Might be interesting to watch how this develops.
<neal> check this out: <neal> someone is working on implementing dbus in linux <neal> linux finally gets mach ipc ;-) <marcusb> it's old news though, unless there is an update <marcusb> and I think it was only the client? <neal> youpi : someone is adding dbus ipc to the linux kernel <neal> marcusb: I just heard about it. <youpi> (it's crazy how this drives backward compared to a hurdish approach) <youpi> what is the motivation for moving to the kernel? <neal> context switch overhead <azeem_> they wanna use it to talk to device drivers? :) <kilobug> well, they did that with the in-kernel web server, but they abandonned it later on <neal> azeem: I don't think so. <neal> dbus in the kernel is actually good for the Hurd as dbus IPC is basically neutered Mach IPC <marcusb> I don't think anybody wants to put the dbus server in the kernel <neal> well, there is at least one person <marcusb> maybe this is a different news from the one I read <neal> Alban Crequy (albanc) is working out. He works for collabora, fwiw
<marcusb> what I read was about hal etc <marcusb> so that you don't need a user space daemon to glue the kernel to the dbus world <neal> I don't think that is what he is talking about <marcusb> I can't find it anymore though. I mentioned it in this channel at the time though, so it should be in the backlog <marcusb> neal, yeah could very well be a separate thing <marcusb> neal, dbus does have marginal support for fd passing though, and some attempts on the mailing list to make "fds" an official type in the message failed (as far as I could see, I didn't read the whole discussion) <marcusb> so no mach ipc just yet <neal> wrong <neal> FD handling is in 1.4 <neal> type o, if I'm not mistaken <marcusb> then the discussion moved on from initial rejection <neal> no, 'h' <marcusb> I'm out of date by two months <marcusb> ok <guillem> neal: AFAIR Marcel Holtmann talked about dbus in-kernel several years ago, but he never ended up implementing it, or there were rumors he had private "working code"
