This patchset updates KVMTOOL to use some of the features
supported by Linux-3.16 KVM ARM/ARM64, such as:
1. Target CPU == Host using KVM_ARM_PREFERRED_TARGET vm ioctl
2. Target CPU type Potenza for using KVMTOOL on X-Gene
3. PSCI v0.2 support for Aarch32 and Aarch64 guest
4. System event exit reason
Changes since v4:
- Avoid using magic '0' target for kvm arm generic target
- Added comment for why we need Potenza target in KVMTOOL
Changes since v3:
- Add generic targets for aarch32 and aarch64 which are used
by KVMTOOL when target type returned by KVM_ARM_PREFERRED_TARGET
vm ioctl is not known to KVMTOOL
- Print more info when handling system reset event
Changes since v2:
- Use target type returned by KVM_ARM_PREFERRED_TARGET vm ioctl
for VCPU init such that we don't need to update KVMTOOL for
every new host hardware
- Simplify DTB generation for PSCI node
Changes since v1:
- Drop the patch to fix compile error for aarch64
- Fallback to old method of trying all target types if
KVM_ARM_PREFERRED_TARGET vm ioctl fails
- Print more info when handling KVM_EXIT_SYSTEM_EVENT
Anup Patel (4):
kvmtool: ARM: Use KVM_ARM_PREFERRED_TARGET vm ioctl to determine
target cpu
kvmtool: ARM64: Add target type potenza for aarch64
kvmtool: Handle exit reason KVM_EXIT_SYSTEM_EVENT
kvmtool: ARM/ARM64: Provide PSCI-0.2 to guest when KVM supports it
