mycroft 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.

mycroft 4ea6427a03 Increase size of imask[]. Sigh. 1995-06-04 20:22:50 +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.)

mycroft d16dcced99 Add interrupt sharing types. 1995-01-03 01:19:19 +00:00
mycroft 205d425f2f As pointed out by Bruce, splsoftclock() needs to process pending interrupts
when lowering the priority.  Do this by simply calling splx().  For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does.  This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.

mycroft 895e9ed71a Mostly stylistic change. 1994-05-05 07:39:28 +00:00
cgd a0a7429482 lots of changes: prototype migration, move lots of variables, definitions,
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.
1994-05-05 05:35:42 +00:00
mycroft 3f5e4f423f Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls.
