Bound rp2 uart read_blocking and avoid re-interning parity atoms#2362
Merged
Conversation
Cap read_blocking/2 at UINT16_MAX so a large count can no longer over-reserve a binary or park the scheduler core with no timeout. Also replace the per-call globalcontext_make_atom parity chain with a static select table. Signed-off-by: Paul Guyot <pguyot@kallisys.net>
