arm64: allwinner: a64: enable Bluetooth On Pinebook

Pinebook has an RTL8723CS WiFi + BT chip, BT is connected to UART1
and uses PL4 as BT reset, PL5 as device wake GPIO, PL6 as host wake GPIO
the I2C controlling signals are connected to R_I2C bus.

Enable it in the device tree.

to attach.  more work with firmware and btattach will be required,
for the BT to be actually functional.

Add libnvmm, NetBSD's new virtualization API. It provides a way for VMM
software to effortlessly create and manage virtual machines via NVMM.

It is mostly complete, only nvmm_assist_mem needs to be filled -- I have
a draft for that, but it needs some more care. This Mem Assist should
not be needed when emulating a system in x2apic mode, so theoretically
the current form of libnvmm is sufficient to emulate a whole class of
systems.

Generally speaking, there are so many modes in x86 that it is difficult
to handle each corner case without introducing a ton of checks that just
slow down the common-case execution. Currently we check a limited number
of things; we may add more checks in the future if they turn out to be
needed, but that's rather low priority.

Libnvmm is compiled and installed only on amd64. A man page (reviewed by

Add a test to show a large number of MAC addresses cached in a bridge

(ozaki-r)

Fix that brconfig <bridge> (addr) can't show a large number of MAC addresses

The command shows only 256 addresses at maximum even if a bridge caches more
addresses.  It occurs because the kernel doesn't return an error if the command
passes a short buffer that can't store all cached addresses; the kernel fills
cached addresses as much as possible and returns it without telling that the
result is truncated.

Fix the issue by telling a required size of a buffer if a buffer passed from the
command is not enough, which lets the command retry with an enough buffer.

implement dumpsys() and friends for arm64.

this is almost a direct copy of the arm code, which is simply
as the basic structures about physical memory are the same
between arm and arm64.  the main change i made was to use
the direct map instead of a virtual dump page that is remapped
to whatever physical page is being dumped.

i also changed the existing cpu_kcore_hdr_t to include the
missing number of ram segments.

note that this is not a complete solution for crash dumps yet,
as the libkvm code needs some work.  i'm fairly positive that
this side is correct, as i can see the data i expect to see,
but libkvm's _kvm_kvtop() function returns garbage so far.

there is no "minidump" support here yet, ala amd64, but we
probably want it eventually.

Workaround PN533 USB descriptor corruption

During normal operation, the PN533 chip may corrupt its USB configuration,

Since the descriptors are documented to be immutable, we can work around
the problem by providing hard-coded descriptors instead of pulling them
from the device.

Userland implementation such as NFC tools' libnfc use the same approach,
but this kernel quirk is still necessary so that the device can be
attached on reboot, after its USB descriptors got corrupted.

It is made of an MI frontend, to which MD backends can be plugged. One

We install

/usr/include/dev/nvmm/nvmm.h

And the kernel module. For now, the only architecture where we do that

Disable x87 implementations of sin, cos, tan.

The x87 hardware uses a bad approximation to pi for argument

Fix up libm tests.

- Fix up last few digits of a lot of known-answer tests.

  Confirmed with GNU mpfr to 200 bits of precision and cross-checked
  with whatever libm Ubuntu ships with.

- Test relative error, not absolute error.

- Set bounds in terms of *_EPSILON, not magic numbers.

  *_EPSILON is twice the largest relative error of a correctly
  rounded operation, and equal to the largest relative error of an
  operation with up to 1ulp error.

  Most of the operations we're testing are not correctly rounded, but
  they ought to be no more than 1ulp away.  For the few cases where
  that's not a priori clear (like comparing cbrt and pow(x, 1/3)),
  use twice *_EPSILON to allow some leeway.

- Write the success condition positively as error <= eps.

  This comes out false if the result is a NaN, meaning failure.  In
  contrast, if we write error > eps for the _failure_ condition, then
  if the result is a NaN, it will also come out false, but meaning
  success, which is not what we want.

- Fix the trigonometric test cases near bad spots.

  sin(pi - d) for nonzero d is not zero; it is d + O(d^3).  pi is not
  a floating-point number, so these results should be approximately
  the nonzero error of our approximation to pi.  Likewise with
  cos(pi/2 - d) and tan(pi + d).

  (Yes, I know the sin _function_ is ill-conditioned near pi so you
  shouldn't pass approximate inputs near there, but that's separate
  from whether a sin _implementation_ gives an answer that is wrong
  by quintillions of ulps.)

  Since on x86 (i386 and amd64 alike) we currently use x87 hardware
  trigonometric instructions, which are bad, these are marked xfail
  on x86 for now until we switch to software implementations (coming
  soon to a repository near you).

- Use %.8g, %.17g, %.35g to print float, double, long double in failures.

