# /bin/echo 1,2,3,4 > cpuset.cpus -> set cpus list to cpus 1,2,3,4
|
||||
|
||||
To add a CPU to a cpuset, write the new list of CPUs including the
|
||||
CPU to be added. To add 6 to the above cpuset:
|
||||
|
||||
# /bin/echo 1-4,6 > cpus -> set cpus list to cpus 1,2,3,4,6
|
||||
# /bin/echo 1-4,6 > cpuset.cpus -> set cpus list to cpus 1,2,3,4,6
|
||||
|
||||
Similarly to remove a CPU from a cpuset, write the new list of CPUs
|
||||
without the CPU to be removed.
|
||||
|
||||
To remove all the CPUs:
|
||||
|
||||
# /bin/echo "" > cpus -> clear cpus list
|
||||
# /bin/echo "" > cpuset.cpus -> clear cpus list
|
||||
|
||||
2.3 Setting flags
|
||||
-----------------
|
||||
|
||||
The syntax is very simple:
|
||||
|
||||
# /bin/echo 1 > cpu_exclusive -> set flag 'cpu_exclusive'
|
||||
# /bin/echo 0 > cpu_exclusive -> unset flag 'cpu_exclusive'
|
||||
# /bin/echo 1 > cpuset.cpu_exclusive -> set flag 'cpuset.cpu_exclusive'
|
||||
# /bin/echo 0 > cpuset.cpu_exclusive -> unset flag 'cpuset.cpu_exclusive'

version of tty_name, and rename the reentrant _tty_name

function to be tty_name.

|
||||
tty_get_baud_rate().
|
||||
|
||||
* tty_io.c (tty_get_baud_rate): New function which computes the
|
||||
correct baud rate for the tty. 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 16550As being
|
||||
detected as 16750s. Hopefully 16750s will still be
|
||||
detected as 16750, and other weird UARTs 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 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

to support BSD ioctls to set and clear the break
|
||||
condition explicitly.
|
||||
|
||||
* console.c (scrup, scrdown, insert_line, delete_line): Applied
|
||||
fix suggested by Aaron Tiensivu to speed up block scrolls
|
||||
up and down.
|
||||
|
||||
* n_tty.c (opost_block, write_chan): Added a modified "fast
|
||||
console" patch which processes a block of text via
|
||||
"cooking" efficiently.

Hawes to prevent race conditions in the tty code.
|

|
||||
* n_tty.c (n_tty_chars_in_buffer): Applied fix suggested by Bill
|
||||
Hawes so that n_tty_chars_in_buffer returns the correct
|

value in the case when the tty is in cannonical mode. (To
|
||||
avoid a pty deadlock with telnetd.)

* serial.c (change_speed): Add support for the termios flag
|

CMSPAR, which allows the user to select stick parity.

|
||||

* serial.c (rs_init): Don't autoconfig a device if the I/O region
|
||||
is already reserved.

||||
|

* serial.c (serial_proc_info): Add support for /proc/serial.

Thu Feb 13 00:49:10 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
|

|

* serial.c (receive_chars): When the UART repotrs an overrun
|
||||
condition, it does so with a valid character. Changed to
|
||||
not throw away the valid character, but instead report the
|
||||
overrun after the valid character.
|
||||
|
||||
* serial.c: Added new #ifdef's for some of the advanced serial
|
||||
driver features. A minimal driver that only supports COM
|
||||
1/2/3/4 without sharing serial interrupts only takes 17k;
|
||||
the full driver takes 32k.

|

restore_flags() in order to ensure we don't accidentally
|
||||
turn on interrupts when starting up the port.
|
||||
(startup): Move the insertion of serial structure into the
|
||||
IRQ chain earlier into the startup processing. Interrupts
|
||||
should be off this whole time, but we eventually will want
|
||||
to reduce this window.

