stuff belongs to userland), they are completely broken, too.
As a quick hack, they no longer disable interrupts, so that the env memory
can be accessed almost safely (in case its valid memory at all).
Please don't fix this, but remove those functions from the kernel.

Improved "thread" debug output to have all data values at the same column.

were messed up because of that, most shell pipe access didn't actually work
(thinks like "cat x | grep y", or "a=`uname -m`) - they now do.
Added more debug output.

to properly shutdown from the kernel debugger.

- Ported over BFS to the new cache API
- Inode no longer inherits from CachedBlock, and therefore, no longer
keeps the whole inode block in memory. It now has a copy of the bfs_inode
structure in memory instead. This has a number of advantages but also some
disadvantages, so it might be reverted later, even if it's unlikely.
- Added a NodeGetter class that can be used whenever the real block needs
to be accessed (ie. for attributes)
- Changed *transaction to &transaction where possible
- Removed support for KEEP_WRONG_DIRENT_RECLEN
- Removed support for uncached file access since that's no longer needed
- Fixed some endian issues in bfs_write_stat()
- Removed the install BFS rules, since they don't make any sense anymore
(unless you are running Haiku ;-))
Note, logged streams are not supported anymore right now. Also, the
transaction code is pretty simple and slow - it will be improved later
on. Attribute code is pretty much untested in the new environment.

R5 compatible version still has this support).
Added a missing const to block_run::IsZero().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10049 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added API for sub transactions (not yet implemented).
Added file_cache_sync() function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10047 a95241bf-73f2-0310-859d-f6bbb57e9c96
not everything is in this one file.
Removed definition of STD_INSPIRED: this not only fixes some warnings, it
also removes functions that are not exported under BeOS, and there is no
reason to change that.
Added weak export of timelocal() in case STD_INSPIRED is not defined in
localtime.c.

Fixed a bug in the team thread start: it did not set sizeLeft correctly
before copying the arguments - shouldn't have had any consequences, though,
as the size of the arguments is known before.
Added a comment explaining the current layout of the main thread stack area.
Now makes use of B_STACK_AREA and B_KERNEL_STACK_AREA.
fill_thread_info() did not correctly set thread_info::stack_end.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10016 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in arch_init_tls() that did not support different stack sizes
(ie. didn't use the thread::user_stack_size variable).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10015 a95241bf-73f2-0310-859d-f6bbb57e9c96
B_BAD_HANDLER, vm_soft_fault() will just continue as if there is no fault()
function.
There is now support for the B_STACK_AREA and B_KERNEL_STACK_AREA protection
values: if the former is used, or the latter in combination with DEBUG_KERNEL_STACKS,
a number of guard pages is inserted at the bottom of the stack (depending on
the STACK_GROWS_DOWNWARDS/UPWARDS arch config).
In addition, user stacks are no longer committed completely, ie. they don't
reserve memory for their whole size, only as much as is needed. That may
result in applications crashing when they need a lot of stack and there is
no memory left. Before this change, you could not even run that application.
Since BeOS has a 16 MB stack for the main thread, you could only run about
2 applications with 64 MB before.
Due to these changes, we've now switched to the standard BeOS stack sizes.
Some minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10014 a95241bf-73f2-0310-859d-f6bbb57e9c96
MAIN_THREAD_STACK_SIZE to USER_MAIN_THREAD_STACK_SIZE.
Added support for stack overflow debugging: in userspace, the lower (on x86)
4 pages will be used to detect stack overflows. It's disabled for kernel
stacks by default.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10013 a95241bf-73f2-0310-859d-f6bbb57e9c96
- renamed setup_rtc_boottime() to __init_time()
- __init_time() is now initialized at libroot.so startup
- introduced new __arch_init_time() that does the arch dependent stuff,
for now it just sets the system_time() conversion factor (that's the
part that will change later on)
- os/time.c now keeps a pointer to the real_time_data around, not only
to the boot time - maybe we'll it for other stuff as well later.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9995 a95241bf-73f2-0310-859d-f6bbb57e9c96
the x86 protection model to page level protection only. It's currently needed
for BeOS compatibility, though we might want to get rid of it later. Thanks
to Jerome for stombling into this :)
arch_vm_translation_map_init_post_sem() did not return a proper status.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9989 a95241bf-73f2-0310-859d-f6bbb57e9c96
Improved how it can be used, added a description at the top of the file, too.

offset to recognize the boot volume.
This should work well enough for now (as long as you don't have too many
disks in your system).

"Dumb" checksum/size recognition is not yet implemented (stores only the
size of the disk for now).

the boot partition, and calls platform_register_boot_device() for the
rest.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9961 a95241bf-73f2-0310-859d-f6bbb57e9c96
now fields that carry information about the boot disk and partition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9956 a95241bf-73f2-0310-859d-f6bbb57e9c96
added flags parameter (for example for B_MOUNT_READ_ONLY).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9939 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added user data pointer to cache_transaction notifier
- added functions block_cache_set_dirty(), and block_cache_make_writable()
- cache_transaction_next_block() let's you iterate over all blocks in the transaction
- instead of binding the block contents to the transaction (read-only checked
out blocks did only see the unchanged blocks until the transaction was closed)
the block now always shows the current data - even if the old way had some
advantages, it was terrible to use
- the blocks were not correctly added to the transaction
- improved debug output
- can check if the read-only blocks were changed accidently (compile time option)

we don't want to copy them over to the kernel heap, we just don't free
the kernel args if the debug symbols are enabled - and since there are
no driver settings yet in the kernel, this is always for now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9931 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved from mutexes to benaphores.
Removed partial write support of the old API.
remove_cached_device_blocks() will now actually free all remaining blocks.

to the arch independent section (pure laziness + I am not yet sure how this
will look like on other platforms).
Fixed the clone_area() command: B_CLONE_ADDRESS must not be used in the
same address space, because the area creation then can only fail.
Added an explanation on why the area is cloned at all.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9885 a95241bf-73f2-0310-859d-f6bbb57e9c96
we do not support mount() and unmount() anymore.
I've not removed that file in case we decide that we have to export those
functions for whatever reason.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9868 a95241bf-73f2-0310-859d-f6bbb57e9c96
The page_stats debugger command now understands queue names as well.
Some minor cleanup, improved error checking.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9861 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed vm_area::lock to vm_area::protection to be less confusing - wiring
is still called wiring, though (might be renamed to lock later, as that's
how BeOS calls it).
Renamed some global variables to match our naming scheme.

Renamed all static global variables to have the 's' prefix.
acquire_sem_etc() now fails if B_RELATIVE_TIMEOUT and B_ABSOLUTE_TIMEOUT
are both set.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9854 a95241bf-73f2-0310-859d-f6bbb57e9c96

B_RELATIVE_TIMEOUT at the same time.

is kernel only but writable now - should be cloned).

and the kernel.
create_area() can now only create kernel areas.
_user_create_area() now directly calls vm_create_anonymous_region().
Removed broken find_region_by_address() and find_region_by_name().
Removed vm_find_region_by_name().
Renamed the idle thread stack areas.
