Oliver Tappe 571d840abf * dropped svn:keywords property from all files that carried it
to avoid recurring problems during migration of subversion checkouts
  (restored binary files that were garbled by subversions during checkout)
* added appropriate svn:mime-type property for problematic (binary) files
* removed a single (mistyped) svn:mimetype property 
* dropped svn:eol-style property for cleanup (they all contained 'native')

Axel Dörfler 47000651b5 * Rewrote USB_rle.h, USB_spec.h, and midi_driver.h. I did not reproduce the
documentation found in those headers - this stuff should go into the Haiku
  Book instead (although I'm not even sure the USB_rle.h, and midi_driver.h
  are really needed any longer).

François Revol 7e26ad5af7 Add functions to the old-style PCI bus manager to reserve a device from an old-style driver for exclusive use. This should help making OSS and native audio drivers mutually exclusive. Used in es1370 and hda drivers as examples. OSS must still be fixed to use it too though.

Axel Dörfler 533cba7eff bonefish + axeld:
* Reverted r31809 as it introduced a race condition; if the I/O request had been
  notified, it could already been deleted at that point.
* Instead, we need to notify the request in each file system/driver that uses
  it. Added new notify_io_request() function that does that exactly.
* Added a TODO comment to the userlandfs where the request notification needs
  a bit more thought.

Michael Lotz 8e1857f795 * Completely rework the USB HID driver to make use of the HID framework
introduced earlier.
* Reworked the previous device classes to make them ProtocolHandlers handling
  their respective input_server <-> driver protocol.
* Implement setting report item data and building/sending reports based on that.
* Remove the old HID parsing code.

This enables us to use all HID devices as we now parse and use the HID
descriptors/reports. Non-boot-porotocol devices should therefore work.

The next step will be to implement a generic input/output framework in userland
that can communicate with a generic protocol handler in usb_hid. This will then
enable applications to make use of all the non-mapped HID stuff directly.

Ingo Weinhold 1cc5e46925 Added offset and size parameters to create_child_partition() and
KPartition::CreateChild(). CreateChild() calls AddChild(), which publishes
the new partition, though at that point offset and size were not set, so that
the published devices would not be usable.

Stephan Aßmus 7f33d2c159 I am trying to help a bit with the transition from IDE to ATA stack.
* Copied ide_adapter.h as ata_adapter.h in attempt to further
  separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
  specifically ata_types.h, ata_adapter.h and bus/ATA.h,
  they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
  image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
  removed the capability indication from the busses/ata drivers
  and ata_adapter.h.

The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.

* Cleaning up the old ATA bus_manager as well as some license headers missing.

Ingo Weinhold 3cf43c2651 Removed the fs_vnode_ops::create_dir() parameter for returning the ID of the
newly created dir. The VFS really doesn't need it and for some file systems
it might not be easy to get by. Several file systems (e.g. rootfs and fat)
were ignoring the parameter anyway.

Michael Lotz 49004dc730 Remove the additional fs_vnode_ops arugment from get_vnode() again as it's not

the changes to the other filesystems.

Michael Lotz 3684e40bb8 * Introduce a (private) flag B_NO_HANDLED_INFO for install_io_interrupt_handler.
It causes the interrupt handler to be inserted at the very end of the list
  instead of at the top. It is intended to be used as a workaround when a
  interrupt handler cannot know if it actually handled the interrupt. This
  should never be used by native drivers. Also if we know that the result is
  not valid because of this flag we won't disable the vector in case we count
  many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
  instead of the doubly linked one used with insque and remque as it greatly
  simplifies things for such an easy use case and is more compact.

Michael Lotz a26c243920 * Adding volume ops to the overlay filesystem.
* Remove the previous method of applying the overlay by flags. In the future the
  overlay can just be mounted as a filesystem layer. This is probably how layers
  were intended to work in the first place.
* Move the filesystem module info and filesystem name from the fs_mount to the
  fs_volume structure. Filesystem layering is done by having multiple layered
  volumes and we want to be able to have a different fs per layer.
* Adapt VFS code to this move.
* Implement mounting layered filesystems. Specifying multiple filesystems
  separated by a colon on mount will cause the layers to be set up and the
  corresponding filesystems to be mounted at that layer.

2009-02-14 20:30:49 +00:00
Michael Lotz 00405f2286 * Add an additional argument to get_vnode() that gets the fs_vnode_ops of the
node. That is needed for a layered filesystem to be able to construct a full
  fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
  use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
  flags field of a fs get_vnode call. A filesystem can use this flag to indicate
  that it doesn't support the full set of fs features (attributes, write support)
  and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
  on a filesystem where attributes aren't supported. It does currently only
  support reading attributes/attribute directories though. All other calls are
  just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
  is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
  so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
  later to only trigger where there are features on a CD that need emulation
  at all.

If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

Michael Lotz c33667d400 Fixing warnings under GCC4 in preparation to enable -Werror there as well:
* Replaced the use of offsetof() for structs that aren't PODs. Add a
  offset_of_member() macro to util/khash.h because that's what it's used for
  in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
  GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
  it pointed out at least one bug that is fixed here as well.