Thu Nov 21 10:05:22 1996 Theodore Ts'o <tytso@localhost.mit.edu>
|
||||
|
||||
* tty_ioctl.c (tty_wait_until_sent): Always check the driver
|
||||
wait_until_ready routine, even if there are no characters
|
||||
in the xmit buffer. (There may be charactes in the device
|
||||
FIFO.)
|
||||
(n_tty_ioctl): Add new flag tty->flow_stopped which
|
||||
indicates whether the tty is stopped due to a request by
|
||||
the TCXONC ioctl (used by tcflow). If so, don't let an
|
||||
incoming XOFF character restart the tty. The tty can only
|
||||
be restarted by another TCXONC request.
|
||||
|
||||
* tty_io.c (start_tty): Don't allow the tty to be restarted if
|
||||
tty->flow_stopped is true.
|
||||
|
||||
* n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and
|
||||
IXANY is set, don't eat a character trying to restart the
|
||||
tty.
|
||||
|
||||
* serial.c (startup): Remove need for MCR_noint from the
|
||||
async_struct structure. Only turn on DTR and RTS if the
|
||||
baud rate is not zero.
|
||||
(change_speed): More accurately calculate the timeout
|
||||
value based on the word size. Move responsibility of
|
||||
hangup when speed becomes B0 to rs_set_termios()
|
||||
(set_serial_info): When changing the UART type set the
|
||||
current xmit_fifo_size as well as the permanent
|
||||
xmit_fifo_size.
|
||||
(rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP
|
||||
ioctls to return EINTR if interrupted by a signal.
|
||||
(rs_set_termios): If the baud rate changes to or from B0,
|
||||
this function is now responsible for setting or clearing
|
||||
DTR and RTS. DTR and RTS are only be changed on the
|
||||
transition to or from the B0 state.
|
||||
(rs_close): Wait for the characters to drain based on
|
||||
info->timeout. At low baud rates (50 bps), it may take a
|
||||
long time for the FIFO to completely drain out!
|
||||
(rs_wait_until_sent): Fixed timeout handling. Now
|
||||
releases control to the scheduler, but checks frequently
|
||||
enough so that the function is sensitive enough to pass
|
||||
the timing requirements of the NIST-PCTS.
|
||||
(block_til_ready): When opening the device, don't turn on
|
||||
DTR and RTS if the baud rate is B0.
|
||||
|
||||
Thu Nov 14 00:06:09 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c (autoconfig): Fix autoconfiguration problems;
|
||||
info->flags wasn't getting initialized from the state
|
||||
structure. Put in more paranoid test for the 16750.
|
||||
|
||||
Fri Nov 8 20:19:50 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if
|
||||
the tty was previous throttled.
|
||||
(n_tty_set_termios, write_chan): Add changes suggested by
|
||||
Simon P. Allen to allow hardware cooking.
|
||||
|
||||
* tty_ioctl.c (set_termios): If we get a signal while waiting for
|
||||
the tty to drain, return -EINTR.
|
||||
|
||||
* serial.c (change_speed): Add support for CREAD, as required by
|
||||
POSIX.
|
||||
|
||||
Sat Nov 2 20:43:10 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c: Wholesale changes. Added support for the Startech
|
||||
16650 and 16650V2 chips. (WARNING: the new startech
|
||||
16650A may or may not work!) Added support for the
|
||||
TI16750 (not yet tested). Split async_struct into a
|
||||
transient part (async_struct) and a permanent part
|
||||
(serial_state) which contains the configuration
|
||||
information for the ports. Added new driver routines
|
||||
wait_until_sent() and send_xchar() to help with POSIX
|
||||
compliance. Added support for radio clocks which waggle
|
||||
the carrier detect line (CONFIG_HARD_PPS).
|
||||
|
||||
* tty_ioctl.c (tty_wait_until_sent): Added call to new driver
|
||||
function tty->driver.wait_until_sent(), which returns when
|
||||
the tty's device xmit buffers are drained. Needed for
|
||||
full POSIX compliance.
|
||||
|
||||
(send_prio_char): New function, called by the ioctl's
|
||||
TCIOFF and TCION; uses the new driver call send_xchar(),
