From 315ae2d4c4396fa4f19f5a2be0d73afb9cfa7b31 Mon Sep 17 00:00:00 2001 From: Yan Wang Date: Tue, 16 Jul 2019 15:29:08 -0700 Subject: Add support of trace duration for host python compiler. The basic idea is add timestamp for MmFilemapAddToPageCache. Treat the first receiving MmFilemapAddToPageCache timestamp as the start time. The end time is the sum of start time and duration. Any MmFilemapAddToPageCache after end time is filtered out.
