Ubuntu to Disable Intel Graphics Security Mitigations for Performance Boost

Intel graphics security mitigations have been silently impacting performance, with disabling them potentially yielding a 20% boost for OpenCL and Level Zero GPU compute. Canonical, in collaboration with Intel, plans to disable these mitigations in Ubuntu packages to recapture this lost performance. This is enabled via the "NEO_DISABLE_MITIGATIONS" build option, already used in Intel's GitHub binaries. While a security risk exists, both Intel and Canonical security teams have approved this change, slated for Ubuntu 25.10. The mitigation primarily affects the Intel Compute Runtime and doesn't impact kernel-level security.
