Leon3 is an open-source VHDL System-On-Chip, well known in space industry (more
information on http://www.gaisler.com).
Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

This patch replaces explicit bswaps with endianness hints to the

Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.

The e1000 has compatibility code to handle big endianness which makes it
mandatory to be recompiled on different targets.
With the generic mmio endianness solution, there's no need for that anymore.
We just declare all mmio to be little endian and call it a day.

move the driver over to Makefile.objs.

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".

[ v2: use qemu-common.h for standard includes ]
[ v2: create separate qxl-vga device for primary ]

This introduces generation of a qemu.stp/qemu-system-XXX.stp
files which provides tapsets with friendly names for static
probes & their arguments. Instead of
probe process("qemu").mark("qemu_malloc") {
printf("Malloc %d %p\n", $arg1, $arg2);
}
It is now possible todo
probe qemu.system.i386.qemu_malloc {
printf("Malloc %d %p\n", size, ptr);
}
There is one tapset defined per target arch, for both
user and system emulators.
* Makefile.target: Generate stp files for each target
* tracetool: Support for generating systemtap tapsets
* configure: Check for whether systemtap is available

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.

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.

Introduce a new encoding: VNC_ENCODING_TIGHT_PNG [1] (-269) with a new
tight filter VNC_TIGHT_PNG (0x0A). When the client tells it supports the Tight PNG
encoding, the server will use tight, but will always send encoding pixels using
PNG instead of zlib. If the client also told it support JPEG, then the server can
send JPEG, because PNG will only be used in the cases zlib was used in normal tight.
This encoding was introduced to speed up HTML5 based VNC clients like noVNC [2], but
can also be used on devices like iPhone where PNG can be rendered in hardware.

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.
