- The CPU scheduler changes in -mm (sched-domains) have been hanging about
  for too long.  I had been hoping that the people who care about SMT and
  NUMA performance would have some results by now but all seems to be silent.

  I do not wish to merge these up until the big-iron guys can say that they
  suit their requirements, with a reasonable expectation that we will not
  need to churn this code later in the 2.6 series.

  So.  If you have been testing, please speak up.  If you have not been
  testing, please do so.


- Major surgery against the pagecache, radix-tree and writeback code.  This
  work is to address the O_DIRECT-vs-buffered data exposure horrors which
  we've been struggling with for months.

  As a side-effect, 32 bytes are saved from struct inode and eight bytes
  are removed from struct page.

  This change will break any arch code which is using page->list and will
  also break any arch code which is using page->lru of memory which was
  obtained from slab.

  It seems to work OK here, but I suggest people not rush out and convert
  all of the corporate finance department's servers to 2.6.4-mm1.

  The basic problem which we (mainly Daniel McNeil) have been struggling
  with is in getting a really reliable fsync() across the page lists while
  other processes are performing writeback against the same file.  It's like
  juggling four bars of wet soap with your eyes shut while someone is
  whacking you with a baseball bat.  Daniel pretty much has the problem
  plugged but I suspect that's just because we don't have testcases to
  trigger the remaining problems.  The complexity and additional locking
  which those patches add is worrisome.

  So the approach taken here is to remove the page lists altogether and
  replace the list-based writeback and wait operations with in-order
  radix-tree walks.

  The radix-tree code has been enhanced to support "tagging" of pages, for
  later searches for pages which have a particular tag set.  This means that
  we can ask the radix tree code "find me the next 16 dirty pages starting at
  pagecache index N" and it will do that in O(log64(N)) time.

  This affects I/O scheduling potentially quite significantly.  It is no
  longer the case that the kernel will submit pages for I/O in the order in
  which the application dirtied them.  We instead submit them in file-offset
  order all the time.

  This is likely to be advantageous when applications are seeking all over
  a large file randomly writing small amounts of data.  I haven't performed
  much benchmarking, but tiobench random write throughput seems to be
  increased by 30%.  Other tests appear to be unaltered.  dbench may have got
  10-20% quicker, but it's variable.

  There is one large file which everyone seeks all over randomly writing
  small amounts of data: the blockdev mapping which caches filesystem
  metadata.  The kernel's IO submission patterns for this are now ideal.


  Because writeback and wait-for-writeback use a tree walk instead of a
  list walk they are no longer livelockable.  This probably means that we no
  longer need to hold i_sem across O_SYNC writes and perhaps fsync() and
  fdatasync().  This may be beneficial for databases: multiple processes
  writing and syncing different parts of the same file at the same time can
  now all submit and wait upon writes to just their own little bit of the
  file, so we can get a lot more data into the queues.

  It is trivial to implement a part-file-fdatasync() as well, so
  applications can say "sync the file from byte N to byte M", and multiple
  applications can do this concurrently.  This is easy for ext2 filesystems,
  but probably needs lots of work for data-journalled filesystems and XFS and
  it probably doesn't offer much benefit over an i_semless O_SYNC write.

- Dropped the hotplug CPU patches: bits of them were merged into Linus's
  kernel and things broke.

- Various little fixes as usual.

Looks extremely kick ass! mpage is has a left-over spin_unlock in there
though, I need this to boot:

I have that process automated rather well now. If anybody wants the import

Hi,

on my config (opteron box) I need this patch to get it compiled :

                return 1;
        return 0;
 }

I guess it's been forgotten in some other patch. (and i hope it's the good fix :)

while I am at it, I am running a 64 bits kernel with 32 bits debian testing and
it seems some ioctl conversion fails
that happened with all 2.6 I tried.
here is the relevant kernel messages part :
ioctl32(dmsetup:26199): Unknown cmd fd(3) cmd(c134fd00){01} arg(0804c0b0) on /dev/mapper/control
ioctl32(fsck.reiserfs:201): Unknown cmd fd(4) cmd(80081272){00} arg(ffffdab8) on /dev/ide/host0/bus0/target0/lun0/part4

Cheers,
Mik

The device mapper version 1 ioctl interface was removed.  Perhaps you need
to update your dm tools?

