Allow counters_read(9) to take an optional scratch buffer. Using a scratch buffer makes it possible to take a consistent snapshot of per-CPU counters without having to allocate memory. Makes ddb(4) show uvmexp command work in OOM situations. ok kn@, mvs@, cheloha@

schedcpu, uvm_meter(9): make uvm_meter() an independent timeout uvm_meter(9) should not base its periodic uvm_loadav() call on the UTC clock. It also no longer needs to periodically wake up proc0 because proc0 doesn't do any work. schedcpu() itself may change or go away, but as kettenis@ notes we probably can't completely remove the concept of a "load average" from OpenBSD, given its long Unix heritage. So, (1) remove the uvm_meter() call from schedcpu(), (2) make uvm_meter() an independent timeout started alongside schedcpu() during scheduler_start(), and (3) delete the vestigial periodic proc0 wakeup. With input from deraadt@, kettenis@, and claudio@. deraadt@ cautions that this change may confuse administrators who hold the load average in high regard. Thread: https://marc.info/?l=openbsd-tech&m=168710929409153&w=2 general agreement with this direction from kettenis@ ok claudio@

kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9) time_second(9) and time_uptime(9) are widely used in the kernel to quickly get the system UTC or system uptime as a time_t. However, time_t is 64-bit everywhere, so it is not generally safe to use them on 32-bit platforms: you have a split-read problem if your hardware cannot perform atomic 64-bit reads. This patch replaces time_second(9) with gettime(9), a safer successor interface, throughout the kernel. Similarly, time_uptime(9) is replaced with getuptime(9). There is a performance cost on 32-bit platforms in exchange for eliminating the split-read problem: instead of two register reads you now have a lockless read loop to pull the values from the timehands. This is really not *too* bad in the grand scheme of things, but compared to what we were doing before it is several times slower. There is no performance cost on 64-bit (__LP64__) platforms. With input from visa@, dlg@, and tedu@. Several bugs squashed by visa@. ok kettenis@

Stop considering some sleeping threads are running. PZERO used to be a special value in the first BSD releases but since the introduction of tsleep(9) there's no way to tell if a thread is going to sleep for a "short" period of time. This remove the only (ab)use of ``p_priority'' outside the scheuler logic, which will help moving avway from a priority-based scheduler. ok visa@

Move ps_strings "after" the random stackgap. This makes its location a per-process value, and therefpore turns the VM_PSSTRINGS sysctl into a per-process one as well.

Include <sys/vmmeter.h> directly instead of relying on it being pulled by <uvm/uvm_extern.h> and turn uvm_total() into a private function. The preferred way to get memory stats is through the VM_UVMEXP sysctl(3) since VM_METER is just a wrapper on top of it. In the kernel, use `uvmexp' directly instead of uvm_total(). This change does not remove <sys/vmmeter.h> from <uvm/uvm_extern.h> to give some more time to port maintainers to fix their ports. ok guenther@ as part of a larger diff.

Make context switching much more MI: - Move the functionality of choosing a process from cpu_switch into a much simpler function: cpu_switchto. Instead of having the locore code walk the run queues, let the MI code choose the process we want to run and only implement the context switching itself in MD code. - Let MD context switching run without worrying about spls or locks. - Instead of having the idle loop implemented with special contexts in MD code, implement one idle proc for each cpu. make the idle loop MI with MD hooks. - Change the proc lists from the old style vax queues to TAILQs. - Change the sleep queue from vax queues to TAILQs. This makes wakeup() go from O(n^2) to O(n) there will be some MD fallout, but it will be fixed shortly. There's also a few cleanups to be done after this. deraadt@, kettenis@ ok

Kernel stack can be swapped. This means that stuff that's on the stack should never be referenced outside the context of the process to which this stack belongs unless we do the PHOLD/PRELE dance.

Merge in -current from two days ago in the SMP branch. As usual with merges, they do not indicate progress, so do not hold your breath for working SMP, and do not mail me and ask about the state of it. It has not changed. There is work ongoing, but very, very slowly. The commit is done in parts as to not lock up the tree in too big chunks at a time.

Convert bzero to memset(X, 0..) and bcopy to memcpy. This is to match (make diffs smaller) the code in NetBSD. new gcc inlines those functions, so this could also be a performance win.

swap encryption for UVM, option UVM_SWAP_ENCRYPT. needs to be enabled via sysctl. Pages are encrypted with the Blowfish encryption algorithm, the key is initialized randomly on first swap out, ensuring that entropy has accumulated in the kernel randomness pool. Eventually, swap encryption will be decided on a process by process basis, e.g. a process that reads from a cryptographic filesystem will enable swap encrypt for its pages. okay art@ and deraadt@.
