Another Look At The Performance Impact To IBM's POWER9 L1d Flushing Change

Phoronix - Fri, 12/04/2020 - 23:00
Last week I provided some benchmarks looking at the IBM POWER9 mitigation for the L1 data cache needing to be flushed upon entering the kernel and on user accesses due to a recently disclosed vulnerability. POWER9 allows speculatively operating on validated data in the L1 cache, but when it comes to incompletely validated data paired with other side channels it could lead to local users potentially obtaining improper access to data in the L1 data cache. When benchmarking the impact on a POWER9 4c/16t CPU the overall impact was fairly modest while since then I fired up some benchmarks as well on a large POWER9 server with 44 cores / 176 threads to see the performance impact of this default Linux kernel change.

When I saw Stack Overflow Chief Product Officer (CPO) Teresa Dietrich on the list of speakers at the All Things Open conference this year, I jumped at the chance to get an update.
