itojun f564201ae9 sync with ata driver change (dma_start args). 2000-04-02 02:07:52 +00:00
thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

thorpej 3bc7ce8d31 Cast bus_size_t to u_long for printing. 2000-02-08 18:40:51 +00:00
thorpej 52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.

bouyer ba2e85e711 32 bits I/O ocasionally fails on some hardware, so the test succeed but
the kernel can get a 'protection fault trap' later. Enable the 32 bits I/O
test conditionally on a config flag, disabled by default (problem
reported by kurt.schreiner@uni-mainz.de).

bouyer 503de51fdd Fix probe code for IDE devices:
- Don't rely on ATA signature: some ide controllers seems to not transmit it
  properly (SIMIDE on arm32 machines). Instead, when we guess a drive is here
  after reset, just mark it as ATA and OLD is it's not ATAPI.
- at attach time, use IDENTIFY to eliminate ghost from the probe. If the
  drive had the old flag and IDENTIFY failed, issue a WDCC_RECAL command
  to detect a pre-ATA disk. If IDENTIFY succeded, remove the OLD flag,
  it's obviously not a pre-ATA disk.
- add a new controller flag, WDC_CAPABILITY_PREATA, used to shorcut parts
  of the probe (not necessary, but makes the probe/attach faster). This is
  only set by the ISA front-end, all other controllers supported can't have
  pre-ATA drives attached.
The mechanism used are more or less the same as before, they have just been
reordered. Should solve port-arm32/7324 (waiting for feedback).

bouyer 47ab212504 Rename pio_mode, etc ... to PIO_cap, etc ... for consistency with the
ata_drive_datas struct. Suggested by Soren S. Jorvan.

drochner 3e38051bc5 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.

cgd 85687409e1 don't forget to set dma_arg, when using DMA functions. also, minor
spacing bogon cleanup.  Pointed out by Kazuki Sakamoto in PR 5157.

drochner 6f8773dd64 I'm not responsible for this address window splitting hack, but I fix it
anyway.

cgd 9d3aef5632 Put each of two labels one line to early. That could cause a panic,
if the wdc space couldn't be mapped.  Pointed out by fvdl@netbsd.org.

cgd aaede4d8d8 Various cleanups and bug fixes to the wdc/wd code:
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
  even if there are no drives attached, and so that it works
  properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
  ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
  completely true, but mostly so; they at least work on arm32 and
  i386).
* Various other minor fixups and cleanups, some of which were pointed
  out by Kazuki Sakamoto.
