* [SCSI] mpt2sas: Timeout occurred within the HANDSHAKE logic while waiting on ↵Kashyap, Desai2009-10-021-3/+1
| | | | | | | | | | | | | | | | firmware to ACK. Following a diag_reset, a request to send an ioc_init is timing out. The timeout occurred within the HANDSHAKE logic while waiting on firmware to acknowledge that the driver had wrote to the doorbell register. This was root caused to a logic timeout in the firmware code. The proposed solution is for the driver to call the udelay instead of msleep API in function where its looping reading the interrupt status. In addition to this change, there were two additional cases where we deleted the clearing interrupt status outside handshake context.

* [SCSI] mpt2sas: Call init_completion on a per request basis.Kashyap, Desai2009-10-023-3/+10
| | | | | | | | | | | | Now driver call init_completion on a per request basis. At some point the wait_for_completion_timeout is not waiting for the timeout, instead returning immediately, thus going into diag reset. This fix will address all request using the wait_for_completion_timeout API. The previous implimentation was only calling init_completion at driver load time.

* [SCSI] mpt2sas: Target Reset will be issued from Interrupt context.Kashyap, Desai2009-10-026-54/+372
| | | | | | | | | | | | | | | | | | (1) Added three new functions to handle sending target resest and OP_REMOVE from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and _scsih_sas_control_complete. This code will create a link list of pending target resets if there is no more available request in the hipriority request queue. The list is stored in ioc->delayed_tr_list. (2) All callback handler return type is changed from void to u8. Now _base_interrupt will check for return type of callback handlers to take decision of message frame is already freed or not. In genral, Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from function.

* [SCSI] mpt2sas: Added SCSIIO, Internal and high priority memory pools to ↵Kashyap, Desai2009-10-024-137/+307
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | support multiple TM 1) create a pool of high priority message frames in the region of memory between message frames and chains. The modifications are in _base_allocate_memory_pools. Also create a seperate pool of memory for internal commands located near the same region of memory. The pool of high priority message frames is restriced by the facts->HighPriorityCredit. 2) Create additional API for accessing request message frames. New function mpt2sas_base_get_smid_hpr is for highpriority request. New function mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command pointer. The mpt2sas_base_get_smid function is for requesting internal commands. 3) Added new function _base_get_cb_idx to obtain the callback index from one of the three pools of request message frames. 4) Removed wrapper functions _scsih_scsi_lookup_set and _scsih_scsi_lookup_getclear. These were removed because this handling was moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid. 5) The function mpt2sas_base_free_smid is modified so the request message frames are put back on one of the three pools of request message frames.

| | | | | | | | | | | | | | When a volume is activated, the driver will recieve a pair of ir config change events to remove the foreign volume, then add the native. In the process of the removal event, the hidden raid componet is removed from the parent.When the disks is added back, the adding of the port fails becuase there is no instance of the device in its parent. To fix this issue, the driver needs to call mpt2sas_transport_update_links() prior to calling _scsih_add_device.

The conversion was done under the assumption that when a request fails residue count wasn't defined. However, Boaz and James pointed out that this wasn't true and the residue count should be preserved for failed requests too. This patchset restores the original behavior by setting rq->resid_len to blk_rq_bytes(rq) on request start and restoring explicit clearing in affected drivers.

This duality creates some headaches. First of all, block layer and low level drivers can't really determine what rq->data_len contains while a request is executing. It could be the total request length or it coulde be anything else one of the lower layers is using to keep track of residual count. This complicates things because blk_rq_bytes() and thus [__]blk_end_request_all() relies on rq->data_len for PC commands. Drivers which want to report residual count should first cache the total request length, update rq->data_len and then complete the request with the cached data length. Secondly, it makes requests default to reporting full residual count, ie. reporting that no data transfer occurred. The residual count is an exception not the norm; however, the driver should clear rq->data_len to zero to signify the normal cases while leaving it alone means no data transfer occurred at all. This reverse default behavior complicates code unnecessarily and renders block PC on some drivers (ide-tape/floppy) unuseable. This patch adds rq->resid_len which is used only for residual count. While at it, remove now unnecessasry blk_rq_bytes() caching in ide_pc_intr() as rq->data_len is not changed anymore.

* | [SCSI] mpt2sas: fix hotplug event processingEric Moore2009-04-271-5/+5
| | | | | | | | | | | | | | | | | | | | Here's a fix for hotplug events. The useage of queue_delayed_work seems to broke the fifo for processing of firmware events. After several iterations of adding and removing cabling connected to jbods, the devices are not getting added becuase kernel thread is activited out of order.

* | [SCSI] mpt2sas : release diagnotic buffers prior host resetEric Moore2009-04-272-70/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Diagnostic buffer support is already there in the driver. This support allows applications to pull ring buffers from controller firmware for debugging firmware related issues. What this patch does is sends reqeust to firmware to release the buffers prior to host reset. This will allow what ever debug info is there prior to reset to be dma'd to host memory. With out this fix, some of the debug data would been lost. Signed-off-by: Eric Moore <eric.moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* | [SCSI] mpt2sas : Broadcast Primative AEN bug fixEric Moore2009-04-271-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix in the broadcast primative async event code where the driver would stop sending tm queries after the first queury was completed. This was due driver not reseting the tm_cmds.status field back to MPT2_CMD_NOT_USED after completing a task management request. An addtional fix adding sanity check to insure sas_device->starget set to NULL. During multipath testing fail over/fail back, the mid layer was holding onto sdev longer than the fail back period, thus starget was getting set to NULL for device being added.

* | [SCSI] mpt2sas : driver name needs to be in the MPT2IOCINFO ioctlEric Moore2009-04-271-3/+3
| | | | | | | | | | | | | | | | | | The driver name needs to be at the beginining of the driver_version string in MPT2IOCINFO ioctl. This is the same behaviour is there already in the mptsas driver.

* | [SCSI] mpt2sas : running out of message framesEric Moore2009-04-271-1/+3
| | | | | | | | | | | | | | | | | | The driver is not freeing message frame when returning failure from _ctl_do_task_abort. If you call this function 500 times when its unable to find an active task mid, you end up with no message frames.

* | [SCSI] mpt2sas : fix oops when firmware sends large sense buffer sizeEric Moore2009-04-271-1/+2
| | | | | | | | | | | | | | | | | | | | There is a bug in firmware where the reply message frame says there is a 16kb sense buffer, when in reality its only 20 bytes. This fix insures the memcpy action doesn't corrupte the memory beyond the 90 bytes allocated in the scsi command for sense buffer.

* | [SCSI] mpt2sas : the sanity check in base_interrupt needs to be on dword ↵Eric Moore2009-04-271-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | boundary The poison sanity check on the reply_post_free register needs to be by 32bit, not 64bit. The poison check is there because its possible that the driver read the 1st 32bit before the 2nd 32bit has been written to by firmware. In other words, this handles race between driver reading the 64 bit register, and it being dma'd across pci memory from controller firmware as two 32bit pci writes.