> ioctl32(fsck.reiserfs:201): Unknown cmd fd(4) cmd(80081272){00} arg(ffffdab8) on /dev/ide/host0/bus0/target0/lun0/part4

Is this something which 2.6 has always done, or is it new behaviour?

reiserfs ioctl translation appears to be incomplete...

Some clown is running around "fixing" our ioctls:

X0081272 is BLKGETSIZE64. Yeah its bust, it was one of those calls that
we passed in sizeof(8) instead of 8. The ioctl should be X0041272. 
The definition is:

#define BLKGETSIZE64 _IOR(0x12,114,size_t)

However at least in debian unstable, util-linux has:

./fdisk/common.h:#define BLKGETSIZE64 _IOR(0x12,114,8)  /* 8 = sizeof(u64) */
./lib/get_blocks.c:#define BLKGETSIZE64 _IOR(0x12,114,long long)

ie X0081272

the debian tools are built with ioctlv4 (and compat for v1)
I also tried with my own compiled dm tools from source without success

Hi Andrew,
    I have a feeling this change might significantly improve the external
sorting benchmark I emailed you ( http://lkml.org/lkml/2003/12/20/46 ).
I will try running it when I get a chance and let you know.  It gives me
a good excuse to get 2.6 kernels working on my systems :-)

Thanks,

Jim

Hmm, what is happening with Roger Luethi's work lately?

Have there been any patches for use once in this case?

That thing's still sitting in by Inbox awaiting attention :(

I just took a quick peek.  The `testfile' file which it lays out is well
laid-out so yes, if you're seeking all over that file then 2.6.4-mm1 may
indeed help throughput.

But `tesfile.tmp' is not well laid-out.  Looks like it was created seekily,
so its blocks are all jumbled up.

The code in 2.6.4-mm1 favours unjumbled-up files.  The code in 2.4 and
2.6.4 favours jumbled-up files.

When kjournald performs writeback it favours jumbled-up files, even in
2.6.4-mm1.

So it's hard to say what will happen ;)  I'll take a look later.

I sucked sched-* out of mm, added sched-ppc64bits (attached) and am
having problems with the following threaded test case. NUMA is enabled.

#include <pthread.h>
#define NR_THREADS 100

void dostuff(void *junk)
{
        while(1)
                ;
}

int main()
{
        int i;
        pthread_t tid;

        for (i = 0; i < NR_THREADS-1; i++)
                pthread_create(&tid, NULL, dostuff, NULL);

        dostuff(NULL);
}

100 runnable threads but we never use more than one cpu:

          user    system idle                     user    system idle

OK thanks. This is probably a simple bug somewhere. I'll have a look

Hi Anton,
You need to be setting cpu_power for each of the CPU groups.

Aha, thanks. I'll do that and retest.

Thanks Nick, that fixed it. New patch attached, its basically the x86
version with cpumask fixes when compiling with NR_CPUS > 64.

hey andrew, i have a problem with this kernel, when it boots, it lists
vp_ide and stuff, and then suddenly after that my screen gets flodded
with sys traces and stuff, i cant even read it, so fast they come, and
the syste doesnet go further, i havent tried 2.6.4 vanilla yet, but i
will now.

if u got any ideas, please tell me, and i will test

Did you remove the spin_unlock_irq() from the end of mpage_writepages()?

Re: 2.6.4-mm1

[Redeeman]

i didnt do anything more than patch with mm1, is there a patch for doing
that spin_unlock_irq()? :)

Re: 2.6.4-mm1

[Redeeman]

yeah andrew it works! you are god!!
while i got you here, i have got a pray more for you.

its about amd64-agp. i never had it working (from 2.6.1 mm and vanilla)
but in 2.6.4-rc1-mm2 it worked! but sadly abit unstable :(

my big problem is that when using X, and having some windows opens, it
consumes ALL cpu if amd64-agp isnt in kernel, so i would REALLY
apreciate if you could look at it (sorry my bad english)

thanks!

