or while a section of code is running with interrupts disabled (with the
exception of the initial kernel startup), the page fault handler will
now panic, to give you the chance to fix the bug.

thread_exit() for now prints a warning if it was called with interrupts
disabled.
Fixed a bug in thread_exit2() that restored the interrupts too early,
instead of simply enabling them (and restoring them later) [found by
Marcus O. great debug additions].
Fixes for the khash changes.

leak fixed, some other bugs fixed, removed the global queues as there weren't
needed and used at all, moved to the other hash table implementation
(because the new_hash_table stuff was buggy). Should really work okay now :-)
Added the last missing function get_next_loaded_module_name() - I am not
sure the Be version works this way, but we could easily change that after
actually having found out how that one is really working.

Fixed some minor a larger issues (one memory corruption due to the use of FD_ZERO()).
notify_select_event() is no longer binary compatible (hasn't been used on R5).
Added syscalls for select/poll in the syscall dispatcher.
Fixed some debug output in fd.c, adapted for the new notify_select_event()

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1566 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed sys_read_stat() to sys_read_path_stat() - sys_read_stat() is now
the fd operation (same for the corresponding write call).
Removed the sys_write_attr_stat() call because it is no longer needed.
Added stat(), fstat(), and other POSIX calls to the kernel - many are still
missing (mainly from stdio).
Added symbols (but no implementation) for unistd.h's process id functions.
Adapted libroot calls that used sys_read_stat() before to the new architecture.
module.c and bus_man.c now use stat() directly instead of the sys_read_path_stat()
call.

Fixed a very unlikely race condition in create_sem_etc() (can only happen if
that call isn't used properly).
Fixed some wrong return values (i.e. B_BAD_TEAM_ID wasn't returned anywhere).
Optimized _get_next_sem_info(): it now only grabs the semaphore lock

also fixed a bug, because fs_read_info()/fs_write_info() already locked the
mutex before calling find_mount().
Implemented the file system API for attribute directories, and index
directories.
Introduced a new macro FS_MOUNT_CALL() to call fs ops directly from the
mount structure.
get_new_fd() now panics if it is called with an unknown fd type.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1189 a95241bf-73f2-0310-859d-f6bbb57e9c96
Reimplemented file system handling, it's now loading file systems on an
on-demand basis - code is not tested yet, but should work!
That also fixed a bug that was in that code before (the image was not
unloaded in case of an error in vfs_load_fs_module()).
Renamed fs_id to mount_id.
Renamed all global variables to have the 'g' prefix in vfs.c.

new_file_fd() is now called get_new_fd(), and can also create fds for other
types as well. Furthermore, it lost some memory if it couldn't allocate a
new fd.
Implemented most of the VFS attribute API (kernel internal only), only
remove_attr(), and rename_attr() is missing for now.

This change also introduces a lot of new warnings concerning printf format
anomalies. Please do NOT fix them. Currently, int32 (and also status_t)

Added syscalls for, and implemented sys_create_link(), sys_remove_dir().
Implemented link(), unlink(), rmdir().
Fixed the inconsistent path buffer handling in the user|sys vfs functions; the
path buffer is now exactly SYS_MAX_PATH_LEN from userland (incl. terminating
null byte).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@748 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced the unused syscall for getdtablesize() with one for access().

sys_setcwd(), and sys_write_stat().
Added missing sys_fstat(). Removed duplicated prototypes in syscalls.h

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@592 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added needed syscalls to access symlink support from userland
- implemented lstat(), symlink(), and readlink()
- added dev_t to ktypes.h (for now - should be in a public header anyway)
- added symlink support to the "ls" command (now calls lstat() and shows the
link target with the -l option)
- changed the sys_read_stat() call to support symlinks, and updated files
using that function (it gets an extra argument: bool traverseLink)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@560 a95241bf-73f2-0310-859d-f6bbb57e9c96
- if the path name exceeded about 56 bytes, the function would have seg-faulted
- the calculation to decide if there is an extra region for the bss needed was wrong -
that caused the kernel to be not able to load certain executables
Also, fixed a warning, and cleaned up the above mentioned function a bit, added
some more comments.

config_manager and busses works, and this is a large correction based on
my current working thoughts.
I also think we need to have a new interface between the bus modules and
the config_manager to allow them to work together. I have some ideas
on it and will start fleshing it out next week.
This update basically moves all PCI stuff back to the PCI module and
cleans up config_manager.c. We now print a small amount of info for
devices and more for bridges. My system only has a single bridge, but if
anyone has a more exotic system and tries this can they let me know
what sort of results they see?

Fixed many bugs.
Now, the vfs_ prefix is for functions that are called by other parts of the
kernel. file_ is for file related stuff, dir_ for directory related, and
common_ for both, fs_ for general file system stuff.
Put all prefixed functions together in the source.
Implemented (currently without a user/sys call) opening/creating of entry_refs,
and node_refs (the latter for opening directories only).
Moved vfs_dup(), and vfs_dup2() to fd.c, fd_dup(), and fd_dup2().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@351 a95241bf-73f2-0310-859d-f6bbb57e9c96
we now differntiate between an I/O interrupt (ie one that is likely
to be triggered by a device on the system using an IRQ between
0 and 15) and one that we're creating to allow us to have functions
called for events, ie a software interrupt. Behaviour is all
commented in the file int.c, but you need to make sure that you call the
correct version.
install_io_interrupt_handler now needs an IRQ value between 0 and 15 and
will treat the irq as one it needs to enable/disable
install_interrupt_handler is for software interrupts and is essentially
the function we had.
For mroe read the comments in the file.

I removed all those insane INSANE() debug output and found what made

because of that.

- make pci into a true module now.
- the pci module builds and keeps a linked list of devices it finds, with
a filled in pci_info structure
- pci module detects (at runtime) whcih config mech to use, though to date
only mech 1 is implemented
- pci module does sanity check and warns if it fails
- config manager loads pci module and calls get_nth_pci_info to iterate
through the list printing details
- pci is no longer called directly from the bus init function
there is still lots to do and I've tried to make sure that there are plenty
of comments in the pci.c file. I've also left the previous code in
place until we move on a little further when it will be removed.
This has been working with no problems on my system and doesn't change
any functionality as we don't have any devices that need PCI in our build

If people can test and confirm this works. It works here and has solved
all the issues I was trying to fix.

Provide more info when a duplicate module name is detected during a scan.
Remove some code we no longer use.

Minor bug fixes.
fd_close() now doesn't have to call remove_fd() anymore - it's now called
in user|sys_close(), fd_close() is now only called in the last put_fd().
Cleanup, improved debug output (without any warnings).

manager module. As time goes on we can start fleshing these out.

Fixed some bugs in fd.c (how many more bugs can be in a small file like this? :-).
Added the syscalls for sys_open_dir(), and sys_create_dir().

functions. sys_create() now returns an fd of the open file (some code in the
kernel shell already depend on this).
Moved the seek functions to fd.c.
Updated all internal file systems to a new and updated API.
vfs.c is not cleaned up well, but also has some bug fixes.

the warnings about sem_info and port_info (defined in kernel/OS.h)

Remove the iso9660 stuff from the build as it's no longer being
maintained and never did anything anyways :)
