| |
From: Wudi Wang <wangwudi@hisilicon.com>
INVALL CMD specifies that the ITS must ensure any caching associated with the interrupt collection defined by ICID is consistent with the LPI configuration tables held in memory for all Redistributors. SYNC is required to ensure that INVALL is executed.
Currently, LPI configuration data may be inconsistent with that in the memory within a short period of time after the INVALL command is executed.
