Frederic? Right. In fact it wasn't a regression. The per task breakpoint reservation design was broken from the beginning and this warning has revealed the problem. This only touched perf, and it did since perf support breakpoints. Fortunately ptrace wasn't concerned by this problem, even not by side effects of this. The fix is invasive as it's a rewrite of a (little) part of the breakpoint reservation. And since the symptom is only a warning and also breakpoints never released from the constraint table (just a counter, no memory leak), the fix is headed for 2.6.36. It is ready in tip:/perf/core: http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=45a73372efe4a63f44aa2e1125d4a777c2fdc8d8 I think this ticket can be safely closed.

Don't have time to test, but I confirm that running compiz without
mode-setting (ubuntu 8.10) hangs the system. (device is i945)
It might be related to few intel regressions on this list.

The symptoms are: - the system hangs hard (~ 50% of the time) when starting Xorg - the system hangs hard (~ 50% of the time) when stopping Xorg during system reboot - the system sometimes hangs hard during suspend to RAM These problems are not reproducible with the commit above reverted.

Below is the information about the graphics adapter from lspci. Reverting that commit on master fixes it? that commit touches code paths in rv770 and evergreen that in no way should affect that chipset which is an rs780, so takes the r600 paths. are you sure its not 7ac9aa5a1f1b87adb69bcbec2b89e228f074103a? It should be that commit if it is indeed the voltage adjust. That said, I just took a closer look at the voltage adjust on newer IGPs and unfortunately, it doesn't work the same as the discrete cards, so for now we should disable it. The attached patch should do the trick. There weren't any problems on my IGP chips, but they don't have a SetVoltage table, so nothing is touching the hw. I'm not sure if the adapter is a discrete one. Anyway, my testing was done before commit 386f40c86d6c8d5b717ef20620af1a750d0dacb4 and I'm unable to reproduce the problems with current -git, so they might be a fallout of the bug fixed by that commit.

I'm afraid it's too late, the patch has been merged. The fact that two OEMs have changed the vendor ID makes it likely that this is a bug in AMD's template BIOS code, and that we will see the same problem on other systems using other vendor IDs. So we should not use the vendor ID of device 0x9602 to declare the quirk, but use some other device with an ID that is known to be correct. We already access the configuration space of the host bridge, so we should use that. Furthermore, the quirk in my first patch was never run at all on the ALi system, so it is probable that the nb_cntl.strap_msi_enable detection would actually work. Rafael, please test this patch; if it doesn't work on your system, we can still remove the check for the strap_msi_enable bit. == Subject: PCI quirk: RS780/RS880: work around wrong vendor IDs of RS780 bridge On many RS780 systems, the vendor ID of the PCI/PCI bridge for the internal graphics is set to that of the mainboard vendor, so the quirk would not match and failed to notice the disabled MSI. Since we do not know in advance all possible vendor IDs, we have to declare the quirk on another device with an ID that is known to be correct, and use that as a stepping stone to find the PCI/PCI bridge, if present.

[ Side note: somebody in the DRM tree seems to be way too used to LISP,
and thinks that adding parenthesis always improves the code ;-]
However, I do suspect that we should probably revert the quirk regardless
as being useless (ie it probably was related to those IGP chips that
apparently don't do MSI anyway).
So the patch that reverts the quirk by Clemens (to replace it with
disabling MSI entirely when the AMD NB doesn't accept them) seems to be a
good idea regardless, since it's apparently not just about gfx. Jesse?
Yeah, that sounds fine. I can include it in my next pull req or you
can just pick it up directly.
Not exactly that one, please, it's missing a quirk for the affected system.
I've just sent a corrected version, here:

Subject: DRM / radeon: Really do not try to enable MSI on RS780 and RS880
Commit a5ee4eb75413c145334c30e43f1af9875dad6fd7
(PCI quirk: RS780/RS880: work around missing MSI initialization)
removed a quirk to disable MSI on RS780 and RS880, which still is
necessary on my Acer Ferrari One, because pci_enable_msi() attempts
to enable the MSI and apparently succeeds despite the PCI quirk
added by that commit. Add the removed radeon quirk again.

