* [SCSI] ibmvscsi: Add eh_host_reset_handlerBrian King2007-06-171-30/+106
| | | | | | | | | | | Adds an eh_host_reset_handler to ibmvscsi which resets the connection to the vscsi server. This patch also adds a timer to internally issues commands to prevent client hangs in the case of a misbehaving server. Tested by modifying the VIOS such that it would occasionally drop one or more request in sequence.

* [SCSI] ibmvscsi: Enhanced error loggingBrian King2007-06-171-117/+91
| | | | | | | | | | | | | | | | Converts ibmvscsi to use dev_printk and friends to simplify debugging. ibmvscsi adapter initialization now looks like this: ibmvscsi 30000005: SRP_VERSION: 16.a ibmvscsi 30000005: partner initialization complete ibmvscsi 30000005: sent SRP login ibmvscsi 30000005: SRP_LOGIN succeeded Additionally, this patch adds the logging of a couple return codes in a couple logs.

* [SCSI] ibmvscsi: Remove unnecessary map_sg checkBrian King2007-06-171-7/+0
| | | | | | | | | Since sg_tablesize is set appropriately in the scsi host template, remove the unnecessary check to make sure it is not exceeded following the dma_map_sg call. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] ibmvscsi: add slave_configure to allow device restartRobert Jennings2007-04-011-0/+22
| | | | | | | | | | | | Fixed the kernel-doc comment for ibmvscsi_slave_configure. Thanks to Randy Dunlap for pointing this out. Adding a slave_configure function for the driver. Now the disks can be restarted by the scsi mid-layer when the are disconnected and reconnected.

* [SCSI] ibmvscsi: allow for dynamic adjustment of server request_limitRobert Jennings2007-04-011-20/+38
| | | | | | | | | | | The request limit calculations used previously on the client failed to mirror the state of the server. Additionally, when a value < 3 was provided there could be problems setting can_queue and handling abort and reset commands.

* [SCSI] ibmvscsi: correctly reenable CRQSantiago Leon2006-10-251-1/+1
| | | | | | | | | | | | The "ibmvscsi: treat busy and error conditions separately" patch submitted by Dave Boutcher back in June incorrectly reenables the CRQ. The broken logic causes the adapter to get disabled if the CRQ connection happens to close temporarily. This patch "fixes that obviously wrong logic check" (Dave's words).

* [SCSI] ibmvscsi: treat busy and error conditions separatelyDave C Boutcher2006-06-261-15/+49
| | | | | | | | | This patch fixes a condition where ibmvscsi treats a transport error as a "busy" condition, so no errors were returned to the scsi mid-layer. In a RAID environment this means that I/O hung rather than failing over. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] ibmvscsi: prevent scsi commands being sent in invalid stateDave C Boutcher2006-04-131-1/+3
| | | | | | | | | | | | There is a window where we can be re-enabling an adapter, but still allow SCSI commands to be sent to the target. This fix sets our window (request_limit) to -1 as soon as we know the adapter is being reenabled, and closes a very teeny tiny window where we could set the window back to 1 before we grab a lock.

* [SCSI] ibmvscsi: handle re-enable firmware messageDave C Boutcher2006-01-261-31/+36
| | | | | | | | | | New versions of the Power5 firmware can send a "re-enable" message to the virtual scsi adapter. This fix makes us handle the message correctly.

* [SCSI] ibmvscsi compatibility fixDave C Boutcher2005-09-131-0/+10
| | | | | | | | | | | | | | Linda Xie ever so gently pointed out that she had a patch to preserve compatibility with older SLES targets, and I told her we didn't need to push it to mainline. This patch explicitly checks the version of the IBMVSCSI target and ensures that large scatterlists are not sent to older targets.

| | | | | | | | | | | | | | | | | | | | | | | | | | The maximum size of a scatter-gather list that the current IBM VSCSI Client can handle is 10. This patch adds large scatter-gather support to the client so that it is capable of handling up to SG_ALL(255) number of requests in the scatter-gather list.

| * [SCSI] ibmvscsi timeout fixDave C Boutcher2005-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a long term borkenness in ibmvscsi where we were using the wrong timeout field from the scsi command (and using the wrong units.) Now broken by the fact that the scsi_cmnd timeout field is gone entirely. This only worked before because all the SCSI targets assumed that 0 was default.

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!
