- * For the avoidance of doubt the "preferred form" of this code is one which
- * is in an open non patent encumbered format. Where cryptographic key signing
- * forms part of the process of creating an executable the information
- * including keys needed to generate an equivalently functional executable
- * are deemed to be part of the source code.
- *
- * Complications for I2O scsi
- *
- * o Each (bus,lun) is a logical device in I2O. We keep a map
- * table. We spoof failed selection for unmapped units
- * o Request sense buffers can come back for free.
- * o Scatter gather is a bit dynamic. We have to investigate at
- * setup time.
- * o Some of our resources are dynamically shared. The i2o core
- * needs a message reservation protocol to avoid swap v net
- * deadlocking. We need to back off queue requests.
- *
- * In general the firmware wants to help. Where its help isn't performance
- * useful we just ignore the aid. Its not worth the code in truth.
- *
- * Fixes/additions:
- * Steve Ralston:
- * Scatter gather now works
- * Markus Lidel <Markus.Lidel@shadowconnect.com>:
- * Minor fixes for 2.6.
- *
- * To Do:
- * 64bit cleanups
- * Fix the resource management problems.
