In Alchemy RT_TASK_INFO has a member struct threadobj_stat which is
undocumented
(https://xenomai.org//documentation/xenomai-3/html/xeno3prm/structRT__TASK__INFO.html).
Looking at the source of copperplate/threadobj.h
(https://xenomai.org//documentation/xenomai-3/html/xeno3prm/threadobj_8h_source.html)
, it turns out it has these members:
struct threadobj_stat {
ticks_t xtime;
ticks_t timeout;
uint64_t msw;
uint64_t csw;
uint64_t xsc;
int cpu;
int schedlock;
unsigned int status;
uint32_t pf;
};
I could not find a documentation of what they are and even a straight forward
comparison with rt_task_info from Xenomai 2.6
(http://www.xenomai.org/documentation/trunk/html/api/structrt__task__info.html)
does not give an idea of what all of these are (e.g.: timeout, xsc, cpu,
schedlock).
The migration guide (https://xenomai.org/migrating-from-xenomai-2-x-to-3-x/)
only says "other fields which represent runtime statistics are now avail from a
core-specific stat field sub-structure."
Thanks,
Giulio
