yet, though, and just return B_ERROR.
devfs_unpublish_partition() now also returns B_ERROR since it's not yet
implemented.
Refactored the device publishing code, so that implementing devfs_publish_file_device()
will become easy.

* Added resolve_mount_point_to_volume_root() which does what
resolve_volume_root_to_mount_point() did. IOW the latter one didn't
do what it advertised.
* Fixed dir_vnode_to_path(). Basically broken due to the broken
resolve_volume_root_to_mount_point(), but also compared potentially
unrelated vnode IDs (belonging to different volumes).
* Fixed get_dir_path_and_leaf(). It didn't deal correctly with paths
ending in '/' (including the root dir).
* fs_mount() does now accept a NULL fsName, getting the FS name from
the DDM in this case.
* fs_mount() now also supports mounting file images; it lets the DDM
create a file device for them.

done by (currently not existing) devfs functions.
* Overridden GetMediaStatus() and GetGeometry() to return useful data.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9627 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved the debug macros into the program flow, so that they don't look so
temporary :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9557 a95241bf-73f2-0310-859d-f6bbb57e9c96
* fs_mount() and fs_unmount() are now aware of partitions. A device to
be mounted is looked up by the DDM and the mount state and mount
cookie of the corresponding KPartition are updated accordingly.
Still missing is support for mounting files. Moreover the device path
needs to be normalized.
* Added RecursiveLockAutoLocker class to ease the `goto errN' pain a bit.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9555 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made GetMediaStatus() a bit more robust. If the ioctl fails (e.g. if it
is not implemented as in Thomas' drivers), it gets the device geometry
and does not fail, if the device is not removable.

to be able to have more than 1280x1024x8 resolutions. The best solution, however,
would be to map the graphics memory outside of the kernel space, anyway.

it switched to the logo mode afterwards).
Improved and broke the second call of platform_switch_to_logo() with a
different video mode: it now at least works when switching to a lower
resolution.

and that main2() cannot therefore just wait until interrupts become
enabled.
Now, the main2() thread is resumed after interrupts are turned on.
I am not yet sure if this is really necessary, but I have the feeling that it is.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9531 a95241bf-73f2-0310-859d-f6bbb57e9c96
Improved the threads list: despite looking much better, it now also prints
out the semaphore number a thread is waiting on.

Now disables serial output when the boot menu is shown.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9528 a95241bf-73f2-0310-859d-f6bbb57e9c96
When the debug boot option is set, or ENABLE_SERIAL defined on compile time,
the serial port 1 is activated.
It will also read the serial base port info from the BIOS data and use
that if any ports are reported (will fall back to 0x3f8 if not).
Right now, a fixed baud rate of 115200 and 8n1 is used.

Menu::Supermenu() now work.
Added function to find an item by label.
The boot volume menu now actually lets you choose a different boot volume.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9525 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added the new arch_dbg_con_early_boot_message() function.

change the flow of things, it now has its own buffer, and fills it with
interrupts disabled (everything comes at a price).
Now uses the safe vsnprintf() instead of vsprintf() which could crash
the kernel.

thread. That also allows kernel threads to use the FPU as well.
arch_thread_enter_uspace() no longer needs to initialize the FPU.
i386_stack_init() is now only called once, in arch_thread_init(), as
thought.

want it to find; therefore, we're now using get_next_loaded_module_name().
Added a temporary suffix to the FS DDM modules (disk_device/v1) - they
might get merged with the standard FS interface modules.

eventual user stack regions of the thread.
The registers are no longer jumping around depending on the length of their values.
Removed some unused or doubly included headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9479 a95241bf-73f2-0310-859d-f6bbb57e9c96
We now have a working periodic wall checker, enabled by USE_CHECKING_WALL.

