  • dcf30fc0c   clocksource/drivers: Replace HTTP links with HTTPS ones ... Browse Code »

    Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

  • 46b30515f   clocksource/drivers/timer-ti-32k: Add support for initializing directly ... Browse Code »

    Let's allow probing the 32k counter directly based on devicetree data to
    prepare for dropping the related legacy platform code. Let's only do this
    if the parent node is compatible with ti-sysc to make sure we have the
    related devicetree data available.

    Let's also show the 32k counter information before registering the
    clocksource, now we see it after the clocksource information which is a
    bit confusing.

  • c77aee71b   clocksource: ti-32k: Remove CLOCK_SOURCE_SUSPEND_NONSTOP flag ... Browse Code »

    Since commit 39232ed5a179 ("time: Introduce one suspend clocksource to
    compensate the suspend time") suspend/resume fails on AM437x platforms as
    the clocksource actually stops in suspend.

    Hence remove the CLOCK_SOURCE_SUSPEND_NONSTOP flag.

  • 172733959   clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE ... Browse Code »

    The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the
    clocksource at early stage. However, this macro is also used to initialize
    the clockevent if any, or the clockevent only.

    It was originally suggested to declare another macro to initialize a
    clockevent, so in order to separate the two entities even they belong to the
    same IP. This was not accepted because of the impact on the DT where splitting
    a clocksource/clockevent definition does not make sense as it is a Linux
    concept not a hardware description.

    On the other side, the clocksource has not interrupt declared while the
    clockevent has, so it is easy from the driver to know if the description is
    for a clockevent or a clocksource, IOW it could be implemented at the driver
    level.

    So instead of dealing with a named clocksource macro, let's use a more generic
    one: TIMER_OF_DECLARE.

    The patch has not functional changes.

  • 3aa601492   clocksource/drivers/ti-32k: Prevent ftrace recursion ... Browse Code »

    Currently ti-32k can be used as a scheduler clock. We properly marked
    omap_32k_read_sched_clock() as notrace but we then call another
    function ti_32k_read_cycles() that _wasn't_ notrace.

    Having a traceable function in the sched_clock() path leads to a
    recursion within ftrace and a kernel crash.

    Fix this by adding notrace attribute to the ti_32k_read_cycles()
    function.

  • 177cf6e52   clocksources: Switch back to the clksrc table ... Browse Code »

    All the clocksource drivers's init function are now converted to return
    an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
    clksrc-of table.

    Let's convert back the names:
    - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
    - clksrc-of-ret => clksrc-of

  • 0a8e7d49d   clocksource/drivers/ti-32k: Convert init function to return error ... Browse Code »

    The init functions do not return any error. They behave as the following:

    - panic, thus leading to a kernel crash while another timer may work and
    make the system boot up correctly

    or

    - print an error and let the caller unaware if the state of the system

    Change that by converting the init functions to return an error conforming
    to the CLOCKSOURCE_OF_RET prototype.

    Proper error handling (rollback, errno value) will be changed later case
    by case, thus this change just return back an error or success in the init
    function.
