o Grab the MAC address out of the CIS if the card has the special
3Com 0x88 tuple. Most 3Com cards don't have this tuple, but we
prefer it to the eeprom since it only appears to be present when
the eeprom doesn't have the info. So far, I've only observed this
on my 3C362 and 3C362B cards, but the NetBSD driver implies that
the 3C362C also has this tuple, and that some 3C574 cards do too (none
of mine do). ep_pccard_mac was written after looking at the NetBSD
code.
o Store the enet addr in the softc for this device, so we can use the
overridden MAC to set the station address.
o Create a routine to set the station address and use it where we need it.
o setup the cmd shitfs and such before we call ep_alloc(), and remove
setting up the cmd shift value there. It initializes to 0, and those
attachments that need to frob it do so before calling ep_alloc.
o Remove some obsolete comments
o No longer a need to export ep_get_macaddr, so make it static
o ep_alloc already grabs the EEPROM id, so we don't need to grab it again
in ep_pccard_attach.
o eliminate unit, it isn't needed, fix some printfs to be device_printf
instead.

scan the CIS for interesting tuples. 95% of what can be obtained from
the CIS is harvested by the pccard layer and presented to the user in
standard function calls. However, there are special needs at times
where the standard stuff doesn't suffice. This is for those special
cases.
CARD_SCAN_CIS(device_get_parent(dev), function, argp)
scans the CIS of the card, passing each tuple to function with
the tuple and argp as its arguments. Returning 0 continues the scan,
while returning 1 terminates the scan. The value of the last
invocation of function is returned from this function.

read with pccard_tuple_read_{1,2,3,4,n}(). You are reading

not only means that it's possible (though unlikely) that we hand out
differing tags for the same bus space, it also means that the tags
we handed out are not used during bus enumeration. Both affect our
ability to compare tags. Fix the first by initializing our tags only
once. Fix the second by testing if one of the tags to compare is our
tag and the other is a busspace_isa_{io|mem} tag and declare them
equal if so.
This fixes using uart(4) as the serial console on a ds10. That is,
the low-level console worked, but we could not match the resources
to one of the UARTs found during bus enumeration, which prevented

files after they were repo-copied to sys/dev/atkbdc. The sources of
atkbdc(4) and its children were moved to the new location in preparation
for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
order to not further scatter them over the whole tree which would have
been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
reason for the repo-copies was that some of the sources were misfiled,
e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
but are shareable between different atkbdc(4) bus front-ends into
atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
atkbdc(4). PS/2 controllers and input devices are used on a couple of
Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
the board it's either the only on-board mean to connect a keyboard and
mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
without isa(4) (e.g. for EBus-only machines). This ISA-specific part
isn't separated into its own source file, yet, as it requires more work
than was feasible for 6.0 in order to do it in a clean way. Actually
philip@ is working on a rewrite of psm(4) so a more comprehensive
clean-up and separation of hardware dependent and independent parts is
expected to happen after 6.0.

struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address

UARTs used to connect keyboards and not also PS/2 keyboards and only
return their package handle in case the keyboard is the preferred one
according to the OFW but otherwise still regardless of whether the
keyboard is used for stdin or not. This is simply achieved by looking
at the 'keyboard' alias and returning the corresponding package handle
in case it refers to a SCC/UART. This is change is done in order to
give the keyboard which the OFW or the user selected in OFW on boards
that support additional types of keyboards besides the RS232 ones also
preference in FreeBSD. It will be also used to determine on Sun AXi and
Sun AXmp boards whether a PS/2 or a RS232 is to be used as these are
sort of mutual exclusive there (see upcoming commit to uart_bus_ebus.c).
Note that Tatung AXi boards have the same issue but the former code
happened to already give the PS/2 keyboard preference by not identifying
the respective UART as keyboard system device there because the PS/2
keyboard node precedes the keyboard UART one in the OFW device tree of
these boards (which isn't the case for the Sun AXi).

