* kvm-arm64/lpi-xarray: : xarray-based representation of vgic LPIs : : KVM's linked-list of LPI state has proven to be a bottleneck in LPI : injection paths, due to lock serialization when acquiring / releasing a : reference on an IRQ. : : Start the tedious process of reworking KVM's LPI injection by replacing : the LPI linked-list with an xarray, leveraging this to allow RCU readers : to walk it outside of the spinlock. KVM: arm64: vgic: Don't acquire the lpi_list_lock in vgic_put_irq() KVM: arm64: vgic: Ensure the irq refcount is nonzero when taking a ref KVM: arm64: vgic: Rely on RCU protection in vgic_get_lpi() KVM: arm64: vgic: Free LPI vgic_irq structs in an RCU-safe manner KVM: arm64: vgic: Use atomics to count LPIs KVM: arm64: vgic: Get rid of the LPI linked-list KVM: arm64: vgic-its: Walk the LPI xarray in vgic_copy_lpi_list() KVM: arm64: vgic-v3: Iterate the xarray to find pending LPIs KVM: arm64: vgic: Use xarray to find LPI in vgic_get_lpi() KVM: arm64: vgic: Store LPIs in an xarray Signed-off-by: Oliver Upton <oliver.upton@linux.dev> |
