header.context is a 64 bit field, but it's deliberately split into context and context_hi32. Thus cpu_to_le64 assignments are wrong on this. Replace them with the correct settings of both the low and high words. Cc: HighPoint Linux Team <linux@highpoint-tech.com> Signed-off-by: -

Currently, the maximum amount of RAM that scsi_debug can allocate is 4GB. This patch increases it to 2TB; scsi_debug can allocates 2TB memory and export it as if it were 2TB scsi disk. Signed-off-by:

This patch adds per request hardware debugging data to the trace record which is written per request. It's a replacement for some sad kernel message based debugging code. Considering the amount of trace data, printk() is not suitable for this stuff. Writing binary traces is more efficient. In addition we got all information in one place. The QTCB trace data is only dumped for requests other than SCSI requests. Otherwise we would flood the trace ring buffer. We are mostly interested in non-SCSI, recovery related requests here anyway. This patch also works around a known hardware bug. It truncates QTCB traces so that we do not save unused areas of the hardware trace. 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:

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:
