 1.58  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.57  21-Oct-2019  christos follow the channel locking protocol during probe (like the other drivers)
 1.56  09-Dec-2018  jdolecek use pci_intr_establish_xname() everywhere
 1.55  20-Oct-2017  jdolecek branches: 1.55.2; 1.55.4;
move ata_queue_alloc(1) and ata_queue_free() calls to ata_channel_init()
and ata_channel_destroy() respectively, to make attachment code simpler,
and to make it easier to spot special queue manipulation like cmdide(4)

 1.54  07-Oct-2017  jdolecek Merge support for SATA NCQ (Native Command Queueing) from jdolecek-ncq branch

ATA subsystem was changed to support several outstanding commands, and use
NCQ xfers if supported by both the controller and the disk, including NCQ
error recovery. Set NCQ high priority for BPRIO_TIMECRITICAL xfers
if supported. Added FUA support.

Done some work towards MP-safe, all ATA code tsleep()/wakeup() replaced
by condvars, and switched most code from spl* to mutexes (separate
wd(4) and ata channel lock).

Introduced new option WD_CHAOS_MONKEY to facilitate testing of error
handling, fixed several uncovered issues. Also fixed several problems
with kernel dump to wd(4) disk.

Tested with ahcisata(4), mvsata(4), siisata(4), piixide(4) on amd64,
with and without port multiplier, both disk and ATAPI devices; other
drivers and archs mechanically adjusted and compile-tested. NCQ is
supported for ahcisata(4) and siisata(4) for any controller, for
mvsata(4) only Gen IIe ones for now. Also enabled ATAPI support in
mvsata(4).

Thanks to Matt Thomas for initial ATA infrastructure patch, and
Jonathan A.Kollasch for siisata(4) NCQ changes and general testing.

Also fixes PR kern/43169 (wd(4)); and PR kern/11811, PR kern/47041,
PR kern/51979 (kernel dump)
 1.53  23-Aug-2016  msaitoh branches: 1.53.4;
Remove PCI_PRODUCT_CMDTECH_240's entry because CMDTECH_AAR_1210SA has
the same ID.
 1.52  29-Mar-2014  christos branches: 1.52.4; 1.52.6; 1.52.12;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.
 1.51  07-Oct-2013  jakllsch Use the universal pciide_detach() for detach function of all remaining
pciide-core drivers, except pciide at pnpbios which isn't actually PCI.
 1.50  15-Sep-2013  martin Comment out unused variables
 1.49  27-Oct-2012  chs branches: 1.49.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.48  31-Jul-2012  bouyer branches: 1.48.2;
Apply back changes that were reverted on Jul 24 and Jul 26 (general ata/wdc
cleanup and SATA PMP support), now that I'm back to fix the fallouts.
 1.47  26-Jul-2012  jakllsch Revert, with intention of restoring in a less invasive way, the SATA Port
Multiplier code.

ok christos@
 1.46  24-Jul-2012  jakllsch Revert dsl@'s changes of Sun, 15 Jul 2012 10:55:35 +0000 and
Sun, 15 Jul 2012 10:56:50 +0000, excepting the kernel version bump.
First step in reverting regressions to ata(4) subsystem during the addition of
port multiplier support.
 1.45  15-Jul-2012  dsl Some namespace protection (and add greppablity).
Prefix the DRIVE_ and DRIVET_ constants from atavar.h with ATA_.
Don't use an enum for drive_type - you don't know how big it will be.
Move driver_type to avoid implicit structure padding (esp on arm).
This change is purely lexical and mechanical.

Update to 6.99.9 - this wasn't done when the SATA PMP changes
were made - I'm sure they warranted a bump.
 1.44  02-Jul-2012  bouyer Add sata Port MultiPlier (PMP) support to the ata bus layer,
as described in
http://mail-index.netbsd.org/tech-kern/2012/06/23/msg013442.html
PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()

propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).

Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
when SATA cable move was needed

Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
Probably a bug. I use a temporary variable. I have not tested this
change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
Probably a bug. Use a local pci_attach_args. I have not tested
this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
caller's pci_attach_args. Probably a bug. Make a local copy of the
caller's pci_attach_args and modify the copy. I have not tested
this change.

While I'm here, make pci_mapreg_submap() static.

