7117fc3d1fda061cf83b2f580d2f49596d49c3db - spi: Add trace event support for GENI SE registers dump

Wed, 29 Jul 2026 22:41:32 +0200

spi: Add trace event support for GENI SE registers dumpPraveen Talari says:The GENI framework is used by multiple drivers including UART, I2C, andSPI. When hardware-related failures occur, each driver typically relieson local logging, which often lacks sufficient information to determinethe exact controller state.This series introduces a common tracing mechanism for GENI Serial Enginedebug registers and demonstrates its use in the SPI driver.Patch 1 adds a new tracepoint that captures an extensive set of GENI SEregisters, including command state, interrupt status, FIFO state, DMAconfiguration, and clock-related information.Patch 2 hooks the tracepoint into SPI error paths so that registersnapshots are automatically generated when timeouts or transfer-relatedfailures occur.Usage examples:Enable all I2C traces:echo 1 > /sys/kernel/tracing/events/qcom_geni_se/enablecat /sys/kernel/debug/tracing/trace_pipeExample trace output:114.291299: geni_se_regs: 888000.spi: m_cmd0=0x18000000 m_irq_status=0x00000080 s_cmd0=0x00000000 s_irq_status=0x08000000geni_status=0x00000000 geni_ios=0x00000000 m_cmd_ctrl=0x00000000m_cmd_err=0x00000000 m_fw_err=0x00000000 tx_fifo_sts=0x00000000rx_fifo_sts=0x00000000 tx_watermark=0x00000000 rx_watermark=0x0000000drx_watermark_rfr=0x0000000e m_gp_length=0x00000004 s_gp_length=0x00000000dma_tx_irq=0x00000000 dma_rx_irq=0x00000000 dma_tx_irq_en=0x0000000fdma_rx_irq_en=0x0000001f dma_rx_len=0x00001400 dma_rx_len_in=0x00001400dma_tx_len=0x00001400 dma_tx_len_in=0x00001400 dma_tx_ptr_l=0xffffc000dma_tx_ptr_h=0x00000000 dma_rx_ptr_l=0xffffa000 dma_rx_ptr_h=0x00000000dma_tx_attr=0x00000001 dma_tx_max_burst=0x00000002 dma_rx_attr=0x00000000dma_rx_max_burst=0x00000002 dma_if_en=0x00000009 dma_if_en_ro=0x00000001dma_general_cfg=0x0000000f dma_qsb_trans_cfg=0x00000000 dma_dbg=0x00000000m_irq_en=0x7fc0007f s_irq_en=0x03003e3e gsi_event_en=0x00000000se_irq_en=0x0000000f ser_m_clk_cfg=0x000000a1 ser_s_clk_cfg=0x00000000general_cfg=0x00000048 output_ctrl=0x0000007f clk_ctrl_ro=0x00000001fifo_if_dis=0x00000000 fw_multilock_msa=0x00000000 clk_sel=0x00000005Link: https://patch.msgid.link/20260729-add-tracepoints-for-se-reg-dump-v4-0-08bbd63b0ed2@oss.qualcomm.com List of files: /linux/rust/Makefile

