Subject: [PATCH v5 01/11] kselftest: arm64: add skeleton Makefile
Date: Mon, 2 Sep 2019 12:29:22 +0100 [thread overview]
Message-ID: <20190902112932.36129-2-cristian.marussi@arm.com> (raw)
In-Reply-To: <20190902112932.36129-1-cristian.marussi@arm.com>
Add a new arm64-specific empty subsystem amongst TARGETS of KSFT build
framework; keep these new arm64 KSFT testcases separated into distinct
subdirs inside tools/testing/selftests/arm64/ depending on the specific
subsystem targeted.
Add into toplevel arm64 KSFT Makefile a mechanism to guess the effective
location of Kernel headers as installed by KSFT framework.
Merge with
commit 9ce1263033cd ("selftests, arm64: add a selftest for passing
tagged pointers to kernel")
while moving such KSFT tags tests inside their own subdirectory
(arm64/tags).
Signed-off-by: Cristian Marussi <cristian.marussi@arm.com>
---
v4 --> v5
- rebased on arm64/for-next/core
- merged this patch with KSFT arm64 tags patch, while moving the latter
into its own subdir
- moved kernel header includes search mechanism from KSFT arm64
SIGNAL Makefile
- export proper top_srcdir ENV for lib.mk
v3 --> v4
- comment reword
- simplified documentation in README
- dropped README about standalone

+KSelfTest ARM64
+===============
+
+- These tests are arm64 specific and so not built or run but just skipped
+ completely when env-variable ARCH is found to be different than 'arm64'
+ and `uname -m` reports other than 'aarch64'.
+
+- Holding true the above, ARM64 KSFT tests can be run within the KSelfTest
+ framework using standard Linux top-level-makefile targets:
+
+ $ make TARGETS=arm64 kselftest-clean
+ $ make TARGETS=arm64 kselftest
+
+ or
+
+ $ make -C tools/testing/selftests TARGETS=arm64 \
+ INSTALL_PATH=<your-installation-path> install
+
+ Further details on building and running KFST can be found in:
+ Documentation/dev-tools/kselftest.rst
