2018-01-22scsi: hisi_sas: fix a bug in hisi_sas_dev_gone()Xiang Chen1-1/+0
When device gone, NULL pointer can be accessed in free_device callback if during SAS controller reset as we clear structure sas_dev prior. Actually we can only set dev_type as SAS_PHY_UNUSED and not clear structure sas_dev as all the members of structure sas_dev will be re-initialized after device found.

2018-01-22scsi: hisi_sas: directly attached disk LED feature for v2 hwXiaofei Tan3-0/+62
This patch implements LED feature of directly attached disk for v2 hw. As libsas has provided an interface lldd_write_gpio() for this feature, we just need realise the interface following SPGIO API. We use an CPLD to finish the hardware part of this feature, and the base address of CPLD should be configured through ACPI or DT tables.

2018-01-22scsi: megaraid_sas: NVMe passthrough command supportShivasharan S3-5/+62
NVMe passthrough via MFI interface. Current MegaRAID product supports different types of encapsulation via the MFI framework. NVMe native command should be framed by application and it should be embedded in MFI as payload. The driver will provide interface to send the MFI frame along with the payload (in this case, payload is NVMe native command) to the firmware. Driver already has an existing, similar interface for SATA and SMP passthrough. 1. Driver will pass MFI command to the firmware if the latter supports NVMe encapsulated processing (not all SAS3.5 firmware supports this feature). 2. Driver exposes sysfs entry support_nvme_encapsulation. This is required for backward compatibility for applications using earlier driver versions that did not process IOCTL frames and could result in host hang. This is already fixed as part of commit 82add4e1b354 ("scsi: megaraid_sas: Incorrect processing of IOCTL frames for SMP/STP commands") [mkp: clarified commit message] Signed-off-by: Sumit Saxena <sumit.saxena@broadcom.com> Signed-off-by: Shivasharan S <shivasharan.srikanteshwara@broadcom.com> Signed-off-by: Martin K.

When driver is not able to get reqeusted IRQs from the system, driver will attempt tp clean up memory before failing hardware probe.

2018-01-17scsi: scsi_debug: delay stress fixDouglas Gilbert1-26/+46
Introduce a state enum into sdebug_defer objects to indicate which, if any, defer method has been used with the associated command. Also add 2 bools to indicate which of the defer methods has been initialized. Those objects are re-used but the initialization only needs to be done once. This simplifies command cancellation handling. Now the delay associated with a deferred response of a command cannot be changed (once started) by changing the delay (and ndelay) parameters in sysfs. Command aborts and driver shutdown are still honoured immediately when received.
