From: Jesper J. <juh...@di...> - 2005-04-26 21:34:34

The preempt_count member of struct thread_info is currently either defined
as int, unsigned int or __s32 depending on arch. This patch makes the type
of preempt_count an int on all archs.
Having preempt_count be an unsigned type prevents the catching of
preempt_count < 0 bugs, and using int on some archs and __s32 on others is
not exactely "neat" - much nicer when it's just int all over.
A previous version of this patch was already ACK'ed by Robert Love, and
the only change in this version of the patch compared to the one he ACK'ed
is that this one also makes sure the preempt_count member is consistently
commented.
Please consider applying.

Well, guess it depends how much we like s32 over int. Both are identical on all supported architectures, so it is just a style issue, really. If m68knommu is the only arch needing asm/typed.h included, I'd so just include it. If more and more arches need it, just go with int. It is probably an easier sell. Robert Love |

Would this make "int" prefered after all or should I just include asm/types.h where needed or just include it everywhere? seems logical that the file that uses header includes it directly instead of it getting included implicitly by other headers (like i386 where thread_info.h includes asm/page.h that then includes asm/mmx.h that then includes linux/types.h that finally includes asm/types.h). Personally I'd just add the asm/types.h include to all the thread_info.h files (or go back to using int) - what's your preference? -- Jesper |

Replying to myself here since the initial mail got no response. Here's
hoping that it showing up on the list again draws some comments :-)

While looking through the tree and checking out possible signedness issues
pointed out to me by gcc -W I came across this one :
kernel/timer.c:464: warning: comparison between signed and unsigned
The issue there is this little bit of code :
[...]
462 u32 preempt_count = preempt_count();
463 fn(data);
464 if (preempt_count != preempt_count()) {
[...]
gcc is complaining about that since preempt_count in struct thread_info
(which is what preempt_count() returns) is a signed integer. Initially I
thought "that's a bit sloppy, I'll just make the local variable a s32 and
that should be that", but then I looked a little closer at struct
thread_info for the different archs, and found that the type used differs
between archs and it's not even a signed type on all (s390 being the
unsigned exception). So all of a sudden fixing up this little warning was
not so simple after all.
The different types used for struct thread_info.preempt_count are
__s32, int and unsigned int.
Why are different types used for struct thread_info.preempt_count? Would
it not make sense to make it a __s32 or plain int on all archs? I would
think that consistency here would be a good thing.
And why on earth is it an unsigned int on s390? It seems to me that that
makes it impossible to catch bugs where preempt_count is decremented below
zero.
Any reason not to apply a patch like this one?
my choice of 'int' over '__s32' was pretty arbitrary - as far as I know we
don't support any archs where 'int' is less than 32bits, do we? So I
figured that using a plain int type should give us at least 32 bits
everywhere as well as using the given platforms fastest type. If any of
the archs have <32bit int types, then I guess __s32 would be a better
choice.

Actually, any thread of execution:
- interrupt processing
- system call
- kernel thread
can disable kernel preemption. As George notes below - it preemption
should be disabled only when you MUST protect some data.

Let me use a simple case with the following patch (applied to 2.6.10-mm1)
as an example:
--- net/ipv4/tcp_minisocks.c.orig 2004-12-15 14:02:23.000000000 -0600
+++ net/ipv4/tcp_minisocks.c 2004-12-15 14:02:59.000000000 -0600
@@ -414,7 +414,7 @@
#define TCP_TWKILL_SLOTS 8 /* Please keep this a power of 2.
*/
#define TCP_TWKILL_PERIOD (TCP_TIMEWAIT_LEN/TCP_TWKILL_SLOTS)
-#define TCP_TWKILL_QUOTA 100
+#define TCP_TWKILL_QUOTA 30
static struct hlist_head tcp_tw_death_row[TCP_TWKILL_SLOTS];
static DEFINE_SPINLOCK(tw_death_lock);
There is also code later that does this:
while (tcp_do_twkill_work(i, TCP_TWKILL_QUOTA) != 0) {
if (softirq_need_resched()) {
spin_unlock_bh(&tw_death_lock);
schedule();
spin_lock_bh(&tw_death_lock);
}
So it does not check for a reschedule for 100 (30 with the patch)
iterations inside tcp_do_twkill_work. Note that the work still
has to be done in either case if the preemption occurs.
[a side note - this example is coded pretty strange if you track
all uses of tw_death_lock and should probably be cleaned up]
There are A LOT of these kinds of examples in the Linux kernel.
Many have been fixed. There is no guidance that I am aware of on
the timing / limits for loops for such constructs.

What one user sees as "hogging" the CPU, another sees as efficient
use of the CPU. If I had a big iron network server, the patch I
show above makes the system less efficient. But for me, it improves
latency for my real time applications.

I wish I could get 10-100 microseconds. If my RT task gets preempted for
less than 1000 microseconds I will be pretty happy.

I agree.

