to userland applications. A userland server (probably the registrar) will
register as the server responsible for delivering the messages. The
messages are passed to it via shared memory.
The advantage over sending the messages directly will be, that they won't
need to be dropped, if the receiver port is temporarily full.
Currently only the kernel side is implemented. Completely untested yet.

footprint implementation. Can be used for kernel->userland messaging.

rules for userland applications/libraries anymore...

cache_io() should now finally work correctly in all cases.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10906 a95241bf-73f2-0310-859d-f6bbb57e9c96
this file still does the right thing as suggested by Michael Pfeiffer.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10882 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added short description to find_reserved_area() as that name is not that good.
vm_reserve_address_range() now doesn't do anything if the requested size
of the reservation is zero.

and thus clobbering all sorts of memory (oh my god).
The problems with ResourceFile now seems to be gone.

up for the first time, it will try to load all drivers that may export
devices there. Those devices will currently stay loaded, though - this
will only be changed when load_kernel_add_on() is able to cache add-ons.
Renamed pnp_devfs_probe() to pnp_devfs_register_device().
Fixed debug output for devfs_create().

con_init() now takes care of the initialization of its currently built-in
console drivers itself.

because it has some advantages over a relocatable kernel.
Removed libbus.a as it's no longer needed.
kernel.so now depends on kernel, so that both files are updated at once.

Comment cleanup for consistency.
Renamed remaining "omode" variables to openMode.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10831 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added kernel private calls load_module() and unload_module() that can be used to
load/unload modules by path.
load_module_image() now only mentions when it couldn't load a module when tracing
is enabled (because the device manager uses it to determine if an add-on is a
module or an old-style driver).

included fs_info.c).
Minor comment cleanup to make their appearance consistent throughout
the kernel.

check for B_TIMED_OUT and B_WOULD_BLOCK, but it got through with other
errors.
Removed special error check for "known" error codes from port_buffer_size_etc(),
read_port_etc() and write_port_etc() - they no longer print out a warning in
that case.

debug output - to activate it, you now have to enable it in the kernel
settings file ("bochs_debug_output true").
Reimplemented the serial output so that it's flexible towards the base
port at run time.
Implemented support for kernel settings "serial_debug_port" (which can
now also be an index in the BIOS provided serial ports list), and
"serial_debug_speed".
That also means that you can finally use the same kernel executable
under BeOS Bochs and on a real system without any restrictions.

Also added a ToDo comment about a required mutex API change in order to
be able to return a status that indicates failure.

It will now load all settings in the kernel driver settings directory
and pass them over to the kernel (unparsed).
Additionally, it allows other parts of the boot loader to access
driver_settings just like in the kernel.
Moved the switch to the logo in the boot loader much further to the end
of the boot loader's life cycle. This is done so that the boot loader
can directly use the video mode as configured in Haiku, without a jumping
logo. Since the delay will be noticeable on a real system, we might want
to introduce a second different boot logo, though. We'll see.
stdio.cpp now also exports errno (and _errnop). Might be changed to a
different approach later as well (it's now done this way so that strtol.o
can be taken over unchanged from libroot.so).

When compiled in the kernel, driver settings are cached and may be used
without disk access at all.
Added some comments.

Also fixed a potential bug when reading across page bounds (pageOffset
might not have been properly reset).
Added some more comments and ToDo items.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10627 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added generic syscall to control the cache. Right now, only setting/removing
cache modules is implemented.

not load the boot modules again).
The path of preloaded images is now hacked together so that the module
image hash contains the correct path in case the images get replaced
while being used.

standard mechanism - recurse_directory() is now only used if SUPPORT_BOOTFS
is defined and vfs_get_module_path() failed.
Added standard system kernel add-ons directory to the search path list.
Renamed USER_MODULE_PATHS to FIRST_USER_MODULE_PATH as that's what it is.

path, since it didn't take into account that vnode_path_to_vnode() may
actually change the provided buffer.
Also fixed a potential buffer overrun in that function (bufferSize was
not correctly changed), and added a comment about a previously undocumented
property of vnode_path_to_vnode() that vfs_get_module_path() relies on.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10598 a95241bf-73f2-0310-859d-f6bbb57e9c96

Also introduced a whole range of reserved syscall functions in case we want
to add some more.

to add debugging or temporary kernel calls without messing up the syscall
table (the syscall numbers will stay constant).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10452 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed find_reserved_region() to find_reserved_area(), and
find_and_insert_region_slot() to find_and_insert_area_slot().

It's a bit hackish due to the iospace area, and it also might not work
perfectly in all situations, but it does fulfill the current needs.

cache_node_{opened|closed}() now correctly get the file_cache_ref from a vm_cache_ref.
Implemented cache_prefetch(): for now, it always prefetches the first 64 kB from the file.
Renamed read_from_cache() to read_into_cache().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10438 a95241bf-73f2-0310-859d-f6bbb57e9c96
different types to vnodes.
Renamed vfs_get_vnode() to vfs_lookup_vnode() as it doesn't grab a ref to the node.
Added new vfs_get_vnode() that actually grabs such a ref.
vfs_get_vnode_cache() now fills a vm_cache_ref instead of a void pointer.
Replaced SYS_MAX_NAME_LEN constants with the B_FILE_NAME_LENGTH that should have
been used there.
vnode::cache should have been a vm_cache_ref and is now.
