itohy c72407329e Treat receiver overrun of MFP (clear the error). 
Although the keyboard hardware seems to be designed to avoid
overrun, the errors sometimes occur.

itohy 61363bb1c6 Fix the problem where pressing a key at 
scsibus0: waiting 2 seconds for devices to settle...
message during boot crashes the system.
This is because ite_filter() is called before init(8) opens the console.

minoura a8580db029 Revert 1.18 change. 
Hopefully this is a temporary fix; something might be missing in
the SCSI negotiation.

minoura dd8c46b8be Explicitly include opt_m680x0.h. 2000-04-18 21:06:06 +00:00
thorpej 4044b5a41c Use separate callouts for motor-on and motor-off. Fixes a condition 
where the floppy driver would wedge because a motor-on timeout would
be cancelled by another I/O operation cancelling a motor-off timeout.

From enami tsugutomo <enami@sm.sony.co.jp>.

minoura 87bc025f49 Move par under intio. 2000-03-27 15:53:04 +00:00
minoura f23d278c1d Make this compile (typo in callout change). 2000-03-27 15:49:34 +00:00
thorpej 7b918b4088 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.

minoura 077b93be1a According to Takeshi Nakayama <tn@catvmics.ne.jp>, 
POW_ALARMSW seems always 1 on some models (at least XVI).

thorpej fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple 
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.

thorpej dc59bc1db3 Update for sys/buf.h/disksort_*() changes. 2000-01-21 23:39:55 +00:00
minoura 2a71e2c15e Minor cleanups & corrections. 2000-01-16 14:20:54 +00:00
itohy cf055ef630 Change the implementation of ms(4) polling to use timeout(9) software 
interrupt in order to eliminate glitches on MPU interrupt levels.
I don't know whether this is a good solution, but it does work.
 2000-01-14 08:22:42 +00:00
itohy 169af5c51b Add a dummy read just after enabling receiver interrupt. 
If the receiver already has datum, no further arrival of
data is possible and no interrupts will occur.
This change fixes problem that pressing key during boot
may sometimes disable the keyboard.

Remove unreferenced variable "in" in kbdcngetc().

thorpej e6c88a7686 Update for SCSIPI changes. 1999-09-30 22:59:52 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

thorpej 3ebbe095e0 Change the pmap_extract() interface to: 
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

"memlock" resource limit to uvm_mmap().  Update all calls accordingly.

thorpej f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input() 
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
