[PATCH v8 0/8] clk: Add kunit tests for fixed rate and parent data

by Stephen Boyd

This patch series adds unit tests for the clk fixed rate basic type and the clk registration functions that use struct clk_parent_data. To get there, we add support for loading device tree overlays onto the live DTB along with probing platform drivers to bind to device nodes in the overlays. With this series, we're able to exercise some of the code in the common clk framework that uses devicetree lookups to find parents and the fixed rate clk code that scans device tree directly and creates clks. Please review. I Cced everyone to all the patches so they get the full context. I'm hoping I can take the whole pile through the clk tree as they all build upon each other. Or the DT part can be merged through the DT tree to reduce the dependencies. Changes from v7: https://lore.kernel.org/r/20240710201246.1802189-1-sboyd@kernel.org * Support modular builds properly by compiling overlay with tests into one .ko * Fold in thinko fix from Geert to DT overlay application patch * Export device_is_bound() to fix module build * Add more module license and description Changes from v6: https://lore.kernel.org/r/20240706045454.215701-1-sboyd@kernel.org * Fix kasan error in platform test by fixing the condition to check for correct free callback * Add module descriptions to new modules Changes from v5: https://lore.kernel.org/r/20240603223811.3815762-1-sboyd@kernel.org * Pick up reviewed-by tags * Drop test vendor prefix bindings as dtschema allows anything now * Use of_node_put_kunit() more to plug some reference leaks * Select DTC config to avoid compile fails because of missing dtc * Don't skip for OF_OVERLAY in overlay tests because they depend on it Changes from v4: https://lore.kernel.org/r/20240422232404.213174-1-sboyd@kernel.org * Picked up reviewed-by tags * Check for non-NULL device pointers before calling put_device() * Fix CFI issues with kunit actions * Introduce platform_device_prepare_wait_for_probe() helper to wait for a platform device to probe * Move platform code to lib/kunit and rename functions to have kunit prefix * Fix issue with platform wrappers messing up reference counting because they used kunit actions * New patch to populate overlay devices on root node for powerpc * Make fixed-rate binding generic single clk consumer binding Changes from v3: https://lore.kernel.org/r/20230327222159.3509818-1-sboyd@kernel.org * No longer depend on Frank's series[1] because it was merged upstream[2] * Use kunit_add_action_or_reset() to shorten code * Skip tests properly when CONFIG_OF_OVERLAY isn't set Changes from v2: https://lore.kernel.org/r/20230315183729.2376178-1-sboyd@kernel.org * Overlays don't depend on __symbols__ node

[PATCH v3] selftests: sched_ext: Add sched_ext as proper selftest target

by Björn Töpel

From: Björn Töpel <bjorn(a)rivosinc.com> The sched_ext selftests is missing proper cross-compilation support, a proper target entry, and out-of-tree build support. When building the kselftest suite, e.g.: make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \ TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \ -C tools/testing/selftests install or: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests install The expectation is that the sched_ext is included, cross-built, the correct toolchain is picked up, and placed into /output/foo. In contrast to the BPF selftests, the sched_ext suite does not use bpftool at test run-time, so it is sufficient to build bpftool for the build host only. Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext selftest. Also, remove some variables that were unused by the Makefile. Signed-off-by: Björn Töpel <bjorn(a)rivosinc.com> --- v3: * Always build a build host version of bpftool (Mark) * Make sure LLVM style "ARCH only" cross-build works (Mark) v2: * Removed the duplicated LLVM prefix parsing (David) * Made sure make clean didn't do a complete mess (David) * Added sched_ext to default skip (Shuah) --- tools/testing/selftests/Makefile | 9 +-- tools/testing/selftests/sched_ext/Makefile | 73 ++++++++++------------ 2 files changed, 38 insertions(+), 44 deletions(-) diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index b38199965f99..363d031a16f7 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -88,6 +88,7 @@ TARGETS += rlimits TARGETS += rseq TARGETS += rtc TARGETS += rust +TARGETS += sched_ext TARGETS += seccomp TARGETS += sgx TARGETS += sigaltstack @@ -129,10 +130,10 @@ ifeq ($(filter net/lib,$(TARGETS)),) endif endif -# User can optionally provide a TARGETS skiplist.

[PATCH v5 0/4] selftests: kvm: s390: Add ucontrol memory selftests

by Christoph Schlameuss

This patch series adds a some not yet picked selftests to the kvm s390x selftest suite. The additional test cases are covering: * Assert KVM_EXIT_S390_UCONTROL exit on not mapped memory access * Assert functionality of storage keys in ucontrol VM * Assert that memory region operations are rejected for ucontrol VMs Running the test cases requires sys_admin capabilities to start the ucontrol VM. This can be achieved by running as root or with a command like: sudo setpriv --reuid nobody --inh-caps -all,+sys_admin \ --ambient-caps -all,+sys_admin --bounding-set -all,+sys_admin \ ./ucontrol_test --- The patches in this series have been part of the previous patch series. The test cases added here do depend on the fixture added in the earlier patches. From v5 PATCH 7-9 the segment and page table generation has been removed and DAT has been disabled. Since DAT is not necessary to validate the KVM code. https://lore.kernel.org/kvm/20240807154512.316936-1-schlameuss@linux.ibm.co… v5: - rebased to current upstream master - corrected assertion on 0x00 to 0 - reworded fixup commit so that it can be merged on top of current upstream v4: - fix whitespaces in pointer function arguments (thanks Claudio) - fix whitespaces in comments (thanks Janosch) v3: - fix skey assertion (thanks Claudio) - introduce a wrapper around UCAS map and unmap ioctls to improve readability (Claudio) - add an displacement to accessed memory to assert translation intercepts actually point to segments to the uc_map_unmap test - add an misaligned failing mapping try to the uc_map_unmap test v2: - Reenable KSS intercept and handle it within skey test. - Modify the checked register between storing (sske) and reading (iske) it within the test program to make sure the. - Add an additional state assertion in the end of uc_skey - Fix some typos and white spaces. v1: - Remove segment and page table generation and disable DAT. This is not necessary to validate the KVM code.

[PATCH] selftest: hid: add the missing tests directory

by Yun Lu

Commit 160c826b4dd0 ("selftest: hid: add missing run-hid-tools-tests.sh") has added the run-hid-tools-tests.sh script for it to be installed, but I forgot to add the tests directory together. In fact, the run-hid-tools-tests.sh script uses the scripts in the tests directory to run tests. The tests directory also needs to be added to be installed.