This is certainly a traditional definition of "CPU hog". Note the OP has
asserted that a [kernel?] process can "stubbornly continue to perform
its task" (which I provided an example). If that is an device driver
or file system code in the kernel, it can still be a "hog" for the RT
applications.

For a thread, yes. For one of the other items I mentioned (interrupt
or system call), I disagree. The scheduler doesn't usually get involved
in cases like the example I illustrated unless it is explicitly coded
to allow it.

If its a kernel thread a value like 40 msec may actually be a
good guideline. However for something that runs in the context of
a (possibly RT) user application (e.g., interrupt) - that is an
extremely long period of time. I run tasks at 80 HZ (12.5 msec period)
so if that task gets stopped for a millisecond (or 15 times for
100 usec each - yes I've measured that) in that period, I start to
get worried.

I think we are in violent agreement on this issue.
The other point I might make is that an RT application developer will
also do what they can to tightly control non RT applications. For
example, if you start a lot of network I/O from a non RT application,
that can cause a number of interrupts to occur, impacting the RT
application.

If you are talking about kernel code, we (rt interested folks) are looking for preemption times in the 10-100 microsecond region. To do this most locks (spin locks and reader/writer locks) are being changed to mutexes which will yield control on demand. The notion is that what needs protection is the data and that is what a mutex does. As it turns out, a preemption lock is rather cheap (only a bit is set/reset) so it is the preferred way (given a UP machine) to lock data for quick access (such things as popping an element from a list), while the mutex is best for longer held things. Still, your question seems to be more of a scheduler question. The notion of a CPU hog is defined there and changes the relative priority of non rt tasks to best optimize the system. This, however, is a long term thing and take some time to react.

Kernel modules should do only the locking needed to protect the data they are working with. If they directly interact with hardware, they will also need to protect that interaction with the necessary locks. In general, they should expect to be preempted at ANY instruction. If they loose control, the data should still be protected until they get control again. The way to do this is with spin locks and, sometimes, preemption disables. A lot has been written on how to do this and the issues involved. Such code should turn off interrupts only on when absolutely needed and then for as short a time as possible. -- George Anzinger ge...@mv...

Mark, George, Thank you for your replies. I now realize that your (much appreciated) answers demonstrate my somewhat flawed questions. Perhaps these question are closer to the mark: I assume that kernel preemption can be disabled at some granularity; perhaps per kernel process. Hypothetically, assume that a process is in a state that it could easily relinquish control, but instead it stubbornly continues to perform its task. In such a state, it would seem to me that a process might be capable of "hogging" the CPU, inappropriately starving other kernel processes out of CPU time. If my assumptions are correct; my question is this... What would be considered a proper Maximum CPU time slice for such a process; (when exceeding such, the process would be considered a "CPU hog"). I realize the arguments on both sides; that sometimes it would be better to "complete the task" than relinquish control, etc., and that perhaps there should not be an exact maximum time slice. I am working on a list of guide-lines for Linux kernel module developers; and this "Maximum CPU Time Slice" issue was brought to my attention. Initially, I assumed (perhaps incorrectly), that this value should be similar to the maximum allowed by kernel process preemption. Obviously, I was hoping for an answer somethin like "40ms (or so)". However, your previous replies helped me better understand the complexity of trying to tackle this issue that way. Any help, or suggestions, are appreciated. -adam |

> Specifically, how long will the 2.6 kernel tolerate a preemptable > kernel process before attempting to preempt it? Preemption of the kernel happens in a few different ways (assuming CONFIG_PREEMPT): - not in a critical region, preemption occurs immediately - in a critical region, check done if "need_resched" and if so, release the locks & try again later - a critical region ends Note the hardware also has to be "nice" for a preemption to occur. I have demonstrated > 1 msec latencies when using udma4 or udma5 on an IDE disk drive on my SMP PC's. Setting the disk to udma2 fixes that particular symptom. So there is no "formula" to be found. Part of Ingo Molnar's realtime-preempt patch modifies the behavior of loops in a critical region, checking for a rescheduling condition more frequently. Some areas patched include the file system, audio, and network drivers. Now there may also be some scheduling bugs on SMP systems. I have reported for some time "starvation" of a non RT application on an SMP system running a single RT application & a nice'd application. The non RT application did not preempt the nice'd application. There was a similar problem if you had more than one RT application but I think Ingo has fixed that one. This information is based on my testing of RT patches up through 2.6.10 (we've stopped there for now to let the dust settle). --Mark H Johnson <mailto:Mar...@ra...> |

As far as I know, if a process is preemptable and there is work at a better priority, it happens NOW, no waiting... Now you are into the notion of priority which is a scheduler issue, not a preemption one.

I am doing some research on the 2.6 kernel; and I am having difficulty locating information (in documentation form) specific to kernel process preemption. Specifically, how long will the 2.6 kernel tolerate a preemptable kernel process before attempting to preempt it? Is this tolerance based on a formula, a constant value and/or configured by a system administrator? If based on a formula, what is the formula? Best wishes; - Adam Jerome / Novell Inc.
