viac7temp(4): rewrite temperature sensor to read value from MSR instead of using
documented cpuid instruction and eax register.

This approach is adapted from linux via-cputemp.c, no official documentation is
currently available. However, msr value seems to work on all tested CPUs while
documented cpuid instruction typically reports 0, even for my C7-D CPU.
msr value seems to have temperature in Celsius in lower 24-bits without fraction
(thus "msr & 0xffffff;" is used).

Tested on my personal systems based on CPUs below (i386 and amd64):
C7-D 1.6GHz (i386 only), Nano X2 L4350E, Nano X2 U4300, U2300 Nano, KX-U6580.
Also got one response via email which was based on Nano X2 L4050 (VE-900).
Nano reports independent values for each core.
KX-U6580 seems to show the same value for all cores but more testing is needed.

Since it works on amd64 capable CPUs, adding driver to GENERIC kernel config.
Also moving viac7temp man page to x86 instead of i386 (with updates).
In theory the change should add support for all VIA Nano CPUs and Zhaoxin CPUs
at least up to KX-6000(G) series.

In the future I may need to introduce amd64 kernel module as well.

Plan to pullup to at least netbsd-10.

x86: Support EFI runtime services.

This creates a special pmap, efi_runtime_pmap, which avoids setting
PTE_U but allows mappings to lie in what would normally be user VM --
this way we don't fall afoul of SMAP/SMEP when executing EFI runtime
services from CPL 0. SVS does not apply to the EFI runtime pmap.

The mechanism is intended to work with either physical addressing or
virtual addressing; currently the bootloader does physical addressing
but in principle it could be modified to do virtual addressing
instead, if it allocated virtual pages, assigned them in the memory
map, and issued RT->SetVirtualAddressMap.

Not sure pmap_activate_sync and pmap_deactivate_sync are correct,
need more review from an x86 wizard.

If this causes fallout, it can be disabled temporarily without
reverting anything by just making efi_runtime_init return immediately
without doing anything, or by removing options EFI_RUNTIME.

amd64-only for now pending type fixes and testing on i386.

This exists for compatibility with a Linux interface which was apparently

At this point it is highly unlikely this 1999 device still has users,

Proposed on tech-kern a month ago.

Retire "le* at pci?" from the shipped kernel configs:
- If the config had both an le@pci and a pcn, simply remove le@pci

- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.

The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.

Remove FDDI support.

Remove filemon(4).

Discussed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2020/01/13/msg025938.html

This was never (intentionally) enabled by default, and the design has
some shortcomings. You can get mostly the same results with ktrace,
as in usr.bin/make/filemon/filemon_ktrace.c which is now used instead
of filemon for make's meta mode.

If applications require higher performance than ktrace, or nesting
that ktrace doesn't support, we might consider adding something back
into the vfs system calls themselves, without hijacking the syscall
table. (Might want a more reliable output format too, e.g. one that
can handle newlines in file names.)

Remove support for vm86 on i386. It is bug-friendly, and there is no point
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.

vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.

Remove compat_ibcs2 from i386. After a discussion on port-vax, it turns
out that compat_ibcs2 does not implement the iBCS2 standard - which is
x86-specific - but rather SVR3. Our real iBCS2 implementation was a
mixture of compat_ibcs2 and compat_svr4, and was only partial. Keeping
support for this in i386 is totally irrelevant today. I also asked on
port-i386 but didn't wait long.

The main issue is that compat_ibcs2 should have been called compat_svr3.
But CVS does not support renaming files, and moving things around is both
painful and tiring, even more so when no one seems to be interested in
doing this work or in the feature at all. For now compat_ibcs2 is available
on Vax and will stay, until someone (not me) cleans it up.

We actually have a big problem: the fileassocs are never deleted.
Therefore, if a user generates a lot of buggy binaries and launches them

disk). Which means that a user can too easily put the kernel under memory
pressure.

Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
cpu_configure(), this enables FP emulation for a 486SX.
(for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.

Adding ibmcd(4), a device driver for the IBM 4810 BSP cash drawer port as

not.

Import NPF - a packet filter. Some features:

- Designed to be fully MP-safe and highly efficient.

- Tables/IP sets (hash or red-black tree) for high performance lookups.

- Stateful filtering and Network Address Port Translation (NAPT).
Framework for application level gateways (ALGs).

- Packet inspection engine called n-code processor - inspired by BPF -
supporting generic RISC-like and specific CISC-like instructions for
common patterns (e.g. IPv4 address matching). See npf_ncode(9) manual.

- Convenient userland utility npfctl(8) with npf.conf(8).

NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.

PR# kern/42139: ACPI WMI: new driver

Import acpiwmi(4) from Jukka Ruohonen. From the PR:

Attached is a driver that implements ACPI WMI API:

http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx

The WMI is used to provide a generic interface for OEMs to use certain
platform/laptop-specific additions to the standard ACPI in a somewhat
portable way. These can be hotkeys for additional buttons, different event
handlers (wireless kill switch, lid switch, etc.), and so on. At least HP
and Acer use it by default nowadays.

The benefit of this interface would be portability. For an example, instead
of hpqlb(4) that works only with certain HP models, we could have a generic
HP WMI-driver that should work in theory across all HP laptops. On many new
laptops WMI may also be the only way to access laptop/manufacturer-specific
features.

elanpex(4) is for PCI exception reporting. I've already found some

elanpar(4) protects the kernel text from writes by the CPU and by
PCI bus masters. As you might guess, this is not compatible with
setting breakpoints using a debugger; detach the device using
'drvctl -d elanpar0' before you try to set breakpoints. In the

write-protection.
