Abstract
A processor includes a global register to store a value of an interrupted block count. A processor core, communicably coupled to the global register, may, upon execution of an instruction to flush blocks of a cache that are associated with a security domain: flush the blocks of the cache sequentially according to a flush loop of the cache; and in response to detection of a system interrupt: store a value of a current cache block count to the global register as the interrupted block count; and stop execution of the instruction to pause the flush of the blocks of the cache. After handling of the interrupt, the instruction may be called again to restart the flush of the cache.
