turbostat reports C-states of all CPU cores, and includes entries for each hyper-threaded core as well. Often enough the two logical cores on a single physical core will list different C state percentages. Does that make any sense?
Is this reporting the c-states of the few duplicated parts... (8 Replies)

Hi guys,
Can you help me please to find an appropriate course of UNIX in the United States.
Also, can you provide me some information about the schools or institutes that offer it in the U.S.
Thanks, (0 Replies)
I am trying to write my own Unix compliant (SUSv4) OS - Just a hobby OS, nothing serious. While going through the standard, I couldn't find any explicit information on process states. What I could find was (excluding the real-time considerations)-
From this it can be inferred that the... (2 Replies)
PSERIALIZE(9) BSD Kernel Developer's Manual PSERIALIZE(9)NAME
pserialize -- passive serialization mechanism
SYNOPSIS
#include <sys/pserialize.h>
pserialize_t
pserialize_create(void);
void
pserialize_destroy(pserialize_t psz);
int
pserialize_read_enter(void);
void
pserialize_read_exit(int s);
void
pserialize_perform(pserialize_t psz);
DESCRIPTION
Passive serialization is a reader / writer synchronisation mechanism designed for lock-less read operations. The read operations may happen
from software interrupt at IPL_SOFTCLOCK.
FUNCTIONS
pserialize_create()
Allocate a new synchronisation object.
pserialize_destroy()
Destroy the synchronisation object. No synchronisation activity should happen at this point.
pserialize_read_enter()
Enter the critical path of the reader side. Returns an IPL value, which must be passed to pserialize_read_exit(9). Protected code
path is not allowed to block.
pserialize_read_exit()
Exit the critical path of the reader side. Takes the IPL value returned by pserialize_read_enter(9).
pserialize_perform()
Perform the passive serialization on the writer side. Passing of this function ensures that no readers are in action. Writers must
be additionally serialized with a separate mechanism, e.g. mutex(9). Operation blocks and it may only be performed from thread
context.
EXAMPLES
Typical code fragment in the writer side:
mutex_enter(&writer_psz_lock);
/*
* Perform the updates (e.g. remove data items from a list).
*/
...
pserialize_perform(object->psz);
/*
* At this point it is safe to destroy old data items.
*/
mutex_exit(&writer_psz_lock);
CODE REFERENCES
The pserialize is implemented within the file sys/kern/subr_pserialize.c.
