Subject: Updated: cpuid 20240330
Date: Sat, 06 Apr 2024 22:42:11 -0600	[thread overview]
Message-ID: <20240406224211.56152-1-Brian.Inglis@SystematicSW.ab.ca> (raw)

The following package has been upgraded in the Cygwin distribution:

* cpuid		20240330

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.


2024 Mar 30 Sat		20240330

cpuid.man:

- Added new Intel 355828 (APX) doc.

cpuid.c:

- Added 5/ecx monitorless MWAIT.
- Added 7/1/edx user-timer events.
- Added 7/1/edx AVX10 instructions.
- Added 7/1/edx APX advanced performance extensions.
- Added 7/1/edx MWAIT instruction (overrides 1/ecx[3]).
- Added Intel-specific print_instr_synth_intel to determine presence of
  MWAIT from 1/ecx and/or 7/1/edx.
- Updated 12/n/ecx section property values 1 & 3.
- Added 14/0/ebx PTTT processor trace trigger tracing.
- Added 14/1/eax number of IA32_RTIT_TRIGGERx_CFG MSRs, including
  D4_IMAGES decoding.
- Added 14/1/ecx flags.
- Added MINUS24_IMAGES decoding for 0xf/1/eax QoS monitoring counter
  size.
- Added 0x23/1 sub-header: Architecture Performance Monitoring Extended
  Counters Supported Bitmaps (0x23/1), and simplified fields.
- Added 0x23/2 sub-header: Architecture Performance Monitoring Extended
  Auto Counter Reload (ACR) Bitmaps (0x23/2), expanded on existing field
  descriptions, and added "can cause reloads" fields.
- Added 0x24 leaf: Converged Vector ISA.
- Added to print_d_n: new XSAVE area: 19 for APX EPGR
   general purpose registers.
- Added uarch decoding for (11,15),(1,0), which is mentioned with
  (11,15),(0,0) in the title of 58088 AMD 1Ah Models 00h-0Fh and Models
  10h-1Fh ACPI v6.5 Porting Guide.
- Expanded br.xeon test to include brands with "XEON", and br.scalable
  to include "BRONZE", "PLATINUM", etc. (all caps), based on Emerald
  Rapids (engr?) sample. I don't know if this is a change Intel will
  use moving forward, or a quirk of engr samples, but checking for it is
  harmless enough.
