GPL-2.0-or-later
* Wed Oct 23 2024 Jan Engelhardt <jengelh@inai.de>
- Update to release 20241021
* Recognition for some Intel Arrow Lake-U, Nova Lake, Core
200S, Core 200V, Xeon 6 Sierra Forest models.
* Removed KaiXian KX-7000.
* Mon Aug 05 2024 Valentin Lefebvre <valentin.lefebvre@suse.com>
- Update to release 20240716
* cpuid.c: For AMD Zen CPUs, overhauled uarch & synth decoding to
determine the CPU model from only the extended model & high bit of the
model field. Also, determine the stepping (revision) mechanically
from the low-order 3 bits of the model and the stepping number.
This should correctly identify retail Zen 5 Ryzen's. This also
corrects some stepping bugs from the Zen 1 era.
- Update to release 20240709
* cpuid.c: Added synth decoding for Hygon Dhyana B1 & C2. Still no
information on a uarch name for these.
* cpuid.c: Added uarch synth decoding for (0,6),(5,5),11 Cooper Lake.
The synth decoding was already present. Its absence from
decode_uarch_intel was just an oversight.
* cpuid.c: Fixed division-by-zero error in decode_mp_synth Intel leaf
1/4 (zero fallback). This is meant for old, incomplete cpuid -r
dumps, but even for hand-crafted dumps, determining 0 cores and then
dividing by that 0 is unacceptable.
- Update to release 20240330
* cpuid.c: Added 0x23/1 sub-header: Architecture Performance Monitoring
Extended Counters Supported Bitmaps (0x23/1), and simplified fields.
* cpuid.c: 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.
* cpuid.c: 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.
* cpuid.c: 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.
- Update to release 20240324
* cpuid.c: Updated (0,6),(11,7) to include Core i*-14000. Some CPUs
having this branding, and it's not clear what's different from the
Core i*-13000 versions.
* Wed Jun 21 2023 Valentin Lefebvre <valentin.lefebvre@suse.com>
- Update to release 20230614
* Improved (synth) identification for Intel Xeon Scalable (3rd
Gen) (Cooper Lake A0), Intel Xeon D-1700/2700 (Ice Lake-D),
Intel Pentium Gold 8500 series, pure Atom x7000E, Atom C1100
Arizona Beach.
* Made the (simple synth) fields non-default. The (simple synth)
fields still are available, but only with the -S/--simple
option.
- Update to release 20230505
* Fixed CPU counts for higher levels
not dividing out counts from lower levels.
* Differentiate Core i3-N300 N-Series from ordinary N-Series.
* Added hypervisor+4/eax bit 21: use hypercalls for MMIO config
space I/O, based on LX*.
* Added (synth) decoding for Xeon W version of Sapphire Rapids,
Meteor Lake-M B0.
* Added (synth) & (uarch synth) Emerald Rapids family: Raptor
Cove, and Granite Rapids family: Redwood Cove.
* Fri Apr 14 2023 Egbert Eich <eich@suse.com>

the AMD Processor Programming Reference for Family 19h and
Model 11h: extended LVT offset fault cange, enhanced
predictive store forwarding, FSRS, FSRC,
FsGsKernelGsBaseNonSerializing, number of available UMC PMCs,
bitmask representing active UMCs.
* Added (synth) decoding for Sapphire Rapids D & E0 steppings
* Improved (synth) decoding for Scalable 3rd Gen Xeons to Ice
Lake-SP, for Intel N-Series, for Raptor Lake-S/HX/P, for

Alder Lake-N based on core type.

* Added (4th Gen) to the (synth) description of AMD EPYC Genoa.

* Added PkgType decoding for AMD Family 19h CPUs: Vermeer,
Cezanne/Barcelo, Raphael, and Phoenix, based on their
respective PPPRs.
* Added Alder Lake Core names: i*-12000.
* Decode Xen tsc mode.
* Sat Jan 28 2023 Dirk Müller <dmueller@suse.com>
- updated to 20230120:
* Intel's 13th Generation Core datasheet provides stepping names as
well as numbers! So:
* cpuid.c: Added synth decoding for (0,6),(11,7) Raptor Lake B0 stepping.
* cpuid.c: Added synth decoding for (0,6),(11,15) Raptor Lake C0
steppings, and clarified case for unknown stepping.
* cpuid.man: Added 743844: 13th Generation Core datasheet.
* cpuid.c: Fixed (0,6)(12,15) synth typo: Emearld Rapids.
* cpuid.c: Added 6/eax IA32_HW_FEEDBACK_THREAD_CONFIG bit 25.
* cpuid.c: Added 7/0/edx SGX-KEYS: SGX attestation services.
* cpuid.c: Clarified 7/0/edx IA32_MCU_OPT_CTRL SRBDS mitigation MSR.
* cpuid.c: Clarified 7/0/edx IA32_TSX_FORCE_ABORT MSR.
* cpuid.c: Added 7/1/edx CET_SSS: shadow stacks w/o page faults.
* cpuid.c: Added several 7/2/edx bits.
* cpuid.c: In 0xd/0/eax, corrected CET_U & CET_S, which were IA32_XSS.
* cpuid.c: In 0xd/0/eax, removed the IA32_XSS bits, which aren't
relevant for XCR0.
* cpuid.c: For 0xd/1/ecx, enumerate the IA32_XSS bits instead of a
hex bitmask.
* cpuid.c: For 0xd, added IA32_XSS PASID state (couple places).
* cpuid.c: Renamed 0x1a: Native Model ID.
* cpuid.c: Added synth & uarch decoding for (0,6),(11,15) Raptor Lake
from MSR_CPUID_table*.
* cpuid.c: Added synth decoding for (0,6),(9,7),5 Pentium Gold G7400,
based on instlatx64 sample.
* cpuid.c: Added rudimentary synth decoding for future (0,6),(12,15)
Emerald Rapids CPUs.
* cpuid.c: Added 7/1/eax LASS: linear address space separation.
* cpuid.c: Corrected 0x18/n/edx maximum number of addressible IDs, which
should use minus-one notation.
* cpuid.c: Certain leaves cannot be displayed correctly in isolation,
i.e. without information about other leaves saved in the stash. For
example, the display for leaf 3 uses bits saved from leaf 1. If the
- l/--leaf option is used to restrict cpuid to reading only a single
leaf, such leaves now are displayed as raw hex, rather than with
incorrect information. This is handled by passing a NULL stash to
print_reg() and below, and by many new checks for a NULL stash.
* cpuid.c: Updated cache associativity strings used in 0x80000006 and
0x80000019 leaves to use value ranges, as in AMD docs.
* cpuid.c: Fixed mistake in AMD L3 range reservation support: it's in
0x80000020/0 register EBX, not ECX.
* cpuid.c: Added 0x80000026/0/edx extended APIC ID.
* cpuid.c: Added synth & uarch decoding for (10,15),(1,1) Genoa, from
AMD 57095 revision guide.
* cpuid.man: Added AMD 57095 revision guides, and some older guides that
I'd forgotten.
