There's a problem with the combination of the upstream power management fixes and the enabling of MSI by default in that the suspend path still uses the global variable.

SGI machines with WD33C93 allow usage of burst mode DMA, which increases performance noticable. To make this selectable by the sgiwd93 stub, setting the values for no_sync, fast and dma_mode has been moved to the individual platform stubs. Signed-off-by:

While performing hardware raid reset testing via the raid's client, I noticed that sometimes, following the reset, that there would be more raid targets in the lsscsi output than there actually were raid targets. I tracked this down to the following issue. Fusion cannot always find the mptsas_portinfo structure for the hba because it uses the handle stored in ioc->handle to locate it. The problem is that the firmware can change the handle associated with the hba when h/w raid is reset (via the raid client). When this happens, the driver will allocate another mptsas_portinfo structure and link it into the chain of said structures. This ultimately causes confusion within the driver resulting in targets not being removed when they should be. Eric Moore pointed out that the hba's portinfo structure is always the first structure on the sas_topology list. This patch modifies mptsas.c to access the hba's portinfo structure by taking the first structure on said list. Signed-off-by:

This patch contains the following: 1. when hba completion status is good, check for iscsi transport errors (underflow/overflow) prior to checking the scsi status 2. New firmware requires that one marker iocb be issued for each task management command. The patch issues marker iocb immediately following a LUN or Target reset. Signed-off-by:

This fixes a bug that we treat all sequencer operations as ands and never do the additional invalid bit checks non-and operations require because the if () to determine this has an operand which is always true at the end of the or statement. Signed-off-by:

Two functions, sdebug_add_adapter and devInfoReg, creates new scsi_debug devices. To simplify the code, this patch adds a new helper function to create new scsi_debug devices (sdebug_device_create) and converts both functions to use it. I plan to add more to scsi_debug devices (e.g. using a thread for a scsi_debug device for scalability testings). This patch enable me to add such to just the new helper function instead of touching two functions, sdebug_add_adapter and devInfoReg. Signed-off-by:

Since the way we allocate commands with a separate sense buffer is getting complicated, we should isolate setup and teardown to a single routine so that if it gets even more complex, there's only one place in the code that needs to be altered. Signed-off-by: -

LLDs need to copies data between the SG table in struct scsi_cmnd and liner buffer. So they use the helper functions like sg_copy_from_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) sg_copy_to_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) This patch just adds wrapper functions: scsi_sg_copy_from_buffer(sc, buf, buflen) scsi_sg_copy_to_buffer(sc, buf, buflen) Signed-off-by:

This patch adds new three helper functions to copy data between an SG list and a linear buffer. - sg_copy_from_buffer copies data from linear buffer to an SG list - sg_copy_to_buffer copies data from an SG list to a linear buffer When the APIs copy data from a linear buffer to an SG list, flush_kernel_dcache_page is called. It's not necessary for everyone but it's a no-op on most architectures and in general the API is not used in performance critical path. Signed-off-by:

We've verified that there are 64 bit and endianness problems in the flashpoint driver. Reverse the logic of CONFIG_OMIT_FLASHPOINT (make it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't appear for any other architectures. Long term, if someone chooses, they could make FlashPoint 64 bit compliant (it looks like its a question of fixing up the sizes in some of the packed descriptors) Signed-off-by: -

When a FSF physical close returns the status boxed, this means that another system already closed the port. For our system this is the same status as in the good path, we have to send the normal close. So, set the status for the boxed response to the same as for the good status. Signed-off-by:
