status stays on until the port is reset, this causes the interrupt to be
constantly retriggered on some controllers.

GetNthPciInfo().

all tests finally go through.

always set as the endpoint had an error) the address comparison failed and
the head was dead in the water with all further transfers timing out until
a subsequet cancel cleaned the mess up again.

functional except for isochronous transfers.

* This fixes several race conditions with the neon test suite that relied
on TCP sockets being gone after close, and their port being available again
(note, that is not what the TCP spec says, anyway, but it makes sense to
do so, since we already removed the time wait state for local connections).
* The endpoint manager is now using a mutex instead of a semaphore.
* TCPEndpoint::_Close() now notifies the senders/receivers instead of
_HandleReset().
* Besides ssl_closure(), all tests of the neon test suite seem to pass now.

on resources but still satisfy the scheduling policy. This works well, but
effectifly limits the bandwidth available as the interrupts aren't spread
across different frames.
* Implement finding the interrupt endpoint head for a certain interval.
* Deactivate endpoints that are going away until removing them is implemented.
* Allow short packets for all data phases.
* Disable tracing by default.
There you go, interrupt transfers should work as well. Should enable mice,
keyboards, hubs and other devices that use interrupt pipes. Note that it's
still easily possible that a single failed request will hang an endpoint and
prevent a device from working.

single td bulk transfers.
* Implement SubmitTransfer() for bulk transfers (interrupts will use the exact
same code path, but as their endpoints aren't yet setup, interrupt transfers
won't work).
* Handle the cancel case when finishing transfers. The descriptors of the
canceled transfers cannot be accessed by the controller so they can be freed.
Bulk transfers should work now, so devices only using control and bulk transfers
should too (anything using usb_disk for example). Note though that a transfer
error will cause the whole thing to fail miserably as the error case is not
yet handled correctly (failed descriptors aren't removed from the endpoint).
Therefore I suggest not testing with the memory stick with that important
presentation you haven't stored anywhere else...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25549 a95241bf-73f2-0310-859d-f6bbb57e9c96
pretty much the same strategy as UHCI. This does not leverage the done queue
the hardware provides us, but as it saves a lot of other overhead and allows
the structures to be smaller I think it is overall worth it.
* Removed now unnecessary stuff from the transfer descriptor struct.
* Directly acknowledge the done head interrupt as we do not use it either.
* Activate control endpoints by removing the skip bit when a transfer is scheduled.
* Correct the way the first descriptor is determined (the current tail becomes
the first descriptor while the current first descriptor becomes the tail).
* Remove the head_logical_descriptor field from the endpoint structure, as this
would simply get out of sync with the first td with no real way of updating.
* Stub out RemoveTransferFromEndpoint() as this needs reworking.
* Correct CreateDescriptorChain() signature and implement the method.
* Add ReadDescriptorChain() and ReadActualLength() to process finished transfers.
* Prepare for actual data transfers by renaming/regrouping transfer types.
* Fully clear out the new tail when switching (for the sake of it)
* Add some helpers and definitions to the hardware header.
* Add debugging facilities.
With all this transfers can now actually be scheduled and they are processed
when done. This brings control transfers to a usable state so setting the
device address and reading out/setting the configuration works. That means you
can now view your device using usb_dev_info, but since any other transfer type
besides control transfers isn't implemented yet the device will most probably
not yet do anything useful.

into the kernel:
* Added device_removed() function to the device level as well.
* A device_node now also tracks its published devices.
* Made the driver API more consistent with the device API; instead of the node,
they now get the driverCookie (so they now need to store the node themselves,
the driver cookie could be retrieved via the node).
Alternatively, one could either pass both, or have something similar to what
Ingo did for the file systems, ie. pass a structure that contains both
elements. Suggestions welcome.
* Implemented device node replacement when a better driver becomes available:
the new node (and its devices) is already published even though the old device
is still in use. The new device is B_BUSY until the old one is closed.
* Implemented an update cycle counter: this will prevent a device node from
being probed again, if there is no new driver since the last time; eventually
this will be moved into devfs, though.
* Driver removal and replacement now works as expected in all tested scenarios
(device removed, better driver installed, both with and without open device).

the manager reacts to opened devices.
* renamed *_device() functions to *_node() in the device manager API.
* made B_DEVICE_FIND_CHILD_FLAGS a generic flags field, and renamed it to

* added support for keeping a driver loaded as long as its device is available.
* implemented get_next_child_node().

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
still broken, since it doesn't work in C code.

stupid, I know it did check double buffering at one point, but I must have
removed that when messing with it. But copying anything from back to front
buffer is now not overwriting the cursor area anymore, which is painted
immediatly afterwards. Also moving the cursor invalidates only one rect

existing ECMDevice object. This allows for the link simply going down when a
device is unplugged and going up again when the device is replugged. The
nice thing is that due to the way our usb drivers work it doesn't matter
where you replug the device, so you can switch it from one port to another

updating the active pointer as otherwise the endpoints of the new alternate
would have been cleared instead of the old one (leaking endpoints).
* Only clear and re-initialize the endpoints of the interface we are setting
an alterntate. Otherwise we tear down all the device endpoints which would

* Extended the scope of the Revert feature to include changes to the time zone.
* Moved the Revert button out of the tab view, so that it indicates the above
visually. The window now handles the Revert feature.
* Added Others/Greenwhich time zone which is equivalent to an "unset" time zone.
