- The vm86 reflection code contains a dirty hack: the vm86_exc1 function
in vm86-exc.c hardcodes the int to be reflected...
This should be fixed in some way!!!
FIXED (and seems to be working very well...)
- Now, the registers structure should be fixed: move the flags field to the
other side of the structure (adding the CS and EIP fields), so that
we will not have to push flags and explicitly move it anymore...
DONE
- Fix problems with ASs and INTs (see kl/cxsw-1.s and xlib/exc.s)
Done! At least it doesn't crash :)
Must check in some way if the stack is correct or not...
I checked it, and it seems to be ok...
- verify that only the needed .o files are linked (see -DPROFILE); provide
a lightweight implementation of ``message'' (currently remapped on
cprintf) that does not require linking libm
- profile and optimize the event management code
- rewrite cons.c isolating the parts making assumptions on memory spaces and
improving efficency (window-based functions can be implemented
separately)
- pentium timestamp conter code... Integrate it in timer code and event
management
Assigned to Gerardo
- provide some macro for int-based and call gate-based system calls
Done for INT: see examples/syscalls.c
- begin to implement some serious code using OSLib:
1) some simple multithreading executive based on cooperative and
preemptive scheduling, message-based or based on shared
memory and semaphores...
2) some real small kernel, separating it from application code
3) as 2), but with different address spaces for kernel and
application
...
- fix the eXtender in order to be fully multiboot compliant (no extension to
the standard multiboot structure: we can use memory maps). Upgrade it
to the latest version of the standard. Implement modules loading
== Some work has been done... Now the eXtender can load MB compiant images
and manages modules.
== Now everything is compatible with the latest MB standard (the loader
name is used)
o Still to do: the memory map stuff & module parameters
- what about fixing that _NOH4_ story?
