Subject[PATCH 49/83] hsa/radeon: Add kernel queue support for KFD
Date
From: Ben Goz <ben.goz@amd.com>

The kernel queue module enables the KFD to establish kernel queues, not exposed
to user space. The kernel queues are used for HIQ (HSA Interface Queue) and DIQ
(Debug Interface Queue) operations.
