* [SCSI] ipr: Support new device queueing modelbrking@us.ibm.com2005-11-062-11/+66
| | | | | | | | | | | | | | | New ipr adapters support a new device queueing model in the adapter firmware. The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue. The new queueing model removes this complexity. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] ipr: Module parm to disable RAID 0 auto createbrking@us.ibm.com2005-11-061-0/+5
| | | | | | | | | | Some ipr adapters will automatically create single device RAID 0 arrays for all unconfigured RAID capable devices found at adapter initialization time. This patch adds a module parameter to disable this behavior. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] ipr: Runtime resetbrking@us.ibm.com2005-11-062-1/+5
| | | | | | | | | | | Some IPR RAID adapter will automatically create single device RAID arrays for all attached devices when the card is initialized. Setting the RUNTIME_RESET doorbell bit will prevent this from occurring, since we only want this behavior the first time the card is initialized and not each time the card happens to get reset.

| | | | | | | | | | | If the write buffer command that is issued to the ipr adapter to update its microcode fails for some reason, the DMA buffer will never get unmapped. Move the pci_map/unmap out of the IOA reset job so that the buffer is always clearly mapped and unmapped.

* [SCSI] ipr: Disk array rescanning fixbrking@us.ibm.com2005-11-061-0/+1
| | | | | | | | | | | | | | | | IPR RAID arrays show up on a virtual scsi bus, with a scsi bus number of 255, which is generated by the adapter microcode. For the initial scan of the host, we manually scan this bus since it does not obey SAM in regards to sparse LUNs and the disk array devices do not have a consistent product id to use scsi core's blacklist. If /proc/scsi/scsi or sysfs is used to delete one of these devices, the device will not be able to get added back by rescanning the host since scsi core will see ipr's max_channel as 4, rather than 255. Update max_channel after the initial scan so that ipr raid arrays can get re-added if they get deleted.

| | | | | | | | | | | | | | | | | "Medium not present" This patch started life as a response to fedora specific ide subsystem changes that made error handling of my ATAPI tape drive fail; the specifics are in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868 The insertion of the statement rq->errors = err; near the end of ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c anymore.

| | | | | | | | | | | | There's an oops that sometimes shows up with SCSI transport classes in sysfs_hash_and_remove. The problem is that now, because of the class to device and vice versa symlinks, all classes have to be removed from visibility *before* the device is removed from visibility. The transport class trigger points violate this, so bring them back into conformance. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver takes a reference only for requests coming by way of the gendisk, not for requests coming by way of the struct device or struct scsi_device. Such requests can arrive in the rescan, flush, and shutdown pathways. The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used).

| | * [SCSI] ips: Fix initialization bug with kdumpJack Hammer2005-10-311-0/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I/O is active on the adapter, and an unexpected interrupt is pending during initialization, the driver blows it's brains out. Since the driver didn't initiate the I/O, the data in it's internal tables will contain NULL pointers. When this condition is detected, a "flush cache and reset" is performed. The flush cache allows any pending "lazy writes" that the adapter is processing to complete ( a "must have" for a RAID adapter ) and the reset puts the adapter back into a known, good state.
