2.6.22-rc5 regression

2.6.22-rc5 regression

[Carlo Wood]

I cheered too soon ... I just tested 2.6.22-rc5 and it hangs
again at the same point, right after printing:

agpgart: Detected an Intel 965G Chipset.

So far I tested:

Re: 2.6.22-rc5 regression

[Carlo Wood]

Because I CC new people, let me summarize:

2.6.18 works fine. Most kernels after that print
"agpgart: Detected an Intel 965G Chipset."
and then either hang (I have to hard reset them), hard
reset by themselves or print one or two more lines mostly
related to hardcrashes (memory page faults or otherwise)
and hang then. This can vary from boot to boot even
with the same kernel.

Some kernels don't hang. They never hang - they always work.

Kernels that work do NOT print "agpgart: Detected an Intel
965G Chipset." (All I know is that I have an ASUS P5B motherboard
with a iP965, whether it's this 'G' or not I don't know).


This is the regression that 'git bisect' comes with:

    mm: Fix memory/cpu hotplug section mismatch and oops.

    When building with memory hotplug enabled and cpu hotplug disabled, we
    end up with the following section mismatch:

    WARNING: mm/built-in.o(.text+0x4e58): Section mismatch: reference to
    .init.text: (between 'free_area_init_node' and '__build_all_zonelists')

    This happens as a result of:

            -> free_area_init_node()
              -> free_area_init_core()
                -> zone_pcp_init() <-- all __meminit up to this point
                  -> zone_batchsize() <-- marked as __cpuinit   fo

    This happens because CONFIG_HOTPLUG_CPU=n sets __cpuinit to __init, but
    CONFIG_MEMORY_HOTPLUG=y unsets __meminit.

    Changing zone_batchsize() to __devinit fixes this.

    __devinit is the only thing that is common between CONFIG_HOTPLUG_CPU=y and
    CONFIG_MEMORY_HOTPLUG=y. In the long run, perhaps this should be moved to
    another section identifier completely. Without this, memory hot-add
    of offline nodes (via hotadd_new_pgdat()) will oops if CPU hotplug is
    not also enabled.

The obvious question of course is whether actually reverting this
changeset fixes your problem? I would be very surprised if it did.

If it does make a difference, please provide the values for
CONFIG_HOTPLUG, CONFIG_MEMORY_HOTPLUG and CONFIG_HOTPLUG_CPU from your
.config.

I would wager that you only have CONFIG_HOTPLUG=y, in which case, the
only difference over previous kernels will be that zone_batchlist() is no
longer flagged as __init, and so it won't be freed -- this was the reason
for the "special section" comment in the changeset, as currently it's
left hanging around for folks that aren't doing cpu/memory hotplug, since
__devinit was the closest that both cpu and memory hotplug had in common.

I can't imagine that this would impact you at all, though.

Having a git commit Id, like d09c6b809432668371b5de9102f4f9aa6a7c79cc,
how can I create a .diff file from that?

I think git bisect made an error... as you can see for yourself
with the list of tested git Id's that I gave - it didn't test
both sides of that patch imho. If you tell me how to extract a patch
then I'll manually unapply it to some failing kernel revisions and
see if that makes a difference.

if you just want to test that single change.

Assuming that reverting that patch makes no difference, can you provide
the output of 'git bisect log'?

Please forgive my git fanboyism, but assuming you have no

$ git revert -n d09c6b809432

Hmm. Possible. However, I *really* would need the git bisect log to see 
what's up. So far, we have never seen a bug in "git bisect" that wasn't 
either due to the user specifying path-names to limit the testing (and the 
bug not being in that set of path-names), or the user not realizing that 
with non-linear history the "git bisect" is actually a fairly complex op.

That said, "git bisect" _can_ give the "wrong" results in the sense that 
the commit it points to may not be the one you are actually looking for, 
if:

 - the bug is sporadic, and not entirely repeatable, and a kernel you 
   marked as good wasn't really good, your test just didn't happen to 
   catch it that time around.

