From 065e4bdfa1f3ab2884c110394d8b7e7ebe3b988c Mon Sep 17 00:00:00 2001 From: Oak Zeng Date: Fri, 8 Feb 2019 15:44:35 -0600 Subject: [PATCH] drm/amdkfd: Fix sdma queue map issue Previous codes assumes there are two sdma engines. This is not true e.g., Raven only has 1 SDMA engine. Fix the issue by using sdma engine number info in device_info.
