Revision 74545f63890e38520eb4d1dbedcadaa9c0dbc824 authored by David Carrillo-Cisneros on 23 December 2016, 01:17:40 UTC, committed by Ingo Molnar on 05 January 2017, 08:13:55 UTC
The conversion of Intel PMU drivers into modules did not include reference counting. The machine will crash when attempting to access deleted code if an event from a module PMU is started and the module removed before the event is destroyed. i.e. this crashes the machine: $ insmod intel-rapl-perf.ko $ perf stat -e power/energy-cores/ -C 0 & $ rmmod intel-rapl-perf.ko Set THIS_MODULE to pmu->module in Intel module PMUs so that generic code can handle reference counting and deny rmmod while an event still exists.