I'm having similar problems, with the kernel crashing with not syncing
in interrupt error after a lot of oopses and BUGs. I'm trying to find
which patch is causing this, since 2.6.4-rc2-mm1 and 2.6.4 work fine.

I'll post my findings, when they are ready.

  Yes, the patch is right... I tested modular filesystem but forgot
about modular quota formats ;(.

Sorry, that could not work. This patch reverts my changes to loadable
device drivers. As Arjan van de Ven already noted, they have to
be converted to request_firmware() anyway.

rude changelog.  Is that inadequate?

The symbols are already exported on alpha, arm, parisc, um and x86_64,
but I'd rather not have them available to modules at all in order to
prevent driver writers from (ab)using them after KERNEL_SYSCALLS have been
eliminated.

But then the removal of KERNEL_SYSCALLS becomes hostage to those drivers,
and nobody is working on them.   It'll never happen.

The DVB folks claimed to be working on fixing this up a few weeks back,
still not seen any patches though.

Which drivers can be considered to be good examples for the firmware 
framework ?

These are working drivers, and it's a stable kernel series...

for some value of working... 
I mean, I'm not convinced the code is actually secure
(what if the fd they use is shared via a thread and userland is mucking
about with that fd to do funky stuff ???)

Re: 2.6.4-mm1

[Neil Brown]

2.6.4-mm1 doesn't work for me :-(

I get the:
   Uncompressing kernel ... now booting Linux

message, and then ...... nothing.

I've seen this before when trying to boot a P4 kernel on a P-classic
etc, so I tried compiling with CONFIG_M386, and got lots of compile
errors:

include/asm/acpi.h: In function `__acpi_acquire_global_lock':
include/asm/acpi.h:74: warning: implicit declaration of function `cmpxchg'

So I tried the default (CONFIG_M686) and it still doesn't work.

So: where do I look next?

I've included some of the machine specs below together with a config
file.

Thanks.

(I did include the mpage.c fix)

Tried adding earlyprintk=vga?

If that works, judicious addition of printks will narrow it down.

It doesn't.

I've tried compiling with SMP - no go.
I've tried with gcc-2.95 (instead of 3.3.2).  Still no go.

I thought I might try selectively removing patches, but it isn't clear
what order the borken-out patches were applied it.
If you have an ordered list, I can try a binary search.
Or if you can suggest some patches that I can try backing out....

Your .config works happily here.

See the `series' file in the broken-out directory.

Maybe turn off -mregparm?  Or back off the 4g/4g patches?  Maybe they broke
non-4:4 code comehow.

Ahh... would you consider moving that up one level, or spelling it
"Series" or "00series" or something to make it stand out for the
uninitiated??

Looks like it might be a good guess....

I cannot reach the reset button on the weekend, so I wrote a little
boot-time script which would apply the next patch, mail me, recompile,
install, and reboot.

It got up to stop-using-dirty-pages.patch and died because of the
spin_unlock in mm/page.c - I left SPINLOCK_DEBUG configured :-(

But that only leaves

   257  ppc-fixes.patch

of which, the 4g and the 4k-stack patches look most likely.
I'll finish the hunt when I get back to the office.

And it turns out it was spot on.
Applying  4g-2.6.0-test2-mm2-A5.patch (on top of preceding -mm1
patches) causes my server not to boot.

I tried all the broken out patches except
     4g-2.6.0-test2-mm2-A5.patch
     4g4g-locked-userspace-copy.patch

but then it couldn't find /sbin/init, even though the root filesystem
was successful found (I don't know if that is significant).

With all of mm1 applied, and with X86_4G selected, it boots fine.
But without X86_4G it doesn't get to print out any messages at all,
even with 'earlyprintk=vga' set.

I am happy to experiment with if you or anyone has patches you would
like tested.

weird. 2.6.4-mm2 boots fine here (both 4g and non-4g). Could you send me
your .config?

