vk-force-priority

vk-force-priority allows you to control the global priority of any vulkan application.

Building from Source

Dependencies

Before building, you will need:

  • GCC >= 9
  • Vulkan Headers

Building

These instructions use --prefix=/usr, which is generally not recommened since the .so will be installed in directories that are meant for the package manager. The alternative is not setting the prefix, it will then be installed in /usr/local. But you need to make sure that ld finds the library since /usr/local is very likely not in the default path.

In general, prefer using distro provided packages.

git clone https://github.com/DadSchoorse/vk-force-priority.git
cd vk-force-priority

64bit

meson --buildtype=release --prefix=/usr builddir
ninja -C builddir install

32bit

Make sure that PKG_CONFIG_PATH=/usr/lib32/pkgconfig and --libdir=lib32 are correct for your distro and change them if needed. On Debian based distros you need to replace lib32 with lib/i386-linux-gnu, for example.

ASFLAGS=--32 CFLAGS=-m32 CXXFLAGS=-m32 PKG_CONFIG_PATH=/usr/lib32/pkgconfig meson --prefix=/usr --buildtype=release --libdir=lib32 -Dwith_json=false builddir.32
ninja -C builddir.32 install

Usage

ENABLE_VKPRIORITY=1 VK_PRIORITY=medium yourcommand

Possible VK_PRIORITY values are low, medium, high or realtime. high and realtime might fail with VK_ERROR_NOT_PERMITTED_EXT.