|
||||
which will send the XON or XOFF character at high priority
|
||||
(and even if tty output is stopped).
|
||||
|
||||
Wed Jun 5 18:52:04 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* pty.c (pty_close): When closing a pty, make sure packet mode is
|
||||
cleared.
|
||||
|
||||
Sun May 26 09:33:52 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* vesa_blank.c (set_vesa_blanking): Add missing verify_area() call.
|
||||
|
||||
* selection.c (set_selection): Add missing verify_area() call.
|
||||
|
||||
* tty_io.c (tty_ioctl): Add missing verify_area() calls.
|
||||
|
||||
* serial.c (rs_ioctl): Add missing verify_area() calls.
|
||||
(rs_init): Allow initialization of serial driver
|
||||
configuration from a module.
|
||||
|
||||
* random.c (extract_entropy): Add missing verify_area call.
|
||||
Don't limit number of characters returned to
|
||||
32,768. Extract entropy is now no longer a inlined
|
||||
function.
|
||||
|
||||
(random_read): Check return value in case extract_entropy
|
||||
returns an error.
|
||||
|
||||
(secure_tcp_sequence_number): New function which returns a
|
||||
secure TCP sequence number. This is needed to prevent some
|
||||
nasty TCP hijacking attacks.
|
||||
|
||||
(init_std_data): Initialize using gettimeofday() instead of
|
||||
struct timeval xtime.
|
||||
|
||||
(fast_add_entropy_word, add_entropy_word): Rename the
|
||||
inline function add_entropy_word() to
|
||||
fast_add_entropy_word(). Make add_entropy_word() be the
|
||||
non-inlined function which is used in non-timing critical
|
||||
places, in order to save space.
|
||||
|
||||
(initialize_benchmark, begin_benchmark, end_benchmark): New
|
||||
functions defined when RANDOM_BENCHMARK is defined. They
|
||||
allow us to benchmark the speed of the
|
||||
add_timer_randomness() call.
|
||||
|
||||
(int_ln, rotate_left): Add two new inline functions with
|
||||
i386 optimized asm instructions. This speeds up the
|
||||
critical add_entropy_word() and add_timer_randomness()
|
||||
functions, which are called from interrupt handlers.
|
||||
|
||||
Tue May 7 22:51:11 1996 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* random.c (add_timer_randomness): Limit the amount randomness
|
||||
that we estimate to 12 bits. (An arbitrary amount).
|
||||
|
||||
(extract_entropy): To make it harder to analyze the hash
|
||||
function, fold the hash function in half using XOR, and
|
||||
use the folded result as the value to emit to the user.
|
||||
Also, add timer randomness each pass through the
|
||||
exact_entropy call, to increase the amount of unknown
|
||||
values during the extraction process.
|
||||
|
||||
(random_ioctl): Use IOR/IOW definitions to define the
|
||||
ioctl values used by the /dev/random driver. Allow the
|
||||
old ioctl values to be used for backwards compatibility
|
||||
(for a limited amount of time).
|
||||
|
||||
Wed Apr 24 14:02:04 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
|
||||
|
||||
* random.c (add_timer_randomness): Use 2nd derivative as well to
|
||||
better estimate entropy.
|
||||
|
||||
(rand_initialize): Explicitly initialize all the pointers
|
||||
to NULL. (Clearing pointers using memset isn't portable.)
|
||||
Initialize the random pool with OS-dependent data.
|
||||
|
||||
(random_write): Add sanity checking to the arguments to
|
||||
random_write(), so that bad arguments won't cause a kernel
|
||||
SEGV.
|
||||
|
||||
(random_read): Update the access time of the device inode
|
||||
when you return data to the user.
|
||||
|
||||
(random_ioctl): Wake up the random_wait channel when there
|
||||
are only WAIT_INPUT_BITS available. Add more paranoia
|
||||
checks to make sure entropy_count doesn't go beyond the
|
||||
bounds of (0, POOLSIZE). Add a few missing verify_area
|
||||
checks. Add support for the RNDCLEARPOOL ioctl, which
|
||||
zaps the random pool.
|
||||
|
||||
