cgd cf83d9e090 lip service to making ISA support machine-independent. This is the first
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.

1995-01-23 04:50:08 +00:00
mycroft 01ce8db055 Fix the problem with identifying cards on warm boot. Partly from Greg Hudson. 1995-01-22 07:37:28 +00:00
mycroft 3dddacd1ce Rearrange tests so `offline' has higher priority than `out of paper'. 1995-01-22 00:12:39 +00:00
jtc 9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
1995-01-19 01:38:36 +00:00

1995-01-18 17:28:07 +00:00
mycroft bb563c9eec Do I/O through iobuf rather than address 0, where applicable. Avoid an extra
copy in devread().
1995-01-18 16:22:35 +00:00

mycroft 58828fe20e For now, continue to treat EISA devices as ISA. Also, add boca. 1995-01-16 11:51:40 +00:00
mycroft fcdbd2bd7b Remove outdated comment. 1995-01-16 10:36:26 +00:00

cgd 8eb9e3f4db trim it a bit to match reality. get completely rid of things not likely
to ever be wanted in this machine's kernel.
1995-01-15 10:04:21 +00:00
mycroft 1044df1576 Add some commentary to the previous. 1995-01-15 03:33:25 +00:00
mycroft b08d9a004d Fix slight oversight in previous. 1995-01-15 03:29:05 +00:00
mycroft 178fb5f48c Oops. Correct asm() spec. 1995-01-15 02:19:12 +00:00
mycroft 1aace6baa6 Duplicate sigreturn() changes. 1995-01-15 02:12:14 +00:00
mycroft 70e588a0f1 Remove prototype of check_selectors(). 1995-01-15 02:11:23 +00:00
mycroft 98fc96ea40 Add some commentary on the previous. 1995-01-15 01:15:04 +00:00
mycroft ecef8fddfa 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
mycroft 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
mycroft 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
mycroft c26ad3af41 Cosmetic changes, and use db_printf() rather than printf(). 1995-01-15 00:46:38 +00:00
mycroft 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
mycroft 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
mycroft 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
mycroft 87d587e640 Simplify some sanity checks. 1995-01-13 14:46:44 +00:00

mycroft fda9731199 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
mycroft 4abdb375bc Minor rearrangement. 1995-01-13 09:40:21 +00:00
mycroft c2bc310a37 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).
