Axel Dörfler 822ea83244 list_add_link_to_tail() didn't work correctly.
Applied fixes by notion: removed two redundant if-statements, replaced
(link *)list with &list->link.

Axel Dörfler 457f7be6f9 Now uses the new list primitive instead of its own implementation (for linking
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.

Axel Dörfler a7d654ad0a Added almost complete node monitor implementation - support for watching mounts/
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.

Axel Dörfler c8019cad42 Added support for the image queue in the team structure.
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.

Axel Dörfler 4fff689f48 Some minor updates:
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().

2003-01-08 09:27:55 +00:00
Axel Dörfler 20726b7fb1 _create_thread() now correctly allocates the stack with REGION_ADDR_EXACT_ADDRESS
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.

Axel Dörfler 59cbb92fdf team_create_team2() now also allocates a region for TLS in the primary stack
area. It now also calls arch_thread_init_tls(). Cleaned it up to make it more
readable, added some comments.
Some other cleanups.

Axel Dörfler 2a6fbb7f88 Removed some hard-coded values with definitions (mostly USER_x_SEG in arch_x86.S,
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.

2003-01-07 09:33:30 +00:00
Axel Dörfler 19321ae5a8 Temporarily removed arch_selector.c from the build - it's currently not used
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.

Axel Dörfler 1d661e3285 Just slightly changed a comment; there was more, but I removed that, and
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.

Axel Dörfler fb101ff170 Completely rewritten the module iterator code. Fixed many bugs in that
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.

2002-11-30 02:36:31 +00:00
beveloper c0d31b20ab Fixed the detection of page faults that happen while interrupts were
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.

Axel Dörfler 750a82c5d3 Added new debug output macros (TRACE()).
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.

Axel Dörfler b9b1c1c4f5 Almost completely rewritten module.c. Locking now works correctly, memory
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.
