I don't quite understand the need, want, or mechanism for this. For high performance or VR systems where context switch overhead would be too much (and I don't believe this, since they tend to use separate acceleration chips for real-time work), the answer would not be to move from userspace to the kernel -- kernel threads are like any other and have context switch penalties. If you have real performance issues with Wayland's architecture, let's discuss that and try to solve it. There's probably a lot there that's slow, but I doubt context switches are the bottleneck. <div class="gmail_quote"><div dir="ltr">On Wed, Dec 30, 2015, 11:56 AM <<a href="mailto:me@beroal.in.ua">me@beroal.in.ua</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi.

This is what I prefer because mathematical definitions are precise. Philosophical definitions are not, so reasoning with them does no good. _______________________________________________ wayland-devel mailing list <a href="mailto:wayland-devel@lists.freedesktop.org" target="_blank">wayland-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/wayland-devel" rel="noreferrer" target="_blank">http://lists.freedesktop.org/mailman/listinfo/wayland-devel</a> </blockquote></div>
