scsi: mpi3mr: Rework mrioc->bsg_device model to fix warnings

2022-06-02T02:23:09Z

During driver unload, mrioc->bsg_device reference count becomes negative. Also, as reported in [1], the driver's bsg_device model had few more bugs. Fix all these up.

scsi: mpi3mr: Add target device related sysfs attributes

2022-05-20T00:16:26Z

Add sysfs attributes for exposing target device details such as SAS address, firmware device handle, and persistent ID for the controller-attached devices and RAID volumes.

scsi: mpi3mr: Add shost related sysfs attributes

2022-05-20T00:16:26Z

Add shost related sysfs attributes to display the controller's firmware version, queue depth, number of requests, and number of reply queues. Also add an attribute to set & get the logging_level.

Return -ENOMEM instead of success if dma_alloc_coherent() fails. Link: https://lore.kernel.org/r/YnOmMGHqCOtUCYQ1@kili Fixes: 43ca11005098 ("scsi: mpi3mr: Add support for PEL commands") Signed-off-by: Dan Carpenter Signed-off-by: Martin K. Petersen

scsi: mpi3mr: Fix a NULL vs IS_ERR() bug in mpi3mr_bsg_init()

2022-05-17T01:30:17Z

The bsg_setup_queue() function does not return NULL. It returns error pointers. Fix the check accordingly. Link: https://lore.kernel.org/r/YnUf7RQl+A3tigWh@kili Fixes: 4268fa751365 ("scsi: mpi3mr: Add bsg device support") Signed-off-by: Dan Carpenter Signed-off-by: Martin K. Petersen

scsi: mpi3mr: Return I/Os to an unrecoverable HBA with DID_ERROR

2022-05-11T02:28:21Z

Complete all new I/O requests issued to an unrecoverable controller with DID_ERROR status instead of returning the I/O requests with SCSI_MLQUEUE_HOST_BUSY. This will prevent the infinite retries of the new I/Os when a controller is in an unrecoverable state.

scsi: mpi3mr: Hidden drives not removed during soft reset

2022-05-11T02:18:47Z

If any drive is missing during reset, the driver checks whether the device is exposed to the OS. If it is, then it removes the device from the OS and its own internal list. For hidden devices, even if they are found as missing during reset, the driver is not removing them from its internal list. Modify driver to remove hidden devices from the driver's target device list if they are missing during soft reset.
