2023-12-05scsi: mpi3mr: Support for preallocation of SGL BSG data buffers part-1Chandrakanth patil
The driver now supports SGLs for BSG data transfer. Upon loading, the driver pre-allocates SGLs in chunks of 8k, results in a total of 256 * 8k, equal to 2MB. These pre-allocated SGLs are reserved for handling BSG commands and are deallocated during driver unload.

2023-02-21scsi: mpi3mr: Use number of bits to manage bitmap sizesShin'ichiro Kawasaki
To allocate bitmaps, the mpi3mr driver calculates sizes of bitmaps using byte as unit. However, bitmap helper functions assume that bitmaps are allocated using unsigned long as unit. This gap causes memory access beyond the bitmap sizes and results in "BUG: KASAN: slab-out-of-bounds". The BUG was observed at firmware download to eHBA-9600. Call trace indicated that the out-of-bounds access happened in find_first_zero_bit() called from mpi3mr_send_event_ack() for miroc->evtack_cmds_bitmap. To fix the BUG, do not use bytes to manage bitmap sizes. Instead, use number of bits, and call bitmap helper functions which take number of bits as arguments. For memory allocation, call bitmap_zalloc() instead of kzalloc() and krealloc(). For memory free, call bitmap_free() instead of kfree(). For zero clear, call bitmap_clear() instead of memset(). Remove three fields for bitmap byte sizes in struct scmd_priv which are no longer required. Replace the field dev_handle_bitmap_sz with dev_handle_bitmap_bits to keep number of bits of removepend_bitmap across resize.

2022-05-02scsi: mpi3mr: Add support for NVMe passthroughSumit Saxena
Add support for management applications to send an MPI3 Encapsulated NVMe passthru command to the NVMe devices attached to an Avenger controller. Since the NVMe drives are exposed as SCSI devices by the controller, the standard NVMe applications cannot be used to interact with the drives and the command sets supported are also limited by the controller firmware. Special handling is required for MPI3 Encapsulated NVMe passthru commands for PRP/SGL setup in the commands.

2022-05-02scsi: mpi3mr: Add support for PEL commandsSumit Saxena
Implement driver support for management applications to enable persistent event log (PEL) notifications. Upon receipt of events, the driver will increment a sysfs variable named event_counter. The management application will poll for event_counter value changes and signal the application about events.
