This defines a new bhnd_erom_if API, providing a common interface to device
enumeration on siba(4) and bcma(4) devices, for use both in the bhndb bridge
and SoC early boot contexts, and migrates mips/broadcom over to the new API.
This also replaces the previous adhoc device enumeration support implemented
for mips/broadcom.
Migration of bhndb to the new API will be implemented in a follow-up commit.
- Defined new bhnd_erom_if interface for bhnd(4) device enumeration, along
with bcma(4) and siba(4)-specific implementations.
- Fixed a minor bug in bhndb that logged an error when we attempted to map the
full siba(4) bus space (18000000-17FFFFFF) in the siba EROM parser.
- Reverted use of the resource's start address as the ChipCommon enum_addr in
bhnd_read_chipid(). When called from bhndb, this address is found within the
host address space, resulting in an invalid bridged enum_addr.
- Added support for falling back on standard bus_activate_resource() in
bhnd_bus_generic_activate_resource(), enabling allocation of the bhnd_erom's
bhnd_resource directly from a nexus-attached bhnd(4) device.
- Removed BHND_BUS_GET_CORE_TABLE(); it has been replaced by the erom API.
- Added support for statically initializing bhnd_erom instances, for use prior
to malloc availability. The statically allocated buffer size is verified both
at runtime, and via a compile-time assertion (see BHND_EROM_STATIC_BYTES).
- bhnd_erom classes are registered within a module via a linker set, allowing
mips/broadcom to probe available EROM parser instances without creating a
strong reference to bcma/siba-specific symbols.
- Migrated mips/broadcom to bhnd_erom_if, replacing the previous MIPS-specific
device enumeration implementation.

Idle page zeroing has been disabled by default on all architectures since
r170816 and has some bugs that make it seemingly unusable. Specifically,
the idle-priority pagezero thread exacerbates contention for the free page
lock, and yields the CPU without releasing it in non-preemptive kernels. The
pagezero thread also does not behave correctly when superpage reservations
are enabled: its target is a function of v_free_count, which includes
reserved-but-free pages, but it is only able to zero pages belonging to the
physical memory allocator.

Essentially, this is a literal copy of the code in sys/compat/cloudabi64,
except that it now makes use of 32-bits datatypes and limits. In
sys/conf/files, we now need to take care to build the code in
sys/compat/cloudabi if either COMPAT_CLOUDABI32 or COMPAT_CLOUDABI64 is
turned on.
This change does not yet include any of the CPU dependent bits. Right
now I have implementations for running i386 binaries both on i386 and
x86-64, which I will send out for review separately.
This driver only supports 10Mb Ethernet using PIO (the hardware supports

This is a driver for a pre-ATAPI ISA CD-ROM adapter. As noted in
the manpage, this driver is only useful as a backend to cdcontrol to
play audio CDs since it doesn't use DMA, so its data performance is
"abysmal" (and that was true in the mid 90's).
The module works together with ipfw(4) and implemented as its external
action module.
Stateless NAT64 registers external action with name nat64stl. This
keyword should be used to create NAT64 instance and to address this
instance in rules. Stateless NAT64 uses two lookup tables with mapped
IPv4->IPv6 and IPv6->IPv4 addresses to perform translation.
A configuration of instance should looks like this:
1. Create lookup tables:
# ipfw table T46 create type addr valtype ipv6
# ipfw table T64 create type addr valtype ipv4
2. Fill T46 and T64 tables.
3. Add rule to allow neighbor solicitation and advertisement:
# ipfw add allow icmp6 from any to any icmp6types 135,136
4. Create NAT64 instance:
# ipfw nat64stl NAT create table4 T46 table6 T64
5. Add rules that matches the traffic:
# ipfw add nat64stl NAT ip from any to table(T46)
# ipfw add nat64stl NAT ip from table(T64) to 64:ff9b::/96
6. Configure DNS64 for IPv6 clients and add route to 64:ff9b::/96
via NAT64 host.
Stateful NAT64 registers external action with name nat64lsn. The only
one option required to create nat64lsn instance - prefix4. It defines
the pool of IPv4 addresses used for translation.
A configuration of instance should looks like this:
1. Add rule to allow neighbor solicitation and advertisement:
# ipfw add allow icmp6 from any to any icmp6types 135,136
2. Create NAT64 instance:

CloudABI executables already provide support for passing in vDSOs. This

Though I don't have any plans to optimize any system calls right now,
let's go ahead and already pass in a vDSO. This will allow us to
simplify the executables, as the traditional "syscall" shims can be

Chelsio NICs are a bit unique compared to some other NICs in that they
expose different functionality on different physical functions. In
particular, PF4 is used to manage the NIC interfaces ('t4nex' and 't5nex').
However, PF4 is not able to create VF devices. Instead, VFs are only
supported by physical functions 0 through 3. This commit adds 't4iov'
and 't5iov' drivers that attach to PF0-3.
One extra wrinkle is that the iov devices cannot enable SR-IOV until the
firwmare has been initialized by the main PF4 driver. To handle this
case, a new t4_if kobj interface has been added to permit cross-calls
between the PF drivers. The PF4 driver notifies sibling drivers when it
is fully attached. It also requests sibling drivers to detach before it
detaches. Sibling drivers query the PF4 driver during their attach
routine to see if it is attached. If not, the sibling drivers defer
their attach actions until the PF4 driver informs them it is attached.
VF devices are associated with a single port on the NIC. VF devices
created from PF0 are associated with the first port on the NIC, VFs
from PF1 are associated with the second port, etc. VF devices can
only be created from a PF device that has an associated port. Thus,
on a 2-port card, VFs are only supported on PF0 and PF1.

This is the initial framework to call into the MCI HAL routines and drive
the basic state engine.
The MCI bluetooth coex model uses a command channel between wlan and
bluetooth, rather than a 2-wire or 3-wire signaling protocol to control things.
This means the wlan and bluetooth chip exchange a lot more information and
signaling, even at the per-packet level. The NICs in question can share
the input LNA and output PA on the die, so they absolutely can't stomp
on each other in a silly fashion. It also allows for the bluetooth side
to signal when profiles come and go, so the driver can take appropriate
control. There's also the possibility of dynamic bluetooth/wlan duty cycle
control which I haven't yet really played with.
It configures things up with a static "wlan wins everything" coexistence,
configures up the available 2GHz channel map for bluetooth, sets a static
duty cycle for bluetooth/wifi traffic priority and drives the basics needed to
keep the MCI HAL code happy.
It doesn't do any actual coexistence except to default to "wlan wins everything",
which at least demonstrates that things do indeed work. Bluetooth inquiry frames
still trump wifi (including beacons), so that demonstrates things really do
indeed seem to work.
Tested:
* AR9462 (WB222), STA mode + bt
* QCA9565 (WB335), STA mode + bt
TODO:
* .. the rest of coexistence. yes, bluetooth, not people. That stuff's hard.
* It doesn't do the initial BT side calibration, which requires a WLAN chip

* The 1-ant and 2-ant configuration bits aren't being set correctly in
if_ath_btcoex.c - I'll dig into that and fix it in a subsequent commit.
* It's not enabled by default for WB222/WB225 even though I believe it now

This patchset adds support to bhnd_chipc for sharing SYS_RES_MEMORY
resources with its children, allowing us to hang devices off of
bhnd_chipc that rely on access to a subset of the device register space
that bhnd_chipc itself must also allocate.
We could avoid most of this heavy lifting if RF_SHAREABLE+SYS_RES_MEMORY
wasn't limited to use with allocations at the same size/offset.
As a work-around, I implemented something similar to vga_pci.c, which
implements similar reference counting of of PCI BAR resources for its
children.
With these changes, chipc will use reference counting of SYS_RES_MEMORY
allocation/activation requests, to decide when to allocate/activate/
deactivate/release resources from the parent bhnd(4) bus.
The requesting child device is allocated a new resource from chipc's
rman, pointing to (possibly a subregion of) the refcounted bhnd resources
allocated by chipc.
Other resource types are just passed directly to the parent bhnd bus;
RF_SHAREABLE works just fine with IRQs.
I also lifted the SPROM device code out into a common driver, since this
now allows me to hang simple subclasses off of a common driver off of both
bhndb_pci and bhnd_chipc.
