9919dec83c if_arge: fix up TX workaround; add TX/RX requirements for busdma; add stats
The early ethernet MACs (I think AR71xx and AR913x) require that both
TX and RX require 4-byte alignment for all packets.

The later MACs have started relaxing the requirements.

For now, the 1-byte TX and 1-byte RX alignment requirements are only for
the QCA955x SoCs.  I'll add in the relaxed requirements as I review the
datasheets and do testing.

* Add a hardware flags field and 1-byte / 4-byte TX/RX alignment.
* .. defaulting to 4-byte TX and 4-byte RX alignment.
* Only enforce the TX alignment fixup if the hardware requires a 4-byte
  TX alignment.  This avoids a call to m_defrag().
* Add counters for various situations for further debugging.
* Set the 1-byte and 4-byte busdma alignment requirement when
  the tag is created.

This improves the straight bridging performance from 130mbit/sec
to 180mbit/sec, purely by removing the need for TX path bounce buffers.

The main performance issue is the RX alignment requirement and any RX
bounce buffering that's occuring.  (In a local test, removing the RX
fixup path and just aligning buffers raises the performance to above
400mbit/sec.

In theory it's a no-op for SoCs before the QCA955x.

Tested:

* QCA9558 SoC in AP135 board, using software bridging between arge0/arge1.

42d17d369b Add Ubiquiti EdgeRouter Lite (ERL) kernel config file
The ERL is a fairly cheap (~$100 USD) and readily available dual core
MIPS64 device so it makes a useful MIPS reference platform.

This is based in part on the kernel config generated by the mkerlimage
script from http://rtfm.net/FreeBSD/ERL/.

27b3a39a8f Update the AP135 reference design flash layout to be more useful.
* Shuffle the kernel to be at the beginning
* Give the kernel 2mb, the rootfs 6mb, and 'mib0' the rest
* put the cfg parition just before the ART calibration data for the
  wifi part in the SoC
* .. and make sure ART points to the right 64k region.

I've updated the freebsd-wifi-build wiki the instructions on using this.

If someone has an AP135 with 8MB SPI flash then this won't work; everything
minus the big mib0 partition is just a bit over 8MB.  Come see me if this
ever happens (you'll likely just have to shrink the rootfs and the kernel
a little in order to make it fit.)

9f86aba61c Exploit r288122 to address a cosmetic issue. Since PV chunk pages don't
belong to a vm object, they can't be paged out.  Since they can't be paged
out, they are never enqueued in a paging queue.  Nonetheless, passing
PQ_INACTIVE to vm_page_unwire() creates the appearance that these pages
are being enqueued in the inactive queue.  As of r288122, we can avoid
this false impression by passing PQ_NONE.

cff8c6f2d1 Add support for weak symbols to the kernel linkers. It means that
linkers no longer raise an error when undefined weak symbols are
found, but relocate as if the symbol value was 0.  Note that we do not
repeat the mistake of userspace dynamic linker of making the symbol
lookup prefer non-weak symbol definition over the weak one, if both
are available.  In fact, kernel linker uses the first definition
found, and ignores duplicates.

Signature of the elf_lookup() and elf_obj_lookup() functions changed
to split result/error code and the symbol address returned.
Otherwise, it is impossible to return zero address as the symbol
value, to MD relocation code.  This explains the mechanical changes in
elf_machdep.c sources.

The powerpc64 R_PPC_JMP_SLOT handler did not checked error from the
lookup() call, the patch leaves the code as is (untested).

610141cebb Add stack_save_td_running(), a function to trace the kernel stack of a
running thread.

It is currently implemented only on amd64 and i386; on these
architectures, it is implemented by raising an NMI on the CPU on which
the target thread is currently running. Unlike stack_save_td(), it may
fail, for example if the thread is running in user mode.

This change also modifies the kern.proc.kstack sysctl to use this function,
so that stacks of running threads are shown in the output of "procstat -kk".
This is handy for debugging threads that are stuck in a busy loop.

713841afb2 Add two new pmap functions:
vm_offset_t pmap_quick_enter_page(vm_page_t m)
void pmap_quick_remove_page(vm_offset_t kva)

These will create and destroy a temporary, CPU-local KVA mapping of a specified page.

