[PATCH 0/6] x86/cpu: Take Intel platform into account for old microcode checks

[PATCH 0/6] x86/cpu: Take Intel platform into account for old microcode checks

[Dave Hansen]

There was a report[1] that CPUs running updated microcode were being
reported as running old microcode. The reason is that the old
microcode list neglects to take the platform ID into account.

The platform ID is an Intel-only construct that allows CPUs that
otherwise have the same model/family/stepping to take different
microcode revisions. The microcode loader itself already checks this.
Only the recent "old_microcode" checker failed here.

Treat the platform ID as a peer of model/family/stepping. Store it
in 'struct cpuinfo_x86', enable matching on it with with 'struct
x86_cpu_id', and flesh out the 'old_microcode' list with it.

This fixes the report of an inaccurate, false positive in the
'old_microcode' vulnerability file.

[PATCH 1/6] x86/cpu: Break Vendor/Family/Model macros into separate header

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

The intel-family.h header uses Vendor/Family/Model macros but it does not
#include the header where they are defined. If that header is included,
the build blows up in #include hell.

Luckily, these macros are completely independent and do not themselves
have any dependencies on other code.

Break the VFM_*() macros out into their own header.

[PATCH 2/6] x86/cpu: Add missing #include

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

The intel-family.h header uses Vendor/Family/Model macros but it does not
#include the header where they are defined. It must be depending on implicit
includes.

Include the required header explicitly.

[PATCH 3/6] x86/microcode: Refactor platform ID enumeration into a helper

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

The only code that cares about the platform ID is the microcode update
code itself. To facilitate storing the platform ID in a more generic
place and using it outside of the microcode update itself, put the
enumeration into a helper function in a header. Mirror
intel_get_microcode_revision()'s naming and location.

But, moving away from intel_collect_cpu_info() means that the model
and family information in CPUID is not readily available. Just call
CPUID again.

[PATCH 4/6] x86/cpu: Add platform ID to CPU info structure

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

The end goal here is to be able to do x86_match_cpu() and match on a
specific platform ID. While it would be possible to stash this ID
off somewhere or read it dynamically, that approaches would not be
consistent with the other fields which can be matched.

Read the platform ID and store it in cpuinfo_x86->x86_platform_id.

There are lots of sites to set this new field. Place it near
the place c->microcode is established since the platform ID is
so closely intertwined with microcode updates.

Note: This should not grow the size of 'struct cpuinfo_x86' in
practice since the u8 fits next to another u8 in the structure.

[PATCH 5/6] x86/cpu: Add platform ID to CPU matching structure

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

The existing x86_match_cpu() infrastructure can be used to match
a bunch of attributes of a CPU: vendor, family, model, steppings
and CPU features.

But, there's one more attribute that's missing and unable to be
matched against: the platform ID, enumerated on Intel CPUs in
MSR_IA32_PLATFORM_ID. It is a little more obscure and is only
queried during microcode loading. This is because Intel sometimes
has CPUs with identical family/model/stepping but which need
different microcode. These CPUs are differentiated with the
platform ID.

Add a field in 'struct x86_cpu_id' for the platform ID. Similar
to the stepping field, make the new field a mask of platform IDs.
Some examples:

	0x01: matches only platform ID 0x0
	0x02: matches only platform ID 0x1
	0x03: matches platform IDs 0x0 or 0x1
	0x80: matches only platform ID 0x7
	0xff: matches all 8 possible platform IDs

Since the mask is only a byte wide, it nestles in next to another
u8 and does not even increase the size of 'struct x86_cpu_id'.

Reserve the all 0's value as the wildcard (X86_PLATFORM_ANY). This
avoids forcing changes changes to existing 'struct x86_cpu_id' users.
They can just continue to fill the field with 0's and their matching
will work exactly as before.

Note: If someone is ever looking for space in 'struct x86_cpu_id',
this new field could probably get stuck over in ->driver_data
for the one user that there is.

[PATCH 6/6] x86/microcode: Add platform mask to Intel microcode "old" list

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

Intel sometimes has CPUs with identical family/model/stepping but
which need different microcode. These CPUs are differentiated with the
platform ID.

The Intel "microcode-20250512" release was used to generate the
existing contents of intel-ucode-defs.h. Use that same release and add
the platform mask to the definitions.

