2.6.12-rc1-mm1

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc1/2.6.12-rc1-mm1/

- We might have a fix here for the recent AGP/DRM problems. If you were having problems with that, please test and report.

- An update to the hfs and hfsplus filesystems.

- Lots more pcmcia changes.

- Linus is away this week. Not a lot more should be going into 2.6.12 now and I have a list of ~140 bugs, many of which are post-2.6.10 regressions. We should fix these.

Changes since 2.6.11-mm4:

Hi Andrew,

After tracking down this bug in the X code, Mike Werner asked me to change my patch so that we directly use agp_find_bridge instead of defining a new wrapper (agp_backend_find).
A new patch is attached.

Note that agp-make-some-code-static.patch makes agp_find_bridge
static in drivers/char/agp/backend.c while my new patch exports it.
That's why I also attach a patch to revert this part of agp-make-some-code-static.patch.

Regards,
Brice

Len, why does ACPI now depend on PM? On some platforms it has very little to do with power management, and this breaks the build for sn2...

Andrew, please drop

revert-allow-oem-written-modules-to-make-calls-to-ia64-oem-sal-functions.patch

The tiocx.c driver is now in the tree, and it uses those functions.

Thanks,
Jesse

IOW:
The EXPORT_SYMBOL's should still be removed, but the functions themselves should stay.

Actually, no, since tiocx can be built modular. The patch should just be dropped.

Hm, ok. I just looked at the Makefile and iirc some old versions of the patch allowed it modular...

Fixed by upgrading the userspace script used by him to include

	"cardctl eject && sleep 1"

before killing cardmgr, as killing cardmgr no longer auto-detaches PCMCIA devices and this was what he needs: while suspend/resume does work with PCMCIA in general AFAIK, certain device drivers are faulty.

...

This is no regresssion[*], a fix is being evaluated.

Thanks,
Dominik

[*] It may work on 2.4., though...

This one is a real mystery. No one can reproduce it.

This one is fixed in ALSA CVS. Here is the patch.

OK. But we don't seem to have heard from the originator since March 5th.

But not in http://linux-sound.bkbits.net/linux-sound yet. How does stuff propagate from ALSA CVS into bk?

The ALSA maintainers periodically ask Linus to pull from the linux-sound tree. But that's just the general "ALSA update" process.

I'm not aware of a mechanism for getting critical fixes like this in ASAP. The last few have been shepherded through manually by various people. Looks like we need a better system.

Lee

Oh. I was always under the impression that
http://linux-sound.bkbits.net/linux-sound contains the latest devel stuff for -mm.

It's not a trivial problem.

The linux-stable process seems to be working quite well so far.

Lee

At Mon, 21 Mar 2005 20:23:03 -0800,

sound-bk includes fairly recent codes but not always the very latest since the sync between ALSA CVS and sound-bk trees are done manually by Jaroslav.

We have a mechanism to do sync immediately for critical patches. But I seem to forget to tag it like this case. Sorry for that.

Takashi

I am trying to sync the linux-sound BK tree every week with our CVS. For "urgent" fixes we need to find another faster way. Hopefully, they are in most cases small enough, so they might be propagated automagically. I already proposed special "tag" in our CVS commit policy, so we can identify these patches / changesets.

I will try to prepare some useable tool in few weeks.

Pavel, that's the BUG() in pci_choose_state(). I did have some reject-fixing to do on that wrt a change in Greg's tree, so maybe there was some incompatible intent in there.

I dunno why pci_choose_state() is saying that it received PCI_D1, when prepare_devices() is passing down PMSG_FREEZE?

Hi!

Uf, I don't know what version that was.. I think I have

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 12
EXTRAVERSION =-rc1-mm1

and that says:

#define PMSG_FREEZE ((__force pm_message_t) 3)

... I certainly have _FREEZE defined as 1 in my local tree, but I do not see that change in -mm yet.

Possibly pm.h changes went in faster than pci.c or something like that?

