For now, continue to treat EISA devices as ISA. Also, add boca.

Some general cleanup, and add support for serial terminals, `#ifdef SERIAL'.
1995-01-16 02:50:32 +00:00

Use getc(), not getchar().
1995-01-16 02:21:15 +00:00

Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to
...
more closely match the 386 manual. (Probably the mnemonics should be changed,
too.)
1995-01-15 00:57:50 +00:00
c7c817b91a
sigreturn() and ptrace() security violations will now trap. Deal with those
...
traps by looking at the instruction stream and the stack to see if it looks
like we're returning to user mode, and if so pop to the hooks in locore.s.
This will fail in the case where a pop %ds or pop %es faults when returning
from a fast interrupt, but this should not be possible.
1995-01-15 00:55:25 +00:00
3e8850eab2
Enable CR0_AM on 486s. (We already handled the fault.) This would be more
...
useful if it applied to the kernel.
Avoid btrl when checking AST flag.
Add hooks to recover from errors during any INTRFASTEXIT and simulate a user-
level protection fault.
1995-01-15 00:52:21 +00:00
c26ad3af41
Cosmetic changes, and use db_printf() rather than printf().
1995-01-15 00:46:38 +00:00
8476bee7b5
Do the eflags security check in a cheaper way. Just check that the privilege
...
level of the return cs is correct; don't check the other selectors. (Will
fault later if they are invalid.)
1995-01-15 00:44:19 +00:00
da79b43eae
Move the existing frame pointer calculation into a separate helper function.
...
Eventually this should cause the child to be swapped in if necessary.
Do the eflags security check in cheaper way.
1995-01-15 00:42:01 +00:00
a2dafd0821
Avoid using btrl, and check astpending before the return cs, because it's
...
faster and usually false.
1995-01-15 00:36:37 +00:00

Further cleanup. Back out part of the previous; it's the device's

responsibility to check for partial blocks.
1995-01-13 09:57:39 +00:00

Minor rearrangement.
1995-01-13 09:40:21 +00:00

Change the way sc_skip is used. Fix a bug in the (incomplete) DMA code. Add a

new sc_blkno (which will be useful later).

If transfer goes past end of disk, truncate it.

Clean up bounds_check_with_label(). Round request to sector size in label,
