* [SCSI] mptlan: bug fix, only half the message frame is dma'd resulting in ↵Eric Moore2007-10-12
| | | | | | | | | | | | | | | | | | corruption NB = number of blocks. This represents the number of blocks to transfer. The block size is based on the message frame size provided in the ioc_facts. A value of zero indicates the entire message frame should be copied. This is two bit value. So by setting this to non-zero vaule, you increase performance by reducing amount of data needing to be dma'd. The value that is stored in ioc->ReqeustNB is sometimes a non-zero vaule, which creates a bug in mptlan, where not the entire message frame is getting transfer to firware, resulting in corruption. This fix sets the default to zero, thus entire message frame is copied. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] mpt fusion: lock down ScsiLookupEric Moore2007-10-12
| | | | | | | | | | | | ScsiLookup is an array of pending scmd pointers that the scsi lld maintains. This array is touched from queuecommand, eh threads, and interrupt context. This array should put under locks, hence this patch to synchronize its access. I've added some nice little function wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER struct.

| | | | | | | | | | | | This patch just makes the version number in ips.c and ips.h consistent. It seems that this has been forgotten in a60768e2d43eb30a1adb8a119aeac35dc0d03ef6.

* [SCSI] ncr53c8xx: Call scsi_host_put in releaseMatthew Wilcox2007-10-12
| | | | | | | | | | | | | | Since ncr53c8xx_attach() calls scsi_host_put(), make ncr53c8xx_release() call scsi_host_put() too, for symmetry. Both callers already expect it to put the host for them, so that works out nicely. While the zalon driver does 'use' the host pointer afterwards, it only compares it for equality and doesn't dereference it, so that's safe. While I'm at it, get rid of pointless checks for NULL, use shost_priv() and change ncr53c8xx_release to return void.

* [SCSI] sg: use idr to replace static arraysJames Bottomley2007-10-12
| | | | | | | | | | | | sg uses a scheme to reallocate a single contiguous array of all its pointers for lookup and management. This didn't matter too much when sg could only attach 256 nodes, but now the maximum has been bumped up to 32k we're starting to push the limits of the maximum allocatable contiguous memory. The solution to this is to eliminate the static array and do everything via idr, which this patch does.

* [SCSI] qla2xxx: Rework MSI-X handlers.Andrew Vasquez2007-10-12
| | | | | | | | | | | | | | Since MSI-X vectors do not require a clearing "handshake" from the system perspective, and the registered handler will not be called more than once for one occurrence of receipt of a vector, there is no requirement to flush the risc register write clearing the interrupt condition in the risc. Also, since the msi-x registered handlers are optimised for a particular vector, it is preferable to handle the one vector received per invocation of the handler.

* [SCSI] move ULD attachment into the prep functionJames Bottomley2007-10-12
| | | | | | | | | | | | | | | One of the intents of the block prep function was to allow ULDs to use it for preprocessing. The original SCSI model was to have a single prep function and add a pointer indirect filter to build the necessary commands. This patch reverses that, does away with the init_command field of the scsi_driver structure and makes ULDs attach directly to the prep function instead. The value is really that it allows us to begin to separate the ULDs from the SCSI mid layer (as long as they don't use any core functions---which is hard at the moment---a ULD doesn't even need SCSI to bind).
