Add new mlx5ib(4) driver to the kernel source tree which supports
Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of
PCI express network cards.
There is currently no user-space support and this driver only supports
kernel side non-routable RoCE V1. The krping kernel module can be used
to test this driver. Full user-space support including RoCE V2 will be
added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise
this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel
module will only be built when WITH_OFED=YES is specified.

Unbreak BCM2835/RPI-B support by bringing it in line with stable/11 and
head:
- Optimise reading of pending interrupt registers.
- Fix a bug where some DTS layouts could cause the premature ending of the
search (i.e. without returning any result) and you would end up with a
random MAC address.
- Reduce the diff between head and arm_intrng with the bcm2835 interrupt
controller.
- Allow the retrieving of the reserved pins state.
- Add support to the bcm2835 mailbox driver to work before interrupts are
enabled. This will be needed to enable the power on devices early on in the
boot process.
- Add support for enabling the USB on the Raspberry Pi boards when it hasn't
been done by U-Boot. This allows the USB to work when we load the kernel
directly.
- Call config_intrhook_disestablish on failure of the bcm2835 fb and fbd intr
hooks. With this we can get through the boot even if these functions fail.
- Add the structures needed to get/set the power state. These can be used
when, for example, we boot without U-Boot and wish to enable USB, or to
suspend an unneeded device.
- Add a mask to match only the relative base address of BSC controllers.
- Move the code to set the device power to the bcm2835 mailbox driver so it
can be reused by other drivers.
- Add the SOC_BCM2835 and SOC_BCM2836 options for the arm kernel and add the
former to std.bcm2835.
- Add a helper function to read clock frequencies from videocore and use this
to get the default frequency of the sdhci device.
- Add partial support for the Raspberry Pi 2.
- Remove a debug #error from the bcm2835 sdhci driver.
- Fetch the SDHCI frequency from videocore (our prefered source) and only if
it fails, fetch the clock-frequency from DTB. If both methods fail, use the
hardcoded default.
- Pass the supplied buffer length instead of a fixed size.
- Add the routines to query and setup the framebuffer state using the
BCM2835_MBOX_CHAN_PROP channel. The old channel (BCM2835_MBOX_CHAN_FB)
seems deprecated on recent firmware versions and is causing a freeze on
RPi 2.
- Fix DMA on RPi 2. BCM2836 has a different base address for peripherals.
- Enable DMA for sdhci on RPi 2 (BCM2836).
- Add a missing wakeup when releasing ownership of the SPI hardware.
- Fix framebuffer compatibility with new RPi firmware.
- Refactor bcm2835_cpufreq to use bcm2835_mbox_property API.
- Fix the sc(4) framebuffer driver on RPi 2.
- Fix the vt(4) framebuffer driver on RPi 2.
- Remove unused mutex and softc variables.
- Refactor mailbox property API to make it usable for /dev/vcio driver.
- Replace semaphore-base locking with sleep/wait synchronization.
- Fix infinite loop if response from VideoCore never received.
- Set have_message in interrupt to handle "response before READ" case.
- Serialize access to property channel when using bcm2835_mbox_property.
- Force framebuffer virtual viewport to be the same as physical.
- Use proper type of tag in bcm2835_mbox_fb_init.
- bcm2835_cpufreq: Only attach driver if we correcly match on the machine
compatible string.
- Add dev.fb.X.resync sysctl to resync ARM framebuffer with VideoCore.
- Do not use DMA channels used by GPU.
- Define local-intc for BCM2836 platform (RPI2) and make BCM2835 intc
a child of it.
- Fix build for Pi kernels with syscons enabled.
- Use VM_MEMATTR_WRITE_COMBINING memattr for mmap(2) on framebuffer.
- Make intc driver compatible with upstream DTS.
- Make Rapsberry Pi watchdog driver compatible with upstream DTS.
- Make sure intc is attached before interrupt consumers.
- Make framebuffer driver compatible with upstream DT.
- Add one more heuristic to determine MAC address of the SMSC device.
- Add compatibility strings from upstream DT.
- Fix spelling mistake, BCM2835_PASWORD -> BCM2835_PASSWORD.

