# To build:
|

|
|
||||||
To build and run (on any platform, without root privileges):
|
```sh
|
||||||
|
make
|
||||||
|
```
|
||||||
|
|
||||||
make gavin
|
### To run:
|
||||||
|
|
||||||
To enjoy the results (on a Linux/x86 machine):
|
```sh
|

Make a floppy with an ext2 filesystem (mke2fs /dev/fd0), mount it under /mnt/floppy.
|

# If your floppy drive is not /dev/fd0, edit lilo.conf appropriately

Over the years, we've seen a program that dumps core
|
|
||||||
if executed on a "wrong" architecture immediately (1984/mullender),
|
|
||||||
or after a while (2001/bellard). This entry will happily compile and
|
|
||||||
execute on any architecture - the trick is that the result, to be useful,
|
|
||||||
must be produced (and can only be enjoyed) on a particular architecture.
|
|
||||||
We have not decided yet whether to disallow this for future contests.
|
|
||||||
|
|
||||||
If you do not want to mess with a floppy and you use GRUB, see below
|
|
||||||
in the author's notes.
|
|
||||||
You can put additional text files in fs.tar for browsing with vi.
|
|
||||||
If you do not want to bother rebooting your computer at all,
|
|
||||||
see http://bellard.org/ for QEMU (Fabrice Bellard is an IOCCC 2001 winner),
|
|
||||||
but your experience will be limited (replace -DK=0 with -DK=1 in the Makefile,
|
|
||||||
and you will have to move the mouse to trigger the initial screen update).
|
|
||||||
|
|

```sh

|

|
|
||||||
This is a 32-bit multitasking operating system for x86 computers,
|
NOTE: If the version of your lilo is not 21.4, use the appropriate boot.b file.
|
||||||
with GUI and filesystem, support for loading and executing user
|
|
||||||
applications in elf binary format, with ps2 mouse and keyboard drivers,
|
|
||||||
and vesa graphics. And a command shell. And an application -
|
|
||||||
a simple text-file viewer.
|
|
||||||
|
|
||||||
The OS has ended up as a traditional monolith with one entry point
|
NOTE: If your floppy drive is not /dev/fd0, edit lilo.conf appropriately.
|
||||||
for syscalls, with apps treated as cooperative-multitasking tasks
|
|
||||||
that can be sent different messages (e.g. 'initialize', 'key hit',
|
|
||||||
'render to buffer') through their main entry point, and which will
|
|
||||||
return control to the OS having performed the necessary work.
|
|
||||||
Applications are are passed a pointer to their task structure,
|
|
||||||
which is partially defined by the OS, and partially for
|
|
||||||
the application's own use.
|
|
||||||
|
|
||||||
The program compiles into a tool to build a kernel image,
|
```sh
|
||||||
so having built the program, the makefile will run it,
|
lilo -C /mnt/floppy/lilo.conf
|
||||||
piping the output into a file called 'kernel'.
|
```
|
||||||
The makefile will then proceed to build a root filesystem image.
|
|
||||||
This involves rebuilding the program with different compiler flags,
|
|
||||||
then building a tar file containing the resulting programs
|
|
||||||
(the filesystem format supported by the OS is the tar-file format).
|
|
||||||
|
|
||||||
For further usage information see 'gavin_install.txt'.
|
Boot from the floppy on an x86 machine with a PS/2 keyboard and mouse.
|
||||||
|
Move the window away from the corner.
|
||||||
|
|
||||||
The filenames 'vi' and 'sh' are significant, and should not be changed.
|
```sh
|
||||||
|
vi gavin.c
|
||||||
|
```
|
||||||
|
|
||||||
Known 'features'.
|
Scroll the file with up-arrow and down-arrow
|
||||||
|
|
||||||
Known issues are really too plentiful to list.
|
```sh
|
||||||
|
sh
|
||||||
|
```
|
||||||
|
|
||||||
If the mouse pointer goes off the left hand side of the screen
|
Can have several shell windows:
|
||||||
it will reappear on the right, and vice-versa.
|
|
||||||
If it goes off the top or bottom, it will go and corrupt some memory.
|
|
||||||
|
|
||||||
The file system is kinda optimistic about matching names, so,
|
```sh
|
||||||
for example if you type the command 'shell' into a command-line
|
vi gavin.hint
|
||||||
it will execute the program 'sh' - close enough a match for it.
|
./prim
|
||||||
|
```
|
||||||
|
|
||||||
The elf binaries are not loaded at the correct address,
|
Press and hold any key.
|
||||||
and their entry point must be the start address of the text segment.
|
|
||||||
|
|
||||||
The keyboard driver can cope with the basic alpha-numeric keys,
|
## Judges' comments:
|
||||||
but gets confused by fancy things like 'shift' or 'backspace'.
|
|
||||||
|
|
||||||
In the text-file viewer, 'vi', the up/down and pgup/pgdn keys
|
Over the years, we've seen a program that dumps core
|
||||||
scroll up or down by one line. There is nothing to stop you
|
if executed on a "wrong" architecture immediately (1984/mullender),
|
||||||
[from] scrolling above the top of the file, and pressing any
|
or after a while (2001/bellard). This entry will happily compile and
|
||||||
other keys may have an undefined effect.
|
execute on any architecture - the trick is that the result, to be useful,
|
||||||
|
must be produced (and can only be enjoyed) on a particular architecture.
|
||||||
|
We have not decided yet whether to disallow this for future contests.
|
||||||
|
|
||||||
The x86 is bootstrapped into 32bit mode in 6 instructions,
|
If you do not want to mess with a floppy and you use GRUB, see below
|
||||||
with 4 more to set up data/stack segments and a stack-pointer
|
in the author's notes.
|
||||||
to allow C code to be run. On top of this there are also about
|
You can put additional text files in fs.tar for browsing with vi.
|
||||||
a dozen instructions to switch the video card into graphics mode.
|
If you do not want to bother rebooting your computer at all,
|
||||||
All in all, a relatively tiny number of instructions next to
|
see http://bellard.org/ for QEMU (Fabrice Bellard is an IOCCC 2001 winner),
|
||||||
the size of the C program. Also, the string is mostly composed
|
but your experience will be limited (replace -DK=0 with -DK=1 in the Makefile,
|
||||||
of data - a Linux-esque kernel header for the bootloader,
|
and you will have to move the mouse to trigger the initial screen update).
|
||||||
protected mode descriptor tables, keyboard maps, etc.
|
|
||||||
(I should also mention that it contains mini functions
|
|
||||||
to perform an x86 'in' and 'out' instruction - to allow
|
|
||||||
the keyboard & mouse to be driven from C code).
|
|
||||||
|
|
||||||
Porting to another architecture should be relatively easy* -
|
The judges were able to write a few more programs to run on this OS
|
||||||
the string simply needs be replaced with one containing
|
What are the limitations for such programs?
|
||||||
data & code suitable for the new target platform.
|
What you can do and what you cannot do in such programs?
|
||||||
Accesses to data in the string are made relative to the define 'V',
|
|
||||||
so these may need updating as appropriate (0x90200 is the address
|
|
||||||
at which a Linux bootloader loads an x86 kernel image).