This makes the list a few entries longer. For example for the ancient
Pentium III there are two CPUs that differ only in their platform and
have two different microcode versions:

	{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x01, .driver_data = 0x40 },
	{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x08, .driver_data = 0x45 },

These CPUs previously shared a definition.  Another example is the
state-of-the-art Granite Rapids:

	{ ...,  .model = 0xad, .steppings = 0x0002, .platform_mask = 0x20, .driver_data = 0xa0000d1 },
	{ ...,  .model = 0xad, .steppings = 0x0002, .platform_mask = 0x95, .driver_data = 0x10003a2 },

As you can see, this differentiation with platform ID has been
necessary for a long time and is still relevant today.

Without the platform matching, the old microcode table is incomplete.
For instance, it might lead someone with a Pentium III, platform 0x0,
and microcode 0x40 to think that they should have microcode 0x45,
which is really only for platform 0x4 (.platform_mask==0x08).

In practice, this meant that folks with fully updated microcode were
seeing "Vulnerable" in the "old_microcode" file.

I made a change to intel-family.h and it broke a parisc config. All
thanks to the PECI header that does:

 #include "../../arch/x86/include/asm/intel-family.h"

in arch-independent code. I'll fix this up in a v2 but reviews on v1 are
still appreciated.

Tail comments are not preferred. I've seen tglx complain about them a few times.

Also, "3 bits" is misleading since x86_platform_id actually stores a bit mask.

Still don't understand why people putting Cc list before the cutter. This noise
in the commit message and when retrospectively one reads on the small screen (I
do on the phone from time to time) it makes it at bare miniumum inconvenient).

There are tabs after #define, is it on purpose?

Reproduce the issue:

On a SPR-SP (F-M-S: 06-8f-08) machine, update the microcode to the
latest 20251111 release:

* v6.19.0-rc6 (w/o this series):

# dmesg | grep microcode
[    0.000000] x86/CPU: Running old microcode
[   20.400144] microcode: Current revision: 0x2b000650
[   20.408038] microcode: Updated early from: 0x2b000461

* v6.19.0-rc6 (with this series):

# dmesg | grep microcode
[   20.499999] microcode: Current revision: 0x2b000650
[   20.507562] microcode: Updated early from: 0x2b000461

The false positive complain about old microcode is fixed on my machine.

I stuck it there because ->platform_mask acts functionally like the

Yeah, you're right. It doesn't fit well with the rest of the structure.
I'll fix it.

Remember, there are two structures in play here. From the cover letter:

This hunk is patching 'cpuinfo_x86' which stores the 3 bits explicitly.

I think you're thinking of the mask in 'x86_cpu_id' which is used for
_matching_ this field in patch 5.

Could you double check that you're asking about the right structure,
please? I've certainly gotten the two structures mixed up before.

By "private", I meant "not cc'd to LKML nor any of the folks on this cc
list". There is a lore link for it, though, which I guess I could have used.

But I mainly wanted to tell the folks who were reading this via LKML or
who were on cc why they didn't see the report. Oh, and one of those
reports was sent *after* I sent this message.

I'd much rather have you look at the code or changelogs!

I was probably going for christmas tree here or something. But,

It's still kinda the wild west, I think.

The usual style to use spaces there. Using tabs makes it mixed and
inconsistent. So the expectation of a define is

#define<single space>$FOO<TAB(s)>$VALUE

Remember, this code is being moved, not newly-composed. It's being moved
for a bug fix and not being "cleaned up" or massaged for other purposes.

In a bug fix series, I tend toward changing as few things as possible.
That includes fixing up whitespace. I apply patches all the time that
move code where that code breaks coding-style.rst in _some_way. I'm more
than happy to ignore the checkpatch warnings there.

I'm also not going to NAK a bug fix that cleans up whitespace. It's
really submitter's preference. _Both_ are fine.

It's really 100% up to the maintainer that applies it. In this case, the
maintainer obviously has a preference, so why belabor the point? ;)

I put stuff above the "---" because I'm a dinosaur using GIT and often use:

	$ git format-patch ....

	...

	$ git am 00*

to rebase, reorder, move bits from one patch to another, or generate a new
version of the series. When I do so the "git am" drops everything after the "---" cut line.

I poked around, but couldn't find any way to make "git am" keep it :-(

BTW... I'm open to other ways of fixing this. This series is bigger than
I'd like. It also crept into silly areas like the PECI driver, which
isn't great.

Using the x86_match_cpu() infrastructure means both munging the
existing, widely-used 'x86_cpu_id' and 'cpuinfo_x86' structures ... all
for what is essentially a single user.

But, the overhead is minimal because both structures had some holes and
the platform_id is small.

