From f56071d4403b1d1ac02e1d74e1683102f23ba031 Mon Sep 17 00:00:00 2001 From: Wenhui Sheng Date: Mon, 29 Jun 2020 13:38:58 +0800 Subject: [PATCH] drm/amdgpu: correct discovery_tmr_size init val The legacy way to initialize discovery_tmr_size is using DISCOVERY_TMR_SIZE, while after we reduce DISCOVERY_TMR_SIZE from 64KB to 4KB, variable discovery_tmr_size is also reduced to 4KB, this is not correct, it still should be 64KB, discovery_tmr_size will be used to calculate ip_discovery reserved mem's start address and size. Using DISCOVERY_TMR_OFFSET to init discovery_tmr_size instead.
