Error Kind Types

TODO: describe error kind types

Critical Errors

The following errors may be escalated to panics or undefined behaviors:

  • Kernel integrity errors (some cases of E_SYS in the TOPPERS kernels).

  • Memory access permission errors (E_MACV) caused by pointers that are supposed to be accessible by the current thread (e.g., pointers referring to local variables).

  • E_PAR caused by invalid timeout values.