the driver has unholy private knowledge of its great-*cgrandchildren.
The ACPI allocation routine lacked such knowledge when it tried to do
a default allocation for all descendants, rather than just its
immeidate children, so would access grandchild's ivar in an unsafe
way. This could lead to a panic when devices were present which had
no addresses setup by the BIOS, but which were later allocated in a
lazy manner via pci_alloc_map. As such, only do the default
allocation adjustments for immediate children. The manner that
acpi_sysres_find accesses the resource list, used later in
acpi_alloc_resource, is safe and proper so no additional test is
needed there.

use with syscons(4) on sparc64. It's based on the respective NetBSD
driver with some additional info (initialisation/hardware cursor)
obtained from the Xorg 'ati' driver and some ideas taken from
creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low-
end graphics chips in PCI-based sun4u machines and are used on-board
in e.g. Blade 100 and a couple of OEM products. Most if not all of
the Sun PGX add-on cards family (descriptions of the PGX32 are
conflicting but most say it's a Rage Pro) are also based on these
chips. Depending on the version of the OBP Mach64 cards destined for
use in i386 machines also work in sun4u machines.
The driver uses pixel mode with hardware acceleration as far as
syscons(4) currently permits on sparc64 so text mode is already
quite fast. The hardware cursor is used for the mouse pointer;
for one because this is a "restriction" induced in syscons(4) on
sparc64 by creator(4) and also because of issues with mapping
the aperture when used as a low-level early during boot. Due to
insufficiencies in the available documentation I didn't manage to
get mode switch work properly (sync problems), yet. So for now
this driver relies on the OBP having initialised a mode (as does
creator(4)). On all of the tested machines is even true when using
a serial console (and also not only when the OBP switched to a
serial console because no keyboard is present). In general however
the states the Mach64 chips are left in by the OBP vary a lot
depending on the version of the OBP. This e.g. includes the aperture
not being mapped in even when used as the console and the OBP just
barfing when asked to map it. The latter is also the reason for the
existence of this native driver in FreeBSD rather than taking an
OFW frambuffer approach.
Xorg is also happy to talk to these chips by mmap'ing them through
this driver. For some hardware configs like on the Blade 100 a fix
for the Xorg sparc64 MD bus code is however needed (added in version
6.8.2_2 of the xorg-server port).
The video driver font loading and saving methods are not implemented,
yet, as syscons(4) needs more work in that area to work viable on
sparc64.
With minor modifications machfb(4) would most likely also work on
powerpc, when #ifdef'ing the OFW and possibly implementing mode
setting probably also on the other archs. The latter is however
not very practible at the moment as it would conflict with vga(4).

- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.
- Some clean-up (remove unused/useless code, etc.).

We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).
On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.
Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.
Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.
What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.

Correcting the intpin value might be better off in the PCI code
via a quirk table but on the other hand gem(4) and hem(4) also
correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information
in a lot of places in the PCI code (i.e. whenever the value of the
intpin register is read from or written to the pci_devinfo of the
respective device) in order to do it the right way.

is termed somewhat confusing as it actually means don't manually adjust
the century in the driver).
- Add the MI part of interfacing the watchdog functionality of MK48Txx with
extended registers with watchdog(9). This is inspired by the SunOS/Solaris
drivers for the 'eeprom' devices also having watchdog support. I actually
expected this to work out of the box on Sun Exx00 machines with 'eeprom'
devices which have a 'watchdog-enable' property. On terminal count of the
the watchdog timer however only the MK48TXX_FLAGS_WDF bit rises but the
reset signal and the interrupt respectively (depending on whether the
MK48TXX_WDOG_WDS bit of the chip and the MK48TXX_WDOG_ENABLE_WDS flag
of the driver respectively is set) goes nowhere. Apparently passing the
reset signal on to the WDR line of the CPUs has to be enabled somewhere
else but we don't have documentation for the Exx00 specific controllers.
I decided to commit this nevertheless so it can be enabled in the eeprom(4)
front-end later in e.g. 6.0-STABLE without breaking the API. Besides the
Exx00 the watchdog part of the MK48Txx should also work on E250 and E450.

