*	[S390] qdio: optimize cache line usage of struct qdio_irq	Jan Glauber	2010-02-26	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \|	Remove a memset hack that relied on the internal layout of the qdio_irq struct and move the per device statistics data into an own cache line to avoid cache line bashing between the inbound and the outbound queue tasklets. Also reduce the number of allocated queues from 32 to 4 which is the current maximum. That saves a cache line in struct qdio_irq.

*	[S390] qdio: Sanitize do_QDIO sanity checks	Jan Glauber	2009-06-22	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	Remove unneeded sanity checks from do_QDIO since this is the hot path. Change the type of bufnr and count to unsigned int so the check for the maximum value works.

*	[S390] qdio: report SIGA errors directly	Jan Glauber	2009-03-26	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Errors from SIGA instructions are stored in the per queue qdio_error and reported back when the queue handler is called. That opens a race when multiple error conditions occur simultanously. Report SIGA errors immediately in the return value of do_QDIO so the upper layer can react and SIGA errors no longer interfere with other errors. Move the SIGA error handling in qeth from the outbound handler to qeth_flush_buffers. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com>
*	[S390] qdio: fix qeth port count detection	Jan Glauber	2008-12-25	1	-8/+8
\| \| \| \| \| \| \| \| \| \|	qeth needs to get the port count information before qdio has allocated a page for the chsc operation. Extend qdio_get_ssqd_desc() to store the data in the specified structure. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	[S390] qdio enhanced SIGA (iqdio) support.	Klaus-Dieter Wacker	2008-10-10	1	-1/+7
\| \| \| \| \| \| \| \|	Add support for z10 HiperSockets multiwrite SBALs on output queues. This is used on LPAR with EDDP enabled devices. Signed-off-by: Klaus-Dieter Wacker <kdwacker@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
