While the x32 psABI specifications are not fully finalized, this Yocto Project release supports current development specifications of x32 psABI. As of this release of the Yocto Project, x32 psABI support exists as follows:
You can create packages and images in x32 psABI format on x86_64 architecture targets.
You can use the x32 psABI support through the meta-x32
layer on top of the OE-core/Yocto layer.
The toolchain from the experimental/meta-x32 layer
is used for building x32 psABI program binaries.
You can successfully build many recipes with the x32 toolchain.
You can create and boot core-image-minimal and
core-image-sato images.
