Class
FwupdPluginCfiDevice
Description [src]
class FwupdPlugin.CfiDevice : FwupdPlugin.Device {
parent_instance: FuDevice
}
A chip conforming to the Common Flash Memory Interface, typically a SPI flash chip.
Where required, the quirks instance IDs will be added in ->setup()
.
The defaults are set as follows, and can be overridden in quirk files:
PageSize
: 0x100SectorSize
: 0x1000BlockSize
: 0x10000

Instance methods
fu_cfi_device_chip_select_locker_new
Creates a custom device locker that asserts and deasserts the chip select signal.
Available since: 1.8.0
fu_cfi_device_get_block_size
Gets the chip block size. This is typically the largest erasable block size.
Available since: 1.7.4
fu_cfi_device_get_page_size
Gets the chip page size. This is typically the largest writable block size.
Available since: 1.7.3
fu_cfi_device_get_sector_size
Gets the chip sector size. This is typically the smallest erasable page size.
Available since: 1.7.3
fu_cfi_device_send_command
Sends an unspecified command stream to the CFI device.
Available since: 1.9.1
fu_cfi_device_set_block_size
Sets the chip block size. This is typically the largest erasable chunk size.
Available since: 1.7.4
fu_cfi_device_set_page_size
Sets the chip page size. This is typically the largest writable block size.
Available since: 1.7.3
fu_cfi_device_set_sector_size
Sets the chip sector size. This is typically the smallest erasable page size.
Available since: 1.7.3
Methods inherited from FuDevice (162)
fu_device_activate
Activates up a device, which normally means the device switches to a new firmware version. This should only be called when data loss cannot occur.
Available since: 1.2.6
fu_device_add_child
Sets any child device. An child device is logically linked to the primary device in some way.
Available since: 1.0.8
fu_device_add_counterpart_guid
Adds a GUID to the device. If the guid
argument is not a valid GUID then it
is converted to a GUID using fwupd_guid_hash_string()
.
Available since: 1.1.2
fu_device_add_flag
Adds a device flag to the device.
Available since: 0.1.0
fu_device_add_guid
Adds a GUID to the device. If the guid
argument is not a valid GUID then it
is converted to a GUID using fwupd_guid_hash_string()
.
Available since: 0.7.2
fu_device_add_guid_full
Adds a GUID to the device. If the guid
argument is not a valid GUID then it
is converted to a GUID using fwupd_guid_hash_string()
.
Available since: 1.6.2
fu_device_add_instance_id
Adds an instance ID to the device. If the instance_id
argument is already a
valid GUID then fu_device_add_guid()
should be used instead.
Available since: 1.2.5
fu_device_add_instance_id_full
Adds an instance ID with all parameters set.
Available since: 1.2.9
fu_device_add_instance_str
Assign a value for the key
.
Available since: 1.7.7
fu_device_add_instance_strsafe
Assign a sanitized value for the key
.
Available since: 1.7.7
fu_device_add_instance_strup
Assign a uppercase value for the key
.
Available since: 1.7.7
fu_device_add_instance_u16
Assign a value to the key
, which is padded as 4X
.
Available since: 1.7.7
fu_device_add_instance_u32
Assign a value to the key
, which is padded as 8X
.
Available since: 1.7.7
fu_device_add_instance_u4
Assign a value to the key
, which is padded as 1X
.
Available since: 1.7.7
fu_device_add_instance_u8
Assign a value to the key
, which is padded as 2X
.
Available since: 1.7.7
fu_device_add_internal_flag
Adds a private flag that stays internal to the engine and is not leaked to the client.
Available since: 1.5.5
fu_device_add_parent_backend_id
Sets any parent device using the physical ID. An parent device is logically
linked to the primary device in some way and can be added before or after self
.
Available since: 1.9.7
fu_device_add_parent_guid
Sets any parent device using a GUID. An parent device is logically linked to
the primary device in some way and can be added before or after self
.
Available since: 1.0.8
fu_device_add_parent_physical_id
Sets any parent device using the physical ID. An parent device is logically
linked to the primary device in some way and can be added before or after self
.
Available since: 1.6.2
fu_device_add_possible_plugin
Adds a plugin name to the list of plugins that might be able to handle this device. This is typically called from a quirk handler.
Available since: 1.5.1
fu_device_add_private_flag
Adds a private flag that can be used by the plugin for any purpose.
Available since: 1.6.2
fu_device_add_problem
Prevent the device from being updated, changing it from FWUPD_DEVICE_FLAG_UPDATABLE
to FWUPD_DEVICE_FLAG_UPDATABLE_HIDDEN
if not already inhibited.
Available since: 1.8.1
fu_device_add_security_attrs
Adds HSI security attributes.
