BayLibre at the GNU Tools Cauldron 2025

Over 140 attendees interested in the GNU Compiler Collection (GCC), GLIBC, Binutils, GNU Debugger (GDB), and related GNU Toolchain packages gathered for three days in Porto at the end of September 2025, including five toolchain developers from BayLibre. With sixty talks and BoFs in up to four parallel sessions, it was the most packed GNU Tools Cauldron so far!

The attending BayLibrers enjoyed the conference a lot, and would like to thank the Department of Informatics Engineering (DEI) of the Faculty of Engineering (FEUP) of the University of Porto for hosting the conference, the conference organizers, all the sponsors — including BayLibre as one of the GNU Tools Cauldron sponsors.

Comparative Analysis of GCC Codegen for AArch64 and RISC-V

In the talk, Paul-Antoine Arras of BayLibre showed the results of exploring possible improvements in GCC code generation for RISC-V. This was done by collecting dynamic instruction counts from selected SPEC CPU 2017 benchmarks and comparing the results with AArch64.

Findings revealed that prominent compiler weaknesses include:

  • missing instruction patterns
  • extra move instructions
  • unused load offsets
  • functionally dead code

Additionally, vectorising library functions, like memset and mathematical operations, are crucial for maximising RISC-V efficiency.

Parallel Computing, Offloading, OpenMP and OpenACC

In the talk, Thomas Schwinge and Tobias Burnus of BayLibre presented the progress, current status, future work, and ideas for features important for (not only) scientific computation.

Highlights and Status Updates:

  • AMD GPUs: One of the highlights in GCC 15 is generic architecture support (finally added by AMD to their runtime in April 2025, and already supported in GCC 15). For GCC 16, to be released in spring 2026, support of AMD’s MI300 accelerators is planned, in addition to the usual bug fixes, and performance improvements.
  • Nvidia GPUs: The global constructor support added in GCC 15 means not only better support for C++, but also enables device-side Fortran screen output.
  • OpenACC support keeps getting extended.
  • OpenMP 5.x and 6.0: Several features have already been released as part of GCC 15, such as interop, permitting interoperability with NVIDIA CUDA and AMD HIP libraries (for example, for fast Fourier transform (FFT) or linear algebra routines), loop transformations, dynamic context selectors. Development of additional features is ongoing for GCC 16.
  • For OpenMP, full coverage of 5.2 is in sight, several omissions are expected to land soon. Other features are still in early stages of development, such as OMPT (tools) support and, in particular, OMPD (debugging) support.
  • Thomas did a live demo of Arijit Kumar Das’ Google Summer of Code (GSoC) project: “Implementation of a simple in-memory file system for running offloading tests on NVIDIA GPUs”, which Thomas had been the mentor for, with help by Tobias.
  • Future Ideas (BoF discussion): Amongst other miscellaneous topics, the BoF discussion included a proposal for adding to GCC a low-overhead GPU kernel language, to enable programming at an abstraction level similar to NVIDIA CUDA or AMD HIP language extensions. This also serves as foundational work for support of related new functionality that’s currently in process of standardization in the upcoming OpenMP 6.x and 7.0 specifications.

Toolchain and Linux kernel

As part of this BoF, Thomas Schwinge of BayLibre gave a short report of his Kernel Recipes 2025 conference participation the week before. In his KR2025 presentation (“Recipe for baking a GCC: Ingredients and community of the GNU Compiler Collection, 2025”), he had primarily covered history and structure of the GNU Compiler Collection (GCC) project and community, but after that one, a number of related technical discussions also took place, including on Rust programming language support in GCC, and GCC’s support for BPF (eBPF) code generation. In the Cauldron BoF, some of these topics then got discussed in further detail.

For the Cauldron BoF audience, he also repeated the live demo of Piyush Raj’s Google Summer of Code (GSoC) project to develop “tooling for running BPF GCC tests on a live kernel”,which he had helped co-mentor, in collaboration with José E. Marchesi and David Faust of Oracle’s Toolchain/Compilers team.

Quantifying Abstraction Costs in GCC
GCC BOF: Reviewing refactoring goals and acceptable abstractions

Software benefits from occasional cleanup and refactoring. Not only should the generated code be fast, but building the compiler and compiling user programs should also be fast and avoid excessive memory usage.