Ingo Weinhold 4612433715 * Added parameter "size_t align" to file_map_translate(). If > 1, the
vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
  underlying device or BFS block size, whatever is less), which should
  be fine, since file data are only stored in BFS blocks. This totally
  avoids any partial operations at the I/O scheduler level, thus saving
  disk operations. Not that I could measure any performance difference.
  Theoretically it should help a lot though, particularly when dealing
  with lots of small files, since we avoid using bounce buffers, which
  are (a) limited in number and (b) require copying of the data.

Axel Dörfler 06ba3f0acb * Added two new ways to retrieve an icon from a device:
- B_GET_ICON_NAME: returns the name of an icon. This will then be read from
    a predefined location on disk (not yet implemented). This would also allow
    to add specifiers like "-boot", or "-fat|bfs|ntfs|...", and have special
    icons for those.
  - B_GET_VECTOR_ICON: retrieves the vector icon of a device, if any.
* get_device_icon(BBitmap*, ...) now supports other color spaces than B_CMAP8.
* Added get_device_icon(), BPartition::GetIcon(), and BVolume::GetIcon()
  variants that can also retrieve the icon data directly (like
  BNodeInfo::GetIcon()).
* Reenabled the previous BPartition::GetIcon(), based on a patch by
  Justin O'Dell - this fixes #1391.
* Tracker's MountMenu class now uses B_RGBA32 icons, instead of B_CMAP8.
* Added vector icon to scsi_disk, and scsi_cd. The former doesn't have any
  special removable icon, though.
* Header cleanup, added/updated license, whitespace cleanup.
* Marked deprecated/obsolete driver ioctls in Drivers.h.
* Removed OpenBeOS namespace in the headers I touched that still had them.

Axel Dörfler 70e2d4ac43 * Replaced the B_BLOCK_DEVICE_* defines with B_DMA_* defines that better match
our dma_restrictions structure (but we're using blocks instead of bytes,
  since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
  the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
  segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

Axel Dörfler 24593e2c79 * First baby steps in letting our drivers use the new I/O request/scheduler
architecture: for now, we do this on the lowest layer only, therefore all
  requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
  exporting a device on their own, and use an I/O scheduler with an appropriate
  DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
  you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
  of the previous read/write functions, moved preferred CCB size from those
  functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
  it); it's sometimes triggered by the code now, and I haven't yet looked into
  the issue -- doesn't seem to harm, at least.

Axel Dörfler 3c1a3047a4 * Added file_cache_is_enabled() function.
* Added file_map_set_mode() function that you can use to keep a whole file
  cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
  not only precache all file_io_vecs when called, but it will also cause all
  file_map_translate() calls to fail that would require further caching (ie.
  if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).

Ingo Weinhold 7491000f20 Added functions file_cache_{disable,enable}(). They allow to disable
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

Axel Dörfler 9f6ae76f02 * Added acquire_vnode() call that you can use to get another reference to an
inode - unlike get_vnode() the busy flag won't prevent you from getting that
  reference.
* Changed put_vnode() to return an error in case the vnode couldn't be found.

Ingo Weinhold 7f12cc54a7 * It is now supported that I/O operations and requests are only handled
partially (e.g. due to hitting the end of file). The respective
  classes have grown new methods and attributes to deal with that. The
  "finished" callbacks have got additional parameters to indicate
  whether the transfer was only partial and how much has been
  transferred. Other callbacks and functions have a size_t* in/out
  parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
  of the underlying FS's {read,write}_pages() hooks (those should be
  unused now). Furthermore they've got an additional "flags" parameter,
  which is passed to IORequest::Init(), i.e. it allows to specify that
  the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
  pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
  pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
  do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
  driver I/O requests are passed all the way from the VFS/VM to the
  driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
  methods.
* Disabled some debug output by default. Added new optional debug
  output.

Ingo Weinhold 7df40c23f6 Added handy function volume_for_vnode() which returns the fs_volume for
a given given fs_vnode.

Ingo Weinhold ec598fe493 * Added FS interface hooks io() and cancel_io(). The former is supposed
to provide asynchrounous (or only synchronous, if asynchronous is not
  supported) I/O request support. It will eventually replace
  {read,write}_pages(). None of the FS implementations implement them
  yet.
* Implemented some support functions for request-based I/O. File system
  implementations can use do_fd_io() which passes an I/O request to the
  layer responsible for a given FD, and do_iterative_fd_io(), which
  translates a request for a file to subrequests for the underlying
  device and passes them on. Both fall back to synchrounous processing
  when the io() hook is not supported.
  Furthermore added vfs_synchronous_io() which should be handy for the
  devfs to perform io_requests synchronously for devices that don't
  support the io() hook.

Ingo Weinhold 6e60a6ac03 Added function get_memory_map_etc() which works similar to
get_memory_map(), but has a saner semantics and allows specifying a
team.

Ingo Weinhold 902559ce32 * Added a mutex to IORequest. It doesn't look like we can get around
using a lock and I'm not very much in favor of a global one.
* Added "finished" callback to IORequest.
* IOOperation::Finish() no longer invokes its parent request's
  ChunkFinished(). The finisher does this instead. ChunkFinished()
  can optionally remove the chunk from the parent.
* Added IORequest::Wait() which waits for the completion of the request.
* Introduced IORequestChunk::ResetStatus() to make setting the status to
  "pending" somewhat more explicit.
* Implemented the missing IOScheduler::SetCallback() methods.
* The NotifyAll() calls on the IOScheduler's condition variables were
  missing, so it just waited forever.
* Added some more debug output.
