Bahadir Balban 329dc53982 FS0 compiles with the changes, also caught an unparanthesised double-statement 
if clause in lookup.c
 2008-02-14 21:23:49 +00:00
Bahadir Balban 1b387a1704 Implemented vfs_lookup_byvnum() close to what it should look like. 2008-02-14 15:46:30 +00:00
Bahadir Balban d3b6817887 Some more additional changes in same places. 2008-02-14 15:13:08 +00:00
Bahadir Balban a989e1f774 sys_readdir and memfs_readdir closer to targeted look and feel. 
We now have a single dirbuf of size PAGE_SIZE kept on the vnode. This is
to be used for directory contents only. The reason it's kept on FS0 is
because the contents are modified by calls such as mkdir or create, and otherwise
these would have been handled by mm0 on the page cache buffers, which wouldn't work.

Bahadir Balban 2440b5be61 Some efforts to adding better support for readdir 2008-02-14 12:08:21 +00:00
Bahadir Balban 60cce15a4d Some preliminary efforts to reading directory contents in fs0. 
Need to still decide whether content buffers are provided by mm0,
whether need to return them back to mm0, and the read count.

Bahadir Balban 0c7d2bbfd1 swapped write_mr() arguments. 
write_mr() now works as write_mr(mr_offset, mr_val), which makes sense.

Bahadir Balban 57420942ba Removed unnecessary printks, fixed few minor issues. 2008-02-09 15:48:10 +00:00
Bahadir Balban ba0e3ada21 Few more fixes. 
Boot files and tasks are now initialised together. Theads can ask for particular
space and thread ids, if they're unused. This enables us to get predefined ids for
known tasks such as the VFS task.

Fixes to README
Other minor fixes.

Bahadir Balban 938672f7c9 Changed the virt-to-phys debug breakpoint name to break_virtual 
Changed l4id_t type to integer to recognise negative id values like L4_ANYTHREAD.
Added an extremely simple script that cleans and builds everything in right order.

Increased boot pmds by one:
This is due to the fact that if the 1MB initial allocation area of the kernel is
not 1MB-aligned, it is ought to be mapped from the middle of one MB to next,
which requires 2 pmds.

Bahadir Balban cab2e8bdd3 Finished adding untested bare functionality vfs 
Finished adding untested shm syscalls.
Finished adding untested l4 send/recv helpers

Everything compiles. Now going to fix lots of bugs ;-)

Bahadir Balban 05e9028e90 Some more minor changes. 2008-01-22 13:26:19 +00:00
Bahadir Balban adf54578f8 Improvising on disk layout of simple unix-like filesystem. 
modified:   tasks/fs0/include/fs.h
	new file:   tasks/fs0/src/simplefs/sfslayout.h
 2008-01-18 15:20:46 +00:00
Bahadir Balban 66abb3d7f8 Added a public domain malloc temporarily. 
More changes to fs0, still improvising.
 2008-01-16 18:12:20 +00:00
Bahadir Balban c921197e69 A first step in writing a dynamically created bootfs for boot images. 2008-01-16 01:37:24 +00:00
Bahadir Balban 6bb5b45212 FS0 compiles now, with a mock-up rootfs. 
Having progress on vfs slowly but surely ;-)

Bahadir Balban 7a388f22b7 Removed all ignorable files from git. 
Previously python hex() would put an extra 'L' after printing out the
value and this would be trimmed in readelf.py. Now it doesn't seem to
do that so the lsd of the number was trimmed. This patch fixes that.
