## Synopsis

```
# bash ./patch.sh -h

SYNOPSIS
       patch.sh [-s] [-r|-h|-c VERSION|-l]

DESCRIPTION
       The patch for Nvidia drivers to remove NVENC session limit

       -s             Silent mode (No output)
       -r             Rollback to original (Restore lib from backup)
       -h             Print this help message
       -c VERSION     Check if version VERSION supported by this patch.
                      Returns true exit code (0) if version is supported.
       -l             List supported driver versions

```

## Step-by-Step guide

Examples are provided for driver version 430.50. All commands executed as root.

### Download and install driver

Skip this step if you already have installed driver with version supported by this patch (from distro packages, for example).

Make sure you have kernel headers and compiler installed before running Nvidia driver installer. Kernel headers and compiler are required to build nvidia kernel module. Recommended way to do this is to install `dkms` package, if it is available in your distro. This way `dkms` package will pull all required dependencies to allow building kernel modules and kernel module builds will be automated in a reliable fashion.

```bash
mkdir /opt/nvidia && cd /opt/nvidia
wget https://international.download.nvidia.com/XFree86/Linux-x86_64/430.50/NVIDIA-Linux-x86_64-430.50.run
chmod +x ./NVIDIA-Linux-x86_64-430.50.run
./NVIDIA-Linux-x86_64-430.50.run
```

### Check driver

```bash
nvidia-smi
```

Output should show no errors and details about your driver and GPU.

### Patch driver

This patch performs backup of original file prior to making changes.

```bash
bash ./patch.sh
```

You're all set!

## Rollback

If something got broken you may restore patched driver from backup:

```bash
bash ./patch.sh -r
```

## Docker support

It is possible to use this patch with nvidia-docker containers, even if host machine hasn't patched drivers. See `Dockerfile` for example.

Essentially all you need to do during build is:

* `COPY` the `patch.sh` and `docker-entrypoint.sh` files into your container.
* Make sure `docker-entrypoint.sh` is invoked on container start.

`docker-entrypoint.sh` script does on-the-fly patching by means of manipulating dynamic linker to workaround read-only mount of Nvidia runtime. Finally it passes original docker command to shell, like if entrypoint was not restricted by `ENTRYPOINT` directive. So `docker run --runtime=nvidia -it mycontainer echo 123` will print `123`. Also it can be just invoked from your entrypoint script, if you have any.

## Benchmarks

If you experience `CreateBitstreamBuffer failed: out of memory (10)`, then you have to lower buffers number used for every encoding session. If you are using `ffmpeg`, see option `-surfaces` ("Number of concurrent surfaces") and try value near `-surfaces 8`.

linux: readme: add notes about dkms 2019-07-20 20:36:41 +00:00			Make sure you have kernel headers and compiler installed before running Nvidia driver installer. Kernel headers and compiler are required to build nvidia kernel module. Recommended way to do this is to install `dkms` package, if it is available in your distro. This way `dkms` package will pull all required dependencies to allow building kernel modules and kernel module builds will be automated in a reliable fashion.

docs: docker support 2019-07-11 00:11:15 +00:00			`## Docker support`

			It is possible to use this patch with nvidia-docker containers, even if host machine hasn't patched drivers. See `Dockerfile` for example.

			`Essentially all you need to do during build is:`

			* `COPY` the `patch.sh` and `docker-entrypoint.sh` files into your container.
			* Make sure `docker-entrypoint.sh` is invoked on container start.

			`docker-entrypoint.sh` script does on-the-fly patching by means of manipulating dynamic linker to workaround read-only mount of Nvidia runtime. Finally it passes original docker command to shell, like if entrypoint was not restricted by `ENTRYPOINT` directive. So `docker run --runtime=nvidia -it mycontainer echo 123` will print `123`. Also it can be just invoked from your entrypoint script, if you have any.

If you are using `ffmpeg`, see option `-surfaces` ("Number of concurrent surfaces") and try value near `-surfaces 8`.
