What were you trying to do that didn't work?

When booting a Eviden BullSequana SH160, Dell S5516 or Hitachi DS9160 server with more than 4 sockets, the kernel rejects the TSR adjust architecural MSR values, using 0 instead.

After this occurs, the system falls back to HPET timekeeping, which severely limits performance.

Please provide the package NVR for which bug is seen:

kernel-5.14.0-70.13.1.el9_0.x86_64

How reproducible:

100% (every boot)

Steps to reproduce

Activate TSC synchronisation in the aforementioned servers
Boot with >4 sockets
Observe the kernel resetting the TSC adjust architectural MSRs to 0

Expected results

The kernel trusts and accepts the values programmed the in the TSC adjust architectural MSRs, as setup by the BIOS.

Actual results

The kernel rewrites these MSRs with 0.

Additional notes

I have prepared and published a kernel patch to address the issue upstream:
