Public bug reported: The GICv3 ITS table needs between 36K and 56K of contiguous memory. But, with 4K pages and a MAX_ZONEORDER of 11, we can only allocate 32K. The upstream approach to resolve this will likely be to make the core GIC a proper device that can use the DMA API:
http://www.spinics.net/lists/arm-kernel/msg487748.html However - that's a pretty big change, and will take a while to land. Until that time, I propose that we bump MAX_ZONEORDER up to 13 for the generic kernel. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: dann frazier (dannf) Status: Incomplete ** Changed in: linux (Ubuntu) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1558828 Title: Need enough contiguous memory to support GICv3 ITS table To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1558828/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
