Multicore memory data recorder for kernel module

A method, comprising:

• monitoring, by a kernel recorder coupled to a processing core, execution of a task;
• determining whether the execution of the task enters or exits a code segment identified as being monitored;
• responsive to determining that the task being executed enters the code segment, setting the kernel recorder to a first mode under which the kernel recorder is to record, in a first record, a plurality of memory addresses accessed by the code segment;
• and
• responsive to determining that the execution of the task exists the code segment, setting the kernel recorder to a second mode under which the kernel recorder is to detect a write operation to a memory address recorded in the first record and record the memory address in a second record.

A system-on-a-chip (SoC) comprising:

• a memory;
• a processing core, coupled to the memory, to execute a task comprising a code segment identified as being monitored;
• and
• a kernel recorder, coupled to the processing core via a core interface, the kernel recorder comprising a first filter circuit to:
• responsive to determining that the task being executed enters the code segment, set the kernel recorder to a first mode under which the kernel recorder is to record, in a first record, a plurality of memory addresses accessed by the code segment;
• and
• responsive to determining that the execution of the task exits the code segment, set the kernel recorder to a second mode under which the kernel recorder is to detect a write operation to a memory address recorded in the first record and record the memory address in a second record.
