Move the x86 arch objects building under build framework to be included in the libperf build object. Adding also arch/$(ARCH)/Build files for the rest of the archs. The reason for this is that in arch/Build we now do: +libperf-y += $(ARCH)/ which would make the build to fail on other architectures, because the build framework requires 'Build' file in nested directories and this patch adds it only for x86.

Jiri Olsa authored
We don't use any built-in rules, so we can disable make's checks for that and build faster. Signed-off-by:

Add support to make directory any time we build objects out of the tree (O=/tmp/krava) and the output directory does not exist. Signed-off-by:

Jiri Olsa authored
Adding support to include detected configuration makefile into the build process. This will allow the Build objects to be configurable based on the config data, like: perf-$(CONFIG_KRAVA) += krava.o The configuration is stored in '.config-detected' file, which is generated for each compilation.

Adding new build framework into 'tools/build' to be used by tools. There's no change for actual building at this point, it comes in the next patches. The idea and more details are explained in the 'tools/build/Documentation/Build.txt' file. I adopted everything from the kernel build system, with some changes to allow for multiple binaries build definitions. While the kernel's build output is single image (forget modules) we need to be able to build several binaries/libraries. The basic idea is that sser provides 'Build' files with objects definitions like: perf-y += a.o perf-y += b.o libperf-y += c.o libperf-y += d.o and the build framework outputs files: perf-in.o # a.o, b.o compiled in libperf-in.o # c.o, d.o compiled in Signed-off-by:

The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE must be defined before pthread.h is included in order to get the proper function declaration. Define this in the Makefile. Without this defined, the feature check fails on a Fedora system with gcc5 and then the perf build later fails with conflicting prototypes for the function. Signed-off-by:

Consolidate .build-id cache path generating routines to build_id__filename() function. Other functions must use it to get the buildid cache path (link path) from build-id. This can reduce the risk of partial-update. Signed-off-by:

Functions related to buildid-cache subcommand use debugdir parameters for passing buildid cache directory path. However all callers just pass buildid_dir global variable. Moreover, other functions which refer buildid cache use buildid_dir directly. This removes unneeded debugdir parameters from those functions and use buildid_dir if needed. Signed-off-by:

The token STT_GNU_IFUNC is not available with glibc 2.9 and older. Define this token if it is not already defined. This patch fixes this build errors with older versions of glibc.

As tracefs may be mounted instead of debugfs to get to the event directories, have perf know about tracefs, and use that file system over debugfs if it is present. Signed-off-by:

Add tracefs_configured() to return true if tracefs is configured in the kernel (succeeds to find tracefs), and debugfs_configured() if debugfs is configured in the kernel (succeeds to find debugfs). Signed-off-by:

Instead of hard coding "/sys/kernel/debug" everywhere, create a macro to hold where the default path exists. Signed-off-by:

Steven Rostedt (Red Hat) authored
Since tracefs will now hold the event directory for perf, and even though by default, debugfs still mounts tracefs on the debugfs/tracing directory, the system admin may now choose to not mount debugfs and instead just mount tracefs instead. Having tracefs helper functions will facilitate having perf look for tracefs first, and then try debugfs as a fallback. Signed-off-by:

Steven Rostedt (Red Hat) authored
In preparation for adding tracefs for perf to use, create a findfs helper utility that find_debugfs uses instead of hard coding the search in the code. This will allow for a find_tracefs to be used as well. Signed-off-by:
