[Manrix-devel] Updates (source and image ).

[Manish R. <reg...@gm...>]

Hi all,
  I have updated the both the source codes and Floppy image of ManRiX. 
The CVS server is not updated. I will do it as soon i get access to
Unix/Linux Box.

Updates:

1) Source Codes for File Manager.
      The file manager source code contains
      VFS code + ext2 fs code + buffer cache code.

2) Sources for ATA compatible Disk Controllers.
    IT can either coexist with file manager (for speed)
 or run as a seperate server.
   Can be configured at compile time.

3) Microkernel:

- Dup System Call added.
- mmap fixed. Now the address is first allocated from VM manager for
Anonymous map.
- exit problem fixed. Now the exit works on call during Signal delivery.
- exec works (weird behaviour on first page fault).
- vfork works perfect (Child guranteed to run first. 
  Parent guranteed to run only after child either do exec or exit.)
- fork works (vm design issue; how to handle shadow Objects????)
- message Passing; MSG_LONG_RECEIVE added; Now long messages can also
be received.
- message Passing; MSG_MAP_* problem solved; 
  Message can now be passed through page table mapping.
- TLB flushed after each page table manipulation. (thanks to Brenden Trotter)
- argc, argv, and env now works for both exec'd programs and modules
loaded by grub.

(see changelog.txt  files...) 

4) LIBC:
   A lot of functions added.(i have not created a changelog)...

5) small programs like 
 init, logd, login (Incomplete).


I know the project is going on very slowly. This is what happens with
one man Army. What all it takes is TIME.

HELP:
  Any help is highly appriciated in LIBC. There are thousands of
functions yet to be written (ANSI + POSIX).

Please run the codes and give me feedbacks.... 
(NOTE: The exec'd process has problem after first page fault. )

regards
