3413bcbb7aSyt  *
3513bcbb7aSyt  * At the moment, the ahci driver only implements suspend/resume to
3613bcbb7aSyt  * support Suspend to RAM on X86 feature. Device power management isn't
3713bcbb7aSyt  * implemented, link power management is disabled, and hot plug isn't
3813bcbb7aSyt  * allowed during the period from suspend to resume.
3913bcbb7aSyt  *
4013bcbb7aSyt  * For s/r support, the ahci driver only need to implement DDI_SUSPEND
4113bcbb7aSyt  * and DDI_RESUME entries, and don't need to take care of new requests
4213bcbb7aSyt  * sent down after suspend because the target driver (sd) has already
4313bcbb7aSyt  * handled these conditions, and blocked these requests. For the detailed
4413bcbb7aSyt  * information, please check with sdopen, sdclose and sdioctl routines.

47fd6d41c5SRobert Mustacchi  * Enclosure Management Support
48fd6d41c5SRobert Mustacchi  * ----------------------------
49fd6d41c5SRobert Mustacchi  *
50fd6d41c5SRobert Mustacchi  * The ahci driver has basic support for AHCI Enclosure Management (EM)
51fd6d41c5SRobert Mustacchi  * services. The AHCI specification provides an area in the primary ahci BAR for
52fd6d41c5SRobert Mustacchi  * posting data to send out to the enclosure management and provides a register
53fd6d41c5SRobert Mustacchi  * that provides both information and control about this. While the
54fd6d41c5SRobert Mustacchi  * specification allows for multiple forms of enclosure management, the only
55fd6d41c5SRobert Mustacchi  * supported, and commonly found form, is the AHCI specified LED format. The LED
56fd6d41c5SRobert Mustacchi  * format is often implemented as a one-way communication mechanism. Software
57fd6d41c5SRobert Mustacchi  * can write out what it cares about into the aforementioned data buffer and
58fd6d41c5SRobert Mustacchi  * then we wait for the transmission to be sent.
59fd6d41c5SRobert Mustacchi  *
60fd6d41c5SRobert Mustacchi  * This has some drawbacks. It means that we cannot know whether or not it has
61fd6d41c5SRobert Mustacchi  * succeeded. This means we cannot ask hardware what it thinks the LEDs are
62fd6d41c5SRobert Mustacchi  * set to. There's also the added unfortunate reality that firmware on the
63fd6d41c5SRobert Mustacchi  * microcontroller driving this will often not show the LEDs if no drive is
64fd6d41c5SRobert Mustacchi  * present and that actions taken may potentially cause this to get out of sync
65fd6d41c5SRobert Mustacchi  * with what we expect it to be. For example, the specification does not
66fd6d41c5SRobert Mustacchi  * describe what should happen if a drive is removed from the enclosure while
67fd6d41c5SRobert Mustacchi  * this is set and what should happen when it returns. We can only infer that it
68fd6d41c5SRobert Mustacchi  * should be the same.
69fd6d41c5SRobert Mustacchi  *
70fd6d41c5SRobert Mustacchi  * Because only a single command can be sent at any time and we don't want to
71fd6d41c5SRobert Mustacchi  * interfere with controller I/O, we create a taskq dedicated to this that has a
72fd6d41c5SRobert Mustacchi  * single thread. Both resets (which occur on attach and resume) and normal
73fd6d41c5SRobert Mustacchi  * changes to the LED state will be driven through this taskq. Because the taskq
74fd6d41c5SRobert Mustacchi  * has a single thread, this guarantees serial processing.
75fd6d41c5SRobert Mustacchi  *
76fd6d41c5SRobert Mustacchi  * Each userland-submitted task (basically not resets) has a reference counted
77fd6d41c5SRobert Mustacchi  * task structure. This allows the thread that called it to be cancelled and
78fd6d41c5SRobert Mustacchi  * have the system clean itself up. The user thread in ioctl blocks on a CV that
79fd6d41c5SRobert Mustacchi  * can receive signals as it waits for completion.  Note, there is no guarantee
80fd6d41c5SRobert Mustacchi  * provided by the kernel that the first thread to enter the kernel will be the
81fd6d41c5SRobert Mustacchi  * first one to change state.
