a7c797f063 Disable NCQ for multiport Marvell 88SX61XX SATA controllers. Simultaneous
active I/O to several disks (copying large file on ZFS) causes timeout after
just a few seconds of run. Single port 88SX6111 seems like not affected.

Skip reading transferred bytes count for these controllers. It works for
88SX6111, but 88SX6145 always returns zero there. Haven't tested others,
but better to be safe.

da839e639b Add IDs for HighPoint RocketRAID 64x controllers.
These controllers consist of two Marvell 88SE9128 6Gbps SATA chips and
PLX PCIe bridge. As result, they seem to be agree to work with ahci(4)
as usual HBAs. The only noticed issue is that RAID BIOS disables all
drive caches during boot, though `camcontrol cmd ...` is able to fix that.

Those who wants RAID functionality can still use closed proprietary driver
from HighPoint site.

da6808c111 Make SATA XPT negotiate and enable some additional SATA features, such as:
- device initiated power management (some devices support only this way);
 - Automatic Partial to Slumber Transition (more power saving);
 - DMA auto-activation (expected to slightly improve performance).
More features could be added later, when hardware supports.

83c5d981ac MFp4: Large set of CAM inprovements.
- Unify bus reset/probe sequence. Whenever bus attached at boot or later,
CAM will automatically reset and scan it. It allows to remove duplicate
code from many drivers.
- Any bus, attached before CAM completed it's boot-time initialization,
will equally join to the process, delaying boot if needed.
- New kern.cam.boot_delay loader tunable should help controllers that
are still unable to register their buses in time (such as slow USB/
PCCard/ CardBus devices), by adding one more event to wait on boot.
- To allow synchronization between different CAM levels, concept of
requests priorities was extended. Priorities now split between several
"run levels". Device can be freezed at specified level, allowing higher
priority requests to pass. For example, no payload requests allowed,
until PMP driver enable port. ATA XPT negotiate transfer parameters,
periph driver configure caching and so on.
- Frozen requests are no more counted by request allocation scheduler.
It fixes deadlocks, when frozen low priority payload requests occupying
slots, required by higher levels to manage theit execution.
- Two last changes were holding proper ATA reinitialization and error
recovery implementation. Now it is done: SATA controllers and Port
Multipliers now implement automatic hot-plug and should correctly
recover from timeouts and bus resets.
- Improve SCSI error recovery for devices on buses without automatic sense
reporting, such as ATAPI or USB. For example, it allows CAM to wait, while
CD drive loads disk, instead of immediately return error status.
- Decapitalize diagnostic messages and make them more readable and sensible.
- Teach PMP driver to limit maximum speed on fan-out ports.
- Make boot wait for PMP scan completes, and make rescan more reliable.
- Fix pass driver, to return CCB to user level in case of error.
- Increase number of retries in cd driver, as device may return several UAs.

6268666c1b Add support for SATA part of Marvell 88SE912x controllers to ahci(4).
Limit early revisions from 6Gb/s to 3Gb/s by default, or they negotiate
only 1.5Gbps, when 3Gb/s devices connected.

Add dummy driver for PATA part of these controllers, preventing generic
driver attach them. It causes system freeze when SATA controller used after
PATA was touched.

f343c07f96 While AHCI specification tells that multi-vector MSI doesn't use global IS
register, nVidia chipsets have different oppinion, requiring every interrupt
to be acknowledged there.

While there, add interrupt descriptions in multi-vector MSI mode.

45e1aff18a Clear all ports interrupt status bits in single write. Clearing one by one
causes additional MSIs messages sent if several ports asked for attention
same time. Time window before clearing is not important, as these interrupts
are level triggered by interrupt source.

c8039fc667 MFp4:
- Extend XPT-SIM transfer settings control API. Now it allows to report to
SATA SIM number of tags supported by each device, implement ATA mode and
SATA revision negotiation for both SATA and PATA SIMs.
- Make ahci(4) and siis(4) to use submitted maximum tag number, when
scheduling requests. It allows to support NCQ on devices with lower tags
count then controller supports.
- Make PMP driver to report attached devices connection speeds.
- Implement ATA mode negotiation between user settings, device and
controller capabilities.

9ece9ab1eb Do not attach JMicrons with single PCI function. They are not working as

6bd8779bb9 Change the way in which AHCI+PATA combined controllers, such as JMicron
and Marvell handled. Instead of trying to attach two different drivers to
single device, wrapping each call, make one of them (atajmicron, atamarvell)
attach do device solely, but create child device for AHCI driver,
passing it all required resources. It is quite easy, as none of
resources are shared, except IRQ.

As result, it:
- makes drivers operation more independent and straitforward,
- allows to use new ahci(4) driver with such devices, adding support for
new features, such as PMP and NCQ, same time keeping legacy PATA support,
- will allow to just drop old ataahci driver, when it's time come.

- Limit queue for non-tagged devices by 2 slots for ahci(4) and siis(4).
- Implement quirk matching for ATA devices.
- Move xpt_schedule_dev_sendq() from header to source file.
- Move delayed queue shrinking to the more expected place - element freeing.
- Remove some SCSIsms in ATA.

a1aa38dedf MFp4:
On error, freeze device queue, to allow periph driver to do proper recovery.
Freeze SIM queue only in some cases, when it is needed to protect SIM.

Implement better command timeout detection logic for non-queued commands.
This fixes false positives when command with short timeout waiting for the
long one. For example, when hald tastes CD during burning process.

Read and clear SERR register on interrupt.
