Subject: [PATCH v4 00/19] KVM: arm64: Debug cleanups
Date: Fri, 4 Apr 2025 09:52:33 -0700 [thread overview]
Message-ID: <20250404165233.3205127-11-oliver.upton@linux.dev> (raw)
In-Reply-To: <20250404165233.3205127-1-oliver.upton@linux.dev>
Hopefully the last round.
v3 -> v4:
- Collect Tested-by from James (thanks!)
- Delete stray if condition (Marc)
- Write mdcr_el2 from kvm_arm_setup_mdcr_el2() on VHE
- Purge DBGxVR/DBGxCR accessors since it isn't nice to look at
Oliver Upton (19):
KVM: arm64: Drop MDSCR_EL1_DEBUG_MASK
KVM: arm64: Get rid of __kvm_get_mdcr_el2() and related warts
KVM: arm64: Track presence of SPE/TRBE in kvm_host_data instead of
vCPU
KVM: arm64: Move host SME/SVE tracking flags to host data
KVM: arm64: Write MDCR_EL2 directly from kvm_arm_setup_mdcr_el2()
KVM: arm64: Evaluate debug owner at vcpu_load()
KVM: arm64: Clean up KVM_SET_GUEST_DEBUG handler
KVM: arm64: Select debug state to save/restore based on debug owner
KVM: arm64: Remove debug tracepoints
KVM: arm64: Remove vestiges of debug_ptr
KVM: arm64: Use debug_owner to track if debug regs need save/restore
KVM: arm64: Reload vCPU for accesses to OSLAR_EL1
KVM: arm64: Compute MDCR_EL2 at vcpu_load()
KVM: arm64: Don't hijack guest context MDSCR_EL1
KVM: arm64: Manage software step state at load/put
KVM: arm64: nv: Honor MDCR_EL2.TDE routing for debug exceptions
KVM: arm64: Avoid reading ID_AA64DFR0_EL1 for debug save/restore
KVM: arm64: Fold DBGxVR/DBGxCR accessors into common set
KVM: arm64: Promote guest ownership for DBGxVR/DBGxCR reads
