1# This file documents the expected order of execution of ESP_SYSTEM_INIT_FN functions.
2#
3# When adding new ESP_SYSTEM_INIT_FN functions or changing init priorities of existing functions,
4# keep this file up to date. This is checked in CI.
5# When adding new functions or changing the priorities, please read the comments and see if
6# they need to be updated to be consistent with the changes you are making.
7#
8# Entries are ordered by the order of execution (i.e. from low priority values to high ones).
9# Each line has the following format:
10#   prio: function_name in path/to/source_file on affinity_expression
11# Where:
12#   prio: priority value (higher value means function is executed later)
13#   affinity_expression: bit map of cores the function is executed on
