mptspi: Fix for incorrect data underrun errata

2010-04-26T14:41:36+00:00

commit 9b53b39243cf23a0b68eaa16c37ce16eada69a46 upstream.

Errata:
Certain conditions on the scsi bus may casue the 53C1030 to incorrectly signal
a SCSI_DATA_UNDERRUN to the host.

Workaround 1:
For an Errata on LSI53C1030 When the length of request data
and transfer data are different with result of command (READ or VERIFY),
DID_SOFT_ERROR is set.

Workaround 2:
For potential trouble on LSI53C1030. It is checked whether the length of
request data is equal to the length of transfer and residual.
MEDIUM_ERROR is set by incorrect data.

SCSI: mptfusion : mptscsih_abort return value should be SUCCESS instead of value 0.

2010-02-23T15:37:55+00:00

commit 9858ae38011d699d4c2fa7f3493a47accf43a0f5 upstream.

retval should be SUCCESS/FAILED which is defined at scsi.h
retval = 0 is directing wrong return value. It must be retval = SUCCESS.

mptsas: Fix issue with chain pools allocation on katmai

2010-02-09T12:50:41+00:00

commit f1053a7ca9ce095d95bcc1cf41684c5e4f3e7751 upstream.

Since commit 9d2e9d66a3f032667934144cd61c396ba49f090d
mptsas driver fails to allocate memory for the MPT chain buffers
for second LSI adapter on PPC440SPe Katmai platform:
...
ioc1: LSISAS1068E B3: Capabilities={Initiator}
mptbase: ioc1: ERROR - Unable to allocate Reply, Request, Chain Buffers!
mptbase: ioc1: ERROR - didn't initialize properly! (-3)
mptsas: probe of 0002:31:00.0 failed with error -3

This commit increased MPT_FC_CAN_QUEUE value but initChainBuffers()
doesn't differentiate between SAS and FC causing increased allocation
for SAS case, too. Later pci_alloc_consistent() fails to allocate
increased chain buffer pool size for SAS case.

Provide a fix by looking at the bus type and using appropriate
MPT_SAS_CAN_QUEUE value while calculation of the number of chain
buffers.

headers: remove sched.h from interrupt.h

2009-10-11T18:20:58+00:00

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

[SCSI] mptsas : FW event thread and scsi mid layer deadlock in SYNCHRONIZE CACHE command

2009-09-12T14:35:28+00:00

Normally In HBA reset path MPT driver will flush existing work in current work
queue (mpt/0) . This is just a dummy activity for MPT driver point of
view, since HBA reset will turn off Work queue events.

It means we will simply returns from work queue without doing anything.
But for the case where Work is already done (half the way), we have to have
that work to be done.

Considering above condition we stuck forever since Deadlock in scsi midlayer
and MPT driver. sd_sync_cache() will wait forever since HBA is not in
Running state, and it will never come into Running state since
sd_sync_cache() is called from HBA reset context.
Now new code will not wait for half cooked work to be finished
before returning from HBA reset.

Once we are out of HBA reset, EH thread will change host state to running from
recovery and work waiting for running state of HBA will be finished.
New code is turning ON firmware event from another special work called
Rescan toplogy.

Driver is modified to return DID_NO_CONNECT for all pending I/O
requests for bus type SAS, if it founds the target is removed at
the firmware level.
