Hi All. This series aims to add GICv3 support to the New VGIC. It adds support for the GICv3 distributor, redistributor, sysreg and ITS interfaces. This will allow Xen to emulate level-triggered interrupts with GICv3 and will make the NEW_VGIC more complete and usable. The series also introduces some refactoring of the ITS code to allow for easier VITS implementation switching. The bulk of the code is taken from the Linux Kernel v6.0 and adapted to the existing Xen codebase. Changes in v2: - Split changes into smaller pieces similar to new VGIC v2 patches - Refactor some common code to remove ifdefs - Remove the "move get/put irq" change as it is no longer needed - Replace GICD base change with proper offset calculation - Fixed Kconfig dependencies Mykyta Poturai (25): arm: vgic: its: Decouple HW and virtual ITS arm: new VGIC: Add GICv3 world switch backend arm: new VGIC: Add GICv3 MMIO handling framework arm: new VGIC: Add GICv3 CTLR, IIDR, TYPER handlers arm: new VGIC: Add GICv3 redistributor IIDR and TYPER handler arm: new VGIC: Add GICv3 IDREGS register handler arm: new VGIC: Add GICv3 IROUTER register handlers arm: new VGIC: Add GICv3 SGI system register trap handler arm: new VGIC: vgic_init: implement map_resources arm: new VGIC: Add vgic_v3_enable arm: new VGIC: Add alternative redist region storage arm: new VGIC: Wire new GICv3 into the build system arm: new VGIC: Handle ITS related GICv3 redistributor registers arm: new VGIC: its: Introduce ITS emulation file with MMIO framework arm: new VGIC: its: Introduce ITS device list arm: new VGIC: its: Implement basic ITS register handlers arm: new VGIC: its: Read initial LPI pending table arm: new VGIC: its: Allow updates of LPI configuration table arm: new VGIC: its: Add LPI translation cache definition arm: new VGIC: its: Implement ITS command queue command handlers arm: new VGIC: its: Implement MSI injection in ITS emulation arm: new VGIC: its: Implement MMIO-based LPI invalidation arm: new VGIC: its: Enable ITS emulation as a virtual MSI controller arm: new VGIC: its: Wire new ITS into the build system arm: new VGIC: Improve MMIO handling xen/arch/arm/Kconfig | 5 +- xen/arch/arm/gic-v3-its.c | 208 +-- xen/arch/arm/gic-v3-lpi.c | 20 - xen/arch/arm/include/asm/gic_v3_defs.h | 13 +- xen/arch/arm/include/asm/gic_v3_its.h | 82 + xen/arch/arm/include/asm/new_vgic.h | 93 +- xen/arch/arm/include/asm/vgic.h | 29 + xen/arch/arm/vgic-v3-its.c | 206 ++- xen/arch/arm/vgic/Makefile | 3 + xen/arch/arm/vgic/vgic-init.c | 24 +- xen/arch/arm/vgic/vgic-its.c | 2022 ++++++++++++++++++++++++ xen/arch/arm/vgic/vgic-mmio-v3.c | 1095 +++++++++++++ xen/arch/arm/vgic/vgic-mmio.c | 19 +- xen/arch/arm/vgic/vgic-mmio.h | 38 + xen/arch/arm/vgic/vgic-v3.c | 305 ++++ xen/arch/arm/vgic/vgic.c | 41 +- xen/arch/arm/vgic/vgic.h | 54 +- 17 files changed, 4015 insertions(+), 242 deletions(-) create mode 100644 xen/arch/arm/vgic/vgic-its.c create mode 100644 xen/arch/arm/vgic/vgic-mmio-v3.c create mode 100644 xen/arch/arm/vgic/vgic-v3.c -- 2.34.1