Resume problem with radeon+KMS (2.6.34-rc2 and before)
Hi, Some time ago I reported a problem with resuming from suspend to RAM on HP nx6325 with radeon+KMS. The problem was that the first resume always failed if the suspend was started from under X. Moreover, the resume went correctly until the last switch from the framebuffer console (which was now controlled by the radeon driver as well) to X that made the box hang hard. However, if the first resume was started from the (radeon-controlled) framebuffer console, the subsequent resume succeeded and all of the next attempts to suspend/resume succeeded, _regardless_ of the way the suspend was started. At that time Dave thought it might be a problem with the nx6325's graphics adapter that apparently was a crappy one, but today I found that _exactly_ the same behavior was observable on Acer Ferrari One, which was quite different, hardware-wise, from the old HP box. For this reason I think the problem is related to the driver itself rather than to the hardware or firmware. The problem is reproducible on both machines with the latest git kernel and the user space radeon_drv.so from openSUSE 11.2 (it says module version = 6.12.4 in the X log). The kernel and user space are 64-bit on both machines. [For completness, the Acer box suspends and resumes correctly with radeon.modeset=0 and s2ram -f -p -m.] Should I try a newer user space X driver? Or may the problem be related to the 64-bitness somehow? Rafael -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Re: i915 lockup / extreme delay
[Adding CCs] On Saturday 20 March 2010, Karl Vogel wrote: I have been experiencing a very sluggish X server right after starting my laptop. The effect goes away after a few minutes, so it was rather hard to track down. Recently after updating WINE to a newer release, I've been able to trigger the effect by running a certain game under wine on a remote computer and using VirtualGL to transport the GL display to my laptop. As I first thought the issue was somewhere with wine/virtualgl, I posted the question to the virtualgl mailing list. The thread is here: http://thread.gmane.org/gmane.comp.video.opengl.virtualgl.user/170 But after some further investigation, it seems the issue is with the i915 driver. The 'effect' is that only the mouse pointer works in the X server. The cpu usage on the laptop during the sluggishness is minimal.

Re: [Bisected Regression in 2.6.32.8] i915 with KMS enabled causes memorycorruption when resuming from suspend-to-disk