I reproduced it here.. I do not know who introduced platform_pci_choose_state, but it is *very* wrong. It returns it. Should it return pci_power_t? It probably should to match pci_choose_state, but that int is retyped to pm_message_t. Oops.

Pavel

People were complaining that M$ turns users into beta-testers...
...jr ghea gurz vagb qrirybcref, naq gurl frrz gb yvxr vg gung jnl!

yes, the report was against 2.6.12-rc1-mm1.

Both 2.6.12-rc1-mm1 and 2.6.12-rc1 have:

#define PMSG_FREEZE     ((__force pm_message_t) 3)
#define PMSG_SUSPEND    ((__force pm_message_t) 3)
#define PMSG_ON         ((__force pm_message_t) 0)

which looks odd.

grep says that 2.6.12-rc1-mm1 has these patches from you:

fix-suspend-resume-on-via-velocity.patch x86-fix-esp-corruption-cpu-bug-take-2.patch swsusp-add-missing-refrigerator-calls.patch suspend-to-ram-update-videotxt-with-more-systems.patch pm-remove-obsolete-pm_-from-vtc.patch swsusp-small-updates.patch swsusp-1-1-kill-swsusp_restore.patch pcmcia-id_table-for-orinoco_cs.patch fix-pm_message_t-in-generic-code.patch fix-u32-vs-pm_message_t-in-usb.patch more-pm_message_t-fixes.patch fix-u32-vs-pm_message_t-confusion-in-oss.patch fix-u32-vs-pm_message_t-confusion-in-pcmcia.patch fix-u32-vs-pm_message_t-confusion-in-framebuffers.patch fix-u32-vs-pm_message_t-confusion-in-mmc.patch fix-u32-vs-pm_message_t-confusion-in-serials.patch fix-u32-vs-pm_message_t-in-macintosh.patch fix-u32-vs-pm_message_t-confusion-in-agp.patch

That change came from Len. I've appended the two relevant patches below.

So hm. We have incompatible changes in flight. That doesn't happen very often.

Could I suggest that you prepare a fixup against 2.6.12-rc1-mm1 and send that to Len and myself? If that fixup is not suitable for a 2.6.12-rc1 based tree then I can look after it until things get flushed out.

(Len, platform_pci_set_power_state shouldn't be initialised to NULL).

Hi!

Yes, but it is needed. There are many drivers, and they look at numerical value of PMSG_*. I'm proceeding in steps. I hopefully killed all direct accesses to the constants, and will switch constants to something else... But that is going to be tommorow (need some sleep).

Could you just revert those two patches? First one is very wrong. Second one might be fixed, but... See comments below.

And they are both "dangerous" -- they introduce new and untested functionality while I'm trying to transition from int to pm_message_t. They also affect all the drivers.

Len, please Cc me on patches that affect suspend.

		[PCI_D0] = 0,

People were complaining that M$ turns users into beta-testers...
...jr ghea gurz vagb qrirybcref, naq gurl frrz gb yvxr vg gung jnl!

I could revert them locally, but that wouldn't gain us much.

Greg hasn't taken the pm_message_t patches yet. Perhaps that's for the best.

Perhaps I should just jam everything-from-Pavel into Linus's tree as soon as he returns and then we can fix up the downstream fallout in the various bk trees?

You mean that Len has to revert them or revert is "ineffective"?

Yes, that would help a lot. I was waiting with "turn-pm_message_t-into-struct" until all pm_message_t patches reached Linus so that there's not a mess "in flight". Len's patch pretty much depends on pm_message_t already being converted... (and I'd prefer it to wait a while, so we can see which problems were introduced by conversion and which are due to ACPI BIOS bugs).

Pavel

People were complaining that M$ turns users into beta-testers...
...jr ghea gurz vagb qrirybcref, naq gurl frrz gb yvxr vg gung jnl!

The patches are in Len's tree.