(add_timer_randomness): Wake up the random_wait
|
||||
channel only when there are WAIT_INPUT_BITS available.
|
||||
|
||||
(random_select): Allow a random refresh daemon process to
|
||||
select on /dev/random for writing; wake up the daemon when
|
||||
there are less than WAIT_OUTPUT_BITS bits of randomness
|
||||
available.
|
||||
|
||||
Tue Apr 23 22:56:07 1996 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* tty_io.c (init_dev): Change return code when user attempts to
|
||||
open master pty which is already open from EAGAIN to EIO,
|
||||
to match with BSD expectations. EIO is more correct
|
||||
anyway, since EAGAIN implies that retrying will be
|
||||
successful --- which it might be.... Eventually!!
|
||||
|
||||
* pty.c (pty_open, pty_close): Fix wait loop so that we don't
|
||||
busy loop while waiting for the master side to open.
|
||||
Fix tty opening/closing logic. TTY_SLAVE_CLOSED was
|
||||
renamed to TTY_OTHER_CLOSED, so that the name is more
|
||||
descriptive. Also fixed code so that the tty flag
|
||||
actually works correctly now....
|
||||
|
||||
Mon Apr 1 10:22:01 1996 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c (rs_close): Cleaned up modularization changes.
|
||||
Remove code which forced line discipline back to N_TTY
|
||||
this is done in the tty upper layers, and there's no
|
||||
reason to do it here. (Making this change also
|
||||
removed the requirement that the serial module access
|
||||
the internal kernel symbol "ldiscs".)
|
||||
|
||||
* tty_io.c (tty_init): Formally register a tty_driver entry for
|
||||
/dev/tty (device 4, 0) and /dev/console (device 5, 0).
|
||||
This guarantees that major device numbers 4 and 5 will be
|
||||
reserved for the tty subsystem (as they have to be because
|
||||
of /dev/tty and /dev/console). Removed tty_regdev, as
|
||||
this interface is no longer necessary.
|
||||
|
||||
Sun Mar 17 20:42:47 GMT 1996 <ah@doc.ic.ac.uk>
|
||||
|
||||
* serial.c : modularisation (changes in linux/fs/device.c allow
|
||||
kerneld to automatically load the serial module).
|
||||
|
||||
* Makefile, Config.in : serial modularisation adds.
|
||||
|
||||
* tty_io.c : tty_init_ctty used by to register "cua" driver just
|
||||
for the /dev/tty device (5,0). Added tty_regdev.
|
||||
|
||||
* serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes
|
||||
waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO
|
||||
if no change was done since the time of call.
|
||||
|
||||
Sat Mar 16 14:33:13 1996 <aeb@cwi.nl>
|
||||
|
||||
* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
|
||||
exit, do not perform an implicit vhangup on a pty.
|
||||
|
||||
Fri Feb 9 14:15:47 1996 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c (block_til_ready): Fixed another race condition which
|
||||
happens if a hangup happens during the open.
|
||||
|
||||
Wed Jan 10 10:08:00 1996 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c (block_til_ready): Remove race condition which happened
|
||||
if a hangup condition happened during the setup of the
|
||||
UART, before rs_open() called block_til_ready(). This
|
||||
caused the info->count counter to be erroneously
|
||||
decremented.
|
||||
|
||||
* serial.c (startup, rs_open): Remove race condition that could
|
||||
cause a memory leak of one page. (Fortunately, both race
|
||||
conditions were relatively rare in practice.)
|
||||
|
||||
Tue Dec 5 13:21:27 1995 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* serial.c (check_modem_status, rs_ioctl): Support the new
|
||||
ioctl()'s TIOCGICOUNT, TIOCMIWAIT. These allow an
|
||||
application program to wait on a modem serial register
|
||||
status bit change, and to find out how many changes have
|
||||
taken place for the MSR bits.
|
||||
|
||||
(rs_write): Eliminate a race condition which is introduced
|
||||
if it is necessary to wait for the semaphore.
|
||||
|
||||
