[PATCH kvmtool v6 0/3] aarch64: Add stolen time support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



These patches add support for stolen time functionality.

Patch #1 moves the vCPU structure initialisation before the target->init()
call to allow early access to the kvm structure from the vCPU
during target->init().

Patch #2 modifies the memory layout in arm-common/kvm-arch.h and adds a
new MMIO device PVTIME after the RTC region. A new flag is added in
kvm-config.h that will be used to control [enable/disable] the pvtime
functionality. Stolen time is enabled by default when the host
supports KVM_CAP_STEAL_TIME.

Patch #3 adds a new command line argument to disable the stolen time
functionality(by default is enabled).

Changelog since v5:
 - propagate the error code from the kvm_cpu__setup_pvtime() when the
   host supports KVM_CAP_STEAL_TIME but if fails to configure it for
   stolen time functionality.
