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 sbsa-ref platform as well as virt platform,wherein the emulated functionality co-exists with kvm kernel functionality. Changes in v7: - Restructured the lpi pending table scan logic as per comments in v6 - Addressed minor comments from v6 - For sbsa-ref platform,ITS memory map has been inserted between distributor & redistributors region similar to GIC-600 layout. Also, introduced sbsa-ref versioning to reflect the latest its memory map change and subsequent future use for helper functions - All kvm_unit_tests PASS - Verified Linux Boot functionality Shashi Mallela (10): 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 hw/arm/sbsa-ref: add ITS support in SBSA GIC 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/sbsa-ref.c | 79 +- hw/arm/virt.c | 28 +- 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 | 1298 ++++++++++++++++++++++++ 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 20 files changed, 1818 insertions(+), 28 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
