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: 0x100
SectorSize: 0x1000
BlockSize: 0x10000

Methods inherited from FuDevice (156)

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

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

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
