Detailed Description
The following defines the control block used to manage each thread proxy.
- Note
- It is critical that proxies and threads have identical memory images for the shared part.
Field Documentation
◆ Active
| Chain_Node Thread_Proxy_control::Active |
This field is used to manage the set of proxies in the system.
Referenced by _Thread_MP_Free_proxy().
◆ current_priority
| Priority_Control Thread_Proxy_control::current_priority |
This field is the current priority state of this thread.
Writes to this field are only allowed in _Thread_Initialize() or via _Thread_Change_priority().
◆ current_state
| States_Control Thread_Proxy_control::current_state |
This field is the current execution state of this proxy.
◆ Object
| Objects_Control Thread_Proxy_control::Object |
This field is the object management structure for each proxy.
◆ priority_generation
| uint32_t Thread_Proxy_control::priority_generation |
Generation of the current priority value.
It is used in _Thread_Change_priority() to serialize the update of priority related data structures.
◆ priority_restore_hint
| bool Thread_Proxy_control::priority_restore_hint |
Hints if a priority restore is necessary once the resource count changes from one to zero.
This is an optimization to speed up the mutex surrender sequence in case no attempt to change the priority was made during the mutex ownership. On SMP configurations atomic fences must synchronize writes to Thread_Control::priority_restore_hint and Thread_Control::resource_count.
◆ real_priority
| Priority_Control Thread_Proxy_control::real_priority |
This field is the base priority of this thread.
Writes to this field are only allowed in _Thread_Initialize() or via _Thread_Change_priority().
◆ resource_count
| uint32_t Thread_Proxy_control::resource_count |
This field is the number of mutexes currently held by this proxy.
◆ Timer
| Watchdog_Control Thread_Proxy_control::Timer |
This field is the Watchdog used to manage proxy delays and timeouts.
◆ Wait
| Thread_Wait_information Thread_Proxy_control::Wait |
This field is the blocking information for this proxy.
