| commit 528cef1b4170f328d28d4e9b437380d8e5a2d18f upstream. |
| |
| Ensure a non-interruptible wait is used when moving a bo to |
| XE_PL_SYSTEM. This prevents dma_mappings from being removed prematurely |
| while a GPU job is still in progress, even if the CPU receives a |
| signal during the operation. |