Guarantees:
--Will not sleep and will not fail.
--Safe to call under a non-sleepable lock or from an ithread

Restrictions:
--Not guaranteed to be safe to call from an interrupt filter or under a spin mutex on all platforms
--Current implementation does not guarantee more than one page of mapping space across all platforms. MI code should not make nested calls to pmap_quick_enter_page.
--MI code should not perform locking while holding onto a mapping created by pmap_quick_enter_page

The idea is to use this in busdma, for bounce buffer copies as well as virtually-indexed cache maintenance on mips and arm.

NOTE: the non-i386, non-amd64 implementations of these functions still need review and testing.

8954a9a4e6 Add the atomic_thread_fence() family of functions with intent to
provide a semantic defined by the C11 fences with corresponding
memory_order.

atomic_thread_fence_acq() gives r | r, w, where r and w are read and
write accesses, and | denotes the fence itself.

atomic_thread_fence_rel() is r, w | w.

atomic_thread_fence_acq_rel() is the combination of the acquire and
release in single operation.  Note that reads after the acq+rel fence
could be made visible before writes preceeding the fence.

atomic_thread_fence_seq_cst() orders all accesses before/after the
fence, and the fence itself is globally ordered against other
sequentially consistent atomic operations.

c37904e8ba Reshuffle all of the DDR flush operations into a single switch/mux,
and start teaching subsystems about it.

The Atheros MIPS platforms don't guarantee any kind of FIFO consistency
with interrupts in hardware.  So software needs to do a flush when it
receives an interrupt and before it calls the interrupt handler.

There are new ones for the QCA934x and QCA955x, so do a few things:

* Get rid of the individual ones (for ethernet and IP2);
* Create a mux and enum listing all the variations on DDR flushes;
* replace the uses of IP2 with the relevant one (which will typically
  be "PCI" here);
* call the USB DDR flush before calling the real USB interrupt handlers;
* call the ethernet one upon receiving an interrupt that's for us,
  rather than never calling it during operation.

Tested:

* QCA9558 (TP-Link archer c7 v2)
* AR9331 (Carambola 2)

TODO:

* PCI, USB, ethernet, etc need to do a double-check to see if the
  interrupt was truely for them before doing the DDR.  For now I
  prefer "correct" over "fast".

b14a705362 Add initial support for the TP-Link Archer C7 v2.
The SoC, the flash, the ethernet ports and ethernet switch all work.
The USB works.

The 11ac PCIe NIC internally is at least seen by the PCIE RC, but
I haven't tried using it yet.  There's no driver and I haven't
yet swapped it out for a non-11ac chip.

The on-chip 2GHz wifi works, but there are some data errors that
get thrown up in STA mode when scanning.  I have a feeling I have
to finish the DDR flush code out and have it run correctly on the
shared interrupts; that'll take a bit of time to get right.

But if you're after an updated piece of hardware, the Archer C7 v2
is certainly there, and you can replace the 11ac NIC with a 3x3
Atheros PCIe device (eg AR9380, AR9390, AR9580, etc) and it'll
"just work".

d1b06863fb Huge cleanup of random(4) code.
* GENERAL
- Update copyright.
- Make kernel options for RANDOM_YARROW and RANDOM_DUMMY. Set
  neither to ON, which means we want Fortuna
- If there is no 'device random' in the kernel, there will be NO
  random(4) device in the kernel, and the KERN_ARND sysctl will
  return nothing. With RANDOM_DUMMY there will be a random(4) that
  always blocks.
- Repair kern.arandom (KERN_ARND sysctl). The old version went
  through arc4random(9) and was a bit weird.
- Adjust arc4random stirring a bit - the existing code looks a little
  suspect.
- Fix the nasty pre- and post-read overloading by providing explictit
  functions to do these tasks.
- Redo read_random(9) so as to duplicate random(4)'s read internals.
  This makes it a first-class citizen rather than a hack.
- Move stuff out of locked regions when it does not need to be
  there.
- Trim RANDOM_DEBUG printfs. Some are excess to requirement, some
  behind boot verbose.
- Use SYSINIT to sequence the startup.
- Fix init/deinit sysctl stuff.
- Make relevant sysctls also tunables.
- Add different harvesting "styles" to allow for different requirements
  (direct, queue, fast).
- Add harvesting of FFS atime events. This needs to be checked for
  weighing down the FS code.
- Add harvesting of slab allocator events. This needs to be checked for
  weighing down the allocator code.
- Fix the random(9) manpage.
- Loadable modules are not present for now. These will be re-engineered
  when the dust settles.
- Use macros for locks.
- Fix comments.

  localised trickery is used to manufacture a 128-bit 0ULLL.

