Intel Compute Runtime - Upgrade with HW cut-off

This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

Intel Compute Runtime parts are currently stuck at a legacy branch that isn't undergoing an active development. Newer branches did significantly cut hardware support (for GPU Generations prior to the 12th), and the aim of this change is to do the leap of faith.

Detailed Description

Intel Compute Runtime, consisting of intel-compute-runtime, intel-igc, oneapi-level-zero, removed support for GPU Generations prior to the 12th Gen GPUs. This effectively means that any hardware released before 2022 is no longer supported for OpenCL and oneAPI workloads. The cut-off occurred first in compute-runtime with branch 24.39, and followed in rest of the components. The affected architectures are listed at LEGACY_PLATFORMS:

• Broadwell
• Skylake
• Kaby Lake
• Coffee Lake
• Apollo Lake
• Gemini Lake
• Ice Lake
• Elkhart Lake

Fedora packages thus stayed on the older branches that support older hardware generations up to Broadwell (released around 2015). These snapshots do miss support for newer Hardware generations, most notably Intel Battlemage GPUs, and upcoming graphics based on Xe3, and lack fixes and improvements for integrated Xe2 architecture products.

Apart from HW Support plane, it'll, over time, become problematic to keep the pieces working, as new kernels, headers, and compilers do break the suite on occasion, and older branches aren't getting fixes in these areas.

This change is to propose a rebase of the entire suite to the latest upstream branches, undergoing an active development and adding support for new products.
