'extern' qualifier is useless for function declarations. Delete them. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-12-09vnc/spice: add set_passwd monitor command.Gerd Hoffmann
This patch adds new set_password and expire_password monitor commands which allows to change and expire the password for spice and vnc connections. See the doc update patch chunk for details. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09vnc: support password expireGerd Hoffmann
This patch adds support for expiring passwords to vnc. It adds a new vnc_display_pw_expire() function which specifies the time when the password will expire. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09vnc: auth reject cleanupGerd Hoffmann
protocol_client_auth_vnc() has two places where the auth can fail, with identical code sending the reject message to the client. Move the common code to the end of the function and make both error paths jump there. No functional change. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09spice: add qmp 'query-spice' and hmp 'info spice' commands.Gerd Hoffmann
The patch adds a 'query-spice' monitor command which returns informations about the spice server configuration and also a list of channel connections. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09spice: connection events.Gerd Hoffmann
This patch adds support for connection events to spice. The events are quite simliar to the vnc events. Unlike vnc spice uses multiple tcp channels though. qemu will report every single tcp connection (aka spice channel). If you want track spice sessions only you can filter for the main channel (channel-type == 1). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09spice: add qxl deviceGerd Hoffmann
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: add copyright to files ] [ v2: use qemu-common.h for standard includes ] [ v2: create separate qxl-vga device for primary ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-11-09spice: add audioGerd Hoffmann
Add support for the spice audio interface. With this patch applied audio can be forwarded over the network from/to the spice client. Both recording and playback is supported. The driver is first in the driver list, but the can_be_default flag is set only in case spice is active. So if you have the spice protocol enabled the spice audio driver is the default one, otherwise whatever comes first after spice in the list. Overriding the default using QEMU_AUDIO_DRV works in any case. [ v2: audio codestyle: add spaces before open parenthesis ] [ v2: add const to silence array ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Cc: malc <av1474@comtv.ru> Signed-off-by: malc <av1474@comtv.ru>
2010-11-02spice-display: replace private lock with qemu mutex.Gerd Hoffmann
qemu_spice_create_update() must aquire the global qemu mutex to make sure DisplayState doesn't change while we are accessing it. Once this is in place the private lock is pretty pointless as everything it protects is covered by the global qemu mutex now. Drop it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-10-08spice: add misc config optionsGerd Hoffmann
This patch adds a few more options to tweak spice server behavior. The documentation update chunk has the details ;)
2010-10-08spice: add config options for the listening addressGerd Hoffmann
Make listening address configurable. Also add options to force using IPv4 or IPv6.
2010-10-08spice: add config options for channel security.Gerd Hoffmann
This allows to enforce tls or plaintext usage for certain spice channels. [ v2: code style fixup ]

2010-09-21spice: add tablet supportGerd Hoffmann
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'.
2010-09-21spice: simple displayGerd Hoffmann
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.
2010-09-21spice: add mouseGerd Hoffmann
Open mouse channel. Now you can move the guests mouse pointer. No tablet / absolute positioning (yet) though.
2010-09-21spice: add keyboardGerd Hoffmann
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.
2010-09-21spice: core bitsGerd Hoffmann
Add -spice command line switch. Has support setting passwd and port for now. With this patch applied the spice client can successfully connect to qemu. You can't do anything useful yet though.

2010-08-15win32: Avoid compiler warning (WIN32_LEAN_AND_MEAN redefined)Stefan Weil
configure adds the macro WIN32_LEAN_AND_MEAN to QEMU_CFLAGS, and SDL_syswm.h defines it, too. This results in a compiler warning (redefinition of WIN32_LEAN_AND_MEAN in SDL_syswm.h. That warning prevents compilations for win32 with warning = error). Fix this by removing the definition of WIN32_LEAN_AND_MEAN before including SDL_syswm.h.

2010-07-26vnc: threaded VNC serverCorentin Chary
Implement a threaded VNC server using the producer-consumer model. The main thread will push encoding jobs (a list a rectangles to update) in a queue, and the VNC worker thread will consume that queue and send framebuffer updates to the output buffer. The threaded VNC server can be enabled with ./configure --enable-vnc-thread. If you don't want it, just use ./configure --disable-vnc-thread and a syncrhonous queue of job will be used (which as exactly the same behavior as the old queue). If you disable the VNC thread, all thread related code will not be built and there will be no overhead.

2010-07-26vnc: tight: stop using qdict for palette stuffCorentin Chary
Profiling with callgrind seems to show that a lot of time is spent in the palette code (mostly due to memory allocation and qdict to int conversion). This patch adds a VncPalette implementation. The palette is stored in a hash table, like qdict, but which does way less memory allocations, and doesn't suffer from the QObject overhead.

2010-07-26vnc: tight: specific zlib level and filters for each compression levelCorentin Chary
Disable png filters for lower compression levels. This should lower the CPU consumption and reduce encoding time. This isn't in tight_conf because: * tight_conf structure must not change, because it's shared with other tight implementations (libvncserver, etc..). * it'd exceed the 80 col limit. * PNG_ macros are only defined if CONFIG_VNC_PNG is defined Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: tight add PNG encodingCorentin Chary
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.
