* Refactor klist insertion and removalvisa2020-12-251-3/+3
| | | | | | | | | | | | 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@
* alpha, loongson, sh, sparc64: recompute tick, tick_nsec when hz(9) is resetcheloha2020-10-201-1/+3
| | | | | | | | | | | | | | Normally we set hz(9) at compile-time in sys/conf/param.c to the value of HZ. HZ is one of the fundamental compilation options(4). However, sometimes we need to reset hz(9) at runtime. Whenever we reset hz(9) we need to recompute tick and tick_nsec. Otherwise a variety of "time stuff" in the kernel will not work correctly. For example, most timeouts will expire "too slow" or "too fast". There are a bunch of other places we use tick and tick_nsec that will exhibit similar problems. Test-compiled by deraadt@.

| | | | | | | | | | | platforms than just loongson. Rename it to mfokrtc(4) for consistency with other RTC drivers. Make it match on st,m41t83, since that was the chip for which the driver was written for. More compatible strings can be added for each chip of the series verified to behave the same.

* kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9)cheloha2020-06-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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@

| | | | | | | | | it assumes that it always followed an interrupt string, but we don't print that on fdt. having the bus responsible for the whitespace means the fdt glue can print a colon to separate the bus info from checkrev output, while every other glue keeps the comma. ok deraadt@
* Declare ci_ipl volatile to prevent the compiler from optimizingvisa2018-02-241-7/+1
| | | | | | | | | | | | | | | | | | or reordering accesses to the variable. Assume that the assembler preserves the correct sequence of instructions, which allows the removal of the explicit noreorder/reorder toggles from the C code. With ci_ipl being volatile, drop mips_sync() calls that follow the accesses of the variable. The sync is redundant as a compiler barrier. In addition, the MIPS64 CPU designs should not need the sync for pipeline or write buffer control. According to miod@, the use of the instruction is a carryover from code targeting early MIPS designs that lack tight integration with the cache and write buffer. Discussed with and testing help from miod@. Tested on CN5020, CN6120, CN7130, CN7360, Loongson 2F and 3A1000, R4400, R8000, R10000 and R16000.
