[RFC PATCH 0/8]: uninline & uninline

[RFC PATCH 0/8]: uninline & uninline

[Ilpo Järvinen]

Hi all,

I run some lengthy tests to measure cost of inlines in headers under
include/, simple coverage calculations yields to 89% but most of the
failed compiles are due to preprocessor cutting the tested block away
anyway. Test setup: v2.6.24-mm1, make allyesconfig, 32-bit x86,
gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13). Because one inline was
tested (function uninlined) at a time, the actual benefits of removing
multiple inlines may well be below what the sum of those individually
is (especially when something calls __-func with equal name).

Ok, here's the top of the list (10000+ bytes):

-110805  869 f, 198 +, 111003 -, diff: -110805  skb_put

-14896  199 f, 558 +, 15454 -, diff: -14896  sg_page 
-12870  36 f, 121 +, 12991 -, diff: -12870  le_key_k_type 
-12310  692 f, 7215 +, 19525 -, diff: -12310  signal_pending 
-11640  251 f, 118 +, 11758 -, diff: -11640  __skb_trim 
-11059  111 f, 293 +, 11352 -, diff: -11059  __nlmsg_put 
-10976  209 f, 123 +, 11099 -, diff: -10976  skb_trim 
-10344  125 f, 462 +, 10806 -, diff: -10344  pskb_may_pull 
-10061  300 f, 1163 +, 11224 -, diff: -10061  try_module_get 
-10008  75 f, 341 +, 10349 -, diff: -10008  nlmsg_put 

~250 are in 1000+ bytes category and ~440 in 500+. Full list
has some entries without number because given config doesn't
build them, and therefore nothing got uninlined, and the missing
entries consists solely of compile failures, available here:

  http://www.cs.helsinki.fi/u/ijjarvin/inlines/sorted

I made some patches to uninline couple of them (picked mostly
net related) to stir up some discussion, however, some of them
are not ready for inclusion as is (see patch descriptions).
The cases don't represent all top 8 cases because some of the
cases require a bit more analysis (e.g., config dependant,
comments about gcc optimizations).

The tools I used are available here except the site-specific
distribute machinery (in addition one needs pretty late
codiff from Arnaldo's toolset because there were some inline
related bugs fixed lately):

  http://www.cs.helsinki.fi/u/ijjarvin/inline-tools.git/

I'm planning to run similar tests also on inlines in headers that
are not under include/ but it requires minor modifications to
those tools.

ps. I'm sorry about the duplicates, old git-send-email's
8-bit-header problem bit me again. :-(

[RFC PATCH 1/8] [NET]: uninline skb_put, de-bloats a lot

[Ilpo Järvinen]

~500 files changed
...
kernel/uninlined.c:
  skb_put                       | +104
 1 function changed, 104 bytes added, diff: +104

vmlinux.o:
 869 functions changed, 198 bytes added, 111003 bytes removed, diff: -110805

This change is INCOMPLETE, I think that the call to current_text_addr()
should be rethought but I don't have a clue how to do that.

It should be possible to use a modular jhash.ko.  The things which you
have identified as clients of the jhash library are usually loaded as modules.

But in the case where someone does (say) NFSD=y we do need jhash.o linked into
vmlinux also.  This is doable in Kconfig but I always forget how.  Adrian, Sam
and Randy are the repositories of knowledge here ;)

Ok, even though its not that likely that one lives without e.g.
net/ipv4/inet_connection_sock.c or net/netlink/af_netlink.c? But maybe 
some guys "really know what they are doing" and can come up with config 
that would be able to build it as module (for other than proof-of-concept 
uses I mean)... :-/

> Adrian, Sam and Randy are the repositories of knowledge here ;)

Thanks, I'll consult them in this. I've never needed to do any Kconfig 
stuff so far so it's no surprise I have very little clue... :-)

I've one question for you Andrew, how would you like this kind of 
cross-subsys toucher to be merged, through you directly I suppose?

Thanks.  If it gets messy I'd just put lib/jhash.o in obj-y.  I assume it's
pretty small.