Add support for reading advanced diagnostic counters.
By default reading the diagnostic counters is disabled. The firmware
decides which counters are supported and only those supported show up
in the dev.mce.X.diagnostics sysctl tree.
To enable reading of diagnostic counters set one or more of the
following sysctls to one:
dev.mce.X.conf.diag_general_enable=1
dev.mce.X.conf.diag_pci_enable=1

Move the SCTP syscalls to netinet with the rest of the SCTP code. The
syscalls themselves are tightly coupled with the network stack and
therefore should not be in the generic socket code.
The following four syscalls have been marked as NOSTD so they can be
dynamically registered in sctp_syscalls_init() function:
sys_sctp_peeloff
sys_sctp_generic_sendmsg
sys_sctp_generic_sendmsg_iov
sys_sctp_generic_recvmsg
The syscalls are also set up to be dynamically registered when COMPAT32
option is configured.
As a side effect of moving the SCTP syscalls, getsock_cap needs to be
made available outside of the uipc_syscalls.c source file. A proper
prototype has been added to the sys/socketvar.h header file.
API tests from the SCTP reference implementation have been run to ensure
compatibility. (http://code.google.com/p/sctp-refimpl/source/checkout)

r317702:
cxgbe(4): Support routines for Tx traffic scheduling.
- Create a new file, t4_sched.c, and move all of the code related to
traffic management from t4_main.c and t4_sge.c to this file.
- Track both Channel Rate Limiter (ch_rl) and Class Rate Limiter (cl_rl)

- Initialize all the cl_rl limiters with somewhat arbitrary default
rates and provide routines to update them on the fly.
- Provide routines to reserve and release traffic classes.

hyperv/vmbus: Reorganize vmbus device tree
For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the
resources for PCI passthrough and SR-IOV. There is no
acpi_syscontainer0 on GEN1 Hyper-V.
For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which
contains the resources for PCI passthrough and SR-IOV. There is
no pcib0 on GEN2 Hyper-V.
The ACPI VMBUS device now only holds its _CRS, which is empty as
of this commit; its existence is mainly for upward compatibility.
Device tree structure is suggested by jhb@.

r313250, r313712, r314811 (partial), r314887 (partial), r315430,
r317981, r315466
o Move the DRIVER_MODULE() statements that declare mmc(4) to be a child
of the various bridge drivers out of dev/mmc.c and into the bridge
drivers.
o Add ACPI platform support for SDHCI driver.
o Fix some overly long lines, whitespace and other bugs according to
style(9) as well as spelling etc. in mmc(4), mmcsd(4) and sdhci(4).
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
- Remove redundant assignments of the default bus_generic_print_child
device method,
- use DEVMETHOD_END,
- use NULL instead of 0 for pointers.
o Trim/adjust includes.
o Add and use a MMC_DECLARE_BRIDGE macro for declaring mmc(4) bridges
as kernel drivers and their dependency onto mmc(4).
o Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
provide up to:
1 enhanced user data area partition
2 boot partitions
1 RPMB (Replay Protected Memory Block) partition
4 general purpose partitions (optionally with a enhanced or extended
attribute)
Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
code in the boot partitions etc., another use case for the partition
support is the activation of pseudo-SLC mode, which manufacturers of
eMMC chips typically associate with the enhanced user data area and/
or the enhanced attribute of general purpose partitions.
CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.
o Now that properly issuing CMD6 is crucial (so data isn't written to
the wrong partition for example), make a step into the direction of
correctly handling the timeout for these commands in the MMC layer.
Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
recommended by relevant specifications.
o Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
with Linux so that the GNU mmc-utils can be ported to and used with
FreeBSD (note that due to the remaining deficiencies outlined above
SANITIZE operations issued by/with `mmc` currently most likely will
fail). These latter have been added to ports as sysutils/mmc-utils.
Among others, the `mmc` tool of mmc-utils allows for partitioning
eMMC devices (tested working).
o For devices following the eMMC specification v4.41 or later, year 0
is 2013 rather than 1997; so correct this for assembling the device
ID string properly.
o Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
least for some of the above a matching pair is required.

