Displays detailed information about the CPU(s) gathered from the
CPUID instruction, and also determines the exact model of CPU(s).
Where /proc/cpuinfo shows features important to a system, cpuid shows
what every feature in each CPU's architecture does.
It is updated and released frequently to stay current with Intel and
AMD information and supports other vendors' chips.

The following package has been upgraded in the Cygwin distribution:
- cpuid 20250316
For changes since the previous Cygwin release, see below or
/usr/share/doc/cpuid/ChangeLog after installation.
2025-03-16 cpuid.c
- Updated synth decoding for (0,6),(11,6) to mention Atom P6900, name
determined from an Intel SA about DSA. SSG* confirms that Grand Ridge
is Crestmont.
- Changed uarch synth for (0,6),(10,15) to Crestmont. The Sierra Forest
name appears only under synth decoding, similar to Meteor Lake & Grand
Ridge.
- Added synth decoding for (0,6),(11,7) Xeon E-2400 & Xeon 6300.
- Improved synth decoding for (0,6),(10,15),3 Sierra Forest C0, Xeon 6
6700E-Series.
- Changed synth decoding for (8,15),(9,0-7) Van Gogh to Custom APU:
Steam Deck.
- Changed synth decoding for (8,15),(9,8-15) Mero to Custom APU: Magic
Leap Demophon.
- Changed synth decoding for (11,15),(1,*) to "5th Gen", and uarch
decoding for (11,15),(1,*) to "Zen 5c".
- Changed synth decoding for (10,15),(7,0-7) to be Phoenix/Hawk Point.
For (10,15),(7,5) specifically, instlatx64 has samples: Ryzen 7 8845HS
(Hawk Point) and Ryzen 7 8700G (Phoenix). It may not be possible to
differentiate the cases with just cpuid data.
- Added synth decoding for (0,6),(0,9,2) Timna, a canceled precursor to
Banias, circa 2000.
- Improved synth decoding for (0,6),(12,5) Arrow Lake-H and its A1 (2)
stepping.
- Improved synth decoding for (0,6),(12,6) Arrow Lake-H and its A0/B0
(2) stepping.
- Improved synth decoding for (0,6),(11,5) Arrow Lake-U and its A1 (0)
stepping.
- Added AMD PkgType for Ryzen 9000 (11,15),(4,*).
- cpuid.man: Added 57896 doc.
