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.

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.

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).

Minor comment cleanup to make their appearance consistent throughout
the kernel.

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 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.

this during runtime to add and remove specific syscalls. You can also use this
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10445 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10431 a95241bf-73f2-0310-859d-f6bbb57e9c96
Later on (but before R1), we should find a better balance between what
the FS has to implement, and what the kernel delivers to them.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10399 a95241bf-73f2-0310-859d-f6bbb57e9c96
fd_and_path_to_vnode() now accepts NULL as path argument.
Added some more debug output and comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10368 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also fixed a minor bug in dec_vnode_ref_count(): the unusued vnode counter
was not decremented again when one vnode was removed.

more than once, the size requested was only correct for the first time.
Added preliminary support for cache modules.

actually fills a cpuid_info structure. Renamed cpuid() to get_current_cpuid().
Added syscall _user_get_cpuid().
Added a lot of other vendor brand strings. The cpu_type and cpu_revision
fields should now be correctly set.
get_cpuid() now returns B_BAD_VALUE if the cpuNum parameter is out of bounds
(ie. higher than the number of available CPUs in the system).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10321 a95241bf-73f2-0310-859d-f6bbb57e9c96
limit, but this is not yet enforced. Added getter functions.
team_init() now returns a status_t.
System info stuff is now globally initialized in main().
get_system_info() now also reports the number of used pages, and calls the
architecture dependent function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10315 a95241bf-73f2-0310-859d-f6bbb57e9c96
added get_cpuid() function (does not respect the cpu parameter yet).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10314 a95241bf-73f2-0310-859d-f6bbb57e9c96
and no longer relies on put_vnode() for the root node. This will also call
the FS release/remove vnode calls. Extended comments.
Added "flags" parameter to unmount.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10289 a95241bf-73f2-0310-859d-f6bbb57e9c96
(free_vnode()). Upon freeing, the file cache is now only written back if the
file is not deleted.
dec_vnode_ref_count() no longer frees vnodes that are not going to be deleted.
Instead, it will add them to an unused vnode list, so that they can be freed
if needed (currently only 512 unused vnodes will be kept around). This should
speed up the whole thing, and makes the file cache much more useful, as it's
no longer dumped after the file is closed.
fs_unmount() is not yet respecting this (ie. it doesn't free those nodes as
it should).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10287 a95241bf-73f2-0310-859d-f6bbb57e9c96

Also implemented a get_bios32_service() function which you can use to get
access to that service (ie. for use by the PCI bus manager).

done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10285 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added user_shutdown user control

Ceccherini for the hint.
The first port ID is now 1 and not 0 anymore.
Added a first free slot hint to speed up port creation.
Added more debug output when tracing is enabled.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10260 a95241bf-73f2-0310-859d-f6bbb57e9c96
BeOS supports this as well, at least it's not documented in the BeBook
(but it's useful anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10259 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed _user_set_tzspecs() to _user_set_timezone().
Renamed sTzFilename to sTimezoneFilename.
Moved rtc_print() into rtc_debug().
Fixed changing system_time_offset; since this is a shared 64 bit value,
we have to use atomic calls when we change it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10253 a95241bf-73f2-0310-859d-f6bbb57e9c96
and only the syscall is exported.
For now, it always returns B_ENTRY_NOT_FOUND - since the boot loader
does not have support for driver settings yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10237 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added _user_shutdown() and made it available as syscall.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10233 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented F_DUPFD support for fcntl() - we no longer see any redirection errors when
booting into Haiku.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10221 a95241bf-73f2-0310-859d-f6bbb57e9c96
_user_create_area() and _user_clone_area() now inherit the read/write protection
for the kernel, too - before, it was always mapped read/write in the kernel,
but there is no reason to do that.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10214 a95241bf-73f2-0310-859d-f6bbb57e9c96
an off_t as size argument.
Implemented new function vm_cache_write_modified() which will write all
dirty pages of this cache back to disk (using the new vm_page_write_modified()
function).
Fixed warnings when compiled with debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10205 a95241bf-73f2-0310-859d-f6bbb57e9c96
pages in a cache back using the store's write method. Doesn't optimize
disk access yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10204 a95241bf-73f2-0310-859d-f6bbb57e9c96
While we can tolerate the device driver to ignore the bytes argument when we
read from the device, we cannot do this for writes - now the code actually
takes this into account. Also added a comment about what to do when our own
driver is fixed :)
Implemented file_cache_sync().
file_cache_set_size() now uses vm_cache::virtual_size instead of the now
removed vnode_store::size. Also, it now resizes the vm_cache as well, so
that any no longer used pages are freed.
write_to_cache() now puts all pages in the modified list, so that they
can be written back easily.
Improved debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10203 a95241bf-73f2-0310-859d-f6bbb57e9c96
vm_cache::virtual_size is now used by the file cache code.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10202 a95241bf-73f2-0310-859d-f6bbb57e9c96
dec_vnode_ref_count() now deletes the cache *after* calling the file system's
remove/release vnode function. Also, it will now write back any pending
changes in that cache before removing it.
Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10201 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now, it will only notify the read requests do gather the data.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10198 a95241bf-73f2-0310-859d-f6bbb57e9c96
move code from use of boot_time to use of system_time_offset

stuff belongs to userland), they are completely broken, too.
As a quick hack, they no longer disable interrupts, so that the env memory

Please don't fix this, but remove those functions from the kernel.
