Functions

CosmOS_SpinlockStateType CILspinlock_trySpinlock(AddressType *spinlockPointer, BitWidthType spinlockId, BitWidthType schedulableId)¶

Try to get spinlock. This function cannot be called from the unprivileged context directly. DEMO.

The implementation contains function HAL_HSEM_Take call intended to take hardware semaphore based on the spinlock identifier and schedulable unique identifier. If the hsemTakeStatus is equal to the the value 1 is loaded to the spinlock address and spinlockState is set to the SPINLOCK_STATE_ENUM__SUCCESSFULLY_LOCKED. Otherwise is spinlockState set to the SPINLOCK_STATE_ENUM__OCCUPIED. In the end is the spinlockState returned from the function.

Parameters

spinlockPointer – [in] pointer to the spinlock variable that stores spinlock value
spinlockId – [in]
schedulableId –

Returns

CosmOS_SpinlockStateType

CosmOS_SpinlockStateType CILspinlock_releaseSpinlock(AddressType *spinlockPointer, BitWidthType spinlockId, BitWidthType schedulableId)¶

Release spinlock. This function cannot be called from the unprivileged context directly. DEMO.

The implementation contains function HAL_HSEM_Release call intended to release hardware semaphore based on the spinlock identifier and schedulable unique identifier. Then the value 0 is loaded to the spinlock address and spinlockState is set to the SPINLOCK_STATE_ENUM__RELEASED and returned from the function.

Parameters

spinlockPointer – [in] pointer to the spinlock variable that stores spinlock value
spinlockId – [in]
schedulableId –

Returns

CosmOS_SpinlockStateType
