Because of using more clear and same time more functional codec parser
new driver is able to handle more codecs, use them better then before and
without most of previous quirks. All of tested codecs itself manage playback,
record, input mixing and monitoring quite fine. In all of investigated
trouble cases problem was found or in nonstandard codec usage or incorrect
codec configuration made by BIOS. Most of that cases could be fixed using
device hints, some of which are already included to the driver.
New driver supports multiple codecs per HDA bus, multiple audio function
groups per codec and multiple logical sound devices per audio function group.
So don't worry when you get several PCM devices instead of one, it is normal.
It is usual situation with powerful codecs to provide, for example, 3 PCM
devices: one for 7.1 playback and main recording, one for headset and one
for digital SPDIF I/O.
New driver implements Universal Audio Architecture (UAA) much better then
previous one. Most information about recommended codec usage now taken from
the codec configuration registers initialized by BIOS. User may alter that
configuration using device hints to reconfigure logical audio devices to
his needs in a very broad range up to the limits of the codec functionality.
New driver supports digital PCM playback and AC3 pass-through. I am not sure
about completeness of this implementation, but I have several success stories
including my own. Vchans subsystem does not support AC3 pass-through so it
had to be disabled for that devices at this moment.
New driver is ready for multichannel playback, but until our OSS is unable
to use this it will just duplicate same stereo stream into all channel
pairs.
New driver supports suspend/resume. I am unable to really test this part
myself, but I have got several success stories.
Driver has very informative verbose boot messages. So if you have any
questions or problems - enable and read them first.

the free list and in this way avoid contention on the w_mtx.
In order to make the code simple, we rely on the rule that when the head
has not a child it also doesn't have other subsequent entries.
Actually this assertion is broken because we can free all the head
children and quit witness_unlock() with the head still allocated, with no
children and subsequent entries present.
Fix this by shifting the head if other entries are present and still
freeing the object, but leaving always an head.
- Fix witness_thread_has_locks() in order to report, correctly, if the

- Fix nexus_setup_intr() abuse of setting up multiple IRQs in one go. Calling
arm_setup_irqhandler() in loop is bogus, as there's just one cookie given
from the caller and it is overwritten in each iteration so that only the
last handler's cookie value prevails.
- Proper intr masking/unmasking handling: the IRQ source is masked at PIC level
only after the last handler has been removed from the list.

isn't fixed to only open the network device once and not do a open

machines perform an auto-negotiation with every open which in turn
causes netbooting to take horribly long if we open and close the

checking the first function of each slot on bus 0 using both the
memory-mapped config access and the older type 1 I/O port config access.
If we find a slot that is only visible via the type 1 I/O port config
access, we flag that slot. Future PCI config transactions to flagged
slots on bus 0 use type 1 I/O port config access rather than memory mapped
config access.
