2015-07-07Fix the compatibility typedef of ioservid_t to match the Xen headersPaul Durrant
There is a mismatch between the definition of ioservid_t in xen_common.h and the definition in the Xen publix headers. This patch corrects the definition in xen_common.h. Signed-off-by: Paul Durrant <paul.durrant@citrix.com> Cc: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

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().

2015-07-07ich9: 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.

2015-07-07ich9: 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.

2015-07-06Stop 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.

2015-07-01main-loop: introduce qemu_mutex_iothread_lockedPaolo Bonzini
This function will be used to avoid recursive locking of the iothread lock whenever address_space_rw/ld*/st* are called with the BQL held, which is almost always the case. Tracking whether the iothread is owned is very cheap (just use a TLS variable) but requires some care because now the lock must always be taken with qemu_mutex_lock_iothread(). Previously this wasn't the case. Outside TCG mode this is not a problem. In TCG mode, we need to be careful and avoid the "prod out of compiled code" step if already in a VCPU thread. This is easily done with a check on current_cpu, i.e. qemu_in_vcpu_thread(). Hopefully, multithreaded TCG will get rid of the whole logic to kick VCPUs whenever an I/O event occurs!

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.

2015-06-23migration: introduce VMSTATE_BUFFER_UNSAFE_INFO_TEST()Laszlo Ersek
There is no _TEST() variant of VMSTATE_BUFFER_UNSAFE_INFO() yet, but we'll soon need it. Introduce it and rebase the original VMSTATE_BUFFER_UNSAFE_INFO() on top. The parameter order of the new function-like macro follows that of VMSTATE_SINGLE_TEST(): "_test" is introduced between "_state" and "_version".

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. It introduces deflate-on-oom option for balloon device which does the trick. Signed-off-by: Denis V.
