consoleprogram
CPUPRINT.EXE
for
Microsoft®
Windows® NT decodes and prints the
information gathered from the processor’s
CPUID
and XGETBV instructions.
CPUPRINT.LOG
and
CPUPRINT.TXT
show typical outputs for
Intel® Core™
processors;
CPUPRINT.AMD
shows typical output for an
AMD® Athlon™
processor.
Note: CPUPRINT.EXE enumerates the
processor capabilities alias features
IBRS,
STIBP
and
IBPB
as well as the presence of the IA32_ARCH_CAPABILITIES
model specific register, introduced by
AMD
and
Intel
with firmware alias microcode updates to fix the vulnerabilities
CVE-2017-5715
alias Branch Target Injection,
CVE-2017-5753
alias Bounds Check Bypass,
and
CVE-2017-5754
alias Rogue Data Cache Load,
better known by their nicknames
Meltdown
and
Spectre
.
It also enumerates the processor capabilities alias features
PCID,
introduced in first generation Intel Core processors
with Westmere
microarchitecture, and
INVPCID,
introduced in fourth generation Intel Core processors
with Haswell
microarchitecture, both available only in
long mode
, i.e. to 64-bit operating systems, which are
necessary to reduce the performance impact of the fix for
CVE-2017-5754
alias
Meltdown
.
CPUPRINT.NEW
shows the output for an
Intel® Core™ i7-7500U
processor with microcode update applied and all features present.
Note: when started per double-click, i.e. in its
own console
window, CPUPRINT.EXE waits for a
keypress before it exits and its console
window closes; it
beeps once and flashes its console
window to indicate this
wait state.
CPUPRINT.EXE supports multiple specifications of (real
and virtualised) x86 and x64 processors
from several vendors:
CPUPRINT.EXE is a pure Win32
binary executable, written from scratch in
ANSI C,
built without the
MSVCRT
libraries, with the CPUPRINT.EXE is available for the I386
alias x86 and AMD64 alias
x64 processor architectures of
Windows NT.
Note: on the IA64 processor
architecture, the CPUID instruction is supported in
the emulated I386 alias x86 execution
environment only!
Note: CPUPRINT.EXE is neither based
on other outdated tools like
cpuid,
cpuid
or
cpuid
nor related to any of them!
CPUPRINT.EXE
is
digitally signed
using an
X.509
certificate
issued by
WEB.DE TrustCenter E-Mail Certification Authority.

Notes: I dislike
HTML (and
even weirder formats too) in email, I prefer to receive plain text.
I also expect to see a full (real) name as sender, not a nickname!
Emails in weird formats and without a proper sender name are likely
to be discarded.
I abhor top posts and expect inline quotes in replies.
