tools build: Move tabs to spaces where suitable We've been hit several times by a Makefile bug where line indented by tab was falsely considered as target command. We prevent this by always using space indentation for everything except for the target commands.

tools/perf/build: Add feature check core code Start the split-out of the feature check code by adding a list of features to be tested, and rules to process that list by building its matching feature-check file in config/feature-checks/test-<feature>.c. Add 'hello' as the initial feature. This structure will allow us to build split-out feature checks in parallel and thus speed up feature detection dramatically. No change in functionality: no feature check is used by the build rules yet.

perf: tools: Fix cross building Currently the feature-checks Makefile does not inherit $(CC), and calls cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the native toolchain rather than the cross toolchain, and can identify features as available when they are not. This can break the build. Additionally the native pkg-config is always called as opposed to $(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed to the cross compiler. This patch passes CROSS_COMPILE down to the feature-checks Makefile, and forces its use. Additionally pkg-config is replaced with $(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable. This patch has been build tested on x86_64 and arm.

tools build: Add feature detection for LLVM Check if basic LLVM compiling environment is ready. Use llvm-config to detect include and library directories. Avoid using 'llvm-config --cxxflags' because its result contain some unwanted flags like --sysroot (if LLVM is built by yocto). Use '?=' to set LLVM_CONFIG, so explicitly passing LLVM_CONFIG to make would override it. Use 'llvm-config --libs BPF' to check if BPF backend is compiled in. Since now BPF bytecode is the only required backend, no need to waste time linking llvm and clang if BPF backend is missing. This also introduce an implicit requirement that LLVM should be new enough. Old LLVM doesn't support BPF backend.

tools/perf/build: Fix feature-libunwind-debug-frame handling Set feature-libunwind-debug-frame. We don't want it in CORE_FEATURE_TESTS because it's not the generic case, but we need to set it in the !feature-libunwind case. Also, because x86 distributions typically don't have dwarf_find_debug_frame() unwinding method: test-libunwind-debug-frame.c:(.text+0x31): undefined reference to `_Ux86_64_dwarf_find_debug_frame' Restrict this new API to ARM for the time being.

perf: tools: Fix cross building Currently the feature-checks Makefile does not inherit $(CC), and calls cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the native toolchain rather than the cross toolchain, and can identify features as available when they are not. This can break the build. Additionally the native pkg-config is always called as opposed to $(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed to the cross compiler. This patch passes CROSS_COMPILE down to the feature-checks Makefile, and forces its use. Additionally pkg-config is replaced with $(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable.

$(OUTPUT)test-bpf.bin:
bpf tools: Introduce 'bpf' library and add bpf feature check This is the first patch of libbpf. The goal of libbpf is to create a standard way for accessing eBPF object files. This patch creates 'Makefile' and 'Build' for it, allows 'make' to build libbpf.a and libbpf.so, 'make install' to put them into proper directories. Most part of Makefile is borrowed from traceevent. Before building, it checks the existence of libelf in Makefile, and deny to build if not found. Instead of throwing an error if libelf not found, the error raises in a phony target "elfdep". This design is to ensure 'make clean' still workable even if libelf is not found. Because libbpf requires 'kern_version' field set for 'union bpf_attr' (bpfdep" is used for that dependency), Kernel BPF API is also checked by intruducing a new feature check 'bpf' into tools/build/feature, which checks the existence and version of linux/bpf.h. When building libbpf, it searches that file from include/uapi/linux in kernel source tree (controlled by FEATURE_CHECK_CFLAGS-bpf). Since it searches kernel source tree it reside, installing of newest kernel headers is not required, except we are trying to port these files to an old kernel. To avoid checking that file when perf building, the newly introduced 'bpf' feature check doesn't added into FEATURE_TESTS and FEATURE_DISPLAY by default in tools/build/Makefile.feature, but added into libbpf's specific.

tools build: Add feature detection for LLVM Check if basic LLVM compiling environment is ready. Use llvm-config to detect include and library directories. Avoid using 'llvm-config --cxxflags' because its result contain some unwanted flags like --sysroot (if LLVM is built by yocto). Use '?=' to set LLVM_CONFIG, so explicitly passing LLVM_CONFIG to make would override it. Use 'llvm-config --libs BPF' to check if BPF backend is compiled in. Since now BPF bytecode is the only required backend, no need to waste time linking llvm and clang if BPF backend is missing. This also introduce an implicit requirement that LLVM should be new enough. Old LLVM doesn't support BPF backend.
