This patch series enables machvirt to dynamically instantiate sysbus devices from command line (using -device option). It applies on top of Alex Graf's series - "Dynamic sysbus device allocation support" http://lists.gnu.org/archive/html/qemu-ppc/2014-07/msg00047.html and transposes the work done for PPC e500 on machvirt. The code related to dynamic sysbus device IRQ/mmio region binding, originally located in PPC e500.c, is moved into hw/misc/dyn_sysbus_binding new module for ARM only, the code related to device tree node generation is moved into hw/arm/dyn_sysbus_devtree module. Both e500 and machvirt are adapted to use dyn_sysbus_binding helper routines. integrated branch can be found on http://git.linaro.org/people/eric.auger/qemu.git, branch vfio_integ_v6 A related discussion can be found at https://lists.nongnu.org/archive/html/qemu-devel/2014-07/msg04065.html For e500 the device tree generation is kept in the machine file, according to Alex will. For machvirt we use dyn_sysbus_devtree since the code becomes large with the expected support of vfio devices. Best Regards Eric v2 -> v3: - patch now applies on top of Alex full patchset - dyn_sysbus_devtree: add arm_prefix to emphasize the fact those functions are arm specific; arm_sysbus_device_create_devtree becomes static - load_dtb renamed into arm_load_dtb - add copyright in hw/arm/dyn_sysbus_devtree.c v1 -> v2: - device node generation no more in sysbus device but in dyn_sysbus_devtree - VFIO region shrinked to 4MB and relocated in machvirt to avoid PCI shrink (dynamic vfio-mmio support might come latter) - platform_bus_base removed from PlatformDevtreeData Alexander Graf (1): PPC: e500: use dyn_sysbus_binding helper routines Eric Auger (5): hw/misc/dyn_sysbus_binding: helpers for sysbus device dynamic binding hw/arm/dyn_sysbus_devtree: helpers for sysbus device dynamic dt node generation hw/arm/boot: load_dtb becomes non static arm_load_dtb hw/arm/virt: new add_fdt_*_node functions hw/arm/virt: Support dynamically spawned sysbus devices hw/arm/Makefile.objs | 1 + hw/arm/boot.c | 4 +- hw/arm/dyn_sysbus_devtree.c | 92 ++++++++++++++++++ hw/arm/virt.c | 129 +++++++++++++++++++----- hw/misc/Makefile.objs | 1 + hw/misc/dyn_sysbus_binding.c | 163 +++++++++++++++++++++++++++++++ hw/ppc/e500.c | 183 +++-------------------------------- hw/ppc/e500.h | 7 +- hw/ppc/e500plat.c | 13 ++- include/hw/arm/arm.h | 1 + include/hw/arm/dyn_sysbus_devtree.h | 16 +++ include/hw/misc/dyn_sysbus_binding.h | 24 +++++ 12 files changed, 426 insertions(+), 208 deletions(-) create mode 100644 hw/arm/dyn_sysbus_devtree.c create mode 100644 hw/misc/dyn_sysbus_binding.c create mode 100644 include/hw/arm/dyn_sysbus_devtree.h create mode 100644 include/hw/misc/dyn_sysbus_binding.h -- 1.8.3.2 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
