[Qemu-devel] [PATCH v11 0/5] vGICv3 support |

This series introduces support for GICv3 by KVM. Software emulation is
currently not supported.
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
