2.6.16-mm1

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16/2.6.16-mm1/


- Added git-intelfb.patch: more fbdev drivers for Intel graphics hardware. 
  (David Airlie).

- Be aware that someone-who-doesn't-know-about-allmodconfig has screwed up
  AGP on x86_64: if your link fails with various missing AGP symbols you'll
  need to set the various CONFIG_AGP* symbols to `y' rather than `m'.  Then
  work out which other Kconfig rule keeps on flipping them back to `m' again,
  then fix that too.

  Once you've done all that, please let us know how you did it.

- John's x86 time rework patches are back again.



Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@vger.kernel.org

- If you hit a bug in -mm and it's not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.

CONFIG_SERIAL_8250=m
CONFIG_SERIAL_8250_PCI=y
CONFIG_SERIAL_8250_PNP=y

That's an illegal configuration.

+config SERIAL_8250_PCI
+       tristate "8250/16550 PCI device support" if EMBEDDED
+       depends on SERIAL_8250 && PCI
+       default y

if SERIAL_8250 is 'm' there's no way that SERIAL_8250_PCI should be 'y'.
Maybe it's a bug in kconfig - seems like it.  Let's try some experiments:

config SYM_Y
        bool
        default y

config SYM_M
        tristate
        default m

config SYM_D
        tristate 'SYM_D'
        depends on SYM_M && SYM_Y

With this I'm offered:

SYM_D (SYM_D) [N/m] (NEW)

so Kconfig thinks the only legal values for SYM_D are 'n' and 'm', and
the default is 'n'.

If I add a default line to SYM_D thusly:

config SYM_D
        tristate 'SYM_D'
        depends on SYM_M && SYM_Y
        default y

I'm now offered:

SYM_D (SYM_D) [M/n] (NEW)

Okay, so the default is now 'm', but the legal values are still only 'n'
and 'm'.  I can only select 'm' or 'n', and this is what I end up with in
the config file.  Now, if I remove the prompt text:

config SYM_D
        tristate
        depends on SYM_M && SYM_Y
        default y

and hey presto, suddenly 'y' becomes a legal value.

CONFIG_SYM_Y=y
CONFIG_SYM_M=m
CONFIG_SYM_D=y

So it would seem to be a Kconfig bug.

Thanks for explanation of the problem

Everything is ok, when I state CONFIG_SERIAL_8250=y in kernel config.

I haven't merged anything into agpgart-git for a week or two, so it's

I have some patches against -mm I use and don't seem to hurt, since long
time ago. I will try to track its origin, but I'm not sure I can :(.
Anyways I will post them here, to see if someone can tell anything.

As they are inline, this gives the compiler wide space for optmizations.

THose patches come from someone who is pretending to be davej@redhat.com ;)

We suspect the culprit is git-intelfb, which does

 config FB_INTEL
 	tristate "Intel 830M/845G/852GM/855GM/865G support (EXPERIMENTAL)"
-	depends on FB && EXPERIMENTAL && PCI && X86_32
+	depends on FB && EXPERIMENTAL && PCI && X86
 	select AGP
 	select AGP_INTEL
 	select FB_MODE_HELPERS

It's rather nasty that this can break the build.

It also seems plain wrong to me that a "select AGP" can force CONFIG_AGP=y
into CONFIG_AGP=m.  There's no sense in that.

NAK.  Its already unlikely, and if this fails, you SHOULD print 
something out.  The rest seems mostly OK.

I'm skeptical because this has caught real bugs in the past.

Unfortunately other platforms that hard-code the per-cpu
area into a cpu register, and thus implement __get_cpu_var()
without a smp_processor_id() call, don't get the debugging
check.

yes,

apparently the one that was sent to andrew and i got a confirmation for -mm is different
from whats on the broken-out patches.

I sent an email about it this mornig, havent heard from andrew yet.

Hi. :)

Hmmmm. Not sure how this would relate to the TOD bits, but they might be
somehow causing it.

