From 2b9032e0ecb57de819bcf40b440e7cbd2d8f3a8c Mon Sep 17 00:00:00 2001 From: Alexander Yarygin Date: Fri, 25 Apr 2014 17:34:05 +0200 Subject: [PATCH] perf tools: Parse tracepoints with '-' in system name Trace events potentially can have a '-' in their trace system name, e.g. kvm on s390 defines kvm-s390:* tracepoints. We could not parse them, because there was no rule for this: $ sudo ./perf top -e "kvm-s390:*" invalid or unsupported event: 'kvm-s390:*' This patch adds an extra rule to event_legacy_tracepoint which handles those cases. Without the patch, perf will not accept such tracepoints in the -e option.