Sure, I can scrounge around for appropriate reviews and acks and can make

For very small functions like this own modules are quite expensive. First  
everything gets rounded up to at least one 4K page (or worse on architectures
with larger pages). That just wastes some memory. 

But then since modules live in vmalloc space they also need an own 
TLB entry, which are notouriously scarce in the kernel because often user space
wants to monopolize them all. So if you're unlucky and user space
is thrashing the TLB just a single call to this hash function will be an own 
TLB miss and quite expensive.

It would be better to just always link it in for this case.

My only concern was performance regressions, but it looks like it
doesn't effect anything from the few quick runs I've made.

Since we are putting sctp_add_cmd_sf() on the call stack, we might
as well get rid of sctp_add_cmd() and reduce it a bit more.

There was one call made anyway, it's a bit hard to see how it would hurt 
to push that BUG() deeper down (in fact, this is one of the easiest case 
in this respect, many other cases elsewhere that need uninlining don't 
currently make any calls with inlines).

IMHO it is definately better solution for archiving the size reduction,
I just didn't know before that the only sctp_add_cmd call could be 
converted.

That one was a really silly one.  The chance of not calling BUG() in
that one case was so small, that it didn't really make any sense from
the code robustness side.

Striking. How can this even happen? A callsite which calls

	dev_alloc_skb(n)

is just equivalent to

	__dev_alloc_skb(n, GFP_ATOMIC);

which means there's like 4 (or 8 if it's long) bytes more on the
stack. For a worst case, count in another 8 bytes for push and pop or mov on
the stack. But that still does not add up to 23 kb.

__dev_alloc_skb() is also an inline function which performs
some extra work. Which raises the question - if dev_alloc_skb()
is uninlined, shouldn't __dev_alloc_skb() be uninline as well?

I think you misunderstood the results, if I uninlined dev_alloc_skb(), it 
_alone_ was uninlined which basically means that __dev_alloc_skb() that is 
inline as well is included inside that uninlined function.

When both were inlined, they add up to everywhere, and uninlining 
dev_alloc_skb alone mitigates that for both(!) of them in every place 
where dev_alloc_skb is being called. Because __dev_alloc_skb call sites 
are few, most benefits show up already with dev_alloc_skb uninlining 
alone. On the other hand, if __dev_alloc_skb is uninlined, the size 
reasoning you used above applies to dev_alloc_skb callsites, and that
is definately less than 23kB.

Of course that could be done as well, however, I wouldn't be too keen to 
deepen callchain by both of them, ie., uninlined dev_alloc_skb would just 
contain few bytes which perform the call to __dev_alloc_skb which has the 
bit larger content due to that "extra work". IMHO the best solution would 
duplicate the "extra work" to both of them on binary level (obviously 
not on the source level), e.g., by adding static inline ___dev_alloc_skb() 
to .h which is inlined to both of the variants. I'm not too sure if inline 
to __dev_alloc_skb() alone is enough in .c file to result in inlining of 
__dev_alloc_skb to dev_alloc_skb (with all gcc versions and relevant 
optimization settings).

The results are right under your nose already... ;-)
See from the list of the series introduction:

  http://marc.info/?l=linux-netdev&m=120351526210711&w=2

IMHO more interesting number (which I currently don't have) is the 
_remaining_ benefits of uninlining __dev_alloc_skb after
dev_alloc_skb was first uninlined.

I've measured this now... Without many debug CONFIGs (in v2.6.25-rc2-mm1), 
the dev_alloc_skb is much less than 23kB:

    382 funcs, 157 +, 12335 -, diff: -12178 --- dev_alloc_skb
    dev_alloc_skb                 |  +37

...and on top of that, I got only this:
    48 funcs, 111 +, 836 -, diff: -725 --- __dev_alloc_skb

Not that impressive compared with many much worse cases (wasn't a big 
surprise because there were fewer callsites for the latter).

