This series introduces support for GICv3 by KVM. Software emulation is currently not supported.
This patchset applies on top of: http://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg00518.html v7 => v8 - Removed all unused SW emulation code - Removed unnecessary attributes from common class - Set "non-migratable" flag for GICv3 device - Removed unnecessary conditions from kvm_arm_gicv3_realize() - Fixed GIC type setting in vexpress model, was done in wrong place - Cleaned up virt machine memory map v6 => v7 - Wrap own GIC type definitions on top of KVM ones. Fixed build on non-ARM-Linux hosts v5 => v6 - 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 v4 => v5 - 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 v3 => v4 - 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 v2 => v3 - 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 v1 => v2 - 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 (4): 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 | 3 + hw/arm/virt.c | 135 +++++++++++++++++++++++++++++----- hw/intc/Makefile.objs | 2 + hw/intc/arm_gic_kvm.c | 84 ++++++++++----------- hw/intc/arm_gicv3_common.c | 147 +++++++++++++++++++++++++++++++++++++ hw/intc/arm_gicv3_kvm.c | 143 ++++++++++++++++++++++++++++++++++++ hw/intc/vgic_common.h | 43 +++++++++++ include/hw/arm/fdt.h | 2 +- include/hw/arm/virt.h | 5 +- include/hw/boards.h | 1 + include/hw/intc/arm_gicv3_common.h | 70 ++++++++++++++++++ include/sysemu/kvm.h | 3 +- kvm-all.c | 2 +- stubs/kvm.c | 2 +- target-arm/kvm-consts.h | 6 ++ target-arm/kvm.c | 13 +++- 16 files changed, 590 insertions(+), 71 deletions(-) create mode 100644 hw/intc/arm_gicv3_common.c create mode 100644 hw/intc/arm_gicv3_kvm.c create mode 100644 hw/intc/vgic_common.h create mode 100644 include/hw/intc/arm_gicv3_common.h -- 1.9.5.msysgit.0