Vefa Bicakci wrote: Hello, As you can guess from the subject, I have noticed that enabling the KMS feature of the i915 module with any kernel version after 2.6.32.7 causes memory corruption after one resumes from suspend-to-disk. My hardware is a Toshiba Satellite A100, with an Intel graphics card. I am using an up-to-date version of Debian Sid. Here are the lspci entries for my graphics card: === 8 === 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03) (prog-if 00 [VGA controller]) 00:02.1 Display controller [0380]: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller [8086:27a6] (rev 03) === 8 === I have noticed that after upgrading from 2.6.32.7 to 2.6.32.9, I started to get a lot of segfaults from different programs when I resume from suspend-to-disk. After searching the Internet for this problem, I have seen that some other people also had it, and that it wasn't a new problem either: http://bbs.archlinux.org/viewtopic.php?id=91375 https://bugzilla.redhat.com/show_bug.cgi?id=537494 http://bugzilla.kernel.org/show_bug.cgi?id=13811 Even though some people say that they have had this problem for a long time, I have only noticed it after upgrading to 2.6.32.9. After booting with nomodeset and confirming that the problem doesn't happen with that kernel option, I have determined that the problem was with i915. Then I used the following command to bisect the changes that i915 has seen between 2.6.32.7 and 2.6.32.9: git bisect start v2.6.32.9 v2.6.32.7 -- ./drivers/gpu/drm/ With each iteration in the bisection, I have tried at least 3 cycles of suspend-to-disk and resume operations. I saw that all of the tried versions had memory corruption issues after resume from suspend-to-disk. Then, git told me that the culprit is the first change to i915 after the release 2.6.32.7. So 2.6.32.8 introduced the regression I am experiencing. Here's the git bisect log output: === 8 === # bad: [7f5e918e62cbc9ac27c2f47d3c3dd4b86f67ff0e] Linux 2.6.32.9 # good: [b4bdd73ce865213a5653dc424873e8da37e858cc] Linux 2.6.32.7 git bisect start 'v2.6.32.9' 'v2.6.32.7' '--' './drivers/gpu/drm/' # bad: [192ff23a2206eb5136c779bfed73171a4d214ad6] drm/i915: Add HP nx9020/SamsungSX20S to ACPI LID quirk list git bisect bad 192ff23a2206eb5136c779bfed73171a4d214ad6 # bad: [6240058ce3725f5e708e1c17c3a676217e44ba9b] drm/i915: disable hotplug detect before Ironlake CRT detect git bisect bad 6240058ce3725f5e708e1c17c3a676217e44ba9b # bad: [61d4374b51386dd40c03fd15df5a7f97347de688] drm/i915: Reload hangcheck timer too for Ironlake git bisect bad 61d4374b51386dd40c03fd15df5a7f97347de688 # bad: [d8e0902806c0bd2ccc4f6a267ff52565a3ec933b] drm/i915: Selectively enable self-reclaim git bisect bad d8e0902806c0bd2ccc4f6a267ff52565a3ec933b d8e0902806c0bd2ccc4f6a267ff52565a3ec933b is the first bad commit commit d8e0902806c0bd2ccc4f6a267ff52565a3ec933b Author: Chris Wilson ch...@chris-wilson.co.uk Date: Wed Jan 27 13:36:32 2010 + drm/i915: Selectively enable self-reclaim commit 4bdadb9785696439c6e2b3efe34aa76df1149c83 upstream.

So I am not sure if the commit above causes the bug or if it makes the bug easier to trigger. Finally, I would like to note that this regression is going to be important, because, as you know, Intel's X11 drivers are not going to support mode-setting in user mode starting with version 2.10.0. If there is any help I can provide in fixing this regression, please let me know. I am willing to try patches.

I guess that would require some detailed debugging, so it may be a good idea to open a Bugzilla entry for this issue. ... I was wrong (don't know why). Writing PS2K does indeed enable both. And sure enough, doing that allows the system to wake up in response to a key press. It still hangs during the video resume, though. Why are the values independent from the wakeup settings in sysfs? Aren't they supposed to mean the same thing? Not really. There are two separate flags for wakeup. One of them is a property of the physical device object (eg. PCI device structure) and that one is set/unset via sysfs. The other is a property of the device's ACPI shadow object and is set/unset through /proc/acpi/wakeup (this mechanism is regarded as obsolete, but it looks like some devices have not been converted to the sysfs-based one yet). It looks like the inline routines defined in include/linux/pm_wakeup.h should call corresponding platform-specific routines. Apparently _no_ drivers have been converted in this way -- since the conversion needs to be part of the core. In fact, there isn't even a platform-specific hook for enabling or disabling wakeup devices; we should have a platform_wakeup_ops structure. There is one for PCI devices, actually. It's struct pci_platform_pm_ops() defined in drivers/pci/pci.h. For PCI devices we have pci_enable_wake() that sets up the platform to wake up the system using given device on the basis of the device's sysfs setting. The ACPI flag shown by /proc/acpi/wakeup is not taken into account in that case. Generally, you can think of two levels one can enable wakeup at. First, there is the device level controlled by the sysfs wakeup setting. This is how we would like to control wakeup. Second, however, there is the /proc/acpi/wakeup interface allowing you to access the _internal_ ACPI representation of devices directly and you can use that to set up the platform to use the device for wakeup even if the device level mechanism doesn't work or is not implemented for it (like in your case). IOW, the /proc/acpi/wakeup thing only tells us if the device is forced to do the wakeup at the low level and it only takes the ACPI aspect of the wakeup into account, which may not be sufficient. For exmaple, network adapters (and other PCI devices) generally need to have the PME signaling enabled in addition to the platform setup and the chip has to be enabled to take wakeup packets from the network. If /proc/acpi/wakeup shows enabled this means turn on the wakeup power for this devices and enable its wakeup GPE unconditionally before suspend. If it shows disabled, it means leave that to someone else (that's analogous to the on and auto settings for devices/.../power/control, but the names are misleading for historical reasons). So, it looks like we need a counterpart of pci_enable_wake() for PNP devices. I guess it's better to invite Dmitry into the discussion at this point.

