|
15 // Overview: |
|
16 // Test the video driver kernel extension that provides chunk handle to access video memory. |
|
17 // This executable is a second process that is started by the main t_videomemory test process. |
|
18 // API Information: |
|
19 // HAL, UserSvr |
|
20 // Details: |
|
21 // - Check that we can get a chunk and that we can read/write the memory belonging to that chunk. |
|
22 // - When this process exits, the main process will check that the value has changed in it's copy |
|
23 // - of the chunk. |
|
24 // Platforms/Drives/Compatibility: |
|
25 // All. |
|
26 // Assumptions/Requirement/Pre-requisites: |
|
27 // Failures and causes: |
