* Test specification for test_writel_check

*
|
|
* Description: Write value v to reg and read it back.
|
|
*
|
|
* Test Type: Feature
|
|
*
|
|
* Targets: nvgpu_writel_check
|
|
*
|
|
* Inputs: None
|
|
*
|
|
* Steps:
|
|
* Initialize address space and register io callbacks.
|
|
* Call nvgpu_writel_check with value 0. Here read and write value will be
|
|
* different as read callback always returns NVGPU_READ_VAL.
|
|
* Call nvgpu_writel_check with value NVGPU_READ_VAL. Here read and write value
|
|
* will be same as read callback always returns NVGPU_READ_VAL.
|
|
*
|
|
* Output:
|
|
* The test returns PASS only as target nvgpu_writel_check() always returns
|
|
* void.
