But now with upstream Intel Compute Runtime dropping support for Ice Lake and older leaves the Fedora support in a pickle. Currently they are focusing on the "legacy" branch with older hardware support but for Fedora 42 are looking at upgrading the support to focus on newer Intel graphics hardware support while leaving that older hardware support behind...
