The following package has been upgraded in the Cygwin distribution:

* cpuid		20230505

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.

See the project home page for more information:

For information about changes since the previous Cygwin release,
see below or /usr/share/doc/cpuid/ChangeLog after installation.

cpuid.c:

- Fixed bug in (multi-processing synth) in the recently rewritten
  decode_mp_synth(). The CPU counts for higher levels were not dividing
  out counts from lower levels. This is analogous to the way
  print_apic_synth() subtracts out bit widths from lower levels.

- Differentiate Core i3-N300 N-Series from ordinary N-Series. (They
  appear to differ only in branding.)

- Added hypervisor+4/eax bit 21: use hypercalls for MMIO config space
  I/O, based on LX. Not documented by Microsoft yet.

- In real_setup(), make inability to switch to CPU 0 no longer a fatal
  error. It is allowable for CPU 0 to be offlined, just like any other.

- Added (synth) decoding for (0,6),(8,15) Xeon W version of Sapphire
  Rapids, from instlatx64 sample.

- Corrected (synth) & (uarch synth) for Sapphire Rapids: family is
  Golden Cove, not Sunny Cove.

- Added (synth) & (uarch synth) Emerald Rapids family: Raptor Cove.

- Added (synth) & (uarch synth) Granite Rapids family: Redwood Cove.

- In decode_uarch_intel, mark Sapphire Rapids, Emerald Rapids & Granite
  Rapids with core_is_uarch to avoid replicating the name in (synth).

- Added (synth) decoding for (0,6),(10,10),2 Meteor Lake-M B0 from
  Coreboot.