OK, well unless someone has objections I'll just send all these

swsusp-add-missing-refrigerator-calls.patch suspend-to-ram-update-videotxt-with-more-systems.patch pm-remove-obsolete-pm_-from-vtc.patch swsusp-small-updates.patch swsusp-1-1-kill-swsusp_restore.patch fix-pm_message_t-in-generic-code.patch fix-u32-vs-pm_message_t-in-usb.patch more-pm_message_t-fixes.patch fix-u32-vs-pm_message_t-confusion-in-oss.patch fix-u32-vs-pm_message_t-confusion-in-pcmcia.patch fix-u32-vs-pm_message_t-confusion-in-framebuffers.patch fix-u32-vs-pm_message_t-confusion-in-mmc.patch fix-u32-vs-pm_message_t-confusion-in-serials.patch fix-u32-vs-pm_message_t-in-macintosh.patch fix-u32-vs-pm_message_t-confusion-in-agp.patch

to Linus when he reappears and then I'll duck for cover and let you guys sort it out ;)

No objection from me, that's probably the best way for this to get into the tree.

thanks,

greg k-h

Hi!

There should be little reason for taking cover, that patches were just anotating types... BTW this is how switch to pm_message_t is going to look. If you are developing something pm-related, you should probably do it against this tree.

The patches are going to acquire correct PCI device sleep state for suspend/resume. We discussed the issue several months ago. My plan is we first introduce 'platform_pci_set_power_state', then merge the 'platform_pci_choose_state' patch after Pavel's pm_message_t conversion finished. Maybe Len mislead my comments.

Anyway for the callback, my intend is platform_pci_choose_state accept the pm_message_t parameter, and it return an 'int', since platform method possibly failed and then pci_choose_state translate the return value to pci_power_t.

I think the platform_pci_set_power_state should be ok, did you see it causes oops?

I suppose it's not exported out side of PCI, so I used 'pci.h'

Should return int as I said above.

Yep, this should be fixed.

Ok, please revert the 'platform_pci_choose_pci' patch, I will add it after Pavel's conversion is finished. Or after Pavel's is done, I can send a quick fix.

Thanks,
Shaohua

Will this do it for the moment?

If so, lets use it until Pavel's flag-day is over -- when we'll send an updated patch.

Its certainly better.

Hi,

With the Len's patch applied I have to unload the modules:

ohci_hcd
ehci_hcd
yenta_socket

before suspend as each of them hangs the box solid during either suspend or resume. Moreover, when I tried to load the ehci_hcd module back after resume, it hanged the box solid too.

Hi,

This behavior is apparently caused by the call to pci_write_config_word() with pmcsr = 0 in drivers/pci/pci.c:pci_set_power_state().

Well, I don't think I can do anything more about it myself. :-)

Is this failure with suspend to RAM or to disk?

How about if you try this patch?

http://linux-acpi.bkbits.net:8080/to-akpm/cset@423b4875tyauh4CrSSoQfXOEPDkmUw

patch -Rp1 from 2.6.12-rc1-mm and see if it stops being broken or patch -Np1 to 2.6.12-rc and see if it starts being broken.

This one removes an earlier attempt at resuming PCI links -- now putting the onus on the drivers to be properly written
to release and acquire their interrupt for a successful suspend/resume.

In theory, this is taken care of something like this:
driver.resume
pci_enable_device
pci_enable_device_bars
pcibios_enable_device
pcibios_enable_irq
acpi_pci_irq_enable

but if the patch above makes a difference, then theory != practice:-)

I'd believe that ohci_hcd and ehci_hcd are fragile since glancing at their lengthy .resume routines it isn't immediately obvious that they do this. But yenta_dev_resume has a pci_enable_device(), so that failure may be less straightforward.

cheers,
-Len

ps. if point me to a full dmesg -s64000 from 2.6.12-rc1 acpi-enabled boot, that would help -- for it will show if we're even using pci interrupt links (and programming them) for these devices on this box.

Yes, we changed the behavior of device suspend/resume. Every PCI device should call 'pci_disable_device' at suspend and call 'pci_enable_device' at resume. It fixes a bug and more important thing is it's safer (Eg. it disable interrupts, bus master and etc).
I actually added such calls in uhci, ehci and yenta. It's ok for S3 (and definitely required for S3). Unclear if it's ok for S4, so please try revert the patch.

