a PCI memory mapped region, rman_get_bushandle() returns what happens
to be a kernel virtual address pointing to the base of the PCI shared
memory window. However this is not the behavior on all platforms:
the only thing you should do with the bushandle is pass it to the
bus_spare_read()/bus_space_write() routines. If you actually do want
the kernel virtual address of the base of the PCI memory window, you
need to use rman_get_virtual().
The problem is that at the moment, rman_get_virtual() returns a physical
address, which is bad. In order to get the kernel virtual address we
need, we have to play with it a little.
Presumeably this behavior will be changed, but in the meantime the
Tigon driver won't work. So for the moment, I'm adding a kludge to
make things happy on the alpha: the correct kernel virtual address
is calculated from the value returned by rman_get_virtual(). This
should be removed once rman_get_virtual() starts doing the right
thing.
This should make the Tigon actuall work on the alpha now.
ethernet controllers based on the AIC-6915 "Starfire" controller chip.
There are single port, dual port and quad port cards, plus one 100baseFX
card. All are 64-bit PCI devices, except one single port model.
The Starfire would be a very nice chip were it not for the fact that
receive buffers have to be longword aligned. This requires buffer
copying in order to achieve proper payload alignment on the alpha.
Payload alignment is enforced on both the alpha and x86 platforms.
The Starfire has several different DMA descriptor formats and transfer
mechanisms. This driver uses frame descriptors for transmission which
can address up to 14 packet fragments, and a single fragment descriptor
for receive. It also uses the producer/consumer model and completion
queues for both transmit and receive. The transmit ring has 128
descriptors and the receive ring has 256.
This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus
so that it can be compiled as a loadable kernel module. Support for BPF
and hardware multicast filtering is included.
critical mbuf fields to sane values. Simplify the use of ETHER_ALIGN to
enforce payload alignment, and turn it on on the x86 as well as alpha
since it helps with NFS which wants the payload to be longword aligned
even though the hardware doesn't require it.
This fixes a problem with the ti driver causing an unaligned access trap
on the Alpha due to m_adj() sometimes not setting the alignment correctly
because of incomplete mbuf initialization.

likely that fewer than 50 would do.
Hashing is done from udev_t to dev_t with a prime number
remainder hash, experiments show no better hash available
for decent cost (MD5 is only marginally better) The prime
number used should not be close to a power of two, we use
83 for now.
Add new checkalias2() to get around the loss of info from
dev2udev() in bdevvp();
The aliased vnodes are hung on a list straight of the dev_t,
and speclisth[SPECSZ] is unused. The sharing of struct
specinfo means that the v_specnext moves into the vnode
which grows by 4 bytes.
Don't use a VBLK dev_t which doesn't make sense in MFS, now
we hang a dummy cdevsw on B/Cmaj 253 so that things look sane.

gigabit ethernet adapters. This includes two single port cards
(single mode and multimode fiber) and two dual port cards (also single
mode and multimode fiber). SysKonnect is currently the only
vendor with a dual port gigabit ethernet NIC.
The ports on dual port adapters are treated as separate network
interfaces. Thus, if you have an SK-9844 dual port SX card, you
should have both sk0 and sk1 interfaces attached. Dual port cards
are implemented using two XMAC II chips connected to a single
SysKonnect GEnesis controller. Hence, dual port cards are really
one PCI device, as opposed to two separate PCI devices connected
through a PCI to PCI bridge. Note that SysKonnect's drivers use
the two ports for failover purposes rather that as two separate
interfaces, plus they don't support jumbo frames. This applies to
their Linux driver too. :)
Support is provided for hardware multicast filtering, BPF and
jumbo frames. The SysKonnect cards support TCP checksum offload
however this feature is not currently enabled (hopefully it will
be once we get checksum offload support).
There are still a few things that need to be implemeted, like
the ability to communicate with the on-board LM80 voltage/temperature
monitor, but I wanted to get the driver under CVS control and into
-current so people could bang on it.
A big thanks for SysKonnect for making all their programming info

Other minor cosmetic cleanup. Add in support for the Qlogic ISP

whether we were successful in mapping request and response queues
(and fibre channel scratch space).
not having SCSI_ISP_SCCLUN config defined if we don't have f/w for

define so that some attempt at a synthetic WWN can be made in case
NVRAM isn't readable).
Change initialization of options a bit- don't use ADISC. Set
FullDuplex mode if config options tells us to do so. Do not use
FULL_LOGIN after LIP- it's the right thing to do but it causes too
much loop disruption (Loop Resets). Sanity check some default
values. Redo construction of port and node WWNs based upon what we
have- if we have 2 in the top nibble, we can have distinct port
and node WWNs. Clean up some SCCLUN related code that we obviously
had never compiled (:-(). Audit commands coming int ispscsicmd and
don't throw commands at Fibre devices that do not have Class 3
service parameters TARGET ROLE defined.
Clean up f/w initialization a bit. Add Fabric support (or at least
the first blush of it). Whew - way too much to describe here.
Basically, after a LIP, hang out until we see a Loop Up or a Port
DataBase Change async event, then see if we're on a Fabric
(GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric
controller for fabric devices using the GetAllNext SNS subcommand.
As we find devices, announce them to the outer layer. Try and do
some guard code for broken (Brocade) SNS servers (that get stuck
in loops- gotta maybe do this a different way using the GP_ID3 cmd
instead). Then do a scan of the lower (local loop) ids using a
GET_PORT_NAME to see if the f/w has logged into anything at that
loop id. If so, then do a GET_PORT_DATABASE command. Do this scan
into a local database. At this point we can say the loop is 'Ready'.
After this, we merge our local loop port database with our stored
port database- in a as yet to be really fully exercised fashion we
try and follow the logic of something having moved around. The
first time we see something at a Loop ID, we fix it, for the purpose
of this system instance, at that Loop ID. If things shift around
so it ends up somewhere else, we still keep it at this Loop ID (our
'Target') but use the new (moved) Loop ID when we actually throw
commands at it. Check for insane cases of different Loop IDs both
claiming to have the same WWN- if that happens, invalidate both.
Notify the outer layer of devices that have arrived and devices
that have gone away. *Finally*, when this is done, search the
softc's database of Fabric devices and perform logout/login actions.
The Qlogic f/w maintains logout/login for all local loop devices.
We have to maintain logout/login for fabric devices- total PITA.
Expect to see this area undergo more change over time.
Change some fcp parameter structures such that we can get the portid
(24 bit value), get both node and port WWN, know whether we're on a fabric
or not, note whether we've ever seen the loop up, and note the current
state of the loop.
Replace the isp_pdb_t structure in fcparams with a reduced cost structure
that maintains a static relationship to 'Target', but can have the actual
loop ID used change (in case, post LIP, we discover things have moved
around). This also retains portid and node/port WWNs. This array gets
larger if we have fabric support compiled in.
Note special loop IDs that are invariate for this device- FL_PORT_ID
(0x7e) which tells us if there's a fabric controller present, FC_PORT_ID
and FC_SNS_ID (fabric controller port and fabric SNS server port). We don't
use the latter two for anything. IDs above FC_SNS_ID up through 255 are
available for mapping fabric devices to 'target' ids.
Add in a config define to set FC full duplex mode. Add in a define to
recognize the Qlogic 2200 boards. Add comments about ISPCTL commands.
Add and change some ISPASYNC enumes.

of the current interrupt trasaction.
- Do not schedule the next interrupt transaction if the pipe is being
aborted or the last round of the interrupt transaction ended with error.

- Call ums_disable() to abort the pipe.
- Do not wake up processes which has been waiting or polling for mouse
data. It won't be available anymore.

disable_intr() does non-recursive locking in the SMP case. This should
fix cy-driver-related panics when SMP is configured.

Allow chipset drivers to specify the direct-mapped DMA window's mask in
preparation for tsunami support. Previous chipsets' direct-mapped DMA
mask was always 1024*1024*1024. The Tsunami chipset needs it to be
2*1024*1024*1024

lose any information. Certain revisions of the aic7880 will not
perform the mirroring so to match all possiblities would double

in the transmit code: the TX descriptor ring, and a 'shadow' ring of mbuf
pointers, one for each TX descriptor. When transmitting a packet that
consists of several fragments in an mbuf chain, we link each fragment
to a descriptor in the TX ring, but we only save a pointer to the mbuf
chain. This pointer is saved in the shadow ring entry which corresponds
to the first fragment in the packet. Later, ti_txeof() can release the
whole chain with a single m_freem() call. (We need the second ring to
keep track of the virtual addresses of the mbuf chains.)
The problem with this is that the Tigon isn't actually through with the
mbuf chain until it reaches the last fragment (which has the TI_BDFLAG_END
bit set), however the current scheme releases the mbuf chain as soon as
the first fragment is consumed. This is wrong, since the mbufs can then
be yanked out from under the Tigon and modified before the other fragments
can be transmitted.
The fix is to make a one line change to ti_encap() so that it saves the
mbuf chain pointer in the shadow ring entry that corresponds to the last
fragment in TX ring instead of the first. This prevents the mbufs from
being released until the last fragment is transmitted.
