From 082a1cee4f26da42fda20211729a56c2bebafce9 Mon Sep 17 00:00:00 2001
From: Felix Kuehling <Felix.Kuehling@amd.com>

Subject: [PATCH 3392/4131] drm/amd: Update kgd_kfd interface for resuming SDMA
queues
Add wptr and mm parameters to hqd_sdma_load and pass these parameters
from device_queue_manager through the mqd_manager.
SDMA doesn't support polling while the engine believes it's idle. The
driver must update the wptr. The new parameters will be used for looking
up the updated value from the specified mm when SDMA queues are resumed
after being disabled.
