An external fragmentation event was previously described as

Despite the earlier patches, external fragmentation events are still
inevitable as not all callers can stall or are appropriate to stall
(e.g. unmovable allocations that kswapd reclaim will not necessarily
help). In the event there is a mixed pageblock, it's desirable to move all
movable pages from
The page allocator zone lists are iterated based on the watermarks
of each zone which does not take anti-fragmentation into account. On
x86, node 0 may have multiple zones while other nodes have one zone. A
consequence is that tasks running on node 0 may fragment ZONE_NORMAL even

Sure. Basically, my approach is sort-of eventfd-e

Don't you think a system call would be better than a new ioctl? With
either an ioctl or a new system

Perhaps add missing braces for the last else uses as well?

This is the implementation of the VFIO ioctl calls to handle
the AQIC interception and use GISA to handle interrupts.

We define two VFIO ioctl command to setup and clear
the AP Queues interrupt.
Arguments passed by the guest are:
- the apqn, AP queue number
- the Notification by address
- the identifier of the previously associated adapter

This is the first version to handle AP Interrupt
using the GISA facility.
The patch series is based on the GISA+GIB patch series
sent by Michael Mueller.
- We define a new VFIO ioctl to ask the vfio_ap driver to register
a interruption for the guest.
- We define the assembler code to register a

Tested with fio on a 2 socket AMD EPYC based server with 128 cores and 8 nvme
drives. Comparing baseline linux-next kernel results with linux-next with this
patch applied IOPS increased by 40%.
