The hearer text 'List of pre-defined events (to be used in -e):' is placed in an improper function, which causes an abnormal output, e.g. 'perf list hw' shows no guiding text at all, and 'perf list hw L1-dcache*' shows the guiding text incorrectly in the middle of the output. Example Before this patch: $ perf list hw L1-dcache* branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cache-misses [Hardware event] cache-references [Hardware event] cpu-cycles OR cycles [Hardware event] instructions [Hardware event] stalled-cycles-backend OR idle-cycles-backend [Hardware event] stalled-cycles-frontend OR idle-cycles-frontend [Hardware event] List of pre-defined events (to be used in -e): <-- incorrect position L1-dcache-load-misses [Hardware cache event] L1-dcache-loads [Hardware cache event] L1-dcache-prefetch-misses [Hardware cache event] L1-dcache-prefetches [Hardware cache event] L1-dcache-store-misses [Hardware cache event] L1-dcache-stores [Hardware cache event] After this patch: $ perf list hw L1-dcache* List of pre-defined events (to be used in -e): <-- correct position branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cache-misses [Hardware event] cache-references [Hardware event] cpu-cycles OR cycles [Hardware event] instructions [Hardware event] stalled-cycles-backend OR idle-cycles-backend [Hardware event] stalled-cycles-frontend OR idle-cycles-frontend [Hardware event] L1-dcache-load-misses [Hardware cache event] L1-dcache-loads [Hardware cache event] L1-dcache-prefetch-misses [Hardware cache event] L1-dcache-prefetches [Hardware cache event] L1-dcache-store-misses [Hardware cache event] L1-dcache-stores [Hardware cache event] Signed-off-by:

The function is_power_of_2() also do the check on nr_pages, so the first check performed is unnecessary. On the other hand, the key point is to ensure @nr_pages is a power-of-two number and mostly @nr_pages is a nonzero value, so in the most cases, the function is_power_of_2() will be called.

Fix the 'segmentation fault' bug of 'perf list --list-cmds', which also happens in other cases (e.g. record, report ...). This bug happens when there are no cmds to list at all. Example: Before this patch: $ perf list --list-cmds Segmentation fault $ After this patch: $ perf list --list-cmds $ As shown above, the result prints nothing rather than a segmentation fault. The null result means 'perf list' has no cmds to display at this time. Signed-off-by:

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.

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:
