2017-07-04include/exec/poison: Mark CONFIG_KVM as poisoned, tooThomas Huth
CONFIG_KVM is only defined for target-specific code, so nobody should use it by accident in common code. To avoid such subtle bugs, CONFIG_KVM is now marked as poisoned in common code. The header include/sysemu/kvm.h is somewhat special since it is included all over the place from common code, too, so we need some extra logic via "#ifdef NEED_CPU_H" here to make sure that we can compile all files without problems.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-05-17qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatableEduardo Habkost
cannot_instantiate_with_device_add_yet was introduced by commit efec3dd631d94160288392721a5f9c39e50fb2bc to replace no_user. It was supposed to be a temporary measure. When it was introduced, we had 54 cannot_instantiate_with_device_add_yet=true lines in the code. Today (3 years later) this number has not shrunk: we now have 57 cannot_instantiate_with_device_add_yet=true lines. I think it is safe to say it is not a temporary measure, and we won't see the flag go away soon. Instead of a long field name that misleads people to believe it is temporary, replace it a shorter and less misleading field: user_creatable. Except for code comments, changes were generated using the following Coccinelle patch: @@ expression DC; @@ ( -DC->cannot_instantiate_with_device_add_yet = false; +DC->user_creatable = true; | -DC->cannot_instantiate_with_device_add_yet = true; +DC->user_creatable = false; ) @@ typedef ObjectClass; expression dc; identifier class, data; @@ static void device_class_init(ObjectClass *class, void *data) { ... dc->hotpluggable = true; +dc->user_creatable = true; ... } @@ @@ struct DeviceClass { ... -bool cannot_instantiate_with_device_add_yet; +bool user_creatable; ... } @@ expression DC; @@ ( -!DC->cannot_instantiate_with_device_add_yet +DC->user_creatable | -DC->cannot_instantiate_with_device_add_yet +!DC->user_creatable ) Cc: Alistair Francis <alistair.francis@xilinx.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Thomas Huth <thuth@redhat.com> Acked-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Marcel Apfelbaum <marcel@redhat.com> Acked-by: Marcel Apfelbaum <marcel@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <20170503203604.31462-2-ehabkost@redhat.com> [ehabkost: kept "TODO remove once we're there" comment] Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2017-05-10hw/arm/virt: generate 64-bit addressable ACPI objectsArd Biesheuvel
Our current ACPI table generation code limits the placement of ACPI tables to 32-bit addressable memory, in order to be able to emit the root pointer (RSDP) and root table (RSDT) using table types from the ACPI 1.0 days. Since ARM was not supported by ACPI before version 5.0, it makes sense to lift this restriction. This is not crucial for mach-virt, which is guaranteed to have some memory available below the 4 GB mark, but it is a nice to have for QEMU machines that do not have any 32-bit addressable memory, which is not uncommon for real world 64-bit ARM systems. Since we already emit a version of the RSDP root pointer that has a secondary 64-bit wide address field for the 64-bit root table (XSDT), all we need to do is replace the RSDT generation with the generation of an XSDT table, and use a different slot in the FADT table to refer to the DSDT.

2017-03-01pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twiceIgor Mammedov
PCI hotplug for bridges was introduced only since 2.0 however acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL) didn't take in account that for legacy mode (1.7) when PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time. We managed to live with it only because of error rised by adding a duplicate property in acpi_set_bsel() has been ignored which resulted in useless leaking of just allocated (int)bus_bsel. Issue affects only 1.7 machine type as ACPI tables supported by QEMU were introduced at that time, but there wasn't PCI hotplug for bridges till the next release (2.0). Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info(). PS: do not ignore error returned by object_property_add_uint32_ptr() and abort QEMU since it's programming error which should be fixed instead of being ignored.
