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
Added TRACE_SMP and a TRACE() macro that is used instead of dprintf() directly.
Also fixed all warnings with TRACE_SMP set to 1.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2941 a95241bf-73f2-0310-859d-f6bbb57e9c96
changed the field order in a couple of structs back to their previous ordering
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2856 a95241bf-73f2-0310-859d-f6bbb57e9c96
normally, I wouldn't checkin a file with cosmetic changes only
however, Marcus just made a change on this file earlier today,
so the file would have to be rebuilt anyway -- might as well
make it pretty too!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2853 a95241bf-73f2-0310-859d-f6bbb57e9c96
but doesn't have to be read from disk for efficiency reasons.
Fixed a bug in get_vnode() in case of fs->get_vnode() returns an error of some
kind.
fs_mount() no longer hides the return code from the fs->mount() function anymore (for now).
Added some comments and ToDo items.
Changed some return error values to the B_xxx style (will probably need to define
some new error codes for OpenBeOS).
Changed some return types to status_t/void where appropriate.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2786 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed apic_read()/apic_write() to accept offsets not addresses as register
parameter.
Cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2605 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread code now properly traces time spent in user vs kernel mode. The code was
just plain broken before
http://www.newos.org/cgi-bin/perfbrowse.perl?@describe+1704
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2599 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a SIGNAL_TO_MASK() macro.
Removed the useless disable_interrupts() call in set_alarm().
More cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2584 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now directly exports (as is, most of) the kernel thread API.
Now has user_*() functions where needed.
Moved thread_set_priority() from scheduler.c to set_thread_priority().
Renamed thread_wait_on_thread() to wait_for_thread().
user_get_thread_info() now uses user_strlcpy() instead of user_strncpy().
Fixed the snooze() implementation - it now returns B_OK where appropriate. Now all snooze()
calls will call snooze_etc().
New private call spawn_kernel_thread_etc() to replace thread_create_kernel_thread_etc().
Moved some functions around.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2578 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in sigaction(): it would have crashed with act/oact == NULL (which
is perfectly legal).
Now directly exports the kernel API.
Now has user_*() calls where needed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2577 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
and don't have any functionality at this place.
Added new syscall for set_thread_priority().
Some other changes due to cleanup.
Fixed userland snooze() call.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2575 a95241bf-73f2-0310-859d-f6bbb57e9c96
have the scheduler_ prefix instead of thread_.
Moved thread_set_priority() back to thread.c where it belongs to.
Added new function to remove a thread from the run queue.
Renamed run_q to gRunQueue.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2572 a95241bf-73f2-0310-859d-f6bbb57e9c96
Actually never unlocked the daemon's lock (always called mutex_lock() instead
of mutex_unlock()...).

the vnodes of a mount structure).
Removed stubs for send_notification() and notify_listener() (they are now located
in message.c and node_monitor.c).
Added support for the node monitoring service.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2482 a95241bf-73f2-0310-859d-f6bbb57e9c96
unmounts is not yet implemented.
Added an empty implementation for send_notification() - the function that is
(or will be) able to send out BMessages from within the kernel; currently
just prints out what should be done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2481 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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2426 a95241bf-73f2-0310-859d-f6bbb57e9c96
arch_cpu: could have used the TLS_SIZE macro in one place, removed
a now unused variable, assignments to tss_loaded are now booleans.
thread.c: added the new fields to _dump_thread_info().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2393 a95241bf-73f2-0310-859d-f6bbb57e9c96
from the USER_STACK_REGION (until B_BASE_ADDRESS is available), made it much better
readable. It now grows from the lower USER_STACK_REGION up to the start of the main
thread's stack location.
Calls arch_thread_tls_init() and accounts for the TLS area in the stack region.
Added some comments, some cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2382 a95241bf-73f2-0310-859d-f6bbb57e9c96
area. It now also calls arch_thread_init_tls(). Cleaned it up to make it more
readable, added some comments.
Some other cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2381 a95241bf-73f2-0310-859d-f6bbb57e9c96
and TSS_BASE_SEGMENT in i386_set_tss_and_kstack() (thanks Daniel for pointing this
out)).
Added a arch_thread_init_tls() function which fills the reserved slots - the find_thread()
inline asm in OS.h is finally working.
