Linux 6.12 Finishing The Transition For Moving Intel CPUs Past The "Family 6" Era

Phoronix - Sat, 09/14/2024 - 04:22
As written about early in the year, future Intel CPUs will be moving past the "Family 6" identification used since the mid-1990s with the P6 micro-architecture. Since then Intel has continued releasing new CPUs under "Family 6" with different model IDs while AMD has been more open to changing its Family ID every Zen generation or two. With Intel using Family 6 for so long it led to a lot of Linux kernel code just relying on Model ID comparisons for determining between Intel CPU generations and the like. Thus a lot of Intel CPU model handling reworks are needed for preparing future Intel CPU generations that will no longer be in Family 6. With Linux 6.12 it looks like that work will be wrapping up...

AMD Engineer Proposes "Attack Vector Controls" To Rethink CPU Security Mitigation Handling

Phoronix - Fri, 09/13/2024 - 19:16
David Kaplan who is a Senior Fellow at AMD focused on security technologies has published an initial set of Linux kernel patches for "Attack Vector Controls" in rethinking the CPU security mitigation handling. The proposed Attack Vector Controls makes it easier to manage desired security mitigations to have enabled/disabled based upon intent of the system rather than having to be knowledgeable about individual CPU security vulnerabilities and the various tuning knobs...
