samples: guard sub-directories with CONFIG options Do not descend to sub-directories when unneeded. I used subdir-$(CONFIG_...) for hidraw, seccomp, and vfs because they only contain host programs. While we are here, let's add SPDX License tag, and sort the directories alphabetically. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

kbuild: add CONFIG_HEADERS_INSTALL and loosen the dependency of samples Commit 5318321d367c ("samples: disable CONFIG_SAMPLES for UML") used a big hammer to fix the build errors under the samples/ directory. Only some samples actually include uapi headers from usr/include. Introduce CONFIG_HEADERS_INSTALL since 'depends on HEADERS_INSTALL' is clearer than 'depends on !UML'. If this option is enabled, uapi headers are installed before starting directory descending. I added 'depends on HEADERS_INSTALL' to per-sample CONFIG options. This allows UML to compile some samples. $ make ARCH=um allmodconfig samples/ [ snip ] CC [M] samples/configfs/configfs_sample.o CC [M] samples/kfifo/bytestream-example.o CC [M] samples/kfifo/dma-example.o CC [M] samples/kfifo/inttype-example.o CC [M] samples/kfifo/record-example.o CC [M] samples/kobject/kobject-example.o CC [M] samples/kobject/kset-example.o CC [M] samples/trace_events/trace-events-sample.o CC [M] samples/trace_printk/trace-printk.o AR samples/vfio-mdev/built-in.a AR samples/built-in.a Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

tracing: Sample module to demonstrate kernel access to Ftrace instances. This is a sample module to demonstrate the use of the newly introduced and exported APIs to access Ftrace instances from within the kernel. Newly introduced APIs used here - 1. Create/Lookup a trace array with the given name. struct trace_array *trace_array_get_by_name(const char *name) 2. Destroy/Remove a trace array. int trace_array_destroy(struct trace_array *tr) 4. Enable/Disable trace events: int trace_array_set_clr_event(struct trace_array *tr, const char *system, const char *event, bool enable); Exported APIs - 1. trace_printk equivalent for instances. int trace_array_printk(struct trace_array *tr, unsigned long ip, const char *fmt, ...); 2. Helper function. void trace_printk_init_buffers(void); 3. To decrement the reference counter. void trace_array_put(struct trace_array *tr) Sample output(contents of /sys/kernel/tracing/instances/sample-instance) NOTE: Tracing disabled after ~5 sec) _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID CPU# |||| TIMESTAMP FUNCTION | | | |||| | | sample-instance-1452 [002] .... 49.430948: simple_thread: trace_array_printk: count=0 sample-instance-1452 [002] .... 49.430951: sample_event: count value=0 at jiffies=4294716608 sample-instance-1452 [002] .... 50.454847: simple_thread: trace_array_printk: count=1 sample-instance-1452 [002] .... 50.454849: sample_event: count value=1 at jiffies=4294717632 sample-instance-1452 [002] .... 51.478748: simple_thread: trace_array_printk: count=2 sample-instance-1452 [002] .... 51.478750: sample_event: count value=2 at jiffies=4294718656 sample-instance-1452 [002] .... 52.502652: simple_thread: trace_array_printk: count=3 sample-instance-1452 [002] .... 52.502655: sample_event: count value=3 at jiffies=4294719680 sample-instance-1452 [002] .... 53.526533: simple_thread: trace_array_printk: count=4 sample-instance-1452 [002] .... 53.526535: sample_event: count value=4 at jiffies=4294720704 sample-instance-1452 [002] .... 54.550438: simple_thread: trace_array_printk: count=5 sample-instance-1452 [002] .... 55.574336: simple_thread: trace_array_printk: count=6 Link: http://lkml.kernel.org/r/1574276919-11119-3-git-send-email-divya.indi@oracle.com Reviewed-by: Aruna Ramakrishna <aruna.ramakrishna@oracle.com> Signed-off-by: Divya Indi <divya.indi@oracle.com> [ Moved to samples/ftrace ] Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
