Hi Richard, > When performing a suspend operation, the kernel brings all of the > non-boot CPUs offline, calling the hot plug notifiers with the flag, > CPU_TASKS_FROZEN, set in the action code. Similarly, during resume, > the CPUs are brought back online, but again the notifiers have the > FROZEN flag set. > > While some very few drivers really need to treat suspend/resume > specially, this driver unintentionally ignores the notifications. > > This patch changes the driver to disable the watchdog interrupt > whenever the CPU goes offline, and to enable it whenever the CPU goes > back online. As a result, the suspended state is no longer a special > case that leaves the watchdog active. > > Cc: Wim Van Sebroeck <wim@xxxxxxxxx> > Cc: Guenter Roeck <linux@xxxxxxxxxxxx> > Cc: linux-watchdog@xxxxxxxxxxxxxxx > Signed-off-by: Richard Cochran <rcochran@xxxxxxxxxxxxx> > --- > drivers/watchdog/octeon-wdt-main.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) This patch has been added to linux-watchdog-next.
