Implemented the possibility for built-in modules - they have to be listed
in sBuiltInModules in module.c to be registered automatically.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7318 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added system_info.c to the build.
Added stats support functions to sems & ports.

Incorporated NewOS change 1930: sends the parent SIGCHLD if the team
goes away.
create_thread() now returns B_BAD_TEAM_ID when the team is in death state
instead of ERR_TASK_PROC_DELETED.
Cleaned headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6997 a95241bf-73f2-0310-859d-f6bbb57e9c96
from thread_exit().
Removed team_remove_team_from_hash() as it's no longer necessary.
Also incorporated NewOS change 1930: maintain the parent/children lists.
Cleaned up the headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6996 a95241bf-73f2-0310-859d-f6bbb57e9c96
as already suggested in my earlier comment.
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6993 a95241bf-73f2-0310-859d-f6bbb57e9c96
Took the chance and cleaned it up even more; this change is not a functional change.

Taken from NewOS, thanks to Travis for pointing this out.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6971 a95241bf-73f2-0310-859d-f6bbb57e9c96
Saved the port_entry.closed member and now set the capacity to 0, since
it is not used any longer (reduces the size of the port table).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6956 a95241bf-73f2-0310-859d-f6bbb57e9c96
could be changed at startup (adapted to system properties).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6955 a95241bf-73f2-0310-859d-f6bbb57e9c96
Right now, it allocates/frees the msgs from the kernel heap for every
message sent - that might be too slow for real world usage.
Also removed all known race conditions from the code.
Not tested at all yet, though.

the info from the wrong end of the queue.
find_port() did not return the correct error codes.
write_port_etc() checked incorrectly for a deleted semaphore.
B_WOULD_BLOCK would let various functions print out a warning for no reason
(the comments in the code actually didn't fit to the implementation).
"total_count" was counting the number of messages written, not those that
have been read (as the BeBook says).
Thanks to Bill Hayden who reported a lot of these.
Added TRACE macro and moved some of the dprintf()s to that.
Added/fixed some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6901 a95241bf-73f2-0310-859d-f6bbb57e9c96
run. Also create_port() now changes the port ID only when the port lock is
grabbed, so that we don't need to acquire the port list lock in find_port().
Removed setting lock to "0" in create_port() because if it's not 0 in the
first place, there is something seriously wrong (should add an assert there).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6897 a95241bf-73f2-0310-859d-f6bbb57e9c96
I don't know which part of me has written the previous version, but
it seems not have been supervised by a brain while doing it.
The read requests are now maintained per inode (as it has to be),
and there is one read lock per request.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6891 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved wait_for_team() into the exported kernel API region.
Added missing call for _user_get_current_team().
Made the team_kill_team() call to the BeOS compatible kill_team().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6868 a95241bf-73f2-0310-859d-f6bbb57e9c96
else is not found here. The BeOS kernel also exports these two *_etc()
functions, and we might want to do that, too.
{receive|send}_data() are now interruptible from userland, but not when
called from the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Copied over the function description of user_strlcpy() from x86/arch_cpu.h

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6697 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented the B_CURRENT_TEAM mechanism for _get_next_sem_info().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6691 a95241bf-73f2-0310-859d-f6bbb57e9c96
out the port_info setup to fill_port_info(), implemented the B_CURRENT_TEAM
behaviour as described in the BeBook (well, almost, since B_CURRENT_TEAM
is not defined in R5, it's just "0"), improved error checking.
Cleaned up user syscalls.
Replaced SYS_MAX_OS_NAME_LEN with B_OS_NAME_LENGTH.
Banned strncpy().
Added our license.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6685 a95241bf-73f2-0310-859d-f6bbb57e9c96
Cleaned up _get_thread_info() & _get_next_thread_info() - factored out
the thread_info setup into fill_thread_info().
Is now using team_is_alive() instead of team_get_team_struct().
Replaced SYS_MAX_OS_NAME_LEN with B_OS_NAME_LENGTH.
Banned strncpy() in favor for strlcpy().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6683 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced some old error codes.
Explained a bit more how to solve a race condition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6681 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed old error codes.
Replaced the DEVFS_IOCTL_* with their Be equivalents. Note, the related
functions are not user space safe yet. But since the devfs will be
almost rewritten, there is no point in changing it now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6679 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added our license to the updated source files.
Minor cleanup.

a comment what we could do to further improve performance.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5788 a95241bf-73f2-0310-859d-f6bbb57e9c96
forgotten about different address spaces with direct (unbuffered) pipe transfer,
shame on me.

always zeroed anyway.
cmd_help() is now able to print out help about the specified command
only - it will also print out all aliases of that command. Reduced
the distance between the command name and its description; NULL
descriptions are now also allowed.
There is now a find_command() function that's used throughout the
module. Like in the Be debugger, it will now also accept partial
matches, i.e. "co" will most probably match "continue" (as long as
there is no new "co*" command added by another component). It will
first try to find an exact match, and only if that failed it will
search for a partial match.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5307 a95241bf-73f2-0310-859d-f6bbb57e9c96
Disabled dbg_get_serial_debug(); it's only used temporarily in the keyboard
device (and I removed its usage there, too).
Added "continue", "exit", and "es" commands as in the Be kernel debugger
(they will all exit the debugger and try to continue normal kernel execution).
Reordered the sources so that public kernel API is together.
Added a _user_debug_output() syscall (not yet activated) which dumps to the
kernel's serial output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5305 a95241bf-73f2-0310-859d-f6bbb57e9c96

Removed the STREAM_TYPE_* definitions, it's now using the stat definitions
instead.
Cleaned the source a bit.

Some slight other changes.

respective setter/getter methods to the KPartition class.
If a partition is mounted, the field will contain the cookie the
FS's mount() hook passed back to the VFS. This way the FS has
access to its internal data structures. We need the cooperation
of the VFS to get the cookie.

bootfs cannot handle the path depth/length required to be a useful module

Added a comment about how to traverse the module path to find a given module -
could well be that we got that wrong (too loose, it will work perfectly, though,
just slower than it could be).

"sudden unmounts" (as far as that can work). This replaces the weak
find_mount() call used at several places in the fs index functions.

Reordered the syscalls a bit (in functional groups), not completely, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4354 a95241bf-73f2-0310-859d-f6bbb57e9c96
The lock_memory()/unlock_memory() functions cannot be implemented right

kernel_os_arch_x86.o file that is genereated by libroot.
Removed duplicate implementations from this file.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4337 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made the "name" argument const for create_area_etc() and vm_map_physical_memory().
Moved some common conversion code (BeOS to NewOS VM constants) to separate
functions to clean them up a bit.
create_area() now automatically sets LOCK_KERNEL if the area is to be created
in kernel space (as I would guess BeOS does, too).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4331 a95241bf-73f2-0310-859d-f6bbb57e9c96

delete_area() now only allows to delete areas you have created
yourself before from userland, again.
The kernel's delete_area() still allows everything, though.

delete. Added a comment how the security should be improved by adding another
restriction.
Also mentioned that it's probably a bad idea that vm_delete_region() will
not wait until the region has been freed, but just "mark" it as to be freed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4319 a95241bf-73f2-0310-859d-f6bbb57e9c96
that will call the internal vm_*() calls. This will make it easier to just
drop in another VM.
Also (partially - Ingo was faster) introduced the new syscall naming scheme
_kern_ & _user_ prefixes to them into the system namespace, and no longer
clobber the application namespace.
Removed the now unused user_vm_create_anonymous_region() call.

to work at all: recurse_directory() always returned failure, no matter what opendir()
returned (one semicolon too much), create_module() allocated only 4 bytes for
the module - sizeof(module) referred to the variable, not the structure name...
(the unfortunate consequences of the naming scheme I otherwise like very much -
it "just" took me 3 hours to hunt both bugs down).
Added some TRACE() and ASSERT()s.
Added a new debugger command "modules".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4300 a95241bf-73f2-0310-859d-f6bbb57e9c96

The CBUF_FLAG_CHAIN_TAIL is now set for the lastBuffer instead of buffer.
Removed some superfluous lines in cbuf_get_ptr(), and cbuf_ones_cksum16().
Fixed the buffer->length calculation in cbuf_truncate_tail() and added some
comments about the correctness of the code - should be investigated and fixed.

to the module interfaces. So the disk system will be informed, when a
shadow partition has changed and it is allowed to do necessary
adjustions (e.g. adjusting the cookie, the parameters, or on
partitioning system initialization even creating special child
partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
partitioning system can report at which index the new child shall be
inserted.

PrettyName() of the responsible disk system.
* Added change counter support and changes tracking.
* Added UninitializeContents().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4042 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed the disk_system_id parameter where superfluous.
* Got rid of the `child' variants of the _kern_{supports,validate}_*()
syscalls for moving and resizing. Reimplemented the real ones to do the
the right thing, i.e. they check all concerned disk systems now.
* Added _kern_supports_setting[_content]_parameters().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4020 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed handling of the deletion (removal) of shadow partitions. Formerly
the shadow partition corresponding to the disk device wasn't removed
properly.
* Added a shadow_id field to the user_partition_data structure which