Stop building vers.c in include/ and only build the needed osreldate.h.
Because of how osreldate.h was being built with newvers.sh, which always
spat out a vers.c dependent on SVN or git, the meta mode build was
considering osreldate.h to depend on the current git or SVN index. This
would lead to entire tree rebuilds when modifying git's index. There's
no reason to be generating vers.c here so just skip it.
While here, in mk-osreldate.sh rename PARAM_H to proper PARAMFILE (which
newvers.sh already has a default for) and remove unneeded export.

Use "build" instead of "all" when building ports modules
"all" in ports currently means "stage the ports", which requires root today,
and brings to light other potential issues, like ENAMETOOLONG with staged
directories (bug 161481, etc).
This fixes buildkernel for me when run as a non-root user, assuming all
of the prerequisites have been installed beforehand and are up-to-date.

hyperv/vss: Add driver and tools for VSS
VSS stands for "Volume Shadow Copy Service". Unlike virtual machine
snapshot, it only takes snapshot for the virtual disks, so both
filesystem and applications have to aware of it, and cooperate the
whole VSS process.
This driver exposes two device files to the userland:
/dev/hv_fsvss_dev
Normally userland programs should _not_ mess with this device file.
It is currently used by the hv_vss_daemon(8), which freezes and
thaws the filesystem. NOTE: currently only UFS is supported, if
the system mounts _any_ other filesystems, the hv_vss_daemon(8)
will veto the VSS process.
If hv_vss_daemon(8) was disabled, then this device file must be
opened, and proper ioctls must be issued to keep the VSS working.
/dev/hv_appvss_dev
Userland application can opened this device file to receive the
VSS freeze notification, hold the VSS for a while (mainly to flush
application data to filesystem), release the VSS process, and
receive the VSS thaw notification i.e. applications can run again.
The VSS will still work, even if this device file is not opened.
However, only filesystem consistency is promised, if this device
file is not opened or is not operated properly.
hv_vss_daemon(8) is started by devd(8) by default. It can be disabled
by editting /etc/devd/hyperv.conf.

Turn on FC-Tape by default in the isp(4) driver.
FC-Tape provides additional link level error recovery, and is
highly recommended for tape devices. It will only be turned on for
a given target if the target supports it.
Without this setting, we default to whatever FC-Tape setting is in
NVRAM on the card.
This can be overridden by setting the following loader tunable, for
example for isp0:
hint.isp.0.nofctape=1
sys/conf/options:
Add a new kernel config option, ISP_FCTAPE_OFF, that
defaults the FC-Tape configuration to off.
sys/dev/isp/isp_pci.c:
If ISP_FCTAPE_OFF is defined, turn off FC-Tape. Otherwise,
turn it on if the card supports it.
share/man/man4/isp.4:
Add a description of FC-Tape to the isp(4) man page.
Add descriptions of the fctape and nofctape options, as well as the
ISP_FCTAPE_OFF kernel configuration option.
Add the ispfw module and kernel drivers to the suggested
configurations at the top of the man page so that users are less
likely to leave it out. The driver works well with the included
firmware, but may not work at all with whatever firmware the user
has flashed on their card.

