* udev: avoid autosuspend of USB input devicesNitin A Kamble2013-09-171-0/+25
| | | | | | | | | | | | | | | | | | | | | | Some of the external USB devices has internal USB hub, which make them look like "fixed" rather than "removable". And USB autosuspend does not work with some of these devices resulting in inoperable pointing device. Now the code detect these false "fixed" devices by looking at their parents. If any of their parent is "removable", then USB autosuspend is not enabled for that device, which keeps the pointing device functional.

* udev: remove implicit dependency on initscriptsChen Qi2013-08-161-4/+12
| | | | | | | | | | | | | | | | | | At some point, the udev was modified to source the functions from initscripts or lsbinitscripts. This dependency is actually not needed. If we use udev in a system where initscripts from oe-core is not available, there will be errors. This patch fixes this problem by removing the implicit dependency.

* udev-cache: take a read-only rootfs into considerationChen Qi2013-07-022-22/+38
| | | | | | | | | | | | | | | | | | | | | | In case of a read-only rootfs, we skip the process of generating udev cache, as the data cannot be persisted between reboots. However, it's possbile that the $DEVCACHE (default to /etc/dev.tar) exists in a read-only rootfs, no matter how it's generated or installed. In such situation, we try to use $DEVCACHE if possible. Besides the basic changes in the logic of udev cache handling, this patch also adds code to output more information if the udev cache is not used and VERBOSE enabled. This patch also changes the readfile function to readfiles function so that it could handle more than one file at once.

* udev: only use devtmpfs for udevAlex Olson2013-06-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Fix for bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=4632 Since udev 172, the 'mknod' logic was removed from udev. Yocto Dylan is now using udev 182. This means /dev is now required to be a devtmpfs filesystem (maintained by the kernel). If the root filesystem is a ramdisk, the kernel's auto-mount of /dev doesn't activate since there is no rootfs to actually mount... The bug causes an unusable system as /dev doesn't contain even basic nodes required to even get a login prompt. The Yocto udev/init script mounts tmpfs if it does not detect tmpfs or devtmpfs mounted at /dev. This appears to be outdated logic that is no longer correct. I believe the Yocto udev init script should be checking and mounting only 'devtmpfs' on dev.

* udev-cache: fix to use udev-cache correctlyChen Qi2013-06-252-4/+6
| | | | | | | | | | | | | | | | | | | Previouly, the udev-cache has no real effect even if it's installed into the system. The key problem here is that at first boot, the /etc/dev.tar is not present, thus resulting /dev/shm/udev.cache not created on first boot even if udev-cache is enabled. This patch fixes this problem. The /dev/shm/udev.cache will be created if necessary, that is, on first boot or when some part of the system is changed. In the latter case, the udev cache may not be valid.

* udev: do not create /var/volatile/run in init scriptJonathan Liu2013-05-291-1/+0
| | | | | | | | | | | | | | | | Previously in udev init, /var/volatile/run had to be created after mounting all tmpfs filesystems so that udevd can write to /var/run (a symbolic link to /var/volatile/run). This is because udev is started before populate-volatile.sh. Now that /var/run is a symbolic link to /run (a tmpfs filesystem), /var/volatile/run doesn't need to be created anymore.

* udev: create /var/volatile/tmp to avoid dead linkChen Qi2013-04-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | If it's not first boot, /tmp has already been symlinked to /var/volatile/tmp. But the udev service starts before populate-volatile.sh starts. This leads to a dead link at /tmp. As a result, trying to create any file under /tmp will fail. If a USB is plugged in before the populate-volatile.sh script starts, the /tmp/.automount-$name file will not be created correctly. As a result, when the USB is unplugged, the /media/$name directory is not removed. So we create /var/volatile/tmp directory in the udev script to avoid this dead link problem.

* udev: move /run volatile entry to udev instead of initscriptsRoss Burton2013-03-261-0/+1
| | | | | | | | | | | | | | | | initscripts is generally installed on systemd-using images, but because it specifies that /run is a symlink to /var/run managed by volatiles it totally breaks systemd by copying/deleting /run from underneath systemd. Deleting sockets mid-boot doesn't leave systemd in a happy place. As this volatile reference of /run was introduced by udev 182, move it's reference to the udev recipe. This way it will never be present on systemd images, as systemd manages /run as a tmpfs itself.

| | | | | | | | | | | | | | | | | | | | | | | | Since commit commit fbec192f6bc4 ("udev: Ensure tmpfs are mounted and volatile/run exists") all tmpfs-entries in fstab are mounted before udev starts using mount -a. If /dev/shm is among those entries, that mount will fail as the mount point has not yet been created: Starting udev mount: mounting tmpfs on /dev/shm failed: No such file or directory udevd[474]: starting version 182 Fix by restoring the old way of mounting /dev and mounting the remaining tmpfs-entries only after /dev/shm has been created. Also make sure that any errors are supressed for these tmpfs-mounts. Should any mount point not yet be present, that mount will be retried later during the boot process.

* udev: Ensure tmpfs are mounted and volatile/run existsRichard Purdie2012-10-301-3/+2
| | | | | | | | | | | | | | There is a race with udev where eiher the run directory can get replaced during bootup leading to ude errors, or if the tmpfs was mounted and populate-volatiles hasn't run, udev won't start at all. This ensures that any tmpfs get mounted before udev starts and that the default volatiles/run directory at least exists, fixing the races and boot time errors caused after the recent udev upgrade.
