Trait kernel::driver::DriverOps

pub trait DriverOps {
    type RegType: Default;

    unsafe fn register(
        reg: *mut Self::RegType,
        name: &'static CStr,
        module: &'static ThisModule
    ) -> Result;
    unsafe fn unregister(reg: *mut Self::RegType);
}

A subsystem (e.g., PCI, Platform, Amba, etc.) that allows drivers to be written for it.

Required Associated Types

type RegType: Default

The type that holds information about the registration. This is typically a struct defined by the C portion of the kernel.

Required Methods

unsafe fn register(
    reg: *mut Self::RegType,
    name: &'static CStr,
    module: &'static ThisModule
) -> Result

Registers a driver.

Safety

reg must point to valid, initialised, and writable memory. It may be modified by this function to hold registration state.

On success, reg must remain pinned and valid until the matching call to DriverOps::unregister.

unsafe fn unregister(reg: *mut Self::RegType)

Unregisters a driver previously registered with DriverOps::register.

Safety

reg must point to valid writable memory, initialised by a previous successful call to DriverOps::register.
