Just a random thought: if I understand it correctly, CPU hotplugging is
intended to be able to take CPUs online and offline one by one, am I
right? Well, when that infrastructure's ready, this can probably be made
to work for SMP by taking all the other CPUs offline first. They're all
going to go offline because of the suspend anyway, so it shouldn't make
much difference. :)

Not at all, it's standard Linux kernel convention, it won't
change. Explicitly zeroing out variables cause more damage since it
transfers them to the data segment from the bss segment.

It works, IMHO it's ugly, but if you find it helps, go ahead. I'd rather
leave a comment like /* uninitialized global variables automatically go
to the bss and get zeroed out */

That may be the case, but in the process I think you are destroying
vital information about which variables the code depends on being
initialized to zero. If the Linux kernel ever changed its policy, or if
the code was used in something other than the Linux kernel (perhaps even
being translated to some other computer language), you would need that
information again.
I suggest commenting out the assignment instead of deleting it:
static int foo /*= 0*/;

BTW, Rusty - what are the locking rules for cpu_online_map under hotplug?
Is it RCU or something? The sched domains usage of it doesn't seem to take
any locks.

I just updated my kernel with your latest changes in cvs and it looks very
good.
I cannot reproduce the problem any more, so it seems to work
with Howards fix!
Thanks for the quick help.

The patch has never been posted seperately. It is part of a patch set for
autofs4, to support the autofs 4.1.0+ daemon, that I sent to Andrew
Morton. I was hoping that Jeremy would review them and they would make
their way to Al but perhaps neither has had time to follow up.
I must add that Mike has pointed out that the vfsmount_lock, used by the
patch is not exported and the patch does not change that.

What do you mean, precisely? You're still describing the imagined
solution rather than the problem.
Case sensitivity is more clearly applicable in _lookup_ -- when trying
to find a given file from its name.
In the case of file _creation_, that affects the collision detection --
case insensitivity will usually cause you to be forbidden from creating
a new file with a name which differs from an existing name only in case.
Is that what they want it for? Why -- what is the real source of the
requirement?

It is fairly painful -- you have to provide your own dentry_ops for
comparison and hashing, which mostly sorts out the evil dcache coherency
issues we used to have with case-insensitivity.
But you still have to know the character set. That was vaguely OK for
FAT, where we had to play charset games anyway, but I _really_ don't
want to have the JFFS2 code play with character sets and know that û is
really the same as Û, etc. And don't get me started on Ŵ and ŵ :)
You really ought to be able to do this in userspace.

Anything that reads anything from a filesystem updates the atime, I
guess, even though the read data comes from the cache. This means that
pages are dirtied, and they need to be written back. The atime is part
of the filesystem metadata, so that might explain metadata journaling
activity. AFAICS your system is not truly idle w.r.t the disk in
question. Mount it with noatime and see if you can spin it down when you
know it should really be idle. (You can use hdparm -y on it to spin it
down by hand, so you don't have to wait for the hardware timer.) If it
still spins up without atime, you know it isn't really idle, so you need
to find out what app is accessing the disk. A look at the output of
"lsof" can be enlightening. If that doesn't help, you can try to use
laptop mode's block_dump functionality (without enabling laptop mode
itself!) to see which process is reading/writing which block.
Laptop mode is not in 2.6 mainstream yet, it can be found in the -mm
series. After you're done using block_dump you can get rid of laptop
mode again: you don't need the actual mode, the spun-down times it gets
you are way too short for your needs. Furthermore it's indiscriminate
w.r.t disks, so it would have an undesired effect on your other disk as
well.

From: Martin J. Bligh @ 2004-01-27 15:14 UTC (permalink / raw)
To: linux-kernel; +Cc: jaba
http://bugme.osdl.org/show_bug.cgi?id=1959
Summary: cs46xx driver mmap_valid 0-->1 in kernel 2.6.x?
Kernel Version: 2.6.x
Status: NEW
Severity: normal
Owner: drivers_sound@kernel-bugs.osdl.org
Submitter: jaba@mikrobitti.fi
Distribution: Gentoo Linux
Hardware Environment: Asus A7V133, AMD Athlon
Software Environment: Gentoo Linux 1.4, default-x86-1.4, gcc-3.3.2,
glibc-2.3.3_pre20040117-r0, 2.6.2-rc1-mm2
Problem Description: This problem has been bothering me all over the kernel
2.6.x. I don't know if any other applications are affected by this bug, but a
game called Enemy Territory surely is.
With the default kernel 2.6 cs46xx driver (with "new DSP support" enabled) the
sound in Enemy Territory doesn't work at all, complaining "unable to mmap
/dev/dsp" during the ET startup. But if I do the patch below to cs46xx.c, sound
starts to work.
The patch I've used:
---
--- cs46xx_old.c 2004-01-27 14:09:46.625277768 +0200
+++ cs46xx.c 2004-01-27 12:32:28.000000000 +0200

+static int mmap_valid[SNDRV_CARDS] = {[0 ... (SNDRV_CARDS - 1)] = 1};
---
Is there a reason to keep mmap_valid=0 in cs46xx driver or is this a real bug? I
haven't seen any new bugs with this patch applied, all the multimedia
applications (mplayer, xine, xmms, noatun) keeps on working.