* src/sys/dev/random/unit_test.c src/sys/dev/random/unit_test.h

  it against blatant by compress/hashing.

5caa65ca2d The add_bounce_page() function can be called when loading physical
pages which pass a NULL virtual address. If the BUS_DMA_KEEP_PG_OFFSET
flag is set, use the physical address to compute the page offset
instead. The physical address should always be valid when adding
bounce pages and should contain the same page offset like the virtual
address.

517aea2c14 Start enabling the available GPIO pins on the Carambola 2.
The carambola2 exposes all the gpio pins, but some are reserved for
core functions (eg usb, ethernet, etc.) Others are configured by default
to be available as normal GPIO pins to do interesting things with.

GPIO 18->23 is the I2S, SLIC and SPDIF device pins, but none of those
are currently used.  So, just allow those to show up.

Tested:

* AR9344, Carambola 2
* (.. bitbang SPI to an Adafruit LCD via libgpio, because FreeBSD could
  do with more shiny output devices that aren't network interfaces.)

TODO:

There are some other pins aren't currently included here, but should be.
The LED pins are for the internal switch inside the AR9344.

* GPIO 0+1 are "LED0 + LED1", but they're tied to high for bootstrapping.
* GPIO 13-17 are "LED2..7", but they're tied (H, L, L, L, H) for bootstrapping.
* GPIO 11 and 12 are UART RTS/CTS or I2S; but GPIO 12 is tied L for bootstrap.

405ada37fb Add support for the uart classes to set their default register shift value.
This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.

This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

The MAC addresses were totally wrong. They're like the DIR-625C1 - at
0x1ffe0004 and 0x1ffe0018. They're however stored as text strings.
The ath0 MAC address is also not set, even though the calibration
partition is valid.

So, pick the board address / first MAC as the ath0 MAC, and derive
arge0/arge1 from that.  That way they're hopefully unique enough
for people with multiple devices.

b7d7ad0b90 Begin moving support for board MAC addresses over to being explicitly defined.
A lot of these dinky atheros based MIPS boards don't have a nice, well,
anything consistent defining their MAC addresses for things.

The Atheros reference design boards will happily put MAC addresses
into the wifi module calibration data like they should, and individual
ethernet MAC addresses into the calibration area in flash.
That makes my life easy - "hint.arge.X.eeprommac=<addr>" reads from
that flash address to extract a MAC, and everything works fine.

However, aside from some very well behaved vendors (eg the Carambola 2
board), everyone else does something odd.

eg:

* a MAC address in the environment (eg ubiquiti routerstation/RSPRO)
   that you derive arge0/arge1 MAC addresses from.
* a MAC address in flash that you derive arge0/arge1 MAC addresses from.
* The wifi devices having their own MAC addresses in calibration data,
  like normal.
* The wifi devices having a fixed, default or garbage value for a MAC
  address in calibration data, and it has to be derived from the
  system MAC.

So to support this complete nonsense of a situation, there needs to be
a few hacks:

* The "board" MAC address needs to be derived from somewhere and squirreled
  away.  For now it's either redboot or a MAC address stored in calibration
  flash.

* Then, a "map" set of hints to populate kenv with some MAC addresses
  that are derived/local, based on the board address.  Each board has
  a totally different idea of what you do to derive things, so each
  map entry has an "offset" (+ve or -ve) that's added to the board
  MAC address.

* Then if_arge (and later, if_ath) should check kenv for said hint and
  if it's found, use that rather than the EEPROM MAC address - which may
  be totally garbage and not actually work right.

In order to do this, I've undone some of the custom redboot expecting
hacks in if_arge and the stuff that magically adds one to the MAC
address supplied by the board - instead, as I continue to test this
out on more hardware, I'll update the hints file with a map explaining
(a) where the board MAC should come from, and (b) what offsets to use
for each device.

