Run "make quicktest=1 run_tests" or

"make quicktest=1 kselftest" from top level Makefile

User can optionally provide a TARGETS skiplist. By default we skip

BPF since it has cutting edge build time dependencies which require

more effort to install.

SKIP_TARGETS ?= bpf ifneq ($(SKIP_TARGETS),) TMP := $(filter-out $(SKIP_TARGETS), $(TARGETS)) override TARGETS := $(TMP) endif

User can set FORCE_TARGETS to 1 to require all targets to be successfully

built; make will fail if any of the targets cannot be built. If

FORCE_TARGETS is not set (the default), make will succeed if at least one

of the targets gets built.

FORCE_TARGETS ?=

Clear LDFLAGS and MAKEFLAGS when implicit rules are missing. This provides

implicit rules to sub-test Makefiles which avoids build failures in test

Makefile that don't have explicit build rules.

ifeq (,$(LINK.c)) override LDFLAGS = override MAKEFLAGS = endif

Append kselftest to KBUILD_OUTPUT and O to avoid cluttering

KBUILD_OUTPUT with selftest objects and headers installed

by selftests Makefile or lib.mk.

ifdef building_out_of_srctree override LDFLAGS = endif

top_srcdir ?= ../../..

ifeq ("$(origin O)", "command line") KBUILD_OUTPUT := $(O) endif

ifneq ($(KBUILD_OUTPUT),)

Make's built-in functions such as $(abspath ...), $(realpath ...) cannot

expand a shell special character '~'. We use a somewhat tedious way here.

abs_objtree := $(shell cd $(top_srcdir) && mkdir -p $(KBUILD_OUTPUT) && cd $(KBUILD_OUTPUT) && pwd) $(if $(abs_objtree),,
$(error failed to create output directory "$(KBUILD_OUTPUT)"))

$(realpath ...) resolves symlinks

abs_objtree := $(realpath $(abs_objtree)) BUILD := $(abs_objtree)/kselftest KHDR_INCLUDES := -isystem ${abs_objtree}/usr/include else BUILD := $(CURDIR) abs_srctree := $(shell cd $(top_srcdir) && pwd) KHDR_INCLUDES := -isystem ${abs_srctree}/usr/include DEFAULT_INSTALL_HDR_PATH := 1 endif

Prepare for headers install

set default goal to all, so make without a target runs all, even when

all isn't the first target in the file.

.DEFAULT_GOAL := all

Use $BUILD as the default install root. $BUILD points to the

right output location for the following cases:

1. output_dir=kernel_src

2. a separate output directory is specified using O= KBUILD_OUTPUT

3. a separate output directory is specified using KBUILD_OUTPUT

Avoid conflict with INSTALL_PATH set by the main Makefile

KSFT_INSTALL_PATH ?= $(BUILD)/kselftest_install KSFT_INSTALL_PATH := $(abspath $(KSFT_INSTALL_PATH))

Avoid changing the rest of the logic here and lib.mk.
