What was the last known good kernel?

Have you updated the user space graphics components (the Xorg server, Mesa,
the Xorg radeon driver)?

All r7xx asics are affected by that issue, including the rv730.

WTF -- this ended up in a bisect pointing to some PCMCIA patch! Justin:

  * does this happen with wireless-testing.git ?
  * Did you do the bisect on the entire kernel? What git tree are you
using to bisect?

Did you simply bring up the interface and then suspsend? Did you not
add a new interface in between this? ath5k's add_interace has:

        if (sc->vif) {
                ret = 0;
                goto end;
        }

But why does it just allow this to go through without complaining if
multiple vifs are not supported?

I see no updates to this since August. There are boat load of PCMCIA

Pavel already verified the PCMCIA-bigdiff since 2.6.35 does work, so it is
_not_ a PCMCIA issue.

no this is the current Linus tree(have not tried any other tree).
as for the unresolved regression, this just was filed a few days ago..

the bisect had to be between 2.6.34 and 2.6.32 due to pcmcia breaking 
after 2.6.34(there is a bug report for that, but got resolved)

the system is opensuse 11.2, I just simply start the machine boot up,
after nm connects I open a terminal then suspend in the terminal, upon 
wakeup this message appears.

yeah the first pcmcia bug I hit with this machine was back in may/june 
ended up doing a bisect for that(which was painful due to a slow 
machine)which ended up getting fixed.(never thought to check s2ram after 
that)

as for bluetooth the only issue I have with that is for my other 
machines which is hitting this: http://lkml.org/lkml/2010/9/1/61
(but have not had a chance to follow through due to doing the update 
broken web addresses in the kernel)

--- Comment #4 from Duncan <1i5t5.duncan@cox.net>  2010-10-12 14:45:49 ---
I seem to have missed a couple email update notifications...

The status as of 2.6.36-rc7-149 (pulled a couple hours ago) is basically
unchanged, if not slightly worse.  Without the revert, I still can't get into
X/KDE.

The "slightly worse" is because I've updated to kde 4.5.2 now, and it won't
take xorg.conf, section module, disable "dri", at all -- it crashes X instead,
leaving me back at a KMS text mode command prompt.  I tried with earlier
kernels that worked before (with kde 4.5.1 and no dri), too, and it still
failed, so that's NOT a kernel issue, but it does mean I have no working method
of testing no-dri at all.  I can get working dri on the old kernels (or the new
one with that commit reverted), but can't test no-dri on any kernel, now.

The last tested good kernel was 2.6.35, as I thought was plain based on the
bugs I noted it was a followup to.  I still get a working kernel with commit
44437579efca258e3c4a09f59838c8f933611990 reversed, basically, in
drivers/gpu/drm/radeon/r600.c and etc,

WREG32(R_005480_HDP_MEM_COHERENCY_FLUSH_CNTL, 0x1);

instead of the if statements my hardware is obviously coming up on the wrong
side of.

FWIW, 2.6.35.4 and 2.6.35.7, which I tested from the stable series, have the
same problem.

I already mentioned that I'm running the latest kde 4.5.2, and you know my
kernel is testing series.  xorg-server, mesa, libdrm, and xf86-video-ati are
equally updated; I'm currently running xorg-server 1.9.0.901 (1.9.1-rc1), tho I
tested 1.9.0 as well, mesa 7.9, libdrm 2.4.22, and xf86-video-ati 6.13.2.  gcc
4.5.1 is the current compiler, with a fresh full system rebuild a couple days
ago, and I'm running glibc 2.12.1 (gentoo revision -r1). Some of those are
updates from the original report back on bug #17702 which this is a clone of.

Possibly complicating factors include AGP, and AMD 8000 chipset so including
agpgart IOMMU taking up part of the AGP window.

If all r7xx are affected, why on earth is it working for me with that commit
reverted, and not working for me with it applied?  Based on the fact that my
Radeon 4650 card is quite new, I'm still wondering if, somehow, whatever
problem that commit I'm reverting is supposed to fix doesn't apply to this card
revision.

Or perhaps it's a mixup with AGPGART.

I did note one of the recent drm/radeon commits updated an ID to categorize it
correctly, but the retail package labeling, the kernel, and the radeon manpage,
all seem to agree that the hd4560 I bought should be an rv730, so it'd seem the
ID is right.  But the hardware sure doesn't like the stuff in that if statement
I'm reverting, that's for sure, whatever the reason may be!