  This should be enough to identify the problematic outputs and/or
  reproduce the computation, even if long double is binary128 with
  115 bits of precision.

If there are any new libm test failures after this, tell me what
architecture you're on and send me the atf output and I'll try to
figure it out.

Remove a wrong assertion in ifaref

-

Doing ifref on an ifa with IFA_DESTROYING is not a problem; the reference should
be dropped during the destruction of the ifa.

-

Use atomic operations for ifa_refcnt

-

Avoid a dangling pointer during rt_replace_ifa

-

Avoid double rt_replace_ifa on rtrequest1(RTM_ADD)

Some callers of rtrequest1(RTM_ADD) adjust rt_ifa of an rtentry created by
rtrequest1 that may change rt_ifa (in ifa_rtrequest) with another ifa that is
different from requested one.  It's wasteful and even worse introduces a race
condition.  rtrequest1 should just use a passed ifa as is if a caller hopes so.

-

Use rt_update framework on updating a rtentry

(martin)

Correct background check file for fixed curses behaviour.
This fixes lib/53676.

(blymn)

Update man page to document z-axis emulation.

(blymn)

Add double finger scroll feature.  If the detected width is between a
defined range then report y movement as z-axis.  Effectively emulating
a mouse scroll wheel.

(blymn)

Fix clamping of deltas so it works for both positive and negative deltas.

(blymn)

- make the build depend upon the BASE-VER file.
- workaround a problem only see with -O2 in ipa-inline.c: it can't
  convince itself that an integer underflow can't happen.

(mrg)

add rc.d/dhcpd6

(plunky)

Restore the length check of a sockaddr passed from userland at udp6_output

A sockaddr with invalid length could be passed to the network stack resulting in
a kernel panic like this:

put a bunch of the kvm_read + warn on failure code into a macro that
describes more about what failed.  now errors tell you which actual
variable was being requested instead of simply saying "not yours".

tested on amd64 as working.  written for arm64 testing.

(mrg)

add support to detect the 3 vmware GPT partition types:

- VMKcore (dump partition)
- VMFS
- VMware reserved

this enables vmkcore partitions for netbsd swap or dump, as well
as naming all of them.

Fix use after RECLAIM in PUFFS filesystems

From hannken@

When puffs_cookie2vnode() misses an entry and vrele() it operations
puffs_vnop_reclaim() and puffs_vnop_fsync() get called with a VNON
vnode.

Do not notify the server in this case as the cookie is stale.

(manu)

Match the right MACHINE_ARCHes for GENERIC.

(skrll)

Get rid of hard coded disk names and use sysctl hw.disknames
instead.

(martin)

When refactoring interface drivers after netbsd-4, the SIOCINITIFADDR
ioctl was passed through ifioctl_common, because the case falls through
to the SIOCSIFFLAGS case. The common handler however doesn't implement
SIOCINITIFADDR, so an attempt to configure plip always failed with ENOTTY.

(mlelstv)

Fix typo s/fron/from/

From dfive on freenode, thanks!

(maya)

For "unknown" sets (should only happen for pkgsrc.tgz), always use
.tgz suffix.

(martin)

ICC_PMR_EL1 has different encoding than IPRIORITYR. Not 100% sure that this is correct yet, but it works with both RK3399 and QEMU.

(jmcneill)

Revert previous - local merge mishap

(martin)

Sort options.

(wiz)

Fix xref.

(wiz)

regenerate everything for GCC 6.5.

sh3eb and sh3el had a problem wtih libstdc++ i had to work around for now.

(mrg)

GCC 6.5 ios_failure.cc needs to be compiled with cxx mode.

(mrg)

Make it compilable with gcc

(martin)

Merge in VIRT now that qemu in pkgsrc can support it (missed in previous
commit)

(skrll)

Merge in VIRT now that qemu in pkgsrc can support it

(skrll)

Decode Boot Graghics Resource Table (BGRT).

(msaitoh)

Suggest to remove lfs_ stubs on a major bump.
they're deprecated, ioctl is used instead.

(maya)

Decode PCI Enhanced Allocation.

(msaitoh)

Add missing mutex pn->pn_sizemtx lock in puffs_vnop_open()

puffs_vnop_open() calls flushvncache(), which calls dosetattr()
if pn->pn_stat has PNODE_METACACHE_MASK. In that case, the lock
on pn->pn_sizemtx is mandatory and asserted.

(manu)

initialise the kvm errbuf so that if an error occurs, but the
internal _kvm_*err() functions aren't called, stack garbage is
not reported as an error string.

call _kvm_err() if _kvm_kvatop() fails.  now the above is not
triggered anymore :-)

(mrg)

Only add GENERIC to earmv6 and earmv7 builds
