x86/hvm: reset TSC to 0 after domain resume from S3
|
|
|
|
Host S3 implicitly resets the host TSC to 0, but the tsc offset for hvm
|
|
domains is not recalculated when they resume, causing it to go into
|
|
negative values. In Linux guest using tsc clocksource, this results in
|
|
a hang after wrap back to positive values since the tsc clocksource
|
|
implementation expects it reset.
