Subject: [PATCH 02/36] perf test: Disable test cases 19 and 20 on s390x
Date: Wed, 6 Dec 2017 11:40:41 -0300 [thread overview]
Message-ID: <20171206144115.15097-3-acme@kernel.org> (raw)
In-Reply-To: <20171206144115.15097-1-acme@kernel.org>
From: Thomas Richter <tmricht@linux.vnet.ibm.com>
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.
