This patch set looks functionally good.
Some of the test steps I ran through are as follows:
Initialy attempt to query frequency from guest, it failed because
queries were disabled.
vmpower> set_query ubuntu3 disable
vmpower(guest)> query_cpu_freq all
GUEST_CLI: Error receiving message.
Error during frequency list reception
Then I enabled queries for the VM:
vmpower> set_query ubuntu3 enable
I was then able to query the freq list for all the cores in the VM:
vmpower(guest)> query_cpu_freq all
Frequency of [0] vcore is 2300000.
*Frequency of [1] vcore is 2300000.*
Frequency of [2] vcore is 2300000.
Frequency of [3] vcore is 2300000.
Frequency of [4] vcore is 2300000.
Frequency of [5] vcore is 2300000.
Frequency of [6] vcore is 2300000.
Frequency of [7] vcore is 2300000.
When a freq was changed in a core:
vmpower(guest)> set_cpu_freq 1 down
ACK received for message sent to host.
The frequency of core 1 had changed in the query, as expected:
vmpower(guest)> query_cpu_freq all
Frequency of [0] vcore is 2300000.
*Frequency of [1] vcore is 2200000.*
Frequency of [2] vcore is 2300000.
Frequency of [3] vcore is 2300000.
Frequency of [4] vcore is 2300000.
Frequency of [5] vcore is 2300000.
Frequency of [6] vcore is 2300000.
Frequency of [7] vcore is 2300000.
I've added a Tested-by tag to the v2 patchset.
Rgds,
Dave.