Added some more comments, resolved the ToDo items from last time :-)
arch_thread_context_switch() now calls set_tls_context() at the correct location.
arch_thread_enter_uspace() now calls set_tls_context() as there is no context
switch in this case for the current thread after TLS has been set up, and it
now gets a pointer to the thread structure directly, and calculates the user
stack top itself, rather than the callee.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2380 a95241bf-73f2-0310-859d-f6bbb57e9c96
at all, and assumes a fixed and wrong number of preallocated GDT entries.
Implemented TLS: there is one GDT entry per CPU. If a context switch happens,
the FS register of the new thread is set to the matching GDT, and the GDT is
changed so that it points to the current thread's TLS storage area.
This area currently resides unsafely at the bottom of the user stack - for
some reason I could not figure out, it doesn't even work correctly most of
the time (it segfaults when accessing a slot via FS). I've added a ToDo item
explaining the situation - hopefully I have more ideas when I slept a bit more...
The GDT is now no longer static in arch_cpu.c and has been renamed from gdt to
gGDT. It's now also referenced in arch_thread.c, and it would make sense for
arch_selector.c to use it as well (instead of another local copy).
arch_cpu_init2() now uses the set_tss_descriptor() inline function and the
TSS_BASE_SEGMENT macro to set up the TSS section. It now also sets up the
TLS segment descriptors (as TSS, one entry per CPU).
Since I removed desc_table from the headers (the GDT is now a (segment_descriptor *)),
I added it locally to arch_int.c.
i386_enter_uspace() now don't set the FS register to 0x23 anymore, since it's
now already set correctly at the end of arch_thread_context_switch().
Some clean-ups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2366 a95241bf-73f2-0310-859d-f6bbb57e9c96
I was too lazy to revert that little change back, so that I would be able
to write this short paragraph explaining what I've done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2364 a95241bf-73f2-0310-859d-f6bbb57e9c96
some structure definitions (to outline some basic ideas), and the symbols
exported to userland.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2214 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some int -> cpu_state cleanup on the way, and implement the
B_KDEBUG_CONT and B_KDEBUG_QUIT features in our kernel debugger.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2173 a95241bf-73f2-0310-859d-f6bbb57e9c96
code and made it much simpler (it now just uses a stack of path names
instead of this complex doubly-linked module_iterator_dir list).
Now works together with the rest of the code without making any problems.
Added a module_test() function which iterates over all existing modules.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2149 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some cleanups, moved user_*() functions to the end of the file.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2144 a95241bf-73f2-0310-859d-f6bbb57e9c96

forbids/permits can be nested.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2141 a95241bf-73f2-0310-859d-f6bbb57e9c96
disabled. If a page fault happend while a interrupt handler is executed,
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2124 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2119 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now the d_reclen field of struct dirent is correctly calculated in all
file systems (read_dir() function).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2114 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2113 a95241bf-73f2-0310-859d-f6bbb57e9c96
and to have better performance on Hyper Threading systems. Should be
backward compatible with all x86 systems, according to Intel documentation.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2068 a95241bf-73f2-0310-859d-f6bbb57e9c96
some minor rearrangement (sys_xxx() calls now placed together)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1997 a95241bf-73f2-0310-859d-f6bbb57e9c96
output strings -- the old debug table is still there,
now renamed 'sigstr[]'
MAX_SIGNO replaces 32 in several spots
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1976 a95241bf-73f2-0310-859d-f6bbb57e9c96
to use the newly provided function for this.
module.c now also uses the initque() function, some minor cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1973 a95241bf-73f2-0310-859d-f6bbb57e9c96
yet, but the jam problem is gone and some bugs fixed.
We are now using merged objects to bind different functionality together,
which simplified the kernel Jamfile a lot.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1841 a95241bf-73f2-0310-859d-f6bbb57e9c96
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()
call.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1831 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented realloc().
Adapted all other sources, some minor cleanups in some files as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1773 a95241bf-73f2-0310-859d-f6bbb57e9c96
hash implementations in that file... we should really remove one of them.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1747 a95241bf-73f2-0310-859d-f6bbb57e9c96
Not yet tested.
Moved the CHECK_USER_ADDRESS() macro from vfs.c to kernel.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1746 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed module.c and int.c to use that one.
