__aligned()

uint8_t init_drv_data[160] ipc_user::__aligned

(

4

)

User-accessible copy of comp_driver + tr_ctx for create().

The comp_driver and tr_ctx structs reside in kernel memory (.rodata/.data) which is not user-readable. The kernel handler copies them here before forwarding to the user thread. Size verified by BUILD_ASSERT in handler-user.c.
