More factoring out of + common code out of the serial driver to the high-level tty + functions.... + +Sat Nov 22 07:53:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> + + * serial.c, esp.c, rocket.c: Add tty->driver.break() routine, and + allow high-level tty code to handle the break and soft + carrier ioctls. + + * tty_ioctl.c (n_tty_ioctl): Support TIOCGSOFTCAR and + TIOCSSOFTCAR, so that device drivers don't have to support + it. + + * serial.c (autoconfig): Change 16750 test to hopefully eliminate + false results by people with strange 16550A's being + detected as 16750's. Hopefully 16750's will still be + detected as 16750, and other wierd UART's won't get poorly + autodetected. If this doesn't work, I'll have to disable + the auto identification for the 16750.... + + * tty_io.c (tty_hangup): Now do actually do the tty hangup + processing during the timer processing, and disable + interrupts while doing the hangup processing. This avoids + several nasty race conditions which happened when the + hangup processing was done asynchronously. + (tty_ioctl): Do break handling in the tty driver if + driver's break function is supported. + (tty_flip_buffer_push): New exported function which should + be used by drivers to push characters in the flip buffer + to the tty handler. This may either be done using a task + queue function for better CPU efficiency, or directly for + low latency operation. + + * serial.c (rs_set_termios): Fix bug rs_set_termios when + transitioning away from B0, submitted by Stanislav + Voronyi. + Thu Jun 19 20:05:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> * serial.c (begin_break, end_break, rs_ioctl): Applied patch |
