Crate kernel

Core Tock Kernel

The kernel crate implements the core features of Tock as well as shared code that many chips, capsules, and boards use. It also holds the Hardware Interface Layer (HIL) definitions.

Most unsafe code is in this kernel crate.

Modules

callback	Data structure for storing a callback to userspace or kernelspace.
common	Common operations in the Tock OS.
debug	Support for in-kernel debugging.
driver	System call interface for userspace applications.
grant	Data structure to store a list of userspace applications.
hil	Public traits for interfaces between Tock components.
ipc	Inter-process communication mechanism for Tock.
mem	Data structure for passing application memory to the kernel.
memop	Implementation of the MEMOP family of syscalls.
mpu	Interface for configuring the Memory Protection Unit.
platform
process	Support for creating and running userspace applications.
returncode	Standard return type for invoking operations, returning success or an error code.
sched	Tock core scheduler.
support	A bare-metal library supplying functions rustc may lower code to.
syscall	Tock syscall number definitions.
systick	Interface system tick timer.

Macros

debug	In-kernel println() debugging.
debug_gpio	In-kernel gpio debugging, accepts any GPIO HIL method
debug_verbose	In-kernel println() debugging with filename and line numbers.
register_bitfields	Define register types and fields.
register_bitmasks	Helper macro for defining register fields.
static_init	Allocates a global array of static size to initialize data structures.
storage_volume	Allocates space in the kernel image for on-chip non-volatile storage. Storage volumes are placed after the kernel code and before relocated variables (those copied into RAM on boot). They are placed in a section called ".storage".

Traits

Chip	Interface for individual MCUs.
Platform	Interface for individual boards.
SysTick	Interface for the system tick timer.

Functions

main	Main loop.
