3500602a29e33748452f Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 19 Aug 2016 18:18:26 +0100 Subject: MIPS: Stop setting I6400 FTLBP The FTLBP field in Config7 for the I6400 is intended as chicken bits for debugging rather than as a field that software actually makes use of. For best performance, FTLBP should be left at its default value of 0 with all TLB writes hitting the FTLB by default. Additionally, since set_ftlb_enable is called from decode_configs before decode_config4 which determines the size of the TLBs, this was previously always setting FTLBP=3 for a 3:1 FTLB:VTLB write ratio which makes abysmal use of the available FTLB resources. This effectively reverts b0c4e1b79d8a ("MIPS: Set up FTLB probability for I6400").
