Abstract

This invention discloses a TLS storage model compatibility method for heterogeneous closed-source driver integration. During system startup, a simulated memory pool and a native memory pool are constructed. When threads related to the heterogeneous closed-source driver are created, free storage blocks are allocated from both memory pools, and a thread mapping table is established. When a thread first accesses a TLS variable, the simulated storage block fields are initialized, and checksums for each region are calculated using a private salt value. The Android driver library performs verification on the simulated storage blocks. During thread execution, boundary function call timestamps are recorded, and valid records are filtered to calculate call probabilities. When a thread switches between Linux components and the Android driver library, the pre-switching is determined based on the boundary function call probabilities. During Android driver library operation, a field dependency graph is constructed for the private fixed field area of ​​the simulated memory pool, and the private fields are updated according to the graph rules. Ultimately, this achieves adaptation and compatibility of dual TLS layouts in heterogeneous environments and dynamic pre-switching management.