Therefore, Waffl3x of BayLibre explored the topic of measuring the GCC performance. This measurement is crucial for detecting regressions and for checking that refactoring work has no unintended effects on compilation speed or memory consumption.

In the BoF part, ways to improve the internal representation in GCC were discussed.

BayLibre contributions to Linux v6.17

/in , , /by

Linus released Linux 6.17 on September 28, 2025. BayLibre contributed to this release across multiple subsystems, focusing on IIO drivers, PWM infrastructure, SPI offload support, and platform improvements. BayLibre was once again among the top 20 contributing companies by number of changesets, while David Lechner ranked in the top 10 individual contributors by number of changesets.

IIO (Industrial I/O)

AD7606 Calibration and Power Management

Angelo Dureghello implemented comprehensive calibration support for the AD7606 family of ADCs. He added gain calibration using resistor values configured in Devicetree, specifically for external RFilter calibration as documented in the ad7606c-16 datasheet. The implementation supports offset and phase calibration for devices with software mode capability: ad7606b, ad7606c-16, and ad7606c-18.

Angelo added a new channel extension IIO_CHAN_INFO_CONVERSIONDELAY and the corresponding conversiondelay sysfs attriubte suffix. For the AD7606, this is used to calibrate the phase delay of the ADC. This attribute is more general to allow for other channel delay use cases in other chips as well. He also implemented power supply support by enabling the VDRIVE power supply and adding optional VREFIN reference voltage support for proper ADC operation.

The ad7606 driver received validation improvements to exit cleanly when invalid Devicetree schema properties are detected, and the channel scaling structure was renamed from chan_scale to the more generic chan_info to better reflect its broader usage.

DAC Infrastructure

Angelo optimized the adi-axi-dac driver by implementing a unified bus free check function, reducing code duplication and ensuring consistent error handling with timeout detection.

Sigma-Delta ADC Infrastructure and SPI Offload

David Lechner implemented SPI offload support for the ad_sigma_delta module, enabling high-performance buffered reads using SPI controller offload capabilities instead of RDY interrupt triggers. Drivers using this module can opt into SPI offload support through the supports_spi_offload flag, allowing gradual enablement for a number of ADCs that use this shared module.

He added the ADI Util Sigma-Delta SPI FPGA IP driver and corresponding Devicetree bindings. This IP bloc separates the data ready signal from SPI data on a shared pin, allowing it to trigger the SPI offload at the appropriate time.

David fixed buffer management issues in ad_sigma_delta by changing from postdisable to predisable callbacks, ensuring proper state handling when update_scan_mode operations fail.

ADC Driver Fixes and Improvements

David implemented fixes across multiple ADC drivers. In the AD7173 family, he corrected output data rate register initialization for the AD7177 chip, which has different reset values than other variants, and fixed channel lookup in system calibration functions. The AD7380 driver received a fix for missing max_conversion_rate_hz on the adaq4381-4 variant.

For the AD4000 family, David removed unnecessary usage of shift_right() functionality. He also fixed several endianness and buffer safety issues: corrected buffered reads on big-endian systems in the isl29501 proximity sensor, fixed uninitialized scan data in the sca3300 accelerometer, and addressed DMA-safe memory usage in temperature sensors.

IIO Framework and ABI Improvements

David corrected the IIO ABI documentation for I and Q channel modifiers, updating it to reflect actual usage patterns in drivers like admv1013, admv1014, and adrf6780. He removed unused attributes and fixed differential channel naming for RF/microwave applications.

Code Quality and Modernization

David conducted extensive code modernization across the IIO subsystem, replacing memset() calls with designated initializers (= { }) in over 20 drivers for cleaner, more readable code. He also made numerous data structures const where appropriate, improving memory safety and compiler optimization.

The ADA4250 amplifier driver received improvements including the use of devm_regulator_get_enable_read_voltage() for simplified power management, better error handling with dev_err_probe(), and fixes to chip ID validation logic.

SPI, GPIO, and Infrastructure Improvements

David enhanced GPIO handling by updating drivers to use gpiod_multi_set_value_cansleep() in the virtuser and mdio-mux-gpio drivers, reducing code verbosity.

