From f1cf138d867411f220d694a272b07352f68edb6f Mon Sep 17 00:00:00 2001 From: Jack Xiao Date: Tue, 28 May 2019 13:27:11 +0800 Subject: [PATCH 2645/2940] drm/amdgpu/gfx10: fix programming of SC_HIZ_TILE_FIFO_SIZE field max fifo size is 128 and PA_SC_FIFO_SIZE[20:15]=SC_HIZ_TILE_FIFO_SIZE field is programmed in units of two entries, but 6 bits is insufficient to hold value 128/2 = 64, so set this field as 0 which is interpreted by the hardware as maximum physical fifo size(128).
