Subject: [Buildroot] [PATCH] package/mesa3d: add intel-virtio host native context config
Date: Fri, 10 Jul 2026 08:32:25 -0500 [thread overview]
Message-ID: <20260710133225.484041-1-aford173@gmail.com> (raw)
Add BR2_PACKAGE_MESA3D_HOST_NATIVE_CONTEXT_DRIVER_INTEL in the same
pattern as amdgpu-virtio. When enabled, -Dintel-virtio-experimental=true
defines HAVE_INTEL_VIRTIO so the guest-side Intel native context
(i915 and xe context types) is compiled in. This is the guest half
of the Intel vDRM GPU passthrough path, usable by the crocus/iris
(OpenGL) and ANV (Vulkan) drivers.
Note that this is an experimental Mesa feature (the upstream meson
option is named intel-virtio-experimental) and is disabled by default.
