Renamed variables to be much nicer.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3148 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added math-arch PPC files - general status: working but not optimized.

too.
Everything should work except for: pthread_mutexattr_(set|get)prioceiling/

it a high priority.

implementing a more efficient on_exit_thread().
Note, this extra parameter is currently only used for user space code,

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

normally, I wouldn't checkin a file with cosmetic changes only
however, Marcus just made a change on this file earlier today,

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2853 a95241bf-73f2-0310-859d-f6bbb57e9c96

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.

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

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.

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.

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).

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
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.

Some other cleanups.

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
We now have a separate errnop() for the kernel, which just references
a field in the thread structure.

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.

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.

or while a section of code is running with interrupts disabled (with the

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.

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.
