    Bonus. At some point during the day we turned off two kernel security mitigations on the rig: spec_rstack_overflow=off retbleed=off The prefill thread was doing millions of syscalls per second, and on Zen 2 every single one pays the SRSO "safe RET" tax (CVE-2023-20569, the Inception attack). With mitigations off, sched_yield went from 549 ns to 162 ns, minus 70%. End to end it bought a whole +2% prefill. Yes. We disabled a CVE mitigation for two percent. Do not repeat this on any machine that runs code you do not trust, this rig is a local box behind a router and this risk is mine only. The things you do for tokens per second ❤️

    Post summary

    The user disabled kernel mitigations for CVE‑2023‑20569 to gain a 70% performance improvement on a local box; the post provides a workaround but no active exploitation or detailed technical vulnerability data.

    @AIPulseNewsX Kernels have no further optimization possible at the moment. Currently I am at the stage of disabling mitigation of the SRSO / Inception vulnerability (CVE-2023-20569) - a speculative attack on the return address predictor in AMD Zen 1 to 4. 🤡📷

    Post summary

    The author notes they are disabling mitigation for CVE-2023‑20569, a speculative return-address-predictor attack on AMD Zen 1‑4, highlighting a workaround rather than active exploitation.