With these changes in place, I have tested the compilation of these

 1.22  21-Aug-2004  thorpej atastart() (called only at splbio(), and from interrupts) can change
drive_flags, to make sure all drive_flags manipulations are done at
splbio().
 1.21  20-Aug-2004  thorpej Move most of wdc_softc into a new atac_softc structure that contains
info common to all types of ATA controllers.
 1.20  19-Aug-2004  thorpej - Add and use a CHAN_TO_WDC() macro to get the wdc_softc from an
ata_channel.
- Add and use a CHAN_TO_WDC_REGS() macro to get the wdc_regs from an
ata_channel.
- Add and use a CHAN_TO_PCIIDE() macro to get the pciide_softc from an
ata_channel.
- Add and use a CHAN_TO_PCHAN() macro to get the pciide_channel from an
ata_channel. (This one just hides a cast, and is really just for
consistency with the others.)
 1.19  14-Aug-2004  thorpej - Split the register handles out of struct wdc_channel into a separate
wdc_regs structure, and array of which (indexed per channel) is pointed
to by struct wdc_softc.
- Move the resulting wdc_channel structure to atavar.h and rename it to
ata_channel. Rename the corresponding flags.
- Add a "ch_ndrive" member to struct ata_channel, which indicates the
maximum number of drives that can be present on the channel. For now,
this is always 2. Add an ATA_MAXDRIVES constant that places an upper
limit on this value, also currently 2.
 1.18  13-Aug-2004  thorpej Don't bother with bits that tell of the presence of optional callbacks;
just check the function pointers for NULL.
 1.17  19-Jul-2004  msaitoh branches: 1.17.2;
Add Adaptec AAR-1210SA serial ATA RAID.
RAID is not supported by this driver.
 1.16  23-Jun-2004  briggs When the Silicon Image 3112 retries a PCI memory read command, it
may retry it as a memory read multiple command under some circumstances.
This can totally confuse some PCI controllers, so ensure that it
will never do this by making sure that the Read Threshold (FIFO
Read Request Control) field of the FIFO Valid Byte Count and Control
registers for both channels (BA5 offset 0x40 and 0x44) are set to
be at least as large as the cacheline size register (the unit of
measure for these registers is 32 bytes).
 1.15  28-May-2004  thorpej Use the common sata_speed() routine.
 1.14  25-May-2004  thorpej Add the notion of "shadow registers" to the wdc driver. These shadow
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers. Right now, the two
shadows are:

- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)

Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.

Partially from Jordan Rhody @ Wasabi Systems, Inc.
 1.13  07-May-2004  sekiya Add support for Silicon Image 3512 chip to satalink driver -- treat it as
a 3112 variant (without RAID support), which does the right thing with the
controller on my K8NNXP.
 1.12  07-Jan-2004  thorpej branches: 1.12.2;
Initialize some importantant members of the drive info structure. (I have
no idea how this worked for me before, but I swear that it did...)

kern/24015.
 1.11  03-Jan-2004  thorpej More wdc_channel structure member namespace cleanup:
- channel -> ch_channel
- wdc -> ch_wdc
 1.10  03-Jan-2004  thorpej Rename "struct channel_softc" to "struct wdc_channel".
 1.9  01-Jan-2004  thorpej Rename:
- wdc_xfer to ata_xfer
- channel_queue to ata_queue
and move them to <dev/ata/atavar.h> so they can be used by non-wdc ATA
controllers. Clean up the member names of these structures while at it.
 1.8  31-Dec-2003  martin Include <dev/ata/atareg.h>, so that WDSD_IBM is defined.
 1.7  30-Dec-2003  thorpej Move the drive probing code out of atabusconfig() and into a new
wdc_drvprobe() function. wdc_drvprobe() is used if the controller
does not specify a custom one prior to calling wdcattach(). The
WDC_CAPABILITY_DRVPROBE bit is gone.
 1.6  20-Dec-2003  thorpej Fix a typo.
 1.5  20-Dec-2003  thorpej Add support for the Silicon Image 3114 SATALink 4-port SATA controller.
 1.4  19-Dec-2003  thorpej Use a register map to find the offsets of various per-channel
registers in the BA5 space.
 1.3  15-Dec-2003  thorpej Remove the notice that was in cmdide.c before SATALink support was split
out. All of the code in this file was written by me.
 1.2  15-Dec-2003  thorpej Use the SControl and SStatus registers to query the SATA PHY for
device detection.
 1.1  13-Dec-2003  thorpej Split out the Silicon Image SATALink support into its own driver,
"satalink".
