ata: add/use ata_taskfile::{error|status} fields

2022-02-20T00:06:05Z

Add the explicit error and status register fields to 'struct ata_taskfile' using the anonymous *union*s ('struct ide_taskfile' had that for ages!) and update the libata taskfile code accordingly. There should be no object code changes resulting from that... Signed-off-by: Sergey Shtylyov Signed-off-by: Damien Le Moal

ata: ahci: Drop pointless VPRINTK() calls and convert the remaining ones

2022-01-05T10:33:01Z

Drop pointless VPRINTK() calls for entering and existing interrupt routines and convert the remaining calls to dev_dbg(). Signed-off-by: Hannes Reinecke Signed-off-by: Damien Le Moal

ata: libata: add reset tracepoints

2022-01-04T11:00:57Z

To follow the flow of control we should be using tracepoints, as they will tie in with the actual I/O flow and deliver a better overview about what it happening. This patch adds tracepoints for hard reset, soft reset, and postreset and adds them in the libata-eh control flow. With that we can drop the reset DPRINTK calls in the various drivers.

ata: libata: Add ata_port_classify() helper

2022-01-04T11:00:45Z

Add an ata_port_classify() helper to print out the results from the device classification and remove the debugging statements from ata_dev_classify(). Signed-off-by: Hannes Reinecke Signed-off-by: Damien Le Moal

ata: libata: remove pointless debugging messages

2022-01-04T11:00:35Z

Debugging messages in pci init functions or sg setup are pretty much pointless, as the workflow pretty much decides what happened. So drop them. Signed-off-by: Hannes Reinecke Signed-off-by: Damien Le Moal

ata: libahci: Adjust behavior when StorageD3Enable _DSD is set

2021-11-18T05:34:25Z

The StorageD3Enable _DSD is used for the vendor to indicate that the disk should be opted into or out of a different behavior based upon the platform design. For AMD's Renoir and Green Sardine platforms it's important that any attached SATA storage has transitioned into DevSlp when s2idle is used. If the disk is left in active/partial/slumber, then the system is not able to resume properly. When the StorageD3Enable _DSD is detected, check the system is using s2idle and DevSlp is enabled and if so explicitly wait long enough for the disk to enter DevSlp.

scsi: ata: Switch to attribute groups

2021-10-17T01:45:52Z

struct device supports attribute groups directly but does not support struct device_attribute directly. Hence switch to attribute groups.

libata: Introduce ncq_prio_supported sysfs sttribute

2021-08-18T13:19:39Z

Currently, the only way a user can determine if a SATA device supports NCQ priority is to try to enable the use of this feature using the ncq_prio_enable sysfs device attribute. If enabling the feature fails, it is because the device does not support NCQ priority. Otherwise, the feature is enabled and success indicates that the device supports NCQ priority. Improve this odd interface by introducing the read-only ncq_prio_supported sysfs device attribute to indicate if a SATA device supports NCQ priority. The value of this attribute reflects the status of device flag ATA_DFLAG_NCQ_PRIO, which is set only for devices supporting NCQ priority. Add this new sysfs attribute to the device attributes group of libahci and libata-sata.

ata: ahci: Disable SXS for Hisilicon Kunpeng920

2021-03-31T14:25:15Z

On Hisilicon Kunpeng920, ESP is set to 1 by default for all ports of SATA controller. In some scenarios, some ports are not external SATA ports, and it cause disks connected to these ports to be identified as removable disks. So disable the SXS capability on the software side to prevent users from mistakenly considering non-removable disks as removable disks and performing related operations.
