Moved the READ and WRITE switch cases to the top. Added a default case to the switch case and replaced duplicate scsi result value with a macro. The idea is that since most of scsi commands we care about performance wise are read or write, we need to process them first. Internally the compiler (GCC) converts a switch case into either a jump table or a bunch of if else conditions, so placing the often used read, write cases at the top is an effort in optimization.

Due existence of loop in the IO path our HBA will receive heavy IOs and also as driver is not updating the Reply Post Host Index frequently, So there will be a high chance that our Firmware unable to find any free entry in the Reply Post Descriptor Queue (i.e. Queue overflow occurs) and can observe 0x2100 firmware fault. So to fix this, we have defined a thresh hold value. After continuously processing this thresh hold number of reply descriptors driver will update the Reply Descriptor Host Index so that this thresh hold number of reply descriptors entries will be freed and these entries will be available for firmware and we won't observe this Firmware fault. We have defined this threshold value as 1/3rd of the hba queue depth. Signed-off-by:

The atari_scsi driver should not access Falcon DMA chip registers unless it has acquired exclusive access to that chip. If the driver doesn't have exclusive access then there's no need for a DMA reset as there are no scsi commands in progress. Signed-off-by:

The NCR5380 wrapper drivers don't export symbols or declarations and don't actually need separate header files. Most of these header files were removed already; only sun3_scsi.h and g_NCR5380.h remain. Move the remaining definitions to the corresponding .c files to improve readability and proximity. The #defines which influence the #included core driver are no longer mixed up with unrelated #defines and #includes. Signed-off-by:

Remove dead code inside #if 0 conditionals. Remove the #ifdef __KERNEL__ test, since NCR5380.h has no definitions that relate to userspace code. Remove two redundant macro definitions which were overlooked in commit e9db3198 ("sun3_scsi: Adopt NCR5380.c core driver"). Signed-off-by:

The DIFFERENTIAL and PARITY option macros are unused: no supported hardware uses differential signalling and the core driver never implemented parity checking. These options just waste space in the host info string. While we are here, fix a typo in the NCR5380_info() kernel-doc comment. Signed-off-by:

There is a potential probe issue in how we trigger the hw initialisation. Although we use 1s timer to delay hw initialisation, there is still a potential that sas_register_ha() is not be finished before we start the PHY init from hw->hw_init(). To avoid this issue, initialise the hw after sas_register_ha() in the same probe context. Note: it is not necessary to use 1s timer now (modified v2 hw only). Signed-off-by:

Xiang Chen authored
The v2 SAS controller needs more time to detect channel idle and send setup link request than SATA disk does, so it is difficult for the SAS controller to setup an STP link. Therefore it may cause some IO timeouts. We need to periodically configure the SAS controller so it doesn't receive STP setup requests from SATA disks for a while, so IO can be sent during this period. Signed-off-by:

When processing an AFU asynchronous interrupt, if the action results in an operation that requires off level processing (a link reset for example), the worker thread is scheduled. In the meantime a reset event (i.e.: EEH) could unmap the AFU to recover. This results in an Oops when the worker thread tries to access the AFU mapping. [c000000f17e03b90] d000000007cd5978 cxlflash_worker_thread+0x268/0x550 [c000000f17e03c40] c00000000011883c process_one_work+0x1dc/0x680 [c000000f17e03ce0] c000000000118e80 worker_thread+0x1a0/0x520 [c000000f17e03d80] c000000000126174 kthread+0xf4/0x100 [c000000f17e03e30] c00000000000a47c ret_from_kernel_thread+0x5c/0xe0 In an effort to avoid this, a mapcount was introduced in commit b45cdbaf ("cxlflash: Resolve oops in wait_port_offline") but due to the race condition described above, this solution is incomplete. In order to fully resolve this problem and to simplify things, this commit removes the mapcount solution. Instead, the scheduled worker thread is cancelled after interrupts have been disabled and prior to the mapping being freed.
