Both flat table and 2 level tables are implemented.The ITS commands for adding/deleting ITS table entries,trigerring LPI interrupts are implemented.Translated LPI interrupt ids are processed by redistributor to determine priority and set pending state appropriately before forwarding the same to cpu interface. The ITS feature support has been added to virt platform,wherein the emulated functionality co-exists with kvm kernel functionality. Changes in v9: - removed sbsa-ref patch due to inconclusive ongoing discussion regarding ITS placement and version in sbsa-ref platform.This will be taken up as a separate functionality later - updated its enable code as per latest virt 6.2 - updated its code to replace usage of MEMTX_ with bool - All kvm_unit_tests PASS - Verified Linux Boot functionality Shashi Mallela (9): hw/intc: GICv3 ITS initial framework hw/intc: GICv3 ITS register definitions added hw/intc: GICv3 ITS command queue framework hw/intc: GICv3 ITS Command processing hw/intc: GICv3 ITS Feature enablement hw/intc: GICv3 redistributor ITS processing tests/data/acpi/virt: Add IORT files for ITS hw/arm/virt: add ITS support in virt GIC tests/data/acpi/virt: Update IORT files for ITS hw/arm/virt.c | 29 +- hw/intc/arm_gicv3.c | 14 + hw/intc/arm_gicv3_common.c | 13 + hw/intc/arm_gicv3_cpuif.c | 7 +- hw/intc/arm_gicv3_dist.c | 5 +- hw/intc/arm_gicv3_its.c | 1322 ++++++++++++++++++++++++ hw/intc/arm_gicv3_its_common.c | 7 +- hw/intc/arm_gicv3_its_kvm.c | 2 +- hw/intc/arm_gicv3_redist.c | 153 ++- hw/intc/gicv3_internal.h | 188 +++- hw/intc/meson.build | 1 + include/hw/arm/virt.h | 2 + include/hw/intc/arm_gicv3_common.h | 13 + include/hw/intc/arm_gicv3_its_common.h | 32 +- target/arm/kvm_arm.h | 4 +- tests/data/acpi/virt/IORT | Bin 0 -> 124 bytes tests/data/acpi/virt/IORT.memhp | Bin 0 -> 124 bytes tests/data/acpi/virt/IORT.numamem | Bin 0 -> 124 bytes tests/data/acpi/virt/IORT.pxb | Bin 0 -> 124 bytes 19 files changed, 1768 insertions(+), 24 deletions(-) create mode 100644 hw/intc/arm_gicv3_its.c create mode 100644 tests/data/acpi/virt/IORT create mode 100644 tests/data/acpi/virt/IORT.memhp create mode 100644 tests/data/acpi/virt/IORT.numamem create mode 100644 tests/data/acpi/virt/IORT.pxb --- 2.27.0
