2026-03-23rust: dma: add zeroed constructor to `Coherent`Gary Guo
These constructors create a coherent container of a single object instead of slice. They are named `zeroed` and `zeroed_with_attrs` to emphasis that they are created initialized zeroed. It is intended that there'll be new constructors that take `PinInit` instead of zeroing.

Introduce a core helper function for VFIO_MIG_GET_PRECOPY_INFO and adapt all drivers to use it. It centralizes the common code and ensures that output flags are cleared on entry, in case user opts in to VFIO_DEVICE_FEATURE_MIG_PRECOPY_INFOv2.

2026-03-19sample/tsm-mr: Use SHA-2 library APIsEric Biggers
Given that tsm_mr_sample has a particular set of algorithms that it wants, just use the library APIs for those algorithms rather than crypto_shash. This is more straightforward and more efficient. This also fixes a bug where this module failed to build if it was enabled without CRYPTO_HASH happening to be set elsewhere in the kconfig. (With the concurrent change to make TSM_MEASUREMENTS stop selecting CRYPTO, this existing build error would have become easier to encounter, as well.) Also, even if it built, crypto_alloc_shash() could fail at runtime due to the needed algorithms not being available. The library functions simply use direct linking. So if it builds, which it will due to the kconfig options being selected, they are available.

2026-03-07rust: dma: use pointer projection infra for `dma_{read,write}` macroGary Guo
Current `dma_read!`, `dma_write!` macros also use a custom `addr_of!()`-based implementation for projecting pointers, which has soundness issue as it relies on absence of `Deref` implementation on types. It also has a soundness issue where it does not protect against unaligned fields (when `#[repr(packed)]` is used) so it can generate misaligned accesses. This commit migrates them to use the general pointer projection infrastructure, which handles these cases correctly. As part of migration, the macro is updated to have an improved surface syntax. The current macro have dma_read!(a.b.c[d].e.f) to mean `a.b.c` is a DMA coherent allocation and it should project into it with `[d].e.f` and do a read, which is confusing as it makes the indexing operator integral to the macro (so it will break if you have an array of `CoherentAllocation`, for example). This also is problematic as we would like to generalize `CoherentAllocation` from just slices to arbitrary types. Make the macro expects `dma_read!(path.to.dma, .path.inside.dma)` as the canonical syntax. The index operator is no longer special and is just one type of projection (in additional to field projection). Similarly, make `dma_write!(path.to.dma, .path.inside.dma, value)` become the canonical syntax for writing. Another issue of the current macro is that it is always fallible. This makes sense with existing design of `CoherentAllocation`, but once we support fixed size arrays with `CoherentAllocation`, it is desirable to have the ability to perform infallible indexing as well, e.g. doing a `[0]` index of `[Foo; 2]` is okay and can be checked at build-time, so forcing falliblity is non-ideal. To capture this, the macro is changed to use `[idx]` as infallible projection and `[idx]?` as fallible index projection (those syntax are part of the general projection infra). A benefit of this is that while individual indexing operation may fail, the overall read/write operation is not fallible.

The previous Io<SIZE> type combined both the generic I/O access helpers and MMIO implementation details in a single struct. This coupling prevented reusing the I/O helpers for other backends, such as PCI configuration space. Establish a clean separation between the I/O interface and concrete backends by separating generic I/O helpers from MMIO implementation. Introduce a new trait hierarchy to handle different access capabilities: - IoCapable<T>: A marker trait indicating that a backend supports I/O operations of a certain type (u8, u16, u32, or u64). - Io trait: Defines fallible (try_read8, try_write8, etc.) and infallibile (read8, write8, etc.) I/O methods with runtime bounds checking and compile-time bounds checking. - IoKnownSize trait: The marker trait for types support infallible I/O methods. Move the MMIO-specific logic into a dedicated Mmio<SIZE> type that implements the Io traits. Rename IoRaw to MmioRaw and update consumers to use the new types.

2025-12-31samples/ftrace: Adjust LoongArch register restore order in direct callsChenghao Duan
Ensure that in the ftrace direct call logic, the CPU register state (with ra = parent return address) is restored to the correct state after the execution of the custom trampoline function and before returning to the traced function. Additionally, guarantee the correctness of the jump logic for jr t0 (traced function address).
