2010-06-01Monitor: Drop QMP documentation from codeLuiz Capitulino9-368/+0
Previous commit added QMP documentation to the qemu-monitor.hx file, it's is a copy of this information. While it's good to keep it near code, maintaining two copies of the same information is too hard and has little benefit as we don't expect client writers to consult the code to find how to use a QMP command.

2010-06-01QMP: Introduce commands documentationJan Kiszka5-4/+1376
One of the most important missing feature in QMP today is its supported commands documentation. The plan is to make it part of self-description support, however self-description is a big task we have been postponing for a long time now and still don't know when it's going to be done. In order not to compromise QMP adoption and make users' life easier, this commit adds a simple text documentation which fully describes all QMP supported commands. This is not ideal for a number of reasons (harder to maintain, text-only, etc) but does improve the current situation. To avoid at least divering from the user monitor help and texi snippets, QMP bits are also maintained inside qemu-monitor.hx, and hxtool is extended to generate a single text file from them.

2010-06-01migration: Fix calculation of bytes_transferredPierre Riteau1-9/+12
When a page with all identical bytes is transferred, it is counted as a full page (TARGET_PAGE_SIZE) although only one byte is actually sent. Fix this by changing ram_save_block() to return the number of bytes sent instead of a boolean value. This makes bandwidth estimation, and consequently downtime estimation, more precise.

2010-06-01vnc: tight: add palette encodingCorentin Chary1-12/+425
Add palette tight encoding. Palette encoding will try to count the number of colors for a given rectangle, and if this number is low enough (< 256) it will send the palette + the rectangle with indexed colors.

2010-06-01vnc: add basic tight supportCorentin Chary7-4/+498

2010-06-01vnc: return the number of rectanglesCorentin Chary4-16/+26
Some encodings like tight supports tiling (spliting in multiple sub-rectangles). So we needed a way to tell vnc_update_client() how much rectangles are in the buffer. zlib, raw and hextile always send a full rectangle.

2010-06-01vnc: don't clear zlib stream on set_encodingCorentin Chary3-7/+0
On init, values are already NULL, but we shouldn't try to reset them each time a client send a set encoding command because this break everything. For example, libvncclient re-send a set encoding command if the framebuffer is resized. This fix framebuffer resizing for zlib encoding.

2010-06-01vnc: only use a single zlib streamCorentin Chary2-8/+6
According to http://tigervnc.org/cgi-bin/rfbproto#zlib-encoding zlib encoding only uses a single stream. Current implementation defines 4 streams but only uses the first one. Remove them and only use a single stream. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: really call zlib if we want zlibCorentin Chary1-1/+1

2010-06-01vnc: explain why set_encodings loop is reversedCorentin Chary1-0/+5

2010-06-01Revert "vnc: set the right prefered encoding"Corentin Chary1-10/+4
This patch was wrong, because the loop was already reversed, so the first encoding was correctly set at the end of the loopp. This reverts commit 14eb8b6829ad9dee7035de729e083844a425f274. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
