"Read my lips: no more merges" - aka Linux 2.6.14-rc1

[Linus Torvalds]

Ok, it's been two weeks (actually, two weeks and one day) since 2.6.13, 
and that means that the merge window is closed. I've released a 
2.6.14-rc1, and we're now all supposed to help just clean up and fix 
everything, and aim for a really solid 2.6.14 release.

Both the diffstat and the shortlog are so big that I can't post them on 
the kernel mailing list without getting the email killed by the size 
restrictions, so there's not a lot to say. 

alpha, arm, x86, x86-64, ppc, ia64, mips, sparc, um.. Pretty much every
architecture got some updates. And an absolutely _huge_ ACPI diff, largely 
because of some re-indentation.

drm, watchdog, hwmon, i2c, infiniband, input layer, md, dvb, v4l, network,
pci, pcmcia, scsi, usb and sound driver updates. People may appreciate
that the most common wireless network drivers got merged - centrino
support is now in the standard kernel.

On the filesystem level, FUSE got merged, and ntfs and xfs got updated. In 
the core VFS layer, the "struct files" thing is now handled with RCU and 
has less expensive locking.

And networking changes.

In other words, a lot of stuff all over the place. Be nice now, and follow 
the rules: put away the new toys, and instead work on making sure the 
stuff that got merged is all solid. Ok?

Anybody with git can do the shortlog with

	git-rev-list --no-merges --pretty=short v2.6.14-rc1 ^v2.6.13 |
		git-shortlog | less -S

which is actually pretty informative.

Kudos for merging IPW in.

I have these 2 "commands" I Run to get the latest git.
debian:~# cat getkernel
#! /bin/bash
git clone
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
linux-2.6
cd linux-2.6
rsync -a --verbose --stats --progress \
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/ \
.git/

getkernel was the first I used to get the whole thing and only used it
once.

debian:~# cat getkernelupdate
#! /bin/bash
cd linux-2.6
git pull
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
git checkout


I use getkernelupdate to "download the updated git with the new patches
sent.

If I do make menuconfig, it still says 2.6.13 instead of 2.6.14-rc1.

Do I have something missing?

I do git commit and git checkout after those scripts above.

Any answers are appreciated!!

Hi,

	Is Linus git tree the one used for the rc's and the final release?

I keep updating and it still says 2.6.13 instead of 2.6.14-rc1. I don't
really care if that is cosmetic, is fine, I just want to make sure that
I'm up to date?

Again, this is what I do:

cd linux-2.6
git pull
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
git checkout

? Anyone

PS: Thanks for kicking in HDAPS into this tree.

I don't know. How can I tell? I did run those commands, which BTW are from
your How-To.

I think it is up to date, but it still doesn't say 2.6.14-rc1. That's the
only confusing part.

What does "git log" state? Do you have recent state there? (ie it should 
have dates in the "Sep 12" kind of timeframe)

Also, if you have done something earlier that updated your HEAD file
_without_ actually updating your checked out status, then "git checkout" 
may decide that it has nothing to do. You can try "git checkout -f" in 
that case.

Linus,

	Thanks for the reply. I'm almost sure I did all the above following Jeff's
document.

I will do it again to make sure. Additionaly, thanks for the git log tip. I
didn't know how to check how new the git tree was.

Linus,

	Thanks for the tip. git checkout -f did it. I dunno but I always run
it, anyway, it worked now that you mentioned it. ;-)

Additionally,

debian:~# cd linux-2.6/
debian:~/linux-2.6# git log
/usr/local/bin/git-log-script: line 4: less: command not found

Anyway! I can see how it is updated now.

Thanks!

I suspect that you were just hit by the kernel.org mirroring delay. The 
change to the Makefile is the very last thing I do before a release, so 
if the mirrors are slow, you won't get that change for about half an hour 
or so..

I hope this means that people will be more accepting of multi-threaded
benchmarks (who needs real apps... ;-)) which do open() and close().


Yes, no?

If you look at RCU change, you discover they impact read()/write()/... (no 
more locking), but not open()/dup()/socket() and close() that still take a 
spinlock to modify the state.

And if your process has many files opened, the cost (read : latency) of open() 
can be very high, finding a zero bit in a large bit array.

So these RCU changes can help some benchmarks (or real apps... ;-) ), but not 
some others :)

I wish a process param could allow open() to take any free fd available, not 
the lowest one. One can always use fcntl(fd, F_DUPFD, slot) to move a fd on a 
specific high slot and always keep the 64 first fd slots free to speedup the 
kernel part at open()/dup()/socket() time.

Why not just remember the lowest available free slot and start each
bitmap search there?  This is a quite common technique.

Ehh. That's what "files->next_fd" is (well, now it's in the fdt
structure).

