Userland timecounter implementation for octeon

2020-07-18T08:37:43Z

OK naddy@; no objections from kettenis@

Add support for timeconting in userland.

2020-07-06T13:33:05Z

This diff exposes parts of clock_gettime(2) and gettimeofday(2) to userland via libc eliberating processes from the need for a context switch everytime they want to count the passage of time. If a timecounter clock can be exposed to userland than it needs to set its tc_user member to a non-zero value. Tested with one or multiple counters per architecture. The timing data is shared through a pointer found in the new ELF auxiliary vector AUX_openbsd_timekeep containing timehands information that is frequently updated by the kernel. Timing differences between the last kernel update and the current time are adjusted in userland by the tc_get_timecount() function inside the MD usertc.c file. This permits a much more responsive environment, quite visible in browsers, office programs and gaming (apparently one is are able to fly in Minecraft now). Tested by robert@, sthen@, naddy@, kmos@, phessler@, and many others! OK from at least kettenis@, cheloha@, naddy@, sthen@

Remove obsolete header. Nowadays the vararg

functionality is provided by using compiler builtins. Tested in a ports bulk build on amd64 by naddy@ OK naddy@ mpi@

Retire .

Nothing uses the header anymore. OK deraadt@ mpi@

Fix some of the more esoteric bus_space functions. The

2020-04-14T17:35:28Z

bus_space_read_region_n, bus_space_write_region_n and bus_space_set_region_n functions were all broken. Same fix as arm64; Thanks to patrick@ for noting that mips64 had the same code. ok visa@

Implement splassert() on mips64.

2019-09-05T05:31:38Z

Adjust interrupt priority levels on mips64 so that priorities

2019-09-05T05:06:33Z

of soft interrupts are lower than priorities of hard interrupts. This allows the delivery of hard interrupts while soft interrupts are masked.

Remove unused spllock().

2018-08-20T15:02:07Z

OK deraadt@ mpi@

Include instead of

2018-01-22T09:40:45Z

required by upcoming MI mutex change.

Add a dummy (for now) for mips64 to fix build.
