Re-work intr_barrier(9) on arm64 to remove layer violation. So far we

have stored the struct cpu_info * in the wrapper around the interrupt handler cookie, but since we can have a few layers inbetween, this does not seem very nice. Instead have each and every interrupt controller provide a barrier function. This means that intr_barrier(9) will in the end be executed by the interrupt controller that actually wired the pin to a core. And that's the only place where the information is stored. ok kettenis@

Extend the interrupt API on arm64 and armv7 to be able to pass around

2020-07-14T15:34:14Z

a struct cpu_info *. From a driver point of view the fdt_intr_establish_* API now also exist same functions with a *_cpu suffix. Internally the "old" functions now call their *_cpu counterparts, passing NULL as ci. NULL will be interpreted as primary CPU in the interrupt controller code. The internal framework for interrupt controllers has been changed so that the establish methods provided by an interrupt controller function always takes a struct cpu_info *. Some drivers, like imxgpio(4) and rkgpio(4), only have a single interrupt line for multiple pins. On those we simply disallow trying to establish an interrupt on a non-primary CPU, returning NULL. Since we do not have MP yet on armv7, all armv7 interrupt controllers do return NULL if an attempt is made to establish an interrupt on a different CPU. That said, so far there's no way this can happen. If we ever gain MP support, this is a reminder that the interrupt controller drivers have to be adjusted. Prompted by dlg@ ok 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@

Define __HAVE_ACPI on arm64 and __HAVE_FDT on arm64, armv7 and octeon

2018-08-09T12:19:32Z

so that we can include firmware-dependant code in generic drivers to be able to extract metadata information like MAC addresses and out-of-band interrupts from the ACPI/FDT tables. ok kettenis@
