dmi_system_reset
Synopsis
#include <opendmi/entity/system-reset.h>
typedef struct dmi_system_reset {
bool is_enabled;
dmi_boot_option_t boot_on_watchdog;
dmi_boot_option_t boot_on_limit;
bool has_watchdog;
unsigned short reset_count;
unsigned short reset_limit;
unsigned short timer_interval;
unsigned short timeout;
} dmi_system_reset_t;Description
The dmi_system_reset_t structure holds the decoded system reset structure
(type 23) of SMBIOS, which describes the automatic system reset function. If
the system has a watchdog timer, and the timer is not reset within its
interval, the system resets itself and boots as boot_on_watchdog says. Once
the resets reach their limit, the system does what boot_on_limit says
instead.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(system_reset), and lives as long as the context it has been decoded
in.
Fields
is_enabled-
trueif the user has enabled the system reset. boot_on_watchdog-
What the system does after a watchdog reset, see
dmi_boot_option. boot_on_limit-
What the system does when the reset limit is reached, see
dmi_boot_option. has_watchdog-
trueif the system has a watchdog timer. reset_count-
Number of automatic system resets since the last intentional reset, or
USHRT_MAXif unknown. reset_limit-
Number of consecutive times the system reset is attempted, or
USHRT_MAXif unknown. timer_interval-
Interval of the watchdog timer, in minutes: if the timer is not reset within it, the system reset timeout starts.
USHRT_MAXif unknown. timeout-
Number of minutes before the reboot starts, after a power cycle, a local or remote system reset, or an automatic system reset.
USHRT_MAXif unknown.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(system_reset), false);
dmi_system_reset_t *reset = dmi_entity_info(entity,
DMI_TYPE(system_reset));
if ((reset != nullptr) && reset->is_enabled)
printf("on watchdog reset: %s\n",
dmi_boot_option_name(reset->boot_on_watchdog));
