| | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that, in this particular case, I replaced "Missed the backend's Closing state -- fallthrough" with "fall through - Missed the backend's Closing state", which contains the "fall through" annotation at the beginnig of the code comment, which is what GCC is expecting to find.

Both fabric_ops.get_fabric_name() and fabric_ops.name are user-facing, with the former being used for PR/ALUA state and the latter for ConfigFS (config/target/$name), so we unfortunately need to keep both strings around for now.

So it can be dropped. However, after reviewing some logs in libsas, it is noticed that debug level is too low in many instances. So this change drops SAS_DPRINTK() and revises some logs to a more appropriate level. However many stay at debug level, although some are significantly promoted. We add -DDEBUG for compilation so that we keep the debug messages by default, as before. All the pre-existing checkpatch errors for spanning messages across multiple lines are also fixed. Finally, all other references to printk() [apart from special formatting in sas_ata.c] are removed and replaced with appropriate pr_xxx().

| | * scsi: hisi_sas: Add support for interrupt coalescing for v3 hwXiang Chen2018-11-152-0/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If INT_COAL_EN is enabled, configure time and count of interrupt coalescing. Then if CQ collects count of CQ entries in time, it will report the interrupt. Or if CQ doesn't collect enough CQ entries in time, it will report the interrupt at timeout. As all the registers are not supported to be changed dynamically, we need to config those register between disable and enable PHYs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CQ_INT_CONVERGE_EN is enabled, the interrupts of all the 16 CQ queues will be reported by CQ0. So we need to change the process of CQ tasklet for this situation. Signed-off-by: Xiang Chen <chenxiang66@hisilicon.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all the three HBA (v1/v2/v3 HW) share the same host attributes. To support each HBA having separate attributes in future, create per-HBA attributes.

| | | | | | | | | | | | | | | | | | | | | | | | The wd719x driver currently uses a mix of the legacy PCI DMA and the generic DMA APIs. Switch it over to the generic DMA API entirely. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the SCB onto the scsi command allocation and use dma streaming mappings for it only when in use. This avoid possibly calling dma_alloc_coherent under a lock or even in irq context, while also making the code simpler. Thanks to Ondrej Zary for testing and various bug fixes.
