| 2019-05-02 | tried to test on real Unisys, power-cycles, as in bochs | Andreas Baumann | |
| 2017-08-10 | renamed network write to network send | Andreas Baumann | |
| 2017-08-10 | forgot to set transmitting after writting (rtl8139) | Andreas Baumann | |
| 2017-08-10 | more testing with UDP | Andreas Baumann | |
| 2017-08-10 | some renamed in ethernet/rtl8139 | Andreas Baumann | |
| don't try tp play with the ethernet CRCs, they belong to layer 2 OSI, the firmware of the network card rtl8139: computing packet size correctly (sizeof uint32_t of the CRC was part of the payload len) | |||
| 2017-08-08 | sending sort of an ARP reply over the rtl8139 driver | Andreas Baumann | |
| 2017-08-06 | some cleanup in ethernet constants | Andreas Baumann | |
| sending back an ARP packet rtl8139: started to implement write (work in progress) | |||
| 2017-08-02 | added an IPv4 module, currently containg an address to string function | Andreas Baumann | |
| started to add ARP packet definition, reading and printing ARP request now some renames in networking layer | |||
| 2017-08-02 | introduced a network library, added ethernet structure, moved | Andreas Baumann | |
| generic stuff out of the network driver, kernel now sees ARP messages and prints src and dst MAC addresses | |||
| 2017-08-01 | freeing network data in handler and printing CRC in rtl8139 | Andreas Baumann | |
| 2017-08-01 | correctly receiving data in the rtl8139 driver and passing it to the network | Andreas Baumann | |
| handler, in Qemu user network we see complete ARP requests now (sent by Qemu itself presumably to update it's 'router' table (an external telnet localhost 8080 is needed to trigger that) | |||
| 2017-08-01 | sucessfully enabled DMA transfers in RTL8139 driver | Andreas Baumann | |
| 2017-08-01 | we can receive network events, but the receive buffer remains empty | Andreas Baumann | |
| this is because we must enable DMA transfering on the PCI bus (bus master enable) | |||
| 2017-07-27 | work on rtl8139 driver, can trigger interrupts now | Andreas Baumann | |
| 2017-07-27 | receiving the first network interrupts | Andreas Baumann | |
| 2017-07-24 | added print_name method to all drivers | Andreas Baumann | |
| removed superfluos empty methods in abstract drivers moved printing of info to method in rtl8139 driver | |||
| 2017-07-24 | sorted out the rtl8139 submodels | Andreas Baumann | |
| 2017-07-23 | printing vendor id of rtl8139 driver, started to set configuration | Andreas Baumann | |
| 2017-07-23 | reading and printing MAC address int RTL8139 driver | Andreas Baumann | |
| 2017-07-22 | started to code RTL8139 network driver, for now setting io_base and IRQ | Andreas Baumann | |
| 2017-07-22 | separated video driver in a virtual video driver and a specific | Andreas Baumann | |
| VGA video driver | |||
| 2017-07-22 | moved color handling to video driver from generic VGA driver | Andreas Baumann | |
| 2017-07-21 | .. | Andreas Baumann | |
| 2017-07-21 | changed video mode management, moved to video driver, | Andreas Baumann | |
| the VGA driver registers his specific mode data with the video driver kernel function now use virtual functions of the video driver | |||
| 2017-07-20 | started to abstract video drivers | Andreas Baumann | |
| 2017-07-20 | added a virtual network driver interface, made the dummy RTL8139 driver a ↵ | Andreas Baumann | |
| specialization of it (nothing is functional there yet) | |||
| 2017-07-20 | added a virtual keyboard driver interface, made the PS/2 keyboard a ↵ | Andreas Baumann | |
| specialization of it | |||
| 2017-07-18 | added a virtual mouse driver interface, made the PS/2 mouse a specialization ↵ | Andreas Baumann | |
| of it | |||
| 2017-07-16 | introduced classes of driver types (graphics, mouse, keyboard, network, etc.) | Andreas Baumann | |
| removed direct vga_init from kernel.c, using pci for this now, get the driver of type graphics from driver_manager | |||
| 2017-07-16 | moved registering of mouse/keyboard interrupts into the driver activation ↵ | Andreas Baumann | |
| instead of having them directly in kernel.c also more standardization of the driver init functions (mouse set_resolution instead of constructor parameters res_x and res_y) | |||
| 2017-07-15 | started to make driver construtors similar (keyboard, mouse) | Andreas Baumann | |
| passing context around to pci scanning function for driver initialization | |||
| 2017-07-15 | reworked driver init and vtable, taking the interrupt manager and the context | Andreas Baumann | |
| as parameters when creating a driver | |||
| 2017-07-15 | mouse and keyboard are now allocated driver pointers | Andreas Baumann | |
| 2017-07-15 | added a dummy RTL8139 network driver | Andreas Baumann | |
| added register interrupt handler methods to drivers (but I'm pretty unsure about them) setting network in qemu startup and using RTL8139 emulation drivers | |||
| 2017-07-14 | removed stddef.h and limits.h (come with the compiler header files) | Andreas Baumann | |
| added a stub stdint.h (only sometimes comes with the compiler) added a guide on cross compiling adapted to cross compilation, for now tcc works | |||
| 2017-07-12 | added segment_size to vga mode structure, using for memcpy in Z buffer | Andreas Baumann | |
| refreshing the video memory and when allocating the Z buffer | |||
| 2017-07-10 | VGA Z-buffer is now dynamically allocated and freed | Andreas Baumann | |
| memory management can reuse the last pointer malloced if freed again | |||
| 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 superfluous context in vga driver (was not used) | Andreas Baumann | |
| added dummy methods and driver_init for anonymous driver initialization | |||
| 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 | |||
| 2017-07-02 | simplified some driver manager code around calling virtual driver methods | Andreas Baumann | |
| declared method tables const per class | |||
| 2017-07-02 | some more vtable initialization fixes | Andreas Baumann | |
| 2017-07-01 | tested with pcc, works | Andreas Baumann | |
| removed some weird comments in vga_font.h troubling pcc | |||
| 2017-07-01 | added a preprocessor guard to vga_font.h | 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 | |