The overhead is easy to avoid by making use of dup2() and close() to keep 
the lowest file descriptors in the table free, allowing open() and socket() 
to always return 3 or 4.

Alternatively, the kernel could track available file descriptors using a 
tree to efficiently insert freed slots into an ordered list of free 
regions (something similar to the avl tree used in vmas).  Is it worth 
doing?

For file descriptors, even a few hundred is considered a _lot_ in almost 
all settings. Yes, you can certainly have more, but it's unusual.

And we keep track of the fd reservations with a bitmap _and_ a "lowest
possible" count. So we can check 32 fd's in one go (64 on modern setups),
starting from the last one we allocated.

In other words, no. It's not worth doing anything more than we already do. 

I bet all the expense in this area tends under heavy load to be the
cacheline bouncing of the updates. Keeping the lock close to the bitmap is 
probably advantageous, since the bitmap tends to be looked at only when we 
need to change them (and we hold the lock).

Absolutely :)

Here is the patch I use to :

- place modified bits (file_lock & next_fd) in a separate cache line, reducing 
cacheline bouncing for multi threaded apps.
- Reduce the size of struct (files_struct), using small embedded fd_sets 
matching fd_array[NR_OPEN_DEFAULT] (ie one long per 'fd_set' instead of 128 bytes)
- 10 % gain on a benchmark ran on a dual HT Xeon 2GHz, one thread per logical CPU.

Yes, this is what I described :) Maybe this was not clear.

Well no, since a user app can manage itself this part if it happens to be 
performance critical.


Sample of a user land lib : Each time a new fd is returned by 
open()/socket()/pipe()/accept()... the thread should call

fd = fdcache_dupfd(fd);

And close the file using  fdcache_closefd(fd) instead of close(fd);

I'm getting a linker error due to disable_timer_pin_1, which is defined in
io_apic.c as int disable_timer_pin_1 __initdata;

but I'm building with

CONFIG_X86_UP_APIC=y
# CONFIG_X86_UP_IOAPIC is not set
CONFIG_X86_LOCAL_APIC=y

The error is in setup.c, which can't find the variable since io_apic.c isn't
being compiled in.

Sorry to bother you again and again with this stuff, but I got no answer
from anyone... DVD burning is broken since 2.6.13-rc1 and I checked this
morning the 2.6.14-rc1: Same status.

To be short, when burning a DVD at 16x with 2.6.12.6, no problem at all.
With 2.6.13-rc1 and upper, lots of buffer underruns. (If someone wants
to help, feel free to ask more details... I would be happy to help
anyone). The only thing that I know is that it is not coming from the
peripheral driver, as I have the same issue when using ide-cd with a
CDROM_SEND_PACKET ioctl or usb-storage+sg with a SG_IO ioctl.

As far as I looked in the source code, it seems to be lots (and lots) of
changes between these 2 versions, specially regarding block devices
drivers. But the ChangeLog is so huge that it is quite impossible to
make a step-by-step upgrade to see _where_ the problem is :-(

You can do a bisection search with git, that will pinpoint exactly
which patch that cause trouble.  It is much easier to get a
maintainer to fix it if you can point the finger at one particular patch.

The recipe for bisection search is in the mailing list archives,
or send me an email, I've done it once.

Yes, 2.6.12..2.6.13-rc1 was pretty big, However, the IDE driver changes 
aren't that big.

None of your bug-reports seem to say even what driver you're using, 
though, so it's a bit hard to make any judgement at all.

We at a minimum need to know what driver, and see boot messages (both
working and nonworking), and preferably things like "hdparm -I" output 
(again, both working and nonworking) too. Often "lspci -vvx" is useful 
too.

So I would say that it is related to somehow some kind of timeout in
SCSI I/O (but really not sure...). As far as I saw, there is now an
option in the kernel config file related to this, so I will try to see
what happens with 1000 Hz and 100 Hz (I left the default value of 250 Hz
for my tests).

Many thanks to all that helped ;-)

Thanks, interesting.

And hey, 13 compilations may sound like a lot, but considering that there
were 2069 commits between 2.6.12 and 2.6.13-rc1, having to do "just" 13
kernels to pinpoint the exact cause is pretty good, I think.

Interesting, and a bit scary. If it worked with 1kHz (old default value),
it's not even any of the old Linux x86 timeouts (that were designed for
100 Hz), so it's some _new_ HZ dependency.

Yes, that would be interesting.

Btw, what's the exact error message you get? (And is it the kernel or the
burning app that complains?)

Yes I know. I was just kidding ;-) I would say that I didn't know the

Okay, here is the point: I will have these bloody buffer underruns
unless I select a 'Timer frequency' of 1000 Hz in 'Processor type and
features' section of the kernel configuration. That's quite
understandable, as recording a DVD at 16x requires a throughput of 22160
KB/s, which is quite fast.

