Trait Implementations

impl SyscallDriver for Eui64

fn command( &self, command_num: usize, _: usize, _: usize, _: ProcessId, ) -> CommandReturn

Control the Eui64.

command_num

• 0: Driver existence check.
• 1: Obtain EUI64 - providing the value within a u64 returncode.

fn allocate_grant(&self, _: ProcessId) -> Result<(), Error>

Request to allocate a capsule’s grant for a specific process.

fn allow_userspace_readable( &self, app: ProcessId, which: usize, slice: ReadWriteProcessBuffer, ) -> Result<ReadWriteProcessBuffer, (ReadWriteProcessBuffer, ErrorCode)>

System call for a process to pass a buffer (a UserspaceReadableProcessBuffer) to the kernel that the kernel can either read or write. The kernel calls this method only after it checks that the entire buffer is within memory the process can both read and write.