Anyway, would I uninline it (or one some another function that has such 
two variants that are good candidates for uninlining), should I try to 
avoid deepening the call-chain by two functions? To me it seems that only 
way to fool gcc to do that for sure would be using some trick like this:
Rename __dev_alloc_skb to ___dev_alloc_skb in the header (with appropriate
don't ever call this due to bloat comment added) and both __dev_alloc_skb 
and dev_alloc_skb could then be made to call that one in .c file. 
Otherwise I'm not that sure gcc wouldn't try to be too clever if I just 
use inline in .c file.

This is a surprise.  I expect that the -mm-only
profile-likely-unlikely-macros.patch is the cause of this and mainline
doesn't have this problem.

If true, then this likely/unlikely bloat has probably spread into a lot of
your other results and it all should be redone against mainline, sorry :(

(I'm not aware of anyone having used profile-likely-unlikely-macros.patch
in quite some time.  That's unfortunate because it has turned up some

It surprised me as well, there were something like 10 bytes I just

picked textual output :-)... Hmm, I'll add logging for the disassembly of 
the uninlined stuff into the next run, that won't cost too much...

Ahaa, this explain it, I suspected that there was something (un)likely 
related elsewhere as well, no wonder why I couldn't reproduce the 25 bytes 
result in my quick copy-pasted non-kernel test...

It isn't that troublesome to redo them, it's mainly automatic combined 
with impatient waiting from my behalf :-)... The spreading problem is 
probably true, to some extent. I did some runs also with carefully 
selected CONFIG.*DEBUG.* off under include/net/ earlier, in general it 
made very little difference, if something bloats, it usually does that 
regardless of .config. There are probably couple of exceptions when the 
size is on the boundary where it's very close of being useful to uninline 
it.

One interesting thing in there was that the largest offenders are quite 
small per call-site but due to vast number of them even a small benefit 
buys off a lot in kernel wide results. I suspect the differences due to 
(un)likely will be negligle, because the IS_ERR with all its trivialness 
is now mostly -15, so anything clearly larger than that will likely still 
be a win x n (where n is quite large).

Anyway, I'll see when I get the new set of tests running... :-) I'd prefer 
with CONFIG.*DEBUG off to get larger picture about non-debug builds too
(especially the scatterlist.h things interest me a lot), do you think that 
would do as well?

Thanks for your comments, I found them very useful.

Shouldn't they only have overhead when the respective CONFIG is enabled?

Is there any reason they couldn't just be merged to mainline? 

I think it's a useful facility.

I uninlined those with allyesconfig. I'll anyway try later on without a 
number of debug related CONFIGs.

ummm, now why did we made that decision...  I think we decided that it's
the sort of thing which one person can run once per few months and that
will deliver its full value.  I can maintain it in -mm and we're happy - no
need to add it to mainline.  No strong feelings either way really.

It does have the downside that the kernel explodes if someone adds unlikely
or likely to the vdso code and I need to occasionally hunt down new
additions and revert them in that patch.  That makes it a bit of a
maintenance burden.

Apparently nobody has been doing it for a while. :-) Last time I did it it
was around the submission time and I actually patched it into mainline
kernel to do so. Not particularly hard to do, but sitting in mm-only does
make it a bit harder, and there are the vdso problem you just mentioned that
one has to fix for himself if it exists in mainline.

Is it possible to catch this automatically, like, by re-defining
likely/unlikely to the raw form in specific file(s)?

Sure it would be possible to define a IN_VDSO symbol in all vdso
related files and then do that. Might be useful for other things
too. vdso has some very specific requirements.

I think it exploded again, for some other reason...

I just gave it a try just for grins-n-giggles.  The resulting kernel got loaded
by grub, the screen cleared, and about 5 seconds later it rebooted. Never got
as far as putting up penguin icons.  Tried again with netconsole, early_printk=vga,
and initcall_debug, and it *still* didn't live long enough to produce anything
resembling output.

2.6.25-rc2-mm1, x86_64 on a Dell Latitude D820 laptop, T7200 Core2 Duo.

Attached is my *working* config (I'm using it as I type this).  Changing to
'CONFIG_PROFILE_LIKELY=y' and rebuilding produces wreckage....
