%description
Original AMD SDK 1.1.4 raw FSR 3.1.4 upscaler, optical flow and frame
interpolation APIs with explicit downstream Linux portability patches.
The Windows interpolation swapchain is excluded. Installing this library
does not enable frame generation in games or the desktop.

%package devel
Summary:        Matched Linux context headers for raw FidelityFX effects
Requires:       %{name}%{?_isa} = %{version}-%{release}
Requires:       vulkan-headers

%description devel
Headers and link metadata for the experimental native Vulkan library.
The opaque context ABI differs from the original Windows headers.

%package tests
Summary:        CPU checks and opt-in bounded GPU pipeline diagnostics
Requires:       %{name}%{?_isa} = %{version}-%{release}
Requires:       bash
Requires:       systemd

%description tests
Native C++ API and compatibility checks plus an explicitly invoked GPU
pipeline diagnostic. No test starts automatically. The GPU diagnostic
does not dispatch an effect, generate frames or measure presentation.
