limit, but this is not yet enforced. Added getter functions.
team_init() now returns a status_t.
System info stuff is now globally initialized in main().
get_system_info() now also reports the number of used pages, and calls the
architecture dependent function.

BeOS supports this as well, at least it's not documented in the BeBook
(but it's useful anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10259 a95241bf-73f2-0310-859d-f6bbb57e9c96
stuff belongs to userland), they are completely broken, too.
As a quick hack, they no longer disable interrupts, so that the env memory
can be accessed almost safely (in case its valid memory at all).
Please don't fix this, but remove those functions from the kernel.

Fixed a bug in the team thread start: it did not set sizeLeft correctly
before copying the arguments - shouldn't have had any consequences, though,
as the size of the arguments is known before.
Added a comment explaining the current layout of the main thread stack area.
Now makes use of B_STACK_AREA and B_KERNEL_STACK_AREA.
fill_thread_info() did not correctly set thread_info::stack_end.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10016 a95241bf-73f2-0310-859d-f6bbb57e9c96
in the wrong direction for some time now, corrupting the argument area (user
apps would crash).
B_SYSTEM_TEAM is now reserved, so that no team can be created there.
Fixed some warnings when debug output is enabled.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9719 a95241bf-73f2-0310-859d-f6bbb57e9c96
team and process group IDs as well.
Added a ToDo item that process groups do only work well as long as
their group leader is still active.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9394 a95241bf-73f2-0310-859d-f6bbb57e9c96
always copies the arguments and environment arrays.
No need for the "owns_arrays" in team_arg anymore - it now always owns
them.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9363 a95241bf-73f2-0310-859d-f6bbb57e9c96
The path name is now always taken from the provided argument list (except for
_user_exec() which now replaces args[0] with the path argument).
The team_arg structure know nows if it must delete its arguments or not - this
also fixes a memory leak in case team_create_team() failed when invoked from
userland.
load_image() is now also exported for the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9360 a95241bf-73f2-0310-859d-f6bbb57e9c96
process ID (in the current session).
get_death_entry() could call free() with interrupts disabled; now follows
the same mechanism as chosen with the groups (ie. it returns a pointer
to a death_entry to be freed by the calling function).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9354 a95241bf-73f2-0310-859d-f6bbb57e9c96
- we now have a working process group/session model. Implemented related syscalls
and the kernel backend, some POSIX process functions are now available in the
kernel as well.
- dying teams now monitor their exitus by leaving death_entry structures in
their parent team.
- Implemented wait_for_child() for pid == -1 and pid > 0; IOW waiting for process
groups is missing yet. Hasn't yet been tested intensively.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9350 a95241bf-73f2-0310-859d-f6bbb57e9c96
team's address space - for internal use, anyway.
Added a ToDo: item to exec_team() to remind me of alarms and signals.
Started implementing fork_team() based on team_create_team() - it's not
completed (or even works), though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9279 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9255 a95241bf-73f2-0310-859d-f6bbb57e9c96
Should be tested and verified more intensively, though.
Moved the creation, initialization, and deletion of the team_arg structure out of
team_create_team(); it's now also used by exec_team().
Renamed kfree_strings_array() to free_strings_array().
Renamed the fields of the team_arg structure to be more in sync with the names used
at other places.
Fixed the routine that copied the environment/arguments into the userland space.
Improved and fixed the user_copy_strings_array() function.

potential bug if MAIN_STACK_SIZE and STACK_SIZE would have been different.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9190 a95241bf-73f2-0310-859d-f6bbb57e9c96
syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8704 a95241bf-73f2-0310-859d-f6bbb57e9c96
stack - it just fails now (since create_area() currently panics when it
fails, this is a cosmetic change anyway :-)).
Now correctly cleans up in case elf_load_user_image() fails.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7883 a95241bf-73f2-0310-859d-f6bbb57e9c96
The stack of the main thread is now called "{team name}_main_stack" instead
of primary stack.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7863 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Fixed missign file system unload.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7527 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
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
Added our license to the updated source files.
Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6672 a95241bf-73f2-0310-859d-f6bbb57e9c96
implementing a more efficient on_exit_thread().
Note, this extra parameter is currently only used for user space code,
not yet in the kernel; thus on_exit_thread() is not available in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3075 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed team_wait_on_team() to wait_for_team() (more BeOS-alike).
Adapted to other changes (new thread functions).
Cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2576 a95241bf-73f2-0310-859d-f6bbb57e9c96
Adapted because of changing structure names (struct uspace_program_args).
Added comments, fill_team_info() now sets the team_info.image_count correctly.
Some cleanups and style changes.
