2017-07-08 | added dedicated kernel entry to avoid address reordering under compiler ↵ | Andreas Baumann | |
optimization affect the entry poin 0x8800 of kernel_main (now kernel_entry) | |||
2017-07-05 | removed unneded volatile for text VIDEO_MEMORY (we should add the reference ↵ | Andreas Baumann | |
to "volatile is always wrong" | |||
2017-07-05 | removed superfluous context in vga driver (was not used) | Andreas Baumann | |
added dummy methods and driver_init for anonymous driver initialization | |||
2017-07-05 | tried to fix libc tests, currently they draw in too many dependencies | Andreas Baumann | |
and don't link. We have to separate libc better from the rest of the kernel code (kernel_panic, libc library initializers) | |||
2017-07-05 | 'mem' command shows memory usage of kernel heap now | Andreas Baumann | |
implemented a malloc/free and memory manager (simplest possible implementation, just allocating linearly and never freeing) | |||
2017-07-05 | fixed compilation errors due to unused variables | Andreas Baumann | |
2017-07-05 | some kernel code cleanup | Andreas Baumann | |
renamed 'proc' command to 'task' and make it show number of tasks and context switches | |||
2017-07-05 | fixed graphical screen refresh (a refreshScreen task) | Andreas Baumann | |
cleaned up code after interrupt_enable in main thread everything works again | |||
2017-07-04 | got scheduling of task A and B working (now graphics output and termination ↵ | Andreas Baumann | |
is broken) | |||
2017-07-02 | started to add task scheduling | Andreas Baumann | |
2017-07-02 | added ESC key in PS/2 keyboard driver | Andreas Baumann | |
allow pressing ESC in graphics mode to return to text mode | |||
2017-07-01 | do not call methods directly on desktop object, the desktop object could | Andreas Baumann | |
be derived, so go over the vtable (keyboard and mouse handlers in kernel.c) | |||
2017-07-01 | replaced some strange access to .base.base with casts of the class to the ↵ | Andreas Baumann | |
class needed to access the proper vtable | |||
2017-07-01 | got rid of superflous vtables in GUI class hierarchy | Andreas Baumann | |
2017-07-01 | fixed get_focus error in widget (called the wrong parent) | Andreas Baumann | |
the text widget reacts to mouse down and key events and appends text to the output buffer so we have text input in GUI mode | |||
2017-07-01 | restoring VGA text cursor in the right place | Andreas Baumann | |
2017-07-01 | readded -Werror and fixed some cast errors around memcpy | Andreas Baumann | |
2017-06-30 | almost got a complete mode switch (vga graphics back to text) working | Andreas Baumann | |
some cleanup in VGA driver code | |||
2017-06-30 | text widget has a constant buffer and owns the string to draw now | Andreas Baumann | |
(passing a const char * from a local stack context is not really a good idea!) added more efficiet draw method for characters in vga driver protected desktop for now against too often redraws (boolean global variable needs_redraw, this is later a soffisticated set-of-areas-to -redraw algorithm) | |||
2017-06-30 | playing with Z buffering in VGA driver | Andreas Baumann | |
2017-06-30 | added a third widget (for drawing fonts) | Andreas Baumann | |
fixed drawing races due to mouse interrupts | |||
2017-06-30 | added a VGA wait for retrace in graphics mode | Andreas Baumann | |
2017-06-30 | added a window to gui which is draggable by the mouse | Andreas Baumann | |
2017-06-29 | widget should be in kernel data section and not in local scopes of a stack | Andreas Baumann | |
2017-06-26 | nothing working in gui! | Andreas Baumann | |
2017-06-25 | fighting races and corrupted data on clang, funny behaviour on tcc, fine on ↵ | Andreas Baumann | |
gcc in desktop draw | |||
2017-06-25 | small unused variable fix | Andreas Baumann | |
2017-06-25 | we have a flickering mouse cursor and terrible redrawing of the desktop now :-) | Andreas Baumann | |
removed the font window for now, far too slow! | |||
2017-06-25 | put the mouse object into the global context so we can adjust the | Andreas Baumann | |
resolution when switching video modes | |||
2017-06-25 | fixed calculation of coordinates in text widget | Andreas Baumann | |
2017-06-24 | . | Andreas Baumann | |
2017-06-24 | font is shown as a text widget now | Andreas Baumann | |
fixed setting of vtable in derived classes still some local to screen coordinate calculation problem in text widget | |||
2017-06-24 | started to implement a widget showing text, the problem currently | Andreas Baumann | |
is the inheritance method in draw is not working correctly | |||
2017-06-24 | fixed the console output to VGA text mode to also wipe the rest of a line | Andreas Baumann | |
on newline | |||
2017-06-24 | minor font printing fixes | Andreas Baumann | |
2017-06-24 | printing whole ASCII font in VGA graphics mode | Andreas Baumann | |
2017-06-24 | made VGA graphical font smaller (we only want ASCII for now) | Andreas Baumann | |
some performance improvements in VGA graphics mode | |||
2017-06-21 | started to rewrite to use the main desktop widget | Andreas Baumann | |
2017-06-21 | much nicer calls when passing color constants | Andreas Baumann | |
2017-06-21 | improved VGA colors | Andreas Baumann | |
added basics of a desktop widget class | |||
2017-06-18 | started the widget framework | Andreas Baumann | |
2017-06-17 | added the most complex VGA mode (640x480x4, only timings for now) | Andreas Baumann | |
added graphics and text mode type parameter to vga_mode_t | |||
2017-06-16 | playing with VGA font distance and characters bei being on the head or mirrored | Andreas Baumann | |
2017-06-16 | switching mode text/graphics, text is distorted | Andreas Baumann | |
2017-06-16 | first character printed in graphics mode | Andreas Baumann | |
2017-06-16 | added a global kernel data structure, so we don't allocate the | Andreas Baumann | |
basic drivers on the stack of kernel_main added commands 'clear' to clear the screen and 'mode' to switch the mode of the graphics card (for testing) | |||
2017-06-16 | fixed loading of kernel in stage2 grossing 64k | Andreas Baumann | |
2017-06-15 | added a clear screen method to graphics mode VGA driver | Andreas Baumann | |

2017-06-15 | some speed tests | Andreas Baumann | |
