Per Hyper-V specification (and as required by Hyper-V-aware guests),
SynIC provides 4 per-vCPU timers. Each timer is programmed via a pair
of MSRs, and signals expiration by delivering a special format message
to the configured SynIC message slot and triggering the corresponding
synthetic interrupt.
Could you post a link for this specification?

and there is a pdf variant(my own docx -> pdf conversion):

Btw, is there performance data for such feature?

not yet.
This is a requirement for any Hyper-V device emulation
to be activated by Windows. We are going to have
basic infrastructure merged and run performance tests
with all that stuff done.
