https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #15 from Bc. Slavomir Danas 2011-01-16 19:45:49 --- I've had this drm_kms_helper.poll=N kernel workaround in my grub since I've discovered it in 18802 bug (around 2.6.36-r2 i think) because I've suffered by the udev drm polling storm in 2.6.34, kslowd in 2.6.35 and kworker in 2.6.36. Since I've applied it everything was working smooth. I read the announcement about bug 18802 being duplicate of this bug and it being resolved as of 2.6.36-rc5 so I have removed this kernel setting and rebooted with my 2.6.37 kernel hoping that everything should be fine. But in few minutes the same symptoms appeared so I reverted back to drm_kms_helper.poll=N kernel option and everything seems all right again (with the workaround). I can provide more info on my HW or SW by request. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #16 from Chris Wilson 2011-01-16 22:46:41 --- You need to quantify your observations here. When polling is enabled, then every 10s the worker will be awoken and consume CPU time checking that all the displays are the same as before. Unless on your machine it takes a ridiculous amount of CPU time (say greater than 5%), it is just the cost of the ability for your computer to automatically detect display changes. The real bug is the latency it induces...

Slavomir Danas 2011-01-18 18:18:36 --- It doesn't seem to me as sane to consume this amount of CPU time to poll for anything (see attached screenshot). I figured a way how to reproduce this, I've enabled RandR polling in KDE, attached LCD TV via HDMI and played a video in VLC. After few mouse clicks in the menu of VLC I've witnessed jerky mouse movement and later my X has frozen completely. I've switched to console and found out that when I unpluged HDMI the kworker process went quiet. I was able to take one screenshot but as my X froze I saw 3 kworker processes running, eating all CPU time rendering my system useless (no chance to take screenshot at that moment).

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #15 from Bc. Slavomir Danas 2011-01-16 19:45:49 --- I've had this drm_kms_helper.poll=N kernel workaround in my grub since I've discovered it in 18802 bug (around 2.6.36-r2 i think) because I've suffered by the udev drm polling storm in 2.6.34, kslowd in 2.6.35 and kworker in 2.6.36. Since I've applied it everything was working smooth. I read the announcement about bug 18802 being duplicate of this bug and it being resolved as of 2.6.36-rc5 so I have removed this kernel setting and rebooted with my 2.6.37 kernel hoping that everything should be fine. But in few minutes the same symptoms appeared so I reverted back to drm_kms_helper.poll=N kernel option and everything seems all right again (with the workaround).

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #16 from Chris Wilson 2011-01-16 22:46:41 --- You need to quantify your observations here. When polling is enabled, then every 10s the worker will be awoken and consume CPU time checking that all the displays are the same as before. Unless on your machine it takes a ridiculous amount of CPU time (say greater than 5%), it is just the cost of the ability for your computer to automatically detect display changes. The real bug is the latency it induces...

Slavomir Danas 2011-01-18 18:18:36 --- It doesn't seem to me as sane to consume this amount of CPU time to poll for anything (see attached screenshot). I figured a way how to reproduce this, I've enabled RandR polling in KDE, attached LCD TV via HDMI and played a video in VLC. After few mouse clicks in the menu of VLC I've witnessed jerky mouse movement and later my X has frozen completely. I've switched to console and found out that when I unpluged HDMI the kworker process went quiet. I was able to take one screenshot but as my X froze I saw 3 kworker processes running, eating all CPU time rendering my system useless (no chance to take screenshot at that moment).

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #15 from Bc. Slavomir Danas 2011-01-16 19:45:49 --- I've had this drm_kms_helper.poll=N kernel workaround in my grub since I've discovered it in 18802 bug (around 2.6.36-r2 i think) because I've suffered by the udev drm polling storm in 2.6.34, kslowd in 2.6.35 and kworker in 2.6.36. Since I've applied it everything was working smooth. I read the announcement about bug 18802 being duplicate of this bug and it being resolved as of 2.6.36-rc5 so I have removed this kernel setting and rebooted with my 2.6.37 kernel hoping that everything should be fine. But in few minutes the same symptoms appeared so I reverted back to drm_kms_helper.poll=N kernel option and everything seems all right again (with the workaround). I can provide more info on my HW or SW by request. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #16 from Chris Wilson 2011-01-16 22:46:41 --- You need to quantify your observations here. When polling is enabled, then every 10s the worker will be awoken and consume CPU time checking that all the displays are the same as before. Unless on your machine it takes a ridiculous amount of CPU time (say greater than 5%), it is just the cost of the ability for your computer to automatically detect display changes. The real bug is the latency it induces...

Slavomir Danas 2011-01-18 18:18:36 --- It doesn't seem to me as sane to consume this amount of CPU time to poll for anything (see attached screenshot). I figured a way how to reproduce this, I've enabled RandR polling in KDE, attached LCD TV via HDMI and played a video in VLC. After few mouse clicks in the menu of VLC I've witnessed jerky mouse movement and later my X has frozen completely. I've switched to console and found out that when I unpluged HDMI the kworker process went quiet. I was able to take one screenshot but as my X froze I saw 3 kworker processes running, eating all CPU time rendering my system useless (no chance to take screenshot at that moment).

Did you mean with that, that the problem is in 2.6.37 (final) still present and only solved by putting drm_kms_helper.poll=N on the commandline... or Even with polling disabled via the commandline drm_kms_helper.poll=N you experience the symptoms?

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #15 from Bc. Slavomir Danas 2011-01-16 19:45:49 --- I've had this drm_kms_helper.poll=N kernel workaround in my grub since I've discovered it in 18802 bug (around 2.6.36-r2 i think) because I've suffered by the udev drm polling storm in 2.6.34, kslowd in 2.6.35 and kworker in 2.6.36. Since I've applied it everything was working smooth. I read the announcement about bug 18802 being duplicate of this bug and it being resolved as of 2.6.36-rc5 so I have removed this kernel setting and rebooted with my 2.6.37 kernel hoping that everything should be fine. But in few minutes the same symptoms appeared so I reverted back to drm_kms_helper.poll=N kernel option and everything seems all right again (with the workaround). I can provide more info on my HW or SW by request. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #16 from Chris Wilson 2011-01-16 22:46:41 --- You need to quantify your observations here. When polling is enabled, then every 10s the worker will be awoken and consume CPU time checking that all the displays are the same as before. Unless on your machine it takes a ridiculous amount of CPU time (say greater than 5%), it is just the cost of the ability for your computer to automatically detect display changes. The real bug is the latency it induces...

https://bugzilla.kernel.org/show_bug.cgi?id=16265 --- Comment #17 from Bc. Slavomir Danas 2011-01-18 18:18:36 --- It doesn't seem to me as sane to consume this amount of CPU time to poll for anything (see attached screenshot). I figured a way how to reproduce this, I've enabled RandR polling in KDE, attached LCD TV via HDMI and played a video in VLC. After few mouse clicks in the menu of VLC I've witnessed jerky mouse movement and later my X has frozen completely. I've switched to console and found out that when I unpluged HDMI the kworker process went quiet. I was able to take one screenshot but as my X froze I saw 3 kworker processes running, eating all CPU time rendering my system useless (no chance to take screenshot at that moment). I repeat I'm running latest gentoo-sources-2.6.37. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
