2012-08-15Add one new file vga-pci.h and cleanup on all platformszhlcindy@gmail.com
Functions pci_vga_init() and pci_cirrus_vga_init() are declared in pc.h. That prevents other platforms (e.g. sPAPR) to use them. This patch is to create one new file vga-pci.h and move the declarations to vga-pci.h, so that they can be shared by all platforms. This patch also cleans up on all platforms.

2012-08-15Revert "PPC: e500: Use new MPIC dt format"Alexander Graf
This reverts commit 518c7fb44f2182cde943dc64f88cb2fd4e4ff6b5. It breaks new Linux guests with SMP, because IPIs get mapped to large vectors which our MPIC emulation does not implement. Conflicts: hw/ppc/e500.c
2012-08-15ppc: Fix bug in handling of PAPR hypercall exitsDavid Gibson
Currently for powerpc, kvm_arch_handle_exit() always returns 1, meaning that its caller - kvm_cpu_exec() - will always exit immediately afterwards to the loop in qemu_kvm_cpu_thread_fn(). There's no need to do this. Once we've handled the hypercall there's no reason we can't go straight around and KVM_RUN again, which is what ret = 0 will signal. The only exception might be for hypercalls which affect the state of cpu_can_run(), however the only one that might do this is H_CEDE and for kvm that is always handled in the kernel, not qemu. Furtherm setting ret = 0 means that when exit_requested is set from a hypercall, we will enter KVM_RUN once more with a signal which lets the the kernel do its internal logic to complete the hypercall with out actually executing any more guest code. This is important if our hypercall also triggered a reset, which previously would re-initialize everything without completing the hypercall. This caused the kernel to get confused because it thought the guest was still in the middle of a hypercall when it has actually been reset. This patch therefore changes to ret = 0, which is both a bugfix and a small optimization. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-08-15PPC: e500: add generic e500 platformScott Wood
This gives the kernel a paravirtualized machine to target, without requiring both sides to pretend to be targeting a specific board that likely has little to do with the host in KVM scenarios. This avoids the need to add new boards to QEMU, just to be able to run KVM on new CPUs.

Roll the code used to initialize the guest memory space when -R or -B is used into 'init_guest_space' and then call 'init_guest_space' from the driver. This way the reserved guest memory space can be probed for. Calling 'mmap' just once as is currently done is not guaranteed to succeed since the host address space validation might fail.

2012-08-13qmp: add SUSPEND_DISK eventLuiz Capitulino
Emitted when the guest makes a request to enter S4 state. There are three possible ways of having this event, as described here: http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html I've decided to add a new event and make it indepedent of SHUTDOWN. This means that the SHUTDOWN event will eventually follow the SUSPEND_DISK event. I've choosen this way because of two reasons: 1. Having an indepedent event makes it possible to query for its existence by using query-events 2. In the future, we may allow the user to change what QEMU should do as a result of the guest entering S4. So it's a good idea to keep both events separated Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2012-08-13qmp: emit the WAKEUP event when the guest is put to runLuiz Capitulino
Today, the WAKEUP event is emitted when a wakeup _request_ is made. This could be the system_wakeup command, for example. A better semantic would be to emit the event when the guest is already running, as that's what matters in the end. This commit does that change. In theory, this could break compatibility. In practice, it shouldn't happen though, as clients shouldn't rely on timing characteristics of the events. That is, a client relying that the guest is not running when the event arrives may break if the event arrives after the guest is already running. This commit also adds the missing documentation for the WAKEUP event. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2012-08-13qmp: don't emit the RESET event on wakeup from S3Luiz Capitulino
QEMU is basically using reset logic when waking up from S3. This causes the QMP RESET event to be emitted, which is wrong. Also, the runstate checks done in reset are not necessary for S3 wakeup. Fix this by untangling wakeup from reset logic and passing VMRESET_SILENT to qemu_system_reset() to avoid emitting the RESET event.
