Mesa 22.3-rc2 Released With A Few AMD RDNA3 Fixes, V3DV Fixes For Raspberry Pi

Following last week's release of Mesa 22.3-rc1 that also marked the feature freeze for this quarter's release cycle, Mesa 22.3-rc2 is out today with an initial batch of bug fixes.

There are a few AMD RDNA3/GFX11 fixes that came about in the past week for fixing the compute scratch buffer handling in the GFX11 code path with RadeonSI Gallium3D and then there are two fixes for the RADV Vulkan driver to correct the proper driver behavior for the GFX11 graphics IP. It's likely more AMD RDNA3 fixes will come for RadeonSI and RADV over the weeks ahead and in the lead up to the 13 December launch of the Radeon RX 7900 series graphics cards. Stay tuned for my RX 7900 XT / RX 7900 XTX Linux reviews next month for finding out about the Linux support state.

Also notable with this week's release candidate are a handful of fixes to the Broadcom V3DV Vulkan driver, most notably used by the Raspberry Pi 4 and newer.

Other fixes in Mesa 22.3-rc2 include a few Intel ANV fixes, fixing some build problems on Android, a couple Panfrost Gallium3D fixes, and other random fixes throughout this collection of open-source user-space graphics driver code.

Mesa 22.3 stable will be out in late November or early December. This is an exciting update with the introduction of Rusticl, the new Mesa single-file shader cache type, many new Vulkan extensions for the Intel and RADV drivers, continued LLVMpipe and Lavapipe enhancements, Zink continuing to become more performant, initial RDNA3/GFX11 support,continued Intel Arc Graphics improvements, and much more.
