When specified it desigantes that the interrupt handler should not lock the
vector with a spinlock when executing the installed interrupt handlers. This
is necessary to allow the same interrupt vector to be handled in parallel on
different CPUs. And it is required for the CPU halt to work synchronously when
there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs
to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me.
Not locking is safe as long as it is guaranteed that no interrupt handler is
registered or removed while the interrupt handler is running. We can guarantee
this for the SMP interrupt handlers we install in arch_smp_init() as they are
never uninstalled. Probably this flag should be made private though.
Restored the SMP_MSG_FLAG_SYNC when entering the kernel debugger.

blocks into the new transaction, but it would set that transaction on all
blocks of the old transaction, too. Also, it did not correctly update the
num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did
return B_OK instead of the ID of the new transaction...
* get_writable_cached_block() did not correctly maintain the number of blocks
in the sub transaction.
* write_cached_block() did not free the original_data of a block when it wrote
it back as part of a previous transaction.
* Changed "cookie" for cache_next_block_in_transaction() to "long", so it will
be 64 bits when needed.
* Improved the API for detaching sub transactions: you can now get the blocks
of only the main (parent) transaction as well, added new
cache_block_in_main_transaction() function.
* BFS now flushes the log when there is no space left for the current
transaction.
* _WriteTransactionToLog() allocated a "vecs" array, but never freed it.
* _WriteTransactionToLog() now also supports detaching the current sub
transaction if the whole thing is getting too large (it will now also panic
if that doesn't work out).
* Removed a useless optimization: making the blocks available in the cache
isn't really needed, as all blocks in a transaction are locked into the
cache, anyway.
* Implemented Transaction::WriteBlocks().
* Minor cleanup, removed some dead code, fixed warnings in the fs_shell's
block_cache when compiled with debug output on.

transaction ends or has been aborted.
* BFS now listens for transactions when it created an inode to see if
the transaction will be aborted without freeing the inode (in which
case it will panic for now).
* Started implementing tracing support, but it's not working yet.
* Minor cleanup.

the complete extent info or not.
* file_map_translate() now cuts down the request to the file bounds.
* Adjusted BFS and FAT to the API changes.

that can be used by file systems.
* Changed the way the file cache works: instead of reading/writing to the
underlying device directly, it can now be used for any data source, ie.
also network file systems.
* As a result, the former pages_io() moved to the VFS layer, and can now be
called by a file system via {read|write}_file_io_vec_pages() (naming
suggestions are always welcomed :-)). It now gets an FD, and uses that to
communicate with the device (via its fs_{read|write}_pages() hooks).
* The file_cache_{read|write}() functions must now be called without holding
an I/O relevant file system lock. That allows the file cache to prepare the
pages without colliding with the page writer, IOW the "mayBlock" flag can
go into the attic again (yay!).
* This also results in a much better performance when the system does I/O and
is low on memory, as the page writer can now finally write back some pages,
and that even without maxing out the CPU :)
* The API changes put slightly more burden on the fs_{read|write}_pages()
hooks, but in combination with the file_map it's still pretty straight
forward. It just will have to dispatch the call to the underlying device
directly, usually it will just call its fs_{read|write}_pages() hooks
via the above mentioned calls.
* Ported BFS and FAT to the new API, the latter has not been tested, though.
* Also ported the API changes to the fs_shell. I also completely removed its
file cache level page handling - the downside is that device access is no
longer cached (ie. depends on the host OS now), the upside is that the code
is greatly simplified.

This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22643 a95241bf-73f2-0310-859d-f6bbb57e9c96
additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

physical partition, unlike get_partition() which returns the shadow
partition, if it exists.
* Added B_PARTITION_SHADOW[_CHILD] partition pseudo operation values for
the shadow_changed() hook, notifying a disk system, that a shadow
partition has been created.

system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

* the page writer don't allow to block, while all other writers do. This fixes
bug #1509. The reason the page writer needs this is because it marks several
pages from different caches as busy.
* Fixed a warning about ASSERT being defined already in BFS, since
util/DoublyLinkedList.h now includes debug.h.

vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.

content name are supported.
* Added file_system_module_info::flags (analogously to
partition_module_info::flags) which indicate which disk device
features the FS supports.
* Replaced the
file_system_module_info/partition_module_info::supports_*()
hooks by a get_supported_operations() hook and for partitioning
systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
though.
* _user_supports_initializing_partition() also checks whether the parent
partitioning system is content now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22043 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Adjusted the FS initialize() hook to have FD and partition_id
parameters like the other hooks instead of the partition path.
* Adjusted initialization in BFS accordingly.
* Implemented the FS initialization method in KFileSystem.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21788 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Simplified the notification framework: removed the updater stuff completely;
it was only there to account for some peculiarities of the node monitor which
we now solved differently.
* NotificationListener no longer includes a doubly linked list link for convenience;
it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
longer possible to just remove some flags separately, just to stop listening
completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
couldn't do a lot with the KMessage in the kernel without using a private API.
Now you will have to use the (private) notification manager to use the node monitor
from inside the kernel. At a later point, we might introduce a public API for that,
too.

add-ons accordingly and removed the syscall.
* Removed send_notification().
* Reimplemented notify_listener(). It used the unimplemented
send_notification(). Now it has a chance to work. Note that
notify_listener() is obsolete. I would already have removed it, if
there weren't lots of FS implementations still using it (Hint!).

* Renamed a few parameters of the FS module hooks:
- *file in the attribute functions to *vnode
- v to vnode
- I could barely restrain myself from renaming the "_*" parameters. I
understand this marks return parameters, but I'd prefer a nicer prefix
or suffix (that doesn't makes you think this is a private/internal
identifier) like "out", "ret", "return", "result", or something similar.
I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

This means that the usb_callback_func now takes a status_t instead of a uint32 status.
Also the error codes are now different. I don't see this as a real problem in binary compatibility, as the status codes were never really documented and most drivers just assumed that a nonzero status meant an error.
Source compatibility breaks for callback functions and error defines. I fixed (hopefully) all places in the tree that are currenty included in the image and affected by the change.
* Corrected error reporting in UHCI and EHCI using the new status codes.
* Fixed a memory leak in EHCI where the async advance interrupt was not triggered in time.
* Fixed another race condition in usb_raw that could cause a crash when a device is removed while a transfer is pending.

* Rewrote both headers on the way.
* The usb module now exports both, the v2 and v3 module_info.
* Changed the internals of the USB Stack to give out usb_ids instead of opaque handles to internal classes.
* Cleaned up some more of the Stack by moving members into other classes and removing unused stuff.
* Updated the usb_raw driver from v2 to v3 API.
Since both usb_hid (which still uses the v2 API) and usb_raw (which now uses the v3 API) work, I'd call it a success ;-)

- has_signals_pending() is not declared in Be headers, and it isn't declared in
our KernelExport.h anymore, too
- removed snooze_etc() from KernelExport.h, as it's already defined in OS.h
(and really exported by libroot.so).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12506 a95241bf-73f2-0310-859d-f6bbb57e9c96
Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
(though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
"status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
equivalent (and private) are_interrupts_enabled()
