Move a check for the drive type to the right place. This bug would cause
ATA drives to not be detected when the PATA (or emulated PATA) bus is shared
with an ATAPI device.
Should fix the problem reported by various peoples.
Thanks to Onno van der Linden and vanoven@free.fr for pointing out the
code in error.

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.

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.

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.

Revision 1.114 / (download) - annotate - [select for diffs], Mon Jul 2 18:15:48 2012 UTC (10 months, 2 weeks ago) by bouyer
Branch: MAIN
Changes since 1.113: +7 -7 lines
Diff to previous 1.113 (colored)

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

Add a bustype_async_event_xfer_mode() callback to scsipi_bustype (which can
be NULL), so that transport-specific details of transfer mode setting/printing
can be handled more easily.
Move scsipi_async_event_xfer_mode() and scsipi_print_xfer_mode() to
scsi_base.c and split in parallel scsi and FC/SAS parts.
size of struct scsipi_bustype has changed, welcome to 6.99.5

	sys/dev/scsipi/atapi_wdc.c: revision 1.104
Fix for atapi devices that have 32 bit databusses selected. The devices
won't error out but will return garbage data. Implemented by generalising
the odd-check for PIO selection to check for 4 byte alignment in offset and
size.
Note that this check could be relaxed by checking if the ATAPI/ide bus
width is 16 for the device but its unknown to me if that information is
available here.

Fix for atapi devices that have 32 bit databusses selected. The devices
won't error out but will return garbage data. Implemented by generalising
the odd-check for PIO selection to check for 4 byte alignment in offset and
size.

Note that this check could be relaxed by checking if the ATAPI/ide bus
width is 16 for the device but its unknown to me if that information is
available here.

In gcc4 structures are differently aligned compared to gcc3. Lots of
structures can thus be misaligned for DMA when declared on stack.

The current atapi code accepts the misaligned dma's only screw's them up.
This small patch disables DMA for the rare transactions that are
misaligned. Note that all bulk-transfers are aligned due to page sizes.

See PR kern/34689

Add PIOBM (busmastering transfer using ATA PIO mode) support.
The PIOBM is used by only one driver (will be added later,
stay tuned) and intruduce an attribute "ata_piobm" so that
it will be conditionally compiled in.
The "ata_dma" (busmastering transfer using ATA DMA mode) and
"ata_udma" (busmastering transfer using ATA Ultra DMA mode)
attributes are also added for consistency, but unused for now.

to use this in memory-mapped mode, disabled by default.

Change the behavior when a transfer mode setting is rejected.  For PIO, fall

ATAPI.  For UDMA, fail.

Add
struct ata_xfer *active_xfer
to ata_queue. Now the active xfer isn't the head of the queue any more,
this makes a few things easier (this will also help for tagged queuing
support).
Remove the WDCF_ACTIVE flag, test active_xfer != NULL instead.
clean up wdc_free_xfer() and kill_xfer().
Clean up wdc_reset_channel(), and make it issue a ATAPI_SOFT_RESET if the
active command is ATAPI.
In wdc_atapi_get_params(), use AT_WAIT | AT_POLL for ATAPI_SOFT_RESET,
so that we'll use tsleep() instead of delay().
In wdc_atapi_start(), call wdc_dmawait() at the right place.

Implement asynchronous channel reset.
Use this to reset the channel before doing a dump, instead of the hack in
  wdc_exec_xfer() based on C_POLL. This hack was causing problems on
  controllers with a shared queue, because we now can have C_POLL set during
  concurent channels probes (problem found and analysed on sparc64 by
  Martin Husemann).
This should even make core dumps marginally more reliable on ATA drives.

There are some cards that map the ATA control and IDE DMA registers
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.

To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.

	bus_space_write_4(tag, handle, offset, value)

becomes

	bus_space_write_4(tag, handles[offset], 0, value)

Reviewed by Manuel Bouyer. Tested on wdc_isa, wdc_pcmcia, viaide, piixide (i386)
and on cmdide (sparc64).

Make the ATA mid-layer appears as atabus, as proposed in
http://mail-index.netbsd.org/tech-kern/2003/09/25/0006.html
This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.

Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Main changes to the scsipi code itself:
- add a scsipi_channel->type to allow umass to attach to both atapibus and
  scsibus. Will die when IDE is converted from ata_atapi_attach to
  scsipi_channel/scsipi_adapter
- Add a chan_defquirks to scsipi_channel so that adapters can pass a default
  set of quirks to be set for each device attached
- add adapt_getgeom and adapt_accesschk callbacks

- DMA code cleanup: pciide_dma_finish() doesn't stop/unload the current DMA op
  if an IRQ was not detected, unless the force flag was given. Use this to
  detect if the IRQ was for us (closer to shared IRQ for controllers which
  don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
  Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
  (wdc_*), so that it's possible to attach an atapibus to something else
  than a wdc/pciide (Hi Lennart :).
  Overload struct scsi_adapter with struct atapi_adapter, defined
  as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
  to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
  Move atapi_softc to atapiconf.h so that it can be used by the underlying
  controller code (e.g. atapi_wdc.c).
  Add an atapi-specific callback *atapi_probedev(), which probe a drive
  in a controller-specific way, allocate the sc_link and fills in the
  ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
  to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
  It should now be possible to use a common ata/atapi routine to set the
  drive's modes (will do later).

