      timer: Document TIMER_PINNED · 28ef2db8
      Peter Xu authored
      The flag hints the user that the pinned timers will always be run on a
      static CPU (because that should be what "pinned" means...) but that's
      not the truth, at least with the current implementation.
      
      For example, currently if a pinned timer is set up but later mod_timer()
      upon the pinned timer is invoked, mod_timer() will still try to queue the
      timer on the current processor and migrate the timer if necessary.
      
      Document it a bit with the definition of TIMER_PINNED so that all future
      users will use it correctly.

      clocksource/drivers: Continue making Hyper-V clocksource ISA agnostic · dd2cb348
      Michael Kelley authored
      Continue consolidating Hyper-V clock and timer code into an ISA
      independent Hyper-V clocksource driver.
      
      Move the existing clocksource code under drivers/hv and arch/x86 to the new
      clocksource driver while separating out the ISA dependencies. Update
      Hyper-V initialization to call initialization and cleanup routines since
      the Hyper-V synthetic clock is not independently enumerated in ACPI.
      
      Update Hyper-V clocksource users in KVM and VDSO to get definitions from
      the new include file.
      
      No behavior is changed and no new functionality is added.

      clocksource/drivers: Make Hyper-V clocksource ISA agnostic · fd1fea68
      Michael Kelley authored
      Hyper-V clock/timer code and data structures are currently mixed
      in with other code in the ISA independent drivers/hv directory as
      well as the ISA dependent Hyper-V code under arch/x86.
      
      Consolidate this code and data structures into a Hyper-V clocksource driver
      to better follow the Linux model. In doing so, separate out the ISA
      dependent portions so the new clocksource driver works for x86 and for the
      in-process Hyper-V on ARM64 code.
      
      To start, move the existing clockevents code to create the new clocksource
      driver. Update the VMbus driver to call initialization and cleanup routines
      since the Hyper-V synthetic timers are not independently enumerated in
      ACPI.
      
      No behavior is changed and no new functionality is added.

      arm64: compat: Fix __arch_get_hw_counter() implementation · 6241c4dc
      Vincenzo Frascino authored
      Provide the following fixes for the __arch_get_hw_counter()
      implementation on arm64:
      - Fallback on syscall when an unstable counter is detected.
      - Introduce isb()s before and after the counter read to avoid
      speculation of the counter value and of the seq lock
      respectively.
      The second isb() is a temporary solution that will be revisited
      in 5.3-rc1.
      
      These fixes restore the semantics that __arch_counter_get_cntvct()
      had on arm64.

      lib/vdso: Make delta calculation work correctly · 9d90b93b
      Thomas Gleixner authored
      The x86 vdso implementation on which the generic vdso library is based on
      has subtle (unfortunately undocumented) twists:
      
       1) The code assumes that the clocksource mask is U64_MAX which means that
          no bits are masked. Which is true for any valid x86 VDSO clocksource.
          Stupidly it still did the mask operation for no reason and at the wrong
          place right after reading the clocksource.
      
       2) It contains a sanity check to catch the case where slightly
          unsynchronized TSC values can be observed which would cause the delta
          calculation to make a huge jump. It therefore checks whether the
          current TSC value is larger than the value on which the current
          conversion is based on. If it's not larger the base value is used to
          prevent time jumps.
      
      #1 Is not only stupid for the X86 case because it does the masking for no
      reason it is also completely wrong for clocksources with a smaller mask
      which can legitimately wrap around during a conversion period. The core
      timekeeping code does it correct by applying the mask after the delta
      calculation:
      
      	(now - base) & mask
      
      #2 is equally broken for clocksources which have smaller masks and can wrap
      around during a conversion period because there the now > base check is
      just wrong and causes stale time stamps and time going backwards issues.
      
      Unbreak it by:
      
        1) Removing the mask operation from the clocksource read which makes the
           fallback detection work for all clocksources
      
        2) Replacing the conditional delta calculation with a overrideable inline
           function.
      
      #2 could reuse clocksource_delta() from the timekeeping code but that
      results in a significant performance hit for the x86 VSDO. The timekeeping
      core code must have the non optimized version as it has to operate
      correctly with clocksources which have smaller masks as well to handle the
      case where TSC is discarded as timekeeper clocksource and replaced by HPET
      or pmtimer. For the VDSO there is no replacement clocksource. If TSC is
      unusable the syscall is enforced which does the right thing.
      
      To accommodate to the needs of various architectures provide an
      override-able inline function which defaults to the regular delta
      calculation with masking:
      
      	(now - base) & mask
      
      Override it for x86 with the non-masking and checking version.
      
      This unbreaks the ARM64 syscall fallback operation, allows to use
      clocksources with arbitrary width and preserves the performance
      optimization for x86.

      define and maintain the corresponding asm offsets.
