From 3a0102536bdbf00629e6ba944bd55ee0ec77fb52 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Mon, 20 Feb 2006 23:41:50 -0500 Subject: Get rid of the code that delays PIO write accesses until the cache access occurs. The fundamental problem is that a subsequent read that occurs functionally will get a functionally incorrect result that can break driver code. dev/ns_gige.cc: dev/ns_gige.hh: dev/sinic.cc: dev/sinic.hh: get rid of pio_delay write and the associated code to move the write to the cache access function dev/sinicreg.hh: no more write delays python/m5/objects/Ethernet.py: get rid of pio_delay write --HG-- extra : convert_revision : 1dcb51b8f4514e717bc334a782dfdf06d29ae69d --- python/m5/objects/Ethernet.py | 1 -