 - the bug comes and goes, and the commit that "git bisect" pinpoints may 
   well *show* the bug, but may not be the *cause* of the bug (ie there 
   might be two or more independent things that have to come together for 
   the bug to trigger, and as a result there is not a "single" commit that 
   acts as a clear boundary)

But hey, a bug in "git bisect" is certainly _possible_. I just consider it 
fairly unlikely by now.

You seem to not actually have used "git bisect" to generate this list.

Quite frankly, the most likely cause for the bad bisection result is that 
you have not used "git bisect" at all to let it pick the bisection points. 
That really doesn't work. If you start giving "git bisect" points to test 
that aren't "within" the space of points you had already told git bisect 
about, you're no longer bisecting, you're giving it random points.

> I'd appreciate any suggestions or questions at this point, as I have no

If you do a real "git bisect", and don't just give it random points that 
you want to check (you obviously _do_ need to give it one "good" and one 
"bad" initially, but after that you *have* to pick a point that is within 
the query space), you'll not get any sensible values out of git bisect.

"git bisect" will also give you a log in ".git/BISECT_LOG", which others 
can use to follow your bisection. That might be useful to see.

I had already done a git bisect reset :/

I realize that it is non-linear - and I didn't do anything to "speed
things up". Just build -> boot -> git bisect good/bad -> build etc.

I don't believe that either of these is the case. I have booted
about 8 different kernel revisions several times (most three times),
alternating between them (not the same three times on a row) and the
ones that boot correctly always booted correctly, while the ones that
hung, always hung (although in a totally reproducable way).

Nevertheless, it is not 100% impossible. I have the feeling that it
MIGHT be related to the fact that I have 4 CPU's - and that perhaps some
race condition is involved. And if that is the case, then there might be
some kernel version where boot/not-boot is less reliable then with the
eight I tested - apart from that three times isn't very much (but doing
it for four good kernels and two bad kernels, it still is a reasonable
indication for reproducability).

I didn't -- what is the command to generate a list like this with git?

Heh - now you are insulting me :p  I said I did, and I did.
The reason that I made that list manually is because wanted to have more
overview. I use this alias to build the kernels:

hikaru:/usr/src/kernel/git/linux-2.6>alias build
alias build='cp /boot/config-2.6.22-rc4-hikaru-amd64 .config &&
make-kpkg clean && VER=$(date +"%Y%m%d%H%M") && BRANCH=$(git branch |
grep "^\*" | sed -e "s/\* //") && NAMEEXT="-$BRANCH-$(git rev-list
--max-count=1 $BRANCH)-$(dpkg-architecture -qDEB_HOST_ARCH)" &&
make-kpkg --revision=$VER --append-to-version=-$NAMEEXT --rootcmd
fakeroot clean && make-kpkg --revision=$VER --append-to-version=$NAMEEXT
--rootcmd fakeroot --initrd kernel_image modules_image'

That results in debian kernel package names like:

Heh - hopefully you have 20" monitors like met :p

However - it didn't give me an overview of the git bisect good/bad
process. Therefore I used 'gitk -all' and it's search function to
find all the kernels that I tested and put them in a file, such
creating that list I posted here. If there is a way to generate
this list with a command, please tell me :)

Some online documention said you can use git reset --hard gitId to
choose a different point nearby what git bisect 'suggests' to test next.
I didn't do that in this case however.

I suppose you mean: ... then you WILL get sensible values out of git
bisect. But, since I already did a real "git bisect" without giving it
random points, I am afraid you jumped conclusions.

No such file exists (anymore).

However, I can easily reproduce it. From my history file I can see that I started with:

   git bisect start
   git bisect bad v2.6.22-rc5
   git bisect good 99f9f3d49cbc7d944476f6fde53a77ec789ab2aa

I wrote everything down on paper (the git id's and whether they
were good or bad), so I can reproduce it with:

commit d09c6b809432668371b5de9102f4f9aa6a7c79cc

    mm: Fix memory/cpu hotplug section mismatch and oops.