Thanks,
Shaohua

Hi,

It looks like that. ;-)

2.6.11-rc1-mm1 with the patch reverted works fine. :-)

So just remove the pci_enable/disable_device call in the driver makes the system work? Strange, I tried them on two laptops (one HP nx5000, and one Toshiba M2N), both works (no hang, and USB mouse works after S3/S4. I didn't try yenta, since I have no pc card) for S3/S4. Is it possible it's another bug or just because of different BIOS?

Hi!

You can't just retype around like that. You may want it take pci_power_t * as an argument, and then return 0/-ENODEV or something like that. But you can't retype between int and pm_message_t...

Plus that function should have a documentation somewhere!

No its just ugly and uses __force in "creative" way. That one can be recovered.

Hi!

Actually, there's one even more severe problem with platform_pci_choose_state...

If we are doing freeze for swsusp snapshot (or freeze for kexec or something similar, that ACPI does not know about), it is very wrong to ask ACPI to tell us power levels for devices. ACPI does not even know about those states, it can not tell us anything meaningfull.

So if this hook is to be reintroduced, it should go down in the function, and only trigger for ACPI S3 and ACPI S1 cases. Maybe for swsusp/plaform (== ACPI S4).

But I'd prefer the hook to go away for now, it clearly needs infrastructure that is not yet there, and provides nothing.

Thanks; I'll fix these and submit a patch (or two) after some testing.

OK.

This seems to be somewhat obsolete now since most drivers have moved to use get_drvinfo of ethtool_ops; I'll do the same.

OK.

This is actually very common for PC Card drivers in the current kernel tree.. I'll change Host AP to kmalloc this, but someone might consider going through all *_cs.c drivers..

Hi Hans,

REISER4_FS is the only option with a dependency on !4KSTACKS which is bad since 8 kB stacks on i386 won't stay forever.

Could fix the problems with 4 kB stacks?

Running

make checkstacks | grep reiser4

inside te kernel sources after compiling gives you hints where problems might come from.

TIA

All of my technical arguments on this topic were nicely obliterated by Andrew. The only real reason remaining (that I know of) is that I want to first eliminate all things which are a barrier to inclusion before dealing with this because it requires man hours to fix it. If you want to send us a cleanup patch that fixes it, I would be grateful for your time donatioin.

Hans

My plan is to send a patch to Andrew that unconditionally enables 4KSTACKS for shaking out the last bugs before possibly removing 8 kB stacks completely.

I don't know whether this is barrier to inclusion, but this will make reiser4 unavailable on i386...

In that case you might find this output relevant. It was generated for 2.6.11 (no -mm).

Without recursions I cannot find a single code path chewing up 3k or more, so any bugs will likely be somewhere in this list.

Victory in war is not repetitious.
-- Sun Tzu

Sigh. Could you wait a few weeks until we have done all the other
things, and then I can have Vladimir work with you on it?

I'd be interested to find out what the problem is as well; after all even with 8Kb stacks your net available stack is somewhere in the 5Kb range anyway... so you're really close to the edge there.

Actually, I've run the Big Ol' checkstack program on reiser4 once. Without recursions, the code is well below 3k, but some of the recursions look a bit daunting. Here is the relevant output:

People will accept your ideas much more readily if you tell them
that Benjamin Franklin said it first.
-- unknown

Maybe I should change the output. "too long" simply means "user gave a stack limit below this value". 2808 bytes is the most expensive path for reiser4 without recursion, so my limit was 2800. ;)

Jörn

When people work hard for you for a pat on the back, you've got
to give them that pat.
-- Robert Heinlein

These would have been missed by the grep I suggested due to the missing reiser4_ prefix.

That seems to be a generic issue in fs/locks.c .
It seems this is the "struct file_lock fl"?

We just send an update to Andrew and Jeff that also fixes this issue. Sadly that patch is >300k so we cannot post it to the list.
