[Kernel-packages] [Bug 1234743] Re: omapfb module floods system with udev events on samsung galaxy nexus
[Test case] 1. Install the updated package on an x86 system. 2. Reboot. 3. Confirm that the machine boots successfully. Check on Lenovo x220. Works OK. Passed. 4. Install the updated package on a non-maguro arm system. 5. Reboot. 6. Confirm that the machine boots successfully. Checked on LG Nexus 4. Works OK. Passed. 7. Install the updated package on a maguro system. 8. Reboot. 9. Confirm that the machine boots successfully. 10. Confirm using 'top' that udev is not taking up a significant percentage of the CPU time. Checked on Samsung Galaxy Nexus. udev is not busy, looks good to me.

[Kernel-packages] [Bug 1234743] Re: omapfb module floods system with udev events on samsung galaxy nexus
This patch adds netlink filter rules to ignore change events from omapfb if they are long enough to be a VSYNC event. It is a rather gross hack, I don't want to expect the VSYNC= at a specific place in the raw packet as the order or length of the other properties might change. But I verified that doing a manual echo change | tee /sys/devices/platform/omapfb/uevent still gets through, whereas the offending vsync events are now quiet and don't wake up anything any more. For testing, I ran my locally built udev with sudo stop udev, sudo ./systemd-udevd --daemon, started a monitor with ./udevadm monitor -e, and then: * screen activity now does not produce any omapfb change events any more. Tested remotely with starting and stopping messaging-app with start application APP_ID=messaging-app; sleep 5; pkill -e messaging- app * echo change | sudo tee /sys/devices/platform/omapfb/uevent shows that synthetic uevent on both the KERNEL and LIBUDEV netlink sources. Thanks to Omer for giving me ssh access to his maguro, which helped to shorten the turnaround time. This device was running with SurfaceFlinger, so for making triple sure another test should be done on Mir. ** Patch added: udev: filter omapfv VSYNC uevents from netfilter https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1234743/+attachment/3880060/+files/0031-ignore-omap-vsync.patch -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234743 Title: omapfb module floods system with udev events on samsung galaxy nexus Status in Upstart: Fix Released Status in “linux” package in Ubuntu: Invalid Status in “lxc-android-config” package in Ubuntu: In Progress Status in “powerd” package in Ubuntu: Fix Released Status in “systemd” package in Ubuntu: Fix Committed Bug description: Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct 2013) for 30 minutes I observed that init is busy and also consuming heap quite rapidly.

[Kernel-packages] [Bug 1234743] Re: omapfb module floods system with udev events on samsung galaxy nexus
Steve wanted a 0-day SRU with this so that we can build new phone images with that included. The way the patch is done is that it doesn't change anything on !arm; this both avoids potentially breaking i386/amd64/powerpc, and also avoids penalizing those platforms with the unnecessary extra netlink filter code. I uploaded it to unapproved to avoid blocking on that upload. But please feel free to reject if you would like the patch done in a different way, or some regression comes up during testing with the attached binaries. ** Changed in: systemd (Ubuntu) Importance: Undecided = High ** Changed in: systemd (Ubuntu) Status: In Progress = Fix Committed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234743 Title: omapfb module floods system with udev events on samsung galaxy nexus Status in Upstart: Fix Released Status in “linux” package in Ubuntu: Invalid Status in “lxc-android-config” package in Ubuntu: In Progress Status in “powerd” package in Ubuntu: Fix Released Status in “systemd” package in Ubuntu: Fix Committed Bug description: Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct 2013) for 30 minutes I observed that init is busy and also consuming heap quite rapidly.

Which appears to be getting a FD to kernel event source, via socket created by https://android.googlesource.com/platform/hardware/libhardware_legacy/+/android-4.3_r3/uevent/uevent.c so if we filter those VSYNC events on the udev source, systemd-udev upstart et al user space shouldn't be spammed with those and the driver will still work. Note, ideally we would already filter them at the kernel netlink source, so that udevd doesn't have to wake up 60 times a second. Filtering them at the libudev source would avoid waking up clients, but not udevd itself. However, that requires matching (kernel) properties in the netlink packet with only the rather limited set of instructions from http://www.gsp.com/cgi- bin/man.cgi?section=4topic=bpf#5 . I'll try that, but if it turns out to be impractical, I'll instead add a hack to at least short-circuit those in udevd, avoid all rules processing, and not forward them to the libudev netlink source. That'll keep the udevd wakeups but at least minimize the resources spent for each one. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234743 Title: omapfb module floods system with udev events on samsung galaxy nexus Status in Upstart: Fix Released Status in “linux” package in Ubuntu: Invalid Status in “lxc-android-config” package in Ubuntu: In Progress Status in “powerd” package in Ubuntu: Fix Released Status in “systemd” package in Ubuntu: In Progress Bug description: Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct 2013) for 30 minutes I observed that init is busy and also consuming heap quite rapidly.

Enabling Mir with VSYNC disabled in the omapfb driver leaves me in a state with just a blank screen.

[Kernel-packages] [Bug 1234743] Re: omapfb module floods system with udev events on samsung galaxy nexus when playing mp4
After some digging I've found the following: 1. commit a4e449e8a08e727b8160cb4e4a0367c447148d2f enables drivers/video/omap2/omapfb/omapfb-main.c to send VSYNC uevents on each vsync. 2. hwcomposer.omap4.so handles this VSYNC event, and inspecting /proc/$pid/maps it appears this is used by surface flinger. 3. reverting this commit does indeed reduce the events as received by init, however, surface flinger runs incredibly slowly as it does not get the vsync events. Since this is a tight coupling between an Android H/W abstraction and the kernel driver, I'm not sure how we progress on this. I don't have the know-how on hwcomposer to figure out how to decouple this. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234743 Title: omapfb module floods system with udev events on samsung galaxy nexus when playing mp4 Status in “linux” package in Ubuntu: Incomplete Bug description: Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct 2013) for 30 minutes I observed that init is busy and also consuming heap quite rapidly.

I suppose this is a driver that would still be in the picture when switching to Mir, and we can't hope to avoid the issue by changing display servers?
