Old microcode is bad for users and for kernel developers.
For users, it exposes them to known fixed security and/or functional
issues. These obviously rarely result in instant dumpster fires in
every environment. But it is as important to keep your microcode up
to date as it is to keep your kernel up to date.
Old microcode also makes kernels harder to debug. A developer looking
at an oops need to consider kernel bugs, known CPU issues and unknown
CPU issues as possible causes. If they know the microcode is up to
date, they can mostly eliminate known CPU issues as the cause.
Make it easier to tell if CPU microcode is out of date. Add a list
of released microcode. If the loaded microcode is older than the
release, tell users in a place that folks can find it:
/sys/devices/system/cpu/vulnerabilities/old_microcode
Tell kernel kernel developers about it with the existing taint
flag:
TAINT_CPU_OUT_OF_SPEC
== Discussion ==
When a user reports a potential kernel issue, it is very common
to ask them to reproduce the issue on mainline. Running mainline,
they will (independently from the distro) acquire a more up-to-date
microcode version list. If their microcode is old, they will
get a warning about the taint and kernel developers can take that
into consideration when debugging.
Just like any other entry in "vulnerabilities/", users are free to
make their own assessment of their exposure.
== Microcode Revision Discussion ==
The microcode versions in the table were generated from the Intel
microcode git repo:
8ac9378a8487 ("microcode-20241112 Release")
which as of this writing lags behind the latest microcode-20250211.
It can be argued that the versions that the kernel picks to call "old"
should be a revision or two old. Which specific version is picked is
less important to me than picking *a* version and enforcing it.
This repository contains only microcode versions that Intel has deemed
to be OS-loadable. It is quite possible that the BIOS has loaded a
newer microcode than the latest in this repo. If this happens, the
system is considered to have new microcode, not old.
Specifically, the sysfs file and taint flag answer the question:
Is the CPU running on the latest OS-loadable microcode,
or something even later that the BIOS loaded?
In other words, Intel never publishes an authoritative list of CPUs
and latest microcode revisions. Until it does, this is the best that
Linux can do.
Also note that the "intel-ucode-defs.h" file is simple, ugly and
has lots of magic numbers. That's on purpose and should allow a
single file to be shared across lots of stable kernel regardless of if
they have the new "VFM" infrastructure or not. It was generated with
a dumb script.
== FAQ ==
Q: Does this tell me if my system is secure or insecure?
A: No. It only tells you if your microcode was old when the
system booted.
Q: Should the kernel warn if the microcode list itself is too old?
A: No. New kernels will get new microcode lists, both mainline
and stable. The only way to have an old list is to be running
an old kernel in which case you have bigger problems.
Q: Is this for security or functional issues?
A: Both.
Q: If a given microcode update only has functional problems but
no security issues, will it be considered old?
A: Yes. All microcode image versions within a microcode release
are treated identically. Intel appears to make security
updates without disclosing them in the release notes. Thus,
all updates are considered to be security-relevant.
Q: Who runs old microcode?
A: Anybody with an old distro. This happens all the time inside
of Intel where there are lots of weird systems in labs that
might not be getting regular distro updates and might also
be running rather exotic microcode images.
Q: If I update my microcode after booting will it stop saying
"Vulnerable"?
A: No. Just like all the other vulnerabilies, you need to
reboot before the kernel will reassess your vulnerability.

%p4cc is designed for DRM/V4L2 FourCCs with their specific quirks, but
it's useful to be able to print generic 4-character codes formatted as
an integer. Extend it to add format specifiers for printing generic
32-bit FourCCs with various endian semantics:
%p4ch Host byte order
%p4cn Network byte order
%p4cl Little-endian
%p4cb Big-endian
The endianness determines how bytes are interpreted as a u32, and the
FourCC is then always printed MSByte-first (this is the opposite of
V4L/DRM FourCCs). This covers most practical cases, e.g. %p4cn would
allow printing LSByte-first FourCCs stored in host endian order
(other than the hex form being in character order, not the integer
value).