David converted the Sitronix ST7586 display controller binding from text to YAML format and added datasheet links for improved documentation.

ARM64 Platform and Power Management

Guillaume La Roque cleaned up ARM64 Kconfig dependencies for TI K3 platforms by removing unnecessary selects from ARCH_K3 after improvements to the TI_MESSAGE_MANAGER and TI_SCI_PROTOCOL drivers. This allows these drivers to be built as modules and simplifies the dependency chain.

He also fixed power domain configuration by changing TI_SCI_PM_DOMAINS to select PM_GENERIC_DOMAINS instead of depending on it, ensuring proper power management functionality and preventing build issues since PM_GENERIC_DOMAINS is an implicit symbol that can only be enabled via select.

Clock Infrastructure

Jerome Brunet added new clk_hw helper functions clk_hw_get_dev() and clk_hw_get_of_node() to allow clock drivers to access device-related functionality such as devres and dev_ prints. He also added corresponding test coverage for these new helpers.

Jerome authored and committed modernization improvements to the Amlogic clock driver architecture. He removed clk_regmap tracking tables and moved initialization to the .init() operation of clk_regmap, reducing memory usage and simplifying maintenance. He cleaned up unused data in the S4 clock driver and removed unnecessary headers across Amlogic clock drivers.

Jerome authored the migration of the AXG-audio clock driver to use the auxiliary reset driver infrastructure, removing the local reset implementation and using the reset framework on the auxiliary bus.

PCI Endpoint Infrastructure

Jerome enhanced the PCI Virtual Non-Transparent Bridge (vNTB) endpoint function by adding configurable BAR assignment via configfs. This addresses platform-specific limitations on Renesas hardware where BAR_4 is a fixed 256B region better suited for doorbells than memory windows.

Driver Infrastructure and Auxiliary Bus

Jerome contributed to auxiliary bus infrastructure improvements, migrating the ti-sn65dsi86 bridge driver to use auxiliary devices and adding auxiliary device creation helpers for the Lenovo Yoga C630 platform. He also updated the Microchip PolarFire reset driver to use auxiliary device creation helpers, reducing boilerplate code.

ARM/OMAP Platform Support

As ARM/OMAP subsystem maintainer, Kevin Hilman committed platform improvements including BeagleBone Green Eco board support, AM335x RS-485 transceiver fixes, and various Devicetree cleanups.

Core Math Functions

Nicolas Pitre fixed division-by-zero behavior in mul_u64_u64_div_u64() by changing from compile-time undefined instruction generation to proper runtime division-by-zero exceptions, making the behavior consistent with other division operations.

Devicetree Bindings

Sukrut Bellary modernized TI clock Devicetree bindings by converting autoidle and fixed-factor-clock bindings from text to YAML format. He clarified that autoidle is a derivative feature of basic clocks rather than a standalone clock type, and updated examples to meet current standards.

PWM Infrastructure

Uwe Kleine-König authored the new pwmchip character device interface, enabling faster userspace access via ioctl instead of sysfs and reducing configuration time by more than 60% on STM32MP13 hardware. He systematically removed driver-local locking from eight PWM drivers (sun4i, fsl-ftm, microchip-core, lpc18xx-sct, twl-led, atmel, clps711x, sti) as the framework now provides adequate protection.

Uwe authored critical fixes for the MediaTek PWM driver, separating hardware enable and clock enable handling and fixing duty cycle and period setting issues. He enhanced PWM integration with other subsystems: improved the clock PWM driver to use non-sleeping PWMs when possible and return real duty cycles, added #pwm-cells = <3> support to the ADT7475 hwmon driver, and optimized PWM configuration in max8997 haptic and max77693 input drivers.

He also authored Devicetree updates adding PWM cell properties to LPC32xx and BCM958625 platforms, ARM STM32 nvmem-cells for constant MAC addresses, ACPI EINJ resource leak fixes, devfreq sun8i-a33-mbus simplifications, RTC calculation optimizations, and networking driver naming standardization.

As PWM subsystem maintainer, Uwe committed contributions from external developers including SiFive PWM fixes, LPC32xx binding conversions, and support for new hardware platforms.
