Data Fields | |
Objects_Control | Object |
Thread_queue_Control | Join_queue |
Thread queue for thread join operations and multi-purpose lock. More... | |
States_Control | current_state |
Priority_Node | Real_priority |
The base priority of this thread in its home scheduler instance. | |
Thread_Scheduler_control | Scheduler |
Scheduler related control. | |
Thread_Wait_information | Wait |
Thread_Timer_information | Timer |
Context_Control | Registers |
This member contains the context of this thread. More... | |
bool | is_idle |
bool | is_preemptible |
bool | is_fp |
bool | was_created_with_inherited_scheduler |
True, if the thread was created with an inherited scheduler (PTHREAD_INHERIT_SCHED), and false otherwise. | |
Thread_CPU_budget_control | CPU_budget |
This member contains the CPU budget control used to manage the CPU budget of the thread. | |
Timestamp_Control | cpu_time_used |
This member contains the amount of CPU time consumed by this thread since it was created. | |
Timestamp_Control | cpu_time_used_at_last_reset |
This member contains the amount of CPU time consumed by this thread at the time of the last reset of the CPU usage by rtems_cpu_usage_reset(). | |
Thread_Start_information | Start |
Thread_Action_control | Post_switch_actions |
Context_Control_fp * | fp_context |
struct _reent * | libc_reent |
void * | API_Extensions [THREAD_API_LAST+1] |
Thread_Keys_information | Keys |
The POSIX Keys information. | |
Thread_Life_control | Life |
Thread life-cycle control. More... | |
Thread_Capture_control | Capture |
struct rtems_user_env_t * | user_environment |
Pointer to an optional thread-specific POSIX user environment. | |
struct _pthread_cleanup_context * | last_cleanup_context |
LIFO list of POSIX cleanup contexts. | |
struct User_extensions_Iterator * | last_user_extensions_iterator |
LIFO list of user extensions iterators. | |
void * | extensions [RTEMS_ZERO_LENGTH_ARRAY] |
Variable length array of user extension pointers. More... | |
This structure defines the Thread Control Block (TCB).
Uses a leading underscore in the structure name to allow forward declarations in standard header files provided by Newlib and GCC.
In case the second member changes (currently Join_queue), then the memset() in _Thread_Initialize() must be adjusted.
void* _Thread_Control::API_Extensions[THREAD_API_LAST+1] |
This array contains the API extension area pointers.
States_Control _Thread_Control::current_state |
This field is the current execution state of this thread.
void* _Thread_Control::extensions[RTEMS_ZERO_LENGTH_ARRAY] |
Variable length array of user extension pointers.
The length is defined by the application via <rtems/confdefs.h>.
Context_Control_fp* _Thread_Control::fp_context |
This field points to the floating point context for this thread. If NULL, the thread is integer only.
bool _Thread_Control::is_fp |
This field is true if the thread uses the floating point unit.
bool _Thread_Control::is_idle |
This field is true if the thread is an idle thread.
bool _Thread_Control::is_preemptible |
This field is true if the thread is preemptible.
Thread_queue_Control _Thread_Control::Join_queue |
Thread queue for thread join operations and multi-purpose lock.
The lock of this thread queue is used for various purposes. It protects the following fields
struct _reent* _Thread_Control::libc_reent |
This field points to the newlib reentrancy structure for this thread.
Thread_Life_control _Thread_Control::Life |
Thread life-cycle control.
Control state changes triggered by thread restart and delete requests.
Objects_Control _Thread_Control::Object |
This field is the object management structure for each thread.
Context_Control _Thread_Control::Registers |
This member contains the context of this thread.
This member is placed directly after the end of the common block so that the structure offsets are as small as possible. This helps on instruction set architectures with a very limited range for intermediate values.
Thread_Start_information _Thread_Control::Start |
This field contains information about the starting state of this thread.
Thread_Timer_information _Thread_Control::Timer |
This field is the Watchdog used to manage thread delays and timeouts.
Thread_Wait_information _Thread_Control::Wait |
This field is the blocking information for this thread.
