Intel's Open Source Vulkan Driver
|
||||
Vulkan API Version: 1.0.2
|
||||
SPIR-V Version: 1.0
|
||||
|
||||
Intro
|
||||
=====
|
||||
The Open Source Technology Center 3D graphics team at Intel has
|
||||
been working on a Vulkan implementation based on the Mesa open source
|
||||
OpenGL implementation.
|
||||
|
||||
The Mesa project source and our driver implementation is under the MIT
|
||||
license [1], but is also covered by the Khronos IP framework as it
|
||||
pertains to a specification under construction [2].
|
||||
|
||||
We welcome all feedback and contibutions, as long as the contributions
|
||||
are MIT licensed and can be open sourced with the driver.

Supported Hardware
|
||||
==================
|
||||
- Broadwell & Sky Lake, main development focus
|
||||
- Ivybridge
|
||||
- Haswell
|
||||
- Bay Trail
|
||||
- Cherryview
|
||||
- Broxton
|
||||
|
||||
|
||||
Conformance
|
||||
===========
|
||||
First-wave conformance has been submitted for Broadwell, Sky Lake, and
|
||||
Cherryview. They all pass 100% of the mustpass tests as of January 30,
|
||||
2016.
|
||||
|
||||
|
||||
Supported OS Platforms
|
||||
======================
|
||||
- Linux, tested on Fedora 22 with kernel >= 4.1
|
||||
- X11 with DRI3
|
||||
- Wayland
|
||||
- Android
|
||||
- TODO
|
||||
|
||||
|
||||
Building and Installing
|
||||
=======================
|
||||
This driver is intended to be used directly from the build tree. Installing the
|
||||
driver into a system location is not yet fully supported. If you require support
|
||||
for system-wide installation, please contact a maintainer.
|
||||
|
||||
Throughout the instructions, MESA_TOP refers to the top of the Mesa repository.
|
||||
|
||||
First, install the usual dependencies needed to build Mesa.
|
||||
|
||||
Fedora:
|
||||
$ sudo yum builddep mesa
|
||||
Ubunutu:
|
||||
$ FINISHME
|
||||
|
||||
Next, configure and build. The below commands will build Mesa in release mode.
|
||||
If you wish to build Mesa in debug mode, add option '--enable-debug' to the
|
||||
configure command.
|
||||
|
||||
$ cd $MESA_TOP
|
||||
$ autoreconf -vfi
|
||||
$ ./configure --with-dri-drivers=i965 --with-gallium-drivers=
|
||||
$ make
|
||||
|
||||
To use the driver's libvulkan.so directly, without LunarG's loader, you must set
|
||||
an environment variable before running your Vulkan application:
|
||||
|
||||
$ export LD_LIBRARY_PATH="$MESA_TOP/lib"
|
||||
$ your-vk-app
|
||||
|
||||
Alternatively, to use the driver with LunarG's loader:
|
||||
|
||||
$ export VK_ICD_FILENAMES="$MESA_TOP/src/vulkan/anv_icd.json"
|
||||
$ your-vk-app
|
||||
|
||||
|
||||
File Structure and Naming
|
||||
=========================
|
||||
The core code of Intel's Mesa Vulkan driver lives in src/vulkan. Files prefixed
|
||||
with "gen8" support Broadwell; files prefixed with "gen7" support Ivybridge;
|
||||
files prefixed with "anv" are common to all hardware generations.
|
||||
|
||||
Mesa is an umbrella open source project containing many drivers for multiple
|
||||
APIs. The codename for Intel's Mesa Vulkan driver is "Anvil", hence the filename
|
||||
prefix "anv".
|
||||
|
||||
|
||||
Feature Status
|
||||
==============
|
||||
The driver is still a work-in-progress. We do our best to keep the below list of
|
||||
features up-to-date.
|
||||
|
||||
Supported Features:
|
||||
- Index buffers, instanced draw, indirect draw
|
||||
- Nested command buffers
|
||||
- Consumes SPIR-V (no GLSL "backdoor")
|
||||
- Fragment, vertex, geometry, and compute shaders
|
||||
- Uniform buffers, sampled images, dynamic uniform buffers
|
||||
- Shader storage buffers
|
||||
- Push constants
|
||||
- Color, depth and stencil attachments
|
||||

|
||||

|
||||
- Optionally integrates with LunarGs loader
|
||||
- WSI extension for X11
|
||||