Sat Nov 4 17:14:45 1995 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* tty_io.c (tty_init): Move registration of TTY_MAJOR and
|
||||
TTY_AUX_MAJOR to the end, so that /proc/devices looks
|
||||
prettier.
|
||||
|
||||
* pty.c (pty_init): Use new major numbers for PTY master and slave
|
||||
devices. This allow us to have more than 64 pty's. We
|
||||
register the old pty devices for backwards compatibility.
|
||||
Note that a system should either be using the old pty
|
||||
devices or the new pty devices --- in general, it should
|
||||
try to use both, since they map into the same pty table.
|
||||
The old pty devices are strictly for backwards compatibility.
|
||||
|
||||
Wed Oct 11 12:45:24 1995 <tytso@rsts-11.mit.edu>
|
||||
|
||||
* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
|
||||
exit, perform an implicit vhangup on the tty.
|
||||
|
||||
* pty.c (pty_close): When the master pty is closed, send a hangup
|
||||
to the slave pty.
|
||||
(pty_open): Use the flag TTY_SLAVE_CLOSED to test to see
|
||||
if there are any open slave ptys, instead of using
|
||||
tty->link->count. The old method got confused if there
|
||||
were processes that had hung-up file descriptors on the
|
||||
slave tty.
|
||||
|
||||
Tue May 2 00:53:25 1995 <tytso@rsx-11.mit.edu>
|
||||
|
||||
* tty_io.c (tty_set_ldisc): Wait until the output buffer is
|
||||
drained before closing the old line discipline --- needed
|
||||
in only one case: XON/XOFF processing.
|
||||
|
||||
* n_tty.c (n_tty_close): Don't bother waiting until the output
|
||||
driver is closed; in general, the line discipline
|
||||
shouldn't care if the hardware is finished
|
||||
transmitting before the line discipline terminates.
|
||||
|
||||
* tty_io.c (release_dev): Shutdown the line discipline after
|
||||
decrementing the tty count variable; but set the
|
||||
TTY_CLOSING flag so that we know that this tty structure
|
||||
isn't long for this world.
|
||||
|
||||
* tty_io.c (init_dev): Add sanity code to check to see if
|
||||
TTY_CLOSING is set on a tty structure; if so, something
|
||||
bad has happened (probably a line discipline close blocked
|
||||
when it shouldn't have; so do a kernel printk and then
|
||||
return an error).
|
||||
|
||||
Wed Apr 26 10:23:44 1995 Theodore Y. Ts'o <tytso@localhost>
|
||||
|
||||
* tty_io.c (release_dev): Try to shutdown the line discipline
|
||||
*before* decrementing the tty count variable; this removes
|
||||
a potential race condition which occurs when the line
|
||||
discipline close blocks, and another process then tries
|
||||
open the same serial port.
|
||||
|
||||
* serial.c (rs_hangup): When hanging up, flush the output buffer
|
||||
before shutting down the UART. Otherwise the line
|
||||
discipline close blocks waiting for the characters to get
|
||||
flushed, which never happens until the serial port gets reused.
|
||||
|
||||
Wed Apr 12 08:06:16 1995 Theodore Y. Ts'o <tytso@localhost>
|
||||
|
||||
* serial.c (do_serial_hangup, do_softint, check_modem_status,
|
||||
rs_init): Hangups are now scheduled via a separate tqueue
|
||||
structure in the async_struct structure, tqueue_hangup.
|
||||
This task is pushed on to the tq_schedule queue, so that
|
||||
it is processed synchronously by the scheduler.
|
||||
|
||||
Sat Feb 18 12:13:51 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear
|
||||
current->tty_old_pgrp field when a session leader
|
||||
acquires a controlling tty, and after a session leader
|
||||
has disassociated from a controlling tty.
|
||||
|
||||
Fri Feb 17 09:34:09 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi):
|
||||
Change the number of passes made from 64 to be 256,
|
||||
configurable with the #define RS_ISR_PASS_LIMIT.
|
||||
|
||||
* serial.c (rs_init, set_serial_info, get_serial_info, rs_close):
|
||||
Remove support for closing_wait2. Instead, set
|
||||
tty->closing and rely on the line discipline to prevent
|
||||
echo wars.
|
||||
|
