workqueue: CPU hotplug keep idle workers 2012-08-13T21:49:54+00:00 Mitch Luban mluban@nvidia.com 2012-07-25T19:59:04+00:00 9dfdd9ac17ac9955b431cb962df3d0492384ba0e This change merges two patchsets. The first set, containing 6 patches, reimplements WQ_HIGHPRI to use a seperate worker_pool. gcwq->pools[0] is used for normal priority work and pools[1] for high priority. The second patchset contains 9 patches and reimplements CPU hotplug to keep idle workers. Updates workqueue CPU hotplug path to use a disassociated global_cwq, which runs as an unbound one (WQ_UNBOUND). While this requires rebinding idle workers, overall hotplug path is much simpler.

The only sane way to do this is to use a identity mapping for the device and not translate it by the iommu. This is implemented with this patch. Since this lifts the device-isolation there is also a new kernel parameter which allows to disable that feature. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
