for now. This is a workaround and should be removed once we have proper
interrupt return values from FreeBSD drivers. Should work around interrupt
storms for shared interrupts with some network cards that use a FreeBSD driver.

first chunk of a possibly multi-buffer mbuf. This fixes#2840, thanks a lot!
* Fixed warning in _bus_dmamap_load_buffer().

caused lots of bugs (like #2758, and obviously also #1641). Thanks a lot!!

that makes drivers using it more independent from internal net_timer changes.
* Correctly implemented callout_active() using the new is_timer_running()
stack function.

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
structure (thus breaking BeOS binary compatibility), containing a
counter which is incremented whenever a thread has to wait for the
spinlock.
* Added macros for spinlock initialization and access and changed
code using spinlocks accordingly. This breaks compilation for BeOS --
the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
the team spinlocks.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25752 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Adjusted code using recursive locks respectively. The initialization
cannot fail anymore, and it is possible to use recursive locks in the
early boot process (even uninitialized, if in BSS), which simplifies
things a little.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

worked flawlessly this one time... (I got almost 10 MB/s with that one, now 7.5 MB/s with
the 3com driver)
* We need to acknowledge the interrupt in the handler, because else, the interrupt continues
to fire after the PIC interrupt is acknowledged by the kernel.
* It also helps a lot to turn off the interrupts on the device while xl_intr() is handling
the interrupt.
* When the slow handler is running, we now set the new "handling" field in the internal
interrupt handler which will not invoke the scheduler then (but only signals a handled
interrupt).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23085 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Accidently excluded the MII bus from being probed in r23019 - in fact, now all
devices have to be probed.

call this function if you don't know if a device has a direct reference to one of
its children. Since we want to be able to delete the root without having any knowledge
about its children, we now detach everything first, and then delete the entries.
This fixes a possible crashing bug when a preloaded driver (used for network boot)
tried to acquire its resources again at a later point.
* device_detach() and device_attach() now check if the device has an attach or detach
method at all.

functionality needs it.
* callout_init_mtx() now initializes the timer manually, since the stack
might not have been loaded yet (since a device is now attached in
init_driver()).
* Minor other fixes; the FreeBSD compatibility layer should now be functional
again.
* Accidently put pci.c into the repository, but that was never meant to happen.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23026 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed NETDEV() and DEVNET() macros and functionality.
* The exported devices are now attached to ifnet objects only, therefore, the
ifnet object now has the receive queue, and everything else a device could
need.
* There is now a root device where everything else is attached, it currently
only holds the pci_info structure, so it's more or less a PCI child.
* This simplified the device handling a bit everywhere.
* We now attach drivers already in init_driver() - this is needed as drivers
may publish more than one interface when being attached.
* Implemented device_delete_child(), device_attach() (which bus_generic_attach()
now uses), device_is_attached(), and device_is_alive().
* Therefore, if_initname() does now the actual job of registering the devices.
* On open, if_init() is called which comes pretty close to what our open()
is supposed to do.
* Updated ukphy.c to the one from FreeBSD 7 where used (we should probably
move that into the compat layer, anyway).
* The MII driver array must now be NULL terminated; therefore you don't need
to specify the count anymore.
* Moved PCI code from compat.c to bus.c.
* Moved the driver code from device.c to driver.c.
* Removed superfluous init_compat_layer() function.
* Fixed a few bugs, a few things weren't brought down correctly.
* The rtl8139 interrupt routine now checks if it really was the cause of the
interrupt - this code is not tested, either, it may not work (which would
then require a work-around like I did for the 3com driver).
* The HAIKU_PROTECT_INTR_REGISTER in the rtl8139 driver was pretty much useless
which is why I removed it.
* Probably introduced a lot of new bugs, though - I haven't tested this code
at all yet. It will probably just crash :-)

* The device path is currently inherited from its parent which might be revised later on (nameunit
is not y

(RELENG_7_BP).
* There are many white spots, though, most notable PCI MSI(-X) support, and
jumbo frames.
* Fixed removing interrupts for the INTR_FAST case. Since FreeBSD 7 added
a new interrupt "filter" mechanism, we can finally report if the interface
was handled by a device or not (though only very few devices support this
yet).
* Updated the 3com, rtl8139, e1000, and via_rhine drivers to the latest code
base. They all compile, but I haven't tested them after the changes yet!

be initialized when probe(0 is called. The driver now loads and works for a
while until it hangs. Looking into it.

device's attach() method twice - this would let every network device that found a MII PHY fall into
an endless loop on start. In other words 3com and VIA Rhine should now work fine.

reason the MII bus did not work as mediainit was never called.
* Got rid of the delayed MII bus scanning again; not only did it not solve the problem, it was
also completely unnecessary.
* Minor cleanup.

probing/attaching the MII bus should come later, though.

pmap_kextract() not vice versa, just like it is done in FreeBSD itself.
* Added missing contigmalloc() definition for kernel drivers.
* Fixed the "*_devclass defined but not used" warning.
* Fixed warnings.
* Added/adjusted (to our style guide) the license headers for the files I
touched.
* Minor cleanup.
