Mesa supports a Microsoft d3d12 video card driver to provide accelerated video in A Windows Subsystem for Linux 2 (WSL2). Currently this is default masked and enable only for amd64 and x86 profiles. $ grep -r d3d12 /var/db/repos/gentoo/profiles/* /var/db/repos/gentoo/profiles/arch/base/use.mask:video_cards_d3d12 /var/db/repos/gentoo/profiles/arch/amd64/use.mask:-video_cards_d3d12 /var/db/repos/gentoo/profiles/arch/x86/use.mask:-video_cards_d3d12 /var/db/repos/gentoo/profiles/desc/video_cards.desc:d3d12 - VIDEO_CARDS seeting to build driver for Microsoft WSL video cards WSL2 on a Windows arm64 system is also a valid target for video_cards_drd12 This mask can be overridden by adding "-video_cards_d3d12" to /etc/portage/profile/use.mask. media-libs/mesa is the only package that uses video_cards_d3d12, it emerges on successfully on arm64 when the mask is overridden.
