[PATCH 8/9] drm/amdkfd: Change MQD manager to be H/W specific
Oded Gabbay
oded.gabbay at amd.com
Thu Jan 8 08:15:35 PST 2015
From: Ben Goz <ben.goz at amd.com>
The MQDs for CI and VI are different. Therefore, the MQD manager module need to
be H/W specific.
This patch splits the current MQD manager into three files:
- kfd_mqd_manager.c, which contains common functions and initializes the
specific mqd manager module according to the H/W
- kfd_mqd_manager_cik.c, which contains Kaveri specific functions. This is
basically the old kfd_mqd_manager.c
- kfd_mqd_manager_vi.c, which will contain VI specific functions. Currently it
is not implemented except for returning NULL on initialization.
