Sebastian Huber started a new discussion on bsps/aarch64/shared/start/start.S: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/113#note_112155 > _el1_start: > > #ifdef RTEMS_SMP > - /* Read MPIDR and get current processor index */ > - mrs x7, mpidr_el1 > - and x7, x7, #0xff > + ldr x3, =aarch64_cpu_boot_params The approach with this table is quite complicated and not necessary for most systems. Why can't you simply call a function which is provided by the BSP? For example: ``` #ifdef RTEMS_SMP bl _AArch64_Get_current_processor ... ``` The default implementation is: ``` FUNCTION_ENTRY(_AArch64_Get_current_processor) mrs x0, mpidr_el1 and x0, x0, #0xff FUNCTION_END(_AArch64_Get_current_processor) ``` -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/113#note_112155 You're receiving this email because of your account on gitlab.rtems.org.
