linux-toradex.git/drivers/scsi/aacraid/rkt.c, branch v3.4.72 Linux kernel for Apalis and Colibri modules [SCSI] aacraid: Add new code for PMC-Sierra's SRC based controller family 2011-03-23T16:36:58+00:00 Mahesh Rajashekhara Mahesh_Rajashekhara@pmc-sierra.com 2011-03-17T09:10:32+00:00 e8b12f0fb8352237525961f14ec933e915848840 Added new hardware device 0x28b interface for PMC-Sierra's SRC based controller family. - new src.c file for 0x28b specific functions - new XPORT header required - sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT) - async. Interface: different inbound queue handling, no outbound I2O queue available, using doorbell ("PmDoorBellResponseSent") and response buffer on the host ("host_rrq") for status - changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending" bit to inform about pending AIF, "AifRequest" command to read AIF, "NoMoreAifDataAvailable" to mark the end of the AIFs Signed-off-by: Mahesh Rajashekhara <aacraid@pmc-sierra.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