The ACPI flag shown by /proc/acpi/wakeup is not taken into account in that case. That's not what I meant. Writing to /sys/devices/.../power/wakeup should have the same effect as writing to /proc/acpi/wakeup (if the device has a shadow ACPI counterpart, of course). That really is not worth it. The information about the sharing of a GPE is only useful for debugging purposes and only in really broken cases. It looks like /proc/acpi/wakeup does nothing but set acpidev-wakeup.state.enabled and warn about duplicate GPE usage. That's correct, although the warning itself doesn't really make sense, because the sharing of the GPE doesn't mean we _have_ _to_ enable both devices to wake up (the devices usually require some more preparations than just setting the GPE). It would make sense to issue the warning when writing to the sysfs file. That's not worth the added code complexity IMO. And wakeup.state.enabled shouldn't be needed at all; Right, but it was there before. the ACPI code should always use the physical device's may_wakeup flag instead (unless there is no corresponding physical device). No, it shouldn't, because it doesn't know if the device has actually been set up for wakeup at its bus type level. If writes to the sysfs file called a platform hook, we could warn about duplicate GPEs when the wakeup setting is changed. As I wrote above, this is not worth it IMO. Moreover, that doesn't really matter, because the GPEs will be enabled as needed anyway and there's no real need to tell the user which of them are shared except for debugging (at the fairly low level). Furthermore, the GPE refrence counting code we're going to add shortly changes that quite a bit. Generally speaking, I'd like to get rid of /proc/acpi/wakeup altogether or maybe leave it as read-only without the disabled/enabled column. However, there still are devices that don't have an alternative mechanism for enabling wakeup, so we can't just drop it right now.

Hi,
commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash
while aborting hibernation) introduced two new issues which were not
present in 2.6.33-rc7:
- every second resume from hibernate results in a blank screen
- the annoying flash at the end of atomic copy/restore during the
hibernate process is back (present in kernels 2.6.33)
The first issue is serious, the second is just an annoyance.
The second one is an expected price of fixing the aborted hibernation
regression.
The first one shouldn't happen, though.
I'll see if I can reproduce that locally.
No, I can't.
Is the driver compiled directly into the kernel or modular?
The driver is modular.
And sorry, I forgot to tell you I'm using TuxOnIce, it certainly makes
a difference.
It shouldn't in fact, although I'm not sure.
However, every since I reverted that commit I've done 10 test
hibernations and no hang so far.
First, please try if you can reproduce it with non-modular driver.
Second, please check if the appended patch helps.
Rafael

Subject: i915 / PM: Fix crash while aborting hibernation
From: Rafael J. Wysocki r...@sisk.pl
Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement
new pm ops for i915) introduced the problem that if s2disk
hibernation is aborted, the system will crash, because
i915_pm_freeze() does nothing, while it should at least reverse some
operations carried out by i915_suspend().
Fix this issue by splitting the i915 suspend into a freeze part a
suspend part, where the latter is not executed before creating a
hibernation image, and the i915 resume into a low-level resume
part and a thaw part, where the former is not executed after the
image has been created.

