Merge branch kvm-arm64/vm-configuration into kvmarm/next
* kvm-arm64/vm-configuration: (29 commits)
: VM configuration enforcement, courtesy of Marc Zyngier
:
: Userspace has gained the ability to control the features visible
: through the ID registers, yet KVM didn't take this into account as the
: effective feature set when determing trap / emulation behavior. This
: series adds:
:
: - Mechanism for testing the presence of a particular CPU feature in the
: guest's ID registers
:
: - Infrastructure for computing the effective value of VNCR-backed
: registers, taking into account the RES0 / RES1 bits for a particular
: VM configuration
:
: - Implementation of 'fine-grained UNDEF' controls that shadow the FGT
: register definitions.
KVM: arm64: Don't initialize idreg debugfs w/ preemption disabled
KVM: arm64: Fail the idreg iterator if idregs aren't initialized
KVM: arm64: Make build-time check of RES0/RES1 bits optional
KVM: arm64: Add debugfs file for guest's ID registers
KVM: arm64: Snapshot all non-zero RES0/RES1 sysreg fields for later checking
KVM: arm64: Make FEAT_MOPS UNDEF if not advertised to the guest
KVM: arm64: Make AMU sysreg UNDEF if FEAT_AMU is not advertised to the guest
KVM: arm64: Make PIR{,E0}_EL1 UNDEF if S1PIE is not advertised to the guest
KVM: arm64: Make TLBI OS/Range UNDEF if not advertised to the guest
KVM: arm64: Streamline save/restore of HFG[RW]TR_EL2
KVM: arm64: Move existing feature disabling over to FGU infrastructure
KVM: arm64: Propagate and handle Fine-Grained UNDEF bits
KVM: arm64: Add Fine-Grained UNDEF tracking information
KVM: arm64: Rename __check_nv_sr_forward() to triage_sysreg_trap()
KVM: arm64: Use the xarray as the primary sysreg/sysinsn walker
KVM: arm64: Register AArch64 system register entries with the sysreg xarray
KVM: arm64: Always populate the trap configuration xarray
KVM: arm64: nv: Move system instructions to their own sys_reg_desc array
KVM: arm64: Drop the requirement for XARRAY_MULTI
KVM: arm64: nv: Turn encoding ranges into discrete XArray stores