I will have a deep look in the patch, and maybe write a patched patch
(Ooooo my god what am I writing ?) in the next few days.

I do not get any kernel error message. It is just my burning app that
complains that buffer underruns occured, as if the source media was not
fast enough to deliver 22160 KB/s.

It may just be an application bug too. Too small a buffer, and depending 
on 2.6.x with a 1kHz timer having timers that run faster...

According to the MMC documentation, you can thoeriticaly send at most
65535 (16 bits int) blocks in one WRITE(10) CDB. This would means
sending a buffer of ~127 MB on case of writing a mode 1 data track (2048
bytes per block)...

Now, practically, it is really not safe to send more than 64 KB per CDB
(Mostly device related). And with such values, you have the following:
 - at 100 Hz  -> 64 KB * 100  = 6400 KB/s  <=> ~4.62x  DVD 
 - at 250 Hz  -> 64 KB * 250  = 16000 KB/s <=> ~11.55x DVD 
 - at 1000 Hz -> 64 KB * 1000 = 64000 KB/s <=> ~46.20x DVD

I would suggest to leave to default value of the timer frequency to 1000
Hz and to add some more comment in the Kconfig.hz file. (Patch attached)

But that implies that there's some piece of code somewhere (could be
userspace, could be kernel) which is doing a timer-based sleep() in between
each CDB.  It shouldn't do that - it should be using the disk
controller's completion interrupt for synchronisation.

What userspace application are you using to write the DVDs, and is it
possible to test a different one?

Hummm... you are definitly right. So forget my calculations. I does not
mean anything. Honestly, I was just trying to find an explanation why it
was working with HZ set to 1000 and not with HZ set to 250 or 100.

> What userspace application are you using to write the DVDs, and is it

I am using NeroLINUX to make my tests. I also tried out
cdrecord/growisofs, but I was not even able to burn at 16x (I get some
error message that max speed is 10x... and nothing more).

But there seems to be somehow some I/O limitation: I configured a pure
2.6.13.1 to have HZ set to 100. I then made a 3 GB compilation with
small files (about 3 to 5 MB each).
 - If you burn this directly without creating a temp ISO image in 4x
(5440 KB/s), you will get buffer underruns soon or later... (about 2%)
 - If you create an ISO image out of the compilation (using mkisofs or
other tool), and then burn this image, then no buffer underruns occurs.

After that, you speed up your recorder with this image (for example at
8x), you will have these buffer underruns back again.
And as I tell you, no such stuff is happening when HZ is set to 1000.

OK, so you get underruns with NeroLINUX at 8x, and it should be possible to
test cdrecord at 8x, yes?  If that works then it's time to take a look at
what NeroLINUX is doing..

erp, it's payware.   strace, maybe?

Data point... recent 2.6.13 (possibly after 2.6.13-final) allow
 my puny K7-800 256MB RAM to burn DVDs with growisofs
 at 8x, whereas earlier releases would peak at 8x then step
 back to 4x. Currently burn starts at 5x and goes up steadily
 to 8x in a couple of minutes, then stays there until the DVD
 is done. I never tested 16x - actually I haven't yet owned a
 16x capable DVD disc... but I doubt my system could burn
 that fast - 8x is already a blessing ;)

With cdrecord I can set the FIFO buffer size up to 20MB or so, which is 
locked in memory when running as root. The issue seems to be moving the 
data from the application buffer to the device buffer. Something in the 
kernel would appear to only do that data transfer on a timer tick. It 
may be that the dispatch latency is just too high, and that the thread 
pushing the data to the device is just not getting the CPU in time, even 
with the application buffer locked and the application running at RT 
priority.

I generally build my kernels with voluntary preempt, I think I tried a 
real preempt kernel without improvement, but I can't swear to it. If the 
O.P. doesn't mind a 14th build that might be a decent data point.

i dont have an example dmesg error message now, but there is nothing to
it, its just a standard, hda input/output error..

one thing though, with kernels <2.6.13 i am able to simply cancel, and
burn again, with >2.6.13-rc* it freezes completely, and i gotta reboot
before i can get the dvd out.

i use the via ide driver in the kernel.

another thing, it happens at ~95-99% of the burning process in nearly
all cases, with one exception of half way through, and one case where it
was like 70%.

i hope this can help.

Re: "Read my lips: no more merges" - aka Linux 2.6.14-rc1

[Roland Dreier]

Sorry for being dense, but can you say what "no more merges" means?

At the kernel summit we talked about no more git merges after the
initial devel period, and I'm wondering if that really is the policy.

