aafdd1d65a The broken DDR52 support of Intel Bay Trail eMMC controllers rumored
in the commit log of r321385 has been confirmed via the public VLI54
erratum. Thus, stop advertising DDR52 for these controllers.
Note that this change should hardly make a difference in practice as
eMMC chips from the same era as these SoCs most likely support HS200
at least, probably even up to HS400ES.

It appears that domain information is set correctly independent
of whether or not NUMA is defined. However, there is no memory

e6b475e0af hwpmc(9): Make pmclog buffer pcpu and update constants
On non-trivial SMP systems the contention on the pmc_owner mutex leads
to a substantial number of samples captured being from the pmc process
itself. This change a) makes buffers larger to avoid contention on the
global list b) makes the working sample buffer per cpu.

Run pmcstat in the background (default event rate of 64k):
pmcstat -S UNHALTED_CORE_CYCLES -O /dev/null sleep 600 &

Before:
make -j96 buildkernel -s >&/dev/null 3336.68s user 24684.10s system 7442% cpu 6:16.50 total

After:
make -j96 buildkernel -s >&/dev/null 2697.82s user 1347.35s system 6058% cpu 1:06.77 total

For more realistic overhead measurement set the sample rate for ~2khz
on a 2.1Ghz processor:
pmcstat -n 1050000 -S UNHALTED_CORE_CYCLES -O /dev/null sleep 6000 &

3096900d09 vxge(4): deprecation notice
This hardware isn't totally ancient, about equal to a mxge(4) or mlx4en(4),
but the company was sold to Exar which then promptly exited the Ethernet
business so the card was commercially available for under 2 years. On deep
search, the only usage of these cards I found was by the importing of the
driver. There are code quality issues identified by Brooks and Hiren and
no visible use nor maintainership that warrant removal from FreeBSD 12.0.

5e251aec86 vt(4): Use default VGA palette
Before this change, the VGA palette was configured to match the shell
palette (e.g. color #1 was red). There was one glitch early in boot when
the vt(4)'s VGA palette was loaded: the loader's logo would switch from
red to blue. Likewise for the "Booting..." message switching from blue
to red. That's because the loader's logo was drawed with the default VGA
palette where a few colors are swapped compared to the shell palette
(e.g. blue <-> red).

This change configures the default VGA palette during initialization and
converts input's colors from shell to VGA palette index.

There should be no visible changes, except the loader's logo which will
keep its original color.

is `COLOR_FORMAT_RGB`).

2339f28c6e Do not pass header length to the ENA controller
Header length is optional hint for the ENA device. Because It is not
guaranteed that every packet header will be in the first mbuf
segment, it is better to skip passing any information. If the header
length will be indicating invalid value (different than 0), then the
packet will be dropped.

This kind situation can appear, when the UDP packet will be fragmented
by the stack in the ip_fragment() function.

dbf2eb543b Skip setting the MTU for ENA if it is not changing
On AWS, a network interface can get reinitialized every 30 minutes due
to the MTU being (re)set when a new DHCP lease is obtained. This can
cause packet drop, along with annoying syslog messages.

Skip setting the MTU in the ena driver if the new MTU is the same as the
old MTU. Note this fix is already in the netfront driver.

Testing: Verified ena up/down messages do not appear every 30 min in
/var/log/messages with the fix in place.

89f651e704 cxgbe(4): Add support for hash filters.
These filters reside in the card's memory instead of its TCAM and can be
configured via a new "hashfilter" subcommand in cxgbetool.  Hash and
normal TCAM filters can be used together.  The hardware does an
exact-match of packet fields for hash filters, unlike the masked match
performed for TCAM filters.  Any T5/T6 card with memory can support at
least half a million hash filters.  The sample config file with the
driver configures 512K of these, it is possible to double this to 1
million+ in some cases.

The chip does an exact-match of fields of incoming datagrams with hash
filters and performs the action configured for the filter if it matches.
The fields to match are specified in a "filter mask" in the firmware
config file.  The filter mask always includes the 5-tuple (sip, dip,
sport, dport, ipproto).  It can, optionally, also include any subset of
the filter mode (see filterMode and filterMask in the firmware config
file).

