scsi: aacraid: Reorder Adapter status check

2017-03-12T05:44:12+00:00

commit c421530bf848604e97d0785a03b3fe2c62775083 upstream. The driver currently checks the SELF_TEST_FAILED first and then KERNEL_PANIC next. Under error conditions(boot code failure) both SELF_TEST_FAILED and KERNEL_PANIC can be set at the same time. The driver has the capability to reset the controller on an KERNEL_PANIC, but not on SELF_TEST_FAILED. Fixed by first checking KERNEL_PANIC and then the others.

scsi: aacraid: mark aac_src_select_comm() static

We get 1 warning when building kernel with W=1: drivers/scsi/aacraid/src.c:616:5: warning: no previous prototype for 'aac_src_select_comm' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. so this patch marks this function with 'static'.

aacraid: Log firmware AIF messages

2016-04-29T23:08:24+00:00

Firmware AIF messages about cache loss and data recovery are being missed by the driver since currently they are not captured but rather let go. This patch to capture those messages and log them for the user. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

aacraid: Fix RRQ overload

2016-02-24T02:27:02+00:00

The driver utilizes an array of atomic variables to keep track of IO submissions to each vector. To submit an IO multiple threads iterate through the array to find a vector which has empty slots to send an IO. The reading and updating of the variable is not atomic, causing race conditions when a thread uses a full vector to submit an IO. Fixed by mapping each FIB to a vector, the submission path then uses said vector to submit IO thereby removing the possibly of a race condition.The vector assignment is started from 1 since vector 0 is reserved for the use of AIF management FIBS.If the number of MSIx vectors is 1 (MSI or INTx mode) then all the fibs are allocated to vector 0.
