os/kernel: Update sysdbg availabe in current TizenRT
- Updated sysdbg structures to support multiple CPUs by adding arrays for scheduling and IRQ history. - Modified sysdbg_print to display task and IRQ scheduling history per CPU. - Updated sysdbg to use spin_lock_irqsave() instead of enter_critical_section(), because enter_critical_section makes recursive call. - enter_critical_section() -> up_cpu_paused_restore() -> up_restoretask() -> save_task_scheduling_status() -> enter_critical_section() - spin_lock_irqsave blocks interrupt and provides SMP-safe protection for sysdbg_struct without the enter_critical_section() - This patch makes sysdbg available in current TizenRT system. [Configuration Example] ``` CONFIG_DEBUG_SYSTEM=y CONFIG_IRQ_SCHED_HISTORY=y CONFIG_SEMAPHORE_HISTORY=y CONFIG_TASK_SCHED_HISTORY=y CONFIG_DEBUG_IRQ_MAX_COUNT=0x20 CONFIG_DEBUG_SEM_MAX_COUNT=0x20 CONFIG_DEBUG_TASK_MAX_COUNT=0x20 CONFIG_DEBUG_SYSTEM_APP=y ``` [Log Example] ``` TASH>>sysdbg help TASH>>show_usage: USAGE: show_usage: sysdbg enable_monitor /* Allocates memory and enables monitoring */ show_usage: sysdbg disable_monitor /* Frees the memory and disables monitoring */ show_usage: sysdbg read /* Reads /dev/sysdbg to view debug information*/ show_usage: sysdbg max_task_count <count> /* Enter max_task_count */ show_usage: sysdbg max_irq_count <count> /* Enter max_irq_count */ show_usage: sysdbg max_sem_count <count> /* Enter max_sem_count */ show_usage: sysdbg data_abort /*
