2713 6002 d 1 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 6002 d 2 h decky /trunk/kernel/ prettyprint output  
2711 6006 d 21 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6006 d 21 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6006 d 23 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6007 d 0 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6007 d 1 h jermar /trunk/uspace/ Support for mkdir().  
2706 6007 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6007 d 17 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 6008 d 4 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2703 6008 d 23 h jermar /trunk/kernel/arch/amd64/ Grow the initial identity mapping from 64M to 4G.
We should not allocate GDT's from above 4G or the amd64 will occassionally
triple-fault again.
 
2702 6009 d 2 h decky /trunk/kernel/arch/ia32/src/mm/ change cstyle to human-readable form  
2701 6009 d 4 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2700 6015 d 2 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2699 6015 d 16 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2698 6015 d 22 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2697 6019 d 3 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2696 6019 d 6 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2695 6019 d 6 h decky /trunk/contrib/conf/ make msim.conf compatible with MSIM 1.3.x  
2694 6020 d 19 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6021 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2692 6022 d 22 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2691 6024 d 20 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
 
2690 6025 d 18 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2689 6025 d 19 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6025 d 19 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6025 d 19 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6025 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6025 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2684 6027 d 20 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2683 6027 d 23 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
 
2682 6028 d 2 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 6028 d 3 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6028 d 3 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
 
2679 6031 d 19 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.
 
2678 6033 d 22 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
 
2677 6033 d 23 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
 
2676 6034 d 6 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2675 6034 d 18 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().
 
2674 6034 d 18 h jermar /trunk/uspace/ Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3.
