2017-12-05pci: Eliminate redundant PCIDevice::bus pointerDavid Gibson1-5/+5
The bus pointer in PCIDevice is basically redundant with QOM information. It's always initialized to the qdev_get_parent_bus(), the only difference is the type. Therefore this patch eliminates the field, instead creating a pci_get_bus() helper to do the type mangling to derive it conveniently from the QOM Device object underneath.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake1-1/+1
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.

2017-05-17sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICEEduardo Habkost1-0/+5
commit 33cd52b5d7b9adfd009e95f07e6c64dd88ae2a31 unset cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all sysbus devices appear on "-device help" and lack the "no-user" flag in "info qdm". To fix this, we can set user_creatable=false by default on TYPE_SYS_BUS_DEVICE, but this requires setting user_creatable=true explicitly on the sysbus devices that actually work with -device. Fortunately today we have just a few has_dynamic_sysbus=1 machines: virt, pc-q35-*, ppce500, and spapr. virt, ppce500, and spapr have extra checks to ensure just a few device types can be instantiated: * virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE. * ppce500 supports only TYPE_ETSEC_COMMON. * spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE. This patch sets user_creatable=true explicitly on those 4 device classes. Now, the more complex cases: pc-q35-*: q35 has no sysbus device whitelist yet (which is a separate bug). We are in the process of fixing it and building a sysbus whitelist on q35, but in the meantime we can fix the "-device help" and "info qdm" bugs mentioned above. Also, despite not being strictly necessary for fixing the q35 bug, reducing the list of user_creatable=true devices will help us be more confident when building the q35 whitelist. xen: We also have a hack at xen_set_dynamic_sysbus(), that sets has_dynamic_sysbus=true at runtime when using the Xen accelerator. This hack is only used to allow xen-backend devices to be dynamically plugged/unplugged. This means today we can use -device with the following 22 device types, that are the ones compiled into the qemu-system-x86_64 and qemu-system-i386 binaries: * allwinner-ahci * amd-iommu * cfi.pflash01 * esp * fw_cfg_io * fw_cfg_mem * generic-sdhci * hpet * intel-iommu * ioapic * isabus-bridge * kvmclock * kvm-ioapic * kvmvapic * SUNW,fdtwo * sysbus-ahci * sysbus-fdc * sysbus-ohci * unimplemented-device * virtio-mmio * xen-backend * xen-sysdev This patch adds user_creatable=true explicitly to those devices, temporarily, just to keep 100% compatibility with existing behavior of q35. Subsequent patches will remove user_creatable=true from the devices that are really not meant to user-creatable on any machine, and remove the FIXME comment from the ones that are really supposed to be user-creatable. This is being done in separate patches because we still don't have an obvious list of devices that will be whitelisted by q35, and I would like to get each device reviewed individually.

2017-05-17qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatableEduardo Habkost3-3/+3
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>

2017-02-06Allow ISA bus to be configured outDavid Gibson1-1/+1
Currently, the code to handle the legacy ISA bus is always included in qemu. However there are lots of platforms that don't include ISA legacy devies, and quite a few that have never used ISA legacy devices at all. This patch allows the ISA bus code to be disabled in the configuration for platforms where it doesn't make sense. For now, the default configs are adjusted to include ISA on all platforms including PCI: anything with PCI can at least in principle add an i82378 PCI->ISA bridge. Also, CONFIG_IDE_CORE which is already in pci.mak requires ISA support. We also explicitly enable ISA on some other non-PCI platforms which include ISA devices: moxie, sparc and unicore32. We may want to pare this down in future. The platforms that will lose ISA by default are: cris, lm32, microblazeel, microblaze, openrisc, s390x, tricore, xtensaeb, xtensa. As far as I can tell none of these ever used ISA. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Michael S.

