mesa: update to version 26.2.2

2026-09-18T15:16:45Z

26.2.0 was a development release which upstream advised against using; 26.2.1 is the first stable point release on the 26.2 branch and 26.2.2 adds further bug fixes on top of it, among them the armhf build fix and one potential security issue. Drop patch 400, whose fix is now present upstream, and refresh the remaining patches. Add a new patch adapting the gallivm ORCJIT object linking layer creator to the signature change in LLVM 23, which targets without MCJIT support such as riscv64 need. Signed-off-by: Daniel Golle

mesa: update to 26.0.6, add virtio + teflon (rocket / etnaviv)

2026-05-17T11:46:41Z

Bump mesa from 25.2.4 to latest stable point release in the 26.0.x series. Drop 001-gallivm-support-LLVM-21.patch which has been merged upstream. Refresh the remaining downstream patches (100-meson-allow-using-LLVM-as-embedded-project, 200-panfrost-Enable-cross-compilation-of-precompilers-on) for the new upstream context. Add +libdisplay-info to the DEPENDS of every libvulkan-* package (broadcom, imagination, intel, intel-hasvk, lvp, panfrost, radeon, virtio): Mesa 26.0 unconditionally pulls libdisplay-info into the WSI Vulkan path on Linux (gated only by host_machine.system() == 'windows'), so every ICD now NEEDED-links libdisplay-info.so.3 and OpenWrt's shlibs check rejects packages without the explicit dependency. libvulkan-nouveau is @BROKEN (needs Rust) so it does not get touched. The 'imagination-experimental' vulkan-drivers value got renamed to plain 'imagination' in Mesa 26; update the VULKAN_DRIVERS entry accordingly. Add 'imagination' to the host build's -Dtools= list so the PowerVR pco_clc precompiler is built and installed into $(STAGING_DIR_HOSTPKG)/bin/ during the host-build stage. The target vulkan variant uses -Dprecomp-compiler=system and looks the binary up there via find_program('pco_clc', native:true); without this, the target configure stage fails with "Program 'pco_clc' not found or not executable" as soon as the imagination vulkan driver enters the gallium tree. New packages: * libvulkan-virtio: the venus virtio-gpu Vulkan ICD, useful for VM/container guests forwarding Vulkan to a host GPU. Mirrors the libvulkan-lvp install pattern. Wired via VULKAN_DRIVERS+=virtio. * libteflon-rocket and libteflon-etnaviv: two flavours of mesa's "teflon" TensorFlow Lite delegate. teflon links one or more NPU back-ends from gallium into a libteflon.so that TFLite loads as an external delegate. The two variants here cover the NPU silicon found on OpenWrt-supported hardware: - rocket: Rockchip RKNPU on RK3566 / RK3568 / RK3588(s) (rockchip/armv8 target). - etnaviv: VeriSilicon VIP9000-class NPU on NXP i.MX 8M Plus and i.MX 95 (imx/cortexa53 target). The Arm Ethos-U back-end is omitted; it targets Cortex-M55 MCUs which OpenWrt does not run on. Each variant is its own VARIANT= mesa build with -Dgallium-drivers= -Dteflon=true; both produce /usr/lib/libteflon.so so the two packages declare each other as CONFLICTS (typical OpenWrt mesa-variant pattern). A small downstream patch (300-teflon-conditional-npu-drivers.patch) adjusts src/gallium/targets/teflon/meson.build so that the driver_etnaviv / driver_rocket / driver_ethosu link_with entries are conditional on with_gallium_ instead of unconditional. Without it, building libteflon with only one back-end fails because the other driver_X meson variables are undefined when the corresponding gallium-driver is not selected. Add 400-gallivm-lp-bld-misc-auto-iter-llvm22.patch to fix the 32-bit ARM build with the new LLVM 22. lp_bld_misc.cpp's DETECT_ARCH_ARM branch (only reached on ARM-32) iterates the feature StringMap with an explicit 'llvm::StringMapIterator' type, which LLVM 22 renamed to 'llvm::StringMapIterBase'. Use 'auto' for the iterator declaration so the code works regardless of the LLVM major. Other targets (aarch64, x86, x86_64, mips, ppc, riscv) are unaffected because the failing loop is gated on DETECT_ARCH_ARM. Disable -Dllvm and -Ddraw-use-llvm in the per-variant MESON_ARGS for the gallium drivers where the aux 'draw' module is *dead code*: softpipe, broadcom (vc4/v3d), lima, etnaviv, teflon-rocket and teflon-etnaviv. Confirmed by inspecting 26.0.6 source: each of v3d, vc4, lima, etnaviv, panfrost (and the NPU-only rocket/etnaviv teflon paths) registers its own pipe_context->draw_vbo and never calls any draw_* aux-module function (0 draw_create, 0 draw_set_so_targets, 0 draw_set_indirect_buffer, 0 draw_*_geometry, 0 src includes of draw/*.h apart from one unused header in pan_screen.c). Transform feedback, geometry shaders and indirect draws are handled either in hardware or via the driver's own compute path, never through the aux-draw module. softpipe and llvmpipe are the only consumers of the aux-draw module; mesa.meson.build also forces draw-use-llvm=true for llvmpipe/lavapipe/i915/r300-x86. Net effect on libgallium-26.0.6.so, measured on arm_cortex-a7+neon-vfpv4 (mediatek/mt7623): variant libgallium before libgallium after .apk after ---------------------------------------------------------------- softpipe 57.7 MB 16 MB 2.9 MB broadcom 57.7 MB 16 MB 3.2 MB lima 57.7 MB 16 MB 3.0 MB etnaviv 57.7 MB 16 MB 2.9 MB teflon-rocket ~57 MB ~16 MB varies teflon-etnaviv ~57 MB ~16 MB varies llvmpipe 57.9 MB 55-56 MB 15 MB (unchanged - keeps LLVM) LLVM-related strings in the LLVM-disabled variants drop from 208/220 to 5 (just stub strings that survive in the no-LLVM draw path). The 41 MB removed from each was statically-linked LLVM JIT that no code path in those drivers ever executed. Relax the build-time dependency on llvm-mesa: a user who selects only LLVM-free Mesa variants (softpipe/broadcom/lima/ etnaviv/teflon-*) no longer needs to build the entire llvm-mesa package (which can take 30+ minutes from source). MESA_USE_LLVM remains a user-visible toggle (defaults y for backward compat). With CONFIG_MESA_USE_LLVM=n: * HOST_BUILD_DEPENDS drops the unconditional 'llvm' (now MESA_USE_LLVM:llvm), matching PKG_BUILD_DEPENDS. * MESON_HOST_ARGS skips -Dllvm/-Dmesa-clc/-Dprecomp-compiler/ -Dstatic-libclc/-Dinstall-mesa-clc/-Dinstall-precomp-compiler and trims -Dtools to just 'nir'. * Host/Configure factors its LLVM-subproject linkage into a Host/Configure/LLVMMesa hook, mirroring the existing Build/Configure/LLVMMesa pattern. Tested locally on arm_cortex-a7+neon-vfpv4 (mediatek/mt7623): * MESA_USE_LLVM=y, libmesa-softpipe + libmesa-llvmpipe: builds llvm-mesa, then mesa softpipe (38s, no-LLVM libgallium) and llvmpipe (42s, LLVM-linked libgallium 56 MB). All correct. * MESA_USE_LLVM=n, libmesa-softpipe only: 0 llvm/compile invocations, 0 mesa/host-compile invocations, total mesa build time 38s. libmesa-softpipe .apk identical (2.9 MB) to the MESA_USE_LLVM=y case.

