From a63222db3a2dfe97537f8ae60eaed26d3b928e55 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Wed, 26 Apr 2017 18:23:09 +0000 Subject: [PATCH] Remove the cy(4) driver for Cyclades serial adapters. This driver has been disconnected from the build since the new tty layer was introduced in 8.0 and was never updated for new tty. --- ObsoleteFiles.inc | 2 + share/man/man4/Makefile | 1 - share/man/man4/cy.4 | 257 ----- sys/conf/files | 3 - sys/dev/cy/cy.c | 2242 --------------------------------------- sys/dev/cy/cy_isa.c | 150 --- sys/dev/cy/cy_pci.c | 192 ---- sys/dev/cy/cyreg.h | 75 -- sys/dev/cy/cyvar.h | 36 - 9 files changed, 2 insertions(+), 2956 deletions(-) delete mode 100644 share/man/man4/cy.4 delete mode 100644 sys/dev/cy/cy.c delete mode 100644 sys/dev/cy/cy_isa.c delete mode 100644 sys/dev/cy/cy_pci.c delete mode 100644 sys/dev/cy/cyreg.h delete mode 100644 sys/dev/cy/cyvar.h diff --git a/ObsoleteFiles.inc b/ObsoleteFiles.inc index 2e6dff8a050..e9b2de5da32 100644 --- a/ObsoleteFiles.inc +++ b/ObsoleteFiles.inc @@ -38,6 +38,8 @@ # xargs -n1 | sort | uniq -d; # done +# 20170426: Remove cy(4) +OLD_FILES+=usr/share/man/man4/cy.4.gz # 20170425: NATM configuration support removed OLD_FILES+=etc/rc.d/atm1 OLD_FILES+=etc/rc.d/atm2 diff --git a/share/man/man4/Makefile b/share/man/man4/Makefile index b58d128a956..748bde20236 100644 --- a/share/man/man4/Makefile +++ b/share/man/man4/Makefile @@ -118,7 +118,6 @@ MAN= aac.4 \ cxgb.4 \ cxgbe.4 \ cxgbev.4 \ - cy.4 \ cyapa.4 \ da.4 \ dc.4 \ diff --git a/share/man/man4/cy.4 b/share/man/man4/cy.4 deleted file mode 100644 index c0c807286f1..00000000000 --- a/share/man/man4/cy.4 +++ /dev/null @@ -1,257 +0,0 @@ -.\" Copyright (c) 1990, 1991 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" This code is derived from software contributed to Berkeley by -.\" the Systems Programming Group of the University of Utah Computer -.\" Science Department. -.\" Redistribution and use in source and binary forms, with or without -.\" modification, are permitted provided that the following conditions -.\" are met: -.\" 1.

The only change was s/sio/cy/g. -.Pp -Serial ports controlled by the -.Nm -driver can be used for both `callin' and `callout'. -For each port there is a callin device and a callout device. -The minor number of the callout device is 128 higher -than that of the corresponding callin port. -The callin device is general purpose. -Processes opening it normally wait for carrier -and for the callout device to become inactive. -The callout device is used to steal the port from -processes waiting for carrier on the callin device. -Processes opening it do not wait for carrier -and put any processes waiting for carrier on the callin device into -a deeper sleep so that they do not conflict with the callout session. -The callout device is abused for handling programs that are supposed -to work on general ports and need to open the port without waiting -but are too stupid to do so. -.Pp -The -.Nm -driver also supports an initial-state and a lock-state control -device for each of the callin and the callout "data" devices. -The minor number of the initial-state device is 32 higher -than that of the corresponding data device. -The minor number of the lock-state device is 64 higher -than that of the corresponding data device. -The termios settings of a data device are copied -from those of the corresponding initial-state device -on first opens and are not inherited from previous opens. -Use -.Xr stty 1 -in the normal way on the initial-state devices to program -initial termios states suitable for your setup. -.Pp -The lock termios state acts as flags to disable changing -the termios state. -E.g., to lock a flag variable such as -CRTSCTS, use -.Em "stty crtscts" -on the lock-state device. -Speeds and special characters -may be locked by setting the corresponding value in the lock-state -device to any nonzero value. -.Pp -Correct programs talking to correctly wired external devices -work with almost arbitrary initial states and almost no locking, -but other setups may benefit from changing some of the default -initial state and locking the state. -In particular, the initial states for non (POSIX) standard flags -should be set to suit the devices attached and may need to be -locked to prevent buggy programs from changing them. -E.g., CRTSCTS should be locked on for devices that support -RTS/CTS handshaking at all times and off for devices that do not -support it at all. -CLOCAL should be locked on for devices -that do not support carrier. -HUPCL may be locked off if you do not -want to hang up for some reason. -In general, very bad things happen -if something is locked to the wrong state, and things should not -be locked for devices that support more than one setting. -The -CLOCAL flag on callin ports should be locked off for logins -to avoid certain security holes, but this needs to be done by -getty if the callin port is used for anything else. -.Ss Kernel Configuration Options -The -.Em CY_PCI_FASTINTR -option should be used to avoid suboptimal interrupt handling for -PCI Cyclades boards. -The PCI BIOS must be configured with the -.Nm -interrupt not shared with any other active device -for this option to work. -This option is not the default because it is currently harmful in -certain cases where it does not work. -.Sh FILES -.\" XXX more cloning: s/d/c/g and add a ? for the card number. -.Bl -tag -width /dev/ttyic?? -compact -.It Pa /dev/ttyc?? -for callin ports -.It Pa /dev/ttyic?? -.It Pa /dev/ttylc?? -corresponding callin initial-state and lock-state devices -.Pp -.\" XXX more cloning: s/a/c/g.
