From 1ca224f36a896a2ae19c584ab2ee769125a0e66f Mon Sep 17 00:00:00 2001

Subject: [PATCH 3904/4256] drm/amdkfd: Remove unnecessary pm_init() for non
HWS mode
The packet manager is not needed for non HWS mode except Hawaii, so only
initialize it for Hawaii under non HWS mode. This will simplify debugging
under non HWS mode for all new asics, because it eliminates one variable
out of the equation in non HWS mode