The FPC202 dual port controller serves as a low speed signal aggregator for
common port types, notably SFP. It provides access to I2C and low-speed
GPIO signals of a downstream device through a single upstream control
interface.
Up to two logical I2C addresses can be accessed on each of the FPC202's
ports. The port controller acts as an I2C translator (ATR). It converts
addresses of incoming and outgoing I2C transactions. One use case of this
is accessing two SFP modules at logical address 0x50 from the same upstream
I2C controller, using two different client aliases.

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:
Recently in the discussion with David the idea of having
a common helper popped up. The helper converts the given
bits per word to bytes. The result will always be power-of-two
(e.g. for 37 bits it returns 8 bytes) or 0 for 0 input.
More details are in the respective code comment.
This mini-series introduces it and replaces current users
under drivers/spi and we expect more (and possibly some
lurking in other subsystems).

Add a DT binding for the Visionox G2647FB105, a 6.47 inch 1080x2340
MIPI-DSI CMD mode AMOLED panel used in:
- Xiaomi Mi Note 10 / CC9 Pro (sm7150-xiaomi-tucana)
- Xiaomi Mi Note 10 Lite (sm7150-xiaomi-toco)
Xiaomi likes to use different panels in various revisions of the same
device. A factory panel even can be replaced with another model in a
service center.
So, the power configuration of this panel is similar to
some Samsung AMOLED panels, e.g. samsung,ams639rq08, which can be found on
other sm7150 Xiaomi devices. Even though Samsung panels weren't used
in sm7150-xiaomi-tucana and toco, the described voltage rails exist
(confirmed by schematics of the device).

Merge series from Julien Massot <julien.massot@collabora.com>:
This patch series adds support for audio playback on the MT8395-based Radxa NIO 12L platform, which uses the integrated MT6359 codec via internal DAI links.
Key additions:
- Support for a new `mediatek,mt8195_mt6359` card configuration that does not rely on external codecs like rt5682.
- Proper memory region declarations and pinctrl setup for the audio front-end (AFE) and audio DSP (ADSP).
- A device tree sound node for headphone audio routing using `DL_SRC_BE` and `AIF1`.
- Enhancements to the DT bindings to document the new compatible string, missing link-name, and additional audio routes (Headphone L/R).

The RTAS call ibm,physical-attestation is used to retrieve
information about the trusted boot state of the firmware and
hypervisor on the system, and also Trusted Platform Modules (TPM)
data if the system is TCG 2.0 compliant.
This RTAS interface expects the caller to define different command
structs such as RetrieveTPMLog, RetrievePlatformCertificat and etc,
in a work area with a maximum size of 4K bytes and the response
buffer will be returned in the same work area.
The current implementation of this RTAS function is in the user
space but allocation of the work area is restricted with the system
lockdown. So this patch implements this RTAS function in the kernel
and expose to the user space with open/ioctl/read interfaces.
PAPR (2.13+ 21.3 ibm,physical-attestation) defines RTAS function:
- Pass the command struct to obtain the response buffer for the
specific command.
- This RTAS function is sequence RTAS call and has to issue RTAS
call multiple times to get the complete response buffer (max 64K).
The hypervisor expects the first RTAS call with the sequence 1 and
the subsequent calls with the sequence number returned from the
previous calls.
Expose these interfaces to user space with a
/dev/papr-physical-attestation character device using the following
programming model:
int devfd = open("/dev/papr-physical-attestation");
int fd = ioctl(devfd, PAPR_PHY_ATTEST_IOC_HANDLE,
struct papr_phy_attest_io_block);
- The user space defines the command struct and requests the
response for any command.
- Obtain the complete response buffer and returned the buffer as
blob to the command specific FD.
size = read(fd, buf, len);
- Can retrieve the response buffer once or multiple times until the
end of BLOB buffer.
Implemented this new kernel ABI support in librtas library for
system lockdown
