So this is great stuff. I worked a bit on isolating the install stuff to a makefile include file. This allows simplifying some of the sub-level Makefiles a bit, and allowing control of some of the install and run logic in less places. This is still a work in progress, but before I got too far along, I wanted to post it for people to provide feedback. A couple of problems cropped up that are worth discussing, IMHO. 1) I think it should be a requirement that each test has a single "main" program to execute to run the tests. If multiple tests are supported or more flexibility is desired for additional arguments, or that sort of thing, then that's fine, but the automated script builder should be able to run just a single program or script to have things work. This also makes things more consistent. In the case of the firmware test, I created a single fw_both.sh script to do this, instead of having two separate blocks in the kselftest.sh script. 2) I've added a CROSS_INSTALL variable, which can call an arbitrary program to place files on the target system (rather than just calling 'install'). In my case, I'd use my own 'ttc cp' command, which I can extend as necessary to put things on a remote machine. This works for a single directory, but things get dicier with sub-directory trees full of files (like the ftrace test uses.) If additional items need to be installed to the target, then maybe a setup program should be used, rather than just copying files. 3) Some of the scripts were using /bin/bash to execute them, rather than rely on the interpreter line in the script itself (and having the script have executable privileges). Is there a reason for this? I modified a few scripts to be executable, and got rid of the explicit execution with /bin/bash. The following is just a start... Let me know if this direction looks OK, and I'll finish this up. The main item to look at is kselftest.include file. Note that these patches are based on Shuah's series - but if you want to use these ideas I can rebase them onto mainline, and break them out per test sub-level like Shuah did. Let me know what you think. >From 14164fd3117c97799a050f8cf791dedc93aa5e82 Mon Sep 17 00:00:00 2001 From: Tim Bird <tim.bird@xxxxxxxxxxxxxx> Date: Wed, 31 Dec 2014 18:04:08 -0800 Subject: [PATCH] Switch to using an include file for common kselftest_install actions --- tools/testing/selftests/cpu-hotplug/Makefile | 15 +++------- .../selftests/cpu-hotplug/cpu-on-off-test.sh | 0 tools/testing/selftests/efivarfs/Makefile | 21 ++++---------- tools/testing/selftests/efivarfs/efivarfs.sh | 0 tools/testing/selftests/firmware/Makefile | 32 ++++------------------ tools/testing/selftests/firmware/fw_both.sh | 13 +++++++++ tools/testing/selftests/kselftest.include | 26 ++++++++++++++++++ tools/testing/selftests/size/Makefile | 19 +++---------- 9 files changed, 60 insertions(+), 69 deletions(-) mode change 100644 => 100755 tools/testing/selftests/cpu-hotplug/cpu-on-off-test.sh mode change 100644 => 100755 tools/testing/selftests/efivarfs/efivarfs.sh create mode 100755 tools/testing/selftests/firmware/fw_both.sh create mode 100644 tools/testing/selftests/kselftest.include diff --git a/tools/testing/selftests/cpu-hotplug/Makefile b/tools/testing/selftests/cpu-hotplug/Makefile index c9e15ee..d2e540d 100644 --- a/tools/testing/selftests/cpu-hotplug/Makefile +++ b/tools/testing/selftests/cpu-hotplug/Makefile @@ -1,18 +1,11 @@ -TEST_STR=/bin/bash ./cpu-on-off-test.sh || echo cpu-hotplug selftests: [FAIL] +TEST_TITLE = cpu-hotplug +TEST_MAIN_PROG = cpu-on-off-test.sh all: -install: -ifdef INSTALL_KSFT_PATH - install ./cpu-on-off-test.sh $(INSTALL_KSFT_PATH)/cpu-on-off-test.sh - @echo "$(TEST_STR)" >> $(KSELFTEST) -else - @echo Run make kselftest_install in top level source directory -endif - -run_tests: - @$(TEST_STR) +include ../kselftest.include +# use -a to get all tests run_full_test: @/bin/bash ./cpu-on-off-test.sh -a || echo "cpu-hotplug selftests: [FAIL]" diff --git a/tools/testing/selftests/cpu-hotplug/cpu-on-off-test.sh b/tools/testing/selftests/cpu-hotplug/cpu-on-off-test.sh old mode 100644 new mode 100755 diff --git a/tools/testing/selftests/efivarfs/Makefile b/tools/testing/selftests/efivarfs/Makefile index aaf404b..8d48e9c 100644 --- a/tools/testing/selftests/efivarfs/Makefile +++ b/tools/testing/selftests/efivarfs/Makefile @@ -1,24 +1,15 @@ -CC = $(CROSS_COMPILE)gcc -CFLAGS = -Wall +TEST_TITLE = efivarfs +TEST_MAIN_PROG = efivarfs.sh -test_objs = open-unlink create-read +CFLAGS = -Wall -TEST_STR = /bin/bash ./efivarfs.sh || echo efivarfs selftests: [FAIL] +TEST_PROGS = open-unlink create-read all: gcc open-unlink.c -o open-unlink gcc create-read.c -o create-read -install: -ifdef INSTALL_KSFT_PATH - install ./efivarfs.sh $(test_objs) $(INSTALL_KSFT_PATH) - @echo "$(TEST_STR)" >> $(KSELFTEST) -else - @echo Run make kselftest_install in top level source directory -endif - -run_tests: all - @$(TEST_STR) +include ../kselftest.include clean: - rm -f $(test_objs) + rm -f $(TEST_PROGS) diff --git a/tools/testing/selftests/efivarfs/efivarfs.sh b/tools/testing/selftests/efivarfs/efivarfs.sh old mode 100644 new mode 100755 diff --git a/tools/testing/selftests/firmware/Makefile b/tools/testing/selftests/firmware/Makefile index 7ac1cf3..b576308 100644 --- a/tools/testing/selftests/firmware/Makefile +++ b/tools/testing/selftests/firmware/Makefile @@ -1,36 +1,14 @@ # Makefile for firmware loading selftests +TEST_MAIN_PROG = fw_both.sh +TEST_TITLE = firmware +TEST_FILES = ./fw_filesystem.sh ./fw_userhelper.sh # No binaries, but make sure arg-less "make" doesn't trigger "run_tests" - -__fw_filesystem: -fw_filesystem = if /bin/sh ./fw_filesystem.sh ;
