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().

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. This patch simply gets rid of hdr, replacing it with tp->hdr_len, which makes it consistent with all other tp member use in the function. v2: - also cleanup coding style issues in the touched lines Signed-off-by: NAndrew Jones <drjones@redhat.com> Signed-off-by: NMichael S.

Sometimes we need to pass ranges around, add a handy structure for this purpose. Note: memory.c defines its own concept of AddrRange structure for working with 128 addresses. It's necessary there for doing range math. This is not needed for most users: struct Range is much simpler, and is only used for passing the range around.

kvmclock should not count while vm is paused, because: 1) if the vm is paused for long periods, timekeeping math can overflow while converting the (large) clocksource delta to nanoseconds. 2) Users rely on CLOCK_MONOTONIC to count run time, that is, time which OS has been in a runnable state (see CLOCK_BOOTTIME). Change kvmclock driver so as to save clock value when vm transitions from runnable to stopped state, and to restore clock value from stopped to runnable transition.

kvm_add_routing_entry makes an attempt to zero-initialize any new routing entry. However, it fails to initialize padding within the u field of the structure kvm_irq_routing_entry. Other functions like kvm_irqchip_update_msi_route also fail to initialize the padding field in kvm_irq_routing_entry. It's better to just make sure all input is initialized. Once it is, we can also drop complex field by field assignment and just do the simple *a = *b to update a route entry. Signed-off-by: NMichael S.

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". Since we don't model the former and we do want to accomodate guests using the latter semantics, let's just ignore writes to L2CR. That way guests always read back 0 and are usually happy with that.

Mac OS X's debugging serial driver accesses the ESCC through a different register layout, called "escc-legacy". This layout differs from the normal escc register layout purely by the location of the respective registers. 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: NAlexander Graf <agraf@suse.de>

When running QEMU with "-cpu ?" we walk through every alias for every target CPU we know about. This takes several seconds on my very fast host system. Let's introduce a class object cache in the alias table. Using that we don't have to go through the tedious work of finding our target class. Instead, we can just go directly from the alias name to the target class pointer. This patch brings -cpu "?" to reasonable times again.

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.
