Each intel processor trace table of physical addresses (ToPA) entry has an INT bit. If this bit is set, the processor will signal a performance-monitoring interrupt (PMI) when the corresponding trace output region is filled. This patch set will inject a PMI for Intel Processor Trace when ToPA buffer is filled.
