Subject: [PATCH v3 00/19] KVM: arm64: Transition to a per-ITS translation cache
Date: Mon, 22 Apr 2024 20:01:39 +0000 [thread overview]
Message-ID: <20240422200158.2606761-1-oliver.upton@linux.dev> (raw)
v2: https://lore.kernel.org/kvmarm/20240419223842.951452-1-oliver.upton@linux.dev/
v2 -> v3:
- Add lockdep assertion to kvm_vfio_create() (Sean)
- Address intermediate compilation issue in vgic_its_invalidate_cache()
(Marc)
- Use a more compact cache index based on the DID/EID range of the ITS
(Marc)
- Comment improvements (Marc)
- Avoid explicit acquisition of the translation cache's xa_lock()
(Marc)
- Eliminate the need to disable IRQs to acquire the translation cache's
xa_lock()
- Collapse internal helper into vgic_its_check_cache()
Oliver Upton (19):
KVM: Treat the device list as an rculist
KVM: arm64: vgic-its: Walk LPI xarray in its_sync_lpi_pending_table()
KVM: arm64: vgic-its: Walk LPI xarray in vgic_its_invall()
KVM: arm64: vgic-its: Walk LPI xarray in vgic_its_cmd_handle_movall()
KVM: arm64: vgic-debug: Use an xarray mark for debug iterator
KVM: arm64: vgic-its: Get rid of vgic_copy_lpi_list()
KVM: arm64: vgic-its: Scope translation cache invalidations to an ITS
KVM: arm64: vgic-its: Maintain a translation cache per ITS
KVM: arm64: vgic-its: Spin off helper for finding ITS by doorbell addr
KVM: arm64: vgic-its: Use the per-ITS translation cache for injection
KVM: arm64: vgic-its: Rip out the global translation cache
KVM: arm64: vgic-its: Get rid of the lpi_list_lock
KVM: selftests: Align with kernel's GIC definitions
KVM: selftests: Standardise layout of GIC frames
KVM: selftests: Add quadword MMIO accessors
KVM: selftests: Add a minimal library for interacting with an ITS
KVM: selftests: Add helper for enabling LPIs on a redistributor
KVM: selftests: Use MPIDR_HWID_BITMASK from cputype.h
KVM: selftests: Add stress test for LPI injection