For example:
filterMode = fragmentation, mpshittype, protocol, vlan, port, fcoe
filterMask = protocol, port, vlan

Exact values of the 5-tuple, the physical port, and VLAN tag would have
to be provided while setting up a hash filter with the chip
configuration above.

Hash filters support all actions supported by TCAM filters.  A packet
that hits a hash filter can be dropped, let through (with optional
steering to a specific queue or RSS region), switched out of another
port (with optional L2 rewrite of DMAC, SMAC, VLAN tag), or get NAT'ed.
(Support for some of these will show up in the driver in a follow-up
commit very shortly).

34577ddb15 amdsbwd: fix reboot status reporting
Originally, I overlooked that PMIO register 0xc0 has a dual personality.
It can either be S5/Reset Status register or Misc. Fix register (aka
debug status register).  The mode is controlled by bit 2 in PMIO
register 0xc4.  Apparently there are register programming requirements
for the second personality, so many BIOSes leave the register, after
programming it, in that mode.  So, we need to switch the register to the
correct mode.

Additionally, AMDSB8_WD_RST_STS was defined incorrectly as bit 13 while
it is actually bit 25 (and the register's width is 32 bits, not 16).

With this change I see the following in dmesg after a reset by the
watchdog:
amdsbwd0: ResetStatus = 0x42000000
amdsbwd0: Previous Reset was caused by Watchdog

2602ef7cfa xen: fix gntdev
Current interface to the gntdev in FreeBSD is wrong, and mostly worked
out of luck before the PTI FreeBSD fixes, when kernel and user-space
where sharing the same page tables.

On FreeBSD ioctls have the size of the passed struct encoded in the
ioctl number, because the generic ioctl handler in the OS takes care
of copying the data from user-space to kernel space, and then calls
the device specific ioctl handler. Thus using ioctl structs with
variable sizes is not possible.

The fix is to turn the array of structs at the end of
ioctl_gntdev_alloc_gref and ioctl_gntdev_map_grant_ref into pointers,
that can be properly accessed from the kernel gntdev driver using the
copyin/copyout functions. Note that this is exactly how it's done for
the privcmd driver.

to adding the device name to kern.console sysctl, although doing that
requires jumping through some hoops.  It doesn't change the actual
operation of those virtual devices.  The point is to make it possible
for init(8) to recognize them as console devices and to launch getty(8)
for them, when configured as "onifconsole" in ttys(5).  The point of
that, in turn, is to add such entries to the default ttys(5), so that
init(8) will launch gettys for device-side "virtual serial adapters",
but not for actual USB serial dongles.

bfeb2bd7ca regulator: Check status before disabling
When disabling regulator when they are unused, check before is they are
enabled.
While here don't check the enable_cnt on the regulator entry as it is
checked by regnode_stop.
This solve the panic on any board using a fixed regulator that is driven
by a gpio when the regulator is unused.

8aa1c1d8b4 cxgbe(4): Fix bugs in the handling of COP rules that match on VLAN tag.
Retrieve the tag from the correct ifnet and use the provided tag
(instead of hardcoded 0xffff, implying no tag) in the routines that
process offload policy.

b3e85e7a79 Intel drives have an optimal alignment for I/O. While they honor I/Os
that cross this boundary, they perform better when this isn't the
case. Intel uses the 3rd byte in the vendor specific area for
this. The DC P3500 was previously listed without any explanation. Add
the DC P3520 and DC P4500 to the list.

There won't be any others drives needing this quirk. Intel has
standardized a field in the namespace data in 1.3 (noiob).  A future
patch will use that if it exists, with fallback to this method.

eb33d8ce3e Workaround fixed I/O port resources encoded as I/O port ranges in _CRS.
ACPI I/O port descriptors use _MIN and _MAX fields to specify the set
of allowable base (start) addresses for an I/O port resource along with
a _LEN field specifying the length.  A fixed resource is supposed to be
encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to
the end of the fixed range.  Relocating I/O ranges only make sense in
_PRS (possible resource settings), not in _CRS (current resource settings),
so if an I/O port range with _MAX set set to the end of the range is
present in _CRS, treat it as a fixed I/O port resource starting at
_MIN.

bca3808097 Restore SIOCGI2C functionality to ixgbe
When ixgbe was converted to iflib, it lost the SIOCGI2C support
that allows ifconfig to print SFP state, optical light levels, etc.
Restore this by plugging in to the ifdi_i2c_req iflib method.  Note
that the sanity checking on dev_addr that used to be done in ixgbe is
now done in iflib.

