Andreas Färber 91f169004d trace: Fix user emulator dependency on trace objects
On a clean build, after generating trace.h, make would recurse into *-*-user
without a clue how to build ../trace.o (added to $(obj-y) in Makefile.target)
since its generation rule is in the main Makefile.
The softmmus are seemingly unaffected because the $(TOOLS), which each have
a dependency on $(trace-obj-y), are built first for the build-all target.

Add a dependency on $(trace-obj-y) for %-user, as done for the qemu-* tools.

Let's be paranoid and do the same for %-softmmu while at it, just in case
someone messes with $(TOOLS) or calls the Makefile target directly.

Gerd Hoffmann 869564a9c0 spice: add tablet support
Add support for the spice tablet interface.  The tablet interface will
be registered (and then used by the spice client) as soon as a absolute
pointing device is available and used by the guest, i.e. you'll have to
configure your guest with '-usbdevice tablet'.

Gerd Hoffmann a3e2226031 spice: simple display
With that patch applied you'll actually see the guests screen in the
spice client.  This does *not* bring qxl and full spice support though.
This is basically the qxl vga mode made more generic, so it plays
together with any qemu-emulated gfx card.  You can display stdvga or
cirrus via spice client.  You can have both vnc and spice enabled and
clients connected at the same time.

Gerd Hoffmann 78dd9ac1ca spice: add mouse
Open mouse channel.  Now you can move the guests mouse pointer.
No tablet / absolute positioning (yet) though.
2010-09-21 18:36:42 +02:00
Gerd Hoffmann 864401c2a7 spice: add keyboard
Open keyboard channel.  Now you can type into the spice client and the
keyboard events are sent to your guest.  You'll need some other display
like vnc to actually see the guest responding to them though.

Gerd Hoffmann 29b0040be6 spice: core bits
Add -spice command line switch.  Has support setting passwd and port for

to qemu.  You can't do anything useful yet though.

displays (for now only vnc, spice will follow) can be enabled
independently.

Stefan Hajnoczi d9d334176c blkverify: Add block driver for verifying I/O
The blkverify block driver makes investigating image format data
corruption much easier.  A raw image initialized with the same contents
as the test image (e.g. qcow2 file) must be provided.  The raw image
mirrors read/write operations and is used to verify that data read from
the test image is correct.

See docs/blkverify.txt for more information.

Kevin Wolf 6f5f060b73 qcow2: Avoid bounce buffers for AIO write requests
qcow2 used to use bounce buffers for any AIO requests. This does not only imply
unnecessary copying, but also unbounded allocations which should be avoided.

This patch removes bounce buffers from the normal AIO write path. Encrypted
images continue to use a bounce buffer, however with constant size.

Christoph Hellwig 1b2adf2803 ide: propagate the required alignment
IDE is a bit ugly in this respect.  For one it doesn't really keep track
of a sector size - most of the protocol is in units of 512 bytes, and we
assume 2048 bytes for CDROMs which is correct most of the time.

Second IDE allocates an I/O buffer long before we know if we're dealing
with a CDROM or not, so increase the alignment for the io_buffer
unconditionally.