It might also have been possible to cram the microcode revision and
platform ID into the ->driver_data in cpu_latest_microcode[]. But that
would not have been straightforward on 32-bit since the kernel_ulong_t
driver_data is full with the microcode revision.

Anyone have any better ideas?

I couldn't imagine why I would need to use this flow for my own changes.
We have rebase, worktree, multiple remotes in one tree, etc. I think
the keyword is 'dinosaur' and now is 21st century :-)

That's the idea, to get them dropped when a maintainer applies the series.
lore.kernel.org will keep the list anyway.

Haven't researched `b4 relay`, maybe that one helps to carry the Cc list on...

See what I put in the parentheses, this is exactly what I admit from

Sure, but it makes no direct visible differences if amended. I don't see
why we would bother with an additional patch to fix white spaces.

It was unclear why you put these two new headers in such an order.
Because it feels like you wanted something like alphabetical, but
something went differently. For the xmas tree I would expect them
still go together

#include <asm/msr.h>
#include <asm/cpu.h>
#include <asm/intel-family.h>

But personally I'm with Chao Gao, the alphabetical is easier to maintain
as it's natural order that many people got for many years starting from
kindergarten times.

Hi Dave,

This patch has:

	c->x86_platform_id = intel_get_platform_id();

but intel_get_platform_id() doesn't return the 3 bits; it returns a
single-bit mask (or 0 on old CPUs).

+{
+	unsigned int val[2];
+
+	/*

I tested this patchset on two machines:

Alder Lake (F-M-S/PI = 06-9a-04/80). The microcode-20251111 from Intel
lists different versions for platform IDs 0x80 and 0x40 of 06-9a-04. Before
these patches, only the machine with platform ID 0x40 would have falsely
complained about the old microcode. Mine did not, as expected. I applied
this patchset and tweaked the file intel-ucode-defs.h to fake a later
microcode version. I could verify that my machine was identified correctly
and distinguished from 06-9a-04/40.

Kaby Lake (F-M-S/PI = 06-8e-09/80). There are two platform IDs for this
model and stepping, but the latest microcode for both is 0xf6. Neither of
these processors would have reproduced the reported false positive. Again,
I tweaked intel-ucode-defs.h with a fake .data_driver value and could
verify that my stepping and platform ID were identified correctly.

Would it be better to use a *native_rdmsrq* and proper #defines instead
of passing the two ints and operating on them using magic values?

I understand the desire to keep this bugfix series as minimal as
possible. But doing this now makes it easier to understand this helper
and what it is returning exactly. That would avoid the confusion in
patch 4 between x86_platform_id and platform_mask.

If you prefer to leave the helper as-is, at a minimum, should we rename
it to intel_get_platform_mask()? Also, the variable name in struct
cpuinfo_x86 should then be x86_platform_mask.

There is an issue in the newly generated list, likely due to a bug in
the generation script. I noticed that some entries are missing.

For example, models 0x46 (Haswell_G) and 0xbe (Alderlake) get deleted in
the diff but do not have a corresponding new entry in the list with
platform ID.

Deleted ones:

[PATCH 6/6] x86/microcode: Add platform mask to Intel microcode "old" list

[Dave Hansen]

From: Dave Hansen <dave.hansen@linux.intel.com>

Intel sometimes has CPUs with identical family/model/stepping but
which need different microcode. These CPUs are differentiated with the
platform ID.

The Intel "microcode-20250512" release was used to generate the
existing contents of intel-ucode-defs.h. Use that same release and add
the platform mask to the definitions.

This makes the list a few entries longer. For example for the ancient
Pentium III there are two CPUs that differ only in their platform and
have two different microcode versions:

	{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x01, .driver_data = 0x40 },
	{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x08, .driver_data = 0x45 },

These CPUs previously shared a definition.  Another example is the
state-of-the-art Granite Rapids:

	{ ...,  .model = 0xad, .steppings = 0x0002, .platform_mask = 0x20, .driver_data = 0xa0000d1 },
	{ ...,  .model = 0xad, .steppings = 0x0002, .platform_mask = 0x95, .driver_data = 0x10003a2 },

As you can see, this differentiation with platform ID has been
necessary for a long time and is still relevant today.

Without the platform matching, the old microcode table is incomplete.
For instance, it might lead someone with a Pentium III, platform 0x0,
and microcode 0x40 to think that they should have microcode 0x45,
which is really only for platform 0x4 (.platform_mask==0x08).

In practice, this meant that folks with fully updated microcode were
seeing "Vulnerable" in the "old_microcode" file.
