Frequently Asked Questions
1
What condition is required to trigger the issue?
An allocation request must set the doorbell ID to a specific value. This option is used by CRIU, and the supplied value was not checked to ensure it was below KFD_MAX_NUM_OF_QUEUES_PER_PROCESS.
2
How can I determine whether a kernel includes the fix?
The resolved code checks that a specifically requested doorbell ID is less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS. The listed stable-kernel references identify commits containing the correction.
