Resending the patch. Addressed the review comments from Tomas Henzl. Current driver allow device scan for all the devices on channel 0 and 1. E.a If we have two single drive raid volumes, we may see prints like below. First two prints are for physical device which are used to form VD. Prints like this creates confusion as it is really not required to scan any hidden physical devices. scsi1 : LSI SAS based MegaRAID driver scsi 1:0:0:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 scsi 1:0:1:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 scsi 1:2:0:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 scsi 1:2:1:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 When slave_alloc called, sdev-type will not be set, so current code will always return "0" in slave_alloc callback. This patch make sure that driver return "-ENXIO" for non-syspd devices. After this patch, we will see prints in syslog only for devices which are exposed. For current example, below print will be available in syslog. scsi1 : LSI SAS based MegaRAID driver scsi 1:2:0:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 scsi 1:2:1:0: Direct-Access LSI MR9361-8i 4.21 PQ: 0 ANSI: 5 Signed-off-by:

In _scsih_probe, propagate the return value from scsi_add_host. In mpt3sas, avoid calling list_del twice if that returns an error, which causes list_del corruption warnings if an error is returned. Tested with blk-mq and scsi-mq patches to properly cleanup from and propagate blk_mq_init_rq_map errors. Signed-off-by:

Up to now, Driver allocates a single contiguous block of memory pool for all reply queues and passes down a single address in the ReplyDescriptorPostQueueAddress field of the IOC Init Request Message to the firmware. When firmware receives this address, it will program each of the Reply Descriptor Post Queue registers, as each reply queue has its own register. Thus the firmware, starting from a base address it determines the starting address of the subsequent reply queues through some simple arithmetic calculations. The size of this contiguous block of memory pool is directly proportional to number of MSI-X vectors and the HBA queue depth. For example higher MSIX vectors requires larger contiguous block of memory pool. But some of the OS kernels are unable to allocate this larger contiguous block of memory pool. So, the proposal is to allocate memory independently for each Reply Queue and pass down all of the addresses to the firmware. Then the firmware will just take each address and program the value into the correct register. When HBAs with older firmware(i.e. without RDPQ capability) is used with this new driver then the max_msix_vectors value would be set to 8 by default. Change set in v1: 1. Declared the _base_get_ioc_facts() functions at the beginning of the mpt3sas_base.c file instead of moving all these functions before mpt3sas_base_map_resources() function a. _base_wait_for_doorbell_int() b. _base_wait_for_doorbell_ack() c. _base_wait_for_doorbell_not_used() d. _base_handshake_req_reply_wait() e. _base_get_ioc_facts() 2. Initially set the consistent DMA mask to 32 bit and then change it to 64 bit mask after allocating RDPQ pools by calling the function _base_change_consistent_dma_mask. This is to ensure that all the upper 32 bits of RDPQ entries's base address to be same. 3. Reduced the redundancy between the RDPQ and non-RDPQ support in these following functions a. _base_release_memory_pools() b. _base_allocate_memory_pools() c. _base_send_ioc_init() d. _base_make_ioc_operational() Signed-off-by: -

Below is the change set in MPI2.5 Rev H specification and 2.00.32 header files 1) Added reserved fields to IO Unit Page 7 for future use. 2) Added optional functionality to IOCInit Request so that the host may specify a separate base address for each Reply Descriptor Post Queue. IOC support for this is indicated using a new IOCCapabilities bit in the IOCFacts Reply. 3) Added Toolbox Console Text Display Tool The host uses the Console Text Display Tool to send a string to IOC's Console using different console types (eg: UART serial terminal or Ethernet terminal). 4) Firmware images can now be signed using an encrypted hash. 5) Added MPI2_SAS_OP_TRANSMIT_PORT_SELECT_SIGNAL 6) Added more details about configuration page restrictions when Host Based Discovery is enabled Enabling host based discovery affects the availability of some configuration pages and events. The SAS Expander, SAS Device, and SAS Enclosure configuration pages are not available from the IOC. The IOC returns an error status to any Configuration Request message attempting to access these pages. The IOC does not send the SAS Discovery Event, the SAS Topology Change List Event, or the SAS Enclosure Device Status Change Event when host based discovery is enabled. 7) Bit 13 of the SAS IO Unit Page 1 ControlFlags field is now obsolete. It was used to enable limiting direct attached SATA maximum link rate to 1.5 Gbps. Signed-off-by:

mpt2sas: Get IOC_FACTS information using handshake protocol only after HBA card gets into READY or Operational state. Driver initialization fails if driver tries to send IOC facts request message when the IOC is in reset or in a fault state. This patch will make sure that 1.Driver to send IOC facts request message only if HBA is in operational or ready state. 2.If IOC is in fault state, a diagnostic reset would be issued. 3.If IOC is in reset state then driver will wait for 10 seconds to exit out of reset state. If the HBA continues to be in reset state, then the HBA wouldn't be claimed by the driver. Signed-off-by:

A type casting error caused the max volume LBA to be truncated from 64 to 32 bits. The virtual LBA would also get truncated to 32 bits in the case of a 16-byte READ/WRITE command. Rewrite entire function to get rid of code duplication and type casts. Use get/put_unaligned wrappers to extract and replace the LBA field in the MPI request CDB. Signed-off-by:

Added driver module parameter max_msix_vectors. Using this module parameter the maximum number of MSI-X vectors could be set.
