Subject: [PATCH] drm/amdgpu: fix the incorrect external id for raven series
Date: Wed, 30 Jan 2019 19:57:51 +0800 [thread overview]
Message-ID: <1548849471-27890-1-git-send-email-ray.huang@amd.com> (raw)
This patch fixes the incorrect external id that kernel reports to user mode
driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should
start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while
rev_id == 1.
