V3.17 and earlier kernels run like champs. These greetings are independent of Mesa (versions 9.2.5 - 10.3.2), xf86-video-intel (any up to and including 2.99.916), libdrm up to and including v2.4.58, as well as other boards utilizing the i915 driver. I use the Gallium driver as I need OpenGL V2 support - I can't begin to express my gratefulness for the Gallium driver.

I have not tested with an OpenGL v1.4 driver yet. Enclosed is the kernel .config file common to all kernels using Intel embedded graphics. This kernel (3.18 rc2) also introduces performance issues after the warning and eventually hangs with no message or trace. rc1 continues to run and does not hang. Sorry, I'm unable to give more info as I am on the road - I continue to receive my mail though.

I donate my time in the Philippines teaching all ages computer science and as such I can only afford used hardware, or computers that are donated, in my classes. My newest machine (except my personal) is a core 2 processor. (LGA775 socketed motherboards.)

Besy regards,

Jim McDevitt

You haven't mentioned an actual hang?

I said "This kernel (3.18 rc2) also introduces performance issues
after the warning and eventually hangs with no message or trace. rc1
continues to run and does not hang." rc2 and rc3 hangs - I cannot get
to the debug file system even to get any file. The machine is quite
locked up I have to hard reset. Same behavior on an asus board as well
as the Elite (what a misnomer that is)
Comment 4 Mika Kuoppala 2014-11-06 12:04:04 UTC
Jim, could you please try with i915.use_mmio_flip=1 if it makes a difference?
Comment 5 Jim 2014-11-07 22:23:21 UTC
Looks like that did the trick. Thanks much.

I also have the same hang on playing videos or graphic operations.

use_mmio_flip=1 makes no difference

I have bisected it to
d6bbafa183793537d8dca4d4c2e448805e59448a
drm/i915: Check for a stalled page flip after each vblank
and
9c787942907face82da505c2c5493998b56cfc5a
drm/i915: Decouple the stuck pageflip on modeset

Reverting these commits restores trouble free operation.

The trouble starts in i915_handle_vblank, I am just reverting just the changes made to this function for now.

I tried just in case I missed something but that was to no avail. I think I've got it down to 3 commits, but it is a little more complicated than that.

Thanks for the post! It's really annoying.

Comment 12 Jim 2014-11-21 01:52:26 UTC
I'm sorry, I already tried that to no avail. Same problem. I didn't think that was the issue as everything points to the batch of drm changes pushed in 3.18-rc1. I will have the bisection by Sunday.

    drm/i915: Ignore SURFLIVE and flip counter when the GPU gets reset
Comment 14 Malcolm 2014-11-21 17:59:16 UTC
Unfortunately the latest drm-intel-fixes does not resolve the issue. Although I do get a little longer before the machines dies after the Kicking stuck page flip warning.

Just for clarification I am using the Intel® 946GZ chip set.

Just one query in __intel_pageflip_stall_check the kick always happens on
if (atomic_read(&work->pending) >= INTEL_FLIP_COMPLETE)

*work->pending == INTEL_FLIP_COMPLETE(2) is this correct?

I am confused as to whether it going complete or has it completed?

and how could advance beyond INTEL_FLIP_COMPLETE(2)?
Comment 15 Malcolm 2014-11-21 18:56:29 UTC
ignore my last questions, I have kinda worked it out now.
Comment 16 Jim 2014-11-22 04:06:49 UTC
Bisect in early - promised son Sunday.

I am now fairly befuddled. I did this process on three machines. On the twin of this motherboard, a student did the bisection manually. On the machine I reported I wrote a script to try all possible combinations of what was pushed in rc1. When I came back to check, result was inconclusive. So. I looked a little more closely to the patch Malcolm suggested (by itself, it didn't solve my problem.)

Maybe my machines have different timings and maybe rc1 just exposed what was there all along. I then re-applied Malcolms' patch and re-ran my script. What it spit out was commit f0d3dad3. Lo and behold no more problem. The patch description:

   Author: Chris Wilson <chris@chris-wilson.co.uk>
   Date:   Sun Sep 7 16:51:12 2014 +0100

       drm/i915: Wrap -EIO send-vblank event for failed pageflip in spinlock
    
       drm_send_vblank_event() demands that we hold the event spinlock whilst
       calling it, so do so.
 
Looking at the code tells me this can't be the problem. I then extracted a fresh archive of rc1 and rc5 applied Malcolms' patch and reversed f0d3dad3. I rebuilt the entire kernel for both rc1 and rc5. No problems. If i do not revert f0d3dad3, I have the problem again. I installed the new rc1 kernel and also tried the rc5 kernel. Both were fine. I ran piglit and no problems except the the tests that always fail. So now, all 3 machines are happy.

All I want now is for somebody to explain to me WHY.

Thank you Malcolm for pointing me in the right direction.

create stuck_page_flip_completed to complete stuck flips

Try this patch it enables vblank_disable_immediate while the kick is in progress.

I have been running this patch for 4 hours now and the system hasn't hung.

I doesn't stop the warning message.
Comment 18 Malcolm 2014-11-23 00:40:57 UTC
Spoke too soon the patch failed:-(
Comment 19 Jim 2014-11-25 01:45:44 UTC
Just an update - 3.18-rc6 same story. Problem occurs with no patches installed, with just Malcoms' patch only, and with only commit f0d3dad3 reversed.

Trouble free with Malcolms' patch and commit f0d3dad3 reversed.

Looks like I should educate myself a bit more - some of the code I see is very hard to follow and sometimes I wonder what in the hell was that?

I'm an old microcoder and OS hacker; I never really had to get too involved with the graphics side of it.

Comment 23 Malcolm 2014-12-17 14:34:48 UTC
That patch failed.

It is clear the code is trying to kick a page that is not stuck but delayed.

This locks on call drm_crtc_vblank_put and the precise timing vblank->disable_timer completion.

This could be the new gen3/4 GPU reset handling. Any GPU hangs mentioned in dmesg?

It seems this is a separate issue, please file new bugs for new issues. Thanks.

Same here, applying the patch on the failing 3.19-rc3 fixes the problem for me too and confirms bug 86849 as a duplicate.

I have this on 3.19 final (git.freedesktop.org revision 89271faca1 compiled on 21-Feb 2015). It happened when resuming from S4 hibernation on a MSI MS-7817/CSM-B85M-E45 (MS-7817), BIOS V10.8 12/11/2014.

No, you have an entirely different issue. Please file a new bug.
Comment 36 Jens 2015-02-24 22:26:50 UTC
OK, will do. Sorry.

(How can you tell? I'm asking so I can tell before posting in the future.)
