From 4c2b2453ef9be2e105a987cd13cf3ce14e53f5e0 Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Tue, 27 Sep 2016 16:39:58 +0800 Subject: [PATCH] drm/amdgpu:properly fix some JumpTable issues we found some MEC ucode leads to IB test fail or even ring test fail if Jump Table of it is not start in FW bo with page aligned address, fixed by always make JT address page aligned. we don't need to patch JT2 for MEC2, because for VI, MEC2 is a copy of MEC1, thus when converting fw_type for MEC_JT2 we just return MEC1,hw can use the same JT for both MEC1 & MEC2. above two change fixed some ring/ib test failure issue for some version of MEC ucode.
