MFC r330304: imcsmb(4): Intel integrated Memory Controller (iMC) SMBus controller driver
imcsmb(4) provides smbus(4) support for the SMBus controller functionality in the integrated Memory Controllers (iMCs) embedded in Intel Sandybridge- Xeon, Ivybridge-Xeon, Haswell-Xeon, and Broadwell-Xeon CPUs. Each CPU implements one or more iMCs, depending on the number of cores; each iMC implements two SMBus controllers (iMC-SMBs).
*** IMPORTANT NOTE *** Because motherboard firmware or the BMC might try to use the iMC-SMBs for monitoring DIMM temperatures and/or managing an NVDIMM, the driver might need to temporarily disable those functions, or take a hardware interlock, before using the iMC-SMBs. Details on how to do this may vary from board to board, and the procedure may be proprietary. It is strongly suggested that anyone wishing to use this driver contact their motherboard vendor, and modify the driver as described in the manual page and in the driver itself. (For what it's worth, the driver as-is has been tested on various SuperMicro motherboards.)

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@.

308664 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.

r308723 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.

Currently linux_common.ko incorporates a code from linux_mib.c and linux_util.c and linprocfs, linsysfs and linux kernel modules depend on linux_common.ko.
Temporarily remove dtrace garbage from linux_mib.c and linux_util.c

Merge from project branch via main. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal.
* An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw.

Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use EVENTHANDLER(mountroot) instead.
This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .
Some policy now needs to be sorted out, and a pre-sync cache needs to be written, but apart from that we are now ready to go.
Over to review.

Snapshot.
Looking pretty good; this mostly works now. New code includes:
* Read cached entropy at startup, both from files and from loader(8) preloaded entropy. Failures are soft, but announced. Untested.
* Use EVENTHANDLER to do above just before we go multiuser. Untested.

SNAPSHOT.
Simplify the malloc pools; We only need one for this device.
Simplify the harvest queue.
Marginally improve the entropy pool hashing, making it a bit faster in the process.
Connect up the hardware "live" source harvesting. This is simplistic for now, and will need to be made rate-adaptive.
All of the above passes a compile test but needs to be debugged.

Snapshot. This passes the build test, but has not yet been finished or debugged.
Contains:
* Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present.
* Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'.

1) Clean up namespace; only use "Yarrow" where it is Yarrow-specific or close enough to the Yarrow algorithm. For the rest use a neutral name.
2) Tidy up headers; put private stuff in private places. More could be done here.
3) Streamline the hashing/encryption; no need for a 256-bit counter; 128 bits will last for long enough.
There are bits of debug code lying around; these will be removed at a later stage.

1) example (partially humorous random_adaptor, that I call "EXAMPLE") * It's not meant to be used in a real system, it's there to show how the basics of how to create interfaces for random_adaptors. Perhaps it should belong in a manual page
2) Move probe.c's functionality in to random_adaptors.c * rename random_ident_hardware() to random_adaptor_choose()
3) Introduce a new way to choose (or select) random_adaptors via tunable "rngs_want" It's a list of comma separated names of adaptors, ordered by preferences. I.e.: rngs_want="yarrow,rdrand"
Such setting would cause yarrow to be preferred to rdrand. If neither of them are available (or registered), then system will default to something reasonable (currently yarrow). If yarrow is not present, then we fall back to the adaptor that's first on the list of registered adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is mostly useful for HW rngs.
The way I envision this is that every HW RNG will use this functionality by default. Functionality to disable this is also present. I have an example of how to use this in random_adaptor_example.c (see modload event, and init function)
5) fix kern.random.adaptors from kern.random.adaptors: yarrowpanicblock to kern.random.adaptors: yarrow,panic,block
6) add kern.random.active_adaptor to indicate currently selected adaptor: root@freebsd04:~ # sysctl kern.random.active_adaptor kern.random.active_adaptor: yarrow

Implement most of timer_{create,settime,gettime,getoverrun,delete} for amd64/linux32. Fix the entirely bogus (untested) version from r161310 for i386/linux using the same shared code in compat/linux.
It is unclear to me if we could support more clock mappings but the current set allows me to successfully run commercial 32bit linux software under linuxolator on amd64.

