MAD24 307 Arm64 Linux kernel Architectural Updates

The Arm64 Linux Kernel is constantly evolving to align with the disruptive Arm architecture enablement story, spanning across 3 spheres : performance, compute and security. At Arm, we drive this kernel enablement story to facilitate our architecture adoption. The shared ownership helps us to sustain the value of upstream contribution in the bigger Linux Kernel community. This talk walks us through the Arm architectural upstream story comprising deltas from 2021/2022 extensions (v8.8,v8.9 arch), CCA kernel highlights, advanced Arm arch features for 2023+ extensions, mainly from kernel perspective, touching on Distros wherever applicable. The session also provides a forward looking deliberation for investigation areas to be explored in the Kernel space.
