Was uncommented in the original driver, and I'm too lazy to figure out the conversion. Signed-off-by:

The advansys_reset() function is actually a host reset, not a bus reset. And there is no need to have a 'last_reset' value; the same value exists in struct Scsi_Host. Signed-off-by:

The fusion HBAs don't really use the instance template like the other variants, as it branches off at a much higher level. So instead of trying to squeeze megasas_fire_cmd_fusion into the wrong calling convention call it locally with argument data types that match what is passed.

Converting structure fields in place is always a bad idea, and in this case by moving it into the only caller we also only have to do a single byte swap as most fields of this structure are never used. Signed-off-by:

This patch will add support for Single Server High Availability(SSHA) cluster support. Here is the short decsription of changes done to add support for SSHA- 1) Host will send system's Unique ID based on DMI_PRODUCT_UUID to firmware. 2) Toggle the devhandle in LDIO path for Remote LDs.

megaraid_sas driver will use block layer provided tag for indexing internal MPT frames to get any unique MPT frame tied with tag. Each IO request submitted from SCSI mid layer will get associated MPT frame from MPT framepool (retrieved and return back using spinlock inside megaraid_sas driver's submission/completion call back). Getting MPT frame from MPT Frame pool is very expensive operation because of associated spin lock operation (spinlock overhead increase on multi NUMA node). This type of locking in driver is very expensive call considering each IO request need - Acquire and Release of the same lock. With this support, in IO path driver will directly provide the unique command index(which is based on block layer tag) and will get the MPT frame tied to the tag and this way driver can get rid off lock, which synchronizes the access to MPT frame pool while fetching and returning MPT frame from the pool. This support in driver provides siginificant performance improvement(on multi NUMA node system)on latest upstream with SCSI.MQ as well as on existing linux distributions. Here is the data for test executed at Avago- - IO Tool- FIO - 4 Socket SMC server. (4 NUMA node server) - 12 SSDs in JBOD mode . - 4K Rand READ, QD=32 - SCSI MQ x86_64 (Latest Upstream kernel) - upto 300% Performance Improvement. If IOs are running on single Node, perfromance gain is less, but as soon as increase number of nodes, performance improvement is significant. IOs running on all 4 NUMA nodes, with this patch applied IOPs observed was 1170K vs 344K IOPs seen without this patch. Logically, there are two parts of this patch- 1) Block layer tag support 2) changes in calling convention of return_cmd. part 2 will revert the changes done by patch- 90dc9d98 megaraid_sas : MFI MPT linked list corruption fix because changes done in part 1 has fixed the problem of MFI MPT linked list corruption. part 2 is very much dependent on part 1, so we decided to have single patch for these two logical changes.

This patch will add separate function for refiring MFI commands in Fusion adapters's OCR code. Signed-off-by:

Sumit.Saxena@avagotech.com authored
This patch will create separate functions for- 1) setting up IRQs for MSI-x interrupts 2) setting up IRQs for legacy interrupts 3) freeing up IRQs. and enable interrupts after adapter's initialization. The reason behind initialising adapter earlier is: by that time firmware is operational and can send interrupts, so better to use interrupt based interface to send internal DCMD to firmware instead of using polling method, since MFI frames' pool size is reduced and polling method does not free up MFI frame for fusion adapters, so sending more DCMDs with polled method may cause MFI frames's pool go out of frames and end up failing DCMD.
