acpi_data_push uses g_array_set_size to resize the memory size. If there is no enough contiguous memory, the address will be changed. So previous pointer could not be used any more. It must update the pointer and use the new one. Also, previous codes wrongly use le32 conversion of iort->node_offset for subsequent computations that will result incorrect value if host is not litlle endian. So use the non-converted one instead.

2018-05-31arm: fix qemu crash on startup with -bios optionIgor Mammedov
When QEMU is started with following CLI -machine virt,gic-version=3,accel=kvm -cpu host -bios AAVMF_CODE.fd it crashes with abort at accel/kvm/kvm-all.c:2164: KVM_SET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c665: Invalid argument Which is caused by implicit dependency of kvm_arm_gicv3_reset() on arm_gicv3_icc_reset() where the later is called by CPU reset reset callback. However commit: 3b77f6c arm/boot: split load_dtb() from arm_load_kernel() broke CPU reset callback registration in case arm_load_kernel() ... if (!info->kernel_filename || info->firmware_loaded) branch is taken, i.e. it's sufficient to provide a firmware or do not provide kernel on CLI to skip cpu reset callback registration, where before offending commit the callback has been registered unconditionally. Fix it by registering the callback right at the beginning of arm_load_kernel() unconditionally instead of doing it at the end. NOTE: we probably should eliminate that dependency anyways as well as separate arch CPU reset parts from arm_load_kernel() into CPU itself, but that refactoring that I probably would have to do anyways later for CPU hotplug to work.

2018-05-18hw/arm/smmuv3: Fix Coverity issue in smmuv3_record_eventEric Auger
Coverity complains about use of uninitialized Evt struct. The EVT_SET_TYPE and similar setters use deposit32() on fields in the struct, so they read the uninitialized existing values. In cases where we don't set all the fields in the event struct we'll end up leaking random uninitialized data from QEMU's stack into the guest. Initializing the struct with "Evt evt = {};" ought to satisfy Coverity and fix the data leak.

2018-05-10arm/boot: split load_dtb() from arm_load_kernel()Igor Mammedov
load_dtb() depends on arm_load_kernel() to figure out place in RAM where it should be loaded, but it's not required for arm_load_kernel() to work. Sometimes it's neccesary for devices added with -device/device_add to be enumerated in DTB as well, which's lead to [1] and surrounding commits to add 2 more machine_done notifiers with non obvious ordering to make dynamic sysbus devices initialization happen in the right order. However instead of moving whole arm_load_kernel() in to machine_done, it's sufficient to move only load_dtb() into virt_machine_done() notifier and remove ArmLoadKernelNotifier/ /PlatformBusFDTNotifierParams notifiers, which saves us ~90LOC and simplifies code flow quite a bit. Later would allow to consolidate DTB generation within one function for 'mach-virt' board and make it reentrant so it could generate updated DTB in device hotplug secenarios. While at it rename load_dtb() to arm_load_dtb() since it's public now. Add additional field skip_dtb_autoload to struct arm_boot_info to allow manual DTB load later in mach-virt and to avoid touching all other boards to explicitly call arm_load_dtb(). 1) (ac9d32e hw/arm/boot: arm_load_kernel implemented as a machine init done notifier) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Andrew Jones <drjones@redhat.com> Message-id: 1525691524-32265-4-git-send-email-imammedo@redhat.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2018-05-10platform-bus-device: use device plug callback instead of machine_done notifierIgor Mammedov
platform-bus were using machine_done notifier to get and map (assign irq/mmio resources) dynamically added sysbus devices after all '-device' options had been processed. That however creates non obvious dependencies on ordering of machine_done notifiers and requires carefull line juggling to keep it working. For example see comment above create_platform_bus() and 'straitforward' arm_load_kernel() had to converted to machine_done notifier and that lead to yet another machine_done notifier to keep it working arm_register_platform_bus_fdt_creator(). Instead of hiding resource assignment in platform-bus-device to magically initialize sysbus devices, use device plug callback and assign resources explicitly at board level at the moment each -device option is being processed. That adds a bunch of machine declaration boiler plate to e500plat board, similar to ARM/x86 but gets rid of hidden machine_done notifier and would allow to remove the dependent notifiers in ARM code simplifying it and making code flow easier to follow.