Re: [linux-pm] [regression] drm/i915: implement new pm ops disables irq on aborted s2disk
On Wednesday 03 February 2010, Alan Jenkins wrote: Hi I found this regression on my EeePC 701 with modesetting enabled. When I hibernate using s2disk, I can abort the hibernation by pressing the backspace key. Doing so breaks X on 2.6.32-rc6 (but not 2.6.32). Yeah. To be honest, I knew that's going to happen, but didn't have the time to take care of it. The problem is that i915 does literally _nothing_ in its .thaw() callback, although it should at least reverse whatever .freeze() did to the hardware (and memory allocations and so on), so that the adapter is functional after creating the image. Fixing this requires some thought, though, because at the moment .freeze() thinks it's .suspend(), which is not the case as this report clearly shows. So, in fact i915_pci_suspend() has to be split into the .freeze() part and the poweroff part cleanly and that's not so simple (at least to me). Hopefully I'll have some time to work on this during the weekend.

Judging by the quilt series¹, the patch is slated for submission after 2.6.33. This late in the game for .32, I'm guessing maybe a stable backport after .33 is out? I guess so. Thanks!

That would have to be done using suspend notifiers and should depend on what driver actually controls the screen at the moment. And I guess the only case in which we actually _need_ to do the kernel VT switch is when the hardware is controlled by X and without KMS. Is there a simple way to determine if that's the case?

There's no X yet or it's already exited, so we don't need a VT switch anyway. Also what happens if you have KMS and non KMS consoles both active through the frame buffer off different cards ?

[PATCH] PM / i915: Skip kernel VT switch during suspend/resume if KMS is used
From: Rafael J. Wysocki r...@sisk.pl
If a non-KMS graphics driver is used, the kernel carries out a VT
switch during suspend/resume to avoid possible problems with freezing
X at a wrong time and to cause X to repaint everything after resume.
This is not necessary any more if the KMS is used, so skip the kernel
VT switch during suspend/resume for i915 in the KMS mode.

Hi,
I've been testing this patch for over a week and haven't seen a single problem
related to it during this time.
Are there any objections to it?

[RFT/RFC] PM: Skip kernel VT switch during suspend/resume with i915/KMS drivers
Hi,
I've been experimenting with the appended patch for some time. It appears to
speed up suspend and resume a bit if the box uses i915 with KMS.
It doesn't seem to break things, but of course more testing would be
appreciated. Comments are welcome as well.
Thanks,
Rafael

I'm not even sure the Intel guys are taking stable seriously enough yet. So far I don't think there is one kernel release (even stable) that works on all Intel chipsets without backporting patches. 2.6.32 needs the changes to remove the messed up render clock hacks which should really have been reverted a lot earlier since we had a lot of regression reports. The number of users using powersave=0 to get anything approaching useable is growing etc. But you could apply that argument to the existing DRM code (not just Intel) as well; lots of things are broken or unimplemented and never get fixed. I'd say the right metric isn't whether regressions are introduced (usually due to new features) but whether the driver is better than the old userspace code. For Intel at least, I think we're already there. The quality of the kernel driver is higher and it has many more features than the userspace implementation ever did. That's just my subjective opinion, but I've done a *lot* of work on our bugs both in userspace and in the kernel, so I think it's an accurate statement. The problem is at any single point in time I'm not sure a kms kernel exists that works across all the Intel hw, which from a distro POV is a real pain in the ass, a regression gets fixed on one piece of hw just as another on a different piece gets introduced. I'd really like if Intel devs could either slow it down and do more testing before pushing to Linus, or be a lot quicker with the reverts when stuff is identified. The main thing is the render reclocking lately, thats been a nightmare and as far as I can see 2.6.32.3 still has all the issues, Hmm, are you trying to say radeon is better at that? My experience is quite the opposite to be honest.

(I think SuSE default to this for all cards r500). No I'm not. This isn't the driver that is developed by the opensource community and really your distro is where you complain about that sort of regression. I know, I'm not using it. The wierd thing is we see distro picking up fixes for userspace drivers *much* quicker if their teams are the on the ball since they are only a small component to upgrade, with the kernel you find most distro fire and forget, so if 2.6.31 doesn't work on your hw you'll wait 6 months to find out that 2.634 doesn't work either. Well, openSUSE upgrades the kernel to -stable quite timely. Which is not the case with the Xorg drivers, so apparently it depends which distro you are on. :-) Rafael -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
