Subject: [RFC 0/2] report perf sampling failing due to PMU lacking overflow intr support
Date: Mon, 9 May 2016 15:07:38 +0530 [thread overview]
Message-ID: <1462786660-2900-1-git-send-email-vgupta@synopsys.com> (raw)
Hi,
A couple of minor patches to print better PMU lacking overflow intr support
such as in ARC700 cores.
This is an ABI change so might be controversial hence RFC.
Despite triviality, I've seperated the change into 2 pacthes - for different maintainers
and also kept userspace change first to keep it bisectable.
Comments welcome !
Thx,
-Vineet