1131c927c4 cxgbe(4): Add support for Connection Offload Policy (aka COP).
COP allows fine-grained control on whether to offload a TCP connection
using t4_tom, and what settings to apply to a connection selected for
offload.  t4_tom must still be loaded and IFCAP_TOE must still be
enabled for full TCP offload to take place on an interface.  The
difference is that IFCAP_TOE used to be the only knob and would enable
TOE for all new connections on the inteface, but now the driver will
also consult the COP, if any, before offloading to the hardware TOE.

A policy is a plain text file with any number of rules, one per line.
Each rule has a "match" part consisting of a socket-type (L = listen,
A = active open, P = passive open, D = don't care) and a pcap-filter(7)
expression, and a "settings" part that specifies whether to offload the
connection or not and the parameters to use if so.  The general format
of a rule is: [socket-type] expr => settings

Example.  See cxgbetool(8) for more information.
[L] ip && port http => offload
[L] port 443 => !offload
[L] port ssh => offload
[P] src net 192.168/16 && dst port ssh => offload !nagle !timestamp cong newreno
[P] dst port ssh => offload !nagle ecn cong tahoe
[P] dst port http => offload
[A] dst port 443 => offload tls
[A] dst net 192.168/16 => offload !timestamp cong highspeed

The driver processes the rules for each new listen, active open, or
passive open and stops at the first match.  There is an implicit rule at
the end of every policy that prohibits offload when no rule in the
policy matches:
[D] all => !offload

This is a reworked and expanded version of a patch submitted by
Krishnamraju Eraparaju @ Chelsio.

3a4fc8a8a1 Remove support for the Arcnet protocol.
While Arcnet has some continued deployment in industrial controls, the
lack of drivers for any of the PCI, USB, or PCIe NICs on the market
suggests such users aren't running FreeBSD.

Evidence in the PR database suggests that the cm(4) driver (our sole
Arcnet NIC) was broken in 5.0 and has not worked since.

d86c1f0dc1 i386 4/4G split.
The change makes the user and kernel address spaces on i386
independent, giving each almost the full 4G of usable virtual addresses
except for one PDE at top used for trampoline and per-CPU trampoline
stacks, and system structures that must be always mapped, namely IDT,
GDT, common TSS and LDT, and process-private TSS and LDT if allocated.

By using 1:1 mapping for the kernel text and data, it appeared
possible to eliminate assembler part of the locore.S which bootstraps
initial page table and KPTmap.  The code is rewritten in C and moved
into the pmap_cold(). The comment in vmparam.h explains the KVA
layout.

There is no PCID mechanism available in protected mode, so each
kernel/user switch forth and back completely flushes the TLB, except
for the trampoline PTD region. The TLB invalidations for userspace
becomes trivial, because IPI handlers switch page tables. On the other
hand, context switches no longer need to reload %cr3.

copyout(9) was rewritten to use vm_fault_quick_hold().  An issue for
new copyout(9) is compatibility with wiring user buffers around sysctl
handlers. This explains two kind of locks for copyout ptes and
accounting of the vslock() calls.  The vm_fault_quick_hold() AKA slow
path, is only tried after the 'fast path' failed, which temporary
changes mapping to the userspace and copies the data to/from small
per-cpu buffer in the trampoline.  If a page fault occurs during the
copy, it is short-circuit by exception.s to not even reach C code.

The change was motivated by the need to implement the Meltdown
mitigation, but instead of KPTI the full split is done.  The i386
architecture already shows the sizing problems, in particular, it is
impossible to link clang and lld with debugging.  I expect that the
issues due to the virtual address space limits would only exaggerate
and the split gives more liveness to the platform.
