ZTEST() [1/3]

ZTEST	(	interrupt_feature	,
		test_isr_offload_job
	)

Test interrupt offload work by dynamic interrupt.

Validate isr can offload workload to work queue, and the offload jobs could execute immediately base on it's priority. We test this by dynamic interrupt.

ZTEST() [2/3]

ZTEST	(	interrupt_feature	,
		test_isr_offload_job_identi
	)

Test interrupt offload work to identical jobs.

Validate isr can offload workload to work queue, and all the offload jobs use the same thread entry, and:

• If the priority of the original thread < offload job, offload jobs could execute immediately.
• If the priority of the original thread >= offload job, offload jobs will not execute immediately.

We test this by irq_offload().

ZTEST() [3/3]

ZTEST	(	interrupt_feature	,
		test_isr_offload_job_multiple
	)

Test interrupt offload work to multiple jobs.

Validate isr can offload workload to multi work queue, and:

• If the priority of the original thread < offload job, offload jobs could execute immediately.
• If the priority of the original thread >= offload job, offload jobs will not execute immediately.

We test this by irq_offload().
