Re-factor the console-related code into fdt_console.[ch]

Instead of requiring drivers to be explicit about their device memory
mapping requirements, move this decision into the fdt layer. This

for returning per-node bus_space handles.

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

mips/cavium: Simplify membars around interrupt establishment.

Previously I used xc_barrier to ensure the initialization of the
struct octeon_intrhand was witnessed on all CPUs before publishing
it, in order to avoid needing any barrier on the usage side to be
issued by the interrupt handler.

But there's no need to avoid atomic_load_consume at time of
interrupt: on MIPS it's the same as atomic_load_relaxed anyway, so
there's no additional memory barrier cost here.

to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

way (periodical update)

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Use DEVICE_COMPAT_EOL.

Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.

Remove "struct of_compat_data" and replace its usage with
"struct device_compatible_entry"; they are ABI-compatible.

Merge thorpej-cfargs2.

branches: 1.14.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Make sure we only attach to CN3xxx/CN5xxx.
Cleanup - mostly removing unused code.

Merge thorpej-cfargs2.

branches: 1.12.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

octeon_rnm.c: minor code formatting and grammar tweaks (NFC)

branches: 1.16.6;
octrnm(4): Raise delay on startup.

According to CN50XX-HRM-V0.99E and CN78XX-HM-0.99E:

The entropy is provided by the jitter of 125 of 128 free-running
oscillators XORed into a 128-bit LFSR. The LFSR accumulates entropy
over 81 cycles, after which it is fed into a SHA-1 engine.
[...]
The SHA-1 engine runs once every 81 cycles.
[...]
The hardware produces new 64-bit random number every 81 cycles.

The last sentence means that we only need to wait 81 cycles _between_
consecutive SHA-1 outputs (which isn't relevant anyway because we
reconfigure it into raw mode later), but the first two quotes might
mean that we need to wait 81+81 cycles for the _first_ output to be
produced on boot when running the self-test.

Now, in this case, the self-test is run with the LFSR unhooked, by
clearing the RNM_CTL_STATUS[ENT_EN] bit, so that SHA-1 is computed
from a known input -- this is really just paranoia to make sure that
_some_ functions of the device (which is conjured out of thin air at
a fixed virtual address, with no firmware bindings to guide us)
behave as we expect.

And it's not clear if it really does take 81+81 cycles for the first
SHA-1 output to appear when the LFSR isn't feeding into it anyway.
But experimentally, delay of 81+81 cycles seems to work whereas a
delay of only 81 cycles crashes.

rnd(9): Omit needless locks in various HWRNG drivers.

Now that the rnd(9) API guarantees serial callbacks, we can simplify
everything a bit more.

(Some drivers like hifn(4) and sun8icrypto(4) still use locks to
coordinate with other parts of the driver to submit requests to and
process responses from the device.)

rnd(9): Adjust IPL of locks used by rndsource callbacks.

These no longer ever run from hard interrupt context or with a spin
lock held, so there is no longer any need to have them at IPL_VM to
block hard interrupts. Instead, lower them to IPL_SOFTSERIAL.

Rename all Cavium Octeon device driver functions, structs etc from

Clean up Cavium Octeon device names. Rename devices from "octeon_foo"
to "octfoo" - this follows the naming conventions used by many other
MIPS CPUs.

CN70XX iobdma limit appears to be 128 words, so gather that many samples
as a time.
Gather the full 512 bytes of samples and process in a single call to
rnd_add_data_sync() - about 10% faster than 4 calls to rnd_add_data_sync().
Put sample buffer in the softc to save some stack usage.

Adjust entropy estimate for the Octeon.

We are hedging in serial and in parallel, and more conservative than
the Linux driver from Cavium seems to be, so although I don't know
exactly what the thermal jitter of the device is, this seems like a
reasonable compromise.

Change MII PHY read/write API from:

int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

of many different variations of the same theme.
- use #define's for CVMSEG addresses instead of magic numbers.
- use __BIT/__BITS/__SHIFTIN/__SHIFTOUT in most places, instead of
foo_SHIFT defines or (worse) shifting by magic numbers.

No functional changes.

Finish CPU core support for Octeon Cavium CN70XX:
- decode actual CPU name
- per CPU core reset logic (partially adapted from OpenBSD)
- handle Octeon 3 ioclock rate differences to other cores (from OpenBSD)

Finish rename of all Cavium Octeon device driver functions, structs etc from
"octeon_foo" to "octfoo" (missed octeon_uart + entries in iobus config).

Clean up Cavium Octeon device names. Rename devices from "octeon_foo"
to "octfoo" - this follows the naming conventions used by many other
MIPS CPUs.

Stop potential misuse of vendor names and USB vendor IDs in root hub
device and string descriptors.

Firstly: Few vendors have identical PCI-SIG vendor IDs and USB-IF vendor
IDs. As such, using the PCI vendor ID as a USB vendor ID may trample
on whomever is allocated that USB vendor ID.

Secondly: The vendor of the host controller hardware implementation has
little to nothing to do with our usbroothub implementation. Thus we
should not potentially associate any problems therewith to such third
party.

This change will result in root hubs being identified by USB Vendor ID
0x0000. Root hub vendor string will now be "NetBSD" (or, specifically:
ostype). Product ID (0x0000) and product strings remain unchanged.

Merge thorpej-cfargs2.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

branches: 1.4.2;
