Subject: drm/amdkfd: expose num_sdma_queues_per_engine data field to topology
Git-commit: bb71c74db3c554a10d8df81c2dcc162b0bbb4149
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
node (v2)
Thunk driver would like to know the num_sdma_queues_per_engine data, however
this data relied on different asic specific. So it's better to get it from kfd
driver.
v2: don't update the name size.
