2020-12-25expose the mcx timer as a timecounter.David Gwynne
this is mostly to help me better understand where i accumulate error when trying to sync the chip to the kernel clocks. ie, if im using mcx as the kernel clock source and my attempts to sync to it still produce errors, then my code is very wrong instead of slightly wrong. it's also fun and a tiny amount of code.

2020-12-25Refactor klist insertion and removalVisa Hankala
Rename klist_{insert,remove}() to klist_{insert,remove}_locked(). These functions assume that the caller has locked the klist. The current state of locking remains intact because the kernel lock is still used with all klists. Add new functions klist_insert() and klist_remove() that lock the klist internally. This allows some code simplification. OK mpi@
2020-12-25Small smr_grace_wait() optimizationVisa Hankala
Make the SMR thread maintain an explicit system-wide grace period and make CPUs observe the current grace period when crossing a quiescent state. This lets the SMR thread avoid a forced context switch for CPUs that have already entered the latest grace period. This change provides a small improvement in smr_grace_wait()'s performance in terms of context switching. OK mpi@, anton@

2020-12-24handle reported core clock frequency of 0 on newer Intel Comet LakeJonathan Gray
The 'nominal core crystal clock frequency' from cpuid 0x15 is 0 on Intel model 0xa5 (CML-H CML-S62 CML-S102) and 0xa6 (CML-U62). So act as if 24 MHz was reported like we do on other Skylake/Kaby Lake variants. Comet Lake processors with model 0x8e (CML-U42 CML-Y42) use the same model number used by Kaby Lake and many other parts which was already handled. While we could approximate the crystal frequency with 'Processor Base Frequency' from cpuid 0x16 eax like FreeBSD and Linux do, kettenis@ couldn't get ntpd to sync a clock on a Skylake machine with: CPUID 0x15: eax=2, ebx=134, khz=0 CPUID 0x16: eax=1600, ebx=1600, ecx=100, edx=0 with reported crystal frequency changing from 24000 kHz to 23880 kHz (cpuid 0x16 eax * 1000 * cpuid 0x15 eax / cpuid 0x15 ebx) and TSC frequency changing from 1608000000 to 1599960000. Cannon Lake, Ice Lake, and Tiger Lake are known to return non-zero frequency in cpuid 0x15 so hopefully no other model ids have to be added. James Cook reported hangs on bsd.rd with i7-10710U 06-a6-00 (CML-U62) (which does not have acpihpet) but not with bsd.mp (which does) and has confirmed that both approaches fixed the problem.
2020-12-24tsleep(9): add global "nowake" channel for threads avoiding wakeup(9)cheloha
It would be convenient if there were a channel a thread could sleep on to indicate they do not want any wakeup(9) broadcasts. The easiest way to do this is to add an "int nowake" to kern_synch.c and extern it in sys/systm.h. You use it like this: #include <sys/systm.h> tsleep_nsec(&nowait, ...); There is now no need to handroll a local dead channel, e.g. int chan; tsleep_nsec(&chan, ...); which expands the stack. Local dead channels will be replaced with &nowake in later patches. One possible problem with this "one global channel" approach is sleep queue congestion. If you have lots of threads sleeping on &nowake you might slow down a wakeup(9) on a different channel that hashes into the same queue. Unsure how much of problem this actually is, if at all. NetBSD and FreeBSD have a "pause" interface in the kernel that chooses a suitable channel automatically. To keep things simple and avoid adding a new interface we will start with this global channel. Discussed with mpi@, claudio@, kettenis@, and deraadt@. Basically designed by kettenis@, who vetoed my other proposals. Bugs caught by deraadt@, tb@, and patrick@.

2020-12-23BGP uses KEEPALIVE packets and the HOLD timer to detect stalled sessions.Claudio Jeker
The problem is that this timer only looks at the receive side of the TCP session. If for some reason the send side stalls the system fully depends on the remote BGP peer to reset the session. As seen in an ever growing OutQ and as a result important changes can get stalled and cause routing troubles. This change introduces a SEND HOLD timer. The timer is reset whenever the session engine was able to write data to the TCP socket. If the send hold timer expires bgpd was not able to send any data to that neighbor for at least 90 seconds and therefor the session is forcefully closed with a hold timer expired notification. The send hold timer acts as a last resort to detect faulty peers. On an idle session it can take a long time until this timer triggers but the main goal here is to reset a stuck session at some point which did not happen before. With and OK job@