The aim is to have all of the tplink, dlink and other random hardware
we run on have valid MAC addresses at boot, so (a) people don't get
random B:S:Dx:x ethernet MACs, and (b) the wifi MAC is valid
so it works rather than trying to use an invalid address that
actually upsets systems (think: multicast bit set in BSSID.)

Tested:

* TP-Link TL_WDR3600 - subsequent commits will add the hints map
  and the if_ath support.

TODO:

* Since this is -HEAD, and I'm all for debugging, there's a lot of
  printf()s in here.  They'll eventually go under bootverbose.
* I'd like to turn the macaddr routines into something available
  to all drivers - too many places hand-roll random MAC addresses
  and parser stuff.  I'd rather it just be shared code.
  However, that'll require more formal review.
* More boards.

753370121e Add GPIO function mux configuration for AR934x SoCs.
The AR934x (and maybe others in this family) have a more complicated
GPIO mux.  The AR71xx just has a single function register for a handful
of "GPIO or X" options, however the AR934x allows for one of roughly
100 behaviours for each GPIO pin.

So, this adds a quick hints based mechanism to configure the output
functions, which is required for some of the more interesting board
configurations.  Specifically, some use external LNAs to improve
RX, and without the MUX/output configured right, the 2GHz RX side
will be plain terrible.

It doesn't yet configure the "input" side yet; I'll add that if
it's required.

Tested:

* TP-Link TL-WDR3600, testing 2GHz STA/AP modes, checking some
  basic RX sensitivity things (ie, "can I see the AP on the other
  side of the apartment that intentionally has poor signal reception
  from where I am right now.")

bbe493ec23 Modify the if_arge code to use a /fixed/ media mode when it's configured.
Otherwise, the initial media speed would change if a PHY is hooked up,
sending PHY speed notifications.  For the AP135 at least, the RGMII
PHY has a static speed/duplex configured and if the PHY plumbing
attaches the PHY to the if_arge interface, the first link speed change
from 1000/full will set the MAC to something that isn't useful.

This shouldn't affect any other platforms - everything I looked at is
using hard-coded speed/duplex as static, as they're facing a switch
with no PHY attached.

1d556f272c Fix both arge0 and arge1 to work correctly on the AP135.
* Force the arge0 interface to not use a PHY for speed negotiation
  for now.  It'd be nice to do it, but right now the RGMII interface
  to the switch needs to stay at 1000/full in order to match what
  the switch side of the port is programmed as.

  So until that's all sorted out, disconnect arge0 from the PHY
  and leave it at fixed at 1000/full.

  I noticed this when I tried using a busted ethernet cable that
  forced the PHY to negotiate 100/full.  The switch was fine and
  it negotiated to 100/full, but then arge0 saw the link update
  and set the speed to 100/full when the switch side of that
  hook up was set to 1000/full.  Tsk.

* When using argemdio, the mdio device resets and initialises
  the MAC, /not/ the arge_attach (or, as I discovered, arge_init.)
  So arge1 wasn't being fully initialised and thus no traffic
  would ever flow.

  So until I tidy up that mess, just create an argemdio bus for
  arge1.  It's totally fine; it won't do anything or find anything
  attached to it.

* both USB 2.0 EHCI controllers
* on-board 2GHz 3x3 wifi (the other variant has 2GHz/5GHz wifi on-chip);

TODO:

* There's an interrupt mux hooking up devices to IP2 and IP3 - but it's
  not a read-and-clear or write-to-clear register.  So, trying to use it
  naively like I have been ends up with massive interrupt storms.
  For now the things that share those interrupts can just take them as
  shared interrupts and try to play nice.

* There's two PCIe root complexes /and/ one of them can actually be
  a PCIe device endpoint.  Yes, you heard right.  I have to teach the
  AR724x PCIe bridge code to handle multiple instances with multiple
  memory/irq regions, and then there'll be RC support, but EP support
  isn't on my TODO list.

206f09eb46 Do not qualify the mcontext_t *mcp argument for set_mcontext(9) as
const.  On x86, even after the machine context is supposedly read into
the struct ucontext, lazy FPU state save code might only mark the FPU
data as hardware-owned.  Later, set_fpcontext() needs to fetch the
state from hardware, modifying the *mcp.

