摘要： A system and method relates to detecting a hardware event, determining a first virtual memory address associated with the hardware event, wherein the first virtual memory address is associated with a first processing thread, identifying, using the first virtual memory address, an entry of a logical address table, the entry comprising a file descriptor and a file offset associated with a file, identifying a memory address table associated with the file descriptor, translating, using the memory address table, the file offset into a second virtual memory address associated with a second processing thread, and transmitting, to the second processing thread, a notification comprising the second virtual memory address.
