Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-linux-mips@oss.sgi.com Precedence: bulk Return-Path: X-Orcpt: rfc822;linux-mips-outgoing I looked into the R5000 support and have a couple of questions: 1. Is R5000, specifically NEC Vr5000, fully supported? I have seen CONFIG_CPU_R5000 defined, but it does not appear to do much. 2. Specifically, NEC Vr5000 has two-way set-associative cache. I browsed through the cache code, and got concerned that I don't see any code that seems to take care of that. Do I miss something? 3. I understand Geert has a port to DDB5074 (with Vr5000 CPU). Is this port completed (including all interrupts, PCI related stuff). Is this port reliable? Thanks a lot. Jun
