Various kernel improvements:
-
+ - Added support for the Rockchip RK3568 processor.
+
- Implemented the waitid(2) system call
+ which is now part of POSIX and used by Mozilla.
+
- Introduced clockintr(9), a
+ machine-independent clock interrupt controller. Switched all
+ architectures to use this new kernel subsystem.
+
- Introduced a new kern.autoconf_serial sysctl(8) that can be used
+ by userland to monitor state changes of the kernel device tree.
+
- Fixed pmap(9) bugs
+ involving entering an executable mapping for a page before
+ synchronizing the data and instruction cache on arm64 and riscv64.
+
- Add detection for Spectre-BHB Branch History Injection
+ vulnerability related CLRBHB, ECBHB and CSV2_3/HCXT feature bits.
+
- Add getnsecruntime(9)
+ to the kernel timecounting API. Together with getbinruntime(), it
+ provides a fast, monotonic clock that only advances while the system
+ is not suspended.
+
- Prevent detatching ("bioctl -d detach") of a boot volume on a RAID managed by bioctl(8).
+
- Added WTRAPPED option for waitid(2) to control
+ whether CLD_TRAPPED state changes, i.e., ptrace(2) on a process, are reported.
- On arm64, avoid usin 1GB mappings for the identity map in the
early kernel bootstrap phase and when booting the secondary CPUs. This
avoids accidentally mapping memory regions that should not be mapped
(i.e. secure memory) as all mapped memory can be accessed
speculatively.
-
- Added arm64 detection of EPAN feature bit. Enhanced Privileged Access Never
(EPAN) allows Privileged Access Never to be used with Execute-only mappings.
-
- Removed copystr(9) from public API.

- On arm64, add a machdep.lidaction sysctl(8) for aplsmc(4) Apple Silicon
+ laptops.
+ The arm64 default for the machdep.lidaction is 1, making the
system suspend when the lid is closed. aplsmc(4) provides support
for the lid position sensor.
-
+ - Disable the screen backlight with aplsmc(4) on Apple Silicon
+ laptops when the lid is closed.
- Changed arm64 suspend idle loop from WFE to WFI, avoiding spurious
wakeups while other CPUs are still active.
- Added cursor back tab support to Added a priority queue to clockintr(9).
-
SMP Improvements
-
+ - Unlocked mmap(2), munmap(2), and mprotect(2).
+
- Unlocked sched_yield(2).
+
- Added support for per-cpu event counters, to be used for clock and
+ IPI counters where the event counted occurs across all CPUs in the
+ system.
+
- Moved pf(4) purge
+ tasks out from under the kernel lock.
+
- Unlocked ioctl(2)
+ SIOCGIFCONF, SIOCGIFGMEMB, SIOCGIFGATTR, and SIOCGIFGLIST.
+
- Protected interface tables in pf(4) with PF_LOCK(), allowing
+ removal of NET_LOCK() protection from the ioctl(2) code path in pf.
+
- Unlocked getsockopt(2) and setsockopt(2).
+
- Completed removing kernel lock from IPv6 read ioctls.
+
- Unlocked minherit(2).
- Made tun(4) and tap(4) event filters MP-safe.

VMM/VMD improvements
+ - Updated vmm(4) to
+ allow guests to read MSR_HWCR and MSR_PSTATEDEF, which is necessary to
+ determine the TSC frequency on AMD families 17h and 19h.
+
- Allocated reference for vm and vcpu SLISTs in vmm(4), keeping vmm from
+ triggering excessive wakeup calls while iterating through the list of
+ vms while servicing an ioctl(2).
+
- Set vmm(4) RAX guest
+ register state based on VMCB.
+
- Removed locking in vmm(4) vmm_intr_pending,
+ reducing slowdowns due to requests for a lock held while the VM is
+ running.
+
- Increased speed of delivery of interrupts to a running vcpu in vmm(4).
+
- Made vmm(4) treat vcpu
+ lists as immutable, removing the need to reference count individual
+ vcpu objects and use a rwlock.
- Implemented zero-copy operations on virtqueues in vmd(8).

- Dropped support for $rc_exec in rc.subr(8). The rc_exec

+
- Excluded /tmp/*.shm files from /tmp cleaning in daily(8). Removing them
+ interferes with programs that use shared memory via shm_open(3).

- Added zap-to-char and zap-up-to-char to mg(1). Bound zap-to-char to
