drm/amdgpu: get extended xgmi topology data

2021-08-18T22:22:24+00:00

The TA has a limit to the amount of data that can be retrieved from
GET_TOPOLOGY.  For setups that exceed this limit, the xGMI topology
needs to be re-initialized and data needs to be re-fetched from the
extended link records by setting a flag in the shared command buffer.

The number of hops and the number of links must be accumulated by the
driver. Other data points are all fetched from the first request.
Because the TA has already exceeded its link record limit, it
cannot hold bidirectional information.  Otherwise the driver would
have to do more than two fetches so the driver has to reflect the
topology information in the opposite direction.

Report the min/max bandwidth in megabytes to the kfd for direct
xgmi connections only.  Indirect peers will report 0 since

drm/amdgpu: move xgmi ras functions to xgmi_ras_funcs

2021-04-09T20:51:07+00:00

xgmi ras is not managed by gpu driver when gpu is
connected to cpu through xgmi. move all xgmi ras
functions to xgmi_ras_funcs so gpu driver only
initializes xgmi ras functions when it manages
xgmi ras.

drm/amdgpu: Reset the devices in the XGMI hive duirng probe

2021-03-24T03:10:38+00:00

In passthrough configuration, hypervisior will trigger the SBR(Secondary bus reset) to the devices
without sync to each other. This could cause device hang since for XGMI configuration, all the devices
within the hive need to be reset at a limit time slot. This serial of patches try to solve this issue
by co-operate with new SMU which will only do minimum house keeping to response the SBR request but don't
do the real reset job and leave it to driver. Driver need to do the whole sw init and minimum HW init
to bring up the SMU and trigger the reset(possibly BACO) on all the ASICs at the same time

drm/amdgpu: mask the xgmi number of hops reported from psp to kfd

2021-03-24T02:58:03+00:00

The psp supplies the link type in the upper 2 bits of the psp xgmi node
information num_hops field.  With a new link type, Aldebaran has these
bits set to a non-zero value (1 = xGMI3) so the KFD topology will report
the incorrect IO link weights without proper masking.
The actual number of hops is located in the 3 least significant bits of
this field so mask if off accordingly before passing it to the KFD.
