Sometimes there is a different view of the AP status word
needed. So here is slight rework of the struct ap_queue_status
to open up the possibility to have different ways of accessing
the AP status bits and fields.
The new struct ap_queue_status
struct ap_queue_status {
union {
unsigned int value : 32;
struct {
unsigned int status_bits : 8;
unsigned int rc : 8;
unsigned int : 16;
};
struct {
unsigned int queue_empty : 1;
unsigned int replies_waiting : 1;
unsigned int queue_full : 1;
unsigned int : 3;
unsigned int async : 1;
unsigned int irq_enabled : 1;
unsigned int response_code : 8;
unsigned int : 16;
};
};
};
comprises the old struct ap_queue_status but extends it
to have this also accessible as an unsigned int required
for example for a simple print or trace of the whole value.
Note that this rework is fully backward compatible to the
existing code exploiting the struct ap_queue_status.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