Rafael, could you send me the full dmesg and .config info and I'll try
to find a box to reproduce this on?

It seems report_lost_ticks has been set to one w/ 2.6.16-mm1, thus these
debug messages will be shown.

Rafael: To properly compare, could you boot 2.6.16-rc6-mm2 w/ the
"report_lost_ticks" boot option and see if the same sort of messages do
not appear?

Yea, I think thats due to some new code from Andi.

The lost tick issue should be looked into (might be hardware SMIs), but
it seems this is not caused by my patches.

You are right.  All of this is caused by report_lost_ticks set to 1.
The appended patch helps.

Thanks,

OK, we have an andi-easter-egg:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16/2.6.16-mm1/broken-out/x86_64-mm-lost-cli-debug.patch.

So you're right, it's not the time patches.  I just blame you whenever anything
time-related goes wrong - who else is there? ;)

The above patch records the most-recent caller of local_irq_disable() in a
global variable, then prints that out in the lost-ticks handler.  But how
do we know that the global didn't get overwritten between the most-recent
local_irq_enable() and the call to handle_lost_ticks()?

I guess the code assumes that the local_irq_enable() will result in
insta-entry into the timer IRQ handler.  Which is probably good enough, as
interrupts from other sources won't be pending most times.

So why did we lose three ticks after __do_sortirq()'s local_irq_disable()? 
Dunno.

I think a better debugging patch would be:

u64 timestamp[NR_CPUS];

local_irq_disable()
{
	cli;
	timestamp[me] = rdtslcc();
}

local_irq_enable()
{
	if (rdtscll() - timestamp[me] > enough)
		whine();
	sti;
}

(Is there any point in do_softirq() doing local_irq_save() instead of
local_irq_disable()?  __do_softirq() will unconditionally enable anyway..)

I'm getting a repeatable oops regardless of io scheduler (it looks like
it's in cfq code so I first tried changing schedulers) on USB
disconnect.

Kernel is built for athlon k8, but running in 32 bit mode.  Tainted by a
madwifi driver which should have no impact on the problem area.

Oops follows, and kernel config attached.

OK, thanks.  There have been some recent changes affecting iosched context
lifetime management, which might be causing this.

If you have time, it'd be useful if you could retest with
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.16-git6.gz -
that'll tell us whether it's that code or if it's something which is only
in -mm.

Unable to reproduce with identical steps on git6.  Thanks for the

ok..

I tried various combinations of plugging, mounting, unmounting and
unplugging a USB memory stick.  No problems.

Can you prepare a step-by-step guide to making this happen?

Thanks.

Re: 2.6.16-mm1

[Brandon Low]

I hadn't noticed immediately in the ooops, but it is something to do
with the Hardware Abstraction Layer Daemon from http://freedesktop.org/Software/hal
I can't reproduce it without that daemon loaded either.  I wonder if the
last accessed sysfs file mentioned in the oops (sda/size) is relevent
also.

My exact steps (with hald loaded) are:
plug in ipod
mount /mnt/ipod
unzip -d /mnt/ipod rockbox.zip
eject /dev/sda
unplug ipod
immediately here, the oops prints.

Interestingly after this happens, the system remains at a pretty high
level of functioning, and further mounts and unmounts and ejects of the
ipod do not cause another oops.

Because the overdue timer interrupt will trigger one instruction later.

Yes. Actually irq 0 has higher priority than most interrupts,
but not all.

It's a mistery. I put the patches in to trace a pattern.

But you're right they should at least be using per cpu variables
instead of globals which can be corrupted by other CPUs.

The interrupt handling in there is quite messy and has some other
wards too. Could probably take a good cleanup. Problem is that
it will need a lot of editing of architectures to do properly.

No, it's not a bug, that's really the correct behaviour. It has its roots 
in the cml1 converter, where statements like this:

if [ "$CONFIG_FOO" = "y" ]; then
  define_tristate CONFIG_BAR y
fi

would become:

config BAR
	default y
	depends on FOO=y

The basic idea is that the dependency only enables the default and the 
default sets the symbol to whatever you want.

