The ICH on-board Ethernet and some i82559 chips have a bug which
will cause a PCI protocol violation if the chip receives a CU_RESUME
command as it is entering the IDLE state by deasserting #CLKRUN.
(This is the so-called "resume bug" that we previously had an incomplete
work-around for on ICH chipsets.)
The work-around is to disable Dynamic Standby Mode, such that the
chip will never deasert #CLKRUN. Dynamic Standby Mode is disabled
by clearing a bit in the EEPROM and updating the EEPROM (and EEPROM
checksum).
Unfortunately, the chip will only consult the EEPROM setting after
a PCI bus reset, so a system reboot is required once the EEPROM
has been updated (the EEPROM update only needs to happen once,
and the driver usses a warning instructing the user to reboot the
system once the work-around has been applied).
Issue pointed out by David Brownlee, and code more-or-less lifted
from FreeBSD.
(de)activate for pcmcia cards.
Implement detach/(de)activate for PCI cards.
Clean up internal state (free call-descriptors) if a controller is
detached while it has open connections.
B-channel and D-channel drivers separately) split the Fritz!PCI card
driver out of the isic driver.
The new device is called "ifpci" and uses the same D-channel driver as the
isic devices, but has it's own B-channel driver.
and move them in their proper places.
Move the BRI registry from layer 2 (duh!) to layer 4, so active cards
(which don't have layer 3 or layer 2 in their driver). Remove all remaining
hard coded controller and driver types. Remove any arbitrary hard coded
limits, at least those that show up in the internal API.
This fixes PR 15950.
would either:
1. Cause the machine to stop responding, or
2. Cause the currently playing voices to stop output.
With this change, voices are stopped on suspend, and continue from where they
left off on resume.
Unconst pointer to f/w in the ispdv structure. Too many compilers get
unhappy over our walking the array. Make casts as appropriate so that
initialization in structure is still happy.
Limit length of fabric to 256. This will all go away soon.
Do a cleaner case of keeping multiple CPUs/threads from reading the
same response queue entries.
the generic layer 4 and layer 3 management system.
This should make the layer 4 driver API LKM clean - finaly.
Make the Fritz!PCI driver work again after resent changes (oops!),

indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
multi-port cards (which need the shared-rom/intr stuff) and single-port cards
(which must not have it). previously we enabled sharing for all adaptec cards,
which caused problems if you had multiple single-port cards on the same PCI bus.
audio accelerators.
Mixing is done in hardware by the ASSP, but is limited to 4 simultaneous
channels due to the restricted "minisrc" image that we are currently
working with.
Due to limitations in the audio subsystem, I'm currently attaching multiple
'audio' devices to 'esa', one for each voice. Because of this hack, the
default ESA_NUM_VOICES is 1.
