240429103c Rename ofwpci.c to ofw_pcib.c
It's a class0 driver that implements some pcib methods and creates
a pci bus as its children.
The "ofw_pci" name will be used by a new driver that will be a subclass
of the pci bus.
No functional changes intended.

af366d353b amd64: implement strlen in assembly
The C variant in libkern performs excessive branching to find the
non-zero byte instead of using the bsfq instruction. The same code
patched to use it is still slower than the routine implemented here
as the compiler keeps neglecting to perform certain optimizations
(like using leaq).

On top of that the routine can is a starting point for copyinstr
which operates on words instead of bytes.

Tested with glibc test suite.

9aafc7c052 [PowerPC] [MIPS] Implement 32-bit kernel emulation of atomic64 operations
This is a lock-based emulation of 64-bit atomics for kernel use, split off
from an earlier patch by jhibbits.

This is needed to unblock future improvements that reduce the need for
locking on 64-bit platforms by using atomic updates.

The implementation allows for future integration with userland atomic64,
but as that implies going through sysarch for every use, the current
status quo of userland doing its own locking may be for the best.

230754ccca Add support for BERI statcounters.
BERI stands for Bluespec Extensible RISC Implementation, based on MIPS.

BERI has not implemented standard MIPS perfomance monitoring counters,
instead it provides statistical counters.

BERI statcounters have a several limitations:
- They can't be written
- They don't support start/stop operation
- None of hardware interrupt is provided on a counter overflow.

So make it separate to hwpmc_mips module and support process/system
counting mode only.

61ebc359ca Move scterm_teken.c from 6 MD files lists to the MI files list so that it
is easier to configure.  It is MI, unlike some of the other syscons files
already in the MI list.

Move scvtb.c similarly.  It is needed whenever sc is configured, and is
more MI than most of the files already in the MI list.

This only changes the combined list for arm64 and mips.  These arches
already cannot build sc or even NOTES.

a8e3f99ec1 amd64: implement memcmp in assembly
Both the in-kernel C variant and libc asm variant have very poor performance.
The former compiles to a single byte comparison loop, which breaks down even
for small sizes. The latter uses rep cmpsq/b which turn out to have very poor
throughput and are slower than a hand-coded 32-byte comparison loop.

Depending on size this is about 3-4 times faster than the current routines.

96744f0225 Make ZSTD a real option via ZSTDIO.
It looks like the intent was to allow ZSTD support to be
compiled into the kernel with options ZSTDIO. But it doesn't look
like that was ever implemented or I'm missing how to do it.

I did a cursory audit of kernel config files and made a decision to
enable ZSTDIO in riscv GENERIC and mips MALTA configurations.  All other
kernel configurations already had this option in their kernel configs
but they didn't do anything useful as the feature was declared as
"standard" prior to this.

8038068a2a Finally, fix Zstd kernel build on MIPS and RISC-V
Add an implementation of the intrinsics invoked by __builtin_ctz{,ll} and
__builtin_clz{,ll}, and include this compilation unit on platforms that lack
assembly intrinsics for those builtins (MIPS and RISC-V).

Future cleanup work might involve bringing these into a mini libcompiler-rt
for the standalone kernel environment.  Or cleaning up the approach upstream
takes for builtins in standalone environments (or just FreeBSD).  For now,
at least this builds, and doesn't require modifying the vendor code.

fcf596178b Merge projects/ipsec into head/.
Small summary
 -------------

o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
  option IPSEC_SUPPORT added. It enables support for loading
  and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
  default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
  support was removed. Added TCP/UDP checksum handling for
  inbound packets that were decapsulated by transport mode SAs.
  setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
  build as part of ipsec.ko module (or with IPSEC kernel).
  It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
  methods. The only one header file <netipsec/ipsec_support.h>
  should be included to declare all the needed things to work
  with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
  Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
  - now all security associations stored in the single SPI namespace,
    and all SAs MUST have unique SPI.
  - several hash tables added to speed up lookups in SADB.
  - SADB now uses rmlock to protect access, and concurrent threads
    can do SA lookups in the same time.
  - many PF_KEY message handlers were reworked to reflect changes
    in SADB.
  - SADB_UPDATE message was extended to support new PF_KEY headers:
    SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
    can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
  avoid locking protection for ipsecrequest. Now we support
  only limited number (4) of bundled SAs, but they are supported
  for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
  used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
  check for full history of applied IPsec transforms.
o References counting rules for security policies and security
  associations were changed. The proper SA locking added into xform
  code.
o xform code was also changed. Now it is possible to unregister xforms.
  tdb_xxx structures were changed and renamed to reflect changes in
  SADB/SPDB, and changed rules for locking and refcounting.

"ofwpci.c", common for other platforms. The files ofw_pci.c and ofw_pci.h
from sys/powerpc/ofw no longer exist. All required declarations are moved
to sys/dev/ofw/ofwpci.h. This creates a new ofw_pci_write_ivar() function
and modifies some others methods. Most functions contain existing ppc
implementations in the majority unchanged. Now there is no need to have
multiple identical copies of methods for various architectures.

f9a5123470 Switch mips busdma to using the common busdma_buffalloc code. This amounts
to copying in some code from the armv4 busdma, and adapting a few variable
and flag names to match the surrounding mips code.

Instead of keeping a local cache of prealloced busdma_map structs on a
mutex-protected list, set up an uma zone to cache them.

Instead of all memory allocations using M_DEVBUF, use new categories
M_BUSDMA for allocations of metadata (tags, maps, segment tracking lists),
and M_BOUNCE for bounce pages.

When buffers are allocated out of the busdma_bufalloc zones the alignment
and size of the buffers is known, and the code can skip doing any "partial
cacheline flush" logic to preserve data that may be adjacent to the DMA
buffer but contain non-DMA data.

differencies. These differencies were all consolidated in the MI allocator,

As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have

2e5d5dc936 Add proper __sync_*() intrinsics for MIPS.
To make <stdatomic.h> work on MIPS (and ARM) using GCC, we need to
provide implementations of the __sync_*() functions. I already added
these functions for 4 and 8 byte types to libcompiler-rt some time ago,
based on top of <machine/atomic.h>.

Unfortunately, <machine/atomic.h> only provides a subset of the features
needed to implement <stdatomic.h>. This means that in some cases we had
to do compare-and-exchange calls in loops, where a simple ll/sc would
suffice.

Also implement these functions for 1 and 2 byte types. MIPS only
provides ll/sc instructions for 4 and 8 byte types, but this is of
course no limitation. We can simply load 4 bytes and use some bitmask
tricks to modify only the bytes affected.

2.  New modinfo for loader provided FDT blob.
3.  Common x86_init_fdt() called from hammer_time() on amd64 and
    init386() on i386.
4.  Split-off FDT specific low-level console functions from FDT
    bus methods for the uart(4) driver. The low-level console
    logic has been moved to uart_cpu_fdt.c and is used for arm,
    mips & powerpc only. The FDT bus methods are shared across
    all architectures.
5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
    fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.
