This is the code to actually support 64 bit platforms. 64 bit DMA is enabled on both x86_32 PAE and 64 bit platforms. This code is based in part on the unofficial adaptec 64-bit dpt_i2o driver update that I got from Mark Salyzyn at Adaptec. Signed-off-by:

Remove virt_to_bus/bus_to_virt code from dpt_i2o, and use dma_alloc_coherent() / dma_free_coherent(). This is in preparation of 64-bit support, dma_alloc_coherent() can allocate memory in the lower 32 bits of physical memory which is needed because the HBA only supports message blocks under 4GB This code is based in part on the unofficial adaptec 64-bit dpt_i2o driver update that I got from Mark Salyzyn at Adaptec.

Update dpt_i2o.c to use the standard __init / __exit code instead of the legacy '#include "scsi_module.c"' code. This is needed in preparation of 64-bit support. scsi_module.c calls scsi_add_host() with the device pointer set to NULL, and that crashes code like arch/x64/kernel/pci-gart_64.c::need_iommu(). The reboot_notifier code is deleted because it wasn't compiled in ever anyway, and it would be useless to duplicate it in the new code. Signed-off-by:

For firmware that supports the feature(s), add the ability to start or stop an array using the associated SCSI commands, to automatically manage the spin-up of an array on new I/O reporting back the appropriate check conditions and actions in cooperation with the normal timeout mechanisms and enable the blackout period management in the Firmware associated with the background spin-down of the arrays when the Firmware times out and deems the arrays as idle.

As JBOD devices (really just Simple Single Drive Volumes exported to the SCSI channel) are managed, they fail to update correctly when the driver triggers a SCSI scan. In addition, the ability to change multiple arrays or JBODs at the same time was resulting in dropped scans, set up a mechanism to issue a list of single target scans on a single configuration change notification from the Firmware. Performed some additional sundry cosmetic code style cleanups. Signed-off-by:

Add support for variable-length, extended, and vendor specific CDBs to scsi-ml. It is now possible for initiators and ULD's to issue these types of commands. LLDs need not change much. All they need is to raise the .max_cmd_len to the longest command they support (see iscsi patch). - clean-up some code paths that did not expect commands to be larger than 16, and change cmd_len members' type to short as char is not enough.

- struct scsi_cmnd had a 16 bytes command buffer of its own. This is an unnecessary duplication and copy of request's cmd. It is probably left overs from the time that scsi_cmnd could function without a request attached. So clean that up. - Once above is done, few places, apart from scsi-ml, needed adjustments due to changing the data type of scsi_cmnd->cmnd. - Lots of drivers still use MAX_COMMAND_SIZE. So I have left that #define but equate it to BLK_MAX_CDB. The way I see it and is reflected in the patch below is. MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB as per the SCSI standard and is not related to the implementation. BLK_MAX_CDB. - The allocated space at the request level - I have audit all ISA drivers and made sure none use ->cmnd in a DMA Operation. Same audit was done by Andi Kleen. (*)fixed-length here means commands that their size can be determined by their opcode and the CDB does not carry a length specifier, (unlike the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly true and the SCSI standard also defines extended commands and vendor specific commands that can be bigger than 16 bytes. The kernel will support these using the same infrastructure used for VARLEN CDB's. So in effect MAX_COMMAND_SIZE means the maximum size command scsi-ml supports without specifying a cmd_len by ULD's Signed-off-by: -

commit: commit 542bd137 Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Mon Apr 21 10:57:20 2008 -0500 [SCSI] fix SLUB WARN_ON Fixed another problem in free list handling by moving list allocation from scsi_host_alloc() to scsi_add_host(). Unfortunately it introduced a new failure mode in that hosts can pass straight from alloc to put without going through add, leaving the free list uninitialised. Fix by checking shost->cmd_pool on the release path to see if it got initialised. Signed-off-by:

Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.

Add a 'count' variable to each symbol which gets increased every time the symbol is referenced. And then modify the register definition to include counts for symbols which are referenced from the source code only and not from the sequencer code. This will give us an automatic usage count for the symbols with only minimal hand-crafting. Signed-off-by: -

The driver is incorrectly assuming that the 'sp' reference held in qla2[x00|4xx]_abort_command() is valid after the mailbox command is issued to abort the exchange. It is *not*, as the command may be completed during interrupt context before control is returned to the mailbox caller. Signed-off-by:

The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver. Signed-off-by:

Way back when, when the fc_user_scan routine was created, it kept some of its original logic that walked the rport list and kicked off a scan. Unfortunately, it didn't keep any of the locking around the rport list, nor did it consider the synchronous nature of the scan invoked. The result, there are some scan requests where the rport list changes, thus a subsequent scan is called on a bogus rport structure and the system NMI's. Signed-off-by:
