Status update, April 2024

Hi!

The X.Org Foundation results are in, and I’m now officially part of the Board of Directors. I hope I can be of use to the community on more organizational issues! Speaking of which, I’ve spent quite a bit of time dealing with Code of Conduct matters lately. Of course I can’t disclose details for privacy, but hopefully our actions can gradually improve the contribution experience for FreeDesktop.Org projects.

New extensions have been merged in wayland-protocols. linux-drm-syncobj-v1 enables explicit synchronization which is a better architecture than what we have today (implicit synchronization) and will improve NVIDIA support. alpha-modifier-v1 allows Wayland clients to set an alpha channel multiplier on its surfaces, it can be used to implement effects such as fade-in or fade-out without redrawing, and can even be offloaded to KMS. The tablet-v2 protocol we’ve used for many years has been stabilized.

In other Wayland news, a new API has been added to dynamically resize libwayland’s internal buffer. By default, the server-side buffer size is still 4 KiB but the client-side buffer will grow as needed. This should help with bursts (e.g. long format lists) and high poll rate mice. I’ve added a new wayland-scanner mode to generate headers with only enums to help libraries such as wlroots which use these in their public API. And I’ve sent an announcement for the next Wayland release, it should happen at the end of May if all goes well.

With the help of Sebastian Wick, libdisplay-info has gained support for more bits, in particular DisplayID type II, III and VII timings, as well as CTA Video Format Preference blocks, Room Configuration blocks and Speaker Location blocks. I’ve worked on libicc to finish up the parser, next I’d like to add the math required to apply an ICC profile. gamja now has basic support for file uploads (only when pasting a file for now) and hides no-op nickname changes (e.g. from “emersion” to “emersion_” and back).

See you next month!