Meanwhile, if you can come up with a patch to give you information a bit more
useful, or if you just need more dmesg output (beyond what's posted to the
original bug), just ask and I'll do what I can.  I have been working some
pretty crazy hours lately, however (in addition to those missed email
notifications), the reason my followups haven't been as timely as I'd have
liked.

DRI is enabled by default in the xserver, and there's no way to disable it with
kms.  I'm not sure what you were getting before without seeing your X log.  You
can disable acceleration in X with:
Option "NoAccel" "TRUE"
in the device section of your xorg.conf

It could be general AGP problems.  Does disabling AGP help?  Boot with
radeon.agpmode=-1

--- Comment #6 from Duncan <1i5t5.duncan@cox.net>  2010-10-13 14:12:11 ---
[Grumble!  My prefs are set to mail for all comment additions, but I'm not
getting them ATM!  Is this a known bugzilla.kernel.org issue ATM?  Maybe it's
my ISP eating them as spam?  Anyway, I know to check manually now.]

With KMS and previous xorg-server versions (1.9.0 at least, as mentioned on the
previous bug), Option "NoAccel" in the device section didn't seem to do
anything, but Disable "dri" in the Modules section did just that.  The xorg log
confirmed it.

With the current setup, I was blaming it on kde 4.5.2 but maybe it's xorg
1.9.0.901, the Modules section Disable "dri" works (disables dri) according to
the log, but I get either no X graphics or only a fraction of a second of
graphics, before it switches back to the KMS mode text VT I was in previously.

And yes, I know dri was disabled previously because not only kde had no OpenGL
effects, but glxinfo reported the mesa software rendering OpenGL fallback, not
the radeon hardware OpenGL rendering I normally see.

Hmm.... but one thing different that I forgot about that I bet has something to
do with it...  And I better check the variation against this bug now that I
remember it, somewhere during my testing I commented the
LIBGL_ALWAYS_INDIRECT=1 that I was previously exporting.  But I'd have not
messed with it if I'd not had the reported bug to begin with, so I doubt it
fixes the problem entirely, but it could well explain why I could boot to KDE
with DRI disabled before, and I can't, now.

So I have some more config variant testing to do.

Meanwhile, is the radeon.agpmode=-1 boot parameter like the xorg.conf device
section Option "AGPMode" "int" or Option "BusType" "string" that I used to use
and that's still documented in the radeon manpage?  Do those do any good now
with KMS or are they ignored in that case, with only the boot parameters having
any effect?

Anyway, I'll try to test after some sleep.  The results I'd get ATM might be
less than useful. =:^(

Correct.  the agpmode module parameter is a combination of those two xorg
driver options. -1 uses the on board GART mechanism rather than the northbridge
provided AGP one. 1,2,4,8 specify the AGP mode when using the northbridge
provided AGP GART.  When KMS is active, the AGPMode and BusType xorg.conf
options are not used as KMS configures the hw independent of X.

Thanks for the explanation.

LIBGL_ALWAYS_INDIRECT=1 didn't get back my working xorg.conf module-section
disable dri, unfortunately.  I was hoping it would.  But I swear it disabled
dri at the time of my earlier test, even with kms, with xorg-server 1.9, etc,
now updated.

I'm double-checking that boot-param now, in ordered to test it.

--- Comment #9 from Duncan <1i5t5.duncan@cox.net>  2010-10-14 18:58:11 ---
Unfortunately, while I could verify from dmesg that the kernel was indeed using
radeon.agpmode=-1, it didn't help. =:^(

I verified that radeon.agpmode=-1 DID work with the culprit commit reverted,
just as normal mode did, so it wasn't some other problem with it.  And, for
good measure I checked radeon.agpmode=4 as well.  As expected, it worked on the
kernel with the revert, but didn't without the revert.  (This is still the
rc7-149-g29979aa I'm testing, FWIW.)

Meanwhile, with -1, dmesg says PCIE mode.  That's PCI (not E) mode too, right? 
Because this system's too old to have PCIE at all, tho it does have PCI-X. 
Since it works on the revert-kernel I expect it's correct, but just verifying.

Also, GTT memory is 128 MB in normal mode, 512 MB with -1.  Again, that's
normal, right?  (FWIW, 6 gigs system RAM, 1 gig vram, 256 MB AGP  aperture,
split down the middle between AGPGART IOMMU and actual AGP usage.)

