34a3091cc3 Turn off acpi_timer_test on !i386 by default
The ACPI timer test was introduced in 2002 to detect an erratum in
chipsets used with Pentium II and Pentium III processors.  No other
hardware is known to be affected, so on non-i386 systems it should
be safe to skip the test.

Turning off this test speeds up the FreeBSD boot process by roughly
140 ms on an EC2 c5.xlarge instance.

The previous behaviour can be restored by setting
hw.acpi.timer_test_enabled=1
in /boot/loader.conf.

8edd7155aa Hide acpi_timer_test behind a tunable
When hw.acpi.timer_test_enabled is set to 0, this makes acpi_timer_test
return 1 without actually testing the ACPI timer; this results in the
ACPI-fast timecounter always being used rather than potentially using
ACPI-safe.

The ACPI timer testing was introduced in 2002 as a workaround for
errata in Pentium II and Pentium III chipsets, and is unlikely to be
needed in 2021.

While I'm here, add TSENTER/TSEXIT to make it easier to see the time
spent on the test (if it is enabled).

61bb00e528 ixgbe: cleanup spelling mistakes in comments
Several functions in the driver code have a weird function comment
formatting which uses two spaces instead of only one space for the main
function body.

This formatting will be mechanically fixed by sed in a future patch, but
doing so leads to some spelling warnings on that patch. Cleanup the
spelling mistakes that will be detected first. This way, it is easier to
verify the mechanical transformation done by sed in the following patch.

beginning to set up the external PHY link speed to ensure that the
controller can acquire the link.

d357a27643 ixgbe: fix infinite recursion on PCIe link down
In some corner cases the functions ixgbe_clear_rar_generic and
ixgbe_clear_vmdq_generic may call one another leading to infinite
recursion.

When ixgbe_clear_vmdq_generic is called with IXGBE_CLEAR_VMDQ_ALL
flag, it's going to clear MPSAR registers, and proceed to call
ixgbe_clear_rar_generic, which in turn will clear the RAR registers,
and recursively call back ixgbe_clear_vmdq_generic. Normally, the
latter would detect that MPSAR registers have already been cleared
and terminate the recursion.

However, when PCIe link is down, and before the driver has had the
opportunity to shut itself down, all register reads return 0xFFFFFFFF,
and all register writes fail silently. In such case, because
ixgbe_clear_vmdq_generic blindly assumes that clearing MPSAR registers
succeeded, it's going to always call ixgbe_clear_rar_generic, which
in turn will always call back ixgbe_clear_vmdq_generic, creating
infinite recursion.

This patch re-reads MPSAR register values after they had been cleared.
In case of PCIe link failure, the values read will be non-zero, which
will terminate the recursion. On the other hand, under normal
circumstances the value read from MPSAR registers is going to be equal
to the value previously written, so this patch is expected not to cause
any regressions.

1d8cda26ca vmd(4): Major driver refactoring
- Re-implement pcib interface to use standard pci bus driver on top of
vmd(4) instead of custom one.
 - Re-implement memory/bus resource allocation to properly handle even
complicated configurations.
 - Re-implement interrupt handling to evenly distribute children's MSI/
MSI-X interrupts between available vmd(4) MSI-X vectors and setup them
to be handled by standard OS mechanisms with minimal overhead, except
sharing when unavoidable.

Successfully tested on Dell XPS 13 laptop with Core i7-1185G7 CPU (VMD
device ID 0x9a0b) and single NVMe SSD, dual-booting with Windows 10.

Successfully tested on Supermicro X11DPI-NT motherboard with Xeon(R)
Gold 6242R CPUs (VMD device ID 0x201d), simultaneously handling NVMe
SSD on one PCIe port and PLX bridge with 3 NVMe and 1 AHCI SSDs on
another.  Handles SSD hot-plug (except Optane 905p for some reason,
which are not detected until manual bus rescan) and enabled IOMMU
(directly connected SSDs work, but ones connected to the PLX fail
without errors from IOMMU).

75547acf1c vmd: Rename vmd_bus class to pci
This fixes a kernel panic when probing for vmd_bus on Intel TigerLake on
14-CURRENT. Apparently, vmd_bus is a type of PCI bus, but was registered
as a separate device class.

rtsx copied code from sdhci, and has the same wakeup race bug that was
fixed in 35547df5c7, so apply a similar fix here.

4174302b4a evdev: Add implicit mode for touch tracking.
In implicit mode assignment of slot number and tracking id is performed
automatically on each synchronization requested by device driver.

This is done with creation of intermediate buffer for multitouch events.
This buffer holds untracked events until synchronization is requested by
device driver. It is needed as touch assigment requires
knowledges of all touch positions pushed in current and previous reports.

b79de251fc evdev: Import support for touch-tracking.
Touch tracking is a process of assignment of unique trackingID to each
initiated contact on the surface.  Keeping the trackingIDs persistent
across multitouch reports requires solving of so called Euclidian
Bipartite Matching problem.

This commit imports EBM-solver implementation based on Dinitz-Kronrod
algorithm to find minimum cost matching between contacts listed in two
consecutive reports.

a437dfa5ca evdev: Multitouch code style changes.
1. Move touch count reporting helpers to utils. They are not multitouch.
2. Use evdev_mt prefix for private multitouch support routines.
3. Use int instead of int32_t where fixed size is not required.
4. Export some internal functions.

This change should be no-op.

e8df60a69a routing: Allow using IPv6 next-hops for IPv4 routes (RFC 5549).
Implement kernel support for RFC 5549/8950.

* Relax control plane restrictions and allow specifying IPv6 gateways
 for IPv4 routes. This behavior is controlled by the
 net.route.rib_route_ipv6_nexthop sysctl (on by default).

* Always pass final destination in ro->ro_dst in ip_forward().

* Use ro->ro_dst to exract packet family inside if_output() routines.
 Consistently use RO_GET_FAMILY() macro to handle ro=NULL case.

* Pass extracted family to nd6_resolve() to get the LLE with proper encap.
 It leverages recent lltable changes committed in c541bd368f.

Presence of the functionality can be checked using ipv4_rfc5549_support feature(3).
Example usage:
  route add -net 192.0.0.0/24 -inet6 fe80::5054:ff:fe14:e319%vtnet0

b036a48de6 md: Clamp to a multiple of the sector size when resizing
We do this when creating md(4) devices, in kern_mdattach_locked(), but
not when resizing the provider.  Apply the same policy when resizing, as
many GEOM classes do not expect to deal with providers for which
pp->mediasize % pp->sectorsize != 0.
