thorpej 46f4277564 WDCDEBUG -> ATADEBUG. 2004-08-13 04:10:49 +00:00
thorpej ab20886f7b Don't bother with bits that tell of the presence of optional callbacks; 
just check the function pointers for NULL.

bouyer 574dd00e11 If acknowledge "bogus" interrupts (that is, interrupts that have happened 
according to the controller-dependant registers while wdc was not waiting for
an interrupt). A reset can generate spurious interrupts (or even a flow of
spurious interrupts on the promise) that needs to be properly acknowledged.

thorpej a963286f8d More wdc_channel structure member namespace cleanup: 
- channel -> ch_channel
- wdc -> ch_wdc
 2004-01-03 22:56:52 +00:00
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.

thorpej 98f7d12017 Split out the Silicon Image SATALink support into its own driver, 
"satalink".

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).

wiz ee1b406595 Spell address with two d's. Inspired by similar changes in OpenBSD, 
originating from Jonathon Gray and forwarded by jmc@openbsd.

simonb b6abb6ab1d Remove some assigned-to but otherwise unused variables. 2003-10-30 01:58:17 +00:00
mycroft a480189bf8 Remove IDE_PCI_CLASS_OVERRIDE -- it wasn't actually used anywhere. In lieu of 
it, add a class/subclass check to drivers that do not (appear) to have a unique
ID for the IDE controller.  This includes aceride, cypide and optiide.

thorpej 36e9866d7b Cosmetic changes: 
- Use static to unexport symbols that don't need to be exported.
- ANSI'ify.
- Some whitespace nits.

bouyer 9d02ccdbdf Split pciide in per-chip family driver, as proposed in 
http://mail-index.netbsd.org/tech-kern/2003/09/25/0007.html
We now have:
acardide*       at pci? dev ? function ?        # Acard IDE controllers
aceride*        at pci? dev ? function ?        # Acer Lab IDE controllers
cmdide*         at pci? dev ? function ?        # CMD tech IDE controllers
cypide*         at pci? dev ? function ?        # Cypress IDE controllers
hptide*         at pci? dev ? function ?        # Triones/HighPoint IDE controllers
optiide*        at pci? dev ? function ?        # Opti IDE controllers
piixide*        at pci? dev ? function ?        # Intel IDE controllers
pdcide*         at pci? dev ? function ?        # Promise IDE controllers
siside*         at pci? dev ? function ?        # SiS IDE controllers
slide*          at pci? dev ? function ?        # Symphony Labs IDE controllers
viaide*         at pci? dev ? function ?        # VIA/AMD/Nvidia IDE controllers
pciide*         at pci? dev ? function ? flags 0x0000   # GENERIC pciide driver

serverworks driver not commited yet; there are still copyright issues about
it.