mesa: update to version 25.2.4

2025-10-19T13:53:15Z

Mesa 25.2 brings a bunch of new features, especially the Panfrost Vulkan driver saw many improvements. See https://docs.mesa3d.org/relnotes.html for details about what has happened since Mesa 25.1.6. Note that OSMesa as well as the old OpenCL 1.1 support has been dropped. The new Rusticl OpenCL implementation cannot be supported yet as OpenWrt's meson integration still lacks support for Rust at this point. Signed-off-by: Daniel Golle

mesa: update to 25.1.5

2025-07-17T22:53:34Z

Support for off-screen rendering ("libOSMesa") has been dropped upstream. In order to still be able to cross-compile the panfrost driver also on non-Linux buildhosts, or Linux hosts without libdrm, a patch has been applied.

mesa: fix dependencies and always prefer LLVM subproject

2024-12-07T21:58:31Z

Make sure build dependency to mesa/host is set for x86 and x86/64 builds, add missing dependency on Python ply and make sure to always prefer LLVM subproject to avoid picking up LLVM from the build host (which may not match SPIR-V converter tool version). Signed-off-by: Daniel Golle

mesa: update to 24.3.0, improve build

2024-12-05T01:15:41Z

Apart from switching to a newer upstream version, also improve the build: * introduce build-variants for each kind of hardware * use LLVM * build more Gallium drivers * build Vulkan drivers * build Clover OpenCL library Signed-off-by: Daniel Golle
