selftests: complete kselftest include centralization

2025-11-27T22:24:31+00:00

This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

selftests/binderfs: use the Makefile's rules, not Make's implicit rules

2024-05-06T19:57:21+00:00

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...the following error occurs: clang: error: cannot specify -o when generating multiple output files This is because clang, unlike gcc, won't accept invocations of this form: clang file1.c header2.h While trying to fix this, I noticed that: a) selftests/lib.mk already avoids the problem, and b) The binderfs Makefile indavertently bypasses the selftests/lib.mk build system, and quitely uses Make's implicit build rules for .c files instead. The Makefile attempts to set up both a dependency and a source file, neither of which was needed, because lib.mk is able to automatically handle both. This line: binderfs_test: binderfs_test.c ...causes Make's implicit rules to run, which builds binderfs_test without ever looking at lib.mk. Fix this by simply deleting the "binderfs_test:" Makefile target and letting lib.mk handle it instead.

selftests: filesystems: Fix incorrect kernel headers search path

2023-02-13T16:09:44+00:00

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

remove CONFIG_ANDROID

Pull char / misc / other smaller driver subsystem updates from Greg KH: "Here is the large set of char, misc, and other driver subsystem updates for 5.19-rc1. The merge request for this has been delayed as I wanted to get lots of linux-next testing due to some late arrivals of changes for the habannalabs driver. Highlights of this merge are: - habanalabs driver updates for new hardware types and fixes and other updates - IIO driver tree merge which includes loads of new IIO drivers and cleanups and additions - PHY driver tree merge with new drivers and small updates to existing ones - interconnect driver tree merge with fixes and updates - soundwire driver tree merge with some small fixes - coresight driver tree merge with small fixes and updates - mhi bus driver tree merge with lots of updates and new device support - firmware driver updates - fpga driver updates - lkdtm driver updates (with a merge conflict, more on that below) - extcon driver tree merge with small updates - lots of other tiny driver updates and fixes and cleanups, full details in the shortlog.
