PS5 FSR4 0.1.0

Experimental pre-release of the PS5 FSR4 port, built by GitHub Actions from
e7076ee75f765aad73267bd3b1535a69ef028b47 (Vulkan driver 188fa4a46ccbd09921f8a75942d83076c5a2a053).

Asset	Contents
ps5-fsr4-showcase-0.1.0-PPSA99010.zip	The PS5 FSR4 Showcase app, ready to install (see its README)
ps5-fsr4-sdk-0.1.0.zip	The ps5_fsr4 SDK for native PS5 applications
ps5-fsr4-0.1.0-source.tar.gz	Corresponding source: this repository with its Vulkan driver, ps5-agc-gears and the native app template
SHA256SUMS	SHA-256 of the assets

Install the showcase: extract the showcase zip, upload its PPSA99010 folder to
/data/homebrew/ on a PS5 running a homebrew loader with ShadowMountPlus, and start
PS5 FSR4 Showcase from the home screen once it is registered. It opens with a guided
tour; controls and performance.

Use the SDK: see FSR4_SDK.md in the SDK zip.

AMD / GPUOpen created FSR4. The INT8 optimizations come from the BC250 FSR4 project
(dmoraza and daniel-h-0 with contributors). This build is modified, unofficial and not
affiliated with or endorsed by AMD or Sony Interactive Entertainment. Each zip's
notices/ holds AMD's license and the provenance of the FSR4 material.

Build inputs (not an app release)

Inputs for the automated builds; not an app release.

• pipeline-cache-ps5-<sha256 prefix>.bin: the Vulkan pipeline cache a PS5 saved for the FSR4 pass tables and the driver that tools/build_inputs.json names (with its SHA-256, the pass tables' digest and the cache identity). The builds ship it so that the FSR4 pipelines load in about 0.1 s instead of compiling for about 85 s. It holds AMD FSR 4.1.1 shaders with the BC250 project's INT8 optimizations, modified and compiled for the PS5 GPU; that material is under the MIT terms of AMD-SDK-LICENSE.md.

A new cache is added here, under a new name, whenever the driver's compiler identity or the pass tables change (see docs/RELEASING.md).