That's not how the "default" devices in vl.c are meant to work - it should be possible for a board to also start up without default devices. So let's turn the error message and exit() into a warning instead.

2018-05-04arm: boot: set boot_info starting from first_cpuIgor Mammedov
Even though nothing is currently broken (since all boards use first_cpu as boot cpu), make sure that boot_info is set on all CPUs. If some board would like support heterogenuos setup (i.e. init boot_info on subset of CPUs) in future, it should add a reasonable API to do it, instead of starting assigning boot_info from some CPU and till the end of present CPUs list.

2018-05-04hw/arm/virt: Add linux,pci-domain propertyJan Kiszka
This allows to pin the host controller in the Linux PCI domain space. Linux requires that property to be available consistently or not at all, in which case the domain number becomes unstable on additions/removals. Adding it here won't make a difference in practice for most setups as we only expose one controller. However, enabling Jailhouse on top may introduce another controller, and that one would like to have stable address as well. So the property is needed for the first controller as well.

2018-04-26hw/arm/aspeed_soc: don't use vmstate_register_ram_global for SRAMPeter Maydell
Currently we use vmstate_register_ram_global() for the SRAM; this is not a good idea for devices, because it means that you can only ever create one instance of the device, as the second instance would get a RAM block name clash. Instead, use memory_region_init_ram(), which automatically registers the RAM block with a local-to-the-device name. Note that this would be a cross-version migration compatibility break for the "palmetto-bmc", "ast2500-evb" and "romulus-bmc" machines, but migration is currently broken for them.

2018-04-26hw/arm/raspi: Don't bother setting default_cpu_typePeter Maydell
In commit 210f47840dd62, we changed the bcm2836 SoC object to always create a CPU of the correct type for that SoC model. This makes the default_cpu_type settings in the MachineClass structs for the raspi2 and raspi3 boards redundant. We didn't change those at the time because it would have meant a temporary regression in a corner case of error handling if the user requested a non-existing CPU type. The -cpu parse handling changes in 2278b93941d42c3 mean that it no longer implicitly depends on default_cpu_type for this to work, so we can now delete the redundant default_cpu_type fields.

2018-04-26arm: always start from first_cpu when registering loader cpu reset callbackIgor Mammedov
if arm_load_kernel() were passed non first_cpu, QEMU would end up with partially set do_cpu_reset() callback leaving some CPUs without it. Make sure that do_cpu_reset() is registered for all CPUs by enumerating CPUs from first_cpu.

2018-04-10hw/arm/allwinner-a10: Do not use nd_table in instance_init functionThomas Huth
The instance_init function of a device can be called at any time, even if the device is not going to be used (i.e. not going to be realized). So a instance_init function must not do things that could cause QEMU to exit, like calling qemu_check_nic_model(&nd_table[0], ...) for example. But this is what the instance_init function of the allwinner-a10 device is currently doing - and this causes QEMU to quit unexpectedly when you run the 'device-list-properties' QMP command for example: $ echo "{'execute':'qmp_capabilities'}"\ "{'execute':'device-list-properties',"\ " 'arguments':{'typename':'allwinner-a10'}}" \ | arm-softmmu/qemu-system-arm -M mps2-an505,accel=qtest -qmp stdio {"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2}, "package": "build-all"}, "capabilities": []}} {"return": {}} Unsupported NIC model: lan9118 ... and QEMU quits after printing the last line (which should not happen just because of running 'device-list-properties' here). And with the cubieboard, this even causes QEMU to abort(): $ echo "{'execute':'qmp_capabilities'}"\ "{'execute':'device-list-properties',"\ " 'arguments':{'typename':'allwinner-a10'}}" \ | arm-softmmu/qemu-system-arm -M cubieboard,accel=qtest -qmp stdio {"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2}, "package": "build-all"}, "capabilities": []}} {"return": {}} Unexpected error in error_set_from_qdev_prop_error() at hw/core/qdev-properties.c:1095: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use Aborted (core dumped) To fix the problem we've got to move the offending code to the realize function instead.

An instance_init function must not fail - and might be called multiple times, e.g. during device introspection with the 'device-list-properties' QMP command.
