  In preparation for the x86_64 generic time conversion, this patch splits out
  TSC and HPET related code from arch/x86_64/kernel/time.c into respective
  hpet.c and tsc.c files.

• 2d0c87c3b   [PATCH] time: x86_64: hpet_address cleanup ... Browse Code »

  In preparation for supporting generic timekeeping, this patch cleans up
  x86-64's use of vxtime.hpet_address, changing it to just hpet_address as is
  also used in i386. This is necessary since the vxtime structure will be going
  away.

  Rename oem_force_hpet_timer to apic_is_clustered_box, to give the
  function a better fitting name - it really isn't at all about HPET.

  If the HPET timer is enabled, the clock can drift by ~3 seconds a day.
  This is due to the HPET timer not being initialized with the correct
  setting (still using PIT count).

  If HZ changes, this drift can become even more pronounced.

  HPET patch initializes tick_nsec with correct tick_nsec settings for
  HPET timer.

  Vojtech comments:

  "It's not entirely correct (it assumes the HPET ticks totally
  exactly), but it's significantly better than assuming the PIT error
  there."

  [description from AK]

  The IBM Summit 3 chipset doesn't implement the HPET timer replacement
  option. Since the current Linux code relies on it use a mixed mode with
  both PIT for the interrupt and HPET counters for the time keeping. That
  was already implemented, but didn't work properly because it was still
  using the last interrupt offset in HPET. This resulted in x460 not
  booting. Fix this up by using the free running HPET counter.

  Shouldn't affect any other machine because they either use full HPET mode
  or no HPET at all.

  TBD needs a similar 32bit fix.

  Initial git repository build. I'm not bothering with the full history,
  even though we have it. We can create a separate "historical" git
  archive of that later if we want to, and in the meantime it's about
  3.2GB when imported into git - space that would just make the early
  git days unnecessarily complicated, when we don't have a lot of good
  infrastructure for it.

  Let it rip!
