[PATCH v1 00/12] tools/x86/kcpuid: x86-cpuid-db v2.2 update
From: Ahmed S. Darwish
Date: Thu Mar 06 2025 - 15:51:17 EST
Hi,
This series updates kcpuid's CSV file from v1.0 to v2.2, as generated by
the x86-cpuid-db project. [*]
The CSV changes include:
* New leaves for Transmeta and Centaur/Zhaoxin.
* New bitfields at leaves 0x7, 0x80000001, 0x80000020, and 0x80000021.
* A standardized style for all x86 trademarks, registers, opcodes, byte
units, hexadecimal digits, and x86 technical terms.
More details about the CSV changes are at the actual commit logs.
PQ Summary:
* Patch 1 is a generic kcpuid bugfix.
* Patches 2-4 are preparatory cleanups.
* Patches 5-9 add rudimentary x86 vendor detection and filtering to
kcpuid, as the CSV file is updated with indices that are exclusive to
certain CPU vendors.
* Patch 10 updates the CSV file to x86-cpuid-db v2.0.
* Patch 11 updates the CSV file to x86-cpuid-db v2.2.
Patch 10 and 11 are separate on purpose, to make the CSV commit log
diffs more sensible.
* Patch 12 puts the whole kcpuid tool under MAINTAINERS' X86 CPUID entry,
since changes to the CSV file may require updates to the kcpuid code.
I would also like to have myself and the x86-cpuid mailing list CCed
for all future kcpuid patches.
Thanks!
