freebsd kernel with SKQ

not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time. |

This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
