Merge ACPI bus type code updates, ACPI sysfs code updates related to exposing table data, updates of ACPI data-only table parsers and assorted driver changes related to ACPI support for 7.3-rc1: - Eliminate struct acpi_driver whose users have all been converted to bind to platform devices or auxiliary devices and set the "no power management" flag for all struct acpi_device objects (Rafael Wysocki) - Update kerneldoc comments of two structures in the ACPI bus type code to use correct struct member names to avoid warnings (Randy Dunlap) - Avoid complaints regarding missing _OSC features on platforms where OSC_CAPABILITIES_MASK_ERROR is set in _OSC error bits even though all of the requested features are actually acknowledged (Rafael Wysocki) - Use correct region struct for BERT region size check and properly map BERT and CCEL data to their ACPI tables (Thomas Renninger) - Clean up the list of included header files in the NHLT table parser and validate the table and record lengths in the FPDT parser (Andy Shevchenko and Pengpeng Hou) - Stop using acpi_device_name() in the PNP core, stop setting acpi_device_name/class() in the Xen variant of the ACPI PAD (Processor Aggregator Device) driver, and make the Loongarch laptop driver stop setting acpi_device_class() (Rafael Wysocki) * acpi-bus: ACPI: bus: Avoid confusing complaints regarding missing _OSC features ACPI: bus: Use correct struct member names ACPI: scan: Set power.no_pm for all struct acpi_device objects ACPI: bus: Eliminate struct acpi_driver * acpi-sysfs: ACPI: sysfs: Properly map BERT and CCEL data to their ACPI tables ACPI: Use correct region struct for BERT region size check * acpi-tables: ACPI: NHLT: Remove always included kconfig.h ACPI: FPDT: validate table and record lengths * acpi-driver: PNP: ACPI: Stop using acpi_device_name() ACPI: PAD: xen: Stop setting acpi_device_name/class() platform/loongarch: laptop: Stop setting acpi_device_class()
Linux kernel ============ The Linux kernel is the core of any Linux operating system. It manages hardware, system resources, and provides the fundamental services for all other software. Quick Start ----------- * Report a bug: See Documentation/admin-guide/reporting-issues.rst * Get the latest kernel: https://kernel.org * Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst * Join the community: https://lore.kernel.org/ Essential Documentation ----------------------- All users should be familiar with: * Building requirements: Documentation/process/changes.rst * Code of Conduct: Documentation/process/code-of-conduct.rst * License: See COPYING Documentation can be built with make htmldocs or viewed online at: https://www.kernel.org/doc/html/latest/ Who Are You? ============ Find your role below: * New Kernel Developer - Getting started with kernel development * Academic Researcher - Studying kernel internals and architecture * Security Expert - Hardening and vulnerability analysis * Backport/Maintenance Engineer - Maintaining stable kernels * System Administrator - Configuring and troubleshooting * Maintainer - Leading subsystems and reviewing patches * Hardware Vendor - Writing drivers for new hardware * Distribution Maintainer - Packaging kernels for distros * AI Coding Assistant - LLMs and AI-powered development tools For Specific Users ================== New Kernel Developer -------------------- Welcome!
