This patch adds the specification for /sysfs/devices/.../coredump which allows user-space to trigger a device coredump obtaining binary data from the device for (fault) analysis. It relies on CONFIG_DEV_COREDUMP being enabled. Signed-off-by: Arend van Spriel <aspriel@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Description:
|
|
The /sys/devices/.../coredump attribute is only present when the
|
|
device is bound to a driver, which provides the .coredump()
|
|
callback. The attribute is write only. Anything written to this
|
|
file will trigger the .coredump() callback.
|
|
|
|
Available when CONFIG_DEV_COREDUMP is enabled.