list (but not the structure itself).
Now calls heap_init_post_thread(), heap_init_post_sem() was called ..._postsem() before.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9457 a95241bf-73f2-0310-859d-f6bbb57e9c96
arch_cpu.h no longer includes kernel.h, so we have to do this for the
ROUNDUP()/ROUNDOWN() macros.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9441 a95241bf-73f2-0310-859d-f6bbb57e9c96
they are called.
Fixed some return types (mostly from int to status_t).
Some minor other cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9440 a95241bf-73f2-0310-859d-f6bbb57e9c96
they are called.
Introduced a cpu_init_post_vm() that will now call arch_init_post_vm() instead
of letting main() doing it.
Fixed some return types (mostly from int to status_t).
Some minor other cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9439 a95241bf-73f2-0310-859d-f6bbb57e9c96
three code locations that didn't handle them properly (when iterating over all
areas).
That and the fact that unmap_and_free_physical_pages() is no longer broken now
leads to the boot region being unmapped and freed properly as intended before.
That revealed another bug: the boot loader region was disposed too early, we
need a few other components pick up boot loader resources first; it now happens
in vm_init_post_sem().
allocate_kernel_args() was also broken, and actually didn't try to allocate
kernel args areas, but tried to reallocate all the virtual allocated ranges
of the boot loader...
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9437 a95241bf-73f2-0310-859d-f6bbb57e9c96
boot loaders passed in memory completely wrong (for example, the premapped
graphics buffer could be mapped to the same region as some thread stacks,
just because the VM did not use its knowledge about that mapping): the boot
loader regions are now reserved so that they cannot be overwritten
with other regions anymore. The kernel_args arguments are now tracked, and
areas are created for them (they are not yet freed, though). arch_vm_init_end()
must now call the new vm_free_unused_boot_loader_range() to free any remaining
parts of the memory not yet mapped in by any areas.
Renamed a lot of init functions (ie. postsem to post_sem, init2 to post_area),
also updated because of the vm_translation_map*() arch_vm_translation_map*() move.
B_ALREADY_WIRED can now only be used during kernel startup (it's a private flag).
Replaced PAGE_SIZE with B_PAGE_SIZE.
Some minor cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9429 a95241bf-73f2-0310-859d-f6bbb57e9c96
correctly by calling arch_vm_translation_map_init_kernel_map_post_sem().
dump_aspace() now behaves like all debugging functions should behave: it
now accepts decimal numbers as well as hexadecimal numbers as IDs.
vm_translation_map_create() was renamed to arch_translation_map_init_map().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9427 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved some functions around, so that the public functions come last.
Renamed the internal vm_translation_map_quick_query() to early_query(),
renamed vm_translation_map_quick_map() to arch_vm_translation_map_early_map().
Removed the _module part of the initialization functions.
Added a function that completes the initialization of the kernel map (it
creates the map's lock, which was just not done before).
arch_vm_translation_map_init_map() will now fail with an appropriate
error code if the map's lock couldn't be created for anything that
is not the kernel map.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9426 a95241bf-73f2-0310-859d-f6bbb57e9c96
loader preallocated, arch_vm_init_end() (formerly called _endvm())
now calls the new vm_free_unused_boot_loader_range() with the correct
parameters.
Moved the creation of the DMA area from 0-0xa0000 into arch_vm_init_post_area().
Changed return types to status_t rather than just having "int" stand
for a status code.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9425 a95241bf-73f2-0310-859d-f6bbb57e9c96
Most importantly, it now always uses map_physical_memory(), and no longer
relies on eventually mapped data by the boot loader (that the VM didn't
know about).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9418 a95241bf-73f2-0310-859d-f6bbb57e9c96
Exports the new insert_address_range() function as declared in boot/addr_range.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9416 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a kMaxKernelSize constant to be able to change that limit a bit
easier.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9415 a95241bf-73f2-0310-859d-f6bbb57e9c96
USE_WALL feature can now be used.
Started implementing a USE_CHECKING_WALLS feature, that has a kernel
daemon running that periodically checks the walls of *all* memory
allocations - does not work yet (because of some initialization order
problems).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9396 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
ignored completely (so that zero and below become valid).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9393 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now uses waitpid() instead of wait_for_thread() - and surprise, it doesn't
work yet :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9372 a95241bf-73f2-0310-859d-f6bbb57e9c96
no longer pop %fs from the iframe in that case, too.
When we restore a custom stack, however, we'll now pop %fs from the iframe
as such strange threads may even do their own business with it.
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9369 a95241bf-73f2-0310-859d-f6bbb57e9c96
We also should disable interrupts in arch_restore_fork_frame().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9368 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
Switched to load_image() instad of using the old team_create_team() to start "init".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9361 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
Enhanced exec_test.c to use some process functions as well.
Switched to load_image() instead of using the old _kern_create_team() syscall.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9359 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
the specified process group (by passing in a negative pid, as in BeOS).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9351 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
may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
(the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
Removed release_threads variable in release_sem_etc(), as it was useless.
