* cciss: Consolidate duplicate bits in cciss_cmd.h & cciss_ioctl.hdann frazier2010-02-221-110/+3
| | | | | | | | | | | There are several duplicate definitions in cciss_cmd.h and cciss_ioctl.h. Consolidate these into the new cciss_defs.h file. This patch doesn't change the definitions exposed under include/linux, so userspace apps shouldn't be affected. Acked-by: Stephen M.

For controllers which supported, more than 512 scatter-gather elements per command may be used, and the max transfer size can be increased to 8192 blocks.

* cciss: Ignore stale commands after rebootHannes Reinecke2009-07-031-0/+1
| | | | | | | | | | | | | | | | | | When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

* cciss: kernel scan thread for MSA2012Mike Miller2009-04-071-0/+23
| | | | | | | | | | | | | | | The MSA2012 cannot inform the driver of configuration changes since all management is out of band. This is a departure from any storage we have supported in the past. We need some way to detect changes on the topology so we implement this kernel thread. In some instances there's nothing we can do from the driver (like LUN failure) so just print out a message. In the case where logical volumes are added or deleted we call rebuild_lun_table to refresh the driver's view of the world.

* [PATCH] cciss: direct lookup for command completionsMike Miller2005-09-131-2/+6
| | | | | | | | | | | | | This patch changes the way we complete commands. In the old method when we got a completion we searched our command list from the top until we find it. This method uses a tag associated with each command (not SCSI command tagging) to index us directly to the completed command. This helps performance.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+271
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
