From 81df08ddefd7cbb336efedbca2eb8a7429b8f748 Mon Sep 17 00:00:00 2001 From: mjacob Date: Tue, 9 Jan 2001 18:54:06 +0000 Subject: [PATCH] Use a SNS REGISTER FC4 TYPE subcommand to register with the name server. This means we should be able to work with McData switches now. Change ISPASYNC_PDB_CHANGED to ISPASYNC_LOGGED_INOUT (more descriptive). Allow F-Port topologies to use target ids 0..125 to log into fabric devices. Yet again fool around with defaul WWN stuff. --- sys/dev/ic/isp.c | 147 ++++++++++++++++++++++++++++++++++------------- 1 file changed, 108 insertions(+), 39 deletions(-) diff --git a/sys/dev/ic/isp.c b/sys/dev/ic/isp.c index e0d3c5328815..7c6c0d4ce4b2 100644 --- a/sys/dev/ic/isp.c +++ b/sys/dev/ic/isp.c @@ -1,4 +1,4 @@ -/* $NetBSD: isp.c,v 1.68 2000/12/30 19:47:20 mjacob Exp $ */ +/* $NetBSD: isp.c,v 1.69 2001/01/09 18:54:06 mjacob Exp $ */ /* * This driver, which is contained in NetBSD in the files: * @@ -150,6 +150,7 @@ static int isp_same_lportdb __P((struct lportdb *, struct lportdb *)); static int isp_pdb_sync __P((struct ispsoftc *, int)); #ifdef ISP2100_FABRIC static int isp_scan_fabric __P((struct ispsoftc *)); +static void isp_register_fc4_type __P((struct ispsoftc *)); #endif static void isp_fw_state __P((struct ispsoftc *)); static void isp_mboxcmd __P((struct ispsoftc *, mbreg_t *, int)); @@ -177,7 +178,7 @@ isp_reset(isp) { mbreg_t mbs; int loops, i, touched, dodnld = 1; - char *revname; + char *revname = "????"; isp->isp_state = ISP_NILSTATE; @@ -1413,19 +1414,12 @@ isp_fclink_test(isp, usdelay) lp->portid = BITS2WORD(pdb.pdb_portid_bits); lp->loopid = pdb.pdb_loopid; lp->loggedin = lp->valid = 1; -#if 0 - if (isp->isp_rfabric == 0) { - isp_i_register_fc4_type(isp); - } -#endif + isp_register_fc4_type(isp); } else #endif { fcp->isp_portid = mbs.param[2]; fcp->isp_onfabric = 0; -#if 0 - isp->isp_rfabric = 0; -#endif fcp->portdb[FL_PORT_ID].valid = 0; } @@ -1482,7 +1476,7 @@ isp_pdb_sync(isp, target) struct lportdb *lp, *tport; fcparam *fcp = isp->isp_param; isp_pdb_t pdb; - int loopid, prange, lim; + int loopid, frange, prange, lim; #ifdef ISP2100_FABRIC /* @@ -1500,12 +1494,14 @@ isp_pdb_sync(isp, target) switch (fcp->isp_topo) { case TOPO_F_PORT: case TOPO_PTP_STUB: - prange = 0; + frange = prange = 0; break; case TOPO_N_PORT: + frange = FC_SNS_ID+1; prange = 2; break; default: + frange = FC_SNS_ID+1; prange = FL_PORT_ID; break; } @@ -1740,7 +1736,7 @@ isp_pdb_sync(isp, target) /* * Tell the outside world we've arrived. */ - (void) isp_async(isp, ISPASYNC_PDB_CHANGED, &i); + (void) isp_async(isp, ISPASYNC_LOGGED_INOUT, &i); } /* @@ -1755,7 +1751,7 @@ isp_pdb_sync(isp, target) * Tell the outside world we've gone away. */ loopid = lp - fcp->portdb; - (void) isp_async(isp, ISPASYNC_PDB_CHANGED, &loopid); + (void) isp_async(isp, ISPASYNC_LOGGED_INOUT, &loopid); MEMZERO((void *) lp, sizeof (*lp)); } @@ -1763,27 +1759,39 @@ isp_pdb_sync(isp, target) /* * Now log in any fabric devices */ - for (lp = &fcp->portdb[FC_SNS_ID+1]; + for (lp = &fcp->portdb[frange]; lp < &fcp->portdb[MAX_FC_TARG]; lp++) { u_int32_t portid; mbreg_t mbs; + loopid = lp - fcp->portdb; + if (loopid >= FL_PORT_ID && loopid <= FC_SNS_ID) { + continue; + } + /* * Anything here? */ - if (lp->port_wwn == 0) + if (lp->port_wwn == 0) { continue; + } /* * Don't try to log into yourself. */ - if ((portid = lp->portid) == fcp->isp_portid) + if ((portid = lp->portid) == fcp->isp_portid) { continue; + } /* * If we'd been logged in- see if we still are and we haven't * changed.
