From: Patrick Tasse Date: Thu, 5 Nov 2015 17:50:26 +0000 (-0500) Subject: tmf: Add Lost Events marker event source and factory X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c53cebea8f576ee49bc07de8c4d7fa90ef408028;p=deliverable%2Ftracecompass.git tmf: Add Lost Events marker event source and factory A marker event source factory for Lost Events is enabled for all traces. The marker event source can reuse a previously returned marker list if the requested parameters are identical to the previous request. The event types statistics state system is updated to add a new attribute which is used to compute the time ranges that are covered by at least one lost event time range.
