This generates memory pressure with multi-process VM Bind activity and concurrent submission, exercising the bind pipeline under eviction pressure. v7: Save errno immediately in create_test_bos before it can be clobbered. Handle non-ENOMEM/ENOSPC failures in create_test_bos. Remove dead code (retries == 0 check) in xe_exec_with_retry. Add igt_skip when both vram and sram n_bufs are 0. Add MAP_FAILED check on result_bo.ptr after xe_bo_map. (Nishit) v8: Add error check while performing vmbind. v9: Assert if vmbind fails for VRAM/ SRAM. Moved wait fence for vm bind immediately after call. v10:Add igt_debug() message when batch_bo bind fails with ENOMEM/ENOSPC Added check for failed bind aganist ENOMEM/ENOSPC.