- Add some debug printf (WDCPROBE) in _wdcreset_wait(), I've needed these
  2 times in the past
- Set up timeout per xfer instead of per interrupt. This helps with
  PIO transfer (we would call timeout()/untimout() several times for a
  transfer).
- If we missed an interrupt for a PIO transfer, reset and restart it
  immedialy, don't try to recover and continue. If we missed an interrupt we
  may have lost a read/write cycle on the IDE bus. If this happens 1) we
  corrupt data and 2) we enter an interrupt loop at the end of the xfer, as
  the drive has some more data to read/write, but the host thinks the xfer is
  done.
This last change fix the (or at last some of the) 'lookup after lost interrupt'
some peoples have been experiencing.

Add patch from Manuel Bouyer -- his mail message said:

By code inspection I found 2 bugs in the ATAPI code, one may be the cause
of your problem: A counter is not reset when issuing the request_sense
command. This is c_skip, the counter used to track the offset in the data
buffer when a data tranfer needs multiple phases. The effect of this is that
the sense data transfered may be stored outside the sense buffer (sense buffer
+ some, potentially several KB, offset). This can only occur in PIO mode,
DMA is not affected.
This doesn't occur in "normal" use because when reading a data CD, either
the sense is issued for a non-data command (in which case c_skip stays to
0), or an error occured and no data has been transfered, and c_skip is still 0.
I can't see a case where a data READ/WRITE could cause a sense tranfer without
error.

The second problem is that b_resid can be set to a false value (resulting of
the sense tranfer and not the data transfer). Again this is not a problem with
usual data tranfers because both values ends up being 0 when no error occurs.

If setting to pio mode < 3 fails, try to set pio mode 3 before returning
EIO. The spec says ATAPI devices should support "PIO 3 or better".
They are supposed to support less as well. Setting the device to a highter
mode than the controller shoul'nt be a problem, and this is likely what
happens with legaty ISA controllers.

Fix a long-standing bug with the ACAP_* flags:
- the cap field is a u_int8_t, so none of the defined flags would fit in.
  Looks like nobody had a drive using 16 bytes commands.
- the ACAP_DRQ_* flags are all wrong. Just remove them and use the definitions
  from ata/atareg.h, there's no need to duplicate theses. The effect of this
  was that we were always polling for the command phase, even for drives
  with interrupt DRQ. This didn't break until the code was changed to support
  shared interrupts.

Should fix the lookup problems or 'boot hangs' reported by some users, and

This fixes a bug where CDs withot the DRQ_INTR capability would not busy-wait

garbage-collect some old code from wdcintr() which has been ifdef'd out

in wdc_softc: access the per-channel data via a pointer array instead of
an array of fixed-sized channel_softc elements. This way IDE controllers
which more than 1 channel (pciide) can extend the channel data easily
for private needs.
To avoid the double dereference at runtime, change the argument of
wdcstart() to the channel data pointer instead of the array index.

In atapi_wdc.c, issue a 'REQUEST SENSE' command when appropriate.
Return XS_SENSE when the full sense info has been retrieved, or
XS_SHORTSENSE if only the sense key was available (from the error register)
Make atapi_interpret_sense() deal with this, and call scsipi_interpret_sense()
for XS_SENSE. (XXX sd_interpret_sense() and the ioctl code needs to be made
aware of XS_SHORTSENSE too ! sense hanlding for these is now less broken for
devices that support 'REQUEST SENSE')
All the ATAPI devices I have access to seems to honnor the SENSE_REQUEST
command, but I suspect some ATAPI devices will not (althouh it's mandatory).
The code should be able to deal with this, but is untested ...

- always call config_found() from wdcattach(), instead of printing our own
  the "not configured" message ourselve. When no atapibus is configured,
  use a fake ata_atapi_attach, else call wdc_atapibus_attach(). This way we
  don't have to include the whole atapi support in an ata-only config.
- the dma_* function pointers take a 'int flags' as last argument, instead
  of an 'int read'. The 2 valid flags are: WDC_DMA_READ (to select read/write)
  and WDC_DMA_POLL, to signal interrupt-less mode (for core dumps).
- Reworked wdcprobe() so look more like the old one. A status of 0xff is
  interpreted as "no drive" (freebsd does this); this this speed up
  the probe for non-IDE machines (a reset timeout has been bumped to 31s,
  to match the specs). The probe set ups the drive flags to either ATA or
  ATAPI (depend on register signature) or OLD (if register signature don't
  match, but a working drive appears to be there). Later the ATA code
  will look at the OLD flag to decide wether there is no drive, or an old
  (ST506) one if WDC_IDENTIFY fails.
- For known PCI chips, don't use the wdcprobe() heuristic to find wether
  a channel is enabled/disabled; use the chip's specific registers for this.
- Clear the command queue when we have a polled command. This allows dumps to
  work even if a command was being handled by the controller at panic time.
- Increase the number of available DMA segments by one, as user requests may
  not be aligned on a page boundary.