    When building with memory hotplug enabled and cpu hotplug disabled, we
    end up with the following section mismatch:

    WARNING: mm/built-in.o(.text+0x4e58): Section mismatch: reference to
    .init.text: (between 'free_area_init_node' and '__build_all_zonelists')

    This happens as a result of:

            -> free_area_init_node()
              -> free_area_init_core()
                -> zone_pcp_init() <-- all __meminit up to this point
                  -> zone_batchsize() <-- marked as __cpuinit                     fo

    This happens because CONFIG_HOTPLUG_CPU=n sets __cpuinit to __init, but
    CONFIG_MEMORY_HOTPLUG=y unsets __meminit.

    Changing zone_batchsize() to __devinit fixes this.

    __devinit is the only thing that is common between CONFIG_HOTPLUG_CPU=y and
    CONFIG_MEMORY_HOTPLUG=y. In the long run, perhaps this should be moved to
    another section identifier completely. Without this, memory hot-add
    of offline nodes (via hotadd_new_pgdat()) will oops if CPU hotplug is
    not also enabled.

Sorry - that should be "although NOT in a totally reproducable way"

Hey, fair enough.

That said, your "git bisect" really *does* act oddly.

You seem to have a modified tree! What are those modifications to the 
blackfin macros.h etc files?

You *should* have gotten this:

	[torvalds@woody linux]$ git bisect start
	[torvalds@woody linux]$ git bisect bad v2.6.22-rc5
	[torvalds@woody linux]$ git bisect good 99f9f3d49cbc7d944476f6fde53a77ec789ab2aa

but those are just off by one, at least (127 vs 128 commits left).

And that's totally broken. Even if I don't use the "9808901b6" commit, and 
use your "cf686762" commit, I get:

	[torvalds@woody linux]$ git bisect good cf68676222e54cd0a31efd968da00e65f9a0963f

Notice? The "127 revisions left to test after this" has become "63 
revisions left to test after this".

That number should be cut in half each time. And you shouldn't get some 
strange dirty tree indications.

It might be worth it just making sure your git is ok. It really is acting 
oddly. What version is it?

I never (manually) changed anything - so, this should be the result
of the fact that I use the same directory tree to (re)build the kernel
every time.

That 'D' means they are deleted I'd think - so the changes are clear.

I am sorry, but I am totally new to git - I know cvs and svn (and even
then I never used branches :(), but I don't know how to find out what
those differences are with git.
I could start looking on the web - but it's a fact that I don't even
know what I would look for: in order to create a diff one needs two
points. No doubt one point is the current state of my local copy,
but what would that other point be to compare with?
If you would be so kind to ask things like: What is the result of
this or that command, when it comes to git, then I will be faster
and more accurate to tell you :).  I added the result of 'git diff'
below.

Well,... when, and because, it's not a linear thing as you mentioned
before - it's not necessarily precisely a cut into half... so I thought,
seeing those weird (not half) numbers that that was the cause.

git version 1.4.4.4

I am using Debian (suite 'testing') and trying to be a debian purist -
so it isn't like I can easily upgrade to 1.5.x : there is no debian
package for that version in 'testing'.

Nevertheless, if you think it's important - then I can download and
compile a tar ball of course - certainly when I don't have to install
it to test it.

You're correct - "git bisect" will not always be able to find an exact 
half-way point, and I was wrong to imply that it will always be quite that 
close.

It's easily off by a few commits because of merges that make it harder to 
find a good bisection point, but it should never (practically) be off by 
quite as much as you saw. 

For example, I could expect that from 127 commits, it would go down to 70 
rather than 64. But not to 110 - not unless there are some *really* 
strange patterns with lots of criss-crossing merges.

And indeed, for me, using the same commit ID's as you used, I see a nice 
bisection to just about exactly half.

You really do want to use git-1.5.x these days.

It does look like 1.4.4.4 may have a bug, although I'm really surprised: 
we've certainly tweaked stuff in bisection, but I and others have used 
"git bisect" since long before the git-1.4 days, and it has always worked 
ok. So I wonder if it's something specific to that debian build.

