| Subject | [PATCH 0/3] perf tests: Add arch tests |
| Message-ID | <q5r0C-Ua-3@gated-at.bofh.it> |
From: Matt Fleming <matt.fleming@intel.com>
To encourage developers to contribute arch-specific tests without
feeling guilty about messing up the generic perf tests, this patch
series introduces "arch tests" and then adds a test for the Intel CQM
perf code which was used to trigger a WARN_ON_ONCE(), fixed in commit
2c534c0da0a6 ("perf/x86/intel/cqm: Return cached counter value from
IRQ context").
The concept of additional lists of tests, like the arch tests, can be
taken further in the future, for instance Arnaldo has expressed
interest in adding tests that require root permissions, etc.
The patch series is based on tip/perf/core.
The original patch that inspired this series can be found here,
https://lkml.kernel.org/r/1437561539-27939-1-git-send-email-matt@codeblueprint.co.uk

please base this over Arnaldo's perf/core

Yeah, that is better, sometimes, like now, the difference from
tip/perf/core to acme/perf/core can grow as big as 50, 60 patches :-)
BTW I applied the first patch, with Jiri's ack, its in my perf/core
branch now.