return control to the OS having performed the necessary work.
|
||||||
|
Applications are are passed a pointer to their task structure,
|
||||||
|
which is partially defined by the OS, and partially for
|
||||||
|
the application's own use.
|
||||||
|
|
||||||
|
The program compiles into a tool to build a kernel image,
|
||||||
|
so having built the program, the makefile will run it,
|
||||||
|
piping the output into a file called 'kernel'.
|
||||||
|
The makefile will then proceed to build a root filesystem image.
|
||||||
|
This involves rebuilding the program with different compiler flags,
|
||||||
|
then building a tar file containing the resulting programs
|
||||||
|
(the filesystem format supported by the OS is the tar-file format).
|
||||||
|
|
||||||
|
For further usage information see 'gavin_install.txt'.
|
||||||
|
|
||||||
|
The filenames 'vi' and 'sh' are significant, and should not be changed.
|
||||||
|
|
||||||
|
### Known 'features'
|
||||||
|
|
||||||
|
Known issues are really too plentiful to list.
|
||||||
|
|
||||||
|
If the mouse pointer goes off the left hand side of the screen
|
||||||
|
it will reappear on the right, and vice-versa.
|
||||||
|
If it goes off the top or bottom, it will go and corrupt some memory.
|
||||||
|
|
||||||
|
The file system is kinda optimistic about matching names, so,
|
||||||
|
for example if you type the command 'shell' into a command-line
|
||||||
|
it will execute the program 'sh' - close enough a match for it.
|
||||||
|
|
||||||
|
The elf binaries are not loaded at the correct address,
|
||||||
|
and their entry point must be the start address of the text segment.
|
||||||
|
|
||||||
|
The keyboard driver can cope with the basic alpha-numeric keys,
|
||||||
|
but gets confused by fancy things like 'shift' or 'backspace'.
|
||||||
|
|
||||||
|
In the text-file viewer, 'vi', the up/down and pgup/pgdn keys
|
||||||
|
scroll up or down by one line. There is nothing to stop you
|
||||||
|
[from] scrolling above the top of the file, and pressing any
|
||||||
|
other keys may have an undefined effect.
|
||||||
|
|
||||||
|
The x86 is bootstrapped into 32bit mode in 6 instructions,
|
||||||
|
with 4 more to set up data/stack segments and a stack-pointer
|
||||||
|
to allow C code to be run. On top of this there are also about
|
||||||
|
a dozen instructions to switch the video card into graphics mode.
|
||||||
|
All in all, a relatively tiny number of instructions next to
|
||||||
|
the size of the C program. Also, the string is mostly composed
|
||||||
|
of data - a Linux-esque kernel header for the bootloader,
|
||||||
|
protected mode descriptor tables, keyboard maps, etc.
|
||||||
|
(I should also mention that it contains mini functions
|
||||||
|
to perform an x86 'in' and 'out' instruction - to allow
|
||||||
|
the keyboard & mouse to be driven from C code).
|
||||||
|
|
||||||
|
Porting to another architecture should be relatively easy* -
|
||||||
|
the string simply needs be replaced with one containing
|
||||||
|
data & code suitable for the new target platform.
|
||||||
|
Accesses to data in the string are made relative to the define 'V',
|
||||||
|
so these may need updating as appropriate (0x90200 is the address
|
||||||
|
at which a Linux bootloader loads an x86 kernel image).
|
||||||

### [2004/gavin](2004/gavin/gavin.c) ([README.md](2004/gavin//README.md))
|
||||||
|
|
||||||
|
Segmentation fault occurs when running `gavin` to produce the kernel:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
./gavin > kernel
|
||||||
|
```
|
||||||
|
|
||||||
|
When trying to link `gavin.o` to produce `sh`, the linker generates:
|
||||||
|
|
||||||
|
```
|
||||||
|

In case recent modification are part of the problem, here is a full disclosure
|
