The following package has been updated in the Cygwin distribution:

* cpuid 20201006

The program displays detailed information about the CPU(s) gathered from
the CPUID instruction, and also determines the exact model of CPU(s).

Whereas /proc/cpuinfo is like an abstract of the features important to
Linux in a system, cpuid is a standalone utility which writes a paper
expounding on every feature in each CPU's architecture and what it can
do, at about the one line per bit level.

It is updated and released frequently and appears current with Intel and
AMD info and supports other vendors' chips.


Added latest Intel and AMD features and added, corrected, or clarified
(synth) decoding for:

* Intel (0,6),(10,6) Comet Lake, Rocket Lake, Elkhart Lake B0, Alder
  Lake [Golden Cove], (0,6),(8,10) Lakefield, Tiger Lake-U B0 stepping,
  Comet Lake-H/S Core i*-10000;

* AMD (7,5),(2,6) Cato, (8,15),(2,0) Dali, Dali A1 stepping, Picasso A1
  stepping, Renoir A1 stepping, (8,15),(2,0) Picasso;

* Zhaoxin KX-6000 that still claims the vendor CentaurHauls;

Detect bogus 0x20000000 leaf values and cap the maximum valid register
to avoid absurdly long dumps on old CPUs.
