Subject: [PATCHSET] implement ata_link, take 3
Newsgroups: gmane.linux.ide
Date: Sunday 15th October 2006 22:54:39 UTC (over 10 years ago)
Hello, all.

This is the third take of implement ata_link patchset.  This patchset
contains 18 patches which can be categorized as follows.

#01-03: prep
#04-05: implement ata_link
#06-09: make libata deal with link instead of port
#10-12: misc link stuff (link init, reset_tries, ata_link_abort())
#13-19: 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 fully host attached
devices including qc management and EH/hotplug.  This patchset makes
libata ready to handle PM links.

Changes from the last take[L] are.

* updated to fit new #upstream
* __dev1 trick removed

This patchset is against

  upstream (da54f5fe54c7d75e2db7d17961fb36a8c28a8501)
  + [1] hp-poll patchset, take #5
  + [2] vt8251-ahci patchset, take #2

Thanks.
