the writembr utility (I was just too lazy to make it build right now).

If get_nth_partition/session_info() returns with anything else than a
B_ENTRY_NOT_FOUND, an error message is printed out.
The device name can now be specified on the command line, added shortcuts
to identify a particular device, i.e. "cd-1-slave" or "slave1-cd" or
"1-atapi-slave" would be expanded to /dev/disk/ide/atapi/1/slave/0/raw.

Also fixed an almost bug that only catched B_BAD_TEAM_ID error codes from
get_team_info() (bad style).
Made it a bit more style guide compliant.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2488 a95241bf-73f2-0310-859d-f6bbb57e9c96
there is no libbe.so yet).
Doesn't even query the port; just causes send_notification() in the kernel
to be called which will print out some info.
Added to the build.

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
Moved definition of "struct io_context" from fd.h to vfs.h.
Introduced new fs/ directory; some cleanups to come.
Added node monitor syscalls.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2479 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug that asked ld to discard the .dtors section.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2450 a95241bf-73f2-0310-859d-f6bbb57e9c96
libglue(2).so are now using the new startup code.
libroot.so now statically links against libgcc.a for now (to be able to load
BeOS executables).
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2449 a95241bf-73f2-0310-859d-f6bbb57e9c96
This has almost the same layout as in BeOS - the only difference is crt0.o which
is what is usually provided by crti.o/crtbegin.o/crtend.o/crtn.o. When we want to
move to GCC's crtbegin/end code, we have to introduce crti.o and crtn.o. This is
required because the crtbegin/end stuff assumes to be inserted between a function
start (crti.o) and a function end (crtn.o) - which can only be achieved with assembly,
and is therefore platform dependent.
start_dyn.c is used for executables and calls main() (among other).
init_term_dyn.c functions are called from the .init/.fini sections and search
for B_INIT/TERM_BEFORE/AFTER_FUNCTION_NAME, and execute them if they are present.
Both use BeOS compatible call scheme but add parameters to the end.
lib0.c is no longer needed, because init_term.c/crt0.c replace its functionality.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2448 a95241bf-73f2-0310-859d-f6bbb57e9c96
Note, the _start() function is now called with 4 parameters, because BeOS
requires the first three (the fourth isn't used in BeOS executables).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2447 a95241bf-73f2-0310-859d-f6bbb57e9c96
doesn't export it), initialization has also moved to initialize_before().
Added BeOS compatibility stubs to allow execution of BeOS native apps - added
comments to every function; some of them might be removed later on again.
Also moved "environ" to posix/stdlib/env.c for the same reason.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2446 a95241bf-73f2-0310-859d-f6bbb57e9c96
instead of "INIT_BEFORE/AFTER_CTORS".
Uses the new runtime linker exports.
Note, this is not yet BeOS compatible (will need to have init/fini sections)!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2441 a95241bf-73f2-0310-859d-f6bbb57e9c96
INIT_BEFORE_CTORS() is now called initialize_before() to be compatible
with BeOS start_dyn.o.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2438 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a simple locking strategy to the loader (didn't do any locking before),
it now uses a global recursive lock for the exported API.
Implemented all needed functionality for the BeOS image API.
Now registers images with the kernel.
Added several ToDo items.
Cleanups, and possibly more I've forgotten about.
(hope this works since the local diff does not?!)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2436 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now more dynmodule_id; it now uses the image_id directly.
Updated for the other changes to the functions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2433 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
to "struct uspace_program_args", prog_name & prog_path to program_name and
program_path.
Moved the MAGIC_APPNAME to a BeOS compatible MAGIG_APP_NAME from rld_priv.h
to this place.
Removed the dlxxx() exports in the rld_export structure - instead, they will
be implemented using the basic runtime linker API which is a slightly extended
version of the standard BeOS calls (load_add_on() has a "flags" paramater to
allow implementation of dlopen()).
Completed the export API to be able to completely support the BeOS API.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2420 a95241bf-73f2-0310-859d-f6bbb57e9c96
queries, to let the BPlusTree::Find() method search for it (there can't be
any keys in the tree with length 0).
That means that the query 'META:url=""' will now return all files where the
attribute "META:url" is present but empty.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2401 a95241bf-73f2-0310-859d-f6bbb57e9c96
in the same directory - in this case, we will return B_OK (as nothing has
to be done to fulfill the request), instead of B_BAD_VALUE which would
be thrown later in the process.

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
(the same change has already been done in support/TLS.h).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2392 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
Renamed i386_set_kstack() to i386_set_tss_and_kstack(), because that's what
it does.
Added a new function arch_thread_init_tls() which must be called after
having allocated the TLS area.
Renamed arch_thread_initialize_kthread_stack() to arch_thread_init_kthread_stack()
to be more consistent.
Changed the parameters for arch_thread_enter_uspace() - it now gets a pointer
to the thread structure and takes the user stack pointer from there (which
might also be architectural different).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2379 a95241bf-73f2-0310-859d-f6bbb57e9c96
BeOS values commented beneath it.
For now MAIN_THREAD_STACK_SIZE is the same as STACK_SIZE.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2377 a95241bf-73f2-0310-859d-f6bbb57e9c96
We now have a separate errnop() for the kernel, which just references
a field in the thread structure.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2376 a95241bf-73f2-0310-859d-f6bbb57e9c96
in a header if it was included from assembler or not (if anybody knows a better
way how to solve this, feel free to speak, I haven't found anything :).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2367 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
Moved the tss_descriptor structure to descriptor.h, updated it to be a
segment_descriptor structure, and provided inlines for set_tss_descriptor(),
set_segment_descriptor(), set_segment_descriptor_base(), and
clear_segment_descriptor().
Also added defines for the different privilege levels and descriptor types.
Removed the unusused and incorrect TSS definition, introduced new
TSS_BASE_SEGMENT and TLS_BASE_SEGMENT macros.
Removed include of arch/cpu.h in arch_cpu.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2360 a95241bf-73f2-0310-859d-f6bbb57e9c96
returned a (void *) instead of a (void **)).
Added TLS_MAX_KEYS macro, and a comment.
Cleanup.

some structure definitions (to outline some basic ideas), and the symbols
exported to userland.

The correctness of max_number_of_levels is now checked in Find().
Added a class NodeChecker which checks the integrity of the specified node
when the object is destructed (via new method bplustree_node::CheckIntegrity());
now used in Remove() and Insert().
