*
|
|
* Test Type: Feature based
|
|
*
|

*
|
|
* Steps:
|
|
* - Initialize a VM with the following characteristics:
|
|
* - 64KB large page support enabled
|
|
* - Low hole size = 64MB
|
|
* - Address space size = 128GB
|
|
* - Kernel reserved space size = 4GB
|
|
* - Map a 4KB buffer into the VM
|
|
* - Check that the resulting GPU virtual address is aligned to 4KB
|
|
* - Unmap the buffer
|
|
* - Map a 64KB buffer into the VM
|
|
* - Check that the resulting GPU virtual address is aligned to 64KB
|
|
* - Unmap the buffer
|
|
* - Uninitialize the VM