(btw., 2.6.4-mm2 needs the attached trivial fix to compile.)

Manfred found and fixed one bug, but that was newly added in mm2.


DEBUG_PAGEALLOC switches to nopentium mode: otherwise a change_page_attr
could cause a split of a 4 MB page, which could cause a gfp which might
deadlock.

Two parts of the cpu initialization cannot be done early: the f00f bug
workaround needs a working paging setup, and loops_per_jiffies is only
initialized after the timer is running.  And everything in setup_arch instead
of before start_kernel: The first printk line should be the "Linux verion xy"
line from start_kernel.

Re: 2.6.4-mm1 - 4g patch breaks when X86_4G not selected

hm. Since your .config boots on akpm's box, this is some BIOS dependency
creating an early-boot problem i fear. Debugging such bugs is hard. One 
way would be via the PC speaker:

	movb $0x3,%al; outb %al,$0x61

this will cause a continuous beep on a typical PC - it works in 16-bit
code too, doesnt have any memory-model assumptions, etc.

the first place to put this would be startup_32 - do we get to this
point at all? (check CONFIG_4G first, to make sure the beep triggers.) 
If it beeps, then move it down until you find the place that crashes.

Thanks for the pointer. I now have something useful to report.

start_kernel calls setup_arch 
 which calls paging_init
 which calls pagetable_init
 which calls setup_identity_mappings
 which calls page_address

If I put 
        asm("push %eax; movb $0x3,%al; outb %al,$0x61; popl %eax\n");
before the call to page_address, and
        asm("push %eax; movb $0x0,%al; outb %al,$0x61; popl %eax\n");
afterwards, then I get a tone after boot, suggesting that page_address
isn't returning.

I'm guessing that the problem is:

page_address calls
	spin_lock_irqsave(&pas->lock, flags);

but the spinlock isn't initialised by page_address_init 
until much later in start_kernel.

That is useful, thanks.  Sorry about the hassle.

Calling page_address_init() earlier isn't the fix though - pmd pages aren't
in highmem so we should never have got that far.  Looks like the pgd or the
pmd page contains garbage.  Did you try it without CONFIG_DEBUG_SLAB?

Nick was seeing slab 0x6b patterns on the NUMAQ, inside the pmd, so there's
some consistency there.  We do have one early setup fix from Manfred, but
it's unlikely to cure this.

I'll have a play with your .config, see if I can reproduce it.  If not I'll
squeeze off -mm3 and would ask you to retest on that if poss.

Without CONFIG_DEBUG_SLAB, it boots OK.

When it comes, I'll test it.

i tried Neil's bzImage and it hung on a stock PC too.

Me too, with CONFIG_DEBUG_PAGEALLOC.  We had a fatal bug around that.

However it seems that Neil's machine is dying with CONFIG_DEBUG_SLAB=y,
CONFIG_DEBUG_PAGEALLOC=n, for which we have no explanation.  It seems that
we're getting use-after-free errors against the pgd's.

Maybe it was the early-x86-cpu-detection.patch bug biting in two places -
let me brew rc1-mm1 and we'll see.

Re: 2.6.4-mm1 - 4g patch breaks when X86_4G not selected

[Ingo Molnar]

another thing: the bzImage is pretty large (1.7MB) - maybe 4G just
pushes the size of the kernel past some size limit. Same for SLAB_DEBUG.

[PATCH][2.6-mm] setup_identity_mappings depends on zone init.

I spent a bit of time on this today, and the problem appears to be that we haven't
done mem_map or zone initialisation, so mem_map[pfn]->flags is also wrong
(e.g. PG_highmem tests). This is still triple faulting on 2.6.5-rc3-mm4 on my
boxes. CONFIG_HIGHMEM and any setup without 4MB pages should do it. The
following patch got an approving nod from Bill.

A nicer fix, though with potentially too high a "cleanup factor", would
be a pte_bootmem_alloc_map() or some such equivalent of pte_alloc_map().

It seems to work fine for desktop use.
I compiled with regparm, 4k stacks, and checking for stack overflow.
