* Rules to follow when using local atomic operations
- Variables touched by local ops must be per cpu variables.
- _Only_ the CPU owner of these variables must write to them.
- This CPU can use local ops from any context (process, irq, softirq, nmi, ...)
to update its local_t variables.
- Preemption (or interrupts) must be disabled when using local ops in
process context to make sure the process won't be migrated to a
different CPU between getting the per-cpu variable and doing the
actual local op.
- When using local ops in interrupt context, no special care must be
taken on a mainline kernel, since they will run on the local CPU with
preemption already disabled. I suggest, however, to explicitly
disable preemption anyway to make sure it will still work correctly on
-rt kernels.
- Reading the local cpu variable will provide the current copy of the
variable.
- Reads of these variables can be done from any CPU, because updates to
"long", aligned, variables are always atomic. Since no memory
synchronization is done by the writer CPU, an outdated copy of the
variable can be read when reading some _other_ cpu's variables.
* Rules to follow when using local atomic operations
- Variables touched by local ops must be per cpu variables.

@ -42,23 +42,27 @@ like this source file: see Documentation/watchdog/src/watchdog-simple.c
A more advanced driver could for example check that a HTTP server is
still responding before doing the write call to ping the watchdog.
When the device is closed, the watchdog is disabled. This is not
always such a good idea, since if there is a bug in the watchdog
daemon and it crashes the system will not reboot. Because of this,
some of the drivers support the configuration option "Disable watchdog
shutdown on close", CONFIG_WATCHDOG_NOWAYOUT. If it is set to Y when
compiling the kernel, there is no way of disabling the watchdog once
it has been started. So, if the watchdog daemon crashes, the system
will reboot after the timeout has passed. Watchdog devices also usually
support the nowayout module parameter so that this option can be controlled
at runtime.
When the device is closed, the watchdog is disabled, unless the "Magic
Close" feature is supported (see below). This is not always such a
good idea, since if there is a bug in the watchdog daemon and it
crashes the system will not reboot. Because of this, some of the
drivers support the configuration option "Disable watchdog shutdown on
close", CONFIG_WATCHDOG_NOWAYOUT. If it is set to Y when compiling
the kernel, there is no way of disabling the watchdog once it has been
started. So, if the watchdog daemon crashes, the system will reboot
after the timeout has passed. Watchdog devices also usually support
the nowayout module parameter so that this option can be controlled at
runtime.
Drivers will not disable the watchdog, unless a specific magic character 'V'
has been sent /dev/watchdog just before closing the file. If the userspace
daemon closes the file without sending this special character, the driver
will assume that the daemon (and userspace in general) died, and will stop
pinging the watchdog without disabling it first. This will then cause a
reboot if the watchdog is not re-opened in sufficient time.
Magic Close feature:
If a driver supports "Magic Close", the driver will not disable the
watchdog unless a specific magic character 'V' has been sent to
/dev/watchdog just before closing the file. If the userspace daemon
closes the file without sending this special character, the driver
will assume that the daemon (and userspace in general) died, and will
stop pinging the watchdog without disabling it first. This will then
cause a reboot if the watchdog is not re-opened in sufficient time.

*! Revision 1.18 2005/01/24 09:11:26 mikaelam
*! Minor changes to get DS1302 RTC chip driver to work
*!
*! Revision 1.17 2005/01/05 06:11:22 starvik
*! No need to do local_irq_disable after local_irq_save.
*!
*! Revision 1.16 2004/12/13 12:21:52 starvik

*!
*! Revision 1.4 2002/12/11 13:13:57 starvik
*! Added arch/ to v10 specific includes
*! Added fix from Linux 2.4 in serial.c (flush_to_flip_buffer)
*!
*! Revision 1.3 2002/11/20 11:56:10 starvik
*! Merge of Linux 2.5.48
*!
*! Revision 1.2 2002/11/18 13:16:06 starvik
*! Linux 2.5 port of latest 2.4 drivers
*!
*! Revision 1.15 2002/10/11 16:14:33 johana

*! Moved probe function closer to init function and marked it __init.
*!
*! Revision 1.11 2001/06/14 12:35:52 jonashg
*! The ATA hack is back. It is unfortunately the only way to set g27 to output.
*!
*! Revision 1.9 2001/06/14 10:00:14 jonashg
*! No need for tempudelay to be inline anymore (had to adjust the usec to
*! loops conversion because of this to make it slow enough to be a udelay).
*!
*! Revision 1.8 2001/06/14 08:06:32 jonashg
*! Made tempudelay delay usecs (well, just a tad more).
*!
*! Revision 1.7 2001/06/13 14:18:11 jonashg
*! Only allow processes with SYS_TIME capability to set time and charge.
*!

*! * Removed comment about /proc (nothing is exported there).
*!
*! Revision 1.5 2001/06/12 14:35:13 jonashg
*! Gave the module a name and added it to printk's.
*!
*! Revision 1.4 2001/05/31 14:53:40 jonashg
*! Made tempudelay() inline so that the watchdog doesn't reset (see
*! function comment).
*!
*! Revision 1.3 2001/03/26 16:03:06 bjornw
*! Needs linux/config.h
*!
*! Revision 1.2 2001/03/20 19:42:00 bjornw

*!
*! Revision 1.1 2001/03/20 09:13:50 magnusmn
*! Linux 2.4 port

*!
*! Revision 1.6 1999/10/27 13:19:47 bjornw

*! /dev/rtc calls it now.
*!
*! Revision 1.5 1999/10/27 12:39:37 bjornw
*! Disabled superuser check. Anyone can now set the time.
*!
*! Revision 1.4 1999/09/02 13:27:46 pkj
*! Added shadow for R_PORT_PB_CONFIG.
*! Renamed port_g_shadow to port_g_data_shadow.
*!
*! Revision 1.3 1999/09/02 08:28:06 pkj
*! Made it possible to select either port PB or the generic port for the RST
*! signal line to the DS1302 RTC.
*! Also make sure the RST bit is configured as output on Port PB (if used).
*!
*! Revision 1.2 1999/09/01 14:47:20 bjornw
*! Added support for /dev/rtc operations with ioctl RD_TIME and SET_TIME to read
