This enables qemu -cpu help to return a list of supported CPU models on s390 and also to query for cpu definitions in the monitor. Initially only cpu model = host is returned. This needs to be reworked into a full-fledged CPU model handling later on. This change is needed to allow libvirt exploiters (like OpenStack) to specify a CPU model.

2013-01-18openpic: export e500 epr enable into a ppc.c functionAlexander Graf
Enabling and disabling the EPR capability (mpic_proxy) is a system wide operation. As such, it belongs into the ppc.c file, since that's where PPC specific machine wide logic happens. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-18PPC: e500: Change in-memory order of load blobsAlexander Graf
Today, we load <kernel> <initrd> <dtb> into memory in that order. However, Linux has a bug where it can only handle the dtb if it's within the first 64MB of where <kernel> starts. So instead, let's change the order to <kernel> <dtb> <initrd> making Linux happy. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-18PPC: E500: Calculate loading blob offsets properlyAlexander Graf
We have 3 blobs we need to load when booting the system: - kernel - initrd - dtb We place them in physical memory in that order. At least we should.

2013-01-18openpic: unify gcr mode mask updatesAlexander Graf

2013-01-18dataplane: support viostor virtio-pci status bit settingStefan Hajnoczi
The viostor virtio-blk driver for Windows does not use the VIRTIO_CONFIG_S_DRIVER bit. It only sets the VIRTIO_CONFIG_S_DRIVER_OK bit. The viostor driver refreshes the virtio-pci status byte sometimes while the guest is running. We misinterpret 0x4 (VIRTIO_CONFIG_S_DRIVER_OK) as an indication that virtio-blk-data-plane should be stopped since 0x2 (VIRTIO_CONFIG_S_DRIVER) is missing. The result is that the device becomes unresponsive. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-01-18dataplane: avoid reentrancy during virtio_blk_data_plane_stop()Stefan Hajnoczi
When dataplane is stopping, the s->vdev->binding->set_host_notifier(..., false) call can invoke the virtqueue handler if an ioeventfd notification is pending. This causes hw/virtio-blk.c to invoke virtio_blk_data_plane_start() before virtio_blk_data_plane_stop() returns! The result is that we try to restart dataplane while trying to stop it and the following assertion is raised: msix_set_mask_notifier: Assertion `!dev->msix_mask_notifier' failed. Although the code was intended to prevent this scenario, the s->started boolean isn't enough. Add s->stopping so that we can postpone clearing s->started until we've completely stopped dataplane. This way, virtqueue handler calls during virtio_blk_data_plane_stop() are ignored. When dataplane is legitimately started again later we already self-kick ourselves to resume processing.

2013-01-16tmp105: Fix I2C protocol bugAndreas Färber
An early length postincrement in the TMP105's I2C TX path led to transfers of more than one byte to place the second byte in the third byte's place within the buffer and the third byte to get discarded. Fix this by explictly incrementing the length after the checks but before the callback is called, which again checks the length. Adjust the Coding Style while at it.

2013-01-15pseries: set no default boot orderAvik Sil
This patch removes the default boot order for pseries machine. This allows the machine to handle a NULL boot order in case no -boot option is provided.

This patch makes default boot order machine specific instead of set globally. The default boot order can be set per machine in QEMUMachine boot_order. This also allows a machine to receive a NULL boot order when -boot isn't used and take an appropriate action accordingly.
