2008-07-12[SCSI] mpt fusion : Adding FAULT Reset polling workPrakash, Sathya
When the firmware is in Fault state it will be identifed only when the next time the driver access the IOC state. This patch includes a polling function in the driver which will be executed in regular interval to check the status of the firmware and if it is in Fault state, then the firmware will be reset by the driver.

2008-04-07[SCSI] mptsas: do not use ioc->handle to locate hba portinfo structureMichael Reed
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.

2008-02-11[SCSI] mpt fusion: Request I/O resources only when requiredPrakash, Sathya
This patch modifies the I/O resource allocation behavior of FUSION driver. The current version of driver allocates the I/O resources even if they are not required and this creates trouble in low resource environments. This driver now uses pci_enable_device_mem/pci_enable_device functions to differentiate the resource allocations.

2007-04-30[SCSI] fusion: fix domain validation loopsEric Moore
After host reset, the device are programmed to default asyn narrow nego. We need to reprogram the parameter back to previous values. If the host reset is called as a result of spi_dv_device() commands timing out, its possible to get into an infinite loop of dv to host reset. This will prevent that case, as we merely program old values. If host reset is called outside context of domain validation, then we can call spi_dv_device.

2007-02-02[SCSI] fusion - serialize target resets in mptsas.cEric Moore
Fusion firmware requires target reset following hotplug removal event, with purpose to flush target outstanding request in fw. Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes.

2006-06-30[SCSI] mptsas: eliminate ghost devicesJames Bottomley
One of the current problems the mptsas driver has is that of "ghost" devices (these are devices the firmware reports as existing, but what they actually represent are the parents of a lower device), so for example in my dual expander configuration, three expanders actually show up, two for the real expanders but a third is created because the firmware reports that the lower expander also has another expander connected (which is simply the port going back to the upper expander). The attached patch eliminates all these ghosts by not allocating any devices for them if the SAS address is the SAS address of the parent.

While doing board reset testing I was able to put the system in an infinite request/response loop between the scsi layer and mptscsih_qcmd() by aborting the reset. This patch installs a "SETUP RESET" handler which calls fc_remote_port_delete() for all registered rports. This blocks the target which prevents the loop. Additionally, should the reset fail to complete, the transport will now terminate i/o to the target.