I thought about the other behaviour, but at that time the if syntax or 
select didn't exists yet, so it really wasn't a problem yet and I decided 
to keep it closer to cml1 instead.

In the meantime the Kconfig syntax has grown and this is not the first 
time this has come up. I'm not completely opposed against changing the 
behaviour, but I don't want to do it just for fun either. It would require 
at least to grep through the current Kconfig rules to check whether 
something depends on the current behaviour.

As alternative you can change the default to "SYM_M" (basically repeating 
the dependency without the booleans).

Still no joy, alas.

git-cfq.patch plays with the elevator exit code for all IO schedulers. 
Would you be able to do

wget ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16/2.6.16-mm1/broken-out/git-cfq.patch
patch -p1 -R < git-cfq.patch

and retest?

Thanks.

2.6.16-mm1 grub oddness

[Mike Galbraith]

Greetings,

I'm seeing strange things with grub with this kernel.  After my box has
been up for a while, and I reboot, selecting a kernel to restart, upon
reboot, I sometimes (fairly often) get a blank screen staring at me
though I see grub doing it's thing.  Poking the power button results in
an immediate poweroff, not as if the kernel had panicked or whatnot very
early in boot.  Very odd, and never before seen.

(I was worried that my scheduler stuff was causing weird interactions,
but after testing, it's not me, it's there in virgin source.)

	-Mike

select and default don't really mix very well, a default is only active if 
nothing else enables the symbol, but select already enables here AGP, so 
the AGP default isn't needed/used anymore.
It's somewhat related to the other default behaviour, without changing 
that I don't see a clean and simple way to change this right now.
The easiest solution is to simply remove the default and let GART_IOMMU 
select AGP too.

bye, Roman




The AGP default doesn't work well with other selects, so use a select for 
GART_IOMMU as well. Remove a redundant default for SWIOTLB as well.

GART_IOMMU works without AGP driver too. It just has the requirement
that the AMD64 AGP driver is either builtin or not enabled at all.

I don't see how this is/was possible, if GART_IOMMU was enabled so was AGP 
(and AGP_AMD64). That hasn't changed with the patch.

That was/is a bug that was originally introduced in the 2.4->2.6 Kconfig conversion.
The code was designed to handle it and did in 2.4.

It is definitely this patch.  Identical steps (also used an untainted
kernel for both tests) on -mm1 with and without that patch, and when the
patch is reversed, I cannot cause the oops.  I booted into single user
mode (to dodge tainting and any other weirdness), started the dbus
system message daemon and hald (which depends on dbus), then performed
the steps mentioned above.

Thanks!

It's debatable whether it's really a bug in the conversion.

2.4 does this:

if [ "$CONFIG_GART_IOMMU" = "y" ]; then
   bool '/dev/agpgart (AGP Support)' CONFIG_AGP
else
   tristate '/dev/agpgart (AGP Support)' CONFIG_AGP
fi

Dynamically changing the symbol type isn't supported anymore and it works 
in 2.4 only by accident (e.g. it breaks the old xconfig).

If we really want to do something like this we had to introduce two 
different symbols. Something like:

config GART_IOMMU
	....

config AGP_BOOL
	bool "builtin AGP support"
	depends on GART_IOMMU
	select AGP
	select AGP_AMD64
	help
	  Our IOMMU code sucks. :-)

We could also just remove the select/default and add a comment after 
AGP_AMD64 depending on "AGP && GART_IOMMU && AGP_AMD64=m" saying that this 
configuration disables IOMMU support for it and be done with it.
Another alternative is to fix the code to reinitialize the iommu stuff 
when agp module is loaded.

Do you mean that grub is actually proceeding as expected, just that the
display is off?  If so, does it ever come back on?

