# Intel(R) Media Driver for VAAPI


## Introduction

The Intel(R) Media Driver for VAAPI is a new VA-API (Video Acceleration API)
user mode driver supporting hardware accelerated decoding, encoding, and
video post processing for GEN based graphics hardware.

## Building
For Ubuntu 16.04+

```
apt install autoconf libtool libdrm-dev xorg xorg-dev openbox libx11-dev libgl1-mesa-glx
```

Equivalents for other distributions should work.

1. Build and install [LibVA](https://github.com/intel/libva)
2. Build and install [GmmLib](https://github.com/intel/gmmlib) following [GmmLib compatibility](https://github.com/intel/media-driver/wiki/Compatibility-with-GmmLib)
3. Get media repo and format the workspace folder as below (suggest the workspace to be a dedicated one for media driver build):
    ```
    <workspace>
        |- media-driver
    ```
4. Create build_media new folder under your workspace
    ```
    $ mkdir <workspace>/build_media
    ```
    then the workspace looks like below
    ```
    <workspace>
        |- media-driver
        |- build_media
    ```
5.
    ```
    $ cd <workspace>/build_media
    ```
6.
    ```
    $ cmake ../media-driver
    ```
7.
    ```
    $ make -j"$(nproc)"
    ```

## Install

```
$ sudo make install
```
This will install the following files (e.g. on Ubuntu):
```
-- Installing: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
-- Installing: /etc/profile.d/intel-media.sh
-- Installing: /usr/lib/x86_64-linux-gnu/igfxcmrt64.so
```

For iHD_drv_video.so please export related LIBVA environment variables.
```
export LIBVA_DRIVERS_PATH=<path-contains-iHD_drv_video.so>
export LIBVA_DRIVER_NAME=iHD
```

## Components and Features

Media driver contains three components as below
- **Video decoding** calls hardware-based decoder([VDBox](https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol08-media_vdbox.pdf))  which provides fully-accelerated hardware video decoding to release the graphics engine for other operations.
- **Video encoding** supports two modes, one calls hardware-based encoder([VDEnc](https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol08-media_vdbox.pdf)/[Huc](https://01.org/linuxgraphics/downloads/firmware?langredirect=1)) to provide low power encoding, another one is hardware([PAK](https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol08-media_vdbox.pdf))+shader(media kernel+[VME](https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol04-configurations.pdf)) based encoding. User could choose the mode through VA-API.
- **Video processing** supports several popular features by hardware-based video processor([VEBox/SFC](https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol09-media_vebox.pdf)) and shader(media kernel) based solution together.

Media driver supports below two builds
- **Full Feature Build** is ***default*** driver build, which supports all feature by hardware accelerator and close source shaders(media kernel binaries). Most of OSVs(like RHEL/SUSE/fedora) are using this build.
- **Free Kernel Build**, enables fully open source shaders(media kernels) and hardware features but the features would be limited.

About Ubuntu/Debian OSV, they provide [intel-media-va-driver-non-free](https://packages.ubuntu.com/search?keywords=intel-media-driver-non-free&searchon=sourcenames) (Full feature build) and [intel-media-va-driver](https://packages.ubuntu.com/search?keywords=intel-media-driver&searchon=sourcenames) (Free kernel build) two packages. ***Free*** here means open source kernel but not related to fee need to pay. You could refer to [build options](https://github.com/intel/media-driver?tab=readme-ov-file#build-options) for more detail.

If you are looking forward to have a big table to share media component features on these two builds, below tables are good referene for your information.

- \* VP8 decoding is only supported on TGL platform
- D  - Hardware Decoding
- E  - Hardware Encoding, Low Power Encoding(VDEnc/Huc)
- Es - Hardware(PAK) + Shader(media kernel+VME) Encoding

***Note:*** Low Power Encoding(VAEntrypointEncSliceLP) and Shader Encoding(VAEntrypointEncSlice) are consolidated to the unified interface(VAEntrypointEncSlice) from ***MTL*** platform. It goes through VDEnc/Huc for HW acceleration to unleash GPU resource to customers.

## Build Options

Media-driver supports different build types as described below. You could refer to
the following settings to enable them.
- **Full Feature Build**: ENABLE_KERNELS=ON(Default) ENABLE_NONFREE_KERNELS=ON(Default)
- **Free Kernel Build**: ENABLE_KERNELS=ON ENABLE_NONFREE_KERNELS=OFF
    - If trying to use pre-built open source kernel binaries, please add BUILD_KERNELS=OFF(Default).
    - If trying to rebuild open source kernel from source code, please add BUILD_KERNELS=ON.

Media-driver requires special i915 kernel mode driver (KMD) version to support the following platforms since upstream version of i915 KMD does not fully support them(pending patches upstream). To enable these platforms, it requires to specify `ENABLE_PRODUCTION_KMD=ON` (default: `OFF`) build configuration option.
- DG1/SG1
- ATSM


## Backward Compatibility
No code changes may be introduced that would regress support for any currently supported hardware.
All contributions must ensure continued compatibility and functionality across all supported hardware platforms.
Failure to maintain hardware compatibility may result in the rejection or reversion of the contribution.

Any deliberate modifications or removal of hardware support will be transparently communicated in the release notes.

API options are solely considered as a stable interface.
Any debug parameters, environmental variables, and internal data structures, are not considered as an interface and may be changed or removed at any time.


## Known Issues and Limitations

1. Intel(R) Media Driver for VAAPI is recommended to be built against gcc compiler v6.1
or later, which officially supported C++11.

2. HuC firmware is necessary for AVC/HEVC/VP9/AV1 low power encoding bitrate control, including CBR, VBR, etc. The [default kernel configuration](https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/i915/gt/uc/intel_uc.c#L21) didn't enable HuC loading for TGL/RKL and legacy platforms but enabled it from ADL+ platforms. You could change the HuC setting with ```"options i915 enable_guc=2" > /etc/modprobe.d/i915.conf``` under root. For ADL+ platforms, the kernel loads HuC as default if the [related platform HuC binary](https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915) exists in ```/lib/firware/i915```. The HuC firmwares available on different platforms are:
   - APL/KBL: starting from kernel 4.11, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - CFL: starting from kernel 4.15, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - ICL: starting from kernel 5.2, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - EHL/JSL: starting from kernel 5.8, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - TGL: starting from kernel 5.9, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - RKL: starting from kernel 5.17, HuC loading is disabled as default, so set `i915.enable_guc=2`
   - ADL-S/ADL-P: starting from kernel 5.17
   - ADL-N/RPL-S/RPL-P: starting from kernel 6.2
   - DG1/SG1: [intel-gpu/intel-gpu-i915-backports](https://github.com/intel-gpu/intel-gpu-i915-backports)
   - Alchemist(DG2): starting from kernel 6.2
   - ATSM: [intel-gpu/intel-gpu-i915-backports](https://github.com/intel-gpu/intel-gpu-i915-backports)
   - MTL/ARL: starting from kernel 6.8
   - LNL: [intel/xe-kernel](https://gitlab.freedesktop.org/drm/xe/kernel)
