From 606d099cdd1080bbb50ea50dc52d98252f8f10a1 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 8 Dec 2006 02:38:45 -0800 Subject: [PATCH] tty: switch to ktermios This is the grungy swap all the occurrences in the right places patch that goes with the updates. At this point we have the same functionality as before (except that sgttyb() returns speeds not zero) and are ready to begin turning new stuff on providing nobody reports lots of bugs If you are a tty driver author converting an out of tree driver the only impact should be termios->ktermios name changes for the speed/property setting functions from your upper layers. If you are implementing your own TCGETS function before then your driver was broken already and its about to get a whole lot more painful for you so please fix it 8) Also fill in c_ispeed/ospeed on init for most devices, although the current code will do this for you anyway but I'd like eventually to lose that extra paranoia [akpm@osdl.org: bluetooth fix] [mp3@de.ibm.com: sclp fix] [mp3@de.ibm.com: warning fix for tty3270] [hugh@veritas.com: fix tty_ioctl powerpc build] [jdike@addtoit.com: uml: fix ->set_termios declaration] Signed-off-by: Alan Cox Signed-off-by: Martin Peschke Acked-by: Peter Oberparleiter Cc: Cornelia Huck Signed-off-by: Hugh Dickins Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/pty.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'drivers/char/pty.c') diff --git a/drivers/char/pty.c b/drivers/char/pty.c index 80d3eedd7f9..c07a1b5cd05 100644 --- a/drivers/char/pty.c +++ b/drivers/char/pty.c @@ -218,7 +218,7 @@ out: return retval; } -static void pty_set_termios(struct tty_struct *tty, struct termios *old_termios) +static void pty_set_termios(struct tty_struct *tty, struct ktermios *old_termios) { tty->termios->c_cflag &= ~(CSIZE | PARENB); tty->termios->c_cflag |= (CS8 | CREAD); @@ -272,6 +272,8 @@ static void __init legacy_pty_init(void) pty_driver->init_termios.c_oflag = 0; pty_driver->init_termios.c_cflag = B38400 | CS8 | CREAD; pty_driver->init_termios.c_lflag = 0; + pty_driver->init_termios.c_ispeed = 38400; + pty_driver->init_termios.c_ospeed = 38400; pty_driver->flags = TTY_DRIVER_RESET_TERMIOS | TTY_DRIVER_REAL_RAW; pty_driver->other = pty_slave_driver; tty_set_operations(pty_driver, &pty_ops); @@ -286,6 +288,8 @@ static void __init legacy_pty_init(void) pty_slave_driver->subtype = PTY_TYPE_SLAVE; pty_slave_driver->init_termios = tty_std_termios; pty_slave_driver->init_termios.c_cflag = B38400 | CS8 | CREAD; + pty_slave_driver->init_termios.c_ispeed = 38400; + pty_slave_driver->init_termios.c_ospeed = 38400; pty_slave_driver->flags = TTY_DRIVER_RESET_TERMIOS | TTY_DRIVER_REAL_RAW; pty_slave_driver->other = pty_driver; @@ -366,6 +370,8 @@ static void __init unix98_pty_init(void) ptm_driver->init_termios.c_oflag = 0; ptm_driver->init_termios.c_cflag = B38400 | CS8 | CREAD; ptm_driver->init_termios.c_lflag = 0; + ptm_driver->init_termios.c_ispeed = 38400; + ptm_driver->init_termios.c_ospeed = 38400; ptm_driver->flags = TTY_DRIVER_RESET_TERMIOS | TTY_DRIVER_REAL_RAW | TTY_DRIVER_DYNAMIC_DEV | TTY_DRIVER_DEVPTS_MEM; ptm_driver->other = pts_driver; @@ -381,6 +387,8 @@ static void __init unix98_pty_init(void) pts_driver->subtype = PTY_TYPE_SLAVE; pts_driver->init_termios = tty_std_termios; pts_driver->init_termios.c_cflag = B38400 | CS8 | CREAD; + pts_driver->init_termios.c_ispeed = 38400; + pts_driver->init_termios.c_ospeed = 38400; pts_driver->flags = TTY_DRIVER_RESET_TERMIOS | TTY_DRIVER_REAL_RAW | TTY_DRIVER_DYNAMIC_DEV | TTY_DRIVER_DEVPTS_MEM; pts_driver->other = ptm_driver; -- cgit v1.2.3-18-g5258
