Tim Van Patten b55f0f78 2020-06-02T18:01:24 Compress Program binaries saved in blob cache The Android blob cache has a limit of 2MB, so ANGLE should compress the Program binaries that are saved into it to maximize its effectiveness. ANGLE will gzip the program binaries before being stored in the blob cache and then uncompress them when retrieved. Using gzip, the binaries are compressed to ~25% of their size when running the T-Rex benchmark. Some examples (in bytes): Uncompressed: 20193, Compressed: 4455 Uncompressed: 8767, Compressed: 2369 Uncompressed: 11144, Compressed: 2927 This doesn't appear to affect the T-Rex benchmark since all of the programs are loaded/decompressed as part of the benchmark initialization, and the programs are small enough to all fit in the blob cache without compression.

Shahbaz Youssefi 37d2e606 2019-01-10T12:46:16 Make BlobCache use independent from ANGLE_program_cache_control The decision to enable caching or not was based on the size of the cache as directed by eglProgramCacheResizeANGLE, which is incorrect for applications that only use the ANDROID_blob_cache extension. The new behavior is as follows: - If EGL_CONTEXT_PROGRAM_BINARY_CACHE_ENABLED_ANGLE is specifically requested and set to true, but the size of the cache is 0, caching is disabled for the context. - If EGL_CONTEXT_PROGRAM_BINARY_CACHE_ENABLED_ANGLE is specifically requested and set to false, caching is disabled for the context. - Otherwise, caching is left enabled for the context, although the cache possibly has a size of zero, which effectively disables it. During application execution, if the blob cache callbacks are set, the application cache will be used.

Jamie Madill 35fd3063 2018-11-20T10:02:48 Use xxHash for faster hash map lookups. This most strongly affects the Vulkan back-end which uses a hash map to cache VkPipelines. It also should speed up some parts of the D3D11 back-end.

Shahbaz Youssefi 9137adea 2018-08-27T14:22:37 Add support for EGL_ANDROID_blob_cache The functionality of MemoryProgramCache is divided up in two. BlobCache is now a generic binary cache, which interfaces with the callbacks from EGL_ANDROID_blob_cache. MemoryProgramCache handles program [de]serialization and interacts with BlobCache.
