Subject: [9front] /dev/draw performance
Date: Mon, 30 Nov 2020 08:03:53 +0000 [thread overview]
Message-ID: <BF74E0CB-15C1-4F9A-BC6D-B7D2F810A8B9@quintile.net> (raw)
quote: “The current windowing/graphics setup with /dev/draw as a kernel device and rio itself was implemented after Thompson, Ritchie, and Pike left Bell Labs and others thought the window system needed optimizing.”
This is not my memory.
work on plan9 switched to Brazil in 95, i believe it was seen as an experimental branch to try some major changes. the switch from 81/2 to rio and the new /dev/draw model was a major part of this. This was back ported to plan9 in time for the 3rd release in 2000 - just around the time many left the labs.
I am not saying rio cannot be improved, but characterising it as inferior work by inferior people is (i feel) unfair and incorrect.