Or possibly to the fact that you have some other dirty state (you might 
want to do a "git diff HEAD" to see what the changes are, and maybe a "git 
checkout -f" to get rid of any differences)

Ok, something deleted an empty file. Probably "make distclean". Our "make 
clean" is sometimes too aggressive, and we generally shouldn't have empty 
files.

That one also has been actually deleted. And "make distclean" doesn't do 
that. You have something else going on.

Probably make-kpkg removing the in-tree instructions for building debian 
packages so that its own rules will be used instead or something like 
that.

Well, it does indeed.

Without changing ANYTHING to my linux-2.6 source tree - I just
installed git 1.5.2.1 and now it behaves the way you describe.

Conclusion: the weird behaviour that you think was wrong is
totally due to git 1.4.4.4.

I'll redo the bisect with this new git.

Ok. I'll bounce a note to Junio just due to curiosity in case he goes 
"ahh, yeah, it was that known bug", but I'll otherwise ignore this.

Git-1.5.x is such a radically better version (not because it fixes this 
bug, but because we fixed a number of other issues, notably some very 
basic usability things), that I think any git users should really upgrade 
to a newer version.

IOW, there's simply no reason to stay on anything older (git has always 
been backwards compatible since very early on, so upgrading to a newer 
version of git won't break anything, although some of the new UI's might 
obviously cause you to do things differently).

    [AGPGART] intel_agp: fix device probe
    
    This patch trys to fix device probe in two cases. First we should
    correctly detect device if integrated graphics device is not enabled
    or exists, like an add-in card is plugged. Second on some type of intel
    GMCH, it might have multiple graphic chip models, like 945GME case, so
    we should be sure the detect works through the whole table.
    
    Signed-off-by: Wang Zhenyu <zhenyu.z.wang@intel.com>
    Signed-off-by: Dave Jones <davej@redhat.com>


The result of this patch is that the kernel starts to print
"agpgart: Detected an Intel 965G Chipset." again with the usual
disastrous results. Now, that doesn't mean that this patch is
wrong - but it explains why the problem returns after this patch.

Right, without this patch, probing was broken, so we never matched
an agp driver to the chipset.  The question remains though, why
the initialisation of the chip is so broken.

Heh.

Yeah, at this point I think we can pretty much guarantee that your problem 
is one of two cases:

 - either a bit random, and depends on some timing thing, and one of the 
   kernels you marked "good" wasn't really.

   It's not likely that you marked a good kernel bad, of course, since 
   with a good kernel, everything should have always worked, but with a 
   bad kernel and a bug that isn't entirely reproducible, you'd mark it 
   "good" by mistake - because it just randomly didn't show the problem.

OR

 - we actually have two different commits that introduce the problem for 
   you, and it comes and goes, and the bisection doesn't work, because 
   there isn't a clear "this side works, that other side does not" 
   situation.

For example, later on you say:

> Personally I am convinced that the real problem is with
> 8888985144db8f4cb7e56154b31bdf233d3550bf

but if you look at your commit log, you have:

> # bad: [25971f68d392f1816e21520e9e59648403b0bdad] [PARISC] fix section
> # mismatch in ccio-dma
> git-bisect bad 25971f68d392f1816e21520e9e59648403b0bdad

Notice? You said that 25971f68d392f1816e21520e9e59648403b0bdad was bad, 
but that is *before_ the 8888985144db8f4cb7e56154b31bdf233d3550bf commit. 
Do a

	gitk 25971f68d3..8888985144

to see that part of the history.

So maybe you didn't test that kernel properly? And maybe it really is 
random, and something has happened that just makes it happen more often?

Also, some *really* nasty bugs end up being about bad initialization, and 
it turns out that what happens more is not which kernel you run, but what 
the *previous* kernel you ran is, because it left some device driver state 
that the bug doesn't clean up!

Anyway, can you try that 25971f68d3 kernel one more time? You marked it 
bad, but if that kernel is bad, then the commit you are pointing to is 
*not* the culprit.

