[RFC 0/4] kvm: arm64: emulate ID registers

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

 



In AArch64, guest will read the same values of the ID regsiters with
host.  Both of them read the values from arm64_ftr_regs.  This patch
series add support to emulate and configure ID registers so that we can
control the value of ID registers that guest read.

Peng Liang (4):
  arm64: add a helper function to traverse arm64_ftr_regs
  kvm: arm64: emulate the ID registers
  kvm: arm64: make ID registers configurable
  kvm: arm64: add KVM_CAP_ARM_CPU_FEATURE extension
