| H A D | cpu.h | diff 340270 Thu Nov 08 22:58:43 MST 2018 jhb MFC 340164,340168,340170: Add custom cpu_lock_delay() for x86. 340164: Add a KPI for the delay while spinning on a spin lock. Replace a call to DELAY(1) with a new cpu_lock_delay() KPI. Currently cpu_lock_delay() is defined to DELAY(1) on all platforms. However, platforms with a DELAY() implementation that uses spin locks should implement a custom cpu_lock_delay() doesn't use locks. 340168: Add a delay_tsc() static function for when DELAY() uses the TSC. This uses slightly simpler logic than the existing code by using the full 64-bit counter and thus not having to worry about counter overflow. 340170: Add a custom implementation of cpu_lock_delay() for x86. Avoid using DELAY() since it can try to use spin locks on CPUs without a P-state invariant TSC. For cpu_lock_delay(), always use the TSC if it exists (even if it is not P-state invariant) to delay for a microsecond. If the TSC does not exist, read from I/O port 0x84 to delay instead.
