Like sas_printk() did previously, SAS_DPRINTK() offers little value now that libsas logs already have the "sas" prefix through pr_fmt(fmt). 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(). Suggested-by:

The printk wrapper sas_printk() adds little value now that libsas logs already have the "sas" prefix through pr_fmt(fmt), so just use pr_notice() directly. In addition, strings which span multiple lines are reunited. Originally-from: Joe Perches <joe@perches.com> Signed-off-by:

Currently the time of SAS SSP connection is 1ms, which means the link connection will fail if no IO response after this period. For some disks handling large IO (such as 512k), 1ms is not enough, so change it to 5ms. Signed-off-by:

In function hisi_sas_task_prep(), we check asd_sas_port, but in function hisi_sas_task_exec(), we already refer to asd_sas_port by using function dev_to_hisi_hba() implicitly. So to avoid this possible invalid dereference, relocate the check to function hisi_sas_task_prep(). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

UFS host supplies the reference clock to UFS device and UFS device specification allows host to provide one of the 4 frequencies (19.2 MHz, 26 MHz, 38.4 MHz, 52 MHz) for reference clock. Host should set the device reference clock frequency setting in the device based on what frequency it is supplying to UFS device. Signed-off-by:

Add trunking support to the driver. Trunking is found on more recent asics. In general, trunking appears as a single "port" to the driver and overall behavior doesn't differ. Link speed is reported as an aggregate value, while link speed control is done on a per-physical link basis with all links in the trunk symmetrical. Some commands returning port information are updated to additionally provide trunking information. And new ACQEs are generated to report physical link events relative to the trunk. This patch contains the following modifications: - Added link speed settings of 128GB and 256GB. - Added handling of trunk-related ACQEs, mainly logging and trapping of physical link statuses. - Added additional bsg interface to query trunk state by applications. - Augment link_state sysfs attribtute to display trunk link status Signed-off-by:
