ad 87f451b1a0 This isn't relevant any more. 2001-08-04 16:55:07 +00:00
ad 03e46dc80b Some changes from OpenBSD, and some of my own: 
- More SCSI port defs.
- Nuke vtophys().
- Release resources in iop_init() upon failure.
- Don't use a message wrapper when initalising the outbound FIFO.
- A couple of field size/endian fixes.
- Just use iop_post() when we don't need special handling.
- IM_DISCARD is now pointless, since we don't queue at the driver level.
- Map data transfers from/to userspace directly.
- A few comment and stylistic changes.

enami 97ceb61316 MII access routines for ASIX AX88190. 2001-08-04 11:38:57 +00:00
chs 6bc422a7ee use pmap_k* in pagemove() (ie. for buffer cache pages) 
and in vmapbuf() and vunmapbuf() (since there's no VAC on this platform).

chs ea127ad258 use pmap_k* in pagemove(), ie. for buffer cache pages. 
in vunmapbuf(), call pmap_kremove() explicitly since uvm_km_free_wakeup()
will soon no longer do it for us.

chs f6a81a1ac7 remove the uncached idle-loop page zeroing. 
(to be replaced by a version that uses the cache...)
 2001-08-04 04:26:48 +00:00
chs 873e926c7b remove remaining spl calls, they're not needed. 
remove some checks for impossible conditions.
in pmap_enter(), only call pmap_remove() to remove an existing mapping
if there actually is an existing mapping.

in pmap_remove_pv(), don't flush the MIPS1 cache when removing the last mapping.
this was added in rev 1.97, to avoid stale data being left in the cache
when the page is zeroed bypassing the cache in pmap_zero_page_uncached().
we've since found that bypassing the cache for idle-loop page zeroing
doesn't work very well anyway, so we don't do that anymore.
so now we can remove the extra cache-flush.
remove pmap_zero_page_uncached() while I'm thinking of it.

various other cleanup.

chs 843823c7c5 rewrite set_segmap_allctx() in assembly.

bouyer 7c292e3d22 - kill the carrier detect code. It's not usefull any more and can give 
false informations on a loaded ethernet segement.
- convert to bus_dma(9) (better late than never :)
- add proper le32toh/htole32 so that it works on big-endian system (tested
  on macppc).
Close PR kern/10327.

thorpej 08b77f43f0 Deal with the SSE FPU save format. 2001-08-02 22:04:57 +00:00
thorpej f0449fd933 - Rename cpu_use_fxsave to i386_use_fxsave. 
- If we detect SSE/SSE2 support in the CPU, enable SSE exceptions
  and set i386_has_{sse,sse2} as appropriate.
- Expose i386_use_fxsave and i386_has_{sse,sse2} through sysctl
