8a5da00284 Minor conditionalization of XXX_MPLOCK on PEND_INTS. 1997-08-09 22:52:59 +00:00
Steve Passe
6354231eaa Added 'lock' instruction before 3 places that update ipending. 
This may or may not fix the "high IO freezes SMP kernel" problem.

c0ecffb96b Modify the scheduling policy to take into account disk I/O waits 
as chargeable CPU usage.  This should mitigate the problem of processes
doing disk I/O hogging the CPU.  Various users have reported the
problem, and test code shows that the problem should now be gone.

63fe995cb4 Teach both disk drivers how to cope with a hardware watchdog 
while dumping core.. I'm tired of getting 1/2 of a core-dump

conditional on -DHW_WDOG for now
this will migrate to 2.2 as that's where I need it.

5230cfd2f4 Use up 4 precious bytes to give the kernel a hook to

a1af9248eb Yeah I'm back hacking syscons !! 
Add support for MODEX 320x240x256color with "unchained" adressing, giving
access to all 256K on all VGA's, those with that much memory that is :)

Also make sysmouse use the right resolution in graphics modes.

fdfbeb33ae Add ID's for 5 VLSI chips. They're not very friendly, so this info was 
found by taking my HP800CT apart, perusing HPs (Very good!) service
manual and inference from a bad gif file I found in Finland.
Sigh...  But it's a nice machine :-)

750f6aad7b Support interface names up to 15 characters in length. In order to 
accommodate the expanded name, the ICMP types bitmap has been
reduced from 256 bits to 32.

A recompile of kernel and user level ipfw is required.

To be merged into 2.2 after a brief period in -current.

6d529e4303 Remove two features that have been reported to cause problems with 
certain variants of the NCR chip from FE_CACHE_SET: FE_CLSE (enable
cache-line size register) and FE_ERMP (enable read-multiple). They
will be re-enabled, if a fix for the underlying problem (a restriction
in the memory to memory move logic of some chips) has been implemented.
