* kvm-arm64/pv-cpuid: : Paravirtualized implementation ID, courtesy of Shameer Kolothum : : Big-little has historically been a pain in the ass to virtualize. The : implementation ID (MIDR, REVIDR, AIDR) of a vCPU can change at the whim : of vCPU scheduling. This can be particularly annoying when the guest : needs to know the underlying implementation to mitigate errata. : : "Hyperscalers" face a similar scheduling problem, where VMs may freely : migrate between hosts in a pool of heterogenous hardware. And yes, our : server-class friends are equally riddled with errata too. : : In absence of an architected solution to this wart on the ecosystem, : introduce support for paravirtualizing the implementation exposed : to a VM, allowing the VMM to describe the pool of implementations that a : VM may be exposed to due to scheduling/migration. : : Userspace is expected to intercept and handle these hypercalls using the : SMCCC filter UAPI, should it choose to do so. smccc: kvm_guest: Fix kernel builds for 32 bit arm KVM: selftests: Add test for KVM_REG_ARM_VENDOR_HYP_BMAP_2 smccc/kvm_guest: Enable errata based on implementation CPUs arm64: Make _midr_in_range_list() an exported function KVM: arm64: Introduce KVM_REG_ARM_VENDOR_HYP_BMAP_2 KVM: arm64: Specify hypercall ABI for retrieving target implementations arm64: Modify _midr_range() functions to read MIDR/REVIDR internally Signed-off-by: Oliver Upton <oliver.upton@linux.dev> |
