2010-01-17[SCSI] mptsas: Fix issue with chain pools allocation on katmaiAnatolij Gustschin1-0/+2
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.

2009-12-10[SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources.Pravin Bathija1-3/+3
Powerpc 44x uses 36 bit real address while the real address defined in MPT Fusion driver is of type 32 bit. This causes ioremap to fail and driver fails to initialize. This fix changes the data types representing the real address from unsigned long 32-bit types to resource_size_t which is 64-bit. The driver has been tested, the disks get discovered correctly and can do IO.

2009-12-04[SCSI] modify change_queue_depth to take in reason why it is being calledMike Christie2-3/+9
This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> [Vasu.Dev: v2 Also converted pmcraid_change_queue_depth and then verified all modules compile using "make allmodconfig" for any new build warnings on X86_64.

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.

2009-09-12[SCSI] mptsas : FW event thread and scsi mid layer deadlock in SYNCHRONIZE ↵Kashyap, Desai1-7/+1
CACHE command 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. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
