2015-07-08hw/i386/pc: don't carry FDC from pc_basic_device_init() to pc_cmos_init()Laszlo Ersek
Thanks to the last patch, pc_cmos_init() doesn't need the (optional) board-default FDC any longer as an input parameter. Update pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(), and update the latter not to carry the FDC to pc_cmos_init(). This simplifies the code. pc_init1() | pc_q35_init() pc_basic_device_init() pc_cmos_init() Cc: Jan Tomko <jtomko@redhat.com> Cc: John Snow <jsnow@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Michael S.

2015-07-08ich9: implement strap SPKR pin logicPaulo Alcantara
If the signal is sampled high, this indicates that the system is strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system reboot feature). The status of this strap is readable via the NO_REBOOT bit (CC: offset 0x3410:bit 5). The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit may be set or cleared by software if the strap is sampled low but may not override the strap when it indicates "No Reboot". This patch implements the logic where hardware has ability to set SPKR pin through a property named "noreboot" and it's sampled high by default.

2015-07-07xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabledBharata B Rao
When supporting CPU hot removal by parking the vCPU fd and reusing it during hotplug again, there can be cases where we try to reenable KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled. Introduce a boolean member in ICPState to track this and don't reenable the CAP if it was already enabled earlier. Re-enabling this CAP should ideally work, but currently it results in kernel trying to create and associate ICP with this vCPU and that fails since there is already an ICP associated with it. Hence this patch is needed to work around this problem in the kernel. This change allows CPU hot removal to work for sPAPR.

The sPAPRMachineState structure includes an entry_point field containing the initial PC value for starting the machine, even though this always has the value 0x100.

2015-07-07spapr: Remove obsolete ram_limit field from sPAPRMachineStateDavid Gibson
The ram_limit field was imported from sPAPREnvironment where it predates the machine's ram size being available generically from machine->ram_size. Worse, the existing code was inconsistent about where it got the ram size from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size' and sometimes a local 'ram_size' masking the global. This cleans up the code to consistently use machine->ram_size, eliminating spapr->ram_limit in the process.

2015-07-07spapr: Merge sPAPREnvironment into sPAPRMachineStateDavid Gibson
The code for -machine pseries maintains a global sPAPREnvironment structure which keeps track of general state information about the guest platform. This predates the existence of the MachineState structure, but performs basically the same function. Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState. This is mostly a matter of search and replace, although a few places which relied on the global spapr variable are changed to find the structure via qdev_get_machine().

2015-07-07ich9: add TCO interface emulationPaulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

2015-07-07vl: move rom_load_all after machine init doneEric Auger
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the memory preparation for boot until the machine init done notifier. This has for consequence to insert ROM at machine init done time. However the rom_load_all function stayed called before the ROM are inserted. As a consequence the rom_load_all function does not do everything it is expected to do, on ARM. It currently registers the ROM reset notifier but does not iterate through the registered ROM list. the isrom field is not set properly. This latter is used to report info in the monitor and also to decide whether the rom->data can be freed on ROM reset notifier. To fix that regression the patch moves the rom_load_all call after machine init done. We also take the opportunity to rename the rom_load_all function into rom_check_and_resgister_reset() and integrate the rom_load_done in it.

The T5 hardware has a bug in it where it reports a Pending Interrupt Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead of the 0x1000 that the hardware actually uses internally. As the hardware doesn't return the correct pba_offset value, add a quirk to instead return a hardcoded value of 0x1000 when a Chelsio T5 VF device is detected. This bug has been fixed in the Chelsio's next chip series T6 but there are no plans to respin the T5 ASIC for this bug. It is just documented in the T5 Errata and left it at that.

2015-07-06Stop including qemu-common.h in memory.hPeter Maydell
Including qemu-common.h from other header files is generally a bad idea, because it means it's very easy to end up with a circular dependency. For instance, if we wanted to include memory.h from qom/cpu.h we'd end up with this loop: memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h Remove the include from memory.h. This requires us to fix up a few other files which were inadvertently getting declarations indirectly through memory.h. The biggest change is splitting the fprintf_function typedef out into its own header so other headers can get at it without having to include qemu-common.h.

2015-06-23hw/core: explicit OFW unit address callback for SysBusDeviceClassLaszlo Ersek
The sysbus_get_fw_dev_path() function formats OpenFirmware device path nodes ("driver-name@unit-address") for sysbus devices. The first choice for "unit-address" is the base address of the device's first MMIO region. The second choice is its first IO port. However, if two sysbus devices with the same "driver-name" lack both MMIO and PIO resources, then there is no good way to distinguish them based on their OFW nodes, because in this case unit-address is omitted completely for both devices. An example is TYPE_PXB_HOST ("pxb-host"). For the sake of such devices, introduce the explicit_ofw_unit_address() "virtual member function". With this function, each sysbus device in the same SysBusDeviceClass can state its own address. Cc: Markus Armbruster <armbru@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

2015-06-23balloon: add a feature bit to let Guest OS deflate balloon on oomDenis V. Lunev
Excessive virtio_balloon inflation can cause invocation of OOM-killer, when Linux is under severe memory pressure. Various mechanisms are responsible for correct virtio_balloon memory management. Nevertheless it is often the case that these control tools does not have enough time to react on fast changing memory load. As a result OS runs out of memory and invokes OOM-killer. The balancing of memory by use of the virtio balloon should not cause the termination of processes while there are pages in the balloon. Now there is no way for virtio balloon driver to free memory at the last moment before some process get killed by OOM-killer. This does not provide a security breach as balloon itself is running inside Guest OS and is working in the cooperation with the host. Thus some improvements from Guest side should be considered as normal. To solve the problem, introduce a virtio_balloon callback which is expected to be called from the oom notifier call chain in out_of_memory() function. If virtio balloon could release some memory, it will make the system return and retry the allocation that forced the out of memory killer to run. This behavior should be enabled if and only if appropriate feature bit is set on the device. It is off by default. This functionality was recently merged into vanilla Linux. commit 5a10b7dbf904bfe01bb9fcc6298f7df09eed77d5 Author: Raushaniya Maksudova <rmaksudova@parallels.com> Date: Mon Nov 10 09:36:29 2014 +1030 This patch adds respective control bits into QEMU.

This allows to assign host input devices to the guest: qemu -device virtio-input-host-pci,evdev=/dev/input/event<nr> The guest gets exclusive access to the input device, so be careful with assigning the keyboard if you have only one connected to your machine.

2015-06-23virtio-input: move properties, use virtio_instance_init_commonGerd Hoffmann
Move properties from virtio-*-pci to virtio-*-device. Also make better use of QOM and attach common properties to the abstract parent classes (virtio-input-device and virtio-input-pci-device). Switch the hid device instance init functions over to use virtio_instance_init_common, so we get the properties of the virtio device aliased properly to the virtio pci proxy.

2015-06-19qdev: Deprecated qdev_init() is finally unused, dropMarkus Armbruster
qdev_init() is a wrapper around setting property "realized" to true, plus error handling that passes errors to qerror_report_err(). qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. All code has been modernized to avoid qdev_init() and its inappropriate error handling. We can finally drop it.

2015-06-19vhost: enable vhost without without MSI-XPankaj Gupta
We use vhostforce to enable vhost even if Guests don't have MSI-X support and we fall back to QEMU virtio-net. This gives a very small performance gain, but the disadvantage is that guest now controls which virtio code is running (qemu or vhost) so our attack surface is doubled. This patch will enable vhost unconditionally whenever it's requested. For compatibility, enable vhost when vhostforce is set, as well.