I tried a bunch of other stuff too, including radeon.modeset=0 (didn't work in
X for either the good or bad kernel) on the bootline, xorg.conf SWCursor,
color-tiling both on and off (no change to results, good kernel worked, bad
didn't), etc.

What's next?

As of 2.6.37-rc1-170-gf6614b7, the problem remains.  Reverting
44437579efca258e3c4a09f59838c8f933611990, X/KDE (now kde 4.5.3 and xorg-server
1.9.2) runs.  With the straight Linus kernel, it freezes just as the desktop
appears.

One thing I'm not sure I've mentioned that might or might not help.  kwin
checks for supported OpenGL and (with the revert above, of course, as otherwise
it crashes before I get to that stage) turns effects off initially.  I have to
use the assigned effects toggle hotkey to turn them on.  This is apparently a
known issue with the xorg/kernel-native radeon driver at this point, with kwin
playing it safe by turning them off to begin with if it's not sure.  But
effects work in general (with the occasional non-fatal bug, the invert effect
simply turns everything white, instead of color-inverting like I believe it's
supposed to do, for instance, but it's a nice effect if I want a bit more light

(In reply to comment #12)
> Does this patch help?

Yes!  That patch eliminates the problem (and current git as of
v2.6.37-rc5-26-g2cedcc4 still has the issue, without the patch).

As mentioned, this has affected stable 2.6.35 and all of 2.6.36 as well, so
applying this to the stable tree for both should be considered as well as
2.6.37, once you're sure it's unlikely to cause other problems.

FWIW, with the patch applied, I'm getting the best and most glitch-free OpenGL
accel I've ever seen on this hardware.  It's quite nice not to see or know of a
single glitch.  Now /this/ is what I purchased this r7xx Radeon upgrade for! 
=:^) 

And, even tho there were a couple glitches still and I had that one commit
revert, I had an uptime of nearly a month on 2.6.37-rc1-170-gf6614b7, before I
rebooted to test current, so everything's pretty stable too, it seems.  2.6.37
might well be the best kernel I've seen in awhile. Certainly, I don't believe
I've seen that sort of stability just after rc1 for some time.  =:^)

Tried the patch on 2.6.36.1-2 (RV730 AGP)
Not much luck:
With KMS the system will boot into a black screen and lock up.
With UMS (nomodeset in kernel command line) it will show X, but freeze while
the window manager is loaded.
Guess I have to wait for 2.6.37 to become integrated into my distro.

--- Comment #15 from Holger Lenz <holger.lenz@onlinehome.de>  2010-12-13 19:56:36 ---
Did some more homework:
Compiled kernel 2.6.37 rc5, taking care to enable KMS (new driver) by setting
DRM_MODESET_KMS=ON.
Unpatched and patched drivers show the same behavior:
1. Boot without nomodeset in the kernel cmd line: Blank screen before X is
fully loaded.
2. Boot with nomodeset in the kernel cmd line: X loads with radeon/R600 classic
driver is is reasonably quick in 2D, but a lockup occurs sooner or later.
Switching from X to fb terminal usually does the trick quickly. The patched
driver seems to lock up more quickly.
Any ideas what I could do to help you fix the bug?
Hardware is similar to Duncans: AMD K8, VIA K8T800 chipset, Radeon HD 4650 AGP
(RV730)

Holger, your issue may not be the same as Duncan's.  I'd suggest changing the
AGP mode in your bios or adjusting it or disabling it via the kernel command
line (radeon.agpmode=-1 to disable, 1,2,4,8 to force the agp mode). It might
also be related to the latency setting on the host bridge.  VIA boards tend to
set them pretty aggressively.

You may be right: Still using the patched driver I set radeon.agpmode=-1 and
the system came up with X using radeon and swrast. Seems like radeon.agpmode=-1
switches off dri / the r600 classic driver. A few switches to the fb console
broke the vt session, but I was always able to switch back to X.
Unfortunately I cannot get AGP to work with the radeon driver. Using really
conservative settings in the AGP bridge, the driver still doesn't boot without
radeon.agpmode=-1. I used the following BIOS settings to get moderate timings
AGP Mode=4x
VLINK 8x disable
AGP 3.0 calibration cycle enabled
DBI output for AGP transactions disable

The hardware itself should be pretty stable - I ran a heavy Furmark stress test
under windows to check for robustness.

Any ideas how to debug the AGP issue?
BR Holger

New info before getting some sleep: The system was using swrast above because
it didnt use kms. If I force KMS by using radeon.modeset=0 on the kcl, radeon
and r600 will be loaded even if i set radeon.agpmode=-1. The system will then
freeze after loading X and showing a few windows. So the improvement w/o AGP is
not freezing immediately.

