This series introduces support for GICv3 by KVM. Software emulation is currently not supported.
Differences from v6: - Wrap own GIC type definitions on top of KVM ones. Fixed build on non-ARM-Linux hosts Differences from v5: - Fixed various checkpatch.pl style warnings - Removed TODO in gicv3_init_irqs_and_mmio(), relevant memory API patch included - gicv3_init_irqs_and_mmio() now takes 3 arguments instead of 4. It is more convenient to pass MMIO descriptors as array Differences from v4: - Do not reintroduce several constants shared with GICv2, reuse them instead. - Added gicv3_init_irqs_and_mmio() in base class, to be used by both software emulation and KVM code. Avoids code duplication. - Do not add NULL msi-parent phandle to PCI device in the FDT - Removed a couple of stale things from virt.c Differences from v3: - Fixed stupid build breakage in patch 0002 - Rebased on top of current master, patch 0003 adjusted according to kvm_irqchip_create() changes - Added assertion against uninitialized kernel_irqchip_type - Removed kernel_irqchip_type initialization from models which do not use KVM vGIC Differences from v2: - Removed some unrelated and unnecessary changes from virt machine, occasionally slipped in; some of them caused qemu to crash on ARM32. - Fixed build for ARM32; vGICv3 code requires definitions which are present only in ARM64 kernel Differences from v1: - Base class included, taken from the series by Shlomo Pongratz: http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01512.html The code is refactored as little as possible in order to simplify further addition of software emulation: - Minor fixes in code style and comments, according to old reviews - Removed REV_V3 definition because it's currently not used, and it does not add any meaning to number 3. - Removed reserved regions for MBI and ITS (except for 'virt' machine memory map). These should go to separate classes when implemented. - Improved commit messages - vGIC patches restructured - Use 'gicversion' option instead of virt-v3 machine Pavel Fedin (5): Merge memory_region_init_reservation() into memory_region_init_io() Extract some reusable vGIC code Introduce irqchip type specification for KVM Initial implementation of vGICv3 Add gicversion option to virt machine Shlomo Pongratz (1): Implement GIC-500 base class hw/arm/vexpress.c | 1 + hw/arm/virt.c | 140 +++++++++++++++++---- hw/intc/Makefile.objs | 4 + hw/intc/arm_gic_kvm.c | 84 ++++++------- hw/intc/arm_gicv3_common.c | 249 +++++++++++++++++++++++++++++++++++++ hw/intc/arm_gicv3_kvm.c | 155 +++++++++++++++++++++++ hw/intc/gicv3_internal.h | 156 +++++++++++++++++++++++ hw/intc/vgic_common.h | 43 +++++++ include/exec/memory.h | 14 ++- include/hw/arm/fdt.h | 2 +- include/hw/arm/virt.h | 6 +- include/hw/boards.h | 1 + include/hw/intc/arm_gicv3_common.h | 112 +++++++++++++++++ include/sysemu/kvm.h | 3 +- kvm-all.c | 2 +- memory.c | 10 +- stubs/kvm.c | 2 +- target-arm/kvm-consts.h | 6 + target-arm/kvm.c | 13 +- 19 files changed, 917 insertions(+), 86 deletions(-) create mode 100644 hw/intc/arm_gicv3_common.c create mode 100644 hw/intc/arm_gicv3_kvm.c create mode 100644 hw/intc/gicv3_internal.h create mode 100644 hw/intc/vgic_common.h create mode 100644 include/hw/intc/arm_gicv3_common.h -- 1.9.5.msysgit.0
