Re: [win-pv-devel] v9.0.0 released

[Steffan Cline <steffan@xxxxxxxxx>]

Paul,

I upgraded Xen to 4.12. One of the lines from your config is 

viridian = [ 'base', 'freq', 'time_ref_count', 'reference_tsc', 
'hcall_remote_tlb_flush', 'apic_assist', 'crash_ctl', 'stimer', 'hcall_ipi' ]

but with my distro/Xen the most it would utilize is

viridian = [ 'base', 'freq', 'time_ref_count', 'reference_tsc', 
'hcall_remote_tlb_flush', 'apic_assist', 'crash_ctl' ]

On this VM which is Win Server 2019, I have all of the latest 9.0.0 drivers 
installed. I tried them in Win 2012R2 but had to remove the USB drivers since 
it wouldn't even detect mouse clicks.

Anyway, after the updates you can see the write speed dropped a bit but the 4K 
read went up a bit. Do these numbers still look normal?

I've attached the speeds for xen 4.8 and 4.12

 
Thank you,
Steffan Cline

    I don't think there's anything particular that you're missing but that 4k 
read number looks abnormally low compared to the other numbers, which I guess 
is due to the 8.3ms acc time. What version of Xen are you running on BTW?
