- Updated README.zh.md for GPU kernel driver to improve clarity and formatting.
- Added nvidia_driver.bt script for monitoring NVIDIA proprietary GPU driver activity using kernel probes.
- Revised README.md for NPU kernel driver to enhance explanations and correct minor grammatical issues.
- 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.
- 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 a comprehensive README.md detailing the use of eBPF for monitoring GPU activity through kernel tracepoints.
- Added bpftrace scripts for monitoring AMD GPU operations, including buffer object creation, command submission, and interrupts.
- Created a bpftrace script for tracking DRM GPU scheduler activity across all modern GPU drivers.
- Developed a bpftrace script to monitor display vertical blanking events for frame timing analysis.
- Implemented a bpftrace script for Intel i915 GPU activity, focusing on GEM object management, memory operations, and page faults.
