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.

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

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

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.

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

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.

Also fixed a minor bug in dec_vnode_ref_count(): the unusued vnode counter
was not decremented again when one vnode was removed.

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).

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

(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).

Also implemented a get_bios32_service() function which you can use to get

Ceccherini for the hint.

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.

For now, it always returns B_ENTRY_NOT_FOUND - since the boot loader

booting into Haiku.

_user_create_area() and _user_clone_area() now inherit the read/write protection

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.

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.

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

Some cleanup.

As a quick hack, they no longer disable interrupts, so that the env memory

Removed definition of STD_INSPIRED: this not only fixes some warnings, it

as the size of the arguments is known before.

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.

- 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.
