e330356ffb Change got_status/modem_status assignment per Bruce suggestion, 
because inb clears modem status port.

1e22c1b2c7 Localize previous changes (removing dma_reset) 
only for SB card, it seems that it breaks GUS at least.

046b1c1ed5 Tracker "swapping" problem finally solved, 
all (expect one) dma_reset calls commented out.

ac322158f5 Eliminated the "physstrat" wart and merged it into kern_physio.c. This 
patch also fixes a bug which causes a kernel VM leak.

6b4ac811ca New routine "pmap_kenter", designed to take advantage of the special 
case of the kernel pmap.

827f6dbf32 1) Better fix for false carrier detect on bidir port 
2) ttyclose moved after comhardclose, because clears t_state
3) slpx(s) moved after l_open to prevent undetected carrier down

dad5c5fe90 ifdef KERNEL the pmap_kextract inline function; ps is unhappy otherwise.

ed7fcbd079 From John Dyson: performance improvements to the new bounce buffer 
code.
 1994-03-24 23:12:48 +00:00

c9ffdca0a7 1) After discussion with Hannu, returning speed changed back. 
Real problem fixed by my previous fix for SB 2.x
2) get_time function slightly modified to minimize possible
overflowing.

6378ff1e87 Enabled bounce buffers by default. This should be done via a probe for 
the specific controller type, so this change is temporary.

5d8d655374 For SB 2.x speed was reduced to 22050; 
I already fix this bug in previous driver version,
but new driver update breaks my changes!

f73cefd412 1) GET_TIME function completely broken 
it returns time in microseconds instead of HZ
(feel difference!)
2) change GET_TIME type to unsigned long in all places to prevent overflow
 1994-03-23 19:27:52 +00:00

83bd7ca8b0 1) Change dtrwait 300 to 3 * hz (to be more kosher) 
2) Protect sioclose by spltty()

wrong places removed now.

308352e4d4 Changed the raw partition number from 3 to 0. This change lets us use 
/dev/mcd0a instead of /dev/mcd0d. This is more conforming to the /dev/cd0a
for the SCSI cdrom drives. It breaks the convention d the whole drive.
But the question is, do we really need partitions on cdrom drives ?

16a6a70817 Makefile.i386: 
put vers.o at the end of the loader line. We are simply jumping in the
moment into the first location of the text segment in 386bsd. So the
linking order is very important :-). With the addition of the const
types in newvers.sh we jumped into them. I have experimented with an
entry point specification, but was unsuccessfull. Someone else should
look at this.
devices.i386:
files.i386:
Added entries for a Sony cdrom driver.

67a850fc67 Increase default DTR wait time up to 3 secs. 
Also hardw. specs says 2.5 secs is enough, many modems needs
at least 3 secs.

29360eb099 Changed dynamic stack grow code to grow by "SGROWSIZ" amount. Initially 
allocate SGROWSIZ amount of stack. Also set vm_ssize to the initial
stack VM size. Increased DFLSSIZ stack rlimit default to 8MB.

93555dc983 Two fixes from John Dyson to fix hangs and panics when using ctrl-T: 
1) tty.c: gather all the info about the processes before calling ttyprintf
	(which may block).
2) syscons.c: handle asynchronous output properly (data structures may
	be corrupted otherwise).

65f120b86a Remove ttyfree from sioclose 
Example:
Application use port cua01
Getty open ttyd1 (allocates rawq,outq,etc) and waits while application
done
Application quits, sioclose issued, ttyfree issued (getty calls revoke)
Getty awakes and goes to panic into initrb (NULL rawq)

b3e3ac9f89 Increased maximum protection for data segment to VM_PROT_ALL because 
some (lisp) programs try to execute code out of it.

ee3794ce7d Catch the divide by zero bug earlier. If the drive give back 
a zero cylinder and/or head count, set them and the sector count
to some fictious values. The same already happens if the request
sense is unsuccessfull.

not yet speak to this code.

d6e2315539 Put a safety check in for the secsiz divide for the MB printf. Else 
we get a panic integer divide fault in the kernel if the drive returns
a bogus zero secsize.

943a66f340 Performance improvements from John Dyson. 
1) A new mechanism has been added to prevent pages from being paged
	out called "vm_page_hold". Similar to vm_page_wire, but
	much lower overhead.
2) Scheduling algorithm has been changed to improve interactive
	performance.
3) Paging algorithm improved.
4) Some vnode and swap pager bugs fixed.

63a7486262 Removed EXCLUDE_<driver> for sound drivers so that all sound drivers 
are compiled into kernel.  Users are referred to sound doc for info.

3b2b53aa9a First open: 
now HUPCL set only in bidir case for callin lines
(this prevents set HUPCL on mouse)
comhardclose:
in addition to HUPCL case now DTR dropped for bidir case
if line was active in and no carrier present now.
(this prevents DTR sleep on mouse)

The transfer speed was only set in the retry after error, not  when
switching drives.
