Chagnes from v3:
* Fix handling of the Pentium II's "no platform" goofiness.
Note: this was found in a Github Copilot review of the
series. I wrote the solution.
* Rebase to 7.0-rc2
Changes from v2:
* Move new helpers from .h into .c file. This avoids the
#include dependency issues for now. That can be dealt
with another day.
* Rename x86_platform_id to have an intel_ prefix and add a
union to make it clear that AMD can use the space for
something else
Changes from v1:
* Fix non-x86 PECI compile issues by lifting some x86 macros
into an arch-independent header.
* Make intel_get_platform_id() match its name and return an ID,
not a mask.
* Sort #includes
* Move ->x86_platform_id comment
The platform ID vs. platform mask confusion meant that v1
worked by total accident. If you tested v1, I'd really
appreciate you retest this as well.

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.

From: Dave Hansen <dave.hansen@linux.intel.com>
Today, 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. 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.
Note that the microcode header is a mask of supported platform IDs.
Only stick the ID part in the helper. Leave the 1<<id part in the
microcode handling.
Also note that the PII is weird. It does not really have a platform
ID because it doesn't even have the MSR. Just consider it to be
platform ID 0. Instead of saying >=PII, say <=PII. The PII is the
real oddball here being the only CPU with Linux microcode updates
but no platform ID. It's worth calling it out by name.
This does subtly change the sig->pf for the PII though from 0x0
to 0x1. Make up for that by ignoring sig->pf when the microcode
update platform mask is 0x0.

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.
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.

initialization from generic code
* Add a amd_unused so it's clear the AMD folks have a
free field to play with.

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 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.

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 because some CPUs previously
that shared a definition now need two or more. for example for the
ancient Pentium III there are two CPUs that differ only in their
platform and have two different microcode versions (note:
.driver_data is the microcode version):
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x01, .driver_data = 0x40 },
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x08, .driver_data = 0x45 },
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.

Just want to make sure that c->intel_platform_id not getting explicitly
initialized for !CONFIG_CPU_SUP_INTEL is okay. I believe it is fine because
the global boot_cpu_data should be zero-initialized.
I see model and stepping are being initialized in identify_cpu(), but I
don't see any vendor specific initialization here:
identify_cpu()
{
int i;
c->loops_per_jiffy = loops_per_jiffy;
c->x86_cache_size = 0;
c->x86_vendor = X86_VENDOR_UNKNOWN;
c->x86_model = c->x86_stepping = 0; /* So far unknown... */

What Dave has here is correct. You can blame me for the confusion.
Family 6, model 5 is DESCHUTES but Pentium II and not III.
I incorrectly named it INTEL_PENTIUM_III_DESCHUTES in commit
7e6b0a2e4152 ("x86/microcode: Update the Intel processor flag scan
check"). It should have been named INTEL_PENTIUM_II_DESCHUTES.
Anyway, there are no other users of this. So after this series merges
I'll send a cleanup patch deleting the #define completely.

Use the full length of 80-ish cols:

That helper looks pretty generic. We should remember to pull it up if we end
up needing it somewhere else...
Otherwise, LGTM.

It's debatable. It's nice having the 'sig' explain what's in EAX. But
'sig' is pretty generic and the code is all right here anyway. I think
I'll leave it as 'eax'.

Yeah, I believe it's OK. The model/stepping initialization is probably
unnecessary in the first place, and all of the Intel code that use the
platform IDs will have set it properly.

x86/microcode: Add platform mask to Intel microcode "old" list
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 because some CPUs previously
that shared a definition now need two or more. for example for the
ancient Pentium III there are two CPUs that differ only in their
platform and have two different microcode versions (note:
.driver_data is the microcode version):
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x01, .driver_data = 0x40 },
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x08, .driver_data = 0x45 },
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.

x86/cpu: Add platform ID to CPU matching structure
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 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.

x86/cpu: Add platform ID to CPU info structure
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.
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.
--
Changes from v2:
* rename x86_platform_id=>intel_platform_id and remove
initialization from generic code
* Add a amd_unused so it's clear the AMD folks have a
free field to play with.

x86/microcode: Refactor platform ID enumeration into a helper
Today, 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. 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.
Note that the microcode header is a mask of supported platform IDs.
Only stick the ID part in the helper. Leave the 1<<id part in the
microcode handling.
Also note that the PII is weird. It does not really have a platform
ID because it doesn't even have the MSR. Just consider it to be
platform ID 0. Instead of saying >=PII, say <=PII. The PII is the
real oddball here being the only CPU with Linux microcode updates
but no platform ID. It's worth calling it out by name.
This does subtly change the sig->pf for the PII though from 0x0
to 0x1. Make up for that by ignoring sig->pf when the microcode
update platform mask is 0x0.

x86/microcode: Add platform mask to Intel microcode "old" list
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 because some CPUs previously
that shared a definition now need two or more. for example for the
ancient Pentium III there are two CPUs that differ only in their
platform and have two different microcode versions (note:
.driver_data is the microcode version):
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x01, .driver_data = 0x40 },
{ ..., .model = 0x05, .steppings = 0x0001, .platform_mask = 0x08, .driver_data = 0x45 },
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.

x86/cpu: Add platform ID to CPU matching structure
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 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.

x86/cpu: Add platform ID to CPU info structure
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.
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.

x86/microcode: Refactor platform ID enumeration into a helper
Today, 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. 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.
Note that the microcode header is a mask of supported platform IDs.
Only stick the ID part in the helper. Leave the 1<<id part in the
microcode handling.
Also note that the PII is weird. It does not really have a platform
ID because it doesn't even have the MSR. Just consider it to be
platform ID 0. Instead of saying >=PII, say <=PII. The PII is the
real oddball here being the only CPU with Linux microcode updates
but no platform ID. It's worth calling it out by name.
This does subtly change the sig->pf for the PII though from 0x0
to 0x1. Make up for that by ignoring sig->pf when the microcode
update platform mask is 0x0.
