2017-09-14hmp: introduce 'info memory_size_summary' commandVadim Galitsyn
Add 'info memory_size_summary' command which is a sibling of QMP command query-memory-size-summary. It provides the following memory information in bytes: * base-memory - size of "base" memory specified with command line option -m. * plugged-memory - amount of memory that was hot-plugged. If target does not have CONFIG_MEM_HOTPLUG enabled, no value is reported.

Some termcaps (found using SLES11SP1) use [? sequences. According to man console_codes (http://linux.die.net/man/4/console_codes) the question mark is a nop and should simply be ignored.

2017-09-08vmgenid: replace x-write-pointer-available hackMarc-André Lureau
This compat property sole function is to prevent the device from being instantiated. Instead of requiring an extra compat property, check if fw_cfg has DMA enabled. fw_cfg is a built-in device that is initialized very early by the machine init code. We have at least one other device that also assumes fw_cfg_find() can be safely used on realize: pvpanic. This has the additional benefit of handling other cases properly, like: $ qemu-system-x86_64 -device vmgenid -machine none qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.9 -global fw_cfg.dma_enabled=off qemu-system-x86_64: -device vmgenid: vmgenid requires DMA write support in fw_cfg, which this machine type does not provide $ qemu-system-x86_64 -device vmgenid -machine pc-i440fx-2.6 -global fw_cfg.dma_enabled=on [boots normally] Suggested-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.

2017-09-08hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root PortAleksandr Bezzubikov
To enable hotplugging of a newly created pcie-pci-bridge, we need to tell firmware (e.g. SeaBIOS) to reserve additional buses or IO/MEM/PREF space for pcie-root-port. Additional bus reservation allows us to hotplug pcie-pci-bridge into this root port. The number of buses and IO/MEM/PREF space to reserve are provided to the device via a corresponding property, and to the firmware via new PCI capability. The properties' default values are -1 to keep default behavior unchanged.

2017-09-08Revert "ACPI: don't call acpi_pcihp_device_plug_cb on xen"Anthony PERARD
This reverts commit 153eba4726dfa1bdfc31d1fe973b2a61b9035492. This patch prevents PCI passthrough hotplug on Xen. Even if the Xen tool stack prepares its own ACPI tables, we still rely on QEMU for hotplug ACPI notifications. The original issue is fixed by the two previous patch: hw/acpi: Limit hotplug to root bus on legacy mode hw/acpi: Move acpi_set_pci_info to pcihp Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Reviewed-by: Michael S.

2017-09-08hw/acpi: Move acpi_set_pci_info to pcihpAnthony PERARD
HW part of ACPI PCI hotplug in QEMU depends on ACPI_PCIHP_PROP_BSEL being set on a PCI bus that supports ACPI hotplug. It should work regardless of the source of ACPI tables (QEMU generator/legacy SeaBIOS/Xen). So move ACPI_PCIHP_PROP_BSEL initialization into HW ACPI implementation part from QEMU's ACPI table generator. To do PCI passthrough with Xen, the property ACPI_PCIHP_PROP_BSEL needs to be set, but this was done only when ACPI tables are built which is not needed for a Xen guest. The need for the property starts with commit "pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twice" (f0c9d64a68b776374ec4732424a3e27753ce37b6). Adding find_i440fx into stubs so that mips-softmmu target can be built.

2017-09-08vhost: Release memory references on cleanupAlex Williamson
vhost registers a MemoryListener where it adds and removes references to MemoryRegions as the MemoryRegionSections pass through. The region_add callback is invoked for each existing section when the MemoryListener is registered, but unregistering the MemoryListener performs no reciprocal region_del callback. It's therefore the owner of the MemoryListener's responsibility to cleanup any persistent changes, such as these memory references, after unregistering. The consequence of this bug is that if we have both a vhost device and a vfio device, the vhost device will reference any mmap'd MMIO of the vfio device via this MemoryListener. If the vhost device is then removed, those references remain outstanding. If we then attempt to remove the vfio device, it never gets finalized and the only way to release the kernel file descriptors is to terminate the QEMU process.
