Struct KObjectStore 

pub struct KObjectStore {
    pub root: Arc<SimpleDirectory>,
    /* private fields */
}

Owner of all the KObjects in sysfs.

Holds strong references to the KObjects that are visible in sysfs. These objects are organized into hierarchies that make it easier to implement sysfs.

Fields

root: Arc<SimpleDirectory>

Root of the sysfs hierarchy.

Implementations

impl KObjectStore

pub fn init(&self, kernel: &Kernel)

pub fn platform_bus(&self) -> Bus

Device bus used for platform devices (/sys/bus/platform).

pub fn virtual_device(&self) -> Device

Root device used for virtual devices (/sys/devices/virtual).

pub fn platform_device(&self) -> Device

Root device used for platform devices (/sys/devices/platform).

pub fn system_device(&self) -> Device

Root device used for system devices (/sys/devices/system).

Subsystems such as cpu place their root device beneath this device.

pub fn soc_device(&self) -> Device

Bus device used for SoC peripheral devices (/sys/devices/platform/soc).

pub fn block_class(&self) -> Class

Device class used for block devices.

pub fn thermal_class(&self) -> Class

Device class used for thermal devices.

pub fn graphics_class(&self) -> Class

Device class used for graphics devices.

pub fn input_class(&self) -> Class

Device class used for input devices.

pub fn mem_class(&self) -> Class

Device class used for mem devices.

pub fn net_class(&self) -> Class

Device class used for net devices.

pub fn misc_class(&self) -> Class

Device class used for misc devices.

pub fn tty_class(&self) -> Class

Device class used for tty devices.

pub fn dma_heap_class(&self) -> Class

Device class used for dma_heap devices.

pub fn starnix_class(&self) -> Class

Incorrect device class.

This class exposes the name “starnix” to userspace, which is incorrect. Instead, devices should use a class that represents their usage rather than their implementation.

This class exists because a number of devices incorrectly use this class. We should fix those devices to report their proper class.

pub fn rtc_class(&self) -> Class

Real-time clock class.

Becomes /sys/class/rtc/....

pub fn get_or_create_bus(&self, name: &FsStr) -> Bus

Get a bus by name.

If the bus does not exist, this function will create it.

pub fn get_or_create_class(&self, name: &FsStr) -> Class

Get a class by name.

If the class does not exist, this function will create it.

pub fn class_with_dir( &self, name: &FsStr, build_directory: impl FnOnce(&SimpleDirectoryMutator), ) -> Class

Trait Implementations

impl Default for KObjectStore

fn default() -> Self

Returns the “default value” for a type.
