- Introduced a comprehensive tutorial in README.md explaining how to fix broken HID devices using eBPF without kernel patches.
- Implemented a userspace program (hid-input-modifier.c) that creates a virtual HID mouse using the uhid interface and sends synthetic mouse events.
- Developed a BPF program (hid-input-modifier.bpf.c) that intercepts HID events and modifies mouse movement data, effectively doubling the X and Y movement.
- Created necessary header files (hid_bpf.h, hid_bpf_defs.h, hid_bpf_helpers.h) to define structures and helper functions for the BPF program.
- Added functionality to find and manage the virtual HID device, ensuring seamless integration with the BPF program.
- Created SUMMARY.md.template and SUMMARY.zh.md.template for eBPF tutorial.
- Updated generate_toc.py to generate table of contents for English and Chinese versions.
- Added configuration files for new eBPF examples, categorizing them by level and type.
- Updated SUMMARY.md and SUMMARY.zh.md to reflect new lessons and reorganized sections.
- Introduced new features related to GPU and tracing in the tutorial.
- Removed unnecessary print statements for arena sum and number of elements in the test_arena_list_add_del function.
- Simplified output to focus on essential test results, improving clarity and conciseness of the test logs.
- Introduced BPF workqueues to enable asynchronous work from BPF programs, allowing deferred processing, non-blocking operations, and sleepable contexts for long-running tasks.
- Added README.md to document the BPF workqueues, including use cases, technical architecture, and code examples.
- Created bpf_experimental.h header file to define necessary BPF workqueue functions and structures.
- Implemented a simple BPF workqueue example (wq_simple) demonstrating the initialization, scheduling, and execution of work in a separate context.
- Developed a userspace test (wq_simple.c) to verify the functionality of the BPF workqueue by triggering a syscall and checking the execution results.