||||
* n_tty.c (n_tty_receive_char): IEXTEN does not need to be
|
||||
enabled in order for IXANY to be active.
|
||||
|
||||
If tty->closing is set, then only process XON and XOFF
|
||||
characters.
|
||||
|
||||
Sun Feb 12 23:57:48 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_timer): Change the interrupt poll time from 60
|
||||
seconds to 10 seconds, configurable with the #define
|
||||
RS_STROBE_TIME.
|
||||
|
||||
* serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl,
|
||||
set_multiport_struct, get_multiport_struct): Add
|
||||
provisions for a new type of interrupt service routine,
|
||||
which better supports multiple serial ports on a single
|
||||
IRQ.
|
||||
|
||||
Sun Feb 5 19:35:11 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent):
|
||||
* serial.c (rs_ioctl, rs_close):
|
||||
* cyclades.c (cy_ioctl, cy_close):
|
||||
* n_tty.c (n_tty_close): Rename wait_until_sent to
|
||||
tty_wait_until_sent, so that it's a better name to export
|
||||
in ksyms.c.
|
||||
|
||||
Sat Feb 4 23:36:20 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_close): Added missing check for closing_wait2 being
|
||||
ASYNC_CLOSING_WAIT_NONE.
|
||||
|
||||
Thu Jan 26 09:02:49 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_init, set_serial_info, get_serial_info,
|
||||
rs_close): Support close_wait in the serial driver.
|
||||
This is helpful for slow devices (like serial
|
||||
plotters) so that their outputs don't get flushed upon
|
||||
device close. This has to be configurable because
|
||||
normally we don't want ports to be hung up for long
|
||||
periods of time during a close when they are not
|
||||
connected to a device, or the device is powered off.
|
||||
|
||||
The default is to wait 30 seconds; in the case of a
|
||||
very slow device, the close_wait timeout should be
|
||||
lengthened. If it is set to 0, the kernel will wait
|
||||
forever for all of the data to be transmitted.
|
||||
|
||||
Thu Jan 17 01:17:20 1995 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (startup, change_speed, rs_init): Add support to detect
|
||||
the StarTech 16650 chip. Treat it as a 16450 for now,
|
||||
because of its FIFO bugs.
|
||||
|
||||
Thu Jan 5 21:21:57 1995 <dahinds@users.sourceforge.net>
|
||||
|
||||
* serial.c: (receive_char): Added counter to prevent infinite loop
|
||||
when a PCMCIA serial device is ejected.
|
||||
|
||||
Thu Dec 29 17:53:48 1994 <tytso@rsx-11.mit.edu>
|
||||
|
||||
* tty_io.c (check_tty_count): New procedure which checks
|
||||
tty->count to make sure that it matches with the number of
|
||||
open file descriptors which point at the structure. If
|
||||
the number doesn't match, it prints a warning message.
|
||||
|
||||
Wed Dec 28 15:41:51 1994 <tytso@rsx-11.mit.edu>
|
||||
|
||||
* tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time,
|
||||
save the tty's current foreground process group in the
|
||||
session leader's task structure. When the session leader
|
||||
terminates, send a SIGHUP, SIGCONT to that process group.
|
||||
This is not required by POSIX, but it's not prohibited
|
||||
either, and it appears to be the least intrusive way
|
||||
to fix a problem that dialup servers have with
|
||||
orphaned process groups caused by modem hangups.
|
||||
|
||||
Thu Dec 8 14:52:11 1994 <tytso@rsx-11.mit.edu>
|
||||
|
||||
* serial.c (rs_ioctl): Don't allow most ioctl's if the serial port
|
||||
isn't initialized.
|
||||
|
||||
* serial.c (rs_close): Don't clear the IER if the serial port
|
||||
isn't initialized.
|
||||
|
||||
* serial.c (block_til_ready): Don't try to block on the dialin
|
||||
port if the serial port isn't initialized.
|
||||
|
||||
Wed Dec 7 10:48:30 1994 Si Park (si@wimpol.demon.co.uk)
|
||||
* tty_io.c (tty_register_driver): Fix bug when linking onto
|
||||
the tty_drivers list. We now test that there are elements
|
||||
already on the list before setting the back link from the
