Let's introduce a general "inject_nmi()" function that doesn't rely on the cpu index of the monitor, but uses cpu index 0 as default (except for x86). This function can then later be used from a non-monitor context.

2015-06-05target-i386: use memory API to implement SMRAMPaolo Bonzini
Remove cpu_smm_register and cpu_smm_update. Instead, each CPU address space gets an extra region which is an alias of /machine/smram. This extra region is enabled or disabled as the CPU enters/exits SMM. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-06-05hw/i386: add a separate region that tracks the SMRAME bitPaolo Bonzini
This region is exported at /machine/smram. It is "empty" if SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will enable/disable it as it enters or exits SMRAM. While touching nearby code, the existing memory region setup was slightly inconsistent. The smram_region is *disabled* in order to open SMRAM (because the smram_region shows the low VRAM instead of the RAM at 0xa0000). Because SMRAM is closed at startup, the smram_region must be enabled when creating the i440fx or q35 devices. Acked-by: Michael S.

2015-06-04macio: switch pmac_dma_write() over to new offset/len implementationMark Cave-Ayland
In particular, this fixes a bug whereby chains of overlapping head/tail chains would incorrectly write over each other's remainder cache. This is the access pattern used by OS X/Darwin and fixes an issue with a corrupt Darwin installation in my local tests. While we are here, rename the DBDMA_io struct property remainder to head_remainder for clarification.

2015-06-04vhost: logs sharingJason Wang
Currently we allocate one vhost log per vhost device. This is sub optimal when: - Guest has several device with vhost as backend - Guest has multiqueue devices In the above cases, we can avoid the memory allocation by sharing a single vhost log among all the vhost devices. This is done through: - Introducing a new vhost_log structure with refcnt inside. - Using a global pointer to vhost_log structure that will be used. And introduce helper to get the log with expected log size and helper to - drop the refcnt to the old log. - Each vhost device still keep track of a pointer to the log that was used. With above, if no resize happens, all vhost device will share a single vhost log. During resize, a new vhost_log structure will be allocated and made for the global pointer. And each vhost devices will drop the refcnt to the old log. Tested by doing scp during migration for a 2 queues virtio-net-pci. Cc: Michael S.

2015-06-04hw/acpi: piix4_pm_init(): take fw_cfg object no moreLaszlo Ersek
This PIIX4 init function has no more reason to receive a pointer to the FwCfg object. Remove the parameter from the prototype, and update callers. As a result, the pc_init1() function no longer needs to save the return value of pc_memory_init() and xen_load_linux(), which makes it more similar to pc_q35_init(). The return type & value of pc_memory_init() and xen_load_linux() are not changed themselves; maybe we'll need their return values sometime later.
