#tizen EFL slide at Collaboration Summit 2012 https://t.co/69hF8GST

koba @tetsu_koba

#tizen Why is EFL being used as opposed to GTK+ or Qt or something else? ● Speed

koba @tetsu_koba

#tizen – Samsung used GTK+, X11 and DirectFB (in combinations) and once EFL was tried, it soundly beat these hands-down in performance

koba @tetsu_koba

#tizen Why EFL? ● Memory (Ubuntu 11.04) beyond base X11 “failsafe” session – Unity – 168Mb – Enlightenment 0.17 – 65Mb

koba @tetsu_koba

#tizen EFL: Multiple output paths ● X11 (OpenGL, Xlib & XCB) ● Wayland (OpenGL & SHM) ● Raw Framebuffer

X window systemの有力な後継。 / “Wayland” http://t.co/Y3uh8VLD

koba @tetsu_koba

Wayland with X11 compatibility: Wayland protocol librariesの上にWayland aware X server。X server can be started on-demand when X clients connect

koba @tetsu_koba

Wayland FAQ 「どうしてXを拡張する方法をとらなかった？」「Xは設計からして古い。」

koba @tetsu_koba

Wayland FAQ 「Wayland のプラットフォーム要件は?」「簡単に言えば、KMS と DRI driverがあればいい。」

koba @tetsu_koba

Wayland FAQ 「ネットワーク透過性は？」「server side renderingは無い。RDPや似たプロトコルでWestonのサーバのようなものを提供できるだろう。そしてそのほうが今のXよりずっと効果的だ。」

koba @tetsu_koba

Wayland schedule: 1.0, first stable release – Somewhere in first half of 2012 – Will include 1.0 of Weston compositor as well
