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.
