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.

We have stayed at 800x600x15 as default graphics mode for the last 9 years. If there ever was a reason to be there, surely nobody remembers it. However, recently non-Linux PPC guests started to show bad effects on 15 bit color mode. They do work just fine with 32 bits however. So let's switch to 32 bit color as the default graphic mode.

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.

Currently, for qemu-system-ppc64, the default machine type is 'mac99'. The mac99 machine is not being actively maintained, and represents a bizarre hybrid of components that never actually existed as a real system.

Enables support for the in-kernel MPIC that thas been merged into the KVM next branch. This includes irqfd/KVM_IRQ_LINE support from Alex Graf (along with some other improvements). Note from Alex regarding kvm_irqchip_create(): On x86, one would call kvm_irqchip_create() to initialize an in-kernel interrupt controller. That function then goes ahead and initializes global capability variables as well as the default irq routing table. On ppc, we can't call kvm_irqchip_create() because we can have different types of interrupt controllers. So we want to do all the things that function would do for us in the in-kernel device init handler.

The current logic updates KVM's view of our interrupt map every time we change it. While this is nice and bullet proof, it slows things down badly for me. QEMU spends about 3 seconds on every start telling KVM what news it has on its routing maps. Instead, let's just synchronize the whole irq routing map as a whole when we're done constructing it. For things that change during runtime, we can still update the routing table on demand. Signed-off-by: NAlexander Graf <agraf@suse.de>

The usual MSI injection mechanism writes msi.data into memory using an le32 wrapper. So on big endian guests, this swaps msg.data into the expected byte order.

On PPC, we don't support MP state. So far it's not necessary and I'm not convinced yet that we really need to support it ever. However, the current idle logic in QEMU assumes that an in-kernel PIC also means we support MP state. This assumption is not true anymore. Let's split up the two cases into two different variables. That way PPC can expose an in-kernel PIC, while not implementing MP state. Signed-off-by: NAlexander Graf <agraf@suse.de> CC: Jan Kiszka <jan.kiszka@siemens.com>
