Hello, all.
This is the seventh take of implement ata_link patchset. This
patchset contains 14 patches which can be categorized as follows.
#01-02: implement ata_link
#03-06: make libata deal with link instead of port
#07-09: misc link stuff (link init, reset_tries, ata_link_abort())
#10-14: add ap->pmp_link[] and update libata to deal with multiple
links
ata_link abstracts PHY and sits between ata_port and ata_device. The
following attributes are moved to ata_link from ata_port.
- active command state (active_tag, sactive)
- [hw_]sata_spd_limit
- eh_info and eh_context
- device array
With above and a few extra fields, a link can handle attached devices
including qc management and EH/hotplug. This patchset makes libata
ready to handle PMP links.
Changes from the last take[L] are.
* adapted to the current upstream
* drivers/scsi/libsas/sas_ata.c updated
This patchset is against
libata-dev#upstream (5ee30f070f467aaae027f03ef6772128a887b1a3)
Thanks.
