Functions

```
void PushDriver (const void * driver, driver_runtime::Dispatcher * dispatcher)
```
Adds |driver| to the thread's current call stack.

Defined at line 97 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
void PopDriver ()
```
Removes the driver at the top of the thread's current call stack.

The stack must not be empty.

Defined at line 113 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
const void * GetCurrentDriver ()
```
Returns the driver at the top of the thread's current call stack,

or null if the stack is empty.

Defined at line 125 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
driver_runtime::Dispatcher * GetCurrentDispatcher ()
```
Returns the dispatcher at the top of the thread's current call stack,

or null if the stack is empty.

Defined at line 130 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
void SetDefaultTestingDispatcher (driver_runtime::Dispatcher * dispatcher)
```
Sets the default dispatcher to return in GetCurrentDispatcher

when the driver context stack is empty. Only meant for testing.

Defined at line 135 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
bool IsDriverInCallStack (const void * driver)
```
Returns whether |driver| is in the thread's current call stack.

Defined at line 140 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
bool IsCallStackEmpty ()
```
Returns whether the thread's current call stack is empty.

Defined at line 149 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
uint32_t GetIrqGenerationId ()
```
Returns the latest generation id seen by the current thread.

Defined at line 151 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
void SetIrqGenerationId (uint32_t id)
```
Sets the latest generation id seen by the current thread.

Defined at line 153 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
std::optional<zx_status_t> GetRoleProfileStatus ()
```
Returns the result of setting the role profile for the current thread.

May be std::nullopt if no attempt has been made to set the role profile.

Defined at line 155 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
void SetRoleProfileStatus (zx_status_t status)
```
Sets the result of setting the role profile for the current thread.

Defined at line 157 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
zx::result<const void *> GetDriverOnTid (zx_koid_t tid)
```
Defined at line 159 of file ../../src/devices/bin/driver_runtime/thread_context.cc
```
std::pair<zx_koid_t, std::atomic_int64_t *> GetTaskEntryTimeSlot ()
```
Gets the thread koid and the storage for the current thread's task

entry time slot, which will be:

-1 if no entry time has been recorded yet.

0 if the task has since exited its callback.

N>0 a timestamp when this thread was last entered.