The set_mcontext(9) is called from sigreturn(2) and setcontext(2)
implementations and old create_thread(2) interface, which throw the
*mcp out after the set_mcontext() call.

bdb9ab0dd9 Factor out duplicated code from dumpsys() on each architecture into generic
code in sys/kern/kern_dump.c. Most dumpsys() implementations are nearly
identical and simply redefine a number of constants and helper subroutines;
a generic implementation will make it easier to implement features around
kernel core dumps. This change does not alter any minidump code and should
have no functional impact.

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

87a2f105ee Make the apb.c code optional behind ar71xx_apb rather than standard.
The QCA955x has more mux interrupts going on - and the AR934x actually does,
but I cheated and assigned wlan and pcie to the same interrupt line.
They are, there's just a status register mux that I should've been using.

Luckily this isn't too bad a change in itself - almost all of the
Atheros MIPS configurations use a _BASE file to inherit from.
Except PB92, which I should really fix up at some point.

The AR934x will use the legacy apb for now until I write its replacement.

The QCA955x SoC I'm doing bring-up on will have a separate qca955x_apb.c
implementation that includes hooking into IP2/IP3 and doing further
interrupt demuxing as appropriate.

e090d1f591 Add an APB base/size for the QCA955X for an upcoming QCA955x specific
APB mux.

It's larger than the AR71xx because it needs to replace the nexus
for some devices (notably wifi) and the wifi driver (if_ath_ahb.c)
reads the SPI data directly at early boot whilst it's memory mapped
in.

I'm eventually going to rip it out and replace it with a firmware
interface similar to what exists for the if_ath_pci.c path -
something early on (likely something new that I'll write) will
suck in the calibration data into a firmware API blob and that'll
be accessed from if_ath_ahb.c.

But, one thing at a time.

c69537d018 Add a GPIO output mux configuration method.
The AR934x and later (which will turn up eventually) have a new GPIO
output configuration option - a real MUX rather than a "GPIO or this
function."

For now I'm squirreling it away in the CPU code just so it's done -
I may move this to the GPIO layer later.

Specifically, this is required for setting up some boards that have
external receive side LNA (low noise amplifier) that gets switched on/off
by the on-chip wireless MAC.  If we don't add this support for those
boards then we'll end up with really poor performance.

(I don't yet have one of those APs, but it'll likely show up in a week.)

d866a563d4 The physical memory allocator supports the use of distinct free lists for
managing pages from different address ranges.  Generally speaking, this
feature is used to increase the likelihood that physical pages are
available that can meet special DMA requirements or can be accessed through
a limited-coverage direct mapping (e.g., MIPS).  However, prior to this
change, the configuration of the free lists was static, i.e., it was
determined at compile time.  Consequentally, free lists could be created
for address ranges that held no actual pages, for example, on 32-bit MIPS-
based systems with 512 MB or less of physical memory.  This change makes
the creation of the free lists dynamic, i.e., it is based on the available
physical memory at boot time.

On 64-bit x86-based systems with 64 GB or more of physical memory, create
free lists for managing pages with physical addresses below 4 GB.  This
change is to address reported problems with initializing devices that
require the allocation of physical pages below 4 GB on some systems with
128 GB or more of physical memory.

08fca7a56b Add some new modes to OpenCrypto. These modes are AES-ICM (can be used
for counter mode), and AES-GCM.  Both of these modes have been added to
the aesni module.

Included is a set of tests to validate that the software and aesni
module calculate the correct values.  These use the NIST KAT test
vectors.  To run the test, you will need to install a soon to be
committed port, nist-kat that will install the vectors.  Using a port
is necessary as the test vectors are around 25MB.

All the man pages were updated.  I have added a new man page, crypto.7,
which includes a description of how to use each mode.  All the new modes
and some other AES modes are present.  It would be good for someone
else to go through and document the other modes.

A new ioctl was added to support AEAD modes which AES-GCM is one of them.
Without this ioctl, it is not possible to test AEAD modes from userland.

Add a timing safe bcmp for use to compare MACs.  Previously we were using
bcmp which could leak timing info and result in the ability to forge
messages.

Add a minor optimization to the aesni module so that single segment
mbufs don't get copied and instead are updated in place.  The aesni
module needs to be updated to support blocked IO so segmented mbufs
don't have to be copied.

We require that the IV be specified for all calls for both GCM and ICM.
This is to ensure proper use of these functions.