306465,309302:
Add support for adapters using the Terminator T6 ASIC.
305695:
cxgbe(4): Set up fl_starve_threshold2 accurately for T6.
305696:
cxgbe(4): Use correct macro for header length with T6 ASICs. This
affects the transmit of the VF driver only.
305699:
cxgbe(4): Update the pad_boundary calculation for T6, which has a
different range of boundaries.
305702:
cxgbe(4): Use smaller min/max bursts for fl descriptors with a T6.
305703:
cxgbe(4): Deal with the slightly different SGE_STAT_CFG in T6.
305713:
cxgbe(4): Add support for additional port types and link speeds.
305715:
cxgbe(4): Catch up with the rename of tlscaps -> cryptocaps. TLS is one
of the capabilities of the crypto engine in T6.
305827:
cxgbe(4): Use the interface's viid to calculate the PF/VF/VFValid fields
to use in tx work requests.
305852:
cxgbe(4): Attach to cards with the Terminator 6 ASIC. T6 cards will
come up as 't6nex' nexus devices with 'cc' ports hanging off them.
The T6 firmware and configuration files will be added as soon as they
are released. For now the driver will try to work with whatever
firmware and configuration is on the card's flash.
305906:
cxgbe/t4_tom: The SMAC entry for a VI is at a different location in the T6.
305908:
cxgbe/t4_tom: Update the active/passive open code to support T6. Data
path works as-is.
306062:
cxgbe(4): Show wcwr_stats for T6 cards.
306063:
cxgbe(4): Setup congestion response for T6 rx queues.
306137:
cxgbetool: Add T6 support to the SGE context decoder.
306138:
Fix typo.
306206:
cxgbe(4): Catch up with the different layout of WHOAMI in T6.
Note that the code moved below t4_prep_adapter() as part of this change
because now it needs a working chip_id().
306216:
cxgbe(4): Fix the output of the "tids" sysctl on T6.
306273:
cxgbe(4): Fix netmap with T6, which doesn't encapsulate SGE_EGR_UPDATE
message inside a FW_MSG. The base NIC already deals with updates in
either form.
306295:
cxgbe(4): Support SIOGIFXMEDIA so that ifconfig displays correct media
for 25Gbps and 100Gbps ports. This should have been part of r305713,
which is when the driver first started reporting extended media types.
306301:
cxgbe(4): Use the port's top speed to figure out whether it is "high
speed" or not (for the purpose of calculating the number of queues etc.)
This does the right thing for 25Gbps and 100Gbps ports.
306465:
cxgbe(4): Claim the T6 -DBG card.
309302:
cxgbe(4): Include firmware for T6 cards in the driver. Update all
firmwares to 1.16.12.0.

