[Qemu-devel] [PATCH V7 0/8] PSCI v0.2 support for KVM ARM/ARM64

[Pranavkumar Sawargaonkar <pranavkumar@linaro.org>]

This patchset adds the QEMU side changes for providing PSCI v0.2 to VM.

ChangeLog:

V7:
- Sync linux headers against kvm tree and "next" branch

V6:
- Add psci_version field in ARMCPU struct.
- Misc cleanups suggested on RFC V5 of this patch.
 ( http://www.spinics.net/lists/kvm-arm/msg09400.html)
- Dropping RFC prefix from patch.

V5:
- Updated "scripts/update-linux-headers.sh" to include linux/psci.h
- Synced linux headers using update-linux-headers.sh with linux-next tree
- Added per cpu field for kvm init features.
- Set psci-0.2 compatible string in generated dtb sucn that it works for 
  guest kernel not having psci 0.2 support.
- Added QEMU_KVM_CAP_ARM_PSCI_0_2 define in target-arm/kvm-consts.h

V4:
- Rebase this patch against v11 patchset for in-kernel PSCI v0.2 emulation
 (http://www.spinics.net/lists/kvm-arm/msg09182.html)
- Used PSCI 0.2 DT bindings for linux kernel.
  (http://www.spinics.net/lists/arm-kernel/msg326044.html).

V3:
 - Rebase this patchset against v8 patchset for in-kernel PSCI v0.2 emulation
   (http://www.spinics.net/lists/kvm-arm/msg08780.html)
 - Added common kvm_arm_vcpu_init() function for kvm arm and kvm arm64

V2:
 - Rebase this patchset against v6 patchset for in-kernel PSCI v0.2 emulation
   (http://www.spinics.net/lists/arm-kernel/msg319037.html)
 - Handle KVM_EXIT_SYSTEM_EVENT in kvm-all.c:kvm_cpu_exec()
 - Drop change in kvm_arm_get_host_cpu_features()
 - Improve comments and description of kvm_arch_reset_vcpu() implementation

V1:
 - Initial RFC patchset

Pranavkumar Sawargaonkar (8):
  update-linux-headers.sh: Add psci.h to linux header sync-up script
  linux-headers: Update KVM headers with kvm tree's next branch.
  kvm: Handle exit reason KVM_EXIT_SYSTEM_EVENT
  target-arm: Common kvm_arm_vcpu_init() for KVM ARM and KVM ARM64
  target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature when possible
  target-arm: Implement kvm_arch_reset_vcpu() for KVM ARM64
  target-arm: Introduce per-CPU field for PSCI version
  Use PSCI v0.2 compatible string when KVM or TCG provides it
