[PATCH for-4.15 v2 0/3] x86/hpet: Try to unbreak Ryzen 1800X systems

Posted by Andrew Cooper 3 years, 1 month ago

This is a refinement of Jan's "[PATCH][4.15] x86/HPET: don't enable legacy
replacement mode unconditionally" to try and make Xen do the helpful thing on
boot, rather than requiring a non-default command line option to boot in the
first place.

Andrew Cooper (2):
  x86/hpet: Factor hpet_enable_legacy_replacement_mode() out of hpet_setup()
  x86/hpet: Restore old configuration if Legacy Replacement mode doesn't
    help

Jan Beulich (1):
  x86/hpet: Don't enable legacy replacement mode unconditionally