Chelsio T4/T5 VF driver.
303522:
Various fixes to the t4/5nex character device.
- Remove null open/close methods.
- Don't set d_flags to 0 explicitly.
- Remove t5_cdevsw as the .d_name member isn't really used and doesn't
warrant a separate cdevsw just for the name.
- Use ENOTTY as the error value for an unknown ioctl request.
- Use make_dev_s() to close race with setting si_drv1.
303647:
Store the offset of the KDOORBELL and GTS registers in the softc.
VF devices use a different register layout than PF devices. Storing
the offset in a value in the softc allows code to be shared between the
PF and VF drivers.
303860:
Reserve an adapter flag IS_VF to mark VF devices vs PF devices.
303880:
Track the base absolute ID of ingress and egress queues.
Use this to map an absolute queue ID to a logical queue ID in interrupt
handlers. For the regular cxgbe/cxl drivers this should be a no-op as
the base absolute ID should be zero. VF devices have a non-zero base
absolute ID and require this change. While here, export the absolute ID
of egress queues via a sysctl.
304168:
Make SGE parameter handling more VF-friendly.
Add fields to hold the SGE control register and free list buffer sizes to
the sge_params structure. Populate these new fields in
t4_init_sge_params() for PF devices and change t4_read_chip_settings() to
pull these values out of the params structure instead of reading
registers directly. This will permit t4_read_chip_settings() to be reused
for VF devices which cannot read SGE registers directly.
While here, move the call to t4_init_sge_params() to
get_params__post_init(). The VF driver will populate the SGE parameters
structure via a different method before calling t4_read_chip_settings().
304169:
Update mailbox writes to work with VF devices.
- Use alternate register locations for the data and control registers for
VFs.
- Do a dummy read to force the writes to the mailbox data registers to
post before the write to the control register on VFs.
- Do not check the PCI-e firmware register for errors on VFs.
304170:
Add support for register dumps on VF devices.
- Add handling of VF register sets to t4_get_regs_len() and t4_get_regs().
- While here, use t4_get_regs_len() in the ioctl handler for regdump
instead of inlining it.
304479:
Add structures for VF-specific adapter parameters.
While here, mark which parameters are PF-specific and which are
VF-specific.
304482:
Adjust t4_port_init() to work with VF devices.
Specifically, the FW_PORT_CMD may or may not work for a VF (the PF
driver can choose whether or not to permit access to this command),
so don't attempt to fetch port information on a VF if permission is
denied by the PF.
304485:
Reorder sysctls so that nodes shared with the VF driver are added first.
This permits a single early return for VF devices in the routines that
add sysctl nodes.
305548:
Don't break out of the m_advance() loop if len drops to zero.
If a packet contains the Ethernet header (14 bytes) in the first mbuf
and the payload (IP + UDP + data) in the second mbuf, then the attempt
to fetch the l3hdr will return a NULL pointer. The first loop iteration
will drop len to zero and exit the loop without setting 'p'. However,
the desired data is at the start of the second mbuf, so the correct
behavior is to loop around and let the conditional set 'p' to m_data of
the next mbuf (and leave offset as 0).
305549:
Chelsio T4/T5 VF driver.
The cxgbev/cxlv driver supports Virtual Function devices for Chelsio
T4 and T4 adapters. The VF devices share most of their code with the
existing PF4 driver (cxgbe/cxl) and as such the VF device driver
currently depends on the PF4 driver.
Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf
PCI device driver that attaches to the VF device. It then creates
child cxgbev/cxlv devices representing ports assigned to the VF.
By default, the PF driver assigns a single port to each VF.
t4vf_hw.c contains VF-specific routines from the shared code used to
fetch VF-specific parameters from the firmware.
t4_vf.c contains the VF-specific PCI device driver and includes its
own attach routine.
VF devices are required to use a different firmware request when
transmitting packets (which in turn requires a different CPL message
to encapsulate messages). This alternate firmware request does not
permit chaining multiple packets in a single message, so each packet
results in a firmware request. In addition, the different CPL message
requires more detailed information when enabling hardware checksums,
so parse_pkt() on VF devices must examine L2 and L3 headers for all
packets (not just TSO packets) for VF devices. Finally, L2 checksums
on non-UDP/non-TCP packets do not work reliably (the firmware trashes
the IPv4 fragment field), so IPv4 checksums for such packets are
calculated in software.
Most of the other changes in the non-VF-specific code are to expose
various variables and functions private to the PF driver so that they
can be used by the VF driver.
Note that a limited subset of cxgbetool functions are supported on VF
devices including register dumps, scheduler classes, and clearing of
statistics. In addition, TOE is not supported on VF devices, only for
the PF interfaces.

hyperv/vmbus: add a new method to get vcpu_id
vcpu_id is host's representation of guest CPU.
We get the mapping between vcpu_id and FreeBSD kernel's cpu id when VMBus
driver is loaded. Later, when a driver, like the coming pcib driver, talks
to the host and needs to refer to a guest CPU, the driver must use the
vcpu_id.

r308725
hyperv/pcib: enable PCIe pass-through (a.k.a. Discrete Device Assignment)
The feature enables us to pass through physical PCIe devices to FreeBSD VM
running on Hyper-V (Windows Server 2016) to get near-native performance with
low CPU utilization.
The patch implements a PCI bridge driver to support the feature:
1) The pcib driver talks to the host to discover device(s) and presents
the device(s) to FreeBSD's pci driver via PCI configuration space (note:
to access the configuration space, we don't use the standard I/O port
0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V,
which is very similar to the 0xCF8/CFC method).
2) The pcib driver allocates resources for the device(s) and initialize
the related BARs, when the device driver's attach method is invoked;
3) The pcib driver talks to the host to create MSI/MSI-X interrupt
remapping between the guest and the host;
4) The pcib driver supports device hot add/remove.

