Structs

HiFive1 🔒

A structure representing this platform that holds references to all capsules for this platform. We’ve included an alarm and console.

Constants

FAULT_RESPONSE 🔒

NUM_PROCS

Statics

CHIP 🔒

PROCESSES 🔒

PROCESS_PRINTER 🔒

STACK_MEMORY

Dummy buffer that causes the linker to reserve enough space for the stack.

Functions

load_processes_not_inlined 🔒

For the HiFive1, if load_process is inlined, it leads to really large stack utilization in main. By wrapping it in a non-inlined function, this reduces the stack utilization once processes are running.

main^⚠

Main function called after RAM initialized.

start 🔒 ^⚠

This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.
