The forwarding of the Linux-measured TSC frequency is an offer to the
inmates, not a must-use. You ca
I also noticed this.
I am working on a Broadwell machine with 2.2Ghz of core frequency.
Jailhouse get set the cpu_khz in comm region with the frequency probed by
Linux during boot.
I got somthing like ~2.1997Ghz in that field.
The difference is so small that I don't have a good way to evaluate
I guess I should clarify (for my future sake, at least) that the Jailhouse
driver automatically passes this Linux-derived frequency into each cell's
config, while I'm planning on measuring frequency information from the MSRs
directly within an inmate.

Hello,
I notice that on my machine (Coffee Lake architecture, Intel 8th
Generation), apparently Linux detects a TSC frequency of 3,696,003,000 Hz.
However, the Intel SDM Vol. 4 Table 2-20, under bits 8-15 of the
PLATFORM_INFO_MSR (0xCE), says that the invariant TSC runs at the Maximum
Non
