Currently there is a logging level option provided for each of our

Only when this option is enabled will the functions which display the

In this patch, increased the number of MSIX vector support for SAS3 C0 HBAs to
up-to 96.

Following are changes that are done in this patch

1. This feature is enabled only for SAS3 C0 and higher revision cards and also
only when reply post free queue count is greater than 8.

2. To support this feature 12 SupplementalReplyPostHostIndex system interfaces
are used. MSI-X index numbered from 0 to 7 use the first
SupplementalReplyPostHostIndex system interface to update its corresponding
ReplyPostHostIndex values, MSI-X index numbered from 8 to 15 will use the
second SupplementalReplyPostHostIndex system interface and so on. These 12
SuppementalReplyPostHostIndex system interfaces address are saved in the array
replyPostRegisterIndex[].

3. As each SupplementalReplyPostHostIndex register supports 8 MSI-X
vectors. So MSIxIndex field in these register must contain a value between 0
and 7.

4. After processing the reply descriptors from a reply post free queues then
update the new reply post host index value in ReplyPostHostIndex field and
(msix_index mod 8) value in MSIxIndex field of SupplementalReplyPostHostIndex
register. The Address of this SupplementalReplyPostHostIndex register is
retrived from (msix_index/8)th entry of replyPostRegisterIndex[] array.

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()

[SCSI] mpt2sas: Fix for Driver oops, when loading driver with max_queue_depth command line option to a very small value

If the specified max_queue_depth setting is less than the
expected number of internal commands, then driver will calculate
the queue depth size to a negitive number. This negitive number
is actually a very large number because variable is unsigned
16bit integer. So, the driver will ask for a very large amount of
memory for message frames and resulting into oops as memory
allocation routines will not able to handle such a large request.

So, in order to limit this kind of oops, The driver need to set
the max_queue_depth to a scsi mid layer's can_queue value. Then
the overall message frames required for IO is minimum of either
(max_queue_depth plus internal commands) or the IOC global
credits.