Some minor cleanups in module.c.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1744 a95241bf-73f2-0310-859d-f6bbb57e9c96
not available in BeOS, so there is no reason to add them).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1663 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented index syscall functions in VFS.
Added fs_index.c to the build.
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1555 a95241bf-73f2-0310-859d-f6bbb57e9c96
which is now used thorough the VFS code instead of user_strncpy().
fd.c: Replaced some return codes.
vfs.c: joined attr_dir_open(), and attr_dir_open_fd(), added sys_/user_
calls to access attributes, and attribute directory.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1455 a95241bf-73f2-0310-859d-f6bbb57e9c96
Included NewOS change 1656 (O_CLOEXEC support, and a bug fix in get_vnode()).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1431 a95241bf-73f2-0310-859d-f6bbb57e9c96
for a valid team id.
Added a comment about a race condition in set_sem_owner().
Some minor style changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1309 a95241bf-73f2-0310-859d-f6bbb57e9c96
variables now have the 'g' prefix).
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
if it has good reason to do so.
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1308 a95241bf-73f2-0310-859d-f6bbb57e9c96
vm_translation_map_create() checks if the kmalloc()'d page is aligned - maybe
we should just disable the USE_WALL setting if size is PAGE_SIZE for now...
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1264 a95241bf-73f2-0310-859d-f6bbb57e9c96
set to 1 (which it currently is).
I've only used it with bochs yet, and it lets it crash reliably in some
VFS code.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1261 a95241bf-73f2-0310-859d-f6bbb57e9c96
You need to enable BOCHS_INPUT_HACK and type inside the BeBochs window,
NOT inside the Terminal where the output is printed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1219 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1175 a95241bf-73f2-0310-859d-f6bbb57e9c96
or entry_ref names (paths are safe).
Implemented attr_remove(), and attr_rename().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1171 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1168 a95241bf-73f2-0310-859d-f6bbb57e9c96
in fs_interface.h.
Fixed many warnings due to the int/int32/status_t changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1137 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also kernel/module.h was hidden by os/drivers/module.h - fixed; kernel/module.h
is now called kmodule.h and only contains the module_init() function for the
kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1122 a95241bf-73f2-0310-859d-f6bbb57e9c96
Only implements access from within the kernel, not from the BIOS. Since
it requires malloc(), realloc(), open(), etc. in the kernel, you can't
currently link it, but it's added to the build anyway (it's just not
linked against the kernel).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1114 a95241bf-73f2-0310-859d-f6bbb57e9c96
another terrible bug that managed to exist this long and not clobber everything.
The io vector table was being created with an incorrect size, so all sorts of garbage was getting written to whomever was allocated after it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1112 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1014 a95241bf-73f2-0310-859d-f6bbb57e9c96
This change also introduces a lot of new warnings concerning printf format
anomalies. Please do NOT fix them. Currently, int32 (and also status_t)
is of type int, but it will be of type long (BeOS compatible) soon, and
these warnings will disasappear.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@973 a95241bf-73f2-0310-859d-f6bbb57e9c96
many kernel debugger commands to be removed accidently...
Added a message if you entered an unknown command.
Some cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@758 a95241bf-73f2-0310-859d-f6bbb57e9c96
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().
Implemented sys_access() and added it to the file system interface.
Removed the fs function interface from vfs.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@738 a95241bf-73f2-0310-859d-f6bbb57e9c96
getcwd().
Introduced new xyz(int fd, char *path, ...) style of functions for
sys_setcwd(), and sys_write_stat().
Added missing sys_fstat(). Removed duplicated prototypes in syscalls.h
Fixed some minor bugs.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@669 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in module.c that I caused due to changes in the VFS.
Added the sys_write_link() call.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@666 a95241bf-73f2-0310-859d-f6bbb57e9c96
rel type (111) when it tried to load the PCI bus manager - I've only removed
the crash, but I didn't dig any deeper yet.
Note, this only happens using bochs - on a real computer, the kernel runs
obviously without any problems.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@593 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a mode parameter to sys_create_symlink().
Added an open_mode field to struct file_descriptor.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@592 a95241bf-73f2-0310-859d-f6bbb57e9c96
