Struct KObjectStore 

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

The owner of all the KObjects in sysfs.

This structure 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>

The root of the sysfs hierarchy.

Implementations

impl KObjectStore

pub fn init<L>(&self, locked: &mut Locked<L>, kernel: &Kernel)

where L: LockEqualOrBefore<FileOpsCore>,

pub fn virtual_bus(&self) -> Bus

The virtual bus kobject where all virtual and pseudo devices are stored.

pub fn virtual_block_class(&self) -> Class

The device class used for virtual block devices.

pub fn virtual_thermal_class(&self) -> Class

The device class used for virtual thermal devices.

pub fn graphics_class(&self) -> Class

The device class used for virtual graphics devices.

pub fn input_class(&self) -> Class

The device class used for virtual input devices.

pub fn mem_class(&self) -> Class

The device class used for virtual mem devices.

pub fn net_class(&self) -> Class

The device class used for virtual net devices.

pub fn misc_class(&self) -> Class

The device class used for virtual misc devices.

pub fn tty_class(&self) -> Class

The device class used for virtual tty devices.

pub fn dma_heap_class(&self) -> Class

The device class used for virtual dma_heap devices.

pub fn starnix_class(&self) -> Class

An 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 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, bus: Bus) -> Class

Get a class by name.

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

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

impl Default for KObjectStore

fn default() -> Self

Returns the “default value” for a type.
