bouyer 0016706a70 Clean up revision stuff for the sis. Suggested by Chris Cappuccio. 2000-01-18 13:58:07 +00:00
bouyer 9156026f0f From chris@openbsd.org:
"Don't enable UDMA modes for revisions of SiS 5513 < 0xd0
The only revisions I know which don't actually support UDMA are 0x09 and below..
But the only revision I know which does support UDMA is 0xd0 (and presumably
above that)"

pciide_mapregs_compat(). From OpenBSD.

bouyer 8e49b58de0 Add support for Intel 810 chipset (ICH/ICH0).
While I'm there merge back piix_channel_map into piix_chip_map.
1999-08-30 12:49:21 +00:00
bouyer 52068f73ce Add support for the Promise Ultra/33 and /66 pci IDE controller. In addition to
chip-dependant code this required the following changes:
- Instead of attaching the device in a generic way with some chip-dependant
  routines, use a chip-dependant attach routine with some common code
  factored out. The code is marginally bigger, but this allows the CMD64x
  flag hack to go away.
- For chips that report per-channel 'irq triggered', test this before calling
  wdcintr() for the native-pci irq case (compat intr can't be shared),
  as wdcintr() has no good way to know if a irq was for it or not, and
  ends up with irq loss. XXX for chips that don't have this feature irq sharing
  will not work properly !
- add my copyrigth notice (could have been done some time ago I think :)

There are still some issues to be solved with the Promise controller and
ATAPI devices.
Many thanks to Paul Newhouse for shipping me 2 Ultra/33 boards for doing this
work.

bouyer cc46db1ba6 For the PIIX, make sure the PIO_mode and DMA_mode get reset to the values used
by the controller for all drives.
1999-05-27 09:45:50 +00:00
bouyer 9893727873 Fix the way we compute the mode to use: for multiword DMA, the used mode was
2 less than the one we could really use, so for multiword DMA mode 0 or 1,
the driver tried to use DMA mode 255 or 254 (0 - 2 with a u_int8_t).

bouyer 71036465a5 In cy693_setup_channel(), setup timings for IOR too (they were left to 0,
which is a way too higth timing for some devices). Thanks to Ken Wellsch
for trying the multiple debug kernels until the problem was located.

bouyer 2ccd5cde74 Correctly compute PIO/DMA mode for sis and acer chips when the drive support
a DMA mode with higther capabilities than PIO mode.

bouyer 5888b4354e channel_map is called before setup_chip, so whe need to enable the channel
status bits in acer_channel_map().

bouyer ca240ca7b5 Support for Acerlab M5229 IDE controller. Thanks to Thilo Manske for testing
the code, and to Takahiro Kambe who run several tests and finally found the
bug by himself :)
1999-02-02 16:13:59 +00:00
bouyer f1addbd3fd Defer mapping of pci interrupt to pciide_mapregs_native(). This way,
the native interrupt shouldn't be mapped if a channel is in native mode,
but disabled.

bouyer e39a5bdc53 Now that vtophy() is no longuer used, re-enable WDCDEBUG, with
wdcdebug_pciide_mask = 0 (so that one can easily patch this variable and give
me more informations :)
1998-12-03 17:27:57 +00:00
bouyer 2b28c858d8 add a udma_mode field to wdc_softc, and use it the same way dma_mode is used
(higthest ultra-dma mode supported). There may be a higther ultra-dma mode
defined ...

bouyer 7d87d6a5f6 Use correct register when disabling the second channel. 1998-12-03 13:50:38 +00:00
bouyer 8ef785add8 Restore changes from revision 1.17:
"If a channel has no drives, do *not* unmap its I/O regions.
 It's not really safe to use them for anything else, and in legacy mode it
 will just cause us to probe the channel again as an ISA device."
1998-12-03 13:30:00 +00:00
bouyer 1af63c0605 Correct a few bogons in the SiS chip initialisation. 1998-12-03 13:25:44 +00:00
bouyer 09408781c9 Ouh ! Correct the 8-bit PCI registers reading/writing functions: need to
multiply the register offset by 8.
1998-12-03 13:24:11 +00:00
bouyer 45675ab14b - change drive_flags from u_int8_t to u_int16_t
- keep the modes supported by the drive in struct ata_drive_datas (will be
  later used for downgrading the DMA/PIO mode on error)
- use config flags to force/disable PIO/DMA/UDMA modes
- For the CMD PCI0643/6 setup DMA mode to DMA Read multiple.

