* Description: Functionalities of posix queue such as allocating and freeing

|

*
|

* Targets: nvgpu_queue_alloc, nvgpu_queue_free
|

*
|

* Input: None
|
||||
*
|
||||
* Steps:
|
||||
* - Pass NULL nvgpu_queue pointer as argument to nvgpu_queue_alloc() API and
|
||||
* check that the API returns "-EINVAL" error.
|
||||
* - Pass zero size queue length as argument to nvgpu_queue_alloc() API and
|
||||
* check that the API returns "-EINVAL" error.
|
||||
* - Pass "INT64_MAX" size queue length as argument to nvgpu_queue_alloc() API
|
||||
* and check that the API returns "-EINVAL" error.
|
||||
* - Inject fault so that immediate call to nvgpu_kzalloc() API would fail.
|
||||
* - Check that when the nvgpu_queue_alloc() API is called with valid arguments,
|
||||
* it would fail by returning "-ENOMEM" error.
|
||||
* - Remove the injected fault in nvgpu_kzalloc() API.
|
||||
* - Pass below valid arguments to nvgpu_queue_alloc() API and check that the
|
||||
* API returns success.
|
||||
* - Valid pointer to "struct nvgpu_queue"
|
||||
* - Queue size which is not power of 2
|
||||
* - Free the allocated queue by caling nvgpu_queue_free() API.
|
||||
* - Pass below valid arguments to nvgpu_queue_alloc() API and check that the
|
||||
* API returns success.
|
||||
* - Valid pointer to "struct nvgpu_queue"
|
||||
* - Queue size which is power of 2
|
||||
* - Free the allocated queue by caling nvgpu_queue_free() API.
|
||||
*
|
||||
* Output: Returns PASS if the steps above were executed successfully. FAIL
|

* otherwise.

|

* - Enqueue message of length "BUF_LEN" calling nvgpu_queue_in() API and check

|

* - Update "in" and "out" indexes and enqueue message of length BUF_LEN such