--- Comment #19 from Duncan <1i5t5.duncan@cox.net>  2010-12-14 03:05:58 ---
Some additional notes, FWIW.  May help compare the two installations, mine now
working with either the original reversion or the new patch, his, not.

1) I've been using 100% KMS since the choice was still in staging.  Last time I
tried radeon.modeset=0 (see comment #9) I had problems and immediately switched
back to KMS, which worked.  My conclusion then was that UMS was being disabled
or at least strongly deprecated, which was fine with me as I prefer KMS, but it
seems that was incorrect and it's still available.

2) No AGP fast-write here at all.  AFAIK it's a chipset errata on AMD 8xxx.

3) 256 MB AGP aperture, half of which is of course reserved for the AGPGART
IOMMU on the AMD 8xxx chipset.  The BIOS allows larger (upto 1GB, which happens
to be video memory size as well), but that was a reasonably late addition to
the BIOS (256 was the previous limit), and for whatever reason I couldn't get
it to work in testing, so I've stuck with 256 MB (128 MB of it AGPGART IOMMU),
which /does/ work.

BTW, /should/ a larger aperture work?  Given that half of it's AGGART IOMMU,
should larger == better?  I've not tested larger recently, maybe it works now?

4) dmesg says AGP v3 device in 8x mode.  Years ago I had problems with 8x and
had to use 4x max, but last I tried, 4x and 8x worked but 1x and 2x were
broken.

5) I've been using the classic r6xx/r7xx driver, not the new gallium stuff,
which I've not gotten to work yet.  (On Gentoo, I'm naturally compiling my own.
 At one point it compiled but I wasn't aware then how to switch to it.  Later I
figured that out, but had to turn off LLVM  to get it to compile at all, and I
wasn't surprised when that didn't work.  So I've never actually had gallium up
and running successfully.)

6) I was trying xorg-server 1.9.2.902 (AFAIK, 1.9.3-rc?), but am now back on
1.9.2 stable, as the pre-release throttled DOSBOX performance something
terrible. (I only found out and downgraded yesterday, and haven't filed an X
bug yet.)

7) Further to comment #0/Description, there was a kde image cache bug in early
kde 4.5, fixed with 4.5.4 (maybe 4.5.3).  The comic-strip-plasmoid thing was
related to that, I believe, and is now fixed.

8) It's a bit late to be mentioning this now but something else that could
conceivably be a factor.  Apparently on this old hardware, since kernel 2.6.31,
ACPI and various hardware sensor addresses conflict, and I have to boot with
acpi_enforce_resources=lax or most of my sensors don't work.  I have that
compiled in as part of my CONFIG_CMDLINE, so tend to forget about it.  See
kernel bug #13939 .  The board was long since past its BIOS update period even
back then and I've been unable to find documentation on what sensors drivers
might work in place of the ones that broke, so lax enforcement remains my only
known option if I want sensors output, which I do.  Might that somehow play
into this graphics thing or are they entirely unrelated?

9) Further to comment #13.  I still can't get over how nice it is to (with the
patch applied) have a properly glitch-free OpenGL accelerated X. This is the
/first/ time I've had perfect glitch-free graphics since I upgraded from the
old r2xx based card. In an improvement since comment #11, kwin now comes up in
OpenGL mode without effects disabled (back then I had to manually enable them
once up and running) and invert works fine now too.  2.6.37 has actually been
very stable all around, without the usual assortment of other bugs in the
md/raid system, etc, too.

Thanks a lot Ducan, for all the info.
You helped me eliminate several variables.
AGP still won't work, but I'll just see how far I get with PCI(E) mode
I'm now always forcing KMS by using radeon.modeset=1

Looking at the demsg, the following two errors seem to prevent X from loading
the r600 module:

This (1)
 [drm] Forcing AGP to PCIE mode
[   17.311865] radeon 0000:01:00.0: PCI: Disallowing DAC for device
[   17.311867] radeon: No suitable DMA available.

and this (2)
[drm:radeon_ttm_backend_bind] *ERROR* failed to bind 1 pages at 0x00000000
[   17.485886] radeon 0000:01:00.0: object_init failed for (4096, 0x00000002)

any ideas, how to fix these?

It's buggy on all boards.  We don't enable it at all with kms.

