- 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.
* Add combined on-CPU and off-CPU profiler script
- Implemented a new profiling tool that captures both on-CPU and off-CPU activity for a specified process.
- The script runs 'oncputime' and 'offcputime' tools simultaneously and combines their results into a unified flamegraph.
- Added functionality to discover threads and profile them individually if the application is multi-threaded.
- Included error handling for tool execution and output processing.
- Created methods for generating flamegraph data and SVG visualizations.
- Added command-line argument parsing for user-defined profiling parameters.
- Implemented detailed analysis reports for both individual threads and overall profiling results.
