Nvidia Patch
nvidia-patch 是一个针对 Nvidia 驱动程序的二进制修改工具，旨在移除消费级硬件上的人为制造商限制。它主要作为并发视频编码会话的解锁器，并激活高性能帧缓冲区屏幕捕获功能。
该项目包含一个 GPU 驱动程序二进制补丁程序，能够在隔离环境（如容器和 Flatpak 运行时）中修改驱动程序库。它利用动态链接器操作将这些补丁应用于位于只读文件系统上的二进制文件。
该工具提供了状态保留的二进制备份机制，以允许驱动程序补丁回滚。它还包括验证工具，通过执行并发编码任务来确认会话限制已成功移除。
Features
- NVENC Session Unlocking - Removing the manufacturer limit on simultaneous video encoding sessions to allow more concurrent streams on consumer GPUs.
- High-Performance Video Capture - Unlocks high-performance frame buffer capture capabilities on consumer-grade hardware.
- Encoding Limit Removal - Eliminates the maximum number of simultaneous video encoding sessions on consumer hardware.
- Linker Redirection Tools - Utilizes dynamic linker interception to apply binary patches on read-only filesystems.
- Compiled Driver Injection - Injects pre-compiled modified driver libraries into container and Flatpak sandbox runtimes.
- Driver Binary Patching - Provides capabilities to modify compiled driver binaries to remove artificial hardware limitations.
- Frame Buffer Captures - Activates raw pixel data capture from frame buffers on restricted consumer hardware.
- Flatpak Runtime Customization - Modifies driver binaries within sandbox runtimes to enable high-performance encoding and capture.
- Runtime Driver Patching - Modifies driver binaries within Flatpak sandboxes to enable enhanced encoding and capture features.
- Container Driver Modification - Allows applying driver patches inside containers using dynamic linker manipulation.
- Encoding Session Verifications - Includes tooling to validate the successful removal of NVENC session limits via concurrent encoding tasks.
- Containerized Driver Patching - Enables applying driver patches inside containers to bypass read-only filesystem mounts.
- Patch Success Verifications - Executes concurrent encoding tasks to confirm that session limits have been removed.
- Driver Backups - Saves original driver library snapshots to enable atomic restoration of factory settings.
- Plex Infrastructure - Unlocks session limits on consumer-grade Nvidia GPUs.
