  • a987e6b91   remoteproc: fix trace buffer va initialization ... Browse Code »

    With rproc_alloc_registered_carveouts() introduction, carveouts are
    allocated after resource table parsing.
    rproc_da_to_va() may return NULL at trace resource registering.
    This patch modifies trace debufs registering to provide device address
    (da) instead of va.
    da to va translation is done at each trace buffer access
    through debugfs interface.

  • 92792e48e   remoteproc: avoid stack overflow in debugfs file ... Browse Code »

    Recent gcc versions warn about reading from a negative offset of
    an on-stack array:

    drivers/remoteproc/remoteproc_debugfs.c: In function 'rproc_recovery_write':
    drivers/remoteproc/remoteproc_debugfs.c:167:9: warning: 'buf[4294967295u]' may be used uninitialized in this function [-Wmaybe-uninitialized]

    I don't see anything in sys_write() that prevents us from
    being called with a zero 'count' argument, so we should
    add an extra check in rproc_recovery_write() to prevent the
    access and avoid the warning.

  • 2e37abb89   remoteproc: create a 'recovery' debugfs entry ... Browse Code »

    Add a 'recovery' debugfs entry to dynamically disable/enable recovery
    at runtime. This is useful when one is trying to debug an rproc crash;
    without it, a recovery will immediately take place, making it harder
    to debug the crash.

    Contributions from Subramaniam Chanderashekarapuram.

    Examples:

    - disabling recovery:
    $ echo disabled > /remoteproc/remoteproc0/recovery

    - in case you want to recover a crash, but keep recovery disabled
    (useful in debugging sessions when you expect additional crashes
    you want to debug):
    $ echo recover > /remoteproc/remoteproc0/recovery

    - enabling recovery:
    $ echo enabled > /remoteproc/remoteproc0/recovery

  • b5ab5e24e   remoteproc: maintain a generic child device for each rproc ... Browse Code »

    For each registered rproc, maintain a generic remoteproc device whose
    parent is the low level platform-specific device (commonly a pdev, but
    it may certainly be any other type of device too).

    With this in hand, the resulting device hierarchy might then look like:

    omap-rproc.0
    |
    - remoteproc0 for suggesting and
    discussing these ideas in one of the remoteproc review threads and
    to Fernando Guzman Lugo for trying them out
    with the (upcoming) runtime PM support for remoteproc.

  • 234e34058   simple_open: automatically convert to simple_open() ... Browse Code »

    Many users of debugfs copy the implementation of default_open() when
    they want to support a custom read/write function op. This leads to a
    proliferation of the default_open() implementation across the entire
    tree.

    Now that the common implementation has been consolidated into libfs we
    can replace all the users of this function with simple_open().

    This replacement was done with the following semantic patch:

    @ open @
    identifier open_f != simple_open;
    identifier i, f;
    @@
    -int open_f(struct inode *i, struct file *f)
    -{
    (
    -if (i->i_private)
    -f->private_data = i->i_private;
    |
    -f->private_data = i->i_private;
    )
    -return 0;
    -}

    @ has_open depends on open @
    identifier fops;
    identifier open.open_f;
    @@
    struct file_operations fops = {
    ...
    -.open = open_f,
    +.open = simple_open,
    ...
    };

    Expose several remote processor properties (name, state, trace buffer)
    that are helpful for debugging.

    This part is extracted to a separate patch just to keep the review load
    down.
