From 6c509124e7d3d2e8433c61a1a5057ada5a9f37da Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexander.deucher@amd.com>
Date: Wed, 8 May 2019 22:47:56 -0500
Subject: [PATCH 2809/2940] drm/amdkfd: Introduce XGMI SDMA queue type for
gfx10
Existing QUEUE_TYPE_SDMA means PCIe optimized SDMA queues.
Introduce a new QUEUE_TYPE_SDMA_XGMI, which is optimized
for non-PCIe transfer such as XGMI.
Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
