[PATCH 01/34] scsi: drop gdth driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter
which was manufactured by the now-defunct ICP Vortex company, later
acquired by Adaptec and superseded by the aacraid series of controllers.
The driver itself would require a major overhaul before any modifications
can be attempted, but seeing that it's unlikely to have any users left
it should rather be removed completely.

- * rescan:Y                     rescan all channels/IDs 
- * rescan:N                     use all devices found until now
- * hdr_channel:x                x - number of virtual bus for host drives
- * shared_access:Y              disable driver reserve/release protocol to 
- *                              access a shared resource from several nodes, 
- *                              appropriate controller firmware required

- * force_dma32:Y                use only 32 bit DMA mode
- * force_dma32:N                use 64 bit DMA mode, if supported
