Subject: [PATCHSET 2/4] libata: implement ata_link, take 5
Newsgroups: gmane.linux.ide
Date: Monday 16th July 2007 09:34:38 UTC (over 10 years ago)
Hello, all.

This is the fifth take of implement ata_link patchset.  This patchset
contains 16 patches which can be categorized as follows.

#01-02: prep
#03-04: implement ata_link
#05-08: make libata deal with link instead of port
#09-11: misc link stuff (link init, reset_tries, ata_link_abort())
#12-16: 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.

* ata_link_init_spd_limit() renamed to ata_link_init_spd()

This patchset is against

  libata-dev#upstream (d79eb6de54f180dc83b488b20747f0097fde3dea)
  + [1] misc-updates patchset

Thanks.
