The Linux 6.15 kernel is set to remove support for IBM Cell Blade servers for those server platforms from around two decades ago that used the Cell Broadband Engine Architecture processors. IBM Cell Blades at the time powered a few supercomputers but these IBM QS20 / QS21 / QS22 platforms are no longer relevant and the IBM Linux kernel maintainers no longer even have these platforms available/running. With no apparent users remaining, it's time to say goodbye to the IBM Cell Blades from the mainline kernel...

Linux 6.14 is what's set to go on and power Ubuntu 25.04, Fedora 42, and other spring 2025 Linux distribution releases...

What a week. Last week Intel published a new AVX10 whitepaper where they dropped the optional 512-bit support of AVX10.2 and confirmed future P and E cores will have AVX10.2-512 support unconditionally. A very welcome change by Intel albeit late in rushing to get patches out to change that behavior ahead of the GCC 15 stable compiler release as well as working similar changes into the LLVM Clang compiler. As of today those GNU Compiler Collection patches have been merged to prepare for AVX10.2 always having 512-bit support available...

Coming out this week was an updated AVX10 whitepaper from Intel with the surprising decision that 512-bit floating point and integer support is no longer considered optional for AVX10.2. AVX10.2 now mandates 128 / 256 / 512-bit support and in turn also dropped the 256-bit embedded rounding support with the focus on 512-bit. The LLVM/Clang compiler had seen its AVX10 support designed around Intel's original AVX10 design assumptions and thus now is being modified to address these changes...
