The biggest change I'm expecting in 3.2 is a bug > fix to the old (non-kernel) PPS code. > While there are several packages in openwrt head that pull directly from a git commit of a given package, I would personally prefer that gpsd 3.x baked a little more (with people testing on arm, mips, mobile devices, etc) and I am also hoping However, I note that I am not in any way a gatekeeper to the main openwrt feeds. Their requirements are different. We (bufferbloat.net) spun up ceropackages specifically to enable those newer to openwrt development and embedded development to be able to use github as a base, and 'screw up' freely while mastering the cross-development process, while not necessarily being able to do builds on or for their own hardware. Well, that, plus we wanted to try out some crazy things like a variety of new test tools, multicast routing, using xinetd, etc. A side goal is to get the developers of a given piece of software's heads around how different embedded development can be, and also get needed patches pushed up into those mainline packages. It has been fun getting evan hunt (bind9 maintainer at isc.org) and your respective heads around life inside 8MB of flash. > I note that you will have to install the right kmod-serial-* to > get the right kernel support for your specific device, Bu "your specific device" you mean the router hardware?

(I'm documenting this for your future builds) I note many openwrt based devices have real serial ports, too. The wndr actually has one inside it that can be hacked onto. I note that adding a kmod-usb-serial-* depenendency to the gpsd package is the wrong thing, as openwrt is more like a 'distro to build hardware' distro, where the designer of the firmware would pick and choose the right kernel modules for their particular hardware. saving any and all space on precious flash is in large part what drives packaging for embedded firmware, which is why I'd like to nuke the gpsd libusb dependency as it's only for one rarely used device. > and enabling the -G > > option to gpsd allows you to contact the router remotely with tools like > > cgpsd, etc. > > I've added a force_global configuration option to force -G on for > deployments > like CeroWrt where listening only on loopback is not a good idea. > Well... then it needs to be invertible somehow. And the gpsd openwrt package could merely have an option in the gpsd.config file to enable it where needed. I can certainly see cases where lo can be used by other apps on the router and no other access is needed. That said, full ipv6 support would be nice, too. > -- > <a href="http://www.catb.org/~esr/";>Eric S. Raymond</a> > -- Dave Täht SKYPE: davetaht US Tel: 1-239-829-5608 http://the-edge.blogspot.com
