The driver was previously marked 'broken' and 'harmful'; the new findings show it actually consumes more CPU than simply doing hashing directly on the CPU. A patch removing all ~3,500 lines of the QCE driver has been submitted, though at least one developer wants to keep it. Greg Kroah-Hartman has been brought in to weigh in on the decision. ## Full article daily.dev links to this article rather than hosting it.