Yep, the device table patch doesn't change any function, so your problem
started from when 965G support patch has been in kernel. 

Carlo, pls try a kernel param of "pci=nommconf" to see if that could
fix your hang. There might be a BIOS bug, as similar issue also happen
like https://bugzilla.novell.com/show_bug.cgi?id=228683

I think for i965 we could have following patch to fix this, we may
fail if no IGD device got detected.

Yes

Looking a bit closer to the bisect myself, I note that 
25971f68d392f1816e21520e9e59648403b0bdad and
aba297927d1d558c7a94548135133bdf9172708a are part of
a branch that is derived from a very "old" revision.
git bisect assumes that such an old revision is good,
but in fact - that was already bad as well, because
the history of this bug is:

2.6.22-rc5 BAD
2.6.22-rc4+somethingelse BAD
2.6.22-rc4+something GOOD
2.6.22-rc4 BAD
...
2.6.18-rc1 BAD
2.6.18 GOOD

Thus: BAD BAD BAD GOOD GOOD BAD BAD

and git bisect can't handle that, even though I started
with a 'good' start point and a bad start point at the end.

This part is thus based upon a revision so old that it was bad again,
even before the small period that it was good.

No, it is really 100% reproducible.

That bugreport looks EXACTLY like the problem that I ran into.
Note that they have the same motherboard as me: ASUS P5B Deluxe

I will try pci=nommconf in a moment. It isn't the best workaround
however as it should reduce the available RAM from 4GB to 3GB.
agp=off would be a better workaround.

This does not fix the problem.

yeah, the error message needs to be fixed only if AGP cap
exists. I was checking with other GMCH data sheets, we'd better 
disable AGP for chip that has no AGP port. I will send out
another patch later.

[PATCH][AGPGART] intel_agp: don't load if no IGD and AGP port

[Wang Zhenyu]

Thanks Carlo to report this problem. The following patch should fix
his and potential issue.

[AGPGART] intel_agp: don't load if no IGD detected and no AGP port

After i915 chip, GMCH has no AGP port. Origin bridge driver in device
table will try to access illegal regs like APBASE, APSIZE, etc. This
may cause problem.

So mark them as NULL in the table, we won't load if no IGD got detect
and bridge has no AGP port.

Thanks for fixing it Wang :)
I have to admit that the Real Reason I did put time into this is because
I wanted to be sure that when debian upgrades 'testing' to the next
kernel, that I wouldn't be f*ck*d. But - as I just read in the new
kernel testing howto - that is a legit reason to do kernel testing ;)

I am glad to see that you found a real reason for why it might have
gone wrong. Just not initializing because it's not needed, but not
understanding WHY it went wrong would have been rather unsatisfactory.

I've tested this patch - and it works (is this the point where I'd
add an 'Ack-something'? Here is the dmesg (the -agp1 in the version
is your patch):

Hmm, the dmesg stops here... Perhaps I should have
captured it with the serial console. But well, I'll
consider it fixed I don't think there was a warning

yes, I understand, but it looks we did the wrong thing in the first step,
so... Thanks for testing this!

Looking at the above, I have no way of telling what the actual bug is, nor
have I any way of telling what the consequences would be of not having this
patch in 2.6.22.  Nor can I tell whether we want it in 2.6.21.x.

I probably _could_ work this out, and kinda did with a bit of list-trolling
(verdict: needed in 2.6.22) but please, take care to describe the
importance of a patch in the changelog?

Thanks.

This got merged a day or two ago.

"will try to access illegal regs.." being the key part of the changelog
above.  Without this diff, it goes bang, and stops booting on certain
chipsets.

OK.  -stable didn't appear to get a copy though?

Correct. It'll need a slightly different fix due to the cleanups done in .22rc
I also wanted it to sit for a few days to make sure there aren't any
other nasties lurking that this churn has unearthed.

The point is that as those host bridges only support PCIE with no AGP port, our
AGP driver shouldn't act. And by another side it can fix possible mystery problems
(like Carlo's P965) when our AGP driver does act then.