Bigger isn't necessarily better, it just means more pages can be mapped into
the gart.  We default to 512 MB on non-AGP systems.

AGP v3 devices only support 4x and 8x modes.

Try adding radeon.no_wb=1 to your kernel command as well.

Also, some boards set unrealistic latency settings on the AGP bridge the card
is plugged into.  Often increasing the latency with setpci will improve
stability.
lspci -vv will show you what it's currently set to.

No luck with radeon.no_wb=1, unfortunately.
Attached lspci -vv - no idea if the timings are aggressive or not.

So, radeon.no_wb=1 didn't help. Is there a way to get enough debugging info to
nail the bug / create a workaround?

Can you attach your dmesg with agp enabled using 2.6.37 with the patch on this
bug applied?  Also, what agp aperture sizes were available in the bios? Can you
try changing the agp size in the bios and see if that helps?

Is there, anywhere, any documentation with reasonable information on what
settings in the xorg.conf and radeon manpages no longer apply in xorg.conf with
kms, and what the parallel radeon.* kernel commandline options are?

Either updating the manpages, or a separate kms manpage (with suitable SEE ALSO
section mentions from existing manpages), would be /wonderful/.  Or a kernel
Documentation/radeon.txt or kms.txt file.  (And, couldn't all the kernel
display/graphics related Docs be moved into a display/graphics/video subdir? 
Seems about time.)

Because I really feel like a blind man simply poking things to see what
happens, reverse engineering what shouldn't need to be, if you will.  Plus
chance comments like this, giving me info I had no idea about.  Surely I'm not
alone, and a good many "bugs" could be eliminated if people only knew about
various available settings.

Thanks.  Useful information.

Now if only that were documented in the manpages... =:^(
It does explain why modes below 4x wouldn't work, tho. =:^)

The patch above was committed as f3886f85:

Author: Alex Deucher <alexdeucher@gmail.com>

    drm/radeon/kms: don't apply 7xx HDP flush workaround on AGP

    It should be required for all 7xx asics, but seems to cause
    problems on some AGP 7xx chips.

Re-verified working.

I'm updated and on the mainline Linus kernel without patches again as of
v2.6.37-rc5-332-g0fcdcfb.  Nice to be back, as I've been unable to go without
first the revert and then the patch above, since shortly after 2.6.35.  =:^)

The bug as filed can thus be closed, from my viewpoint.  But as there's another
one being investigated, I'll leave it open for now.

Should the remaining open bug be re-filed as a separate bug now and this one
closed?  If it is, feel free to CC me if desired.  It's possible the contrast
between my working system and HL's not working system might continue to be
helpful.

I suggest to close the current one and open a new one - there are actually 2:
- Radeon AGP broken on my system and
- Driver not loading (in PCI mode) because of the ttm_background_bind issue
May even be worth openeing 2 new bugs unless you think they are closely
related.
Depends on your defect management process.
Alex?

I updated the radeon man page last week to reflect what options are KMS vs.
UMS.  Grab the latest xf86-video-ati from git master.

It's not really radeon specific, but it would probably be nice to mention it
somewhere.

If you do so, please also post references to the two other bugreports here and
mention this bug in the 2 new bugreports. 

I'm closing this as fixed then.

--- Comment #33 from Holger Lenz <holger.lenz@onlinehome.de>  2010-12-15 20:55:33 ---
YES! I can confirm the fix.
I have the radeon+r600 driver working in AGP mode stable now.
The remaining issues I have been seeing are related to loading the driver:
If I do the following procedure, then radeon/r600 works no matter what I do to
memory holes or AGP speeds:
- Boot to runlevel 3 (ugly 4 char fbcon)
- log in as root
- modprobe radeon (get nice 132 char fbcon)
- init 5
- enjoy X in native resolution and glxgears with 540fps 

Question is, why is radeon not loaded before X is started? Is there a
conflicting framebuffer device (I habe VGA framebuffer compiled in, no
modules). Can I force loading radeon that on the kcmd line?

Depends on your distro's inird and modprode config.  It should load
automatically at boot on most recent distros that support kms.

OK, I'll just add radeon and any helpers it needs to the initrd and be done
with it.

The situation is as follows:
- in AGP mode radeon needs to be loaded manually before X starts (then uses
r600). Probably tries to do this automatically and fails somehow,
- in PCI mode, X with radeon will be loaded automatically (!) The error
described above (ttm_backend_bind) disables r600 and makes X use radeon+swrast

I have not figured this out yet - what to complain about in a new bug report.
