classmethod
setup_online_mask
(symbol: gdb.Symbol) → None[source]
Translate the cpu_online_mask
bitmap into a list of
online CPU numbers.
Meant to be used as a SymbolCallback.
Parameters: | symbol – The symbol for cpu_online_mask or
__cpu_online_mask , depending on kernel version. |

bitmap into a list of
possible CPU numbers.
Meant to be used as a SymbolCallback.
Parameters: | cpu_mask – The symbol for cpu_possible_mask or
__cpu_possible_mask , depending on kernel version. |
