      trace: Add trace-events file for declaring trace events · 94a420b1
      由 Stefan Hajnoczi 提交于 
      This patch introduces the trace-events file where trace events can be
declared like so:

qemu_malloc(size_t size) "size %zu"
qemu_free(void *ptr) "ptr %p"

These trace event declarations are processed by a new tool called
tracetool to generate code for the trace events.  Trace event
declarations are independent of the backend tracing system (LTTng User
Space Tracing, ftrace markers, DTrace).

The default "nop" backend generates empty trace event functions.
Therefore trace events are disabled by default.

The trace-events file serves two purposes:

1. Adding trace events is easy.  It is not necessary to understand the
   details of a backend tracing system.  The trace-events file is a
   single location where trace events can be declared without code
   duplication.

2. QEMU is not tightly coupled to one particular backend tracing system.
   In order to support tracing across QEMU host platforms and to
   anticipate new backend tracing systems that are currently maturing,
   it is important to be flexible and not tied to one system.

      RESEND: Inter-VM shared memory PCI device · 6cbf4c8c
      由 Cam Macdonell 提交于 
      resend for bug fix related to removal of irqfd

Support an inter-vm shared memory device that maps a shared-memory object as a
PCI device in the guest.  This patch also supports interrupts between guest by
communicating over a unix domain socket.  This patch applies to the qemu-kvm
repository.

    -device ivshmem,size=<size in format accepted by -m>[,shm=<shm name>]

Interrupts are supported between multiple VMs by using a shared memory server
by using a chardev socket.

    -device ivshmem,size=<size in format accepted by -m>[,shm=<shm name>]
           [,chardev=<id>][,msi=on][,ioeventfd=on][,vectors=n][,role=peer|master]
    -chardev socket,path=<path>,id=<id>

The shared memory server, sample programs and init scripts are in a git repo here:

      AppleSMC device emulation · 1ddda5cd
      由 Alexander Graf 提交于 
      Intel Macs have a chip called the "AppleSMC" which they use to control
certain Apple specific parts of the hardware, like the keyboard background
light.

That chip is also used to store a key that Mac OS X uses to decrypt binaries.

This patch adds emulation for that chip, so we're getting one step further
to having Mac OS X run natively on Qemu.
