* [SCSI] introduce sfoo_printk, sfoo_id, sfoo_channel helpersJeff Garzik2005-10-281-0/+16
| | | | | | | | | | | | | | | | | | New dev_printk wrappers, which allow us to shrink code, and eliminate direct references to host/channel/id/lun members: scmd_printk() Introduce wrappers for highly common idioms, which may also help us eliminate some ->{channel,id} references in the future: {scmd,sdev}_id() {scmd,sdev}_channel() The scmd_* wrappers are present in scsi/scsi_device.h because they all employ the dereference chain cmd->device->$member. We would prefer to use static inline functions rather than macros, but that would have a Rejections fixed up and Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] sas: add flag for locally attached PHYsChristoph Hellwig2005-10-283-3/+13
| | | | | | | | | | | Add a flag to mark a PHY as attached to the HBA as opposed to beeing on an expander. This is needed because various features are only supported on those. This is a crude hack, the proper fix would be to use different classes for host-attached vs expander phys. I'm looking into that.

* [SCSI] qla2xxx: Add support to dynamically enable/disable ZIO.Andrew Vasquez2005-10-287-41/+146
| | | | | | | | | | | | | | | | | | ISP23xx and ISP24xx chips have support for an adaptive method of posting SCSI command completions for multiple SCSI commands during a single system interrupt. SCSI commands are placed on the system response queue without interrupting the host until 1) a delay timer expires; or 2) a SCSI command completes with an error. As long as the host software (qla2xxx) services the response queue for completions (this polling is done during queuecommand()) within the 'delay timer' period, the firmware will not generate system interrupt.

However, open-iscsi does not use MSG_MORE properly with sendpage, so NODELAY option hurts the open-iscsi performance. I've attached a patch to fix NODELAY and MSG_MORE problems and the write performance results with disktest. I use Opteron boxes connected directly, Chelsio NICs, 1500-byte MTU, 64 KB I/O size, and the iSCSI parameters on open-iscsi web site. With only NODELAY fix, the performance drops, as you said. On the other hand, NODELAY and MSG_MORE fixes improve the performance overall.
