2013-07-15net: add support of mac-programming over macvtap in QEMU sideAmos Kong8-6/+336
Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S.

2013-07-07pci: Fold host_buses list into PCIHostState functionalityDavid Gibson2-19/+16
The host_buses list is an odd structure - a list of pointers to PCI root buses existing in parallel to the normal qdev tree structure. This patch removes it, instead putting the link pointers into the PCIHostState structure, which have a 1:1 relationship to PCIHostBus structures anyway.

2013-07-07pci: Remove domain from PCIHostBusDavid Gibson1-4/+3

2013-07-07pci: Simpler implementation of primary PCI busDavid Gibson2-9/+26
Currently pci_find_primary_bus() searches the list of root buses for one with domain 0. But since host buses are always registered with domain 0, this just amounts to finding the only PCI host bus. The only remaining users of pci_find_primary_bus() are in pci-hotplug-old.c, which implements the old style pci_add/pci_del commands. Therefore, this patch redefines pci_find_primary_bus() to find the only PCI root bus, returning an error if there are multiple roots. The callers in pci-hotplug-old.c are updated correspondingly, to produce sensible error messages. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael S.

2013-07-07pci: Add root bus parameter to pci_nic_init()David Gibson17-26/+36
At present, pci_nic_init() and pci_nic_init_nofail() assume that they will only create a NIC under the primary PCI root. As we add support for multiple PCI roots, that may no longer be the case. This patch adds a root bus parameter to pci_nic_init() (and updates callers accordingly) to allow the machine init code using it to specify the right PCI root for NICs created by old-style -net nic parameters. NICs created new-style, with -device can of course be put anywhere. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-07-07pci: Add root bus argument to pci_get_bus_devfn()David Gibson3-6/+7
pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus * and device/function number within that bus. Currently it assumes it is working on an address under the primary PCI root bus. This patch extends it to allow the caller to specify a root bus. This might seem a little odd since the supplied address can (theoretically) include a PCI domain number. However, attempting to use a non-zero domain number there is currently an error, so that shouldn't really cause problems.

2013-07-07pci: Replace pci_find_domain() with more general pci_root_bus_path()David Gibson9-25/+66
pci_find_domain() is used in a number of places where we want an id for a whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is that many platforms may support multiple independent host bridges with no hardware supplied notion of domain number. This patch, therefore, replaces calls to pci_find_domain() with calls to a new pci_root_bus_path() returning a string. The new call is implemented in terms of a new callback in the host bridge class, so it can be defined in some way that's well defined for the platform. When no callback is available we fall back on the qbus name. Most current uses of pci_find_domain() are for error or informational messages, so the change in identifiers should be harmless. The exception is pci_get_dev_path(), whose results form part of migration streams. To maintain compatibility with old migration streams, the PIIX PCI host is altered to always supply "0000" for this path, which matches the old domain number (since the code didn't actually support domains other than 0). For the pseries (spapr) PCI bridge we use a different platform-unique identifier (pseries machines can routinely have dozens of PCI host bridges). Theoretically that breaks migration streams, but given that we don't yet have migration support for pseries, it doesn't matter. Any other machines that have working migration support including PCI devices will need to be updated to maintain migration stream compatibility.

2013-07-07pci: Use helper to find device's root bus in pci_find_domain()David Gibson4-11/+17
Currently pci_find_domain() performs two functions - it locates the PCI root bus above the given bus, then looks up that root bus's domain number. This patch adds a helper function to perform the first task, finding the root bus for a given PCI device. This is then used in pci_find_domain(). This changes pci_find_domain()'s signature slightly, taking a PCIDevice instead of a PCIBus - since all callers passed something of the form dev->bus, this simplifies things slightly.

2013-07-07pci: Abolish pci_find_root_bus()David Gibson4-15/+42
pci_find_root_bus() takes a domain parameter. Currently PCI root buses with domain other than 0 can't be created, so this is more or less a long winded way of retrieving the main PCI root bus. Numbered domains don't actually properly cover the (non x86) possibilities for multiple PCI root buses, so this patch for now enforces the domain == 0 restriction in other places to replace pci_find_root_bus() with an explicit pci_find_primary_bus().

2013-07-04pci: Cleanup configuration for pci-hotplug.cDavid Gibson6-12/+8
pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its compilation are misnamed. They're not about PCI hotplug in general, but rather about the pci_add/pci_del interface which are now deprecated in favour of the more general device_add/device_del interface. This patch therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD. CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no particular reason, so we clean that up too. In addition it was included in ppc64-softmmu.mak for which the old hotplug interface was never used and is unsuitable, so we remove that too. Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386. The small piece which wasn't is only called from the pci_add and pci_del hooks in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386. This patch therefore also removes the #ifdef from pci-hotplug-old.c, and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

Avoid use of static variables: PC systems initialize pvpanic device through pvpanic_init, so we can simply create the fw_cfg file at that point. This also makes it possible to skip device creation completely if fw_cfg is not there, e.g. for xen - so the ports it reserves are not discoverable by guests. Also, make pvpanic_init void since callers ignore return status anyway.

Coverity complains about two overruns in process_tx_desc(). The complaints are false positives, but we might as well eliminate them. The problem is that "hdr" is defined as an unsigned int, but then used to offset an array of size 65536, and another of size 256 bytes. hdr will actually never be greater than 255 though, as it's assigned only once and to the value of tp->hdr_len, which is an uint8_t.

2013-07-01PPC: Ignore writes to L2CRAlexander Graf1-11/+11
The L2CR register contains a number of bits that either impose configuration which we can't deal with or mean "something is in progress until the bit is 0 again".

This patch adds a memory alias region that takes normal escc registers and maps them into the escc-legacy register space. With this patch applied, a Mac OS X guest successfully emits debug output on the serial port when run with debug parameters set, for example by running: $ qemu-system-ppc -prom-env -'boot-args=-v debug=0x8 io=0xff serial=0x3' \ -cdrom 10.4.iso -boot d Signed-off-by: Alexander Graf <agraf@suse.de>

2013-07-01spapr-rtas: add CPU argument to RTAS callsAnthony Liguori8-28/+37
RTAS is a hypervisor provided binary blob that a guest loads and calls into to execute certain functions. It's similar to the vsyscall page in Linux or the short lived VMCI paravirt interface from VMware. The QEMU implementation of the RTAS blob is simply a passthrough that proxies all RTAS calls to the hypervisor via an hypercall. While we pass a CPU argument for hypercall handling in QEMU, we don't pass it for RTAS calls. Since some RTAs calls require making hypercalls (normally RTAS is implemented as guest code) we have nasty hacks to allow that. Add a CPU argument to RTAS call handling so we can more easily invoke hypercalls just as guest code would.