As a concrete example, suppose I have a git tree with something like

 drivers/infiniband/hw/mthca/mthca_qp.c    |    2 +-
 drivers/infiniband/ulp/ipoib/ipoib_main.c |    2 ++
 2 files changed, 3 insertions(+), 1 deletion(-)

ie a couple of really small, simple fixes.  Emailing those to Andrew
as patches is fine by me, but it seems like it creates extra work for
Andrew and you.  So is email via Andrew what you want, or are "bugfix
only" git pulls OK?

Thanks,
  Roland

It's not so much a technical thing - I'll happily do git merges that fix 
bugs. But I don't want to merge big stuff (of course, it turns out that 
I'd missed a few before the release, so I did those anyway).

I'll happily take them. I'd suggest you include the patches themselves in 
the "please pull.." message, just to make it obvious what's going on, but 
it would be stupid to avoid using technical means to get the patches in. 
So I'll certainly go git merges for these kinds of things.

[Horst von Brand]

After the big "no more merges" push of stuff into 2.6.14-rc1 on i686 I get:

   arch/i386/kernel/built-in.o: In function `parse_cmdline_early':
   : undefined reference to `disable_timer_pin_1'
   arch/i386/kernel/built-in.o: In function `parse_cmdline_early':
   : undefined reference to `disable_timer_pin_1'
   arch/i386/kernel/built-in.o: In function `parse_cmdline_early':
   : undefined reference to `disable_timer_pin_1'

In io_apic.c there is an:

   int disable_timer_pin_1 __initdata;

but that file isn't compiled here, as CONFIG_X86_IO_APIC isn't set; while
the pieces that reference this are protected by CONFIG_X86_LOCAL_APIC. An
option changed name, perhaps?

My AMD64-based box (Asus L5D) does not resume from disk on battery power
any more, even if booted with init=/bin/bash.

I think this is related to Bug #4959, which remains a mistery, but now it
also does not resume with CONFIG_DEBUG_SLAB unset.

Andi, is it possible that an MCE occurs when the image is copied (ie. while
the code in arch/x86_64/kernel/suspend_asm.S is being executed)?

Greetings,
Rafael

Was there some problems with the current version of the ipw2200 driver 
(1.0.6) which required using the 1.0.0 version from several years ago?

And is the Centrino "modem" now working? Or just the wireless?

Good to see all this work, but I suspect it will be a long debug cycle 
as people shake it out. I will probably build it tonight, try it tomorrow.

There is no Centrino modem, as such. Vendors can put a variety of codecs
on the board. Most of them are supported with the snd-intel8x0m driver
and the (closed) slmodem userspace binary, but Conexant ones (as used by
IBM) require binary drivers from Linuxant.

I can bore the list with a config, but this seems pretty common over x86 
configs, similar happened on desktop (this one), laptop, and server builds.

Ah, I see it, config needs to note that IOAPIC is now required. That's 
probably not desirable, there are systems with broken ioapic which 
should not be used.

My cardbus is acting funny. When I insert my netgear wg511 (prism54) the 
first time after booting 2.6.14-rc1 nothing happens. Nothing in dmesg, 
nothing nowhere. I remove it. Still nothing. Oh well. Inserting again. 
THEN it initializes and is working like it usually does.

2.6.13+Ivan's PCI resource patch worked allright.

I can live with this, but this is a regression.. I remember having 
exactly the same problem with some 2.4 kernel a few years back..

Any patch I should try backing out? Or some patch I should try?

Somebody who's familliar with the code (as opposed to me) might be
able to point to a specific patch, but you could also try doing a
bisection search with  git bisect  to try and find the patch between
2.6.13 and 2.6.14-rc1 that broke it for you. A few handfuls of kernel
compiles/boots usually does the trick.
Search the archives for details, it's been described numerous times.

Whops. I lied. 2.6.13+Ivan's patch behaves just the same.. Too bad I 
didn't test that BEFORE I bisected and recompiled the kernel 12 times. ;/

So..I guess this has something to do with the PCI update in 2.6.13.. Any 
pointers to where I should start bisecting this time?

2.6.14-rc1 on ATI hangs when executing _STA and _INI methods

My Compaq Presario R3057EA hangs during ACPI initialization. The last
message is "Executing all Device _STA and _INI methods". git bisect
told me that:

    Original patch from Bertro Simul

    This is probably still not quite correct, but seems to be
    the best solution so far.

Passing enable_timer_pin_1 as a kernel boot parameter doesn't help,
but this patch does:

 			return;
 		}
 		clear_IO_APIC_pin(0, pin1);

But doing that is equivalent to reverting the whole patch, so it's
probably not the right solution. My computer has an Intel P4 CPU, ie
it's not x86_64.

Ok. That patch has been one big pain, and was clearly totally half-baked.  
I think I'll disable the automated checks, since they are clearly wrong.
You can still enable it manually with a kernel command line.

So something like this.. I assume this works for you?
