Details

Package pipelinecache provides shared disk persistence helpers for GPU driver pipeline caches (Vulkan VkPipelineCache and DX12 cached PSO blobs).

This package is internal to wgpu. Backends own cache lifecycle; this package only handles adapter-scoped paths and atomic blob I/O.

func DX12AdapterKey(luidLow uint32, luidHigh int32, vendorID, deviceID, revision uint32) string

DX12AdapterKey identifies a DXGI adapter for cache scoping.

func DeleteBlob(path string) error

DeleteBlob removes a cache blob. Missing files are ignored.

func HexKey(parts ...[]byte) string

HexKey returns a hex-encoded SHA-256 digest of the given byte slices.

func LoadBlob(path string) ([]byte, error)

LoadBlob reads a cache blob from disk. A missing file returns (nil, nil).

func SaveBlob(path string, data []byte) error

SaveBlob atomically writes a cache blob to disk (write temp + rename).

func UserCachePath(backend, adapterKey, fileName string) (string, error)

UserCachePath returns an adapter-scoped cache file path under os.UserCacheDir(). Example: ~/.cache/gogpu/vulkan/<adapterKey>/pipeline.cache

func VulkanAdapterKey(vendorID, deviceID, driverVersion uint32, uuid [16]byte) string

VulkanAdapterKey identifies a Vulkan physical device for cache scoping.
