target: Minimize #include directives

2016-12-09T18:22:28+00:00

Remove superfluous #include directives from the include/target/*.h files. Add missing #include directives to other *.h and *.c files. Use forward declarations for structures where possible. This change reduces the build time for make M=drivers/target on my laptop from 27.1s to 18.7s or by about 30%. Signed-off-by: Bart Van Assche Cc: Christoph Hellwig Cc: Bryant G. Ly

cxgbit: Use type ISCSI_CXGBIT + cxgbit tpg_np attribute

2016-05-17T05:23:59+00:00

Instead of having cxgbit use type ISCSI_HW_OFFLOAD + 'hw_offload' tpg_np attribute, it should be using it's own driver specific type + attribute Cc: Varun Prakash Cc: Hariprasad Shenai Cc: Christoph Hellwig Cc: Sagi Grimberg Signed-off-by: Nicholas Bellinger

iscsi-target: Convert transport drivers to signal rdma_shutdown

2016-05-17T05:23:33+00:00

Instead of special casing the handful of callers that check for iser-target rdma verbs specific shutdown, use a simple flag at iscsit_transport->rdma_shutdown so each driver can signal this. Also, update iscsi-target/tcp + cxgbit to rdma_shutdown = false. Cc: Varun Prakash Cc: Hariprasad Shenai Cc: Christoph Hellwig Cc: Sagi Grimberg Signed-off-by: Nicholas Bellinger

iscsi-target: export symbols

2016-05-10T06:12:28+00:00

export symbols for ISCSI_HW_OFFLOAD transport drivers. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: add new offload transport type

2016-05-10T06:12:18+00:00

Add new transport type ISCSI_HW_OFFLOAD, hw offload transport drivers will use this transport type. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: move iscsit_thread_check_cpumask()

2016-05-10T06:12:09+00:00

Move iscsit_thread_check_cpumask() to header file so that ISCSI_HW_OFFLOAD and other transport drivers can call this function to ensure both tx and rx thread runs on same cpu. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: add void (*iscsit_get_r2t_ttt)()

2016-05-10T06:12:08+00:00

Add void (*iscsit_get_r2t_ttt)() to struct iscsit_transport, iscsi-target uses this callback to get r2t->targ_xfer_tag. cxgbit.ko needs this callback for Direct Data Placement of Data Out pdus, adapter uses ttt in Data Out pdus for placing data directly in to the host buffers.

iscsi-target: add int (*iscsit_validate_params)()

2016-05-10T06:12:08+00:00

Add int (*iscsit_validate_params)() to struct iscsit_transport, iscsi-target uses this callback for validating conn operational parameters. cxgbit.ko needs this callback to check and update the value of MAXXMITDATASEGMENTLENGTH. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: add void (*iscsit_get_rx_pdu)()

2016-05-10T06:12:07+00:00

Add void (*iscsit_get_rx_pdu)() to struct iscsit_transport, iscsi-target uses this callback to receive and process Rx iSCSI PDUs. cxgbit.ko needs this callback to reuse iscsi-target Rx thread. Signed-off-by: Varun Prakash Acked-by: Sagi Grimberg Signed-off-by: Nicholas Bellinger

iscsi-target: add void (*iscsit_release_cmd)()

2016-05-10T06:12:06+00:00

Add void (*iscsit_release_cmd)() to struct iscsit_transport, iscsi-target uses this callback to release transport driver resources associated with an iSCSI cmd. cxgbit.ko needs this callback to release DDP resource and sg page in case of PASSTHROUGH_SG_TO_MEM_NOALLOC.