2017-01-27hw/isa/lpc_ich9: add broadcast SMI featureLaszlo Ersek1-1/+9
The generic edk2 SMM infrastructure prefers EFI_SMM_CONTROL2_PROTOCOL.Trigger() to inject an SMI on each processor. If Trigger() only brings the current processor into SMM, then edk2 handles it in the following ways: (1) If Trigger() is executed by the BSP (which is guaranteed before ExitBootServices(), but is not necessarily true at runtime), then: (a) If edk2 has been configured for "traditional" SMM synchronization, then the BSP sends directed SMIs to the APs with APIC delivery, bringing them into SMM individually. Then the BSP runs the SMI handler / dispatcher. (b) If edk2 has been configured for "relaxed" SMM synchronization, then the APs that are not already in SMM are not brought in, and the BSP runs the SMI handler / dispatcher. (2) If Trigger() is executed by an AP (which is possible after ExitBootServices(), and can be forced e.g. by "taskset -c 1 efibootmgr"), then the AP in question brings in the BSP with a directed SMI, and the BSP runs the SMI handler / dispatcher. The smaller problem with (1a) and (2) is that the BSP and AP synchronization is slow. For example, the "taskset -c 1 efibootmgr" command from (2) can take more than 3 seconds to complete, because efibootmgr accesses non-volatile UEFI variables intensively. The larger problem is that QEMU's current behavior diverges from the behavior usually seen on physical hardware, and that keeps exposing obscure corner cases, race conditions and other instabilities in edk2, which generally expects / prefers a software SMI to affect all CPUs at once. Therefore introduce the "broadcast SMI" feature that causes QEMU to inject the SMI on all VCPUs. While the original posting of this patch <http://lists.nongnu.org/archive/html/qemu-devel/2015-10/msg05658.html> only intended to speed up (2), based on our recent "stress testing" of SMM this patch actually provides functional improvements.

2017-01-27hw/isa/lpc_ich9: add SMI feature negotiation via fw_cfgLaszlo Ersek1-0/+79
Introduce the following fw_cfg files: - "etc/smi/supported-features": a little endian uint64_t feature bitmap, presenting the features known by the host to the guest. Read-only for the guest. The content of this file will be determined via bit-granularity ICH9-LPC device properties, to be introduced later. For now, the bitmask is left zeroed. The bits will be set from machine type compat properties and on the QEMU command line, hence this file is not migrated. - "etc/smi/requested-features": a little endian uint64_t feature bitmap, representing the features the guest would like to request. Read-write for the guest. The guest can freely (re)write this file, it has no direct consequence. Initial value is zero. A nonzero value causes the SMI-related fw_cfg files and fields that are under guest influence to be migrated. - "etc/smi/features-ok": contains a uint8_t value, and it is read-only for the guest. When the guest selects the associated fw_cfg key, the guest features are validated against the host features. In case of error, the negotiation doesn't proceed, and the "features-ok" file remains zero. In case of success, the "features-ok" file becomes (uint8_t)1, and the negotiated features are locked down internally (to which no further changes are possible until reset). The initial value is zero. A nonzero value causes the SMI-related fw_cfg files and fields that are under guest influence to be migrated. The C-language fields backing the "supported-features" and "requested-features" files are uint8_t arrays. This is because they carry guest-side representation (our choice is little endian), while VMSTATE_UINT64() assumes / implies host-side endianness for any uint64_t fields. If we migrate a guest between hosts with different endiannesses (which is possible with TCG), then the host-side value is preserved, and the host-side representation is translated. This would be visible to the guest through fw_cfg, unless we used plain byte arrays. So we do. Cc: "Michael S.

2016-06-29ICH9 LPC: move call of isa_bus_irqs to 'realize' methodEfimov Vasily1-0/+2
The isa_bus_irqs function initializes ISA bus IRQ array pointer with specified value. Previously the ICH9 LPC bridge model did not have its own IRQs but only IRQ pointer cache. And same GSI were used for ISA bus and other sources behind the bridge (PCI, SCI). Hence, the pc_q35_init was only possible place to setup both ISA bus IRQs and the bridge IRQ cache. As a result, the call of isa_bus_irqs was made from pc_q35_init. Now the ICH9 LPC bridge has its own output IRQs which are connected to GSI. The output IRQs are already used to route IRQs from PCI and SCI. The patch makes the ICH9 LPC bridge output IRQs to used for ISA bus too.