drochner 5888c5ef44 a small optimization for the compat interrupt handling, possible after
channel_softc is within pciide_channel
1998-11-24 19:54:20 +00:00
drochner 9effbbe436 some restructuring, more or less to get support for weird IDE controllers,
eg the Cypress ISA bridge:
-put channel mapping into the chip specific part, unify with
 channel_probe() into channel_map()
-use pointer to channel data as function call argument wherever possible
 instead of the channel number
-allow the "compat" channel number to differ from the per-controller
 channel number - for mapping and interrupt functions
-add support for SiS5598 and Cypress 82C693 chips
Mostly done by Manuel, I only contributed to the first 2 items.

bouyer 56107b8e10 Force PCI_COMMAND_MASTER_ENABLE if DMA has been setup properly. The BIOS is
supposed to do it but who knows ...
1998-11-12 15:05:29 +00:00
bouyer 1e71e76d6c - clearify the boot messages (features supported vs features used). Thanks to
Havard Eidnes for his complains about this :)
- fix some typo in comments
- hoppefully better detection of drives reporting bogus PIO modes.
1998-11-11 19:38:27 +00:00
bouyer 432a301fc6 Support for the CMD PCI064{3,6}. Tested on a 0646 with a
"wd0: PIO mode 4, DMA mode 2, UDMA mode 2" device.
1998-11-09 09:21:09 +00:00
bouyer 31dec5ddc5 Add config flags for pciide: 0x001 forces the use of DMA when the driver
don't know how to set the controller's modes.
1998-10-22 15:11:39 +00:00
bouyer 1456b01d77 Fix for Apollo DMA mode (not UDMA): DMA mode = PIO mode - 2, not PIO mode + 2 ! 1998-10-20 18:47:45 +00:00
bouyer c90c4b829b Add support for the second flavour of the VIA IDE chip (which has UDMA).
Don't claim DMA support if we don't have explicit support for this chip.
They're to may way to loose when trying to use DMA without configuring the
controller and disks.
1998-10-19 12:24:33 +00:00
bouyer da5d0a6f17 pciide.c: don't define WDCDEBUG, so it compiles on alpha. Correct a bogon
in the printing of DMA mode (piix3/4 only)
others: set the debug_mask to 0, so that debug messages are turned off by
default but can be easily turned on.
Reset drive_flags to 0 for unconfigured devices, so that they are ignored
later. For configured devices, reset state to 0 after probe/attach.

bouyer 19fddaeeb5 Merge bouyer-ide 1998-10-12 16:09:10 +00:00
drochner a8d0a43ffa 2 changes to pciide_probe_wdc() (used in compatibility mode to check
if i drive is responding):
-if the reset succeeds, check some registers to make sure there is really
 a drive (and not a chipset which echoes back the last written value)
-explicitely select the master before trying to read the master's status

thorpej ea3a1d9c44 Nuke __BROKEN_INDIRECT_CONFIG. 1998-06-08 06:55:54 +00:00
cgd b9eaff9db8 when considering attaching compatibility-mode channels, try a quick reset
and see if anything responds.  if nothing (that's attributable to the
PCI IDE controller) responds, then that channel either has no devices on
it or has been disabled (via a non-standard mechanism) by the BIOS.  If nothing
responds, don't map the compat.-mode interrupt or attach the wdc to that
channel, because the BIOS is likely to assign that IRQ to a different PCI
device.  If that happens, the kernel will panic because that device will
try to map the IRQ level-triggered, but the compat interrupt will have been
mapped edge-triggered.  (One possible way around this is to map the compat
interrupt edge-triggered, but it's not clear reading the spec that this
is correct or desirable.)
1998-03-12 23:34:29 +00:00
cgd ff06be8ce0 reorganize mapping/attachment of wdc channels so that it'll be easier to
insert a check to see whether a channel appears to be enabled.  Shouldn't
be necessary, according to the spec, but some PC chipsets allow individual
compatibility channels to be disabled.  "I hate PCs."
1998-03-06 19:13:19 +00:00
cgd f528463b81 despite the spec, some people map the bus master IDE registers into
memory space.  Note that in a comment, but don't try to fix it (for now).
