'Twas brillig, and Lennart Poettering at 17/07/11 02:33 did gyre and gimble: > Add support for multi-seat-aware input device hotplugging. This > implements the multi-seat scheme explained here: > > http://www.freedesktop.org/wiki/Software/systemd/multiseat > > This introduces a new X server switch "-seat" which allows configuration > of the seat to enumerate hotplugging devices on. If specified the value > of this parameter will also be exported as root window property Xorg_Seat. > > To properly support input hotplugging devices need to be tagged in udev > according to the seat they are on. Untagged devices are assumed to be on > the default seat "seat0". If no "-seat" parameter is passed only devices > on "seat0" are used. This means that the new scheme is perfectly > compatible with existing setups which have no tagged input devices. > > This also optimizes the udev code in away that is beneficial for systems > that do not support new udev/systemd style multi-seat: the patch makes > use of libudev functions to limit enumerating/monitoring of devices to > actual input devices. This should speed up start-up and minimize > wake-ups, since we will only enumerate/monitor the devices we are > interested in instead of all devices on the machine and all events they > generate. > > Finally, this also unifies the code paths for the udev "change" and > "add" events, since these should be handled the same way in order to be > robust to "udevadm trigger" calls, or lost netlink messages. This also > simplifies the code. > > Note that the -seat switch takes a completely generic identifier, and > that it has no effect on non-Linux systems. In fact, on other OSes a > completely different identifier scheme for seats could be used but still > be exposed with the Xorg_Seat and -seat. > > I tried to follow the coding style of the surrounding code blocks if > there was any one could follow.
I didn't see any feedback on this patch. Did anything more happen regarding it? Does it need a bug opened?
