currently
contains is a function pointer table. In the near future,
we will be adding some cached DF information into adev. As
such, this patch creates a new amdgpu_df struct for adev.
Right now, it only containst the old function pointer table,
but new stuff will be added soon.