Merge from project branch via main. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal.
* An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw.

Fix some just-noticed problems:
o Allow this to work with "nodevice random" by fixing where the MALLOC pool is defined.
o Fix the explicit reseed code. This was correct as submitted, but in the project branch doesn't need to set the "seeded" bit as this is done correctly in the "unblock" function.
o Remove some debug ifdeffing.
o Adjust comments.

Time to eat crow for me.
I replaced the sx_* locks that Arthur used with regular mutexes; this turned out the be the wrong thing to do as the locks need to be sleepable. Revert this folly.

Add YARROW_RNG and FORTUNA_RNG to sys/conf/options.
Add a SYSINIT that forces a reseed during proc0 setup, which happens fairly late in the boot process.
Add a RANDOM_DEBUG option which enables some debugging printf()s.
Add a new RANDOM_ATTACH entropy source which harvests entropy from the get_cyclecount() delta across each call to a device attach method.

Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use EVENTHANDLER(mountroot) instead.
This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .
Some policy now needs to be sorted out, and a pre-sync cache needs to be written, but apart from that we are now ready to go.
Over to review.

Snapshot.
Looking pretty good; this mostly works now. New code includes:
* Read cached entropy at startup, both from files and from loader(8) preloaded entropy. Failures are soft, but announced. Untested.
* Use EVENTHANDLER to do above just before we go multiuser. Untested.

Add SWI harvesting to the mix.
My box seeds Yarrow by itself in a few seconds! YMMV; more to follow.

Debug run. This now works, except that the "live" sources haven't been tested. With all sources turned on, this unlocks itself in a couple of seconds! That is no my box, and there is no guarantee that this will be the case everywhere.
* Cut debug prints.
* Use the same locks/mutexes all the way through.
* Be a tad more conservative about entropy estimates.

SNAPSHOT.
Simplify the malloc pools; We only need one for this device.
Simplify the harvest queue.
Marginally improve the entropy pool hashing, making it a bit faster in the process.
Connect up the hardware "live" source harvesting. This is simplistic for now, and will need to be made rate-adaptive.
All of the above passes a compile test but needs to be debugged.

Snapshot. This passes the build test, but has not yet been finished or debugged.
Contains:
* Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present.
* Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'.

Yarrow wants entropy estimations to be conservative; the usual idea is that if you are certain you have N bits of entropy, you declare N/2.

Snapshot of current work;
1) Clean up namespace; only use "Yarrow" where it is Yarrow-specific or close enough to the Yarrow algorithm. For the rest use a neutral name.
2) Tidy up headers; put private stuff in private places. More could be done here.
3) Streamline the hashing/encryption; no need for a 256-bit counter; 128 bits will last for long enough.
There are bits of debug code lying around; these will be removed at a later stage.

1) example (partially humorous random_adaptor, that I call "EXAMPLE") * It's not meant to be used in a real system, it's there to show how the basics of how to create interfaces for random_adaptors. Perhaps it should belong in a manual page
2) Move probe.c's functionality in to random_adaptors.c * rename random_ident_hardware() to random_adaptor_choose()
3) Introduce a new way to choose (or select) random_adaptors via tunable "rngs_want" It's a list of comma separated names of adaptors, ordered by preferences. I.e.: rngs_want="yarrow,rdrand"
Such setting would cause yarrow to be preferred to rdrand. If neither of them are available (or registered), then system will default to something reasonable (currently yarrow). If yarrow is not present, then we fall back to the adaptor that's first on the list of registered adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is mostly useful for HW rngs.
The way I envision this is that every HW RNG will use this functionality by default. Functionality to disable this is also present. I have an example of how to use this in random_adaptor_example.c (see modload event, and init function)
5) fix kern.random.adaptors from kern.random.adaptors: yarrowpanicblock to kern.random.adaptors: yarrow,panic,block
6) add kern.random.active_adaptor to indicate currently selected adaptor: root@freebsd04:~ # sysctl kern.random.active_adaptor kern.random.active_adaptor: yarrow
