2012-11-30	s390/pci: PCI adapter interrupts for MSI/MSI-X	Jan Glauber	1	-0/+1
	Support PCI adapter interrupts using the Single-IRQ-mode. Single-IRQ-mode disables an adapter IRQ automatically after delivering it until the SIC instruction enables it again. This is used to reduce the number of IRQs for streaming workloads. Up to 64 MSI handlers can be registered per PCI function. A hash table is used to map interrupt numbers to MSI descriptors. The interrupt vector is scanned using the flogr instruction. Only MSI/MSI-X interrupts are supported, no legacy INTs.

2012-09-26	s390/cio: add eadm subchannel driver	Sebastian Ott	1	-0/+1
	This driver allows usage of EADM subchannels. EADM subchannels act as a communication vehicle for SCM increments. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-12-25	[S390] zcrypt: Use of Thin Interrupts	Felix Beck	1	-0/+1
	When the machine supports AP adapter interrupts polling will be switched off at module initialization and the driver will work in interrupt mode. Signed-off-by: Felix Beck <felix.beck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
