Subject: [PATCH] perf test: disable test cases 19 and 20 on s390x
Date: Thu, 23 Nov 2017 08:46:23 +0100 [thread overview]
Message-ID: <20171123074623.20817-1-tmricht@linux.vnet.ibm.com> (raw)
The s390x CPU sampling and measurement facilities do not
support perf events of type PERF_TYPE_BREAKPOINT. The
test cases are executed and fail with -ENOENT due to
missing hardware support.
Disable the execution of both test cases based on a
platform check. This is the same approach as done for
PowerPC.