On reset, clear state flags and the msgout queue.
In NetBSD code to notify the upper layer (i.e. CAM in FreeBSD) on reset
was also added with this revision. This is believed to be not necessary
in FreeBSD and was not merged.
This makes ncr53c9x.c to be in sync with NetBSD up to rev. 1.114.
- Conditionalize the LSI64854 support on sbus(4) only instead of sbus(4)
and esp(4) as it's also required for the 'dma', 'espdma' and 'ledma'
busses/devices as well as the 'SUNW,bpp' device (printer port) which
all hang off of sbus(4).
- Add a driver for the 'dma', 'espdma' and 'ledma' (pseudo-)busses/
devices. These busses and devices actually represent the LSI64854 DMA
engines for the ESP SCSI and LANCE Ethernet controllers found on the
SBus of Ultra 1 and SBus add-on cards. With 'espdma' and 'ledma' the
'esp' and 'le' devices hang off of the respective DMA bus instead of
directly from the SBus. The 'dma' devices are either also used in this
manner or on some add-on cards also as a companion device to an 'esp'
device which also hangs off directly from the SBus. With the latter
variant it's a bit tricky to glue the DMA engine to the core logic of
the respective 'esp' device. With rev. 1.35 of sbus.c we are however
guaranteed that such a 'dma' device is probed before the respective
'esp' device which simplifies things a lot. [1]
- In the esp(4) SBus front-end read the part-unique ID code of Fast-SCSI
capable chips the right way. This fixes erroneously detecting some
chips as FAS366 when in fact they are not. Add explicit checks for the
FAS100A, FAS216 and FAS236 variants instead treating all of these as
ESP200. That way we can correctly set the respective Fast-SCSI config
bits instead of driving them out of specs. This includes adding the
FAS100A and FAS236 variants to the NCR53C9x core code. We probably
still subsume some chip variants as ESP200 while in fact they are
another variant which however shouldn't really matter as this will
only happen when these chips are driven at 25MHz or less which implies
not being able to run Fast-SCSI. [3]
- Add a workaround to the NCR53C9x interrupt handler which ignores the
stray interrupt generated by FAS100A when doing path inquiry during
boot and which otherwiese would trigger a panic.
- Add support for the 'esp' devices hanging off of a 'dma' or 'espdma'
busses or which are companions of 'dma' devices to esp(4). In case of
the variants that hang off of a DMA device this is a bit hackish as
esp(4) then directly uses the softc of the respective parent to talk
to the DMA engine. It might make sense to add an interface for this
in order to implement this in a cleaner way however it's not yet clear
how the requirements for the LANCE Ethernet controllers are and the
hack works for now. [2]
This effectively adds support for the onboard SCSI controller in
Ultra 1 as well as most of the ESP-based SBus add-on cards to esp(4).
With this the code for supporting the Performance Technologies SBS430
SBus SCSI add-on cards is also largely in place the remaining bits
were however omitted as it's unclear from the NetBSD how to couple
the DMA engine and the core logic together for these cards.

The Ralink RT2500 driver uses this API instead of NdisMIndicateReceivePacket().
Drivers use NdisMEthIndicateReceive() when they know they support
802.3 media and expect to hand their packets only protocols that want
to deal with that particular media type. With this API, the driver does
not manage its own NDIS_PACKET/NDIS_BUFFER structures. Instead, it
lets bound protocols have a peek at the data, and then they supply
an NDIS_PACKET/NDIS_BUFFER combo to the miniport driver, into which
it copies the packet data.
Drivers use NdisMIndicateReceivePacket() to allow their packets to
be read by any protocol, not just those bound to 802.3 media devices.
To make this work, we need an internal pool of NDIS_PACKETS for
receives. Currently, we check to see if the driver exports a
MiniportTransferData() method in its characteristics structure,
and only allocate the pool for drivers that have this method.
This should allow the RT2500 driver to work correctly, though I
still have to fix ndiscvt(8) to parse its .inf file properly.
Also, change kern_ndis.c:ndis_halt_nic() to reap timers before

The core console code checks this field when a console is added and
emits a warning if it's empty. In practice the warning is harmless for
uart(4), because the cn_name is filled in as soon as the device name is
known; which is when the device is enumerated.
To avoid the warning, to avoid possible complications caused by emitting
the warning without there (possibly) being a console selected yet and to
avoid complications when the UART isn't found during bus enumeration, we
just preset the cn_name field here to the name of the driver.

