Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).
As proposed in LPC 2025 and the Maintainers Summit [1], we are
going to follow Debian Stable's Rust versions as our minimum
versions.
Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.
Other major distributions support a Rust version that is high
enough as well, including:
+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.
The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both
bumps, as well as documentation updates.
In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status'
enum used in Binder.
Link: https://lwn.net/Articles/1050174/ [1]
- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.
Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.
It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major
version, 'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled
for two architectures for now.
The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block
driver, it amounts to a 2%.
- Support global per-version flags.
While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler
version, i.e. in 'rust_common_flags', which sometimes is needed to
e.g. tweak the lints set per version.
Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.
- Support overriding the crate name and apply it to Rust Binder,
which wanted the module to be called 'rust_binder'.
- Add the remaining '__rust_helper' annotations (started in the
previous cycle).
'kernel' crate:
- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:
fn f<const N: usize>() {
const_assert!(N > 1);
}
fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}
In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.
Finally, improve the docs as well to clarify how these are
different from one another and how to pick the right one to use,
and their equivalence (if any) to the existing C ones for extra
clarity.
- 'sizes' module: add 'SizeConstants' trait.
This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the
hardware (e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.),
e.g.:
let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;
- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus
simplify the users in Tyr and PWM.
- 'ptr' module: add 'const_align_up'.
- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').
- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such
use in the 'task' module.
- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.
- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.
The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a
case of UB I noticed in 'regulator' that created a 'NonNull' on it.
Timekeeping:
- Expand the example section in the 'HrTimer' documentation.
- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.
- Add 'Delta::from_nanos()'.
'pin-init' crate:
- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.
- Improve feature gate handling for unstable features.
- Declutter the documentation of implementations of 'Zeroable' for
tuples.
- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.
rust-analyzer:
- Add type annotations to 'generate_rust_analyzer.py'.
- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').
- Refactor 'generate_rust_analyzer.py' to explicitly identify host
and target crates, improve readability, and reduce duplication.
And some other fixes, cleanups and improvements"

A job timeout does not necessarily indicate that the device is hung, as
it may still be processing other jobs.
Track whether any jobs have been successfully submitted or completed,
and use this information to determine if the device is making forward
progress. If so, return DRM_GPU_SCHED_STAT_NO_HANG instead of treating
the timeout as a device hang.
In the meanwhile the timeout interval is changed to 2 seconds which meets
the userspace requirement.

In order to unify the handling of the panel and bridge, apply
panel_bridge helpers for Analogix DP driver. With this patch, the
bridge support will also become available.
The following changes have ben made:
- Apply plane_bridge helper to wrap the panel as the bridge.
- Remove the explicit panel APIs calls, which can be replaced with
the automic bridge APIs calls wrapped by the panel.
- Remove the unnecessary analogix_dp_bridge_get_modes().

analogix_dp_unbind()
The analogix_dp_unbind() should be balanced with analogix_dp_bind().
There are no bridge enabling and panel preparing in analogix_dp_bind(),
so it should be reasonable to remove the bridge disabing and panel
unpreparing in analogix_dp_unbind().

Since the panel/bridge should logically be positioned behind the
Analogix bridge in the display pipeline, it makes sense to handle
the panel/bridge parsing on the Analogix side. Therefore, we add
a new API analogix_dp_finish_probe(), which combines the panel/bridge
parsing with component addition, to do it.
In order to process component binding right after the probe completes,
the &analogix_dp_plat_data.ops is newly added to pass &component_ops,
for which the &dp_aux_ep_device_with_data.done_probing() of DP AUX bus
only supports passing &drm_dp_aux.

This series cleans up some of the special user copy functions naming and
semantics. In particular, get rid of the (very traditional) double
underscore names and behavior: the whole "optimize away the range check"
model has been largely excised from the other user accessors because
it's so subtle and can be unsafe, but also because it's just not a
relevant optimization any more.
To do that, a couple of drivers that misused the "user" copies as kernel
copies in order to get non-temporal stores had to be fixed up, but that
kind of code should never have been allowed anyway.
The x86-only "nocache" version was also renamed to more accurately
reflect what it actually does.
This was all done because I looked at this code due to a report by Jann
Horn, and I just couldn't stand the inconsistent naming, the horrible
semantics, and the random misuse of these functions. This code should
probably be cleaned up further, but it's at least slightly closer to
normal semantics.
I had a more intrusive series that went even further in trying to
normalize the semantics, but that ended up hitting so many other
inconsistencies between different architectures in this area (eg
'size_t' vs 'unsigned long' vs 'int' as size arguments, and various
iovec check differences that Vasily Gorbik pointed out) that I ended up
with this more limited version that fixed the worst of the issues.

Initialize bridge_connector for both Rockchip and Exynos encoder sides.
Then, make DRM_BRIDGE_ATTACH_NO_CONNECTOR mandatory for Analogix bridge
side, as the private &drm_connector is no longer created.
The previous &drm_connector_funcs and &drm_connector_helper_funcs APIs
are replaced by the corresponding &drm_bridge_funcs APIs:
analogix_dp_atomic_check() -> analogix_dp_bridge_atomic_check()
analogix_dp_detect() -> analogix_dp_bridge_detect()
analogix_dp_get_modes() -> analogix_dp_bridge_get_modes()
analogix_dp_bridge_edid_read()
Additionally, the compatibilities of Analogix DP bridge based on whether
the next bridge is a 'panel'. If it is, OP_MODES and OP_DETECT are
supported; If not (the next bridge is a 'monitor' or a bridge chip),
OP_EDID and OP_DETECT are supported.
The devm_drm_bridge_add() is placed in analogix_dp_bind() instead of
analogix_dp_probe(), because the type of next bridge (the panel, monitor
or bridge chip) can only be determined after the probe process has fully
completed.

