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().

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.

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.

Minor cleanup.

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.

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).

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
When the 0xe820 memory map method doesn't work for whatever reason (broken BIOS),
it currently just assumes to have 32 MB - it now also prints out a warning when
it does so.

the FS release/remove vnode calls. Extended comments.
Added "flags" parameter to unmount.

(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).

Ceccherini for the hint.
The first port ID is now 1 and not 0 anymore.

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.

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()

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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10203 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

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

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.

fill_thread_info() did not correctly set thread_info::stack_end.

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.

- 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

create_area() can now only create kernel areas.

for temporary memory anymore, it's the store's responsibility to do that
correctly now, and that functionality is reached via the vm_cache using
vm_cache_set_minimal_commitment().
Therefore, the vm_store commit() function now returns a status instead of
the size that could be commited.
Replaced the max_commit mechanism with one that cares about the available
memory, stores can reserve and unreserve such memory. The anonymous_commit()
will now fail in case it could not reserve the needed amount of memory.

me to improve the slider colors a bit.
Therefore, console_set_color() no longer clears bit 8 from the background color.
Now no longer tries to change the palette in non-8-bit modes; that fixes
the strange colors I got in high and true color modes (VESA palette changing

serial_init() is now called from start().
Changed the way the serial debug output is served: instead of having
the console node to dump everything to serial, too, only dprintf()
triggers serial output now.
dprintf() is now silent unless in debug mode; serial output could
be enabled separetely, though (currently only at build time).
There is no need to disable serial output while the menu is running.
Removed unnecessary grist from the Jamfile.

some stuff blinked and had wrong colors), we now have a new color scheme
in the boot loader. Not perfect, but looks okay and the same on Bochs and
real machines.
Made changing the colors again easier by moving most colors to constants.
We now have 3 lines for help texts.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9754 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now clears the screen and scrolls using the current colors (which allows
for other background colors than black).
console_set_color() no longer allows to set the 8 bit of the background
color which indicates blinking.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9753 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added comments about which colors can be used for what (unlike Bochs,
real systems support blinking modes, and therefore only 7 bits for
the background color).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9752 a95241bf-73f2-0310-859d-f6bbb57e9c96
or I am messing things up (it will now use good old VGA palette programming).
This fixes the strange colors on my system, should investigate on how to
properly use the VESA stuff here.
Debug output now goes through dprintf().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9751 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now correctly removes the partitioning system from a device when it is no longer
needed. Also resets the parent pointer of its children.
Debug output now goes through dprintf() rather than printf().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9748 a95241bf-73f2-0310-859d-f6bbb57e9c96
the partition was deleted, but never removed from the partition list.
No longer prints out the root directory contents of all file systems.
Debug output now uses dprintf() rather than printf().

in the wrong direction for some time now, corrupting the argument area (user
apps would crash).
B_SYSTEM_TEAM is now reserved, so that no team can be created there.
Fixed some warnings when debug output is enabled.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9719 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed console_reader() function to keyboard_reader().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9718 a95241bf-73f2-0310-859d-f6bbb57e9c96
The inode now keeps track of the number of readers/writers.
Inode::BytesInChain() is now only used protected by the request lock.
Implemented some missing POSIX demands:
- when the last writer is closed, all waiting read requests are aborted
- pipefs_write() now returns EPIPE and signals the current thread with
SIGPIPE in case there are no readers left
- pipefs_read() will now return 0 in case there are no writers and no
unread buffers left in the pipe.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9717 a95241bf-73f2-0310-859d-f6bbb57e9c96
Correctly implemented devfs_create() - it will now open the an already
existing file if O_EXCL is not set, and no longer fail with EROFS.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9716 a95241bf-73f2-0310-859d-f6bbb57e9c96
divided into several parts, it could happen that overwrite the whole data
portion with data beyond the part that should have been read.

was running. Thanks a lot to Jerome Duval who found this!
Since TTY ECHO mode doesn't look too well with the old shell, it will directly
start "sh" now, which should be the bash.
No longer prints out the TTY used when started, but now sets (as usually
done in BeOS) the TTY environment variable.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9697 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed the fs_initialize_volume() function, as it's probably not going
to be needed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9695 a95241bf-73f2-0310-859d-f6bbb57e9c96
absolutely no reason to move them to B_SYSTEM_TEAM (additionally, during
startup, set_sem_owner() may crash).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9693 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the last argument of _kern_mount() to be a string rather than a void pointer.
Greatly reduced the stack usage of _user_mount(); it now uses KPath instead
of on stack paths. It now also copies the parameter argument on the heap.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9692 a95241bf-73f2-0310-859d-f6bbb57e9c96
devfs_read_link() and rootfs_read_link() could write beyond the buffer
size passed in (off by one).
The comment for _kern_read_link() didn't fit to what the function really
did.
common_read_link() no longer null terminates the link - it's the file
system's responsibility to do that.
fs_read_link() is not supposed to return the length of the link anymore,
but only B_OK for success.
Note, we deviate slightly from POSIX here, where even a buffer too small
would be filled, and no terminating null byte has to be written at all.
We always return an error in case the buffer is too small, and the link
is not partially copied into the buffer.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9652 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made the FS internal API a bit more consistent.
Removed devfs_unlink(), and devfs_rename() (which was just returning EROFS
anyway) - the devfs now appears completely read-only to the user. All
changes are triggered by kernel internal APIs (most usually through either
the devfs itself (old style drivers), the disk_device_manager, or the
standard device_manager).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9645 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also implemented the now needed devfs_read_link() function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9644 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9639 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9530 a95241bf-73f2-0310-859d-f6bbb57e9c96
the "cursor".
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9527 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9510 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

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

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.
