  • 184892925   samples: move blackfin gptimers-example from Documentation ... Browse Code »

    Move blackfin gptimers-example to samples and remove it from Documentation
    Makefile. Update samples Kconfig and Makefile to build gptimers-example.

    blackfin is the last CONFIG_BUILD_DOCSRC target in Documentation/Makefile.
    Hence this patch also includes changes to remove CONFIG_BUILD_DOCSRC from
    Makefile and lib/Kconfig.debug and updates VIDEO_PCI_SKELETON dependency
    on BUILD_DOCSRC.

    Documentation/Makefile is not deleted to avoid braking make htmldocs and
    make distclean.

  • f6041c1d8   samples/seccomp: Add standalone config option ... Browse Code »

    Add a separate Kconfig option for SAMPLES_SECCOMP.

    Main reason for this is that, just like other samples, it's forced to
    be a module.

    Without this, since the sample is a target only controlled by
    CONFIG_SECCOMP_FILTER, the samples will be built before include files are
    put in place properly. For example, from an arm64 allmodconfig built with
    "make -sk -j 32" (without specific target), the following happens:

    samples/seccomp/bpf-fancy.c:13:27: fatal error: linux/seccomp.h: No such file or directory
    samples/seccomp/bpf-helper.h:20:50: fatal error: linux/seccomp.h: No such file or directory
    samples/seccomp/dropper.c:20:27: fatal error: linux/seccomp.h: No such file or directory
    samples/seccomp/bpf-direct.c:21:27: fatal error: linux/seccomp.h: No such file or directory

    So, just stick to the same format as other samples.

  • aad108aa9   tracing: Add trace_printk sample code ... Browse Code »

    Add sample code to test trace_printk(). The trace_printk() functions should
    never be used in production code. This makes testing it a bit more
    difficult. Having a sample module that can test use cases of trace_printk()
    can help out.

    Currently it just tests trace_printk() where it will be converted into:

    trace_bputs()
    trace_puts()
    trace_bprintk()

    as well as staying as the normal _trace_printk().

    It also tests its use in interrupt context as that will test the auxilery
    buffers.

  • 14fbff6b4   samples: connector: from Documentation to samples directory ... Browse Code »

    A small bug with the new autoksyms support showed that there are
    two kernel modules in the Documentation directory that qualify
    as samples, while all other samples are in the samples/ directory.

    This patch was originally meant as a workaround for that bug, but
    it has now been solved in a different way. However, I still think
    it makes sense as a cleanup to consolidate all sample code in
    one place.

  • d75f717e1   tracing: Remove tracepoint sample code ... Browse Code »

    The tracepoint sample code was used to teach developers how to
    create their own tracepoints. But now the trace_events have been
    added as a higher level that is used directly by developers today.

    Only the trace_event code should use the tracepoint interface
    directly and no new tracepoints should be added.

    Besides, the example had a race condition with the use of the
    ->d_name.name dentry field, as pointed out by Al Viro.

    Best just to remove the code so it wont be used by other developers.

  • 779b96d20   samples/rpmsg: add an rpmsg driver sample ... Browse Code »

    Add an rpmsg driver sample, which demonstrates how to communicate with
    an AMP-configured remote processor over the rpmsg bus.

    Note how once probed, the driver can immediately start sending messages
    using the rpmsg_send() API, without having to worry about creating endpoints
    or allocating rpmsg addresses: all that work is done by the rpmsg bus,
    and the required information is already embedded in the rpmsg channel
    that the driver is probed with.

    In this sample, the driver simply sends a "Hello World!" message to the remote
    processor repeatedly.

  • d431b2e33   HID: hid-example: fix some build issues ... Browse Code »

    samples/hid-example.o needs some Kconfig and Makefile additions in order
    to build. It should use headers from the build tree, so use
    HEADERS_CHECK to require that those header files be present.

    Change the kconfig symbol from tristate to bool since userspace cannot be
    built as loadable modules.

    However, I don't understand why the userspace header files are not present
    as reported in Andrew's build log, since it builds OK on x86_64 without
    any of these changes.

    Move kprobes examples from Documentation/kprobes.txt to under samples/.
    Patch originally by Randy Dunlap.

    o Updated the patch to apply on 2.6.25-rc3
    o Modified examples code to build on multiple architectures. Currently,
    the kprobe and jprobe examples code works for x86 and powerpc
    o Cleaned up unneeded #includes
    o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break
    on archs that don't have kretprobes
    o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES
    o Included Andrew Morton's cleanup based on x86-git
    o Modified kretprobe_example to act as a arch-agnostic module to
    determine routine execution times:
    Use 'modprobe kretprobe_example func=' to determine
    execution time of func_name in nanoseconds.
