The +highlight this month is the HDR hackfest, I've written a [dedicated blog +post][HDR hackfest] about it. After the publication of that blog post, I've +sent out an [RFC to dri-devel]. + +We've made some good progress on wlroots' Vulkan renderer. Manuel Stoeckl has +added support for an [intermediate buffer for blending], which is required for +non-8-bit output formats and for color management features. The renderer now +has an optional extra rendering pass to run a shader after blending. This is +currently used to encode color values to sRGB, and will be used in the future +to apply ICC profiles and to perform color space conversions. I've added +support for the [NV12 DMA-BUF format], support for more YCbCr formats is in a +merge request. + +The new [cursor-shape-v1 protocol] has been merged in wayland-protocols thanks +to KDE and winit folks. Traditionally Wayland clients needed to load XCursor +themes and submit these as `wl_shm` buffers to the compositor. However there +are a few downsides: there is no mechanism to configure the theme that gets +loaded, the theme cannot be changed on-the-fly, there is no way to configure +separate themes per seat, and loading cursors slows down client startup. The +cursor-shape-v1 protocol allows clients to set a cursor image by its name +instead of using `wl_shm` buffers. + +I've worked on adding a new mode to wayland-scanner to [generate enums only]. +This is useful for libraries like wlroots which use C enums generated from +protocol XML in their public headers. We plan to ship these headers as part of +a wayland-protocols installation. + +To wrap up this status update, let's mention a few updates for miscellaneous +projects. A handful of new formats have been added to [pixfmtdb]. [gqlclient] +now handles GraphQL interfaces correctly and generates methods to unwrap the +underlying type. This is now used in [hut] to show ticket comments, among other +things. [go-imap] now supports SEARCHRES, LITERAL+, and features a simplified +API for STATUS commands. + +See you next month! + +[HDR hackfest]: /blog/2023/hdr-hackfest-wrap-up/ +[RFC to dri-devel]: https://lore.kernel.org/dri-devel/QMers3awXvNCQlyhWdTtsPwkp5ie9bze_hD5nAccFW7a_RXlWjYB7MoUW_8CKLT2bSQwIXVi5H6VULYIxCdgvryZoAoJnC5lZgyK1QWn488=@emersion.fr/T/#u +[intermediate buffer for blending]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3869 +[NV12 DMA-BUF format]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4092 +[cursor-shape-v1 protocol]: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/194 +[generate enums only]: https://gitlab.freedesktop.org/wayland/wayland/-/merge_requests/312 +[pixfmtdb]: https://pixfmtdb.emersion.fr/ +[gqlclient]: https://git.sr.ht/~emersion/gqlclient +[hut]: https://sr.ht/~emersion/hut/ +[go-imap]: https://github.com/emersion/go-imap -- 2.45.2
