UFS clock scaling might start kicking in even before the device is running at the fastest interface speed which is undesirable. This change moves the clock scaling kick start only after the device is detected and running at the fastest interface speed. Signed-off-by:

Currently we are suspending clock scaling during clock gating which doesn't allow us to have clock gating timeout lower than clock scaling polling window. If clock gating timeout is smaller than the clock scaling polling window then we will mostly suspend the clock scaling before clock scaling polling window expires and we might get stuck in same state (scaled down or scaled up) for quite a long time. And for this reason, we have clock gating timeout (150ms) greater than clock scaling polling window (100ms). We would like to have aggressive clock gating timeout even lower than the clock scaling polling window hence this change is decoupling the clock scaling suspend/resume from clock gate/ungate. We will not suspend the clock scaling as part of clock gating instead clock scaling context will schedule scaling suspend work if there are no more pending transfer requests. Signed-off-by:

Whenever some UFS failure occurs the driver prints the UFS registers in order to help with analysis of the failure. However this may not be sufficient in some cases, so having the host controller state as it is represented and managed in the driver will contribute to analysis efforts. Added prints of various fields in the hba struct which may be of interest. Signed-off-by:

UFS driver's load based clock scaling feature scales down the ufs related clocks in order to allow low power modes of chipsets. UniPro 1.6 supports maximum gear up to HS-G3 (High Speed Gear3) and some of the chipsets low power modes may not be allowed in HS-G3 hence this change adds support to scale gear between HS-G3 and HS-G1 based on same existing load based clock scaling logic.

Details printed for each request that is aborted can overload the target as there can be several requests that are aborted at once. This change will print full request details only for the first aborted request since the last link reset, and minimal details for other subsequent requests. Signed-off-by:

On certain error conditions request abort task itself might fail when aborting a request. In such case, subsequent request aborts should skip issuing the abort task as it is expected to fail as well, and device reset handler will be called next. Signed-off-by:

Shifting a dma_addr_t right by 32 bits causes a compile-time warning when that type is only 32 bit wide: drivers/scsi/aacraid/src.c: In function 'aac_src_start_adapter': drivers/scsi/aacraid/src.c:414:29: error: right shift count >= width of type [-Werror=shift-count-overflow] This changes the driver to use the predefined macros consistently, including one correct but open-coded upper_32_bits() instance. Fixes: d1ef4da8 ("scsi: aacraid: added support for init_struct_8") Fixes: 423400e6 ("scsi: aacraid: Include HBA direct interface") Signed-off-by:

aac_fib_send can return -ve error returns and hence rcode should be signed. Currently the rcode >= 0 check is always true and -ve errors are not being checked. Thanks to Dan Carpenter for spotting my original broken fix to this issue. Signed-off-by:

Instead define the timeout behavior purely based on the host_template eh_timed_out method and wire up the existing transport implementations in the host templates. This also clears up the confusion that the transport template method overrides the host template one, so some drivers have to re-override the transport template one. Signed-off-by:

EH_NOT_HANDLED is the default case if no eh_timed_out method is provided, so there is no need to supply it. Signed-off-by:

These days we can specify an eh_timed_out handler in the host_template, so don't have a transport_template definition just for it. [mkp: fixed typo] Signed-off-by:

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.
