Expand description

@brief Spinlock object Owner:

  • Set to 0 if uninitialized
  • Set to portMUX_FREE_VAL when free
  • Set to CORE_ID_REGVAL_PRO or CORE_ID_REGVAL_AP when locked
  • Any other value indicates corruption Count:
  • 0 if unlocked
  • Recursive count if locked

@note Not a true spinlock as single core RISC-V does not have atomic compare and set instruction @note Keep portMUX_INITIALIZER_UNLOCKED in sync with this struct