|
||||
first element to the new driver.
|
||||
|
||||
* tty_io.c (tty_unregister_driver): Fix bug in unlinking the
|
||||
specified driver from the tty_drivers list. We were not
|
||||
setting the back link correctly. This used to result in
|
||||
a dangling back link pointer and cause panics on the next
|
||||
call to get_tty_driver().
|
||||
|
||||
Tue Nov 29 10:21:09 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (tty_unregister_driver): Fix bug in
|
||||
tty_unregister_driver where the pointer to the refcount is
|
||||
tested, instead of the refcount itself. This caused
|
||||
tty_unregister_driver to always return EBUSY.
|
||||
|
||||
Sat Nov 26 11:59:24 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (tty_ioctl): Add support for the new ioctl
|
||||
TIOCTTYGSTRUCT, which allow a kernel debugging program
|
||||
direct read access to the tty and tty_driver structures.
|
||||
|
||||
Fri Nov 25 17:26:22 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_set_termios): Don't wake up processes blocked in
|
||||
open when the CLOCAL flag changes, since a blocking
|
||||
open only samples the CLOCAL flag once when it blocks,
|
||||
and doesn't check it again. (n.b. FreeBSD has a
|
||||
different behavior for blocking opens; it's not clear
|
||||
whether Linux or FreeBSD's interpretation is correct.
|
||||
POSIX doesn't give clear guidance on this issue, so
|
||||
this may change in the future....)
|
||||
|
||||
* serial.c (block_til_ready): Use the correct termios structure to
|
||||
check the CLOCAL flag. If the cuaXX device is active,
|
||||
then check the saved termios for the ttySXX device.
|
||||
Otherwise, use the currently active termios structure.
|
||||
|
||||
Sun Nov 6 21:05:44 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (change_speed): Add support for direct access of
|
||||
57,600 and 115,200 bps.
|
||||
|
||||
Wed Nov 2 10:32:36 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* n_tty.c (n_tty_receive_room): Only allow excess characters
|
||||
through if we are in ICANON mode *and* there are other no
|
||||
pending lines in the buffer. Otherwise cut and paste over
|
||||
4k breaks.
|
||||
|
||||
Sat Oct 29 18:17:34 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne
|
||||
Riiber so that user mode programs can tell when the
|
||||
transmitter shift register is empty.
|
||||
|
||||
Thu Oct 27 23:14:29 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_ioctl.c (wait_until_sent): Added debugging printk statements
|
||||
(under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT)
|
||||
|
||||
* serial.c (rs_interrupt, rs_interrupt_single, receive_chars,
|
||||
change_speed, rs_close): rs_close now disables receiver
|
||||
interrupts when closing the serial port. This allows the
|
||||
serial port to close quickly when Linux and a modem (or a
|
||||
mouse) are engaged in an echo war; when closing the serial
|
||||
port, we now first stop listening to incoming characters,
|
||||
and *then* wait for the transmit buffer to drain.
|
||||
|
||||
In order to make this change, the info->read_status_mask
|
||||
is now used to control what bits of the line status
|
||||
register are looked at in the interrupt routine in all
|
||||
cases; previously it was only used in receive_chars to
|
||||
select a few of the status bits.
|
||||
|
||||
Mon Oct 24 23:36:21 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_close): Add a timeout to the transmitter flush
|
||||
loop; this is just a sanity check in case we have flaky
|
||||
(or non-existent-but-configured-by-the-user) hardware.
|
||||
|
||||
Fri Oct 21 09:37:23 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the
|
||||
process or process group has not be specified yet, set it
|
||||
to be the tty's process group, or if that is not yet set,
|
||||
to the current process's pid.
|
||||
|
||||
Thu Oct 20 23:17:28 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* n_tty.c (n_tty_receive_room): If we are doing input
