On most ABI files, the wildcards are used as <x>, instead of (x). Replace it to make it using a more standard wildcard. That helps get_abi.pl to convert it into a regex.

|
========== ===================================================
|
|
"boot" Boot the card OS image specified by the combination
|
|
of firmware, ramdisk, cmdline and bootmode
|
|
sysfs entries.

Possible values are:
|
|
|
|
========== ===================================================
|
|
"nop" shutdown status is not applicable, when the card OS
|

Description:
|
|
An Intel MIC device runs a Linux OS during its operation. Before
|
|
booting this card OS, it is possible to pass kernel command line
|
|
options to configure various features in it, similar to
|
|
self-bootable machines. When read, this entry provides
|
|
information about the current kernel command line options set to
|
|
boot the card OS. This entry can be written to change the
|
|
existing kernel command line options. Typically, the user would
|
|
want to read the current command line options, append new ones
|
|
or modify existing ones and then write the whole kernel command
|
|
line back to this entry.

|
Description:
|
|
The MIC drivers detect and inform user space about card crashes
|
|
via a heartbeat mechanism (see the description of
|
|
shutdown_status above). User space can turn off this
|
|
notification by setting heartbeat_enable to 0 and enable it by
|
|
setting this entry to 1. If this notification is disabled it is
|
|
the responsibility of user space to detect card crashes via
|
|
alternative means such as a network ping. This setting is
|
|
enabled by default.