Would it be reasonable to guess that some piece of code on the reboot path
is now poking the display hardware in a manner which shuts it off?

Are you using an fbdev driver?  If so, which?

Okay, so going to the exact problem case, the behaviour we require is:

SERIAL_8250	PCI	EMBEDDED	gives SERIAL_8250_PCI
	n	X	X		n
	X	n	X		n
	m	y	n		m
	y	y	n		y
	m	y	y		user selects 'm' or 'n'
	y	y	y		user selects 'y', 'm' or 'n'

the correct way to tell Kconfig to give us that is:

+config SERIAL_8250_PCI
+       tristate "8250/16550 PCI device support" if EMBEDDED
+       depends on SERIAL_8250 && PCI
+       default SERIAL_8250
+       help
+         This builds standard PCI serial support. You may be able to
+         disable this feature if you only need legacy serial support.
+         Saves about 9K.

No dice, I just had another dead reboot.  Nobody else seems to be seeing
this, so maybe my box is going south.  A single bit error the other day,
and now this.  Maybe it's not the kernel, just a coincidence that I've
only seen it with 2.6.16-mm1.  Maybe I've got dust crawling into memory
sockets or whatnot.  Memtest86 time.

It's apparently not my hardware btw.  If I find out what it is that's
causing this, I'll holler.

[-mm patch] BLK_DEV_IO_TRACE Kconfig fixes

BLK_DEV_IO_TRACE breaks the rule "If you select something, you must 
endure that the dependencies of what you are select'ing are fulfilled."
resulting in the following compile error with CONFIG_SYSFS=n:

<--  snip  -->

...
  LD      .tmp_vmlinux1
fs/built-in.o: In function `debugfs_init':inode.c:(.init.text+0x3d35): 
undefined reference to `kernel_subsys'
make: *** [.tmp_vmlinux1] Error 1

<--  snip  -->

This patch fixes this bug.

Additionally, it moves the BLK_DEV_IO_TRACE option that now depends on 
DEBUG_KERNEL into the menu with the other DEBUG_KERNEL options.

Thanks for the sysfs fix, however don't move the kconfig entry, this
isn't a debug option.

It select's an option depending on DEBUG_KERNEL, and therefore also has 
to depend on DEBUG_KERNEL.

IMHO that should be removed, debugfs should be generally available. At
least with blktrace, it's not necessarily a debug feature.

The tentative winner for my reboot (and boot) problems appears to be
frequency scaling changes between 2.6.16-rc6-mm2, which worked fine,
and 2.6.16-mm1.  Disabling frequency scaling appears to fix my troubles.
Caveat emptor: intermittent.

(Difficult for me to believe that having this compiled in could do a
number on my p4.  Reverting the hotplug thingie gave me suspend back and
nothing more [as expected].  Color me befuddled.)

Hmm, no luck reproducing this so far, strange. I'm using
2.6.16-block.git cfq branch exclusively, which is the patch you backed
out. I guess I'll try 2.6.16-mm1 on the same box next.

Can you try 2.6.16-mm1 with this patch applied on top?

I've got a same oops in 2.6.16-mm1, and this patch seems to fix it at
least in my case.

Super, it should fix it afaict, but not being able to reproduce I could
not say for sure. Thanks very much for testing and reporting back.

what is the purpose of this patch?  what bug is it solving?  Are we
trying to achieve some goal?  A comment at the very least is
necessary.  I don't like changing timing stuff unless we have some
clear reason.  In fact I sent a patch a while back to a guy who was
complaining about latency in a -RT kernel with e100 and he said this
kind of change made things worse: see the end of:

http://marc.theaimsgroup.com/?l=linux-kernel&m=113808831932769&w=2

The problem in this case is the mii library calling back into our
mdio_read.  eepro100's mdio read hard spins with no delay besides the
ioread32 delay created by reading from an i/o port.  This could
explain the glitching in an RT kernel.

Is this the kind of problem this patch tries to solve?

Thanks,
  Jesse
