2009-02-16Support multiple VNC clients (Brian Kress)aliguori
Change structure associated with a display from VncState to a new structure VncDisplay. Remove client specific fields from VncDisplay. Remove display specific fields from VncState. Maintain a linked list of VncStates per VncDisplay structure, update as necessary. When updates/resizes/copies come in from the hardware, dispatch to all clients.

2009-02-02Add zlib encoding support (Alexander Graf)aliguori
This patch adds zlib encoding support for VNC. It basically runs the raw traffic through zlib, providing a pretty good compression ratio.

2009-02-02Move the framebuffer update package out (Alexander Graf)aliguori
Currently the send_framebuffer_update_raw and send_framebuffer_update_hextile respectively send a send_framebuffer_update packet themselves.

2009-02-02Add some tight awareness to vnc.c (Alexander Graf)aliguori
This patch enables the vnc server to understand fundamental tight extensions. It changes from a "Hextile or not" scheme when sending framebuffer updates to a "preferred encoding", namely the last one set. While this is not perfect, as actually a list of "preferred encodings" should be kept, it's good enough for now.

2009-02-02Use VNC protocol defines (Alexander Graf)aliguori
Now that we have nice defines for all sorts of constants, let's use them! This patch also takes the "feature variables", currently called has_* into a single feature int. This way adding new features is a lot easier and doesn't clutter the VncState struct.

2009-02-02Split VNC defines to vnc.h (Alexander Graf)aliguori
The VNC protocol contains quite some constants, some of which are currently hardcoded in the vnc.c code. This is not exactly pretty. Let's move all those constants out to vnc.h, so they are clearly separated. While at it, I also included other defines that will be used later in this patch series.

2009-01-26vnc fixes and improvements (Stefano Stabellini)aliguori
this patch fixes a bug and improves the generic pixel conversion function in vnc.c. The bug is that when a new vnc client connects we need to reset the flag has_WMVi but currently we don't. The generic pixel conversion function is vnc_convert_pixel and currently is not very efficient since uses the division and multiplication operators. To make it more efficient I changed to use bit shift operators instead.

2009-01-15DisplayState interface change (Stefano Stabellini)aliguori
This patch changes the DisplayState interface adding support for multiple frontends at the same time (sdl and vnc) and implements most of the benefit of the shared_buf patch without the added complexity. Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is also responsible for allocating the data and setting the depth. Vga.c (or another backend) will do any necessary conversion. The idea is to change it so that is vga.c (or another backend) together with console.c that fully manage the DisplayState interface allocating data and setting the depth (either 16 or 32 bit, if the guest uses a different resolution or is in text mode, vga.c (or another backend) is in charge of doing the conversion seamlessly). The other idea is that DisplayState supports *multiple* frontends like sdl and vnc; each of them can register some callbacks to be called when a display event occurs. The interesting changes are: - the new structures and related functions in console.h and console.c in particular the following functions are very helpful to manage a DisplaySurface: qemu_create_displaysurface qemu_resize_displaysurface qemu_create_displaysurface_from qemu_free_displaysurface - console_select and qemu_console_resize in console.c this two functions manage multiple consoles on a single host display - moving code around in hw/vga.c as for the shared_buf patch this is necessary to be able to handle a dynamic DisplaySurface bpp - changes to vga_draw_graphic in hw/vga.c this is the place where the DisplaySurface buffer is shared with the videoram, when possible; Compared to the last version the only changes are: - do not remove support to dpy_copy in cirrus_vga - change the name of the displaysurface handling functions Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6336 c046a42c-6fe2-441c-8c8c-71466251a162

When using an existing unix socket like: -vnc unix:/tmp/file1Y2nY2 qemu fails to bind a unix socket because the vnc call to unix_listen includes the unix: prefix and stores that in the unix.sun_path.

2008-11-11sockets: switch vnc to new code, support vnc port auto-allocation (Gerd Hoffman)aliguori
This patch switches the vnc code ofer to the new socket helper functions. It adds support IPv6 support and for automatically allocating an unused vnc display port. The latter is handled ising a to= option, specifying the upper limit for the display number to try. Scanning is started at the display number given in the display specification, i.e. this command line: -vnc localhost:7,to=11 will try displays 7 to 11 (inclusive). There are also new "ipv4" and "ipv6" options to make qemu try only the specified internet protocol version. The display actually allocated can be queried using the "info vnc" monitor command.
