NAME

libfwup - library to support management of system firmware updates

SYNOPSIS

#include <fwup.h>

int fwup_supported(void);
− test if firmware updating is supported on the running machine

typedef struct fwup_resource_s fwup_resource;
typedef struct fwup_resource_iter_s
fwup_resource_iter;

int fwup_resource_iter_create(fwup_resource_iter **iter);
int
fwup_resource_iter_next(fwup_resource_iter *iter,

fwup_resource **re);

int fwup_resource_iter_destroy(fwup_resource_iter **iter);
− iterate the list of updateable firmware images

int fwup_set_up_update(fwup_resource *re, uint64_t hw_inst, int infd);
int
fwup_clear_status(fwup_resource *re);
int
fwup_get_guid(fwup_resource *re, efi_guid_t **guid);
int
fwup_get_fw_version(fwup_resource *re, uint32_t *version);
int
fwup_get_fw_type(fwup_resource *re, uint32_t *type);
int
fwup_get_lowest_supported_fw_version(fwup_resource *re,

uint32_t *version);

int fwup_get_last_attempt_info(fwup_resource *re, uint32_t *version,

uint32_t *status, time_t *when);

− operate on an individual firmware entry

DESCRIPTION

int fwup_supported(void);
Tests if the current machine supports firmware updates

typedef struct fwup_resource_s fwup_resource;
typedef struct fwup_resource_iter_s
fwup_resource_iter;

int fwup_resource_iter_create(fwup_resource_iter **iter);
Create a new firmware resoure iterator iter.

int fwup_resource_iter_next(fwup_resource_iter *iter,

fwup_resource **re);

Get the next firmware resource re from iterator iter.

int fwup_resource_iter_destroy(fwup_resource_iter **iter);
Destroy firmware resource iterator iter.

int fwup_set_up_update(fwup_resource *re, uint64_t hw_inst, int infd);
Set up an update for resource re, hardware instance number hw_inst,
with the file referenced by the file descriptor infd. infd must
support read(3).

int fwup_clear_status(fwup_resource *re);
Clear the status of the firmware resource re. This removes any pending
attempt to update it, as well as clearing any pending error report.

int fwup_get_guid(fwup_resource *re, efi_guid_t **guid);
Set guid to the GUID which uniquely identifies firmware resource re.

int fwup_get_fw_version(fwup_resource *re, uint32_t *version);
Set version to the version of the firmware resource re.

#define FWUP_RESOURCE_TYPE_UNKNOWN 0
#define FWUP_RESOURCE_TYPE_SYSTEM_FIRMWARE 1
#define FWUP_RESOURCE_TYPE_DEVICE_FIRMWARE 2
#define FWUP_RESOURCE_TYPE_UEFI_DRIVER 3
int
fwup_get_fw_type(fwup_resource *re, uint32_t *type);
Set type to the type of the firmware resource re.

int fwup_get_lowest_supported_fw_version(fwup_resource *re,

uint32_t *version);

Set version to the lowest firmware version resource re can be
updated to.

int fwup_get_last_attempt_info(fwup_resource *re, uint32_t *version,

uint32_t *status, time_t *when);

Get the status for the last attempt to update firmware resource re.