296493-296496,296544,296710-296711,297863,299685: Catch up to changes to
the internal shared code.
Note that this merge includes two different firmware updates, but the
effective change is to update to the last version (1.15.37.0). As such,
I've trimmed the log message of the first update (1.15.28.0).
In addition, the M_WAIT macro added in t4_regs.h had to be renamed to
CXGBE_M_WAIT to avoid a collision on 10.x that is not present on 11.
295778:
cxgbe: catch up with the latest hardware-related definitions.
296249:
cxgbe(4): Update T5 and T4 firmwares to 1.15.28.0.
296333:
cxgbe(4): First of many changes to reduce diffs with internal shared
code:
- Rename some CamelCase variables.
- s/t4_link_start/t4_link_l1cfg/g
- Pull in t4_get_port_type_description.
- Move t4_wait_op_done to t4_hw.c.
- Flip the order of the RDMA stats.
- Remove unsused function t4_iq_start_stop.
- Move t4_wait_op_done and t4_wait_op_done_val to t4_hw.c
296383:
cxgbe(4): Very basic T6 awareness. This is part of ongoing work to
update to the latest internal shared code.
- Add a chip_params structure to keep track of hardware constants for
all generations of Terminators handled by cxgbe.
- Update t4_hw_pci_read_cfg4 to work with T6.
- Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to
work with T6. Most of the changes are in the decoders for the CIM
logic analyzer and the MPS TCAM.
- Acquire the regwin lock around indirect register accesses.
296471:
cxgbe(4): Updated register dumps.
- Get the list of registers to read during a regdump from the shared
code instead of the OS specific code. This follows a similar move
internally. The shared code includes the list for T6.
- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register
dumps (and catch up with some updates to T4 and T5 register decode).
296478:
cxgbe(4): Add a struct sge_params to store per-adapter SGE parameters.
Move the code that reads all the parameters to t4_init_sge_params in the
shared code. Use these per-adapter values instead of globals.
296481:
cxgbe(4): Overhaul the shared code that deals with the chip's TP block,
which is responsible for filtering and RSS.
Add the ability to use filters that match on PF/VF (aka "VNIC id") while
here. This is mutually exclusive with filtering on outer VLAN tag with
Q-in-Q.
296485:
cxgbe(4): Update the interrupt handlers for hardware errors.
296488:
cxgbe(4): Updates to mailbox routines in the shared code.
296489:
cxgbe(4): Updates to the shared routines that deal with the serial EEPROM,
flash, and VPD.
296490:
cxgbe(4): Remove __devinit and SPEED_<foo> as part of catch up with
internal shared code.
296491:
cxgbe(4): Updates to shared routines that get/set various parameters via
the firmware.
296493:
cxgbe(4): Use t4_link_down_rc_str in shared code to decode the reason
the link is down, instead of doing it in OS specific code.
296494:
cxgbe(4): Many new functions in the shared code, unused at this time.
296495:
cxgbe(4): Fix t4_tp_get_rdma_stats.
296496:
cxgbe(4): Minor updates to the shared routines that deal with firmware images.
296544:
cxgbe(4): Reshuffle and rototill t4_hw.c, solely to reduce diffs with
the internal shared code.
296710:
cxgbe(4): Catch up with the latest list of card capabilities as reported
by the firmware.
296711:
cxgbe(4): Fix typo in previous commit.
297863:
Rename the 'M_B' macro in t4_regs.h to 'CXGBE_M_B'.
This fixes a conflict with the M_B macro in powerpc's
<machine/db_machdep.h> exposed by the recent addition of DDB commands
to the cxgbe driver.
299685:
cxgbe(4): Update T5 and T4 firmwares to 1.15.37.0.
These firmwares were obtained from the "Chelsio T5/T4 Unified Wire
v2.12.0.3 for Linux" release. Changes since 1.14.4.0 (which is the
firmware in -STABLE branches) are in the "Release Notes" accompanying
the Unified Wire release and are copy-pasted here as well.
