2010-10-11vnc: check fd before calling qemu_set_fd_handler2() in vnc_client_write()Yoshiaki Tamura1-1/+1
Setting fd = -1 to qemu_set_fd_handler2() causes bus error at FD_SET in main_loop_wait(). Signed-off-by: Yoshiaki Tamura <tamura.yoshiaki@lab.ntt.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit ac71103dc6b408775ae72067790ab367912f75ec)
2010-07-26vnc: tight: split send_sub_rectCorentin Chary1-25/+55
Split send_sub_rect in send_sub_rect_jpeg and send_sub_rect_nojpeg to remove all these #ifdef CONFIG_JPEG. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: tight: fix rgb_prepare_rowCorentin Chary1-5/+10
rgb_prepare_row bpp depends on the server display surface, not the client. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: add missing lock for vnc_cursor_define()Corentin Chary1-0/+2
All vnc_write() calls must be locked (except the ones present before the protocol initialization). Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: threaded VNC serverCorentin Chary5-25/+663
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: fix tight png memory leakCorentin Chary1-0/+3
The tight.png buffer was never released. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: encapsulate encoding membersCorentin Chary5-156/+163
This will allow to implement the threaded VNC server in a more cleaner way. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: tight: stop using qdict for palette stuffCorentin Chary3-128/+234
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 Chary1-1/+18
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 Chary4-54/+304
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.

2010-07-26vnc: tight: don't forget do at the last colorCorentin Chary1-1/+1
While using indexed colors, the last color was never added to the palette. Triggered with ubuntu livecd. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: rename vnc-encoding-* vnc-enc-*Corentin Chary5-7/+7
For the same reason that we don't use vnc-authentication-sasl.c but vnc-auth-sals.c. Because it's tooooo long. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
