0696821419
Deal with GCC's dead code elimination being suboptimal.
1996-01-07 03:59:28 +00:00
3afeb8d6b0
Make sure interrupts are disabled before jumping to a resume point, to prevent
...
races.
1996-01-07 02:07:07 +00:00
9e6f4ae58a
Remove unused macros.
1996-01-07 02:03:20 +00:00

Build the frame for recursive interrupts manually, and make sure to disable
...
interrupts to avoid races.
1996-01-07 02:02:28 +00:00
7f6d0eaf9b
Put #includes in the right order.
1996-01-07 02:00:31 +00:00
74e1e47aeb
fixed my own pr 1758 -- the floppy drive motor was not being turned off
...
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.
1995-12-28 15:48:57 +00:00
3da4b2a160
The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

051bb183e3
Same as in 1.1 branch.
1995-11-09 08:40:51 +00:00
72805df917
Various changes from John Kohl and me:
...
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.
1995-10-11 04:19:29 +00:00
25f53a986f
Add USERMODE() and KERNELMODE() macros, and use them.
1995-10-10 04:45:03 +00:00
8096b83664
Eliminate soft segment descriptors; instead use a functional interface for
...
creating segment descriptors. Add the duplicate system call gate used by
BSD/OS 2.0 executables. Prototype setsegment() and setgate(), and fix a bogon
caught by this.
1995-10-09 06:34:11 +00:00
9ba33c87cc
Update makefile to handle the fact that keycap.5 was moved out of man5
...
into this directory.
1995-10-08 21:59:43 +00:00
df99cef0ac
Patch from Frank van der Linden to allow kernels with pcvt but without

XCONSOLE to compile. I've been told that this patch has been sent to
Helmuth.
1995-10-08 21:57:39 +00:00

1995-10-07 21:51:42 +00:00
d9789d4225
Overlay our pcvt with pcvt 3.32 sources. All of our fixes have been
...
incorporated into the master sources, so it is unnecessary to resolve
all the conflicts that would occur if we let CVS "merge" the versions.

1995-10-05 14:12:21 +00:00
864f186a4e
Use MAN instead of MAN8 (although it doesn't matter here because vgaio

is neither built nor installed).
1995-09-16 15:52:38 +00:00

svgalib binaries).

Remove pcvt_kbd_raw.
1995-09-03 01:20:33 +00:00
9fc36ab1a4
* Don't scroll by setting the CRT start address when in graphics mode, and
...
make sure to use the right buffer (fixed in the same way as pcvt 3.30)
* Maintain keyboard state locally per VT. This makes sense, enables switches
between VTs with different kbd states, and aids Linux VT emulation.
1995-08-30 00:29:09 +00:00
a084a7d3dd
Remove bogus check in ioctl(fd, VT_RELDISP, VT_FALSE). Needed for
...
Linux VT emul stuff. This fix was already applied in pcvt 3.30
1995-08-27 20:59:00 +00:00
e11b690b80
Require drives 2 and 3 to be explicitly configured.

...
variable.

Fix oversight in previous change; spl*() must also block
...
software interrupts.
1995-08-09 01:47:37 +00:00

Stop using cr0 to flag that the FPU has not been used.
1995-08-06 06:05:28 +00:00
ce7cc0c18a
Move the `used fpu' flag into mdproc, so it can be referenced when a process
...
is swapped out. Implement process_{read,write}_fpregs.
1995-08-06 05:32:59 +00:00

59e990a56b
check CMOS time against base time, for sanity. if CMOS time invalid,
...
warn user and user base time. if base time < 1985, warn the user.
if base time 5 or more years different than clock time, warn user,
and if it's base time that's greater, use it. (The latter case is
handy if one has a machine in which the CMOS battery is dead... I do.)
