All I/O subsystems +connect to this bus. +The devices can be either on seperate chips, expansion +cards or on an integrated megacell, like the LASI MBA. +.Pp +The +.Tn GSC +bus is a 32-bit wide, address and data multiplexed bus. In its "standard" +implementation it has a maximum throughput of 160MB/s, the "2x" implementation +reaches up to 250MB/s. +Some HPPA CPUs directly attach to this bus, namely the PA7100LC and PA7300LC. +.Pp +As for the expansion cards, there appeared different form-factors, depending on +bus-speed (standard or 2x) and specific models. +The standard formfactor is the "EISA form-factor", cards that look like +typical EISA cards with a different connector (100-pin female EBBL). +The Series 712 have their own special type +of GSC expansion cards, called the "GIO form-factor", which is quite small and +mostly has only one VLSI chip on it (in most cases LASI/WAX). +Newer systems sometimes feature the "HSC formfactor", that is a 1U-VME +card-like expansion card with a 100-pin male pin+socket connector. +Mixing cards with different speeds is supported but downgrades +the performance of the whole I/O-subsystem. +.Pp +.Sh SUPPORTED DEVICES +The system includes machine-dependent +.Tn GSC +drivers, sorted by driver name: +.Bl -tag -width pcdisplay -offset indent +.It Xr com 4 +RS-232 ports. +.It Xr hil 4 +Human Interface Loop, for HP-proprietary input devices like keyboard and mice. +.It Xr ie 4 +Intel i82C596 DX/CA 32-bit Ethernet interfaces. +.It Xr lpt 4 +Centronics printer port. +.It Xr pckbc 4 +PC-style keyboard controller. +.It Xr siop 4 +NCR 53C700/710 narrow, single-ended or 53C720 wide, +differential SCSI I/O processor. +.El +.Pp +Some of these +.Tn GSC +devices also have +.Tn PCI +, +.Tn EISA +or +.Tn ISA +equivalents. +These are listed in +.Xr pci 4 , +.Xr eisa 4 , +or +.Xr isa 4 , .Sh SEE ALSO .Xr asp 4 , +.Xr cpu 4 , .Xr intro 4 , .Xr lasi 4 .Sh HISTORY diff --git a/share/man/man4/man4.hppa/lasi.4 b/share/man/man4/man4.hppa/lasi.4 index 0dd95ddf142..4e4c7da0dce 100644 --- a/share/man/man4/man4.hppa/lasi.4 +++ b/share/man/man4/man4.hppa/lasi.4 @@ -1,4 +1,4 @@ -.\" $OpenBSD: lasi.4,v 1.7 2002/04/03 22:44:25 mickey Exp $ +.\" $OpenBSD: lasi.4,v 1.8 2002/04/07 10:14:31 mickey Exp $ .\" .\" .\" Copyright (c) 1999 Michael Shalayeff @@ -39,7 +39,7 @@ workstations and single-board computers. .Sh SYNOPSIS .Cd "lasi0 at mainbus? irq 28" -.Cd "gscbus* at lasi?" +.Cd "gsc* at lasi?" .Sh INTRODUCTION The supported Core bus controllers are those used in conjuction with .Tn PA7100LC |
