gwr 50ecbc1c84 Rename cs_pclk_div16 to cs_brg_clk to clarify the fact that the
Baud Rate Generator (BRG) clock is not necessarily PCLK/16.

thorpej dedd4cceab Fix typo, noticed by Curt Sampson <curt@portal.ca>. 1996-05-09 21:15:47 +00:00
thorpej 69351e2be6 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.

thorpej 0584bf86a8 Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

gwr 035d12359e Remove some hacks that "went around" the linesw[] operations. 1996-04-26 18:36:54 +00:00
christos 78403e6c0c Add a hardware dependent initialization function lehwinit() 1996-04-22 02:25:54 +00:00
cgd d7d306aeb7 change LANCE copy & zero functions' names to start with amd7990_, and
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).

cgd 83f9bdc359 update for the fact that config_found() and config_rootfound() now
return pointers.  (Check vs. NULL, rather than just boolean tests.)

thorpej 3cd14f7597 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

chuck 9f330ed6e0 Fix two bugs reported by Don Koch <aardvark@poirot.krl.com> (PR#2168).
(the xd bugs also apply to the xy driver...)
 [1] check return value from malloc() for NULL before trying to bzero it.
 [2] use "=" rather than "|=" when writing to CSR (otherwise you may
        ACK something you don't mean to!).

chuck 718ac5d246 [import changes from sparc port]
- moved disk_busy() call from xdstrategy() to xdc_startbuf()
        [prevents disk_unbusy panic when disk is loaded (if no
        free IOPBs, xdstrategy() would queue the buffer for pickup
        by xdcintr() but xdcintr() would never call disk_busy().
        xdc_startbuf() is a better place since all bufs are routed
        through here]   problem detected by girish@dworkin.wustl.edu,
        diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
        XDC_FREE() [don't want to access a data structure that was just put
        on a free list]

gwr f2e57c6dc8 Eliminate remaining direct references to the z8530 chip

chuck 8f339409b7 sync with sparc:
- move disk_attach() to before reading the disk label as per Jason.
	otherwise we are reading into an unallocated buffer (oops!)
1996-01-13 03:50:05 +00:00
thorpej 5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

DMA works!  Interrupts work!  Disconnect/reselect works!
To be paranoid, leave that all disabled for now...

gwr b3a6cbaeb0 New from Chuck Cranor: drivers for SMD disks!

gwr 93d0f65970 New SCSI driver for the NCR5380, by David Jones.
Does DMA with interrupts.  Much faster than our old
driver which did only PIO transfers. (Thanks David!)
Could be used on the amiga, and probably others...
