Mesa 25.2.0 is formally out now as the most recent new function launch of open supply graphics drivers for Linux. There’s numerous adjustments with this one from huge new options, plenty of completely different drivers seeing enhancements and the same old assortment of bug fixes.
From the mailing record launch announcement developer Eric Engestrom stated:
This launch contains some main house-cleaning of the window system code to take away help for deprecated performance:
– DRI2 help has been eliminated completely. X11 window system help is now solely out there by DRI3 or software program paths. This could in a roundabout way influence customers as DRI2 has been deprecated for a while.
– Help for the insecure legacy GEM names has additionally been eliminated and buffer sharing is now solely supported utilizing dma-buf file descriptors. This also needs to not have an effect on customers as dma-buf has been the popular path for a couple of decade.
– Help for thread-unsafe libX11 has been eliminated. Mesa now requires libX11 >= 1.8 (April 2022) which calls XInitThreads() on load and ensures libX11 is all the time thread-safe. libX11 should not be constructed with –disable-thread-safety-constructor since that disables the XInitThreads() name.
– Help for EGL_WL_bind_wayland_display has been deprecated and is now hidden behind the -Dlegacy-wayland=bind-wayland-display construct flag. To ensure that XWayland to work correctly with out EGL_WL_bind_wayland_display, distros might want to improve to Xwayland >= 24.1 (Could 2024).One other vital issues is that, as introduced throughout `meson setup` since 25.0.2, the Clover OpenCL implementation has been deleted. RustiCL is now the one OpenCL implementation out there, offering help for extra OpenCL variations and options and to extra {hardware} than Clover ever did. It’s not (but) excellent although, so please report any difficulty you discover whereas utilizing it.
NVK has added a dependency on the rustc-hash crate, which has improved shader compile occasions by an estimated 12%. We imagine rustc-hash is already extensively packaged, so the hope is that this would possibly not pose a lot of a burden to packagers.
Talking of NVK, it now helps NVIDIA’s Blackwell and Kepler architectures. The previous Nouveau GL driver has not been up to date for Blackwell and there are not any plans to take action. As an alternative, Nouveau customers will solely get OpenGL through Zink+NVK on any GPUs after Ada. (Kepler customers will nonetheless get the previous Nouveau GL driver as it’s nonetheless the default pre-Turing.)
HoneyKrisp, the Apple Vulkan driver, has seen vital efficiency enhancements.