- Remove the old task threads from kern_ndis.c and reimplement them in

KeSetTargetProcessorDpc(), KeSetImportanceDpc() and KeFlushQueuedDpcs().
(This is the biggest change.)
- Fix a bug in NdisMInitializeTimer(): the k_dpc pointer in the
nmt_timer embedded in the ndis_miniport_timer struct must be set
to point to the DPC, also embedded in the struct. Failing to do
this breaks dequeueing of DPCs submitted via timers, and in turn
breaks cancelling timers.
- Fix a bug in KeCancelTimer(): if the timer is interted in the timer
queue (i.e. the timeout callback is still pending), we have to both
untimeout() the timer _and_ call KeRemoveQueueDpc() to nuke the DPC
that might be pending. Failing to do this breaks cancellation of
periodic timers, which always appear to be inserted in the timer queue.
- Make use of the nmt_nexttimer field in ndis_miniport_timer: keep a
queue of pending timers and cancel them all in ndis_halt_nic(), prior
to calling MiniportHalt(). Also call KeFlushQueuedDpcs() to make sure
any DPCs queued by the timers have expired.
- Modify NdisMAllocateSharedMemory() and NdisMFreeSharedMemory() to keep
track of both the virtual and physical addresses of the shared memory
buffers that get handed out. The AirGo MIMO driver appears to have a bug
in it: for one of the segments is allocates, it returns the wrong
virtual address. This would confuse NdisMFreeSharedMemory() and cause
a crash. Why it doesn't crash Windows too I have no idea (from reading
the documentation for NdisMFreeSharedMemory(), it appears to be a violation
of the API).
- Implement strstr(), strchr() and MmIsAddressValid().
- Implement IoAllocateWorkItem(), IoFreeWorkItem(), IoQueueWorkItem() and

fact that access to RR0 does not need a prior write to the register
index because the index always reverts to 0 after the indexed register
has been accessed.
Typically when a RR or WR is to accessed, one programs the index (which
is a write to the control register), followed by a read or write to the
actual indexed register (a read pr write to the same control register).
When this non-atomic sequence is interrupted after having written the
index and low-level console I/O is done in that situation, the write to
program the index will actually write to the indexed register and nuke
state. This almost always yields a wedge.
By not programming the index register and instead just reading from RR0,
the worst case scenario is non-fatal. For if we don't actually read from
RR0 but some other register we get an invalid status, which may lead us
to conclude that the transit data register is empty when it's not or that
the receive data register contains data when it doesn't. Hence, we may
lose an output character or get a sporadic input character, but given
the situation this is a non-issue.

here on in, if_ndis.ko will be pre-built as a module, and can be built
into a static kernel (though it's not part of GENERIC). Drivers are
created using the new ndisgen(8) script, which uses ndiscvt(8) under
the covers, along with a few other tools. The result is a driver module
that can be kldloaded into the kernel.
A driver with foo.inf and foo.sys files will be converted into
foo_sys.ko (and foo_sys.o, for those who want/need to make static
kernels). This module contains all of the necessary info from the
.INF file and the driver binary image, converted into an ELF module.
You can kldload this module (or add it to /boot/loader.conf) to have
it loaded automatically. Any required firmware files can be bundled
into the module as well (or converted/loaded separately).
Also, add a workaround for a problem in NdisMSleep(). During system
bootstrap (cold == 1), msleep() always returns 0 without actually
sleeping. The Intel 2200BG driver uses NdisMSleep() to wait for
the NIC's firmware to come to life, and fails to load if NdisMSleep()
doesn't actually delay. As a workaround, if msleep() (and hence
ndis_thsuspend()) returns 0, use a hard DELAY() to sleep instead).
This is not really the right thing to do, but we can't really do much
else. At the very least, this makes the Intel driver happy.
There are probably other drivers that fail in this way during bootstrap.
Unfortunately, the only workaround for those is to avoid pre-loading
them and kldload them once the system is running instead.
