drochner 1bf98e790e one more case: don't use ISACF_* constants internally 2004-09-01 21:30:25 +00:00
reinoud 943622e723 Delay initialisation of shadow registers. Tested on a Shark. 2004-08-25 13:06:16 +00:00
thorpej 9cc521a148 Move most of wdc_softc into a new atac_softc structure that contains
info common to all types of ATA controllers.

thorpej 2926431abf Use ANSI function decls and "static". 2004-08-19 23:30:09 +00:00
thorpej 4b51cecfc2 - 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.

drochner 7ba5b8cd09 adapt for changed essattach() signature 2004-08-04 18:55:06 +00:00
thorpej 2ecdd552dc 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.

thorpej a963286f8d More wdc_channel structure member namespace cleanup:

thorpej 5bd80d8373 Rename "struct channel_softc" to "struct wdc_channel". 2004-01-03 01:50:52 +00:00
thorpej 527c829fa0 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.

fvdl 6242a54566 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).

bouyer 99d6009c2a 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.

mycroft eefae40298 Hide the use of config_interrupts() in one place. 2003-09-25 19:29:48 +00:00
mycroft d40837608f 1) Use config_interrupts() to attach IDE and ATAPI drives. This eliminates
most polling.
2) Clean up some goofiness in pciide -- get rid of the whole "candisable" path
   (it's gratuitous) and simplify the code by calling pciide_map_compat_intr(),
   *_set_modes() and wdc_print_modes() from central locations.
3) Add a register writability and register ghost test to eliminate phantom
   drives more quickly.

jdolecek 372e5956ef Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.
