From d36deae75011a7890f0e730dd0f867c64081cb50 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Tue, 7 Sep 2010 21:14:39 +0000 Subject: qdio: extend API to allow polling Extend the qdio API to allow polling in the upper-layer driver. This is needed by qeth to use NAPI. To use the new interface the upper-layer driver must specify the queue_start_poll(). This callback is used to signal the upper-layer driver that is has initiative and must process the inbound queue by calling qdio_get_next_buffers(). If the upper-layer driver wants to stop polling it calls qdio_start_irq(). Since adapter interrupts are not completely stoppable qdio implements a software bit QDIO_QUEUE_IRQS_DISABLED to safely disable interrupts for an input queue. The old interface is preserved and will be used as is by zfcp. Signed-off-by: Jan Glauber Signed-off-by: Martin Schwidefsky Signed-off-by: Frank Blaschka Signed-off-by: David S.
