ui: move all ui components in ui/

2010-07-26T22:35:54+00:00

Move sdl, vnc, curses and cocoa UI into ui/ to cleanup the root directory. Also remove some unnecessary explicit targets from Makefile. aliguori: fix build when srcdir != objdir Signed-off-by: Corentin Chary Signed-off-by: Anthony Liguori

vnc: rich cursor support.

2010-05-24T20:18:24+00:00

Uses VNC_ENCODING_RICH_CURSOR. Adding XCURSOR support should be possible without much trouble. Shouldn't be needed though as RICH_CURSOR is a superset of XCURSOR. Signed-off-by: Gerd Hoffmann Signed-off-by: Anthony Liguori

vnc: Fix artifacts in hextile decoding

2010-01-07T13:55:34+00:00

02c2b87 introduced a regression whereas the foreground color in a hextile update was not being properly invalidated leading to artifacts. It's still necessary to explicitly invalidate the foreground color with a SubrectColoured tile even though we no longer send a foreground color as part of the tile.

vnc: hextile: do not generate ForegroundSpecified and SubrectsColoured tiles

2009-12-18T17:26:25+00:00

This violates the RFB specification (section 6.6.4). It happens to work with most clients but it's still wrong. Reported-by: Yaniv Kaul Signed-off-by: Anthony Liguori

single vnc server surface

2009-08-10T18:05:30+00:00

This patch removes the server surface from VncState and adds a single server surface to VncDisplay for all the possible clients connected. Each client maintains a different dirty bitmap in VncState. The guest surface is moved to VncDisplay as well because we don't need to track guest updates in more than one place. This patch has been updated to handle CopyRect correctly and efficiently.

vnc: cleanup surface handling, fix screen corruption bug. (Gerd Hoffmann)

2009-03-20T15:59:14+00:00

This patch killes the old_data hack in the qemu server and replaces it with a clean separation of the guest-visible display surface and the vnc server display surface. Both guest and server surface have their own dirty bitmap for tracking screen updates. Workflow is this: (1) The guest writes to the guest surface. With shared buffers being active the guest writes are directly visible to the vnc server code. Note that this may happen in parallel to the vnc server code running (today only in xenfb, once we have vcpu threads in qemu also for other display adapters). (2) vnc_update() callback tags the specified area in the guest dirty map. (3) vnc_update_client() will first walk through the guest dirty map. It will compare guest and server surface for all regions tagged dirty and in case the screen content really did change the server surface and dirty map are updated. Note: old code used old_data in a simliar way, so this does *not* introduce an extra memcpy. (4) Then vnc_update_cient() will send the updates to the vnc client using the server surface and dirty map. Note: old code used the guest-visible surface instead, causing screen corruption in case of guest screen updates running in parallel. The separate dirty bitmap also has the nice effect that forced screen updates can be done cleanly by simply tagging the area in both guest and server dirty map. The old, hackish way was memset(old_data, 42, size) to trick the code checking for screen changes.

exploiting the new interface in vnc.c (Stefano Stabellini)

2009-01-15T22:17:38+00:00

This patch exploits the new DisplaySurface and PixelFormat structures in vnc, making the code easier to read allowing further improvements. Compared to the last version I fixed a bug that prevented the hextile encoding from working properly.
