2016-10-28ppc/pnv: add a PIR handler to PnvChipCédric Le Goater
The Processor Identification Register (PIR) is a register that holds a processor identifier which is used for bus transactions (XSCOM) and for processor differentiation in multiprocessor systems. It also used in the interrupt vector entries (IVE) to identify the thread serving the interrupts. P9 and P8 have some differences in the CPU PIR encoding.

2016-10-28ppc/pnv: add a PnvChip objectCédric Le Goater
This is is an abstraction of a POWER8 chip which is a set of cores plus other 'units', like the pervasive unit, the interrupt controller, the memory controller, the on-chip microcontroller, etc. The whole can be seen as a socket. It depends on a cpu model and its characteristics: max cores and specific inits are defined in a PnvChipClass. We start with an near empty PnvChip with only a few cpu constants which we will grow in the subsequent patches with the controllers required to run the system. The Chip CFAM (Common FRU Access Module) ID gives the model of the chip and its version number. It is generally the first thing firmwares fetch, available at XSCOM PCB address 0xf000f, to start initialization.

2016-10-28ppc/pnv: add skeleton PowerNV platformBenjamin Herrenschmidt
The goal is to emulate a PowerNV system at the level of the skiboot firmware, which loads the OS and provides some runtime services. Power Systems have a lower firmware (HostBoot) that does low level system initialization, like DRAM training. This is beyond the scope of what qemu will address in a PowerNV guest. No devices yet, not even an interrupt controller. Just to get started, some RAM to load the skiboot firmware, the kernel and initrd. The device tree is fully created in the machine reset op.

When configured to compile out of tree, the configure script copies BIOS blobs to the build directory. However since the PPC64 powernv machine ROM has .lid extension, it is ignored and "make check" fails when trying the powernv machine. This adds *.lid to the list of copied blobs.

2016-10-28pseries: Remove unused callbacks from sPAPR VIO bus stateDavid Gibson
The original QOMification of the spapr VIO devices in 3954d33 "spapr: convert to QEMU Object Model (v2)" moved some callbacks from the VIOsPAPRBus structure to the VIOsPAPRDeviceClass. Except, that it forgot to actually remove them from the VIOsPAPRBus structure (which still exists, though it doesn't fulfill quite the same function as it did pre-QOM).

2016-10-28spapr_pci: advertise explicit numa IDs even when there's 1 nodeMichael Roth
With the addition of "numa_node" properties for PHBs we began advertising NUMA affinity in cases where nb_numa_nodes > 1. Since the default on the guest side is to make no assumptions about PHB NUMA affinity (defaulting to -1), there is still a valid use-case for explicitly defining a PHB's NUMA affinity even when there's just one node. In particular, some workloads make faulty assumptions about /sys/bus/pci/<devid>/numa_node being >= 0, warranting the use of this property as a workaround even if there's just 1 PHB or NUMA node. Enable this use-case by always advertising the PHB's NUMA affinity if "numa_node" has been explicitly set. We could achieve this by relaxing the check to simply be nb_numa_nodes > 0, but even safer would be to check numa_info[nodeid].present explicitly, and to fail at start time for cases where it does not exist. This has an additional affect of no longer advertising PHB NUMA affinity unconditionally if nb_numa_nodes > 1 and "numa_node" property is unset/-1, but since the default value on the guest side for each PHB is also -1, the behavior should be the same for that situation. We could still retain the old behavior if desired, but the decision seems arbitrary, so we take the simpler route. Cc: Alexey Kardashevskiy <aik@ozlabs.ru> Cc: Shivaprasad G.

This makes the FloppyDrive qdev object actually useful: Now that it has all properties that don't belong to the controller, you can actually use '-device floppy' and get a working result. Command line semantics is consistent with CD-ROM drives: By default you get a single empty floppy drive. You can override it with -drive and using the same index, but if you use -drive to add a floppy to a different index, you get both of them. However, as soon as you use any '-device floppy', even to a different slot, the default drive is disabled. Using '-device floppy' without specifying the unit will choose the first free slot on the controller.

2016-10-27block/nbd: Add nbd_has_filename_options_conflict()Max Reitz
Right now, we have four possible options that conflict with specifying an NBD filename, and a future patch will add another one ("address"). This future option is a nested QDict that is flattened at this point, requiring us to test each option whether its key has an "address." prefix. Therefore, we will then need to iterate through all options (including the "export" option which was not covered so far). Adding this iteration logic now will simplify adding the new option later. A nice side effect is that the user will not receive a long list of five options which are not supposed to be specified with a filename, but we can actually print the problematic option.

2016-10-27block/nbd: Reject port parameter without hostMax Reitz
Currently, a port that is passed along with a UNIX socket path is silently ignored. That is not exactly ideal, it should be an error instead.

2016-10-27qemu-iotests: Fix typo for NFS with IMGOPTSSYNTAXKevin Wolf
Commit 076003f5 added configuration for NFS with IMGOPTSSYNTAX enabled, but it didn't use the right variable name: $TEST_DIR_OPTS doesn't exist. This fixes the mistake. However, this doesn't make anything work that was broken before: The only way to get IMGOPTSSYNTAX is with -luks, but the combination of -luks and -nfs doesn't get qemu-img create commands right (because qemu-img create doesn't support --image-opts yet), so even after this fix some more work would be required to make the tests pass.

2016-10-27raw: Implement .bdrv_co_ioctl instead of .bdrv_aio_ioctlKevin Wolf
It's the simpler interface to use for the raw format driver. Apart from that, this removes the last user of the AIO emulation implemented by bdrv_aio_ioctl(). Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
