WDC_COMPLETE -> ATACMD_COMPLETE
WDC_QUEUED -> ATACMD_QUEUED

77cc762658 Don't assume wdc-specific ATA / ATAPI code should be brought in if atabus 
or atapibus are configured; use a separate wdc_common attribute to indicate
that the shared wdc code is also present.

d24f7ca79e Close a race condition in the datain loop. If we receive another byte between 
reading the FIFO status and reading the interrupt status, we could end up
leaving it in the FIFO.  Force another round through the loop after reading the
interrupt status until the FIFO reads empty again.

Also, there is no point in having the extra loop to wait for the transfer
command to the controller to be acknowledged, because the transfer loop handles
that just fine -- and getting rid of it fixes another race condition.

0fc713f4ea postinstall obsolete minor shared libs support 2004-08-12 02:39:48 +00:00

a5e99ebea6 * Implement obsolete_paths() to obsolete the paths provided on stdin. 
(based on the guts of do_obsolete().
* Implement obsolete_libs() to print a list of obsolete minor/teeny
  shared libraries in the provided directory.
  The implementation supports removing old major libraries similar to
  src/lib/checkoldvers (except this correctly matches more stuff), but
  there's no way to enable that at this time.
* do_rc(): convert to obsolete_paths() to remove old rc.d scripts.
* do_obsolete(): convert to obsolete_paths().  add obsolete_libs() for
  /lib and /usr/lib to remove old minor/teeny shared libraries.
* Clean up the usage.

b2e0a4015a We don't need to implement DRIVE_NOSTREAM here, 'cause we never set 
WDC_CAPABILITY_NOSTREAM.

6e3decbf8a "I was mistaken." 
The memory window is not actually activate in I/O card configurations.  It was
transparently falling back to 16-bit I/O mode.
Implement "memory card" mode correctly, with polling.

6741190fbc Make datain_pio and dataout_pio function pointers in wdc_softc, which can 
be overridden by the backend if desired.  Add experimental code to wdc_pcmcia
to use this in memory-mapped mode, disabled by default.

c8e7b2a367 The memory mode we were trying to use before is a total loss -- we don't get 
any interrupts, and therefore wedge on any access.  However, there is another
memory mode that gives us a memory-mapped data register, which we can use.
Also set the new "DATA1K" flag to tell the wdc backend that we have a large
data area to read from -- this can be used with the region methods.

139ff2a55b Change the behavior when a transfer mode setting is rejected. For PIO, fall 
back to mode 3.  For DMA, fall back to mode 0.  These are the minimums for
ATAPI.  For UDMA, fail.

04a46876e5 Add two helper functions -- wdc_datain_pio() and wdc_dataout_pio() -- which 
encapsulate the logic for the various methods of transferring data.  Use these
throughout.

1a682ebd64 Add 64-bit ABI bootloader (for IP30). Needs a slightly modified toolchain

a23e15bcbe Rather than having a call up from the low-level driver to get the card type, 
instead have a call down from the PCMCIA mid-layer to set it.  Use this from
pcmcia_function_enable().  (Currently the policy is the same, but this would
allow for more flexibility in deciding which mode to use.)

Now it is safe to hold the socket enabled during attach, so do that.  Only
one enable/disable cycle to attach a card now!

8c50dac2a1 Rather than the silly state machine, set whatever higher-level reference 
count there is (for SCSI, adapt_refcnt) to 1 and call the appropriate
"delref" function afterwards to disable the controller.  This is a bit
simpler.

In a couple of cases, just remove the state machine, because it wasn't
really necessary.
