EGL: Refactor multifile blobcache (b81ab201) · Commits · e / os / android_frameworks_native

After more testing, it became apparent that we need to avoid accessing the filesystem to have decent speed. This CL does that by: * Moving the multifile cache to a class * Tracking all entries in a bookkeeping system * Remove use of STL for read/write * Keep recent entries in a hot cache * Deferring file writes to a worker thread * Allowing devices to opt in via config For more data and details on the design philosophy: go/improving-multifile-blobcache-speed Also added a new sequence of tests that bypass EGL and directly invoke the mulfifile cache.
