impl<I: I2CDevice> SyscallDriver for MAX17205Driver<'_, I>

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

Setup and read the MAX17205.

command_num

• 0: Driver existence check.
• 1: Read the current status of the MAX17205.
• 2: Read the current state of charge percent.
• 3: Read the current voltage and current draw.
• 4: Read the raw coulomb count.
• 5: Read the unique 64 bit RomID.

fn allocate_grant(&self, processid: 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.