* Half-success: acpi swsusp in stock 2.6.1 on a vaio PGC-FX701 laptop
From: Romano Giannetti @ 2004-01-27 15:12 UTC (permalink / raw)
To: linux-kernel
Hi all,
this mail is to tell you about an half-success. I am trying to run a
2.6.1 (stock) kernel with my vaio pgc-fx701 laptop running Mandrake 9.2.I am
in the phase of trying to have the suspend option working. The stock kernel
swsusp "almost" work: it suspend the laptop, it resume it almost ok: but
neither usb mouse nor alsa works in the resumed machine. Ethernet works.
I read on the kernel-list archive of the possibility of unload/reloading
the drivers on resume, but I have another problem: compiling the "module
unloading" option in the kernel make kudzu generate an oops at early boot
stage.
So, before continuing: can I help with debugging? Or all these problems
are well-known and simply I have to wait for the 2.6.2 kernel? If you need
the above-mentioned early oops, tell me; I will try to reproduce it and copy
it by hand (it was not so long; EIP was invalid, so...)

I suspect that this is caused by unfinished handling of simplex devices
in setup-pci.c (simplex host - one DMA engine but two channels).

I've seen this and decided that it is not needed.
If we try to program drives to DMA on non-DMA host
something is going wrong and it is better to just OOPS.

We certainly *don't* want to do that, last time I checked C did not
actually guarantee to zero out uninitialized variables -- unless it's
different in the kernelspace. Are you sure pointers are initialized as
NULLs?
Len, I'll prepare a 0.27 patch against bk, so you might want to wait for
that instead of reverting the change.

Thanks. To solve the first problem, I'll just add an "enable FW_LOADER" in

* ACPI versus VIA IDE controller?
From: walt @ 2004-01-27 15:03 UTC (permalink / raw)
To: Linux Kernel
I know there has been a problem getting the VIA ide controller
to cooperate with ACPI, but I saw a bunch of acpi changes coming
from Linus today so I reenabled acpi in my 2.6.2-rc2 again just
out of curiosity.
I still see the message about the VIA ide controller:
ACPI: No IRQ known for interrupt pin A of device 0000:00:11.1 -
using IRQ 255
I haven't exercised the machine much, but it all seems to be
working just fine so far.
Are there any known risks to running the machine in this mode?

Checked with 2.6.1 from unofficial rpms compiled by
bhcompile@porky.devel.redhat.com, results are the same. Plain Linus
2.6.1 kernel still does not work for me in RH9 (some problem with
initrd, needed modules failed to load, I don't know why, yet, I'll try
to solve it). 2.6.0-1.104custom is kernel from similar rpms compiled by
myself (i turned off APM support).

User space people want the file name case insensitivity. I guess the
old files are likely to be selected from a list on an embedded device.
However case insensitivity is a desirable feature when adding new file
names.
My primary concern was to estimate the cost or pain of implementing
file name case insensitivity and find arguments against doing it in
the kernel.

* nvidia nforce3 support
From: Frank Aune @ 2004-01-27 14:56 UTC (permalink / raw)
To: linux-kernel
Hello,
What is the status for nforce3 support in 2.4 and 2.6? Ive found a patch from
google dating all the way back in nov 2003, but it doesnt seem like its been
applied. FYR here is the google search link:
http://groups.google.com/groups?q=nforce3
+linux&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=JSef.Wi.19%40gated-at.bofh.it&rnum=1
When trying the agpgart and nvidia_agp module on my nforce3 system, I get this
message in dmesg:
agpgart: Detected an NVIDIA nForce/nForce2 chipset, but could not find the
secondary devices.
Right now Im using 2.6.2-rc2-mm2, but 2.4.24 also give the same message. What
is this "secondary devices" it cant find? Is this related to an unsupported
AGP card? (Im using an Creative ATI Radeon 9200SE, and I cant enable direct
rendering - only been able to use X version 4.3.99.902 and its built-in
driver.)
I'll be happy to provide DeviceIDs and test patches, if someone needs it.
Thank you.

Mailman lets you filter on certain headers though, and trap messages for
moderation. Can't you do something like looking for a Message-ID
matching ^$ ?
Likewise Return-Path matching <>?