dma_buf_put() may drop the final file reference via fput(), which
can free the dma-buf. The new tracepoint invocation was added
after fput(), and DMA_BUF_TRACE() dereferences dmabuf and takes
dmabuf->name_lock.
This leads to a use-after-free on the final put, visible for

Instead of using the pin descriptions, pin functions and register offsets
of the EyeQ5 directly, access those via a pointer to a newly introduced
struct eq5p_match_data.
This structure contains, in addition to the pin descriptions and pin
functions, an array of pin banks. Each bank holds the number of pins
and the register offsets.
All functions accessing a pin now use a pointer to a bank structure and
an offset inside that bank. The conversion from a pin number to a bank
and an offset is done in the new function eq5p_pin_to_bank_offset(),
which replace eq5p_pin_to_bank() and eq5p_pin_to_offset().
All the data related to the EyeQ5 is declared with the eq5p_eyeq5_
prefix to distinguish it from the common code.
During the probe, we use the parent OF node to get the match data.
We cannot directly use an OF node since pinctrl-eyeq5 is an auxiliary
device of clk-eyeq.

When a Bluetooth controller encounters a coredump, it triggers the
Subsystem Restart (SSR) mechanism. The controller first reports the
coredump data and, once the upload is complete, sends a hw_error
event. The host relies on this event to proceed with subsequent
recovery actions.
If the host has not finished processing the coredump data when the
hw_error event is received, it waits until either the processing is
complete or the 8-second timeout expires before handling the event.
The current implementation clears QCA_MEMDUMP_COLLECTION using
clear_bit(), which does not wake up waiters sleeping in
wait_on_bit_timeout(). As a result, the waiting thread may remain
blocked until the timeout expires even if the coredump collection
has already completed.
Fix this by clearing QCA_MEMDUMP_COLLECTION with
clear_and_wake_up_bit(), which also wakes up the waiting thread and
allows the hw_error handling to proceed immediately.
Test case:
- Trigger a controller coredump using:
hcitool cmd 0x3f 0c 26
- Tested on QCA6390.
- Capture HCI logs using btmon.
- Verify that the delay between receiving the hw_error event and
initiating the power-off sequence is reduced compared to the
timeout-based behavior.

Some MT6639 Bluetooth USB interfaces (e.g. IMC Networks 13d3:3588 on
ASUS ROG STRIX X870E-E and ProArt X870E-Creator boards) expose only a
single alternate setting (alt 0) on the ISO interface. The driver
unconditionally requests alt setting 1, which fails with EINVAL on
these devices, causing a ~20 second initialization delay and no LE
audio support.
Check the number of available alternate settings before selecting one.
If only alt 0 exists, use it; otherwise request alt 1 as before.

The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses
hardware variant 0x6639 for its Bluetooth subsystem. Without this patch,
the chip fails with "Unsupported hardware variant (00006639)" or hangs
during firmware download.
Three changes are needed to support MT6639:
1. CHIPID workaround: On some boards the BT USB MMIO register reads
0x0000 for dev_id, causing the driver to skip the 0x6639 init path.
Force dev_id to 0x6639 only when the USB VID/PID matches a known
MT6639 device, avoiding misdetection if a future chip also reads
zero. This follows the WiFi-side pattern that uses PCI device IDs
to scope the same workaround.
2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of
"1_1" used by MT7925 and other variants. The firmware path is
mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927
directory to match the WiFi firmware convention. The filename will
likely change to use MT7927 once MediaTek submits a dedicated
Linux firmware binary.
3. Section filtering: The MT6639 firmware binary contains 9 sections, but
only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related.
Sending the remaining WiFi/other sections causes an irreversible BT
subsystem hang requiring a full power cycle. This matches the Windows
driver behavior observed via USB captures.
Also add 0x6639 to the reset register (CONNV3) and firmware setup switch
cases alongside the existing 0x7925 handling.

When hci_register_dev() fails in hci_uart_register_dev()
HCI_UART_PROTO_INIT is not cleared before calling hu->proto->close(hu)
and setting hu->hdev to NULL. This means incoming UART data will reach
the protocol-specific recv handler in hci_uart_tty_receive() after
resources are freed.
Clear HCI_UART_PROTO_INIT with a write lock before calling
hu->proto->close() and setting hu->hdev to NULL. The write lock ensures
all active readers have completed and no new reader can enter the
protocol recv path before resources are freed.
This allows the protocol-specific recv functions to remove the
"HCI_UART_REGISTERED" guard without risking a null pointer dereference
if hci_register_dev() fails.

On platforms using an M.2 slot with both UART and USB support, bt_en is

should be disabled. The current platforms are Lemans-EVK and Monaco-EVK.
Add QCA_WCN7850 to the existing condition so that power_ctrl_enabled is
cleared when bt_en is not software-controlled (or absent), aligning its
behavior with WCN6750 and WCN6855

Separate the rx and tx enablement/disablement into different
functions so that it is easier to interact with them independently
later.
Although this patch changes receive and transmit paths, the actual
behavior of the teaming driver should remain unchanged, since there
is no option introduced yet to change rx or tx enablement
independently. Those options will be added in follow-up patches.

Add no functional changes, but rename enablement functions, variables
etc. that are used in teaming driver transmit decisions.
Since rx and tx enablement are still coupled, some of the variables
renamed in this patch are still used for the rx path, but that will
change in a follow-up patch.
