* [SCSI] mptfusion: mpt config will do Hard Reset based upon retry countsKashyap, Desai2010-04-11
| | | | | | | | | mpt_config would only attempt a MUR before retrying the command. The driver will now retry a second time with a hard reset before leaving the function. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] mptfusion: Added new less expensive RESET (Message Unit Reset)Kashyap, Desai2010-04-11
| | | | | | | | | | | | | | | | Message Unit Reset - instructs the IOC to reset the Reply Post and Free FIFO's. All the Message Frames on Reply Free FIFO are discarded. All posted buffers are freed, and event notification is turned off. IOC doesnt reply to any outstanding request. This will transfer IOC to READY state. Message unit ready is less expensive operations than Hard Reset. soft reset will not force Firmware to reload again, it only do clean up of Message units. mpt_Soft_Hard_ResetHandler will first try for Soft Reset,if it fails then go for big hammer reset which is Hard Reset.

* [SCSI] mptsas: Fix issue with chain pools allocation on katmaiAnatolij Gustschin2010-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources.Pravin Bathija2009-12-10
| | | | | | | | | | | | | | 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.

* [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory regionKashyap, Desai2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason for this change is there is a data corruption when four different physical memory regions in the 36GB to 37GB region are accessed. This is only affecting 1078. The solution is we need to use different addressing when filling in the scatter gather table for the effected memory regions. So instead of snooping on all four different memory holes, we treat any physical addresses in the 36GB address with the same algorithm. The fix is explained below 1) Ensure that the message frames are NOT located in the trouble region. There is no remapping available for message frames, they must be allocated outside the problem region. 2) Ensure that Sense buffers are NOT in the trouble region. There is no remapping available. 3) Walk through the SGE entries and if any are inside the trouble region then they need to be remapped as discussed below. 1) Set the Local Address bit in the SGE Flags field. MPI_SGE_FLAGS_LOCAL_ADDRESS 2) Ensure we are using 64-bit SGEs 3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer location is Host Memory.

The SPI controllers are fine, but are likely to be onboard on older motherboards which don't handle MSI correctly, so default both these cases to disabled.

* [SCSI] mpt fusion: fix two potential mem leaksJesper Juhl2007-10-12
| | | | | | | | | | | | | | | | | | The Coverity checker spotted two potential memory leaks in drivers/message/fusion/mptbase.c::mpt_attach(). There are two returns that may leak the storage allocated for 'ioc' (sizeof(MPT_ADAPTER) bytes). A simple fix would be to simply add two kfree() calls before the return statements, but a better fix (that this patch implements) is to reorder the code so that if we hit the first return condition we don't have to do the allocation at all and then just add a kfree() call for the second case.
