~ (reposting from webkit email) Hello! I suggest starting by learning one of the other ports - like GTK - how the whole flow works from the windowing system to WebCore to the graphics system. Read the code, run it in debug mode and put breakpoints, get those aha moments of how it all works together.
Note that coordinated graphics is not automatically the right choice for every port - it was created for mobile windowing systems where window context-switching was expensive and single-context hardware acceleration was cheap. If you're looking for a guide check out https://trac.webkit.org/wiki/CoordinatedGraphicsSystem, hopefully it's still somewhat valid. I would start there by understanding the flow and how it fits with the Haiku architecture, seems like you've started doing that already. you're on the right track there. btw I might be able to help out (no promises), I haven't touched WebKit code in a few years but I was responsible for TextureMapper and the coordinated graphics system and I like bizarre projects (a Haiku port sounds like one). Let's see how it goes :) On Mon, Jun 10, 2019 at 9:05 AM Rajagopalan Gangadharan < g.raju2...@gmail.com> wrote: > Hello everybody, > > A quick look back on what we have done so far.
