A non-transitory storage medium including instructions that are executable by one or more processors to perform operations including instrumenting a VM is shown. The VM is used to process an object to determine whether the object is associated with malware. Logic within the VM analyzes memory allocated for a process within the VM for a point of interest (POI), the POI being an address of one of a set predetermined instructions likely to be associated with malware. The VMM detects a memory violation during processing of the object and responsive to detecting the memory violation, injects a transition event at the POI on the page on which the POI is located in memory. Further, responsive to detecting an attempted execution of the transition event, the VMM (i) emulates an instruction located at the POI, and (ii) the logic within the VM performs one or more malware detection routines.

A system chip has many local blocks including processor cores, caches, and memory controllers. Each local block has a local sample-select mux that is controlled by a local selection control register. The mux selects from among hundreds of internal sample nodes in the local block, and can also pass through samples output by an upstream local block. The selected samples from local blocks are sent to a central on-chip logic analyzer that compares the samples to a maskable trigger value. When the trigger value is matched, a trigger state machine advances, and samples are stored into a central capture buffer. A user debugging the chip can later read out the central capture buffer at a slower speed. Thousands of internal nodes from local blocks can be selected for sampling, triggering, and debugging. Local blocks include valid bits in 64-bit-wide samples. Only valid samples are written to the capture buffer.
