The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.
- Now cursor can appear in two different modes (if supported by terminal)
- Simplified text cursor handling.
- Show a status bar if terminal has enough lines for it. Added "show IPS" output
there unless display library option "hideIPS" is used.
- The X gui behaviour should be unchanged.
- RFB / vncsrv: cursor shape fixes.
- Changed format of the font parameters to fix "double width" characters.
- Restore guest charmap after leaving gui console.
- Now using text_update_common() for the new text update API in addition to the
graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
draw_char(). The method set_font() is optional and it can be used to update
font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
and h/v pel panning are supported by the RFB gui. The legacy text_update()
method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.
- Added support for split screen mode and horizontal pel panning.
- Text mode cursor now correctly visible independent from blink state.
- Workarounds for the existing text_update() API.
set accordingly.
TODO #1: Text mode features split screen and h/v pel panning missing for now.
TODO #2: Show error messages related to dialogs in message boxes.
- Enter command mode with F7 key only, but no modifier pressed.
- Pressing / releasing modifier key only doesn't leave command mode.
- Changed some headerbar button access keys using modifiers (e.g. shift + c
calls config button handler). See user doc for all supported keys.
with keypress combination. This feature is currently supported by the x and
sdl2 guis only and it can be activated with the "cmdmode" (command mode)
display library option. If enabled, pressing the F7 key enters this mode (shown
in the leftmost statusbar item) and the next keypress (except F7) is not sent
to the emmulated keyboard. If the key is supported, the associated action is
performed. Both x and sdl2 support calling the handlers of 8 headerbar buttons.
The sdl2 gui additionaly supports toggling fullscreen / windowed mode.
Supported keys:
c - Press the Copy button
e - Press the Config button
f - Toggle fullscreen mode (sdl2 only)
n - Press the Snapshot button
o - Press the Power button
p - Press the Paste button
r - Press the Reset button
s - Press the Suspend button
u - Press the User button
F7 - Send F7 keypress to emulation
TODO: add support for other guis.
Moved status bar update to the gui thread and added a new event type called
BX_ASYNC_EVT_STATUSBAR to invoke it. Changed size and style of the status bar
items.
- moved code that sends the framebuffer update to the flush() method.
- method clear_screen() now sets up an update region to work as expected.
- fixed and improved function rfbAddUpdateRegion().
- added new function rfbSetUpdateRegion() to simplify code.
This patch fixed an integer overflow issue when restoring a snapshot whose parameters that are larger than ULONG_MAX.
We run into this issue when restoring a Windows snapshot whose pc_system.ticksTotal exceeds ULONG_MAX, which caused the subsequent confusion in bx_virt_timer_c::timer_handler which relies on pc_system.ticksTotal to function correctly.