|
||||
canonicalization, let as many characters through as
|
||||
possible, so that the excess characters can be "beeped".
|
||||
|
||||
Tue Oct 18 10:02:43 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_start): Removed an incorrect '!' that was
|
||||
preventing transmit interrupts from being re-enabled in
|
||||
rs_start(). Fortunately in most cases it would be
|
||||
re-enabled elsewhere, but this still should be fixed
|
||||
correctly.
|
||||
|
||||
Sun Oct 9 23:46:03 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (do_tty_hangup): If the tty driver flags
|
||||
TTY_DRIVER_RESET_TERMIOS is set, then reset the termios
|
||||
settings back to the driver's initial configuration. This
|
||||
allows the termios settings to be reset even if a process
|
||||
has hung up file descriptors keeping a pty's termios from
|
||||
being freed and reset.
|
||||
|
||||
* tty_io.c (release_dev): Fix memory leak. The pty's other
|
||||
termios structure should also be freed.
|
||||
|
||||
* serial.c (rs_close, shutdown): Change how we wait for the
|
||||
transmitter to completely drain before shutting down the
|
||||
serial port. We now do it by scheduling in another
|
||||
process instead of busy looping with the interrupts turned
|
||||
on. This may eliminate some race condition problems that
|
||||
some people seem to be reporting.
|
||||
|
||||
Sun Sep 25 14:18:14 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (release_dev): When freeing a tty make sure that both
|
||||
the tty and the o_tty (if present) aren't a process's
|
||||
controlling tty. (Previously, we only checked the tty.)
|
||||
|
||||
* serial.c (change_speed): Only enable the Modem Status
|
||||
Interrupt for a port if CLOCAL is not set or CRTSCTS
|
||||
is set. If we're not checking the carrier detect and
|
||||
CTS line, there's no point in enabling the modem
|
||||
status interrupt. This will save spurious interrupts
|
||||
from slowing down systems who have terminals that
|
||||
don't support either line. (Of course, if you want
|
||||
only one of CD and CTS support, you will need a
|
||||
properly wired serial cable.)
|
||||
|
||||
Thu Sep 22 08:32:48 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (do_SAK): Return if tty is null.
|
||||
|
||||
* tty_io.c (_tty_name): Return "NULL tty" if the passed in tty is
|
||||
NULL.
|
||||
|
||||
Sat Sep 17 13:19:25 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_ioctl.c (n_tty_ioctl): Fix TIOCGLCKTRMIOS and
|
||||
TIOCSLCKTRMIOS, which were totally broken. Remove
|
||||
extra indirection from argument; it should be a struct
|
||||
termios *, not a struct termios **.
|
||||
&real_tty->termios_locked should have been
|
||||
real_tty->termios_locked. This caused us to be
|
||||
reading and writing the termios_locked structure to
|
||||
random places in kernel memory.
|
||||
|
||||
* tty_io.c (release_dev): Oops! Forgot to delete a critical kfree
|
||||
of the locked_termios. This leaves the locked_termios
|
||||
structure pointed at a freed object.
|
||||
|
||||
Fri Sep 16 08:13:25 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* tty_io.c (tty_open): Don't check for an exclusive open until
|
||||
after the device specific open routine has been called.
|
||||
Otherwise, the serial device ref counting will be screwed
|
||||
up.
|
||||
|
||||
* serial.c (rs_open, block_til_ready): Don't set termios structure
|
||||
until after block_til_ready has returned successfully.
|
||||
Modify block_til_ready to check the normal_termios
|
||||
structure directly, so it doesn't rely on termios being
|
||||
set before it's called.
|
||||
|
||||
Thu Sep 15 23:34:01 1994 Theodore Y. Ts'o (tytso@rt-11)
|
||||
|
||||
* serial.c (rs_close): Turn off interrupts during rs_close() to
|
||||
prevent a race condition with the hangup code (which
|
||||
runs during a software interrupt).
|
||||
