Rather than assert, simply return PCI_INTX_DISABLED when we don't have a pci_route_irq_fn. PIIX already returns DISABLED for an invalid pin, so users already deal with this state. Users of this interface should only be acting on an ENABLED or INVERTED return value (though we really have no support for INVERTED). Also complain loudly when we hit this so we don't forget it's missing. Signed-off-by: NAlex Williamson <alex.williamson@redhat.com> Signed-off-by: NMichael S.

At present, using 'system_powerdown' from the monitor or otherwise instructing qemu to (cleanly) shut down a pseries guest will not work, because we did not have a method of signalling the shutdown request to the guest. PAPR does include a usable mechanism for this, though it is rather more involved than the equivalent on x86. This involves sending an EPOW (Environmental and POwer Warning) event through the PAPR event and error logging mechanism, which also has a number of other functions. This patch implements just enough of the event/error logging functionality to be able to send a shutdown event to the guest. At least with modern guest kernels and a userspace that is up and running, this means that system_powerdown from the qemu monitor should now work correctly on pseries guests.

With PAPR guests, hypercalls allow registration of the Virtual Processor Area (VPA), SLB shadow and dispatch trace log (DTL), each of which allow for certain communication between the guest and hypervisor. Currently, we store the addresses of the three areas and the size of the dtl in CPUPPCState. The SLB shadow and DTL are variable sized, with the size being retrieved from within the registered memory area at the hypercall time. This size can later be overwritten with other information, however, so we need to save the size as of registration time. We already do this for the DTL, but not for the SLB shadow, so this patch fixes that. In addition, we change the storage of the VPA information to use fixed size integer types which will make life easier for syncing this data with KVM, which we will need in future.

Currently the pseries machine code allows a callback to be registered for a hypercall number twice, as long as it's the same callback the second time. We don't test for duplicate registrations of RTAS callbacks at all so it will effectively be last registratiojn wins. This was originally done because it was awkward to ensure that the registration happened exactly once, but the code has since been restructured so that's no longer the case. Duplicate registration of a hypercall or RTAS call could well suggest a duplicate initialization which could cause other problems, so this patch makes duplicate registrations a bug, to prevent the old behaviour from hiding other bugs.

When -usb option is used, global varible usb_enabled is set. And all the plaform will create one USB controller according to this variable. In fact, global varibles make code hard to read. So this patch is to remove global variable usb_enabled and add USB option in machine options. All the plaforms will get USB option value from machine options. USB option of machine options will be set either by: * -usb * -machine type=pseries,usb=on Both these ways can work now. They both set USB option in machine options. In the future, the first way will be removed. Signed-off-by: NLi Zhang <zhlcindy@linux.vnet.ibm.com> Acked-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAlexander Graf <agraf@suse.de>

For all our PPC targets the physical address space is at least 36 bits, so drop an unnecessary preprocessor conditional check on TARGET_PHYS_ADDR_SPACE_BITS (erroneously introduced as part of the change from target_phys_addr_t to hwaddr). This brings this bit of code into line with the way we handle the other cases which were originally checking TARGET_PHYS_ADDR_BITS in order to avoid compiler complaints about overflowing a 32 bit type.

When we allocate a reserved_va for the guest, the kernel will likely choose an address well above 4G. At which point we must use a pair of movabsq+addq to form the host address.

With normal FP, this doesn't have much affect on the generated code, because most of the FP operations are not CONST/PURE, and so we spill registers in about the same frequency as the explicit load/stores. But with Loongson multimedia instructions, which are all integral and whose helpers are in fact CONST+PURE, this greatly improves the code.