It includes a probe for the bug in case 'bindgen' happens to be patched, and tests In parallel, Nathan updated the instructions for the kernel.org LLVM+Rust toolchains so that the latest version of 'bindgen' is installed, which should avoid some of these situations - Support testing 'rust_is_available.sh' with 'bash' as '/bin/sh' - Fix an objtool warning by adding one more 'noreturn' function for Rust 1.99.0 (expected 2026-10-01) - Fix build error in the 'rusttest' target due to ambiguity when the 'rustc-dev' component is installed, which was uncovered by the work to support Rust's GCC backend ('rustc_codegen_gcc') - Fix future Clang warnings in the upcoming powerpc support due to macro redefinitions in the UAPI helper header by including the arch-aware 'ioctl.h' header 'kernel' crate: - Rework module ownership support: - Move the module-related types into a new 'module' module and make the 'THIS_MODULE' pointer a constant of 'ModuleMetadata' so that modules can provide the pointer in const contexts, and add a 'this_module' 'const fn' to retrieve it This was enabled by upstream Rust's work on the 'const_mut_refs' and 'const_refs_to_static' features which were stabilized back in Rust 1.83.0 - Teach '#[vtable]' to associate implementations with their owning module, defaulting to the local one, including fallbacks for doctests, uses within the 'kernel' crate (like upcoming KUnit '#[test]'s for DRM) and 'rusttest' - Set 'fops.owner' from the module pointer for DRM and miscdevice - Migrate Rust Binder and configfs away from the old 'THIS_MODULE' 'static' and finally remove it from the 'module!' macro - 'num' module: - Add the new 'casts' module for lossless integer conversions Rust's 'core' library's 'From' implementations do not cover conversions that are not portable or future-proof. However, the kernel supports a narrower set of architectures, which makes it helpful to provide more infallible conversions, instead of having developers use 'as' casts, which carry the risk of silently losing data This goes along with previous work we did to avoid casts in Rust kernel code since they are more powerful than needed Thus, provide safe 'const' conversion functions (e.g. 'usize_as_u64' and 'u64_into_u8'), as well as the 'FromSafeCast' and 'IntoSafeCast' extension traits that provide conversions that are known to be lossless in the kernel, and an 'arch' submodule defining conversions that are known to be lossless on particular architectures (e.g. 64-bit platforms). For instance: // Conversion in const context. const USIZED_CONST: usize = u8_as_usize(255u8); // Non-const conversions. let a = u64::from_safe_cast(4096usize); let b: u64 = 4096usize.into_safe_cast(); - Add 'Bounded::shr_exact' method in the vein of 'try_shrink' which shifts a bounded right only if it loses no set bits - Fix unsoundness issue in the 'Bounded::shr' method by rejecting, at compile-time, shifts of at least the type's bit width - 'fmt' module: - Route '{:p}' raw pointer formatting through the kernel's hashed '%p' format to prevent address leaks, including support for width and padding. Include tests for both 'no_hash_pointers' case and the default (hashed) one - Fix the '{:p}' forwarding implementation, which could print the address of a temporary stack variable - 'time' module: - Make 'Delta' generic over its time unit, with a default unit of nanoseconds ('Nsec'), preserving the existing behavior. Then, add a 'Jiffy' time unit - Add the 'Delta::as_millis_ceil()' method - Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could yield a result one microsecond too small - 'sync' module: - Implement 'ForeignOwnable' for 'ARef', allowing C code to own an 'ARef' - Add a safe abstraction for 'rcu_barrier()' - 'error' module: add all of the remaining error codes, except the deprecated compatibility aliases - 'bug' module: - Fix build error on UML in 'warn_on!' for callers from within the 'kernel' crate - Fix future 'dead_code' warning on arm and loongarch64 and under 'CONFIG_BUG=n' in 'warn_on!', which would trigger with the upcoming SRCU abstractions - Fix future build error in 'rusttest' on cross-compilation cases, which would trigger when 'warn_on!' has callers inside the 'kernel' crate - 'bitfield' module: fix build error for the upcoming support for Rust's GCC backend ('rustc_codegen_gcc') by always inlining a couple conversions used in tests 'pin-init' crate: - User-visible changes: - Merge the '__pinned_init' and '__init' methods and make 'Init' a marker trait - Introduce public APIs 'raw_init' and 'raw_try_init' to prevent users from needing to invoke the internal '__pinned_init' and '__init' methods - Emit errors for duplicate '#[pin]' attributes - Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation - Other changes: - Fix unwind safety issues - Clean up lint 'allow' and 'expect's - Overhaul '#[cfg]' handling to pave the way for tuple structs and self-referential structs - Mark many functions as '#[inline]' for better codegen with '-C opt-level=s' ('CC_OPTIMIZE_FOR_SIZE') 'MAINTAINERS': - Update 'MODULE SUPPORT' to cover the new 'module' module And some other fixes, cleanups and improvements"* tag 'rust-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux: (54 commits) rust: add functions and traits for lossless integer conversions rust: kernel: add `LocalModule` fallback for `#[vtable]` `impl`s rust: fmt: route {:p} through HashedPtr to prevent address leaks rust: fmt: fix {:p} printing stack addresses rust: module: update MAINTAINERS to cover module.rs rust: macros: remove `THIS_MODULE` static from `module!` rust_binder: use `LocalModule` for `THIS_MODULE` rust: configfs: use `LocalModule` for `THIS_MODULE` rust: miscdevice: set fops.owner from driver module pointer rust: drm: set fops.owner from driver module pointer rust: macros: auto-insert OwnerModule in #[vtable] rust: doctest: add LocalModule fallback for #[vtable] ThisModule rust: module: add `THIS_MODULE` const to `ModuleMetadata` trait rust: module: move module types into `module.rs` rust: num: add Bounded::shr_exact rust: num: reject Bounded::shr overshifts at build time rust: num: use const_assert! in Bounded rust: uapi: replace direct asm-generic/ioctl.h include with linux/ioctl.h rust: time: add Delta::as_millis_ceil() rust: time: add jiffies time unit for Delta ...

73b741adb264967093ef4eb59905618a7e0d0de0 - rust: Add PowerPC support

Wed, 08 Jul 2026 10:24:53 +0200

rust: Add PowerPC supportFor now only Big Endian 32-bit PowerPC is supported, as that is the onlyhardware I have. This has been tested on the Nintendo Wii so far, but Iplan on also using it on the GameCube, Wii U and Apple G4.These changes aren’t the only ones required to get the kernel to compileand link on PowerPC, libcore will also have to be changed to not useinteger division to format u64, u128 and core::time::Duration, otherwise__udivdi3() and __umoddi3() will have to be added. I have tested thischange by replacing the three implementations with unimplemented!() andit linked just fine.Signed-off-by: Link Mauve Link: https://github.com/Rust-for-Linux/linux/issues/105Link: https://github.com/linuxppc/issues/issues/451Acked-by: Gary Guo Link: https://github.com/rust-lang/compiler-team/issues/986Signed-off-by: Mukesh Kumar Chaurasiya (IBM) Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20260708082454.1254320-7-mkchauras@gmail.com List of files: /linux/rust/Makefile
