This series introduces support for GICv3 by KVM. Software emulation is currently not supported.
v13 => v14 - Rebased on the latest master, fixed conflicts in hw/arm/virt.c v12 => v13 - Many stylistic fixes - Fixed up ACPI data for virt machine - Added gic-version=host value which probes for best possible vGIC version - Reserved regions for memory-mapped CPU/vCPU/HYP interfaces - Maximum number of CPUs for virt machine dropped to 123 (memory map limitation) v11 => v12 - Do not set timer PPI CPU mask in device tree for GICv3 - Fixed small styling issues in hw/arm/virt.c - Completely untied kvm_gic_access() from GIC and turned into kvm_device_access(). Attribute mapping is now handled in gicd/gicc wrapper macros. v11 => v10 - Fixed minor issues with checkpatch and comments, reported by Eric Auger - Make reusable kvm_gic_supports_attr(), moved to kvm-all.c and renamed as kvm_device_check_attr(). Useful for future live migration. v9 => v10 - Renamed "gicversion" option to "gic-version" (was forgotten in v9) - Data pointer in kvm_gic_access() is now void * because in case of vGICv3 this function is expected to operate on 64-bit registers too (GICD_IROUTER for instance) v8 => v9 - Removed all limitations on CPU and IRQ number from the base class - Added back missing properties, interface is now the same as in GICv2 - Refactored reusable parts of vGICv2 code, decreased number of changes - Removed GIC type check from kvm_arch_irqchip_create(), no more need to specify GIC type early - Fixed up all commit messages / logs - Removed 'nvic' field assignment in virt machine (was forgotten in v8) - CPU number limitation for 'virt' machine now comes from memory map (how many redistributors can be placed). With current layout it appears to be 126. v7 => v8 - Removed all unused SW emulation code - Removed unnecessary attributes from common class - Set "unmigratable" flag for GICv3 device - Removed unnecessary conditions from kvm_arm_gicv3_realize() - Fixed GIC type setting in vexpress model, was done in wrong place - Fixed condition style in hw/intc/Makefile.objs - 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): intc/gic: Extract some reusable vGIC code arm_kvm: Do not assume particular GIC type in kvm_arch_irqchip_create() hw/intc: Initial implementation of vGICv3 hw/arm/virt: Add gic-version option to virt machine Shlomo Pongratz (1): hw/intc: Implement GIC-500 base class hw/arm/virt-acpi-build.c | 54 ++++++++------ hw/arm/virt.c | 124 ++++++++++++++++++++++++------ hw/intc/Makefile.objs | 2 + hw/intc/arm_gic_kvm.c | 98 ++++++++---------------- hw/intc/arm_gicv3_common.c | 140 ++++++++++++++++++++++++++++++++++ hw/intc/arm_gicv3_kvm.c | 149 +++++++++++++++++++++++++++++++++++++ hw/intc/vgic_common.h | 35 +++++++++ include/hw/acpi/acpi-defs.h | 9 +++ include/hw/arm/virt-acpi-build.h | 1 + include/hw/arm/virt.h | 4 +- include/hw/intc/arm_gicv3_common.h | 68 +++++++++++++++++ include/sysemu/kvm.h | 26 +++++++ kvm-all.c | 34 +++++++++ target-arm/kvm.c | 19 +++-- target-arm/kvm_arm.h | 19 +++++ target-arm/machine.c | 18 +++++ 16 files changed, 682 insertions(+), 118 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 -- 2.4.4
